[Modulation of granulocyte phagocytosis]

Non-specific complications are encountered relatively often in patients with below normal granulocytic phagocytosis rates. We tested vitamin C, transfer factor, gamma-globulin, BCG, PPD, UV irradiation of the subject's blood (UVB) and hyaluronidase with the aim of stimulating granulocytic phagocytosis with rice starch in autologous serum. In our experiments, only the addition of hyaluronidase caused any increase in phagocytotic activity. The in vitro experiments with hyaluronidase yielded promising results and will be followed up since they may be relevant to practical questions.
