[Nonspecific esterase activity in malignant non-lymphogranulomatous lymphomas]

It is recommended to determine the activity of nonspecific esterase in malignant non-lymphogranulomatous lymphomas (MNL) and to use for this purpose 5-bromindoxylacetate with poststaining of sections with aluminous carmine. In lymph nodes, affected with MNL, this procedure facilitates the detection of the arrangement of reticular cells and the degree of MNL penetration with hystiocytes. Also such structural features of MNL as their follicular structure and infiltration of sinuses of lymph nodes with the tumor tissue are determined.
