Abstract: | Morphology and functional activity of peritoneal macrophages were studied at different intervals after the administration of blastolysin to Wistar rats. Alteration of the macrophage ultrastructure and their functional activity proving the stimulatory effect of the preparation on cells is shown. The signs of stimulation were revealed 30 minutes after the administration of the drug, reached a maximum on the 7th and 14th days and was manifested by structural changes of the cell surface, lysosomal apparatus, mitochondria and by activation of phagocytosis. |
