摘要

本實驗目的是進行產蛋來亨雞消化管道之組織構造，及其碳酸酐醋（carbonic anhydrase; CA）分佈之研究。實驗結果，碳酸酐酶廣泛分佈於消化管道之上皮，腺體之主細胞，與及肌胃之非角化複層上皮細胞。本研究顯示食道、腺胃肌胃及十二指腸之上皮層；另外，其活性也存在於內皮細胞及紅血球。然而，腺胃之胃腺明顯地沒有璧細胞（parietal cell）存在。本研究認為雞之腺胃體之主細胞，是一種產酸酶原細胞（oxyntopeptic cell）形式，同時具有酶原顆粒與胃酸之分泌功能。

The purpose of this study was to investigate the micro anatomical structure of the digestive tracts, and the distribution of carbonic anhydrase (CA) of digestive tracts in the laying chickens (Leghorn). It has been reported that CA was found widespread in the epithelial cell, especially in chief cell of proventriculum and non-keratinized stratified squation epithelial cells, as well as gland of ventriculum. The results of this study indicated the expression of CA activity was noted in the epithelium of esophagus, proventriculum, ventriculum and duodenum. Likewise, the endothelial cells and erythrocytes in all examined samples have shown CA activities. However, no parietal cells in the gastric glandular cell of proventriculum was noted in this study, suggesting that the chief (oxynpeptic cells) may have functions concerning both the zymogen granule and the hydrogen chloride secretion.
