EFFECT OF STANOZOLOL ON BODY-COMPOSITION, NITROGEN-BALANCE, AND FOOD-CONSUMPTION IN CASTRATED DOGS WITH CHRONIC-RENAL-FAILURE

Objective - To determine the effect of stanozolol on body composition, nitrogen balance, and food consumption in castrated dogs with chronic renal failure. Design - Blinded crossover trial. Animals - 22 castrat ed Beagles with experimentally induced chronic renal failure. Procedur e - Dogs were divided into 2 groups of 11 dogs each. During each of tw o 6-week treatment periods, dogs in 1 group received stanozolol, and t hose in the other group received a control agent. Nitrogen balance, bo dy composition, and food consumption were determined. Results - During administration of stanozolol, the amount of food consumed per dog, le an body mass, and nitrogen balance increased. Stanozolol did not have a significant effect on body fat, bone mineral content, or food consum ption per kilogram of body weight. Clinical Implications - For dogs wi th mild-to-moderate, nonuremic, experimentally induced, chronic renal failure, stanozolol had positive effects on nitrogen balance and lean body mass.
