[Activity of tissue cathepsin-L-like proteinases of women with womb body oncopathology].

Activity and optimal pH of cathepsin-L-like proteinases was studied in benign and malignant tumours of the womb body. In the benign tumors activity of cathepsin-L-like proteinases changes depending on the expansion and depth of extension benign tumour and is defined by proliferative potential of tumour cells of myometrium and endometrium. Activity of cathepsin-L-like proteinases in malignant epithelial tumour of endometrium--adenocarcinoma is inversely proportional to the level of differentiation of the tumour cells.
