[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.

[Problem of classifying malignant lymphomas].

The classification of malignant lymphomas (ML) after Rappaport is characterized by precise criteria and contributes to a mutual understanding of morphologists and clinicians. The detection of a nonspecific esterase activity facilitates the identification of ML cell elements, since the enzyme activity is insignificant in lymphocytes and intensive in histiocytes. Moreover, the method facilitates to diagnose nodular forms of ML since it aids in revealing the compression of lymph node stroma with tumor foci.
