[Increase in phagocytosis by nonspecific antigens]

By determination of Wright's opsonic index (modified method) in man after application of penicillin simultaneously with and without an "unspecific vaccine" (Omnadin) as an immunostimulant, it was shown that Omnadin stimulates the phagocytosis of peripheral leucocytes while penicillin inhibits phagocytosis (compared with untreated control persons).
