Abstract: Mouse peritoneal macrophages (MPM) when elicited by the antioxidant ascorbic acid have been found to be significantly stimulatory, exhibiting marked alteration at the cellular and enzyme levels. Alterations recorded were as follows – cellular  yield per mouse, their protein content, lysosomal acid hydrolase levels and capability to phagocyte, all were significantly enhanced. The new stimulant was observed to produce no synergistic action on MPM when thioglycollate, BCG or endotoxin along with the same stimulated the latter. Levels of antioxidants like ascorbic acid and glutathione were found to be enhanced in elicited macrophages whereas superoxide dismutase levels varied when the three above stimulators were administered. However, the ascorbic acid elicited cells showed an increase in glutathione levels and a decrease in SOD levels but no change in total intracellular ascorbic acid levels. Further, though ascorbic acid interaction enhanced the phagocytic capability of MPM as compared to resident cells, no significant boosting of phagocytic process could be observed when each of three stimulators coupled with ascorbic acid was used for macrophage elicitation.
