In this study, against streptozotocin (STZ) induced diapetic nephropathy (DN); it is aimed to investigate the use of thymoquinone (TQ) and β-aminoisobutyric acid (BAIBA) compare effects these agents. With randomselection 35 male rats, five groups (seven rats in each group) were constituted as follows: Control, STZ, STZ + TQ, BAIBA, TQ BAIBA. group; body weight, glutathione (GSH) insulin levels ...

introduction: liver plays a pivotal role in glucose and lipid homeostasis. this study was undertaken to evaluate the effects of l. acanthodes hydro-alcoholic extract administration on the liver functional and histological parameters in hyperglycemic rats. methods: twenty-four male wistar rats were randomly allocated into four groups control, hyperglycemic (stz), hyperglycemic + insulin (stz+ins...

The levels of serum ACE activity unchanged 3 days post STZ treatment but it was significantly an increase 12 and 30 days post STZ treatment in diabetic rats (p<0.001). Lung ACE activity was significantly incerased at 12 and 30 days post STZ Treatment in diabetic rats (P<0.05 and P<0.005). There was not showed an increase in the liver ACE activity at 3 and 12 days in diabetic rats such it was si...

The aim of the present study was the evaluation of possible protective effects of exercise against beta-cell damage in streptozotocin (STZ)-induced diabetes in rats. The animals were divided into five groups: the control group, the STZ-induced diabetes group, the STZ-induced diabetes and light-intensity exercise group, the STZ-induced diabetes and moderate-intensity exercise group, and the STZ-...

We investigated the role of prostaglandins in the renal vascular response to exogenous and endogenous adenosine in control and streptozotocin (STZ) diabetic rats. Exogenous adenosine (0.01-100 nmol) injected into the abdominal aorta decreased renal blood flow (RBF) in a dose-dependent manner to a much greater extent in STZ rats than in control rats ( P < 0.001). Inhibition of prostaglandin synt...

BACKGROUND In spite of a large amount of studies in anesthetized animals, isolated hearts, and in vitro cardiomyocytes, to our knowledge, myocardial function was never studied in conscious diabetic rats. Myocardial performance and the response to stress caused by dobutamine were examined in conscious rats, fifteen days after the onset of diabetes caused by streptozotocin (STZ). The protective e...

First published November 27, 2007; doi:10.1152/ajpendo.00296.2007.—In wild-type mice, a single injection of streptozotocin (STZ, 200 mg/kg body wt...

The present study compared the progression of renal injury in Sprague-Dawley (SD) and Dahl salt-sensitive (SS) treated with streptozotocin (STZ). The rats received an injection of STZ (50 mg/kg ip) and an insulin pellet (2 U/day sc) to maintain the blood glucose levels between 400 and 600 mg/dl. Twelve weeks later, arterial pressure (143 ± 6 vs. 107 ± 8 mmHg) and proteinuria (557 ± 85 vs. 81 ± ...

The aim of the present work was to test the sensitivity of young male Wistar rats, Dobrá Voda (Dv:WI) to the diabetogenic effect of streptozotocin (STZ) with regard to their health condition and mortality rates. Eight-week-old rats, weighing from 200 to 230 g, were randomised into five groups of eight animals. Streptozotocin was administered by i.v. injection in doses of 40, 50, 60 and 70 mg/kg...
