为了评价动物的免疫状态,可以通过检查免疫系统中的T和B淋巴细胞群的方法。现有的一些检查方法(如花环形成、免疫荧光、细胞毒试验等)都非常繁杂。况且,在分离淋巴细胞的过程中会出现选择性的丢失细胞(主要是T淋巴细胞,Singh等,1974),特异性抗血清制备的操作又需要一定的实际经验,即使这样,其活性也未必保持完全一致。研究者们特别注意了鉴定淋巴细胞的改 In order to evaluate the animal’s immune status, it is possible to examine the T and B lymphocyte population in the immune system. Some of the existing inspection methods (such as rosette formation, immunofluorescence, cytotoxicity test, etc.) are very complicated. Moreover, selective loss of cells during the isolation of lymphocytes (mainly T lymphocytes, Singh et al., 1974) requires some practical experience in the preparation of specific antisera, even though their activity may not Keep exactly the same. Researchers have paid special attention to the identification of lymphocytes
