Abstract
Granular cell indices (GCI: Dunihue and Robertson, 1957) in kidneys of fetal rats one day after maternal nephrectomy or fetal unilateral nephrectomy on day 21 of gestation were determined by examining sections stained with Bowie's technique. Maternal nephrectomy induced an extreme increase of GCI in fetal kidneys with increased granularity of cells in the juxtaglomerular apparatus. Fetal unilateral nephrectomy did not cause any significant change.
