In vitro cytochemical and cytophysiological study of in vivo BCG-activated mouse peritoneal macrophages.

: The morphological, cytochemical (acid phosphatase activity) and cytophysiological (phagocytosis) features of mouse peritoneal macrophages activated in vivo by two bacterial agents. Corynebacterium parvum parvum and Polidin, were investigated in vitro. Both immunostimulants induced an increase in cytochemical and phagocytic activities of the activated peritoneal macrophages but in different degrees, the changes being more extensive in the case of Corynebacterium parvum-activated macrophages.
