Bilateral renal cortical necrosis was observed after vasopressin administration in rats pretreated with oestrone acetate. Histochemical (succinic dehydrogenase, trichrome, periodic acid Schiff) and electronmicroscopic methods were used to examine how the anti-oestrogen, Tamoxifen, influences the development of this renal cortical necrosis. The experiments revealed that in most rats vasopressin did not induce renal tubular necrosis if the anti-oestrogen was administered simultaneously, even during oestrogen pretreatment. The results suggest that oestrogen receptors in the kidney are involved in the induction of renal cortical necrosis by vasopressin. |
