Renal ischemia may occur in different situations such as vascular or renal surgery and also in renal transplantation. This study evaluates renal function in dogs submitted to ischemia and reperfusion after chlorpromazine application. Twelve adult mongrel dogs were distributed into two groups with six animals each. Group A was composed of dogs submitted to renal ischemia and reperfusion without previous administration of chlorpromazine. Group B was composed of dogs with renal ischemia and reperfusion previously treated with chlorpromazine. In order to evaluate the possible ischemia/reperfusion late effects, blood and urine samples were sampled in four different times: Before ischemia, early stages of reperfusion, 120 minutes after reperfusion, and every week until 28th day postsurgery. Renal function was evaluated by clinical examination, serum urea and creatinine levels and urinary GGT activity. PU/CU and GGT urinary activity were more sensitive in detecting acute tubular injury than routine urine examination because these variables showed earlier changes. Based on urinalysis, urea and creatinine serum levels plus urinary excretion of GGT and PU/CU, no evidences of protective action of chlorpromazine were observed. |
