在PASM染色的睾丸组织切片中,我们发现睾丸间质内一些细胞的颗粒能被六胺银很好的显示,并且特异性很好,只显示该种细胞的颗粒,而间质内的其它细胞均不着色。从组织学推测,睾丸间质内有颗粒的细胞只有肥大细胞,其它细胞内均无颗粒。为了证实这一推测,对大鼠的肠系膜铺片进行肥大 In PASM-stained testicular tissue sections, we found that some of the cells in the testis interstitium could be well-displayed by hexamine silver and have good specificity, showing only the particles of the cell type, while other cells in the interstitium No coloring. Histologically speculated that there is only granulosa cells within the testicular interstitium mast cells, no other cells within the particle. To confirm this conjecture, hypertrophy was performed on rat mesenteric patches
