Purpose: To verify if rat kidneys lesioned by ischaemia followed by reperfusion are affected by cyclosporine A (CsA).
Methods: Male Wistar rats were randomly divided into three groups, control (GS) and experimental (G1 and G2). G1 was subdivided in two: G1A composed of animals submitted to 60 minutes ischaemia and G1C with the same ischaemic procedure associated to 20 mg/kg/day CsA.
