Sialoprotein is one of the most abundant non-collageneous and phosphorylated glycoproteins in human. This protein plays an important role in the structure of human teeth. The aim of this project is to measure the amount of dentin Sialoprotein in the healthy and decay teeth to evaluate the variation in the teeth structure. In this investigation 50 decay teeth has been collected from patients referred to the clinic. The dentin was separated and placed in liquid Nitrogen. One gram of each dentin was washed with distilled water for 30 mins and subsequently the dentin was powdered, and relocated to the gaunidin-Hcl tris buffer, and incubated at 4°C for 48 hrs. The dentin powder was centrifuged at 3000 g for 20 mine. The supernatant was discarded, and the samples again was centrifuged at 10000 g. Finally one ml of this supernatant transferred to the sepharose column and washed with gaunidin-Hcl tris at 1 ml/min. The fractions obtained by chromatography was monitored by electrophoresis. The amount of decay teeth Sialoprotein was 17.23±1.45 ng/l and in the healthy teeth was 26.39±4.27 ng/l. The results from this study indicate that the Sialoprotein content in patient dentin decreased by about 1.5 time compared normal subjects.

Background&Objective: Primary dysmenorrhea is one of the common causes of absence from work place and life quality among women. According to some studies, fish oil administration results in production of weaker prostaglandin’s (PG) and reduces the severity of dysmenorrhea. The aim of this study is to experience the efficacy of fish oil on dysmenorrhea, which is a cheap drug and with low side effects. Materials&Methods: In this clinical trial, the students separated into two groups those affected with primary dysmenorrhea by referring to girls' high schools and complete the questionnaires. In the next stage randomly were selected two groups each group included 22 students with primary dysmenorrhea. In first group fish oil capsules and the other group placebo were recommended for duration of two months. These students were evaluated before drug recommendation, at the end of two months treatment and two months afterward. In these three stages pain severity by VAS (Visual Analogue Scale) system and pain duration by Cox scaling system were be recorded in each group. Results: There is not meaningfull statistically difference in the average age, age of menarche, menstrual condition (regular or irregular) and accompaniment with symptoms of PMS (premenstrual syndrome) between fish oil and placebo groups. Before recommendation of capsules the average of pain severity did not have a meaningful statistically difference between two groups. The average pain duration also had similar situation. After two months treatment, the average of pain severity (VAS) in fish oil group was significantly less than which in placebo group (p<0.05). Also the average of pain duration in fish oil group was less than which in placebo group with a statistical difference of (p<0.05). Moreover, two months after the end of treatment the average of pain severity (VAS) and pain duration (hour) had meaningfull statistically difference between fish oil and placebo groups and were less in fish oil group. Conclusion: As compared with placebo, the fish oil capsule after two months of consumption had a significant effect on reduction of pain severity and duration in primary dismenorrhea. Also two months afterward from the end of this clinical trial the effect was more than placebo.

Background and Objective: Alpha lipoic acid (ALA) is a powerful biological antioxidant which is involved in metabolism and energy production as a co-factor in mitochondrial dehydrogenase enzyme complex. This study was done to evaluate the effect of aerobic exercise and alpha lipoic acid supplement on insulin resistance in females with type 2 diabetes. Methods: In this quasi-experimental study, 44 females with type 2 diabetes divided into four groups including: control, supplementation, training and supplementation + training groups. Patients of supplementation and complex (supplementation + training) groups took three 100mg ALA capsules per day for eight weeks. The training program consisted of 8 weeks and three sessions per week. In each session, the subjects warmed up for 10-15 minutes, ran on a treadmill with the intensity of 40-50% of maximum heart rate for 30 minutes and then cooled down for 5-10 minutes. Blood samples were taken after 12-14 hours fasting in two stages - the beginning and the end of the eighth week. Results: Eight weeks of taking ALA supplements significantly reduced patients' insulin resistance (P<0.05). Eight weeks of running on a treadmill with an intensity of 40-50% of maximum heart rate non-significantly reduced insulin resistance in the training group compared to the controls. In the supplementation + training group a significant reduction of insulin resistance was observed (P<0.05). Conclusion: Alpha lipoic acid supplementation reduces insulin and insulin resistance. While, reduction in fasting blood glucose level causes reduction in insulin resistance in the combination of supplementation and training.
