Changes in Body Composition, Plasma Alanine, and Urinary Nitrogen in Rats Subjected to Negative Caloric Balance Through Diet, Diet/Exercise, and Exercise

Description: Male Fischer rats (n=43) were used in a diet-diet/ exercise design to investigate the apparent protein sparing effects of exercise. The animals were divided into five groups: INITIAL (baseline), SEDENTARY (control), DIET, DIET/EXERCISE, and EXERCISE. Carcasses were analyzed for body composition, the blood for plasma alanine concentration and the urine for urea nitrogen concentration. The results showed no significant differences between groups in urinary urea nitrogen, plasma alanine, body weig… more

Fluoride-Induced Changes in In Vivo Papillary Cyclic AMP

Description: Two separate experiments were designed to measure urinary cyclic AMP and renal papillary cyclic AMP, respectively, Results suggest that urinary cyclic AMP excretion rate is unchanged and cannot be used as an index of tubular sensitivity to either vasopressin or fluoride. However, renal papillary tissue cyclic AMP increased significantly (p<0.05) at plasma fluoride concentrations which result in polyuric renal failure. Further, it appears that fluoride independently stimulates cyclic AMP in the … more
