Female Sex Hormone and Nephropathy in Cohen Diabetic Rat (Genetically Selected Sucrose-Fed)

Summary

In the Cohen diabetic rat (genetically-selected sucrose-fed) ovariectomy resulted in a significantly decreased incidence of nephropathy, while estradiol treatment to the ovariectomized animal increased the rate of nephropathy to the levels occurring in the uncastrated untreated diabetic female. In the male diabetic animal orchidectomy caused a slight decrease in the rate of nephropathy whereas estradiol treatment to the orchidectomized animal resulted in a slight increase in the rate. No difference was found between the ovariectomized and the uncastrated diabetic female as to the spontaneous blood glucose, plasma insulin, serum cholesterol or TG levels, but a significant difference was found in their plasma estradiol levels.
