Acute kidney disturbances by lead acetate in the rat.

Four groups of 5 male and 5 female rats were dosed i.p. with 0, 0.05, 0.15 and 0.30 mmol Pb2+/kg as neutral acetate. A minimal kidney damage shown by an increased urinary GGt was only observed in males at the highest dose. In all animals and for all doses natriuria was significantly decreased on the first day (from the 4th hour). Such disturbances evoke mild tubular disturbances but glomerular disturbances may also be involved.
