    摘要:

    运用Grimelius银染法对菲牛蛭(Poecilobdella manillensis)消化管内嗜银细胞的分布和形态进行观察,并根据嗜银细胞的分布特点统计其分布密度。消化管除食道外各部位均有嗜银细胞分布,细胞染棕色或黑色;嗜银细胞基本位于上皮细胞之间和固有层内,主要呈圆形、椭圆形、锥体形和长条形等多种形态;部分细胞胞突明显,细胞内可见黑色分泌颗粒。嗜银细胞分布密度为颚片最高,嗉囊次之,直肠最低,食道内未检测出嗜银细胞。消化管各段嗜银细胞的形态特征和分布规律可能与其食性和消化生理活动密切相关。

    Abstract:

    Grimelius' silver nitrate stain was used to investigate the morphology and distribution of argyrophilic cells in digestive tube of the Mexican Medical Leech (Poecilobdella manillensis). The distribution density of argyrophilic cells was counted according to the distribution characteristics. All the measured data were compared with Duncan multiple comparison using spss 17.0. The level of significant difference was set at P < 0.05. The results showed that argyrophilic cells did not exist in esophagus (PlateⅠ: 5), but distributed throughout most of the other portions in different densities (PlateⅠ). These cells were stained with brownish or black in the digestive tube. Argyrophilic cells in epithelium of lips had apophysis pointing to the oral cavity, and some of them had distinct cytoplasmic processes and inner cell visible black particles (PlateⅠ: 1). Argyrophilic cells were observed in the jaw, with shapes of circle, ellipse, strip and so on (PlateⅠ: 2, 3). Most argyrophilic cells in epithelium of crop and villus epithelium of intestine had apophysis pointing to the crop or intestine (PlateⅠ6﹣8), while a minority stretched their processes to the lamina porpria (PlateⅠ: 9), indicating the possible luminal secretion and endocrine functions of these cells. The density of argyrophilic cells in the jaw was the highest (117.63 ± 14.08), while that in the rectum was the lowest (2.63 ± 0.91). There was extremely significant difference between the two parts (P < 0.05). No argyrophilic cells were also observed in the esophagus (Table 1). Based on these results, we inferred that the morphology and distribution of argyrophilic cells in the digestive tube might be closely related to the feeding and digestive physiological activities of this leech.
