Increasing the levels of blood lipids is the most common factors in diabetes that will exacerbate its complications. PJ (Pomegranate juice) is a nutrient with medical purposes. The present study aimed to investigate the effects of pomegranate juice on levels of triglycerides, cholesterol; LDL and HDL in healthy and diabetic adult male rats were done. In the study, 90 adult male rats weighing 220-200 g were divided into groups of control, diabetic and non-diabetic experimental groups. Each group includes 9 mice. Experimental groups received respectively 1, 2 and 4 ml of pomegranate juice per rat for 21 days. To create diabetes by Intra-peritoneal injection, streptozotocin 60mg/kg was used. At the end of experiment by the phlebotomizing the animal hearts, serum levels of triglycerides, cholesterol, LDL and HDL were measured. Data were analyzed by ANOVA and LSD tests.

Diabetes is one of the most common chronic diseases with a high prevalence that increases with age. It is predicted that by 2030, more than 360 million people in the world will have diabetes. The present study aimed to investigate the effect of intermittent and continuous training on leptin receptor expression in brain tissue and food intake in aged rats. This basic and experimental research was conducted on 32 female Sprague-Dawley rats. The rats were randomly divided into four groups: healthy control, diabetic control, intermittent training, and continuous training, with each group consisting of 8 samples. The training protocols involved were tailored to test the specific impact of different exercise regimens. The intermittent training group underwent a regime of high-intensity interval training, while the continuous training group engaged in steady-state, moderate-intensity exercise. The control groups did not participate in any structured physical activity. Following the training period, leptin levels and food intake were meticulously measured. Leptin gene expression in the brain tissue was assessed using Real-Time PCR, a highly sensitive and specific method for quantifying gene expression. Food intake was monitored and recorded at the beginning and end of the study period. The results demonstrated a statistically significant increase in leptin gene expression in the brain tissue of the rats subjected to intermittent training (P=0.001). This suggests that intermittent training may more effectively stimulate molecular pathways associated with leptin receptor expression compared to continuous training. Furthermore, a significant difference in food intake was observed between the groups after the eight-week training period (P=0.001). Tukey’s post hoc analysis revealed a significant difference between the high-intensity interval training and continuous training groups in terms of leptin expression (P=0.03), indicating that the type and intensity of training can differentially influence leptin receptor dynamics. Additionally, food intake in the diabetic control group was significantly higher compared to the training groups (P=0.001), suggesting that physical activity can mitigate hyperphagia in diabetic conditions. However, both interval and continuous training exerted a similar effect on overall food intake (P=0.58), implying that while the type of exercise influences leptin expression, the regulation of food consumption might be governed by other compensatory mechanisms. In conclusion, the findings underscore the significant impact of intermittent training on leptin gene expression in brain tissue of aged rats, highlighting its potential advantages over continuous training in modulating molecular markers linked to energy homeostasis. Nonetheless, both training modalities exhibited comparable effects on food intake, emphasizing the complexity of exercise-induced metabolic regulation.

Diabetes and liver diseases are serious problems and threaten the health of communities. Nettle has been introduced in traditional Iranian medicine as a blood glucose lowering drug. There are conflicting scientific reports about the effects of reducing the blood sugar of nettle, but this plant has good antioxidant and anti-inflammatory properties to reduce liver damage. Current study, examines the anti-diabetic and liver protective effects of the aqueous extract of urtica dioica in vistar male rats. The mice were divided into five groups and in order to investigation of anti-diabetic and liver protective effects, test groups obtained daily 2.5 and 5 ml/kg of the aqueous extract of urtica dioica orally for 14 and 32 days, respectively. Blood glucose was measured with a glucometer and liver enzyme activity was measured with ParsAzmoon kits. The results were analyzed using Student's T–Test and ANOVA using SPSS software version 21. Blood sugar levels in first and second test groups (170 and 122 mg/dl) showed a significant decrease compared to the negative control group (446 mg/dl). The activity of liver enzymes in the first and second test groups also showed a significant decrease compared to the negative control group. The aqueous extract of urtica dioica has beneficial effects in managing diabetes and maintaining the health of liver cells against toxic compounds.

Diabetes mellitus is a metabolic disorder that is created by hyperglycemia and impaired insulin secretion, resistance to insulin action or both. Researches show that aqueous extracts of white tea has an antioxidant properties but few studies have been conducted on the effects of diabetic and hyperlipidemic. The aim of this study was to evaluate the effect of aqueous extract of white tea on the lipid profile and blood glucose in streptozotocin-induced diabetic rats. In the experimental study, 32 male Wistar rats were randomly divided into 4 groups of 8 were; First group, control group that received standard diet and a daily 1ml of distilled water via gavage; the second group, streptozotocin-induced diabetic rats; the third group, healthy rats aqueous extract of white tea (1.5 percent) were consumed; the forth group, diabetic rats that were consumed aqueous extracts of white tea (1.5 percent). After the treatment period (30 days) to determine blood glucose levels and lipid profile was performed and the data were analyzed with SPSS software (P<0.05). A significant decreases in serum levels of glucose, LDL, cholesterol and triglyceride and significant increase in levels of HDL and weight were observed in the group receiving aqueous extract of white tea (P<0.05). The results showed that aqueous extracts of white tea decreases serum levels of glucose, triglycerides, total cholesterol, LDL and HDL cholesterol levels significantly (P<0.05). The aqueous extracts of white tea is effective for hyperglycemia and hyperlipidemia in diabetic rats.

Recent reports have shown that some Plant Isoflavones have beneficial effects on diabetes and liver health in human and laboratory animals. The aim of this study was to administrate of hydroalcoholic extract of Trifolium pretense (red clover) as a plant rich in Isoflavones compounds and its effects on serum levels of glucose and liver enzymes (AST, ALT and ALP) in mice. In this experimental study, 42 male mice were divided into 6 groups of 7, including healthy control, diabetic without treatment (positive control), diabetic treated with glibenclamide groups, and three diabetic groups treated respectively with 250, 500 and 750 mg/kg of hydroalcoholic extract of red clover by gavage for 15 days. Diabetes was induced by intraperitoneal injection of streptozotocin, 60 mg/kg. On the last day, serum glucose and Liver Enzymes (ALT, ALP and AST) levels were measured. The data were analyzed by SPSS statistical software and OneWay ANOVA test. The significant was shown with (P<0.05).Doses of 500 mg/kg and 750 mg/kg of extract were significantly (P<0.001) decreased serum glucose compared with positive control group. Assessment of liver enzymes shown that AST level in 750mg/kg group (P<0.001), ALT level in 500 mg/kg (P<0.01) and 750 mg/kg (P<0.001) groups, and ALP level in 250 mg/kg (P<0.05), 500 mg/kg (P<0.001) and 750 mg/kg (P<0.001) groups significantly decreased compared with positive control group. It seems that the red clover has anti-diabetic and hepatoprotectiveeffects.

A cardiovascular problem is one of the common complications of diabetes. Connexin is the predominant protein subunit in gap junction structure which is important in communication between cells. Considering the role of connexin, this question can be created in the mind whether changes in phosphorylated connexin 43 occurs in diabetics thoracic aorta or not? 20 male Wistar rats (30050g) were randomly divided into two groups (n=10): control and diabetic group. Diabetes mellitus was induced by intraperitoneal injection of streptozotocin (60 mg/Kg). After 60-days, rats were anaesthetized and then thoracic aorta was isolated and immediately Freeze, at the end phosphorylated connexin 43 levels were measured by ELISA method. In this study, a significant increase in the level of connexin 43 is observed in the diabetic group (P
