Abstract

Sarcoidosis is suggested to be a granulomatous disease with high‐turnover characteristics. In this paper the turnover of the inflammatory cells (the epithelioid cells) in lymph node granulomas from sarcoidosis patients is described. Uniform slices of granulomatous lymph nodes were incubated with ^3^H‐thymidine; autoradiographically the DNA‐synthesizing cells, parameter for local proliferation, were detected and the L.I. (labelling index) was determined.

We observed mostly low‐turnover reactions, incidentally granulomas with high‐turnover characteristics are found within the same lymph node.

The uptake of ^3^H‐TdR demonstrates that these granulomas could be in different stages of activation.

Proliferating cell nuclear antigen (PCNA) in gastric cancer was evaluated in relation to lymph node metastasis. A total of 125 gastric cancer patients who underwent gastrectomy were studied immunohistochemically. The PCNA-positive rate of the primary lesion with lymph node metastasis (47.6%) was sig
