Histological influences of low-dose-morphlne hydrochlorur on rat kidneys

İn this study the effects of low-dose morphine hydrochlorur on rat kidney vvere determined at light microscopical level. A total of 30 Sprague Davvley rats from both sexes (15 male and 15 female) vvere used. Five rats from both sexes vvere served as Controls, vvhereas 10 rats from each sex vvere used as experimental group. Control animals vvere injected subcutaneously vvith physiological şaline (5mg/kg), the animals of experimental group vvere given morphine hydrochlorur at a dose of 5 mg/kg in every other day. At the end of the experiment, the animals vvere perfused vvith buffered formaline (pH=7.4) under anaesthesia, and kidneys vvere extirpated, and morphometrical measurements (thickness, height, length) vvere taken. Follovving, kidney samples vvere processed by means of routine histological techniques and the sections vvere taken at 7pm thickness, and stained. Slides vvere then examined using light microscope. The investigations have revealed that the low-dose-morphine hydrochlorur caused to glomerular destruction, epithelial necrosis and desquamation in both proximal and distal tubuli, vascular hyperemia and hemorrhagies. Based on the findings, it was concluded that the results of this study might be specific to the rat kidney vvhich is devoid of detoxification enzymes in tubuler epithelial cells and a study should be performed on an animal having similar metabolism with human.
