The localization of hydrochloric acid in the gastric glands of Ophycephalus punctatus and Heteropneustes fossilis has been examined histochemically. The fishes were force-fed with the Prussian blue reagents in a test meal and the distribution of the precipitate was examined at regular intervals. Maximum amount of precipitate was observed in the lumen and at the mouth of the openings of the gastric glands 12 h after feeding in Ophiocephalus and at 18 h in Heteropneustes. Pepsinogen granules were distributed in all the cells lining the gastric glands. No histochemical difference was observed in the cells lining the gastric glands, and all the cells were capable of producing both HC1 and pepsinogen.
用组织化学方法研究了斑鳢和印度鲇胃腺中盐酸的定位。给鱼强制喂食含普鲁士蓝试剂的试验餐，并定期检查沉淀物的分布。喂食后12小时，在斑鳢的胃腺腔和开口处观察到最大量的沉淀物；在印度鲇中则在18小时观察到。胃蛋白酶原颗粒分布在胃腺内衬的所有细胞中。在胃腺内衬细胞中未观察到组织化学差异，所有细胞都能产生盐酸和胃蛋白酶原。
