BIOLOGICAL PARAMETERS OF THE BLOOD IN THE GENETICALLY-OBESE ZUCKER RAT

A study of the various biological parameters of the blood in the genetically obese Zucker rat, the nonobese Zucker rat, and the Wistar rat has revealed great similarity between the two latter types of animals. On the other hand, in genetically obese Zucker rats as compared with the nonobese ones (1) the blood mass per unit of weight was lower; (2) the level of nitrogenous degradation compounds was the same; (3) the lipase activity was lower; (4) the levels of substances for which liver plays a crucial role-all lipid and protein fractions, glucose, and the enzyme GPT-were higher; (5) the levels of Ca, Zn, Fe, Cu and Pi were high; (6) the blood and bone-marrow cells were unremarkable. © 1979 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
