Serum concentration of protein, triglyceride, beta-lipoprotein and cholesterol in Papua New Guinean highlanders.
In studies on human adaptation to low protein intake, sera from 18 male highlanders of Kalugaluvi in Papua New Guinea, where the main protein supply is from vegetables, were analyzed for concentrations of serum protein, triglyceride, beta-lipoprotein and cholesterol, using sera from Japanese males as controls. The serum protein concentration of the Papua New Guinean highlanders was slightly higher, albumin (A) lower and globulin (G) higher, as compared with the Japanese controls. The ratio of (A) to (G) was 1.4 for Papua New Guinean highlanders and 1.9 for Japanese. The concentrations of IgG, IgM, IgA, haptoglobin, prealbumin, alpha 1-acid glycoprotein, ceruloplasmin and transferrin were also determined by immunological technique. In comparison with Japanese sera, the concentrations of IgG and IgM of the sera of highlanders were significantly higher and the haptoglobin concentration was slightly higher. The concentrations of alpha 1-acid glycoprotein, ceruloplasmin, transferrin and IgA were similar to those of Japanese sera. A significant difference was noticed between Papua New Guinean highlanders and Japanese in serum total cholesterol concentration.
