title: Enzyme histochemical and histological changes in the adult rat kidney after prenatal gentamicin exposure.
abstract: Treatment of rats between day 15 and 20 of gestation with gentamicin caused histological as well as enzyme histochemical lesions in the kidney of the one year old offspring (F1 generation). Other organs were not significantly affected. Primarily in the female kidney dilated convoluted proximal tubulus with reduced or absent staining for brush border and lysosomal proteases, phosphatases and glycosidases and mitochondrial dehydrogenases were observed. In comparison, glomeruli were less frequently damaged and contained fewer capillary loops or irregularly arranged tissue elements with lowered or no activities for plasma membrane-associated proteases as well as specific and non-specific phosphatases. In addition, the activities of proteases and phosphatases in cortical and medullary endothelial cells of capillaries were reduced or even abolished in the kidney of the female and male F1 generation after treatment of their mothers with gentamicin.
