Furthermore, anthropometric indices such as body mass index (BMI), waist circumference and waist-to-hip ratio (WHR) can independently and sometimes more severely lead to BP changes. The objective of this study was to assess BP status and its relationship with anthropometric indices among women in rural areas of Kerman province, Iran. Materials and Methods: This cross-sectional study was performed on 370 women of reproductive age (20-45 years old). General information were gathered from each sample using questionnaire and face-to-face interview. Body weight, height, waist and hip circumferences were measured and BMI and WHR were calculated for each subject. Data were analyzed using one-way analysis of variance (ANOVA), independent t-test and Pearson’s correlation coefficient tests. Results: 15.9% and 22.8% of subjects were obese and abdominal obese (WHR>0.8) respectively. 14.3% of subjects were also hypertensive. BP significantly increased with weight, BMI, WHR, waist circumference and number of pregnancy. Furthermore, BMI was positively associated with systolic blood pressure (SBP) and diastolic blood pressure (DBP) (r =0.26, p<0. 002 and r =0.32, p<0.0001 respectively).There was also a positive correlation between WHR with SBP (r =0.22, p<0.003) and DBP (r =0.24, p<0.002). In addition, waist circumference was positively correlated with DBP (r =0.18, p<0.05). Conclusion: Anthropometric indices have positive and significant correlation with blood pressure changes in women of reproductive age. It is generally recommended to consider weight control and body fitness for hypertension prevention in women.

Abstract
Background : Noise is a kind of environmental pollution affecting the life of humans. Many researches have been carried out on the effects of noise stress on the different parts of body, but few studies have been done on sexual systems. The aim of this study is to investigate the effects of noise stress on testosterone, LH and FSH.
Materials and Methods: Two groups of ten male rats have been introduced to 2 noisy environments of experimental and ordinary (with intensity of 90-120 decibel and frequency of 300-350 HZ) for fifty days from 7 am to 7 pm. After 50 days blood samples were collected from tail and level of testosterone, LH and FSH measured by Eliza and results were interpreted using T test with a significance of p<0.05.
Results: Statistical studies showed that the average of testosterone secretion, LH and FSH in comparison with control group, had a significant difference (p<0.05).
Conclusion: On the whole it can be said that sonic stresses decrease the level of testosterone, LH and FSH.

Abstract
Background : Ischemia-reperfusion injury arising from testicular torsion can result in bilateral testicular damages. The aim of this study was to investigate the effect of doxycycline (DC) administration on epididymal sperm disorders following experimental unilateral testicular ischemia-reperfusion (IR) in mice.
Materials and Methods: Experiments were performed on five equal groups each comprising six adult male mice. Following anaesthesia, IR was induced by clamping left testicular vessels with an atraumatic microvascular clamp for 30 minutes in IR group. In IR+DC group, in addition, mice received DC (2.5 mg/kg per day) intraperitoneally for 3 days starting from the day of induction of experimental IR. Vehicle-treated control group, sham-operated control group and DC-only treated group were also included. Ipsilateral and contralateral epididymal sperm characteristics were evaluated after 35 days.
Results: Ischemia-reperfusion caused significant decreases in the both epididymides sperms concentration, viability and motility compared to the control group. Moreover, sperm cell apoptosis in both the ischemic and the contralateral epididymides and the percentage of sperm abnormality in ipsilateral epididymis increased significantly after IR. Doxycycline treatment attenuated all IR-induced negative changes in the above-noted parameters.
Conclusion: These findings provide evidence that DC treatment may have potentially protective effects against long-term reproductive injuries following unilateral testicular IR.
