title: Comparative hormonal profile of two newly developed obese congenic rat strains.
abstract: 1. The effect of feeding diets containing either 54% sucrose or cooked corn starch for 12 weeks on levels of fasting plasma insulin, corticosterone, growth hormone and glucagon were compared in two newly developed genetically obese rat strains--the normoglycemic LA/N-cp and the diabetic SHR/N-cp. 2. In corpulent rats of either strain, levels of plasma insulin and corticosterone were greater when compared to the lean littermates. Corpulent LA/N-cp rats had lower levels of plasma glucagon and higher levels of plasma growth hormone than did lean LA/N-cp rats. 3. SHR/N-cp rats fed sucrose had greater levels of corticosterone and glucagon than did SHR/N-cp rats fed starch.
