This study was designed to investigate the effect of the Clenbuterol drug in some physiological parameters of Liver, Kidney function and lipidprofie concentration. Fourty adult male rabbits were used in this study. The animals were randomly divided into four groups,the first group was given distilled water (control) ,while the other third groups were given (2,4,6 µg/kg) of Clenbuterol drug for 30 days. Blood samples were collected after 14 and 30 days of the treatment for biochemical study. Drug caused non significant increase(P<0.05)in the AST and ALT enzymeactivity in second and third groups during treatment period ,while we note a significant increase(P<0.05) in both AST,ALT enzyme level in fourth group compared with control group , as well as the occurrence of non significantly increase (P< 0.05)in the ALP enzyme level in the treated animals through treatment period .Treating with drug led to non significant decrease(P<0.05) in the uric acid and urea concentration for 14 days compared with control group,while we note significant decrease in the uric acid ,urea concentration for 30 days compared with control group.In addition the role of drug in significant decline (P<0.05)in the TC, T.G, and LDL level,while non significant decrease in the VLDL level during treatment period ,while we note significant increase in the HDL level compared with control group. Theconclusion of this study clenbuterol drug caused a significant increase in liver enzymes AST,ALT at dose 6µg/kg during treatment period with significant decrease in the uric acid,urea concentration after 30 days in addition to significant decrease in lipidprofile concentration during treatment period.
