Abstract
This cross-sectional descriptive study was undertaken to know the rate of intestinal parasites infestations in our school children population. A sum of 1155 fecal samples were analyzed from an equal number of children whose age were between 6-11 years old. The percentage of infestations were: Giardia lamblia (14.11%), hymenolepis nana (1.21%), ascaris lumbricoides (0.08%) and enterobius vermicularis (0.08%). We found no differences with regard to sex, age, father and mother levels of education, family size, body mass index (BMI) and the erythrocyte sedimentation rate (ER) between the stools positive and the stools negative cases. Nearly all cases of giardiasis (99.4%) were symptomatic. Eosinophilia was seen in (5.5%) of the infested children with giardiasis and in (0.5%) of the non-infested children, the difference was statistically non-significant (P=0.056). All cases of giardiasis (N=163) were treated with metronidazole 15 mg/kg/day in 3 divided doses for 7 days. Metronidazole was effective in (92.2%) of the treated children.

Abstract
Apium graveolence has an small brown olyptical seed with pharmacological activity. To evaluate it's application in treatment of hypertension, 37 hypertensive patients (20 female, 17 male) with the age range of 45-65 were given 6 grams of powder of Apium graveolence seed and then the blood pressures before and after the remedy were compared. Before treatment, the mean systolic blood pressure was 171.35 mlHg and the mean diastolic blood pressure was 94 mlHg. After they became 154.3 mlHg and 89.6 mlHg respectively. The difference of blood pressure before and after treatment was statistically significant (P<0.05), so we concluded that Apium graveolence seed can be used as is a safe and effective treatment for high blood pressure. Further controlled studies should be done to compare it with available anti-hypertensive drugs.

Abstract
In recent years off-pump coronary artery bypass surgery (OPCAB) has emerged as preferred method for revascularization of coronary arteries in relatively selected group of patients. Considering patients receiving incomplete revascularization need significantly higher postoperative catheterization and re-intervention (PTCA or CABG), we performed this study to identify safety and feasibility of this technique for total revascularization in nearly all patients requiring coronary artery graft surgery.
Materials and Methods: In this study, 150 consecutive patients underwent OPCAB by one surgeon. Octopus device used for regional wall stabilization. Vascular control achieved by ethibond loops, occluder, and shunts. Situations such as cardiomegaly, poor ventricular function, advanced age, hemodynamic instability, and small coronary arteries were not considered contraindications to OPCAB.
Results: Of 150 OPCAB cases, 146 (97.3 percent) were completely off-pump. The mean number of grafts per patient was 4.1 (range, 2 to 6). Total 595 distal grafts anastomosed to LAD (140) diagonals (140), right coronary artery (145), left circumflex (164). Thirty-day mortality and myocardial infarction were 0.6 percent and 3.3 percent respectively OPCAB patient experienced lesser postoperative bleeding had shorter stay at surgical intensive care unit and extubated earlier. Conduits used were left internal mammary artery, radial artery and greater saphenous vein.
Conclusion: OPCAB is a safe method for complete revascularization in nearly all patients. The OPCAB patients experience less complications, have shorter hospital stay, absolute contraindication for OPCAB other than severe, diffuse coronary artery disease with poor run-off which is better treated by cardiopulmonary bypass.

Abstract
Preoperative autologous blood donation is commonly used to reduce exposure to homologous blood transfusions among patients undergoing elective cardiac surgery. The aim of this study was to evaluate the effect of autologous transfusion on patients' hematocryte value, intra and postoperative blood loss, hospitalization time, the development of infective complications and other factors.
Materials and Methods: Between June 2001 to April 2002, 208 patients were underwent cardiac surgery in cardiac surgery ward in Imam Khomeini Medical Center. One or more blood units donate from 104 Patients before cardiopulmonary bypass and heparin injection, and transfused to them after CPB and Protamin injection (autologous Group, group 1). 104 patients underwent cardiac surgery routinely (control group, group 2).
Results: Mean of age was 55.9±8.6 in group 1 and 56.6±9.3 in group 2 (P=NS). 73 male and 31 females were in group 1 and 79 males and 25 females were in group 2 (P=NS). Smoking, familial history, hyperlipidemia, diabetes mellitus, renal failure, hypertension, stroke, and history of myocardial infarction was similar in two groups.
Severity of angina, urgency operation, number vessels disease, duration of cardiopulmonary bypass, duration of aortic cross clamp time, use of internal thoracic artery graft, and number of grafts was similar in both groups. Mean of bleeding post operation was 548 cc in group 1 and 803 cc in-group 2 (P=0.003). Bleeding that need to operation was 1.8% in group 1 and 8.6% in group 2 (P=0.002). Wound infection, mediastinitis, renal failure, ventilatory prolonged, stroke, need to Intra-aortic Balloon Pump (IABP), intraoperative bleeding, and hospital stay was similar in both groups. Mean of extubationt time was 10.2 hours in group 1 and 14.8 hours in group 2 (P=0.001).
Conclusion: Preoperative and intra-operative donations are safe and continue to contribute uniquely to blood conservation, providing important options in comprehensive blood conservation programs in current pediatric open-heart surgery.

Abstract
Background: This research was conducted for the purpose of determining the effect of hormonal and non-hormonal contraception on the mother milk and infants growth among lactating women received by south Tehran’s Health Centers. In this regard a broad spectrum study from December 2000 until February 2001 was done by Tehran university.
Materials and Methods: By sampling method, 200 lactating women were chosen randomly. They were divided into two groups according to their preferred method of contraception: 67 women chose hormonal method and 133 women chose non –hormonal method.
Results&Conclusion: During the time of the study on infants growth (increase in head circumstances, increase in height, increase in weight), There was no significant difference between the two groups. If we take the effect of contraceptive methods into consideration, the Triglyceride levels in non-hormonal group were increased considerably compared to the other group. Other ingredients were almost the same.

Abstract
Background: The outcome of acute hepatitis B infection may be influenced by host genetic factors like human leukocyte antigen (HLA). To investigate the association between the HLA-DRB, DQA1 and DQB1 alleles and chronic hepatitis B infection, 50 patients with chronic hepatitis B (based on 6 months positive of HBsAg and HBc antibody and HBeAg and antibody by serological test), were selected from Turkman population in north east of Iran .Allele frequency in patients were compared with a 65 aged and sex match control group from healthy blood donor of that ethnic population.
Methods: HLA DRB, DQA1 and DQB1 alleles were determined using polymerase chain reaction based on sequence specific primer (PCR-SSP) method. Allele frequencies in patients and control subjects were compared by Epi-info statistical soft-wear.
Results: There was a significant increase and positive association in HLA-DRB1*0301, DQA1*0501 and DQB1*0604 allele frequency in patients group while the frequency of HLA-DRB1*1301, 1501 and DQB1*0401 and DQA1*0401, 0102 were lower in patients than control group and shows negative association.
Conclusion: In Iranian Torkman population, HLA DRB1*0301, DQA1*0501 and DQB1*0604 have an important role in susceptibility to chronic hepatitis B infection and HLA DRB1*1301, 1501, DQB1*0401 are associated with protection to chronic hepatitis B infection. Larger case control studies may be helpful to confirm our investigation.

Abstract
Background: Hysterectomy is a common surgery as treatment for chronic and benign gynecologic problems. Eeach year more than half million women in USA undergo hysterectomy.
Methods: This analytical cross-sectional study, was done on 100 women who had underwent hysterectomy at least two years before the study and met inclusion criteria of study. During interview, the questionnaire were completed, then examination was done by gynecologist. Most of the information were collected from the patient’s files.
Results: In this study the most indication of hysterectomy was fibroma and the most common type surgery was total abdominal hysterectomy, and mostly were done without oophorectomy. 20% of cases were without or weak prior to operation and 80% with medium (or high) libido, after hysterectomy the figures changed to 41% and 59% respectively. After hysterectomy libido with P=0.001, frequency of coitus with P=0.001, and sexual satisfaction with P=0.013, significantly declined. Libido after hysterectomy declined with aging (P=0.01). There was no significant correlation between oophorectomy and libido.
Conclusion: Sexual function declines significantly after hysterectomy, with no association with oophorectomy and type of surgery.

Abstract
Background: Sepsis is the leading cause of death in critically ill patients throughout the world. The incidence is increasing despite the major advances in the development of antimicrobial agents and other supportive treatments. Based on multiple studies, it has been shown that patient outcome depends on Th1 and Th2 cytokine response. Moreover, whenever the Th2 response is predominant, the sepsis is more severe. The aim of this study was to evaluate the correlation between cytokine levels and the severity of sepsis in patients.
Methods: A cross-sectional study on the cellular levels of several pro-inflammatory cytokines was carried out in patients with sepsis and severe sepsis. The study included 37 patients (24 men and 13 women), 26 of them had sepsis and 11 had the severe form of sepsis Thirty-seven healthy volunteers served as controls. The average age of the patients was 57 years (±23.3 years), with a range of 21 to 92 years. From the whole blood of the subjects, we separated the monocytes and leukocytes, which were then cultured. Using an ELISA method, we measured levels of IFN- and IL-12 (associated with Th1), and IL-4 and IL-10 (associated with Th2) in the cultured cells with and without cell stimulation.
Results: No correlation was found for IFN- production in the cells of patients with sepsis and severe sepsis, regardless of whether the patients had died or survived. However, IL-12 levels were significantly decreased in severe sepsis compared with those of sepsis patients (P=0.048). Furthermore, the cells of expired patients also had significantly decreased IL-12 levels compared with those of surviving patients (P=0.028). We also found that the levels of IFN-, IL-4, and IL-10 were decreased in patients compared with those of controls, which correlated to their production. However, there was no correlation for IL-12 production between the cells of the patients compared with those of the controls. There was also no correlation for cytokine production between men and women with sepsis and in adults compared with that of elderly patients (>55 years old).
Conclusion: We have shown that the predominating T helper cell subset in patients with severe sepsis, as well as expired patients, is Th2. In conclusion, the correlation of Th1 cytokine production and progression of sepsis was demonstrated. Most probably IL-12 levels would be significantly lower in patients with severe sepsis and those who expired.

Abstract
Background: The presence of increased numbers of nucleated red blood cell (NRBC) in the umbilical cord blood has been associated with states of relative hypoxia. Nucleated red blood cell counts are a potentially useful tool in estimating the degree and timing of intrauterine hypoxia. This may have important implication in determining causality in case of compromised infant. Cord blood NRBC counts may be obtained noninvasively from an otherwise discarded specimen and analyzed by personnel on equipment readily available in most hospital laboratories. Since the aim of monitoring of fetal heart is early diagnosis of hypoxia, we studied the relationship between abnormal fetal heart rate with the number of nucleated red blood cells (NRBC) in the umbilical cord blood.
Methods: We performed this research at Hazrat Zeynab Hospital on 130 full-term newborns (65 cases of fetal distress and 65 normal cases) between July 2005 and July 2006. The NRBC counts of newborns with abnormal fetal heart rate were compared with those of normal newborns and correlations with other parameters including Apgar score, hemoglobin level, condition of newborns in the first 24 hours of the birth and birth weight.
Results: The mean NRBC count in the fetal distress group was 9.45 ± 8.75 and that of the normal group was 9.17 ± 8.76 per 100 white cells (p=0.89). The mean duration between diagnosis of fetal distress to birth was equal to 1.2± 0.77 hours. Furthermore, there was no meaningful correlation between number of NRBC and Apgar score, hemoglobin, birth weight and condition of newborns in the first 24 hours.
Conclusion: If the fetus is born a short time after the diagnosis of distress with no risk factors for hypoxia, the NRBC count for cord blood is not elevated.

Abstract
Background: Mitral valve prolapse is a relatively common valvular abnormality in most communities and joint hypermobility (JHM) is also seen in many healthy people as well as in certain clinical disorders, such as Marfan syndrome. The present study was designed to investigate the association between joint hypermobility and mitral valve prolapse (MVP) in an Iranian population sample.
Methods: Fifty-seven patients with nonrheumatic and isolated mitral anterior leaflet prolapse (24 men and 33 women, mean age 23.5 +/-2.3) and 51 healthy subjects (20 men and 31 women, mean age 22.9+/-2.3) were studied. The presence of JHM was evaluated according to the Carter-Wilkinson & Beighton criteria. Echocardiographic examination was performed in all subjects and the correlation between the echocardiographic features of the mitral valve and the hypermobility score were investigated.
Results: The frequency of JHM in patients with MVP was found to be significantly higher than that of controls (26.3% vs. 7.8%), with mean JHM scores of 3.1+/-2.2 and 1.9+/-1.7, respectively. The patients in the MVP group had significantly increased the anterior mitral leaflet thickness (AMLT, 3.4+/-0.4 mm vs. 3.0+/-0.3 mm p<0.0005) and maximal leaflet displacement (MLD, 2.4+/-0.3 mm vs. 1.5+/-0.2 mm p<0.0005) compared to the controls.
Conclusions: We detect a statistically significant relationship between isolated MVP and joint hypermobility as well as between the severity of JHM and echocardiographic features of the mitral leaflets. These results suggest a common etiology for MVP and JHM, which should be investigated in future well-conducted studies.

Abstract
Background: Because of importance and extensive use of textile in clinical setting especially as bandage, so outbreak of nosocomial infections due to Bacteria resistance nanobiotechnological advances in recent decade, achieved methods for fabrication antimicrobial effect in fibers that can satisfied the needs of patients in the wake of health and hygiene.
Methods: The antimicrobial effect of special type of fibers produced in Isfahan Poly Acryl Plant on one resistant strain of Pseudomonas aeruginosa isolated from 54 wound samples of patients in Isabn e Maryam hospital and P.aeruginosa (PTCC1024) was studied by using shake flask method. In order to compare the effect of pure antimicrobial agent of the fiber with that of gentamicin, the minimal inhibitory concentration of these agents was tested on strains. The effect of the interaction of these two antimicrobial agents and their fractional inhibitory concentration on chosen strains was studied using checkerboard method.
Results: The results show inefficient effect by antimicrobial fiber on P.aeruginosa strains after 24 hrs. But despite the high level MIC of gentamicin on these bacteria (1-3 µg/ml), the MIC of pure antimicrobial agent of fiber at a level of 10-3 µl/ml caused growth inhibition. The interaction of these antibacterial agents on the P.aeruginosa isolated from wound was evaluated as synergism.
Conclusions: According to this study the antimicrobial effect of the fiber on growth inhibition of P.aeruginosa strains is negative (despite of significant effect by pure antimicrobial agent used in produced the antimicrobial fiber on examined strains).

Background: Gestational diabetes mellitus is diagnosed as carbohydrate in tolerance demonstrated
for the first time in the course of pregnancy. The aim of this study was to evaluate
the selective screening method for gestational diabetes mellitus (GDM)
based on: 1- recommendation of
the fourth workshop- conference on GDM 2-
evaluation of risk factors
Methods: A case-
control study was performed on 370 pregnancies inflicted
by GDM in Hazrat
Zaynab
Hospital,
Shahed
University.
The maternal and perinatal outcomes and prevalence of risk factors based on recommendation
of the fourth workshop- conference on GDM
in these women with GDM were compared with the
same data and risk factors of randomly selected 600
pregnant women at the same time and in the same hospital, they all underwent
universal testing for GDM, and their OGTT
were normal.
Results: The prevalence of all risk factors was significantly higher in the group with GDM,
but 45 of these women (12%)
had no risk factors. 107 women (29%)
with GDM were at low risk and would remain undiagnosed
if selective screening method was used. The
main neonatal complications in the low- risk group did not differ from the
complications in other women with GDM.
Conclusions: The
universal screening of all pregnant women seems to justified whereas the
recommendations for not screening low- risk group are doubtful and require further
examination.

Background: Dietary antioxidant vitamins, in particular vitamin C,
can play a role in preventing the onset or progression of age-related visual
impairment. The aim of this study was to determine the plasma ascorbic acid
levels in normal individuals and in senile cataract patients.
Methods: The test group included fifty cataract patients, while the control group
members were selected among medical staff and patients' companions after age
matching with test group. The use questionnaire contained age, sex and location
of residency (Urban or Rural). Five milliliter of drawn blood centrifuged and
plasma ascorbic acid level was measured by spectrophotometry. Statistical
analysis of plasma ascorbic acid concentrations were done using paired t-test.
Results: The mean plasma ascorbic acid level intest group and incotral group was 0.96±0.08
and 1.12±0.15mg/dl respectively.
Plasma ascorbic acid level in test group was significantly lower than control
group (p<0.0001).
Aging was associated with a reduction in plasma ascorbic acid level in male
while it showed no significant alteration in females. Rural and the female
gender showed higher plasma ascorbic acid level.
Conclusions: This study revealed plasma ascorbic acid level in patients with senile cataract
was lower than normal individuals. Antioxidant vitamins, in particular vitamin C,
found in Mediterranean fruits and vegetables could be probably used in the
prevention of cataracts, which is a major health service burden in many
countries.

Abstract
Background: Behcet’s disease (BD) is a multisystemic inflammatory disease with unknown origin characterized by recurrent oral aphtous ulcers, genital, ocular and skin lesions. A single point mutation 1691G to A in the factor V gene increases the risk of venous thrombosis. This study designed to determine factor V Leiden mutation in Behcet’s disease, and to find out it's relationship with the clinical manifestations in Khuzestan province, Iran.
Methods: One hundred patients with Behcet's Disease (44 males and 56 females) based on international diagnostic criteria and 70 healthy subjects were included in the study.Patients and controls were tested for the presence of factor V Leiden mutation using polymerase chain reaction method.
Results: The prevalence of factor V Leiden mutation was significantly higher in BD (10 out of 100, 10%) compared with healthy control subjects (1 out of 70, 1.4%), (p=0.025).
Vascular lesions in this study were deep vein thrombosis (DVT) (7%), subcutaneous thrombophlebitis (5%), stroke (1%) and retinal vasculitis (39%). It was found that there was no association between venous thrombosis and the factor V Leiden mutation in Khuzestanian patients. Also, no association between other vascular lesions and the factor V Leiden mutation was recognized. On the other hand there was a significant association between DVT and anterior uveitis (p=0.033).
Conclusion: In this study we did not find any association between clinical manifestations in BD patients and factor V Leiden mutation in Khuzestan province, Iran
but in BD patients with DVT, factor V Leiden mutation might be a risk factor for the development of anterior uveitis.

Abstract
Background: Epidural catheters are seldom difficult to remove from patients. The breakage of the catheters is uncommon, troublesome and occasionally dangerous.
Case presentation: A lumbar epidural catheter inserted in a 17 year-old man for applying anesthesia for internal fixation of femur fracture and subsequent postoperativeepidural analgesia. In the third postoperative day, during unsuccessful attempt for removing the catheter, it was broken and was retained in his back. A CT- scan was performed and shows a fragment of catheter in the sub- laminar ligament between L3 and L4 without any connection with epidural space. As the patient had no complaint the fractured fragment was left in site and he was just followed up in the clinic.
Conclusion: The knowledge of practical method in locating the retained epidural catheter, and the indication for surgical removal are very important. CT- scan is useful in showing the mechanism and locating the epidural catheter entrapment and facilitating surgical follow-up.
