Simultaneous Specific Demonstration of Thyrotroph, Gonadotroph and Acidophil Cells in the Anterior Hypophysis

Abstract

A staining sequence for the simultaneous demonstration of thyrotrophs, gonadotrophs, and acidophils in the anterior hypophysis is described. It consists of permanganate oxidation, aldehyde-thionin, luxol fast blue, periodate oxidation and leuco fuchsin. By this technique rat and dog pituitaries fixed in mercuric chloride-formalin show blue-black thyrotrophs, red gonadotrophs, green acidophils and unstained or faintly stained chromophobes.
