病理标本是形态教学和科研的重要材料、也是肿瘤诊断的重要依据,而组织固定是制作诊断切片的关键,因此寻找一种理想的病理大体标本固定液是病理诊断中的重要环节。目前常用的大体标本固定液为10%福尔马林液。我科自1991年9月—10月采用20%中性缓冲福尔马林液固定大体标本54例,效果理想,总结如下。 Pathological specimens are important materials for morphological teaching and scientific research, as well as an important basis for tumor diagnosis, and tissue fixation is the key to making diagnostic sections. Therefore, finding an ideal pathological gross specimen fixed fluid is an important part of pathological diagnosis. At present, the general sample fixative is 10% formalin. In our department, from September to October 1991, 54 specimens were fixed with 20% neutral buffered formalin solution. The results were satisfactory and summarized as follows.
