Sex differences in salicylic acid metabolism in streptozotocin induced diabetes in rats

Abstract

The metabolism of salicylic acid was studied in male and female streptozotocin-induced diabetic Wistar rats. Results obtained showed that in both sexes there was a significant increase in urinary excretion of salicyluric acid in diabetic rats when compared to controls (P less than or equal to 0.001). Within the diabetic groups, there was a significant increase in the urinary excretion of salicyluric acid in the female in comparison to the male rats (P less than or equal to 0.01). A statistically significant increase was observed in urinary excretion of salicyl-glucuronic acid in diabetic female compared to control female rats (P less than or equal to 0.01) while comparison of diabetic male to control male showed a significant decrease in urinary excretion of salicyl-glucuronic acid (P less than or equal to 0.01). Comparison of the diabetic female and male groups showed a high statistically significant difference in urinary excretion of salicyl-glucuronic acid. The diabetic ration, ie diabetic/control was significantly higher in female than in male rats with respect to salicyl-glucuronic acid (P less than or equal to 0.001) and total urinary excretion (P less than or equal to 0.01). The diabetic ratio may likely reflect the true significance of the roles played by the two metabolic pathways. The results suggest sex differences in the metabolism of salicylic acid; this may also be the case in other disease states.
