Monitoramento da indução do diabetes mellitus em ratos wistar com aloxana em diferentes doses

Abstract

The aim of this study was to monitor the induction of experimental diabetes mellitus in female Wistar rats by intraperitoneal administration of alloxan in different doses and dose to assess which provides the highest incidence of diabetes with lower death rates. Four experimental groups of 30 animals each as follows: control group (CG) received intraperitoneal (ip) solution of sodium chloride 0.9% and group G80, G120 and G200, received via (ip) diluted in 2% alloxan solution physiological doses of 80, 120 and 200mg/kg respectively. We evaluated blood glucose, temperature, weight, water intake, food intake and percentage of deaths at different times. It is concluded that all doses of alloxan administered intraperitoneally after 24 hours of fasting were able to induce diabetes mellitus and monitoring of temperature, glucose and dehydration of the animals during the first week, was paramount to the success of induction, and 120mg/kg dose of the most effective in achieving greater number of diabetic animals and lower incidence of deaths.
