The lymphocytes of the rat thymus can be grossly differentiated by their cell membrane-bound proteinases. Subcapsular thymocytes lack aminopeptidase A (APA) and AMP and gamma-glutamyltranspeptidase (GGT). Cortical thymocytes show a high activity of APA but no APM and no GGT. Medullar thymocytes possess a high GGT and APM activity but are free of APA. Under Mg deficiency, the APA-negative subcapsular thymocytes are reduced. In lymphoma and beginning lymphoma, APA, APM and GGT are absent. In lymphoma, the alkaline phosphatase activity is increased. Differences are found for dipeptidylpeptidase IV (DPP IV). In some lymphoma, its activity is reduced, in others the DPP IV activity is increased.
大鼠胸腺中的淋巴细胞可通过其细胞膜结合蛋白酶进行大致区分。被膜下胸腺细胞缺乏氨肽酶A（APA）、AMP和γ-谷氨酰转肽酶（GGT）。皮质胸腺细胞显示出高活性的APA，但没有APM和GGT。髓质胸腺细胞具有高活性的GGT和APM，但没有APA。在镁缺乏的情况下，APA阴性的被膜下胸腺细胞会减少。在淋巴瘤和早期淋巴瘤中，不存在APA、APM和GGT。在淋巴瘤中，碱性磷酸酶活性增加。二肽基肽酶IV（DPP IV）存在差异。在一些淋巴瘤中，其活性降低，而在另一些淋巴瘤中，DPP IV活性增加。
