  The objective of this study was to investigate whether pre freezing and post thawing (motility, morphology, viability, acrosome integrity and membrane integrity). Boer goat spermatozoa are affected by collecting in an Tris citric acid fructose extender supplemented with hypotaurine or cysteine. Semen was collected from four bucks into tubes containing 0 mL extender (Contro I), 2 mL extender without supplementation of antioxidants (Control II), 2 mL extender supplemented with hypotaurine 10 mM and 2 mL extender with cysteine 5 mm. No significant (p>0.05) improvement was observed by adding extender into collection tubes either supplemented or not with antioxidants before freezing and after freeze thawing. While a slight improvement was observed in motility, membrane integrity and acrosome integrity when 2 mL Tris citric acid fructose extender supplemented with either hypotaurine or cysteine. In conclusion, addition of extender in collection tubes either supplemented or not with antioxidants is not beneficial for Boer goat semen cryopreservation.

  This study is performed to investigate the bacterial contamination of the water resources and the pipeline networks of the city. Faecal coliforms (such as Escherichia coli (E. coli) as the most important indicator of water contamination), non-faecal coliforms and Pseudomonas aeruginosa (which have recently been introduced as a new indicator of water contamination) as well as the number of phototrophic bacteria are examined. Samples collected from all wells, a big reservoir supplying big part of the city’s water (called Khordad 15 Dam), main pipeline networks, settling and resting reservoirs and finally treated water consumed by people under a sterile condition. The results showed 25% of samples from main water resources of Qom city were contaminated with confirm but no contamination detected in treated water. 16.7% of were samples were contaminated with Pseudomonas aeruginosa after subculturing to Acetamid broth, but 11.8% of treated water samples confirmed to be contaminated with this bacterium in the second subculture. Although the results of this study demonstrated the potential threats of bacterial contamination (such as coliforms) in water resources, Qom’s fresh water is safe and water treatment facilities there work quietly efficient and remove all coliform contaminations. The appearance of Pseudomonas aeruginosa contamination in drinking water is a sign of pipeline network cracks and erosions which require new efforts to repair and renew them.

  Recent studies have shown that certain man-made compounds (including some pesticides and herbicide) through interfering with endocrine system, have the capability to induce developmental and reproductive abnormalities in humans and animals. Pesticides are currently being used in large scales in many developed and developing countries (including Iran), so this study has been conducted to determine the percentage of endocrine disruptor agents in pesticides used in Fars province. The results showed that more than 1,581,690 L of pesticides, in 86 different brands, have been used in Fars province during year 1380 and 25.93% (34 types) of them had at least one carcinogenic agents. At least 30 pesticides (711720 L, 44.99%) had one endocrine disruptor agent and therefore can be classified as environmental hormones or endocrine disrupting chemicals. The percentage of pesticides whom interfering with normal endocrine system activity were, 7.82% (66572 L), 4.54% (39975 L), 22.02% (348400 L), 5.12% (81000 L) and 21.18% (34500 L) of pesticides were antiestrogenic, antiandorgenic, antityroidic, antigonadotropin and anitestroid hormones, respectively. The results showed that about 50% of pesticides which currently being used in Fars province should be banned.

  Screening and preventive programs are critical components in reduction of breast cancer morbidity and mortality.A cross-section self-administered questionnaire survey was conducted to explore the knowledge and practices of breast cancer prevention modalities among a large descendant of the Iranian traditional female society. We have collected 400 questionnaires per stratum and 2400 totally. The mean age of the respondents was 25.01 years (SD = 8.78) with a range of 15-78, 46.9% were married, 86.7% had a medium-high educational level, 23.5% were housewives, 54.2% were students and family history of breast cancer was reported by 25.8%. Knowledge about breast cancer prevention was 28.5% accep, 67.3% low and 4.2% poor in the study population. 37% of the women 20 to 40 years and 48.8% of the women older than 40 years performed Breast Self-Examination (BSE) but only 17.1% did it monthly. Approximately 13.12% felt very confident that they could examine their own breasts correctly. 82.6% of the women 20 years and older never underwent a specialist visit. Among women 40 years of age and older, approximately 65.86% underwent a specialist visit once and 47.3% had obtained mammograms in the last 2 years and 61.07% have had at least one mammograms until now.The Iranian female population needs planning health education interventions and population-based specific regular screening programs to improve cancer prevention.

  Sodium Warfarin is one of the oral anti coagulant drugs that is used by some patients to avoid thromboemboli. For these patients one of the problems after the surgery is hemorrhage. These patients should be checked and evaluated before the surgery. The aim of this study, was to determine and compare the effect of interruption, adjusting and continuing warfarin on bleeding after tooth extraction. In an experimental study, we surveyed the effect of warfarin on bleeding for 17 patients with 81 extractions. On the basis of the received results from lab and the amount of Pro-Thrombin time (PT), The kind of problem and consulting with cardiovascular specialist on interruption, adjusting and continuing the use of drug were decided 0.37 extractions in group one (continuing the drug), 33 extractions in group 2 (drug adjustment) and 11 extractions in group 3 (discontinuing the use of the drug). All the patients underwent a bilateral symmetrical extraction of the teeth. The findings were analyzed by correlation coefficient, chi-square (χ2) and t-tests. The average amount of INR was 2.25 ± 0.55 in all 3 groups (SD = 0.55). The results showed average amount of PT in patients with no bleeding was 19.7±2.3, while in mild bleeding it was 19.3±4.7. In 3 groups no hemorrhage was observed after extraction in the first 30 min. During the first 24 h, only 8 of the extractions, who did not notice the post operative orders, showed signs of mild bleeding. The difference between group 1 and the other groups was not significant statistic cally (p>0.5). There was no hemorrhage in the 3 groups 48 h and 5 days after extraction. There was no significant relationship between hemorrhage and the type of systemic disease either clinically or statistically. It was concluded that continuing Warfarin if International Normalized Ratio (INR) is in the Normal Range (INR<4) poses no danger for the patient and if the patient is at risk of thrombo-emboli, continuing the drug is advised. In cases of INR>4 adjusting the drug should be taken into consideration. It is not advised to stop the medication if the consequences are irreparable.
