| Abstract: | Effect of oral administration of sodium orthovanadate for three weeks on polyol pathway in renal cortex and medulla was studied in control and alloxan diabetic rats. An enhancement in aldose reductase in cortex and medulla and sorbitol dehydrogenase in cortex was observed in alloxan diabetic rats. Despite depressed insulin secretion, vanadate treatment to diabetic rats counteracted hyperglycemia, normalized elevated enzyme activities and glucose level, prevented medullary sorbitol accumulation and markedly checked increase in kidney weight. These results show that vanadate causes marked improvement in renal hypertrophy and has an antidiabetogenic effect on polyol pathway in diabetic kidney. |
