Protein deficiency leads to a decrease in serum complement levels, whereas vitamin A deficiency enhances complement levels. Additional experiments to determine the relative rates of synthesis and catabolism of complement components in protein and vitamin A deficiency are required if the overall function(s) of these nutrients in determining serum hemolytic activities are to be fully understood. © 1978, SAGE Publications.
