THE ELECTRON ENZYME HISTOCHEMICAL STUDY ON LYMPH NODE AROUND CANCER TISSUE IN PATIENTS WITH MALIGNANT TUMOR
Cai Yuwen, et al (Dept. of Histology and Embryology)
In this paper, we have studied ATPase, G-6-Pase in lymphocytes at paracortical region in lymph node around cancer tissue in patients with malignant tumor by use of elecron enzyme histochemical method. The result shows that the activity of above-mentioned enzymes has been weakened, their granules became tinier and the number is decreased, their density is lower. This suggests that the decrease of the enzyme activity may Le the main reason leading to the decrease of cellular immunological function in these patients.
