Background & Objective: Iodine deficiency is one of the most important life-threatening factors from the beginning and encounter irreversible damage to human. This study aimed to investigate stability of Iodine in iodized salt in different situations such as light and humidity and comparing it with standard amounts.
Methods: In this cross-sectional descriptive-analytical study, 12 samples of iodized salts which have been distributed in Damghan, were accidentally selected. Samples were examined in the chemistry laboratory of Faculty of Health (Damghan University of Medical Sciences) using titration method recommended by British pharmacopeh. 10 mg of each iodized salts were kept at presence of light, darkness, humidity, and non- humidity situation and then titration method was performed. The samples were kept for two weeks and examined weekly. Data were analyzed with T paired and ANOVA tests using SPSS software.
Results: Findings of this study showed that reduction of Iodine was seen for all samples. The amount of reduction were 2.2, 1.5, 4.1 and 2.1 mg/l for purified salts at light, darkness, humidity, and non- humidity situation, respectively. The amount of reduction were 3.4, 2.1, 5.35 and 2.6 mg/l for non-purified salts at light, darkness, humidity, and non- humidity situation, respectively. In spite of reduction in Iodine, concentration of it was at standard amount (30-50 PPM).
Conclusion: Results showed that stability of iodine was more when salt was exposed to darkness in comparison with light situation (p< 0.09). Meanwhile, the stability of purified salts was more than the non- purified salts (p< 0.28). Also, stability of iodine was less at humidity in comparison with non- humid situation (p< 0.006). The purified salts which was exposed to humidity was much stable compared to the non- purified salts (p< 0.28). It also, demonstrated that the amount of iodine stability was more for salts which was exposed to light in comparison with humidity (p< 0.05).

Background & Objectives: Diabetes mellitus is a metabolic disease characterized by hyperglycemia together with biochemical alterations of lipid profile, insulin resistance and inflammation . Considering the high prevalence of hypertension, dyslipidemia and inflammation in type 2 diabetic patients, the aim of the present study was to investigate the effects of inulin on lipid profile, inflammation and blood pressure in women with type 2 diabetes.
Methods: In this controlled, randomized clinical trial, 49 women with type 2 diabetes (fiber intake<30 g/d, BMI=25-35 kg/m2) were assigned to one of two groups. Experimental group (n=24) received 10 g/d inulin and control group (n=25) received 10 g/d maltodextrin for 8 weeks. Dietary intakes, anthropometric measurements, blood pressure, serum lipids and hs-CRP concentrations were measured at the baseline and at the end of the study. Data were analyzed using SPSS software (verision11.5). Paired, independent t-tests and ANCOVA were used to compare quantitative variables.
Results: At the end of study, there was a significant decrease in systolic blood pressure (from 135.7 ± 16.2 to 125.9 ± 7.9 mmHg), total cholesterol ( from 192.5 ± 42.8 to 171.0 ± 39.7 mg/dl), triglyceride ( from 223.3 ± 84.2 to 169.9 ± 65.6 mg/dl) and hs-CRP ( from 7.9 ± 3.0 to 5.3 ± 3.0 mg/l) in inulin group compared with the maltodextrin group (p > 0.04 ). Changes in diastolic blood pressures, LDL-c and HDL-c were not significant in inulin group compared with the maltodextrin group. A significant decrease in systolic, diastolic blood pressures, total cholesterol, triglyceride, LDL-c, hs-CRP and significant increase in HDL-c were observed in inulin group compared to baseline.
Conclusions: Inulin supplementation may improve lipid profile, hs-CRP and blood pressure in women with type 2 diabetes.

Background & objectives : Infertility is a global problem affecting millions of men and women in developed and developing countries. In this regard, in-vitro fertilization (IVF) plays an important role in improving the quality of life in infertile patients. However, studies have shown that the implantation failure in IVF is the main challenge of this procedure. Melatonin can increase the survival rate of embryos and IVF success rate through eliminating free radicals and removing reactive oxygen species. So, this study is conducted to investigate the effects of different concentrations of melatonin on the rate of newborns of mice following transfer oftwo-cell embryos .
Methods : In this study, female mice with average age of six to eight weeks were superovulated by administering pregnant mares serum gonadotropin (PMSG) intraperitoneally (7.5 IU. ip), and followed after 48h by human chorionic gonadotropin (hCG) (7.5 IU. ip). Two-cell mouse embryos were obtained from female mice oviduct after 48 h. The embryos transferred bilaterally into pseudopregnant mice of the same strain through surgical procedure and 8-14 embryos were transferred to each tube. The study included 4 treatment groups and one control group (6 mice in each group). The treatment groups were exposed to subcutaneous injection of concentrations of 100 µm , 10 µm , 1 µm and 100 nm of melatonin. After the cesarean on 18th day of pregnancy, the percentage of live births was assessed. The outcomes of the live birth rate were assessed using the chi-square test and statistical analyses were carried out using SPSS version 16.0. Percentage of live birth was calculated and compared with the control group.
Results: A total of 701 two-cell mouse embryos were transferred into one control group and four experimental groups. The number and percentage of live births at concentrations of 100 µm and 10 µm of melatonin and the control groups were 21 (15.55%), 13 (9.15%) and 9 (6.47%), respectively. No infant was born at the concentrations of 1 µM and 100 nM of melatonin . The highest rate of live births was obtained at the concentration of 100 µM and showed a significant difference with the control group (p ≤ 0.01). There was no significant difference in live births at the concentration of 10 µm and control group.
Conclusion : The results of this study indicated that subcutaneous injection of melatonin improves the two-cell mouse embryo growth and post implantation development of mice.
