Abstract

|
The authors have studied the distribution of alkaline phosphatase in the pharynx, esophagus, stomach (or intestinal bulb), anterior and posterior portions of intestine of three kinds of fishes. The results obtained are as follows: 1. Alkaline phosphatase activity of basal cells in the pharyngeal epithelium of loach and snakehead fish showed moderately positive reaction, and basal cells in the esophagel epithelium of loach and eel showed also moderately positive reaction. 2. Goblet cells of pharynx, esophagus, intestinal bulb and intestinal mucosa, and gastric glandular cells of the above fishes showed negative reaction for alkaline phosphatase. 3. Strongly positive reaction for alkaline phosphatase was observed at both intestinal bulb and the free border of intestinal epithelium, but weak positive reaction at the free border of posterior portion of loach intestine.
