Abstract
Summary
A comparative evaluation of in vitro hepatic, splenic, and pulmonary macro-phage phagocytosis has demonstrated that serum opsonin can significantly augment the phagocytic activity manifested by all 3 macro-phage populations. Furthermore, liver and spleen phagocytosis of a gelatinized “Re test lipid emulsion” is more markedly influenced by opsonization than is lung phagocytosis. Opsonin activity represents a major factor in regulating RE phagocytic function in view of its ability to markedly enhance hepatic, splenic and pulmonary phagocytosis.
