[Beta-glucuronidase activity and the cellular ultrastructure of the lymph nodes in malignant non-Hodgkin lymphomas]

Lymphoid elements from lymph nodes of malignant non-Hodgkin's lymphomas were studied by the methods of beta-glucuronidase cytochemistry, scanning, and transmission electron microscopy. The number of lysosomes, more prominent in nonmature variants, was found to decrease.
