Modifications in Bowie's Staining of pepsinogen granules

Modifications of Bowie's technic for staining the pepsinogen granules of the body chief cells in the gastric glands, and a method of preparing the stomach of small rodents (e.g. the rat) for histo-topographical studies are described. The modifications involve counter-staining with aqueous alum hematoxylin, the use of the neutral synthetic mounting medium Permount, and changes in the timing of fixation, staining and differentiation.
