摘　　要：为了观察贵州小型猪(Sus scrofa domestica var.mino Guizhounensis Yu.)消化道嗜银细胞的分布及形态,试验应用改良的Pascual双重银染法显示贵州小型猪消化道黏膜的嗜银细胞。结果表明:除食管外,贵州小型猪消化道各部位均有嗜银细胞的分布,主要位于固有层腺泡上皮细胞之间,黏膜上皮细胞之间很少;细胞分布密度以胃体最高,其次为贲门、胃窦,结肠最低;嗜银细胞形态以锥体形最常见,此外还可见圆形、卵圆形、梭形或不规则形等;细胞的突起可指向腺泡腔、腺泡上皮细胞或固有层的结缔组织。说明贵州小型猪胃肠黏膜内有分布广泛、形态多样的嗜银细胞,可能是贵州小型猪胃肠道强大而复杂的内分泌功能的组织学基础。To investigate the distribution and morphology of argyrophilic cells in the digestive tract of Sus Scrofa domestica var. mino guizhounen- sis Yu. A double silver staining of modified Pascual＇ methods were used to show argyrophilic ceils in the digestive tract. The results showed that there were no argyrophilic cells in esophagus, but distributing widely in the other place of digestive tract, which mainly located between alveolar epithelial cells of lamina propria, and few between mucosal epithelial cells. The distribution density of argyrophilic cells was highest in the body of stomach, followed by cardia, gastric antrum, which was lowest in colon. The shapes of argyrophilic cells were mainly cone - shaped. Besides them, the round, ellipse, shuttle and irregular coils,etc, could also be found. The cell protrusions could point to the acinar chamber, acinar epithelial cells or connective tissue of lamina propria. It is concluded that argyrophilic cells distribute widely in the gastrointestinal mucous of Sus Scrofa domestica var. mino guizhounensis Yu. The argyrophilic cells may be the histological basis for the powerful and complex endocrine function of gastrointestinal tract in Sus Scrofa domestica var. mino guizhounensis Yu.
