The juxtaglomerular apparatus of rats with hereditary hypothalamic diabetes insipidus.
The juxtaglomerular apparatus (JGA) of rats with hereditary hypothalamic diabetes insipidus (DI) was studied. Plasma concentration of renin and angiotensin II, as well as serum sodium concentration and serum osmolality of DI rats are elevated. The morphological examination reveals no characteristic alteration of the epitheloid cells. The results show that the epitheloid cells are sufficiently adapted for the higher release of renin.
