diabetes mellitus is the most common cause of chronic renal disorders and end-stage kidney disease in developed countries. it is the major cause of dialysis and transplantation. failure in renal function causes wide disorders in the body. diabetes results in wide range of alterations in the renal tissue. it is believed that early histological changes in diabetic nephropathy are detectable 2 yea...

background: quercetin is a strong antioxidant and long-term treatment of stz-diabetic animals and it has been shown to reduce oxidative stress.   objective: antioxidants have essential effect on spermatogenesis and sperm parameters. enhanced oxidative stress and changes in antioxidant capacity are considered to play an important role in the pathogenesis of chronic diabetes mellitus.   methods: ...

In the rat isolated perfused kidney, arachidonic acid elicits cyclooxygenase-dependent vasoconstriction through activation of PGH2/TxA2 receptors; responses are enhanced in kidneys from diabetic rats. This study examined the roles of cyclooxygenase-1/cyclooxygenase-2 in the enhanced renal vasoconstrictor effect of arachidonic acid in streptozotocin-diabetic rats. Release of 20-HETE was also det...

diabetes mellitus is accompanied with disturbances in learning, memory, and cognitive skills in the human society and experimental animals. therefore, this research study was conducted to evaluate time-dependent changes in passive avoidance and y-maze performance in male diabetic rats. for this purpose, male wistar rats were randomly divided into control and diabetic groups. for induction of di...

The Spontaneously Diabetic Torii (SDT) fatty rat, established by introducing the fa allele of the Zucker fatty rat into the SDT rat genome, is a new model of obese type 2 diabetes. The SDT-fa/fa (SDT fatty) rat shows overt obesity, and hyperglycemia and hyperlipidemia are observed at a young age as compared with the SDT-+/+ (SDT normal) rat. However, the features of the diabetic complications i...

objective: diabetes is a metabolic disorder which impairs carbohydrate and lipid metabolism. it is accompanied by cognition impairment in diabetic patients and animal models. lipids play an important role in nerve membrane composition, structure and function. this study was designed to evaluate the effect of dietary butter and sesame oils on passive avoidance memory of streptozotocin (stz) diab...

To determine whether the effects of fatty acids on the diabetic heart during ischemia involve altered glycolytic ATP and proton production, we measured energetics and intracellular pH (pH(i)) by using (31)P NMR spectroscopy plus [2-(3)H]glucose uptake in isolated rat hearts. Hearts from 7-wk streptozotocin diabetic and control rats, perfused with buffer containing 11 mM glucose, with or without...

conclusions troxerutin may reduce the vascular complications and tissue injuries induced by chronic diabetes in rat aorta through increasing the activity of tissue antioxidant system and reducing the level of lipid peroxidation. materials and methods male wistar rats were randomly divided into four groups (n = 8/each): control, control plus troxerutin, diabetic and diabetic plus troxerutin. dia...
