title: In vitro inhibition of alveolar macrophage phagocytosis by ozone: absence of a role for serum or mode of ozone administration.
abstract: Cell culture conditions which protected rat lung fibroblasts from O3-induced injury were tested for their protection potential in retaining the phagocytic activity of O3-exposed rat alveolar macrophages. Conditions which protected fibroblasts from O3-related loss of 51Cr were ineffectual in preventing O3-related loss of macrophage phagocytic activity. It is suggested that the macrophage phagocytic function may be especially sensitive to H2O2 generated by the O3.
