چکیده

Kidney and liver mitochondria of rat, rabbit and guinea pig are able to transform 3-hydroxy-3-methylglutarate into acetoacetate, whereas ox liver mitochondria and rat mitochondria of heart, diaphragm and brain do not exhibit such an activity. Starvation and streptozotocin treatment decreases the formation of acetoacetate from 3-hydroxy-3-methylglutarate. Addition of acetoacetate and succinate to the incubation media of mitochondria results in a decrease in the transformation of 3-hydroxy-3-methylglutarate into acetoacetate. A 3-hydroxy-3-methylglutaryl-CoA hydrolase is present in rat liver mitochondria; the activity does not show appreciable changes after starvation or streptozotocin treatment.

Oral Supplementation of ?-Carotene Significantly Ameliorates Testicular Oxidative Stress in the Streptozotocin-Diabetic Rat

Background Our recent findings have shown that the rat testis is subjected to significant oxidative stress during the early phase of diabetes induced by Streptozotocin (STZ). In the present study, we have investigated whether oral supplementation of β-carotene (BC) to pubertal rats would provide protection against diabetes associated oxidative stress in testis and liver.

Effect of Helicteres isora Bark Extract on Protein Metabolism and Marker Enzymes in Streptozotocin-Induced Diabetic Rats

The present study investigated the possible protective effect of Helicteres isora (Sterculiaceae) bark extracts on certain biochemical markers in streptozotocin (STZ)-induced diabetes in rats. STZ treatment (60 mg/kg/i.p) caused a hyperglycemic state that led to various physiological and biochemical alterations. Blood levels of glucose, urea, uric acid and creatinine, plasma levels of albumin a...
