Introduction: The exact places of mast cells in human testicular tissue remains unclear. This study was conducted to show places of mast cell accumulation and relation between number of mast cell and infertility in non- obstructive azoospermia patients. Materials & Methods: 12 biopsies from the testis tissues of non obstructive azoospermia patients referred to Royan institue (patient group) and 5 biopsies from persons with prostatic cancer (control group) were used in this study. Light and electron microscopic studies were performed on processed tissues. 1% toluidine blue staining were used for counting the number of mast cells.Results: Thickening of lamina properia and basement membrane of seminiferous tubule and fibrosis in interstitial tissue was observed in patient group. The total number of mast cells in patients group were significantly increased in comparison to control group.Conclusion: Results of this study revealed fibrosis in interstitial and peritubular tissues of patient group. Observed fibrotic changes in testicular tissues of patient group resulted from the increased number of mast cells.

Introduction: Diabetes mellitus is the most important metabolic disorder and its prevalence is increasing. There are contradictory reports about the cardiovascular side effects of sulfonylureas which are used for treating diabetes mellitus. The objective of this study was to observe the vascular effects of Glibenclamide, a second generation of sulfonylurea in rats. Material & Methods: Male rats were injected intraperitonealy in a dose of 5mg/kg body weight for one month. Animals were killed at the end of study and the response of isolated aortic rings to phenylephrine; Acetylcholine and Isosorbide dinitrate was studied. Results: There was no significant difference between the responses of aortic rings of treated and control rats to acetylcholine, Isosorbide dinitrate and phenyl ephrine Conclusion: Intraperitoneal injection of 5mg/kg body weight glibenclamide for one month did not make any changes in the contractile properties of isolated aortic rings. Since glibenclamide acts through closing ATP dependent potassium channels and closing these channels during myocardial Ischemia in patients with coronary artery disease can bring major problems. Further studies are needed to make sure that glibenclamide do not change the contractile properties of vascular smooth muscles.

Introduction: The most important health problem with antibiotic consumption in poultry is the presence of antimicrobial residues in poultry products consumed by humans. Consuming poultry products with antibiotic residues is like the direct use of antibiotics. Material and Methods: This study was conducted to evaluate the residues of antibacterial substances in one hundred poultry carcases of Sanandaj slaughterhouse during four consecutive seasons. Samples were collected from liver, muscles of breast, wing and thigh and tested with four plate test which is a qualitative method for antibiotic residual detection. For this purpose Bacillus subtilis & Micrococcus luteus were cultured in Mueller Hinton Agar with the PH of 6, 7.2 and 8. Results: Results showed that 72 (72%) of 100 carcases had antibiotic residues at one or more sites which is higher than maximum residue limit. 44(60.91%) had residue in one organ, 11(15.5%) in two organs, 8(11.09%) in three organs and 9 (12.5%) in four organs. Liver was the most common site of antibiotic residue (51%) followed by breast (35%) wing (21%) and thigh (19%). Contamination was more common in winter (80%) and less common in autumn (60%). Conclusion: The rate of contamination in studied samples was high (72%) and should be considered as a priority in public health.

Introduction: Luteal phase defect (LPD) is a hormonal disorder of reproductive system, and an abnormal ovarian function. It is presented by recurrent abortion and infertility. Stressful environmental factors such as stressful job situations and moderate or severe exercise are associated with luteal phase defect. This study was performed to evaluate the relation between luteal phase defect and endurance exercise in runner women. Material & Methods: Statistical population included 150 non-athletic and athletic runners women aged between 20-30 years with regular menstrual cycle without lactation who had not taken hormonal tablets recently. By checking luteinizing hormone level and serial sonography ovulation time was detected. 15 runners who obtained excellent grade in Bruce test were selected as study group and compared with 15 height, weight and age-matched non athletic women. Serum progesterone was checked at the 21st day of cycle by Elisa test and those with serum progesterone less than 10ngr/ml considered as LPD. Result: The result of this study showed significant association between LPD and running. Serum progesterone levels were decreased by exercise. Conclusion: Regarding the result of this study moderate to severe exercise are responsible for increasing the incidence of LPD in athletic women.

Introduction: Intramedullary pinning with round pin as a method for fixing ulnar shaft fractures results in 20% non union. In this study we compared intramedullary fixation method with round pin and post operative splinting method . Materials & Methods: 62 patients with ulna fractures referred to Imam khomeini and Razi hospitals of Ahwaz from 2001 to 2003 were divided randomly into two equal groups. First group were treated by intramedullary pinning and control group with plating. Radius fracture was fixed with plate if accompanied by ulna fracture. In the first group a long posterior splint was used after operation for 6 weeks. Motions of elbow and wrist started whithin 3 weeks. In the second group splinting was done for one week and motions of the elbow and wrist begun whithin a week. Patients were followed up at intervals of 2,6,12 and 24 weeks after surgery. Nnonunion, malunion and the rate of wrist and elbow motions were compared in two groups. Results: nonunion, malunion , wrist stiffness and elbow stiffness in treated and control groups was 6.45%, 3.22%, 6.45%, 0% and 3.22%,0%,3.22%, 0% respectively. 75.8% of patients were male. Etiology of the fx was 72.5% indirect force and 27.5% direct force. The rate of associated injury of Radius fx with ulnar fx was 59.6% . The mean age of patients was 26.9 years. Conclusion: There was no significant difference between the result of treatment in two groups. Intramedulary fixation with round pin and postoperative splinting is an cheap and easy method that can be used instead of plating.

Introduction: Improper pakaging, personnels and instruments are the major sources of nutrient contamination. Contamination can be decreased by screening food handlers through physical exam and laboratory tests. The aim of this study was determining the quality of exams performed by sanandaj central laboratory to certify the health of food handlers. Material and Methods: This study was descriptive and studeid population included 447 food handlers refered to sanandaj central laboratory to obtain health certificate. Stool exam results compared between central and reference laboratories. Collected data was analyzed using diescriptive statistics. Results: 54 of the examined persons was illiterate. There was significant difference between those who diagnosed with intestinal parasite infection in central (6.9%) and reference (28.5%) laboratories. The age of 50% of persons with parasite infection was between 20-29. The job of 38.7% was bakery. The most commone intestinal parasites detected were giardia and ascaris Conclusion: Since the aim of the screening laboratory tests is screening infected persons and with respect to the low sensitivity of the exam results (14%) in sanandaj central laboratory, regular monitoring of central laboratory are recommended

Introduction: Stress because of its somatic and psychotic health effects has been changed to a challenge in the management of organizations. Choosing of nursing as a career is full of stress which can compromise the quality of services delivered by nurses. This study was done to evaluate the amount and source of stress in nurses working in intensive care units of Kurdistan University of medical sciences. Material and Methods: This study was descriptive-analytic and the population under study included 70 nurses working in special wards which were selected by simple random sampling. Data was collected by a questionnaire contained 41 questions in 4 parts. Results: Statistical analysis of the data showed that approximately all nurses in special wards experienced some degree of psychosomatic and environmental stress. The most important source of stress among soma tics was lack of rest which accounted for 35% of somatic stressors. 55.71% of psychotic stress was related to the environment of the ward. In peripheral units 38.57% of stressors were due to the field infectious diseases. Conclusion: Further evaluation and consideration of stress, stressors and the sources of stress is recommended. These findings also suggest that stress prevention and reduction methods are of significant importance for the managers of medical centers.
