Phagocytic Activity as Affected by Protein-Intake in Heat and Cold

[摘要] Increasing emphasis is now being placed on the rôle of body proteins in resistance to infection and on the maintenance of acquired immunity. Cannon's excellent discussion of the subject[1][1] pictures the loss of protein-attached immune bodies as tissue reserves of protein are depleted from any cause (blood-loss, proteinstarvation, and the malnutrition accompanying vitamin-deficiency, debilitating disease or old age). No mention has been made, however, of the part reduced phagocytosis might play in such loss of resistance. Hence we decided to study this phase of the subject in conjunction with our work on vitamin-deficiency and differences in protein-requirement in heat and cold.Using the phagocytic technic and basal diets described in the preceding paper, we have adjusted the protein- and sugar-content of the basal diet to give 6, 12, 18, 24, and 36 percent protein and corresponding reductions in sugar. All vitamins were kept at optimal levels, with the needed increases in thiamin and choline in the hot room. [1]: #fn-1
