[Behavior of phenoloxidase-containing cells in experimental granuloma]

Using the histochemical method for phenoloxidase (PO) in albino rats, the development of carrageenan granuloma was investigated. It is shown that especially those cells containing the methanol resistent PO activity are the cells which were be found during the formation of the granuloma. These findings support our earlier suggestion that POC are involved in the defence reactions.
