肥大细胞是机体组织器官中一种重要的细胞成分,含有丰富的酶系和多种生物活性物质.肥大细胞作用广泛,参与机体的免疫调节,与过敏反应、肿瘤发生等亦有密切关系.不同组织器官中的肥大细胞具有不同的功能,因此研究肥大细胞的生物学特性具有重要的理论意义和广泛的应用价值.常规 HE 染色不能辨别肥大细胞,需用特殊染色方法显示.笔者同时应用 3 种特殊染色方法对大鼠胸腺、脾和淋巴结内的肥大细胞染色结果进行了比较.

With FAAS, contents of three trace elements, Zn, Cu and Fe in the extract of fetus brain were detected, and then compared with the same kind of preparations for analysis. The content of Zn (g·L×10 -3 ) was 0.237±0.052 while they were respectively 0.083±0.011 and 0.305± 0.042 for Cu and Fe. The contents of Zn and Cu were higher than those of the other 4 kinds of preparations, and the content of Fe was in the second place. It is suggested that the clinical effect of the extract of fetus brain is better than that of other 4 preparations.
