Diabetogenic action of streptozotocin: relationship of dose to metabolic response.

The relationship between the dose of intravenously administered streptozotocin (a N-nitroso derivative of glucosamine) and the diabetogenic response has been explored by use of the following indices of diabetogenic action: serum glucose, urine volume, and glycosuria, ketonuria, serum immunoreactive insulin (IRI), and pancreatic IRI content. Diabetogenic activity could be demonstrated between th...

Effect of L-carnitine on diabetogenic action of streptozotocin in rats.

OBJECTIVES L-carnitine is a naturally compound widely distributed in the body. It has an antiradical effect and decreases lipid peroxidation. In acute or chronic streptozotocin (STZ)-induced diabetic rats, the pancreatic content of carnitine was found to be significantly lower than nondiabetic group. We investigated the effects of L-carnitine on the development of STZ-induced diabetes in rats, ...

Short-term insulin treatment prevents the diabetogenic action of streptozotocin in rats.

Streptozotocin, which induces diabetes mellitus in experimental animals, has been reported to be taken up by beta-cells by means of the glucose transporter 2 (GLUT2) and then reduce the cellular level of NAD+, leading to necrosis of the beta-cells. We investigated the effect of insulin pretreatment on the diabetogenic action of streptozotocin (60 mg/kg). Four groups of rats were studied: 1) a g...

Diabetogenic Action of Alloxan on Liver Histopathology

The cytotoxic alloxan is the most prominent diabetogenic chemical agent in experimental diabetes research. Alloxan has been found to be selectively toxic to liver hepatocytes. The experiments aim to understand the effect of alloxan on cytomorphology of liver in rat. Treatment with alloxan caused central vein congestion with significant dilatation of sinusoidal spaces. The liver of the alloxan t...

Elevated white blood cell counts and risk of metabolic syndrome: a dose-response meta-analysis

Background and Aim: Elevated white blood cell count has been a known risk factor for cardiovascular diseases. Cardiometabolic diseases have some risk factors in common. Therefore, we assessed the association between elevated white blood cell counts and risk of metabolic syndrome using dose-response meta-analysis method. Materials & Methods: We searched for observational studies including white ...
