Background: In this study, the anti-diabetic effect of the extract of leaves and fruits of Avicennia marina (A. marina) in streptozotocin (STZ)-induced diabetic male rats was investigated. Methods: An experimental study was conducted on 45 adult male rats in 9 groups of 5 rats. The control group received normal food only. Other groups were made diabetic by injecting them with 60 mg/kg intraperitoneal STZ injection. Diabetic groups were: one Sham Group (STZ only), one Positive Diabetic Group (STZ + 0.5 ml normal saline) and 6 experimental groups, treated with STZ plus 3 incremental doses (30, 60 and 120 mg/kg) of either leaves or fruits extract of A. marina for three consecutive days, using gavage method. 24 hours after the last extract administration, blood samples were taken from the rat hearts., the serum glucose and insulin levels were measured by glucose oxidase and ELISA methods, respectively, one week after the STZ injections and following 8-12 hours of fasting. Results: The extract of leaves and fruits of A. marina in all doses significantly decreased the serum glucose in diabetic rats compared to that in the Sham group. The extract of A. marina leaves at 30 mg/kg significantly increased the serum insulin level compared to that in Diabetic Sham Group. The extract of A. marina fruits at all doses significantly increased the serum insulin level in the Experimental Groups compared to the Sham Group (P <0.05). Conclusion: The extract of leaves and fruits of A. marina significantly reduced the serum glucose in STZ-induced diabetic rats.

AbstractObjective. The vast majority of type 1 diabetes leads to a higher prevalence of reproductive system’s impairments. Troxerutin has attracted much attention owing to its favorable properties, including antihyperglycemic, anti-inflammatory, and antiapoptotic effects. This investigation was proposed to evaluate whether pretreatment with troxerutin could prevent apoptosis-induced testicular disorders in prepubertal diabetic rats.Methods. Fifty prepubertal male Wistar rats were randomly allocated into five groups: control (C), troxerutin (TX), diabetic (D), diabetic+troxerutin (DTX), and diabetic+insulin (DI). Diabetes was induced by 55 mg/kg of streptozotocin applied intraperitoneally. In TX and DTX groups, 150 mg/kg troxerutin was administered by oral gavage. Diabetic rats in DI group received 2–4 U NPH insulin subcutaneously. Troxerutin and insulin treatments were begun immediately on the day of diabetes confirmation. After 30 days, the testicular lipid peroxidation and antioxidant activity, apoptosis process, and stereology as well as serum glucose and insulin levels were assessed.Results. The results showed that diabetes caused a significant increase in the blood glucose, the number of TUNEL positive cells and tubules, and the malondialdehyde level as well as a significant decrease in serum insulin level compared to controls. The stereological analysis also revealed various alterations in diabetic rats compared to controls. Troxerutin treatment improved these alterations compared to the diabetic group.Conclusion. Troxerutin-pretreatment may play an essential role in the management of the type-1 diabetes-induced testicular disorders by decreasing blood glucose and modulating apoptosis.

Many traditional treatments have been recommended in the alternative system of medicine for diabetes mellitus. However, the mode of action of most of the herbals used has not been defined. It has been reported that sex hormones are important regulators of insulin-mediated events in skeletal muscles. In view of this, a novel herbal preparation containing antidiabetic and aphrodisiac plants was used in the present study. Adult male albino rats were divided into following groups after induction of diabetes. Rats were given an intraperitoneal (i.p.) injection of streptozotocin (STZ), at a dose of 65 mg/kg body weight after overnight fasting, to induce diabetic state with blood glucose levels >250 mg/dL. Group 1—Control rats treated with single i.p. injection of vehicle, Group 2—Rats treated with polyherbal preparation (PHP; 500 mg/kg body weight by oral intubation, morning and evening for 30 days), Group 3—STZ-diabetic rats treated orally with equal volumes of vehicle (water) alone and Group 4—STZ-diabetic rats treated with PHP after 10 days of diabetic induction. STZ-diabetes decreased the body weight, serum insulin level and glucose oxidation in liver and skeletal muscles but increased the fasting blood glucose level. After polyherbal treatment, body weight and glucose oxidation were completely restored to control level while serum insulin level was restored partially and the glucose tolerance was significantly improved. There was a significant decrease in total haemoglobin (Hb) level of diabetic rats when compared to control but polyherbal treatment significantly improved the same. However, the other parameters studied (red blood cell [RBC], white blood corpuscle [WBC], packed cell volume [PCV], mean corpuscular volume [MCV] and mean corpuscular haemoglobin [MCH]) were unaltered. In conclusion, the anti-diabetic properties of PHP appear to be mediated through pancreatic β-cell regeneration, resulting in maintenance of optimal blood glucose and its oxidation in liver and skeletal muscles.

Background: To examine the effect of Tai Chi Chuan (TCC) practice on glucose and lipid metabolism and related hormones in TCC practitioners. Methods: Twenty-one TCC practitioners and nineteen healthy controls were included in this study. Classical Yang’s TCC was practiced by the TCC practitioners. The percentage changes in serum total cholesterol (TC), high-density lipoprotein-cholesterol (HDL-C), serum glucose (SG), serum insulin, serum insulin level, homeostatic model assessment of insulin resistance (HOMA-IR), log(HOMA-IR), quantitative insulin sensitivity check index (QUICKI), and serum endothelin-1 (ET-1) before and 30 min after resting or TCC practice were compared between healthy controls and TCC practitioners. Results: Before TCC or resting, the serum insulin level, HOMA-IR, and log(HOMA-IR) of the TCC practitioners were significantly lower than those of healthy subjects, whereas the QUICKI of the TCC practitioners was significantly higher than that of healthy subjects. Thirty min after TCC practice, the %TC, %HDL-C, %QUICKI, and %ET-1 were all significantly decreased, whereas the %SG, %serum insulin, and %HOMA-IR were significantly increased in the TCC group as compared to the control group 30 min after resting. Conclusions: The serum glucose, insulin level and insulin resistance were enhanced, whereas the cholesterol, HDL-C and ET-1 levels were reduced 30 min after TCC practice. The mechanism underlying these effects of TCC 30 min after TCC is not clear yet.

The present study was carried out to evaluate antidiabetic and antihyperlipidemic effects of Dillenia indica methanolic leaves extracts in streptozotocin induced diabetic Wistar rats by administering graded oral doses (250 and 500 mg/kg body weight) for 21 days. The extract showed significant antidiabetic activity (p<0.001). Furthermore, the decreased body weight of rats was significantly improved after extract treatments. Daily oral treatment with the extract for 21 days to diabetic rats, also resulted in significant reduction in serum cholesterol, triglycerides and serum transaminase levels but HDL-cholesterol level was found to be improved (p<0.001) as compared to the diabetic control group. The extract treatment also showed to enhance serum insulin level in diabetic rats as compared to the diabetic control group. In conclusion, D. indica leaf extract might be useful for diabetes mellitus management and other abnormalities associated with this metabolic disorder.

Objectives: Type 2 diabetes is characterized by hyperglycemia and occurs as a result of insulin resistance and pancreatic beta cells failure to compensate. Present study was conducted to determine the antidiabetic effect of Withania coagulans and liraglutide on postprandial serum insulin levels and pancreatic histological features in streptozotocin induced diabetic rat. Study Design: This Randomized Control Trial. Setting: At multidisciplinary lab Islamic International Medical College, Rawalpindi in collaboration with Animal House, National Institute of Health, Islamabad. Period: From March 2016 to April 2017. Material and Methods: Forty male Sprague daily rats were randomly divided into normal Control Group A (n=10) and Experimental Group (n=30). Experimental group was given streptozotocin (30mg/kg/day) intraperitoneally for 5 days and diabetes was confirmed in experimental group by measuring fasting blood glucose level (mg/dl). Experimental group was divided further into Group B (Diabetic control), Group C (Withania coagulans treated) and Group D (Liraglutide treated). Group C were given Withania coagulans in addition to normal diet and Group D received Liraglutide besides normal diet for 30 days. Second sampling for evaluating postprandial serum insulin level and pancreatic histology was done after 30 days. Result: Postprandial serum insulin levels of Withania coagulans treated Group C (5.54 + 0.23 μU/ml) and Liraglutide treated Group D (6.06 + 0.17 μU/ml) were significantly raised in comparison with Diabetic control Group B (3.50 + 0.19 μU/ml), whereas islets of Langerhans cell morphology were markedly improved in Group C and D as compared to Group B. Conclusion: Withania coagulans significantly increases postprandial serum insulin level and improves pancreatic beta cells architecture.

ABSTRACT Cortisol implants in normal and diabetic rats reduced body weight, adiposity, insulin receptor concentration and both basal and insulin-stimulated rates of lipogenesis in isolated adipocytes, whilst insulin sensitivity was unchanged. In normal but not diabetic rats these changes were accompanied by increased serum glucose and insulin concentrations. In contrast, progesterone implants in normal and diabetic rats increased body weight gain, adiposity, insulin receptor concentration and both basal and insulin-stimulated rates of lipogenesis in adipose tissue, again without affecting insulin sensitivity. Progesterone did not affect serum insulin concentrations in normal or diabetic rats but accelerated the decline in serum glucose concentrations which occurred during an overnight fast in diabetic rats. The results suggest that (1) cortisol inhibits lipogenesis in adipose tissue without affecting insulin sensitivity, (2) cortisol reduces insulin binding in adipose tissue without a requirement for hyperinsulinaemia, which might itself indirectly lead to down-regulation of the insulin receptor, and (3) in diabetic rats progesterone stimulates lipogenesis in adipose tissue without any increase in food intake or serum insulin concentrations suggesting that progesterone may have a direct anabolic role in adipose tissue.

The insulin-resistant (IR) syndrome may be an impetus for the development of hypertension (HTN). Unfortunately, the mechanism by which this could occur is unclear. Our laboratory and others have described impaired endothelium-mediated relaxation in IR, mildly hypertensive rats. The purpose of the current study is to determine if HTN is most likely a cause or result of impaired endothelial function. Sprague-Dawley rats were randomized to receive a fructose-rich diet for 3, 7, 10, 14, 18, or 28 days or were placed in a control group. The control group received rat chow. After diet treatment, animals were instrumented with arterial cannulas, and while awake and unrestrained, their blood pressure (BP) was measured. Subsequently, endothelium-mediated relaxation to acetylcholine was determined (in vitro) by measuring intraluminal diameter of phenylephrine-preconstricted mesenteric arteries (∼250 μM). Serum insulin levels were significantly elevated in all groups receiving fructose feeding compared with control, whereas there were no differences in serum glucose levels between groups. Impairment of endothelium-mediated relaxation starts by day 14 [mean percent maximal relaxation (Emax): 69 ± 10% of baseline] and becomes significant by day 18 (Emax: 52 ± 11% of baseline; P < 0.01). However, the mean BP (mmHg) does not become significantly elevated until day 28 [BP: 132 ± 1 ( day 28) vs. 116 ± 3 (control); P < 0.05]. These findings demonstrate that both IR and endothelial dysfunction occur before HTN in this model and suggest that endothelial dysfunction may be a mechanism linking insulin resistance and essential HTN.
