Background and Aim: Type 1 diabetes has been considered among of the metabolic diseases in various societies. Some research indicated that exercise and supplementation could have positive effects on the treatment of various diseases. The purpose of this study was to investigate the interactive effect of exercises and nettle consumption on the amount of apelin as an adipokine secreted from adipose tissue in rats with type1 diabetes mellitus. Materials and Methods: For this purpose, 40 male Wistar rats were randomly divided into four groups: control, nettle, resistance training+nettle, and endurance training+nettle groups. Using streptozotocin, type 1 diabetes was induced in all animals. All groups-except control group- received 1 mg/kg body weight daily of nettle extract. The "resistance training+nettle" group climbed a ladder with weights attached to the tail that gradually increased. Also, "endurance training+nettle" group practiced swimming. Training protocols were performed for eight weeks, and at the end of the eighth weeks, blood samples were taken directly from the left ventricle of the heart. Plasma apelin measurement was performed using the apelin laboratory kit by ELISA. Dependent t-test for determine weight changes; one-way ANOVA and Tukey's test for compare averages and Pearson correlation coefficient for the relationship between variables were used for statistical analysis and the significance level was set as pResults: Apelin showed significant increase in "nettle" (p=0.04), "resistance training+nettle" (p=0.04), and "endurance training+nettle" groups compared to the control group (p=0.0001). Changes in this index in "endurance training+nettle" group were more significant than "nettle" (p=0.02) and "resistance training+nettle" (p=0.04) groups. A significant decrease was observed in "control," "nettle," and "resistance training+nettle" groups (p=0.0001) for the weight of animals between pre and post-test, but it was not significant in "endurance training+nettle" group (p=0.89). Conclusion: Lack of weight losing and improvement in plasma apelin levels in "endurance training+nettle" group in rats with type1 diabetes is probably due to the interactive effect of endurance training with the simultaneous of the nettle consumption.

Background and Aim: Aerobic endurance training is the most efficient type of physical training. It indicate beneficial effects on obese subjects because of decreasing chronic inflammation. Apelin plays a key role in energy metabolism adjustment. Therefore it is important to study the levels of blood apelin in obese people. The aim of this study was to investigate the effects of 12 weeks of progressive aerobic training on the level of apelin, TNF-α, IL-6 and CRP in obese inactive women. Materials and Methods: In this semi-experimental study, 30 obese inactive women (mean age 37.19±1.75 yr, body mass index 35.01±2.42 kg/m2) with no regular physical training were selected. They were randomly divided into two groups (N=15) including training and control groups. The individuals in the training group performed a progressive aerobic training protocol including running 3 days a week during period of 12 weeks up to the 60 to 80 percent of maximum heart rate. The average of exercise duration in every session was approximately 60 minutes. Fasting blood samples were taken before and after protocol. The concentrations of biochemical markers in plasma and serum were measured by commercial ELISA kits. To extraction of results the two-way ANOVA 2×2 test was applied and the significance level was considered as p≤0.05. Results: Two-way ANOVA was demonstrated the significant decreases in levels of apelin (p<0.001), TNF-α (p<0.001), IL-6 (p<0.001) and CRP (p<0.001) after progressive aerobic training. Conclusion: Progressive aerobic training is related to reduction of fat tissue and cytokines production and consequently decreases in apelin levels. The apelin reduction can be considered as a well-known mechanism to decrease inflammation in obese inactive women.

Background and Aim: Cardiac rehabilitation is a new approach in various ways to increase performance and efficiency of patient. This study examined the effect of 12 weeks of endurance training with testosterone injections on Chemerin and Apelin levels in the process of rehabilitation in male adult rats with ischemic heart disease. Materials and Methods: 40 Wistar male rats (average weight 200 ± 10 g and 8 weeks old) were randomly divided into four groups (n=10) and stored in a controlled environment : 1) control group (C), 2) injection of testosterone propionate group ( TP), 3) endurance training group (ET) and 4) Endurance Training with injections of testosterone Propionate (ETTP) . Endurance training group exercised for 12 weeks (5 days/week) and testosterone propionate group were given Testosterone propionate injections (3 times/week). Isoproterenol (50 mg/kg) was dissolved in normal saline and was injected intraperitoneally (i.p.) during two days within 24 hours in order to create empirical myocardial infarction. After 12 weeks, rats anesthetized with sodium thiopental (50 mg/kg) and blood samples were taken and chemerin and apelin levels were measured by using ELISA method and data analysis was done using one-way ANOVA and post-hoc LSD tests. Results: The results revealed a significant reduction in the amount Chemerin in endurance training (p=0.008), injected testosterone (p=0.03) and endurance training with testosterone injections (p=0.01) knows shown and the significant increase significant amounts of apelin in endurance training (p=0.001), injected testosterone (p=0.001) and endurance training with testosterone injections (p=0.001) was observed. Conclusion: This study shows that injection of testosterone and endurance training in the process of rehabilitation is feasible and can have a positive effect on cardiovascular health.
