Abstract
Calcium channel blockers are used worldwide in CAD, hypertension and arrhythemia. As recent international studies show these drugs in addition to cardiovascular effects have immunosuppressive effects and can prolong graft life in transplanted patients. In a single blind prospective trial we studied 30 patients on 120 mg/d Verapamil for at least 3 months compared with 15 patients on placebo. Changes of cell immunity markers were impressive as T suppressor lymphocytes increased and CD4/CD8 ratio decreased significantly compared with placebo (P<0.05). This study confirms that Verapamil reduce cell immunity that may prone human beings to infections and on the other side we can use it in hypertensive patients with organ graft.

Abstract
With the intention of research about culture and autologus graft of epithelial tissue we used 4 french Albino Rabbits with an average age of 2 months. After reproduction on the support in EMEM (Eagle's Minimum Essential Medium) we used this for graft after 4 weeks. This region which grafted total replaced. After fixation of this sample and passing them through various process, histological sections were prepared. These sections were stained with H & E and masson's trichrome and studied by light microscope. We succeeded in graft. We hope in the near future by using the method of epithelium tissue culture improving to treat burned patients.

Abstract
Background: Acne is one of the most common skin diseases especially in adolescence. Different studies have reported unequal rates of facial acne prevalence in different countries and populations. Only a few cases of acne in the trunk area (back and chest) have been reported in literature. Although our clinical experience shows lower prevalence of truncal acne in comparison with facial acne, a community based study is needed to support this experience.
Methods: A total number of 1001 high school students, selected randomly from 5 out of 20 education-ministry subdivisions of Tehran, were included. In each area two high schools (one for boys and one for girls) with almost 100 students per high school were selected. Demographic data, family history and clinical findings were recorded in the questionnaires. Consensus Conference on Acne Classification was used for acne grading.
Results: One thousand one high school students, 503 girls and 498 boys ,were included. Prevalence of acne was 91.1% for face (95%CI: 83-99%), 93.4% in boys and 88.6% in girls. It was 53.4% for back (95%CI: 46-62.2%), 58.5% in boys and 36.9% in girls. Whereas for chest the prevalence was 36% (95%CI: 27-45%), 34.9% in boys and 36.9% in girls. Mean age of the students with truncal acne was 16.1 years where as 15.9 in others. This difference was significant (P<0.05). Positive family history was higher in students with truncal acne (P<0.001).
Conclusion: Truncal acne is less prevalent than facial acne. Acne on the back is significantly higher in boys than girls (P=0.002). Severe forms of acne in back may be more prevalent in boys. Positive family history can increase the risk of truncal acne.

Abstract
Background: I Infections due to Candida spp. have increased dramatically in recent years through a rising number of predisposing factors and immunocompromised hosts. Although Candida albicans is the most prevalent and important causative agent of Candida infections, the importance of C. parapsilosis, C. tropicalis, C. krusei, C. glabrata, C. guilliermondii and C. kefyr have increased significantly as they tend to be more resistant to antifungal agents. Therefore, it is critical that infecting Candida spp. be identified and considered. Furthermore, clinical laboratories may need to expand their yeast identification capabilities in order to facilitate rapid identification of clinical yeast isolates.
Methods: In a discroptive – analytic study, the patients suspected of candidiasis were sampled. Direct examination and culture was carried out for all specimens. The isolated yeast colonies were then identified using various different tests such as culture on corn mealagar tween-80, CHROMagar Candida, and assimilation test by API 20C AUX kit.
Results: In the present study, 304 yeast colonies were isolated from referral patients to mycology laboratory of 304 isolated colonies 204 were identified as C. albicans and 100 were identified as non albicans candida as follow 35% C. parapsilosis, 32% C. tropicalis, 8% C. glabrata, 8% C. kefyer, 6% C. krusei, 3% C. guilliermondii, 3% C. famata, 3% C. lusitaniae, 1% C. zeilanoides and 1% C. homicola. C. parapsilosis was the most frequent species. The result showed that clinical specimens were obtained from various infected sites of body and nail samples (59 cases) were found to be the most frequent among those specimens.
Conclusion: In conclusion, our results suggest that no single phenotypic test has proven to be highly effective for definitive identification. Moreover since these organisms can vary greatly in their susceptibility to the current antifungal agent and causing significant patient management problem therefore evaluation of susceptibility of these isolates against antifungal drugs is need to be investigated.

Abstract
Background: Pain control after posterolateral thoracotomy is very important for adequate respiration and to reduce pulmonary complications. Narcotic-induced respiratory depression requires different intercostal nerve block procedures with local anesthesia, such as bupivacaine, through an extrapleural catheter, paravertebral catheter and intrapleural injection in order to control pain and reduce narcotics consumption. The aim of this study is to determine the efficacy of bupivacain versus normal saline (N/S) in pain control after thoracotomy.
Methods: In a single-blind clinical trial, forty patients were divided into two groups of 20 patients each. Group 1 (G.1) received a single dose (10 ml) of bupivacaine 0.5%, followed by continuous infusion of N/S (0.1 ml/kg/h) four hours after surgery. Group 2 (G.2) received a single dose (10 ml) of bupivacaine 0.5%, followed by a continuous infusion of bupivacaine (0.1 ml/kg/h) four hours after surgery. Postoperative pain was assessed every four hours for 48 hours by linear visual analog scale (VAS). If VAS > 5, then pethidine was injected at a dosage of 1 mg/kg/IM. VAS ≤ 3 was considered pain control.
Results: TThe mean VAS at 8, 12, 16, 20 and 24 hours after surgery in G.1 was 7.6, 5.5, 6.6, 5.5 and 5.7, respectively, and in G.2 was 3.4, 3.7, 2.8, 2.1 and 1.9, respectively. There were significant differences between the two groups (for 12 hours P<0.001 and for other time points P=0.0001). During the 4-24 hour period after surgery, pain control in G.1 was 5% and in G.2 was 81%. The mean VAS at 28, 32, 36, 40, 44, and 48 hours after surgery in G.1 was 5.2, 5, 5.3, 4.4, 5.1, and 4.8, respectively, and in G.2 was 1.6, 1.8, 1.5, 1.6, 1.5 and 1.4, respectively, with a significant difference between the two groups (P<0.0001). In the first 24 hours, the mean of pethidine injection in G.1 was 3.7 and in G.2 was 0.6 (P<0.0001). In the second 24 hours, the mean pethidine injection in G.1 was 2.2 and in G.2 there was no need for pethidine (p<0.0001).
Conclusion: Continuous extrapleural infusion of bupivacaine is effective in pain control and decreasing demand for narcotics after thoracotomy.

Abstract
Background: The Fontan operation is the definitive operation for palliation of complex congenital heart disease with single –ventricle physiology. The use of the extra cardiac conduit has recently been gaining popularity. The purpose of this study was to compare the outcomes of extra cardiac conduit Fontan procedure (off-pump technique) and that of traditional technique (lateral tunnel technique) in which cardiopulmonary bypass is routinely used.
Methods: Forty one patients in different age groups underwent extra cardiac conduit Fontan procedure between April 2001 and December 2004. Data were collected from ICU sheets, files and during follow up visits. Under general anesthesia and through median sternotomy, using two temporary decompressing shunts, superior vena cava implanted on right pulmonary artery and a conduit interposed between transected inferior vena cava and main pulmonary artery. Fenestration was done in almost all patients and previous shunts were closed if there were any.
Results: Of our patients, 13 were female and 28 were male. Mean age of the patients was 11.1 years (SD=7.8).In 24.4% of cases Fontan procedure was done as the first palliative surgery and in 75.6% of them there was previous history of palliative procedures. In 6 patients (14.6%) we were constrained to use cardiopulmonary bypass which was predictable or necessary in 50% of cases. There was no reoperation due to post operative bleeding. Two cases suffered from prolonged plural effusion. Our in-hospital mortality was 9.8%. During 2-24 months follow up, we found two cases who were in NYHA functional class II and one case in functional class I.
Conclusion: Extra cardiac conduit Fontan procedure could be used in a safe way. The results of this study were comparable and even in some cases better than that of the traditional technique.

Abstract
Background: Lead poisoning has proven to be one of the most important environmental health problems among developing countries with both direct and indirect effects on human life. Lead is known to cross the blood-brain barrier and placenta, and accumulates in soft and hard tissues. Lead can be excreted in urine, stool, milk, sweat, nails and saliva. During pregnancy and lactation, lead is released from bones into the blood along with Ca2+. The toxic effects of lead on various human tissues have been studied extensively, but few studies have addressed its impact on fetal development during pregnancy. Blood levels of lead are higher in people living in lead-polluted regions. It has been reported that Tehran (central and southern parts) is the most problematic city in terms of lead poisoning.
Methods: From 86 sets of mothers and newborns in a non-polluted area of rural Rasht, Iran, we examined specimens of maternal blood, cord blood and colostrum (86×3=258) and specimens from 85 sets of mothers and newborns in a polluted area of Tehran, Iran (85×3=255) for lead levels using atomic absorption spectrophotometry (AAS) and analyzed the results by t-test, SPSS, and linear regression.
Results: The mean blood lead concentrations of mothers, cord blood of newborns and colostrum were 7.6±4.1, 5.9±3 and 4.2±2.5 μg/dl, respectively, in the non-polluted area and 9.1±8.4, 6.5±5.2 and 5.8±5.5 μg/dl, respectively, in the polluted area. The mean weights of the newborns in non-polluted and polluted areas were 3.2±0.5 kg and 3.2±4.5 kg, respectively.
Conclusions: Our data revealed an association between mean concentrations in blood lead of mothers and newborns and between mean concentrations of colostrum lead and newborn blood lead in both areas (p=0.01). There was no association between mean blood lead concentration of mothers with the weight of their newborns (p=0.89).

Abstract
Background: Management of acute abdomen usually does not necessitate accurate pre-operative diagnosis but the surgeon should make a decision about the need for emergent laparotomy. This fact is somehow different for localized peritonitis (e.g. acute appendicitis) in which the clinical presentation directs straightly to the diagnosis. However, acute appendicitis has lots of differential diagnoses, finding the normal appendix during laparotomy is just a start point to look for other diagnoses. Omental torsion is a rare cause for acute abdomen that is usually missed. Knowing about this rare condition and its frequently encountered presentation at the operating room (sero-sanguinous fluid coming out of peritoneal cavity) may prevent missing the diagnosis and doing a malpractice.
Case report: Report a 9 year- old boy presented with acute abdomen which turned out to be an omental torsion after the operation.
Conclusion: Knowledge about this rare condition "omental torsion" and its clinical and intra operative presentations may prevent missing the diagnosis and a malpractice.

Background: Appendicitis is more common during the second
and third decade of life and appendectomy scar is important in terms of
cosmetic issues. The scar is an important factor in the patient's satisfaction.
Conventional teaching has an emphasis on the closure of skin incision with
"separate" sutures. The aim of this study was to reconsider this dogma.
Methods: Among 321 patients with acute
appendicitis who came to the emergency unit of Imam Khomeini Hospital in
Tehran, Iran since april 2007
till april 2008, 278 (86.6%) patients had
uncomplicated appendicitis and were enrolled in our clinical trial. The
patients were randomly assigned to two groups of interrupted suture closure (n=139) and subcuticular
suture closure (n=139). Anesthesia method and
surgical technique were similar between the two groups. All patients were
followed up post-operatively (four weeks) for the presence of infectious
drainage, pain, erythema, swelling and warmness at the surgical site.
Results: The patients' sex and
their mean age were not statistically different between the groups. There was
no significant difference in the frequency of surgical site complications between
the two groups (five cases in the "interrupted" group and eight cases in the
"subcuticular" group p=0.415).
Conclusion: This study showed that
appendectomy incision closure with subcuticular sutures did not increase the
risk of wound complications. From the point of better cosmetic outcome of
subcuticular sutures, this method may be the method of choice for the closure
of appendectomy incisions in uncomplicated appendicitis.

Abstract
Background: Based on the reports, high frequency of special alleles of HLA class II genes might be associated with susceptibility to or protective from a particular cancer. These alleles might vary depending on the geographical region. Here we investigate the association between alleles of HLA class II genes and breast cancer in Iranian women.
Methods: 100 patients with pathologically proved breast cancer who referred to Cancer Institute, Tehran University of Medical Sciences in Tehran, Iran, were divided to two groups based on ages (40 years old and less/ or more than 40 years old) and were randomly selected and compared with a group of 80 healthy blood donor subjects. HLA class II alleles were determined by amplification of DNA with polymerase chain reaction (PCR) method followed by HLA-typing using sequence-specific primer (SSP) for each allele.
Results: The most frequent alleles in the DR and DQ regions in group 1 (40 years old and less) in comparison with control group were HLA-DQA1*0301 (p=0.002) and HLA-DQB1*0302 (p>0.05). In contrast HLA-DQA1*0505 (p=0.004) had significantly lower frequency in this group compared with control group. Patients of group two (more than 40 years old) had a higher frequencies of HLA-DQA1*0301 (p=0.001) and HLA-DRB1*1303 (p=0.02) and a lower frequency of HLA-DQA1*0101 (p=0.002) compared to healthy control.
Conclusion: These findings provide information of a positive and negative association between certain alleles of HLA class II and breast cancer in our population and also might support that the pattern of inheritance in the early and late onset of breast cancer differ substantially.

Abstract
Background: The role of reactive oxygen
species (ROS) in the pathogenesis
of different cardiac diseases has been documented. Recently, effect of
allopurinol in decreasing the production of ROS and
improving cardiovascular pathogenesis has come into scientific interest. Animal
studies have documented the benefit of allopurinol in improving left
ventricular dilatation, hypertrophy and fibrosis, and myocardial contractility
and in the prevention of systemic vasoconstriction. The aim of this study was
to evaluate the effect of allopurinol in improving diastolic dysfunction in ESRD
patients with hyperuricemia.
Methods: This was an interventional study on 28 patients
(19 males and 9 females)
with ESRD and hyperuricemia. At the end of a one-month
course of allopurinol therapy (100 mg daily),
echocardiographic indices of diastolic dysfunction were measured and compared
to the baseline indices.
Results: The mean level of uric acid was 7.5±0.96 mg/dl. The
mean EF before and after the study were %44.28±%9.8
and %44.64±%9.7, (no significant difference),
Respectively. The two indices of IVCT and
A reversal were shown to have significant
improvement after therapy (p=0.028 and 0.012,
respectively). The grading of diastolic dysfunction didn't improve
significantly after treatment with allopurinol.
Conclusion: Significant
improvement in some of studied indices, reproduced only in male subgroup of
patients that might be related to a better response of males to allopurinol,
however, a longer course of treatment may result in more favorable responses.
Better patient selection in terms of "EF"s
with normal distribution and repeating the study in non-dialysis hyperuricemic
patients may result in more accurate information.

Abstract
Background: An increased risk for invasive infections with encapsulated bacteria such as Streptococcus pneumoniae has been described in patients with chronic kidney disease (CKD) or in those on dialysis. The aim of this study was to evaluate the antibody response to pneumococcal capsular polysaccharide vaccine in CKD patients.
Methods: Sixty-six patients with CKD and 40 healthy individuals were vaccinated with pneumococcal polysaccharide vaccine. The serum antibody response (IgG and IgG2) to the Pneumovax antigens was determined by enzyme-linked immunosorbent assay (ELISA) prior to and four weeks after vaccination.
Results: Out of 66 vaccinated patients with CKD, 14 were found to be hyporesponsive to the vaccine (Group 1). Patients with normal specific antibody response were regarded as respondents and were assigned to Group 2 (n=52). The mean post-vaccination IgG titer
to the pneumococcal antigens in Group 1 was significantly lower than those in Group 2
(P=0.012 for IgG and P=0.02 for IgG2). The increased anti-pneumococcal IgG titer was significantly lower in patients in Group 1 versus Group 2 (P=0.001) or the healthy control group (P=0.005). During the follow-up period of patients, patients in Group 1 developed higher episodes of pneumococcal infections than those in Group 2 (P=0.007). Conclusion: A substantial proportion of patients with chronic kidney disease fail to mount an adequate antibody response to pneumococcal antigens and remain at significant risk for such infections. These patients should be offered other prophylactic measures to protect them against invasive pneumococcal diseases.

Background: Hemorrhoid
is among the most common anorectal diseases and patients with high-grade disease
conditions need surgical treatment. Many surgical procedures are available to
treat the disease. The aim of this study was to compare the operative time and
outcomes, (post-operative pain and complications) of LigaSure hemorrhoidectomy
with those of the open conventional method.
Methods : This randomized single-blind clinical trial included 57 patients (28 in LigaSure and 29 in the open group). The
primary variable was the operative time for the excision of a single
hemorrhoidal packet. The other variables were post-operative pain measured by
morphine doses administered to control pain, scores of visual analogue scale (VAS) used to measure pain severity,
pain during home stay measured by doses of oral ibuprofen and the mean daily VAS scores, early complications
including bleeding and urinary retention, longer-term complications and time to
return to work.
Results : The demographic data were comparatively the same between the two
groups. The average time to excise a single packet of hemorrhoid was
significantly shorter in the LigaSure group (8.91
min vs. 17.35 min, P<0.001). Post-operative pain
measurements (morphine doses and VAS scores) were lower in the LigaSure group, but the differences were
not statistically significant (P=0.055 and 0.077, respectively). Complications of the two procedures were also comparable.
Neither of the groups returned to work in a shorter time.
Conclusion: LigaSure
hemorrhoidectomy seems to be a safe method and it can reduce the operative time
significantly. It may also have a modest effect on post-operative pain.

Abstract
Background: Fumonisins, a family of mycotoxins, are mainly found in wheat, corn and their products. Previous studies have shown that fumonisin B1 (FB1), the most abundant and toxic of known fumonisins, has been associated with many animal and human diseases including cancer. In the present study, the effects of FB1 were examined on the production of inflammatory cytokines in intestine and stomach cell lines.
Methods: This study was performed in the Cancer Research Center of Tehran University of Medical Sciences in 2010. The cell lines of colon adenocarcinoma (SW742) and gastric epithelium (AGS) were purchased from the Pasteur Institute of Iran. The cells were pretreated with different concentrations of FB1 (0 to 100 µM) for 3 days. The cells were later stimulated by lipopolysaccharides. Twenty-four hours after cell induction, the cytokines including tumor necrosis factor-alpha (TNF-α), interlukin-1 beta (IL-1β) and interlukin-8 (IL-8) were measured by ELISA.
Results: Treatment with FB1 induced a dose-dependent decrease in IL-8 production (P<0.05). This decrease was seen in both SW742 and AGS cell lines. Moreover, FB1 induced a dose-dependent increase in the production of TNF-α and IL-1β in both cell lines (P<0.05).
Conclusion: The results of this study indicated that FB1 could increase the inflammatory cytokines including TNF-α and IL-1β in gastric and intestinal celllines. These effects might result in the development of inflammatory responses and subsequent mucosal atrophy in in-vivo conditions.

Abstract
Background: Acute lymphoblastic leukemia (ALL) is the most common malignancy in childhood, characterized by excess lymphoblasts, and immature white blood cells that are continuously multiplying and overproducing in the bone marrow. The aim of this investigation was to measure the sensitivity of lymphocytes against gamma irradiation in patients with acute lymphoblastic leukemia, and also find out the effect of such irradiations in causing chromosomal abnormalities.
Methods: In this investigation performed between April 2010 and July 2011, at the Department of Genetics, Cancer Institute of Iran, we studied the effects of gamma irradiation on the lymphocytes of 20 children with acute lymphoblastic leukemia. The lymphocytes of 30 healthy donors were used to establish as a normal response to gamma irradiation and seven age-matched ataxia telangiectasia patients were recruited as positive control. The chromosomal radiosensitivity was assessed with the G2- and the G0-assay. We compared the mean number of chromosomal abnormalities such as chromosome and chromatid breakages, chromosome and chromatid gaps, and chromatid exchanges in one-hundred metaphases of patients and control groups.
Results: The frequency of chromosomal aberrations was statistically higher among patients with acute lymphoblastic leukemia than the normal controls (P<0.01). In total, 65% of the patients were sensitive to gamma irradiation, but the remaining 35% were similar to the normal controls. Patients with ataxia telangiectasia showed the highest sensitivity to gamma irradiation (P=0.001).
Conclusion: Our results showed that a high percentage of patients with acute lymphoblastic leukemia were sensitive to irradiation, meaning that maximum care should be taken during their treatment to avoid unnecessary X-rays or radiotherapies.

Abstract
Background: Previous studies indicate that morphine dependent and withdrawal from chronic opiates enhanced anxiety-related behaviours in novel and stressful conditions in rats. Recent studies have shown that exposure to a stressor generates a wide variety of adaptive responses, while enhancing abilities to adopt with the stressor. Therefore, the aim of this study was to examine the effect of chronic restraint stress and acute water immersion (WI) stress on the anxiety profile in morphine-dependent rats.
Methods: Thirty two rats were injected with twice daily doses (10 mg/kg, subcutaneous, at 12 hour intervals) of morphine over a period of 10 days in the presence or absence chronic restraint stress (1 hour/day). On day 11, two hour after morphine injection, anxiety-like behaviours were tested in the elevated plus-maze model in the presence or absence acute water immersion stress. Rats were divided into four groups: dependent- No restraint stress (D/NRS), dependent- restraint stress (D/RS), dependent- restraint stress+ water immersion stress (D/RS+WI), dependent- water immersion stress (D/WI).
Results: Finding have shown that D/RS+WI rats exhibited an increase in the elevated plus-maze open arm entries and time as compared with the control groups (P=0.018 and P=0.037, respectively). Also, this measure was significantly lower in the WI rats than the D/RS+WI rats (P=0.049 and P=0.031, respectively).
Conclusion: Our findings indicate that chronic restraint stress followed by acute water immersion stress decreases the severity of the anxiogenic-like behaviours in morphine dependent rats thus it may have a therapeutic application in the treatment of the asso-ciated disorders in addiction.

Abstract
Background: Rotational deformity after intramedullary nailing is a well-known complication. Femoral malrotation is the most common form of mal::::union:::: but it is underrecognized in part because of the difficulty in accurately assessing rotation as well as the variation that exists in normal anatomy. The aim of this study was to evaluate femoral malrotation following intramedullary nailing of the femur.
Methods: We studied 70 patients who had referred to Imam Khomeini Hospital and had undergone antegrade intramedullary fixation for isolated femoral shaft fracture during 3-year period from 2008 to 2011. Inclusion criteria including isolated femoral shaft fracture that had undergone antegrade intramedullary nailing. Exclusion criteria including spontaneous ipsilateral tibial fracture or pelvic fracture, contralateral femoral fracture, femoral fracture that had fixed using plate or external fixator or retrograde intramedullary nailing. During operation, the patients were assessed clinically for rotational deformity and then in the postoperative follow-up period, degree of rotation was identified with CT scan. Postoperative computed tomography measurements of rotation were compared with the opposite side.
Results: There were 70 patients, 56 men and 14 women. The average age of the patients was 28.21±14.39 patients (55/7%) had external rotation and 31 patients (44/3%) had internal rotation. The mean of malrotation degree in physical examination was 4/67 and The mean of malrotation degree in CT scan was 7. Degree of malrotation deformity, less of 5º, 5 to 10º and 10 to 15º was less of 8.6%, 75.7% and 15.7% respectively. Degree of malrotation didn’t relate to age, sex, fracture location and activity of the patients (P> 0.05).
Conclusion: Rotational deformity in 28% of the patients was equal to more 15º. This complication didn’t relate to fracture location. The patients with external rotation deformity had more symptoms than the patients with internal rotational deformity but there isn’t significant relation in this study.

Abstract
Background: Uterine leiomyoma is one of the most common benign smooth muscle tumors occurring in 20-40% of women worldwide in their reproductive years. Recent studies revealed that estrogen plays an important role in the pathogenesis of this disease. Since glutathione S-transferase (GST) gene family are involved in the biosynthesis of estrogen, the prior probability that variants at this locus are associated with uterine leiomyoma is likely to be above the null. Therefore, this study was carried out to examine whether GSTP1 polymorphism (Ile105Val) is associated with increased risk of uterine leiomyoma in Iranian population.
Methods: In this case-control study, 50 women diagnosed with uterine leiomyoma and 50 healthy controls were recruited from subjects referred to the Pasteur Institute of Iran from November 2012 to September 2013. The genomic DNA was extracted from peripheral blood leucocytes using the standard phenol-chloroform method and subsequently the GSTP1 polymorphism was genotyped using amplification refractory mutation system-polymerase chain reaction (ARMS-PCR). Logistic regression analysis was applied to estimate odds ratios and 95% confidence intervals after age adjustment using the SPSS statistical software package, version 18.0.
Results: The results showed significant differences between case and control groups in terms of genotype frequency (P<0.0001). In addition, the results indicated that the presence of the valine allele significantly increased risk of uterine leiomyoma about three times more in individuals carrying the mutant allele compared to control group (Odds Ratio: 3.34 95%CI: 1.82-6.15 P<0.0001).
Conclusion: To our knowledge, this is the first study performed in Iranian population assessing the association between GSTP1 Ile105Val polymorphism and risk of uterine leiomyoma. However, further extensive studies with a large number of samples from different populations and ethnicities are required to validate the results obtained in this study.

Abstract
Background: Helicobacter pylori vacA (vacuolating toxin A) gene is comprised of mid- (m), intermediate- (i) and signal-regions. Recently, the vacA-i region genotype has been suggested to be a better predictor of disease severity than either the s- or m-region. The main aim of the present study was to determine the associations of i region poly-morphisms of vacA gene with gastric cancer (GC) and peptic ulcer disease (PUD) in Azerbaijan Province patients.
Methods: A number of 89 patients were enrolled. The biopsy samples were taken from patients referring to the endoscopy units of Imam Reza and Shahid Madani Hospitals, Tabriz, Iran from August 2012 to May 2013. The genotype frequencies of vacA-i1 and i2 in were studied using polymerase chain reaction (PCR).
Results: The frequency of vacA-i1 and i2 was 51.68% and 48.31%, respectively. The genotypic frequency of vacA-i1 in patients with GC (21/24, 87.5%) was significantly higher than in those with non-atrophic gastritis, NAG (19/48, 39.58%). In contrast, the genotypic frequency of vacA-i2 in patients with NAG, PUD, and GC was 60.42%, 64.70%, and 14.28%, respectively. The results of multiple linear and logistic regression analyses confirmed the intensity of correlation of vacA-i1 allele with GC compared with control group (NAG). No significant correlation was found between the vacA-i-region alleles and PUD risk.
Conclusion: We have proposed that the H. pylori vacA-i1 genotype could be an im-portant biomarker for predicting the gastric cancer risk in Azerbaijan Province in Iran. However, due to the difference in the allelic frequency of this gene in H. pylori strains from different parts of the world, the vacA-i1 genotype usefulness in predicting the gas-trointestinal diseases is dependent to the geographic origin of the strains.

Abstract
Background: Uterine myomas are benign tumors of the uterus and the most common solid pelvic tumors causing symptoms in approximately 25% of women in their reproductive years. However, its etiology and pathogenesis remain obscure there is increasing evidence that endometriosis is inherited as a complex genetic trait. Recent studies indicated the involvement of glutathione S-transferase M1 (GSTM1) gene in the pathogenesis of this disease and current investigations are devoted to the other members of phase II detoxification system genes such as glutathione S-transferase T1 (GSTT1). Therefore, current study was carried out to investigate the distribution of GSTM1 and GSTT1polymorphisms in Iranian population in order to estimate possible impact of null-alleles of each gene in development of this disease.
Methods: In this study, 50 patients with endometriosis diagnosed by both pathology and laparoscopic findings according to the revised American Fertility Society classification of endometriosis were recruited from subjects referred to the Pasteur Institute of Iran between November 2012 to September 2013. Accordingly, controls (n=50) were subjects without any of aforementioned gynecologic conditions. The genomic DNA was extracted from peripheral blood leucocytes using the salting out method and GSTM1 and GSTT1 genotyping for gene deletions were carried out using Gap-polymerase chain re-action. Logistic regression analysis was applied to assess whether there was any significant risk increase between the case group with higher null genotypes compared to control group. The level of statistical significance was set at 0.05 and all analyses were conducted using the SPSS version 18.0 (SPSS Inc., Chicago, IL).
Results: There was significant evidence that the distribution of the GSTM1 and GSTT1 genotypes differed between the patients and the controls with an allelic odds ratio (OR) of 3.56 (95%CI: 1.35-9.37, P=0.01) and 3.92 (95%CI: 1.4-10 P=0.009) respectively. Data analysis also revealed that individuals with both GSTM1 and GSTT1 null genotypes (-/-) had higher risk to develop the disease in comparison to the people with the both present (+/+) genotype (OR:19.23, P=0.007).
Conclusion: The findings suggest that the GSTM1 and GSTT1 genetic polymorphisms are associated with the development of endometriosis in Iranian women which is in agreement with previous results obtained in other populations. However, the ethnic variations of polymorphisms should be evaluated in detail and differences should be incorporated into investigations of susceptibility variants for this disease.
