用龙桂开银浸法，对蛤蚧小肠的嗜银，亲银细胞的分布及形态学作了初步观察，结果如下：１）蛤蚧小肠的嗜银、亲银细胞的密度，在小肠上段（相当于十二指肠）最高，由中段（相当于空肠）到下段（相当于回肠）逐渐减少．２）在粘膜上皮的嗜银、亲银细胞密度较高，而肠腺则较稀少．３）嗜银、亲银细胞在肠腺基底部着色较浅，在腺体上部着色加深，在绒毛顶端为深染．嗜银、亲银细胞基底部有突起，穿过基膜到达固有层．嗜银颗粒到达细胞顶端较为多见，有时可见嗜银颗粒释放到腺腔内．４）在小肠固有层的结缔组织内，发现有嗜银、亲银细胞，细胞充满嗜银颗粒，有时可见嗜银颗粒到达细胞外．颗粒的形态，致密度及染色特点．与上皮细胞之间的嗜银细胞相同．
Using Longgui Kaiyin’s silver immersion method, the distribution of argyrophilic silver cells and the morphology of the pro-silver cells were observed. The results were as follows: 1) The density of silver-philinating and pro-silver cells in the small intestine of the small intestine was relatively high in the small intestine (equivalent The highest in the duodenum, from the middle (equivalent to the jejunum) to the lower segment (equivalent to the ileum) is gradually reduced. 2) In the mucosal epithelium, the density of silver-philing, pro-silver cells is high, while the intestinal glands are scarce. 3) The argyrophilic and pro-silver cells stained shallowly in the basement of the intestinal glands and deepened in the upper part of the glands, and were deeply stained at the top of the villi. 2. The basal part of silver-philing and pro-silver cells has protrusions that reach the intrinsic layer through the basement membrane. Silver granules reach the top of the cell is more common, and sometimes seen in the erythrocyte granules released into the glandular cavity. 4) In the connective tissue of the small intestine intrinsic layer, argyrophilic and pro-silver cells are found. The cells are filled with erythrophilic granules, and sometimes the argil particles reach the extracellular space. Particle morphology, density and dyeing characteristics. It is the same as the argent cells between epithelial cells.
