Background: Leg cramp is the painful contraction of the muscles
that often occurs at night. Pregnancy is the most common cause of muscle cramps
that usually occur in the second trimester of pregnancy. Although the reasons
of the spasms had not been determined, the imbalance between the absorption and
elimination of serum electrolytes such as Ca, Mg and potassium and also insufficiency of some vitamins
and probably the changes in activities of motor neurons of spinal cord, can be
the source of these problems. The aim of this study was the evaluation of frequency
and predisposing factors of leg cramps.
Methods: In a cross sectional descriptive analytic study, a
group of 400 women in the third trimester of pregnancy were asked
to record the symptoms of leg cramp. Their education level and job recorded and
their total serum level of Ca and Mg was measured in the first visit. Exclusion criteria
included systemic medical conditions such as thyroid disease, diabetes, osteoporosis
and prenatal disorders such as gestational diabetes mellitus and preeclampsia
and patient cooperation.
Results: In our study the prevalence of leg cramp was 54.75%. There was a statistically significant relationship
between leg cramp and serum level of magnesium (p=0.04). There was no relation between calcium serum level
and leg cramp (p=0.294). The women's age, their nutritional habits and
individual characteristics were not signify-cantly related to occurrence of leg
cramp.
Conclusion: Leg cramp is a common
symptom in pregnancy and in patients with low serum levels of magnesium, a
magnesium supplement can be helpful.

Background: Clefts of the lip and palate are one of the
most common congenital birth anomalies. Genetic factors play a great role in
the etiology of them and the high percentage of the consanguineous marriage of
the parents of the affected persons is one of the reasons. These defects not
only make abnormal changes on appearance of the neonate, but also make a lot of
stress and psychological problems for the patients and their families. Study on
the prevalence of clefts, their risk factors and also genetic counseling for
affected persons and their families can be a guideline for general population
and probably reduce these anomalies over the generations.
Methods: Patients referred to
the Department of Genetics, Imam Khomeini Hospital, Tehran, Iran were studied. A
total of 7374 pedigrees of all the
patients admitted to the Department, were studied during 2002-2005 and 99 pedigrees with the
patients with cleft lip± palate or isolated
cleft palate were separated. The total number of cases among these 99 pedigrees was 136. The effects of
consanguineous marriage, positive family history and sex were investigated
among cases.
Results: 70.8% of patients with
syndromic clefts and 58.7% of patients with nonsyndromic CL±P had parents with
consanguineous marriage. In addition 44.4% of patients with nonsyndromic CL±P
had positive family history.
Conclusion: In our population
prevalence of nonsyndromic CL±P was
estimated to be 7 in 1000 (with 95% Confidence Interval was
between 5 & 9) and prevalence of
nonsyndromic CP was about 3.1 in 1000 (with 95% Confidence Interval was
between 1.8
& 4.4).
Consanguineous marriage of parents seems to have a significant role (p=0.02) on prevalence of the
clefts.

Background: American pediatric Association proposes to
screen all neonates with Oto-Acoustic Emission (OAE). In developing countries, because of several limitations,
health policy makers recommend to screen only in high risk patients. This study is performed with the aim to screen
hearing loss in 950 high risk newborns hospitalized in hospitals
affiliated to Tehran University using the OAE test.
Methods: A total of 950 neonates hospitalized in the Neonatal and NICU wards of
Vali-e-Asr, Shariati, Medical Center and Bahrami Hospitals during the years 2004-2006 who
showed at least one risk factor using TEOAE hearing test were enrolled into this cross-sectional
descriptive analytical study and were diagnosed with mild deafness and total
deafness. Blood exchange due to hyperbillirubinemia, septicemia, congenital
heart disease, the fifth minute apgar scores below six, PROM more than six hours, epilepsia, need to NICU more than five hours, pneumonia and Oto-Toxic drugs
were considered as risk factors. Data was past medical history, current
disease, admission cause, sign & symptoms and complications of disease.
Results: Multivariate logistic regression and paired t-test
showed that blood exchange, low birth weight and low first minute Apgar scores
had the highest independent risk for hearing loss among newborn.
Conclusion: Despite of the low prevalence of neonatal hearing loss,
screening of hearing loss at early stages is important.

Abstract
Background: Inhibin is a dimeric glycoprotein that has a depressive effect on the anterior hypophys secretion. The level of this tumor marker is undetectable in menopause women. In patients with gynecological cancer, especially granulosa and epidermal-type (mucinous), ovarian cancers considerable increase in the serum level of inhibin has been reported. The increased level of inhibin has been reported in patients with recurrent ovarian cancer.
Methods: We measured total serum inhibin and CA125 tumor marker level in 38 postmenopausal women with pathologically confirmed ovarian cancer before and after surgery out of 51 suspected women. Our control group were postmenopausal women that attended to our clinic for routine gynecologic check up. Both tumor markers were measured in these patients too.
Results: Among 38 women with ovarian cancer, 13(34.2%) had elevated serum levels of total inhibin. Among the 16 women with serous adenocarcinoma, 3 patients (18.8%) had elevated serum levels of inhibin. All the three women with granulosa cell tumor had elevated serum levels of inhibin (100%) and 3 of 4(75%) women with mucinous ovarian cancer had the same result. three out of 38 women in control group had elevated serum levels of inhibin. Among all 38 patients, 6(15.7%) showed tumor recurrence, that all were concomitant with rising of both serum CA125 and Inhibin levels (p=0/001). Conclusions: Serum inhibin level is a usefull tumor marker in granulosa cell and in mucinous tumor of ovary. In this study combined inhibin and CA125 assay showed better results in early detection of ovarian cancer in comparison to either CA125 or inhibin alone

Abstract
Background: Postpartum depression is a mood disorder that has harmful effects on mothers,
infants, family and relationships. Acute decrease of progesterone after delivery has been proposed as a cause for postpartum depression. This
hormone can affect neurotransmitters' function. Zinc (Zn) and magnesium (Mg) as trace elements exert their antidepressant effects through
neurotransmitter pathways. On the other hand, thiamin (Vit B1) deficiency leads to depression in animal models. The aim of this study
was to evaluate effects of combination of zinc, magnesium and thiamine on postpartum depression and role of nitrergic system.
Methods: One hundred ten female mice in five groups were used. Postpartum depression was conducted using progesterone injections. Combinations of
Zinc chloride, magnesium chloride and thiamine HCL were administered 30 minutes before open field and forced swimming test (FST). In order to
investigate role of nitrergic system, L-arginine and LNAME were administered.
Results: All treatment groups spent less immobility time than the control group (p< 0.05). Combined administration of Zn+ Mg+ Vit B1 caused the most reduction in immobility time. Administration of L-NAME in Zn+ Mg+ Vit B1 group caused reduction in immobility time while administration of L-arginine caused increase in immobility time in the same group.
Conclusion: Zinc, magnesium and thiamine can improve depressive symptoms by nitrergic pathway. These elements as supplement compounds could be alternatives for antidepressants in postpartum period.

Abstract
Background: Scorpion envenomation is considered as one of the Public Health problems in some countries in the world including Iran. Annually, approximately 30,000 scorpion stings happen in Iran from which 12% belongs to Hemiscorpius lepturus (special small closely spaced, bead-shaped jointed tail, similar in the shape to a cows tail, and is locally called ‘‘gaodim'' (Gao, cow dim, tail)) with 95% mortality. The main treatment is antiserum therapy which is produced in horse and is the only way to neutralize the venom. Due to the anaphylactic shock of the horse antiserum in some of the stung patients other source of antiserum is recommended. In this study the ability of produced camel antiserum in neutralizing the scorpion venom of Hemiscorpius lepturus was performed in Balb/c model.
Methods: Camel is an animal model that genetically is compatible with human genome utilized in this research to produce antiserum against scorpion venom. Two camels were used for immunization with the venom of Hemiscorpius lepturus. ELISA method was used to confirm the immunity. Antiserum was produced and used for neutralizing test. The precipitated antiserum with saturated ammonium sulfate (SAS) was also used to perform the neutralizing test in mice.
Results: The results indicated that the amount of 200 µl of antiserum and 400 µl of SAS antiserum were able to neutralize the amount of 1 LD100 of the venom and the survived the mice from death.
Conclusion: The result indicated that camel antiserum against scorpion venom is capable to neutralize the crude venom in mice model. Due to the safety of camel serum in human, it is suggested that the produced antiserum in camel can be substitute with the traditional horse antiserum in scorpion stung patients.

Abstract
Background: Molecular DNA markers are one of the most important tools in molecular biology labs. The size of DNA molecules is determined by comparing them with known bands of markers during gel electrophoresis. There are many different protocols to produce these kinds of molecular markers. In this study we have suggested an efficient strategy to produce molecular weight markers in industrial proportions.
Methods: To achieve the desired sizes of DNA fragments, a combination of two previously known methods, restriction enzyme digestion and polymerase chain reaction (PCR), were used. The enzymatic digestion process was based on designing and
constructing plasmids which equaled in size with the desired length of DNA fragments
and produced the desired DNA fragment upon linearization. In the PCR method, the desired length of DNA fragments were cloned in multiple cloning sites of pTZ57R plasmid and in a PCR reaction, the new constructed plasmid was used as a template to produce the final fragment.
Results: Upon application of this strategy, 2000 and 3000 bp DNA fragments were produced by enzymatic digestion of plasmids of the same size. Moreover, 100 to 1500 bp fragments were produced during PCR using only a set of forward and reverse
primers at the flanking region of pTZ57R multiple cloning site.
Conclusion: The highest advantage of this cost-benefit approach is to produce different types of molecular weight markers by using an effective and short protocol

Background: Anterior
knee pain is one of the most common complaints of patients in orthopedic
clinics. The first step in the treatment of this problem is conservative
treatment which includes administration of anti-inflammatory drugs, exercise
and changes in life style. Many patients respond well to these measures in
about six months, but a small number of patients may not respond to the conservative
treatment therefore, surgical procedures such as Maquet osteotomy or lateral
retinacular release may be needed in these cases. The aim of this study was to
determine the efficacy of intraosseous drilling and decompression of patella in
the treatment of chronic anterior knee pain.
Methods : This study was performed as a case series on ten patients with
chronic anterior knee pain attending the Orthopedic Clinic of Imam Khomeini
Hospital, in Tehran, Iran in 2009-2010. Eight of the patients were male and the rest were female. The
patients met the inclusion criteria and were followed up for at least 12 months after the surgery.
Results : The mean age of the patients was 27.8±4.66 yr and their mean BMI was 22.5±1.71 kg/m2. The mean pain severity before the interventions
was 8.2±0.78 based on VAS but it decreased to 2.5±1.26 post-surgically. An average
reduction of 5.7 scores were noticed in pain severity depicting a significant
reduction of pain (P<0.0001).
Conclusion: It may be concluded
that intraosseous drilling and decompression of patella is a safe and effective
method in the treatment of chronic anterior knee pain not responding to
conservative treatment.

Abstract
Background: Ischemia/reperfusion induced acute renal failure causes excretory functional disorders of nephrons. Ischemia/reperfusion injury is accompanied by generation of reactive oxygen species that leads to dysfunction, injury, and death of renal cells. Antioxidants of plant origin minimize the harmful effects of reactive oxygen species. The aim of this study was to determine the possible therapeutic potentials of Rosa canina L. in preventing renal functional disturbances during the post-ischemic reperfusion period.
Methods: In this experimental study undertaken for evaluating renal excretory function in 30 male Wistar rats, renal ischemia was induced by occluding both renal arteries for 45 min, followed by 24 h of reperfusion. The rats received 2 ml of tap water or a hydroalcoholic extract of Rosa canina (500 mg/kg) orally for 7 days before induction of ischemia. In plasma samples, creatinine and urea nitrogen levels were measured, and in renal tissue samples, red blood cells were counted. The data were analyzed using ANOVA and Duncan tests.
Results: Renal ischemia for 45 minutes increased plasma levels of creatinine (P<0.001) and nitrogen urea (P<0.01) while reducing red blood cell counts in renal glomeruli (P<0.001). Rosa canina administration diminished the increase in creatinine (P<0.001) and nitrogen urea concentrations (P<0.01), and prevented reductions in red blood cell counts in renal glomeruli (P<0.001).
Conclusion: Rosa canina seems to be useful as a preventive agent against renal damages induced by ischemia/reperfusion injuries in rats.

Abstract
Background: Carotid endarterectomy (CEA) is a standard method for patient with significant carotid stenosis but direct surgical repair via carotid endarterectomy may not be a good option in some patients because of the overall health status that may make the surgery too risky. Carotid angioplasty and stenting (CAS), is a relatively new procedure for the treatment of carotid artery disease in patients who may not be fit enough to undergo surgery. In this investigation, we determined short- and long-term outcomes of stent angioplasty in high-risk patients for whom the risk of perioperative morbidity and mortality is high.
Methods: We have followed 82 consecutive symptomatic patients with a ≥50% and asymptomatic patients with a ≥70%- 80% carotid stenosis within 15.9 months of angioplasty and stenting in Baqiyatallah and Jamaran hospitals from 2008-2010. All the patients were considered poor surgical candidates by experienced surgeons and anesthesiologists upon pre-surgical consultation.
Results: This descriptive cross-sectional study was performed on 28 women and 54 men with a mean age of 69.7±9.2 years. The procedure was technically successful in 79 (96.3%) cases. There were 6 (7.3%) deaths, 5 (6.1%) strokes, 4 (4.9%) MIs and 4 (4.9%) TIAs during the follow-up period.
Conclusion: The clinical results during the short available follow-up period suggested stent angioplasty to be useful, effective, reliable and safe in the treatment of significant cervical carotid stenosis in high-risk patients. Further analytical investigations with longer follow-up periods for predicting risk factors are recommended.

Abstract
Background: The 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhi-bitors (statins) have revolutionized the treatment of hypercholesterolemia. Some evide-nce indicated the role of nodal refractoriness and concealed conduction in anticipating the ventricular rate during atrial fibrillation. Recent evidence has indicated that statins can reduce the incidence of both supraventricular and ventricular arrhythmias. The aim of the present study is to investigate adenosine A1 receptor role on simvastatin protecti-ve effects on atrioventricular nodal properties in isolated atrial fibrillation model of rabbit heart.
Methods: The present study was performed in cardiovascular research center of Golestan University of Medical Sciences in 2012. Recovery and atrial fibrillation protoc-ols were used to study electrophysiological properties of atrioventricular node in 5 groups of male Newsland rabbits (n=40). Extracellular recording was carried out from transitional cells of posterior and anterior extension of AV-node and upper part of atrium and its bundle. All stimuli protocols repeated in the presence of adenosine A1 receptor agonist and antagonist (dipridamole and CPX) alone or with simvastatin on isolated perfused atrio-nodal preparation. Extracellular field potential recording was sampled during specific stimulation protocols.
Results: Significant inhibition was observed in basic node properties such as wencke-bach prolongation, functional refractory period, effective refractory period and atriove-ntricular node conduction time with simvastatin (P<0.05). Simvastatin prolonged His-His interval and increased number of concealed beat in atrial fibrillation protocol (P<0.05). The simvastatin protective effects on atrioventricular nodal properties were intensified by dipridamole as an adenosine A1 receptor agonist (P<0.05), but CPX as an adenosine A1 receptor antagonist could only dampen them (P>0.05).
Conclusion: Our results showed that the use of adenosine agonist increased simvastatin effects on electrophysiological properties of atrioventricular node, but its antagonist could not prevent these effects. This may indicate simvastatin protective mechanism on atrioventricular node electrophysiological properties without adenosine direct involve-ment.

Abstract
Background: The purpose of this study was evaluation of risk factors of peripheral artery disease (PAD) and effective markers on it.
Methods: This descriptive-analytical study was done during 2010-2011 in the surgical units of Khorramabad Shohada Hospital. Fifty patients who had symptoms of PAD undergoing CT angiography and biochemical markers for them were measured. The investigated variables were family history, site of arterial obstruction, underlying diseases, smoking history, physical activity and stress level. A control group was considered for the study. The comparison was made between these two groups.
Results: Aging showed a significant role in prediction of PAD (70% sensitivity and 64% specificity). Homocysteine had the highest sensitivity (80%) in prediction of PAD, compared with other biomarkers. CRP (74% sensitivity) was the best marker that had positive predictive value for PAD. Fasting blood sugar (FBS) showed a significant role in prediction of true positive cases of PAD (72% sensitivity and 74% specificity). HbA1C with 68% sensitivity and 64% specificity and TG with 50% sensitivity and 44% specificity could be considered as factors related with PAD.
Conclusion: The levels of C-Reacative protein, homocysteine, and FBS were correlated with PAD, HbA1C and TG levels were associated with PAD, but lower than the previously named markers. In this study a significant relationship between lipoprotein levels and PAD was also observed. PAD was associated with sex and age.

Abstract
Background: Intrauterine insemination (IUI) is one the most common methods in infertility treatment, but its efficiency in infertile couples with male factor is controversial. This study is a retrospective study about correlation between semen parameters and male and female age with successful rate of IUI in patients attending to Royan Institute.
Methods: A total of 998 consecutive couples in a period of 6 months undergoing IUI were included. They were classified into two groups: couples with successful and unsuccessful pregnancy. Main outcome was clinical pregnancy. Data about male and female ages and semen analysis including concentration, total sperm motility, class A motility, class B motility, class A+B motility and normal morphology was extracted from patients’ records. Semen samples were collected by masturbation or coitus after 2 to 7 days of abstinence. Their female partners were reported to have no chronic medi-cal conditions and have normal menstrual cycles.
Results: One hundred and fifty seven of total 998 cycles (15.7%) achieved pregnancy. The average of female age in successful and unsuccessful group was 28.95±4.19 and 30.00±4.56 years, respectively. Mean of male age was 33.97±4.85 years in successful group and 34.44±4.62 years in unsuccessful group. In successful and unsuccessful groups, average of sperm concentration was 53.62±38.45 and 46.26±26.59 (million sperm/ml), normal morphology of sperm was 8.98±4.31 (%) and 8.68±4.81 (%), sperm total motility was 47.24±18.92 (%) and 43.70±20.22 (%) and total motile sperm count was 80.10±63.61 million and 78.57±68.22 million, respectively.
Conclusion: There was no significant difference in mean of females’ age and males’ age between successful and unsuccessful groups (P<0.05). In addition, there was no significant difference in semen parameters including concentration, total sperm motility, class A motility, class B motility, class A+B motility and normal morphology between two groups. It was shown that common semen analysis and male and female ages cannot predict IUI outcome.

Abstract
Background: Colorectal carcinoma is a common malignancy, in treatment of which pelvic radiotherapy plays an important role. But this may lead to azospermia. We designed a study to determine the delivered dose to the testis with thermoluminescence dosimetry (TLD) and compare it to the dose calculated by the Three-dimensional planning software.
Methods: We measured the testicular doses by TLD the TLDs were fixed to the scrotum in six points anteriorly and posteriorly in two random fractions of the radiation course. All patients received a 50-50.4 Gy radiation dose to the pelvis in a prone position with standard fractionation and 3-dimensional planning, through three or four fields. The average dose of the TLD measurements was compared to the average of 6 relevant point doses calculated by the planning software.
Results: In 33 patients with a mean age of 56 years, the mean testis dose of radiation measured by TLD was 3.77 Gy, equal to 7.5% of the total prescribed dose. The mean of point doses calculated by the 3-dimensional planning software was 4.11 Gy, equal to 8.1% of the total prescribed dose. A significant relationship was seen between the position of the inferior edge of the fields and the mean testis dose (P= 0.04). Also body mass index (BMI) was inversely related with the testicular dose (P= 0.049).
Conclusion: In this study, the mean testis dose of radiation was 3.77 Gy, similar to the dose calculated by the planning software (4.11 Gy). This dose could be significantly harmful for spermatogenesis, though low doses of scattered radiation to the testis in fractionated radiotherapy might be followed with better recovery. Based on above findings, careful attention to testicular dose in radiotherapy of rectal cancer for the males desiring continued fertility seems to be required.

Abstract
Background: Traumatic amputation of upper limb above the level of the elbow, are rare injuries that a surgeon may be faced with a handful of cases during his career. Even with advanced techniques in microvascular surgery, the survival of the transplanted limb that cut off completely from the arm is relatively weak.
Case Presentation: Four injured people (patient) in Imam Khomeini Hospital during 1999-2013 in Tehran University of Medical Sciences were treated. Two patients had complete amputation of limb and other patients suffered from complete cutting in artery and vein along with neurological and soft tissue damages. There was not any ischemia or gangrene. However, efficiency of limbs with damages in peripheral nerves was not significant. The main reason was lack of immediate repair of the damaged nerves. In the recent examination, after discharge, the performance of the limb is firstly related to the conditions of the nerve system and secondly it depends on the severity of the injury in each of the muscles. However, none of the patients were dissatisfied of any situation and they were prepared to make any cooperation for improving the condition of their transplanted limb.
Conclusion: Transplantation of the amputated limb can be done in spite of limited resources. Any delay in repairing damaged nerves will result great reduction of final organs’ performance. A limb, made from the own body, always take precedence to prosthesis, even when the efficiency is low.

Abstract
Background: The aim of this study was to assess the role of consolidative intraperito-neal chemotherapy with carboplatin in decreasing relapse and increasing survival in advanced epithelial ovarian cancers, as well as evaluation of its toxicity.
Methods: In this clinical trial 30 patients with epithelial ovarian cancer in stages II-IV who had complete surgery (optimal debulking surgery) received six standard cycles of intravenous carboplatin and paclitaxel. They were enrolled through non-random se-quential selection. The control patients were similar to case group in stage (II-IV) and pathology (epithelial ovarian cancer). The control group was evaluated retrospectively through hospital files. This clinical trial performed in Gynecology Oncology department in Tehran Valiasr University Hospital, during 2005-2010. They including 18 cases as the intervention group receiving intraperitoneal chemotherapy and 12 patients as the control group with only retrospective follow-up. The cases received 3 cycles of 400 mg/m2 intraperitoneal carboplatin every 21 days following intravenous chemotherapy. Relapse of disease was diagnosed as increasing or even doubling CA125 serum titer during one month, or any CA125 above 100 IU, or an abdominal or pelvic mass in ul-trasound or physical exam. Mean survival of two and five years, progression-free inter-val (PFI), overall survival (OS), relapse, demographic parameters, drug toxicities, path-ologic types of cancers in two groups were coded and compared using SPSS 14. Any P<0.05 was considered as a significant difference.
Results: The mean ages of cases and controls were 52.4±8.6 and 55.1±11.5 years. The mean duration of relapse-free survival was 13±8.6 months for the cases and 9.5±4.3 months for the control patients (not statistically different, P>0.05). The mean overall survival for cases and controls were 39±16.5 and 30.8±16.2 months, respectively (no significant difference, P>0.05). The frequency of drug toxicities in the cases was 5.6%, and consisted of mild-to-moderate abdominal pain, nausea and vomiting.
Conclusion: It seems that consolidation therapy with intraperitoneal carboplatin may not increase overall survival, reduce relapse rate or decrease mortality, though it does not induce considerable side effects. Since the mean survival in the intervention group was nine months more than controls, this difference may be clinically significant.

Abstract
Background: The effects of consumption of nutrients on coronary artery disease (CAD) are widely observed. The aim of this study is to assess the exclusive Iranian dietary pattern on coronary artery diseases (CAD) and its risk factors. Methods: In this description-cross sectional study, 801 inhabitants of Borujerd City were included by random stratification method and a questionnaire regarding micro- and macronutrients for subjects over 35 years old from March 2011 to February 2012 was filed out. Of all the subjects consent to participate were prepared by volunteers. The complete description and a standard questionnaire to record demographic and socioeconomic status of people were taken. The prevalence of coronary artery disease and its risk factors determined Based on rose questionnaire and Monica questionnaire respectively. Results: In this study mean age of the subjects were 54.8±1.2 years, 388 male and 413 female. There was no meaningful relation between red meat consumption and coronary artery disease (P= 0.117). Nut consumption was higher in patients with CAD (P= 0.028). Use of fresh and cooked vegetables, dried fruit, animal oils cakes, french fries and some dairies are correlated with CAD (P< 0.05). However, artificially flavored soda in contrast to ordinary soda was not associated with coronary artery disease. Conclusion: Although there are some differences between dietary pattern in patient with coronary artery disease, nutritional attitudes are not significantly different in normal and CAD patients. However, according to the importance of diet in CAD, balancing these attitudes should be on the educational system high priority.

Abstract
Background: There are many genetic and non-hereditary risk factors that are known to causes venous thromboembolic (VTE) disorders, Cardiovascular diseases and types of cancer. One of these is the Prothrombin G20210A mutation. Prothrombin mutation (guanine to adenine G→A) at nucleotide position 20210, which is present in the 3′ untranslated region of the prothrombin gene. Prothrombin G20210A mutation is present outside the coding region for prothrombin, and hence it does not affect the actual structure of the prothrombin molecule and it does not affect its function as a strong clotting factor when activated into thrombin. However, several studies have shown that, G20210A heterozygosity was associated with a threefold increased risk for VTE. Moreover, the association of PTH G20210A polymorphisms with cancer has been reported. The present study was designed to determine the frequency of PTH G20210A polymorphism in Southern Iran.
Methods: In this cross-sectional study, 140 healthy women were from Southern Iran recruited among participants in Namazi Hospital, Shiraz, Iran, from March 2013 to February 2014. A total of 5 ml of peripheral blood was taken from individuals then Genomic DNA was extracted using blood DNA kit (Ron’s Blood and Cell DNA Mini Kit, BioRon, Germany). The amplification refractory mutation system- polymerase chain reaction (ARMS-PCR) method was used for the detection of PTH G20210A single nucleotide polymorphism in each subject.
Results: The frequencies of the GG and GA genotypes were as 97.9%, 2.1% respectively. The frequency of G allele was and the frequency of A allele was 1.1%.
Conclusion: Results of the present study might be important in understanding the distribution of PTH G20210A polymorphism in the Southern Iran. Minor allele frequency in this population is higher than in the Iranian and European population but similar to the prevalence in the Western Iran, Iranian Jews, American, Irish, Tunisian and Bahraini population.

Abstract
Background: Seladin-1 protein protects the neural cells against amyloid beta toxicity and its expression decreased in vulnerable regions of Alzheimer's disease (AD) brains. On the other hand, changes in serum levels of S100 have been considered as a marker of brain damage in neurodegenerative diseases. Furthermore, this study was carried out to determine the relation between the change profile of serum S100&beta protein levels and hippocampal Seladin-1 gene expression in a rat model of sporadic AD. Methods: In this experimental study that established in Department of Neuroscience, School of Advanced Technologies in Medicine, Tehran University of Medical Science, from March 2011 to April 2013, 72 animals were randomly divided into control, 4, 7, 14, and 21days ICV-STZ/Saline administrated rats. Alzheimer's model was induced by intracerebroventricular (ICV) injections of streptozotocin (STZ) [3 mg/kg] on days 1 and 3. Serum levels of S100&beta and hippocampal Seladin-1 gene expression were evalu-ated in experimental groups. The initial and step-through latencies (STL) were deter-mined using passive avoidance test. Results: Serum levels of S100&beta were significantly different between the STZ-7 day and STZ-14 day groups in comparison with the control, saline and STZ-4 day groups. As well as, there was a significant difference between the STZ-7 day group in comparison with the STZ-14 day and STZ-21 day groups (P=0.0001). Hippocampal Seladin-1 gene expression in STZ-14 day and STZ-21 day groups significantly decreased as compared to the control, saline and STZ-4 day groups (P=0.0001). However, significant correla-tion was detected between serum S100&beta protein decrement and Seladin-1 down regula-tion (P=0.001). Also, the STL was significantly decreased in 21 days ICV-STZ adminis-trated rats as compared to the control or saline groups (P=0.001). Conclusion: Monitoring the changes of serum S100&beta protein levels by relationship with changes in hippocampal Seladin-1 gene expression can be a useful indicator of neu-ronal damage in patients with Alzheimer's disease.

Abstract
Background: Cooling is one of the main processes in bone temperature decrement, while drilling. this experiment was conducted for examination of alcohol effect as cooler in prevention of thermal necrosis.
|
Methods: Bovine femur bone was considered as specimen and inclusions criteria for this study were: femur bone, cortical area and without bone periosteum. Drilling process was conducted by two types of k-wire- Trocar and Diamond, three speeds and three feed rates and in the time of march, 2016 in the place of university of Isfahan, Iran. Two type of thermometer- K-thermocouple and infrared thermometer- were used for temperature measurement, and all data were logged by data logger. Drilling processes were conducted by milling machine with ability of table movement for feed rate parameter. Method of alcohol usage in cooling was in form of conducting alcoholic gauze with k-wire while rotating.
Results: Totally in the cases of trocar and diamond wires, while were cooled by alcohol, the risk of bone necrosis decreased about 44.44% and 66.66%. All temperature data were logged by changing parameters. maximum temperature, 94.5 °C, belonged to trocar wire in a non-cooling condition and after usage of cooler it decreased to 75 °C. In the usage of diamond wires, the maximum temperature was recorded 71 °C and the temperature while using alcohol was 51 °C. Diamond wire had better result in both conditions of cooling and no cooling, and this is related to geometric differences between two types of wires.
|
Conclusion: Due to obtained data from examination, utilization alcohol can have an important influence on final bone temperature decreasing. The way of using alcohol was in the style of attrition soaked gauze onto wire while insertion.
