Serum protein, serum cholesterol, and inorganic phosphorus measurements were determined for 160 adult males. Height, weight, and age data were also collected. The serum proteins were separated into six components in terms of their electrophoretic mobility: albumin, α1 globulin, α2 globulin, β1 globulin, β2 globulin, and γ globulin. Analysis of the results showed that serum globulin fractions and total serum globulin increase linearly with age (P <.01), and decrease as weight increases (P <.05). Total serum cholesterol, cholesterol ester, and free cholesterol were not related to serum globulin fractions. Inorganic phosphorus was negatively related to the globulin fractions (P <.05). Serum albumin did not change with age, weight, height, cholesterol, or inorganic phosphorus. Albumin and globulin fractions were significantly related to each other (P <.01).

The development of a quantitative immunological technique using polyvalent antiserum permits a more logical approach to the fractionation of complex protein mixtures. In this study whole serum was separated by conventional gel filtration and the fractions obtained were analysed. This demonstrates over 60 immunologically distinct serum proteins. Because the current terminology is inadequate to describe this number of proteins, a temporary numerical nomenclature has been used.

Total serum protein values, hemocyte numbers, and muscle weights were determined for 216 intermolt lobsters immediately after their capture, and for 230 others held captive under a variety of dietary and environmental conditions. Average muscle values ranged from approximately 13% to the more normal 20–25% of the live animals' weight, depending upon experimental conditions. The total serum protein up to a level of 55 mg/ml was shown to be a reliable indicator of muscle weights, although the relationship was not identical for all lobster groups. It appeared to be modified chiefly by the areas from which the different groups were taken. Diet was more important than the temperatures (5 to 14 C) in affecting changes in muscle and serum protein values. Starvation caused a greater reduction (50 to 70%) in the size of the hepatopancreas than in the muscle. Histological examination of the hepatopancreatic tissue showed that the lipid content was markedly reduced upon starvation and that a degeneration of this organ was apparent for lobsters fed a beef liver and herring diet. Measurement of serum proteins would appear to be a useful technique in experiments on lobster nutrition and have value, within specified limits, for assessing the physiological condition of wild lobsters.

Total protein, serum protein, and lipoprotein electrophoretic distribution and hematocrit values were determined in two groups of men during acclimatization to 6 weeks of cold and 11 days of heat respectively. After 3 weeks of cold exposure total serum protein and albumin content decreased, while the globulin fractions increased; thus, the calculated albumin/globulin ratio was significantly depressed. During the last 2 weeks, these parameters gradually returned to control values. Overall, the protein changes during heat acclimatization were minimal, although the globulins decreased slightly, yielding a small increase in the albumin/globulin ratio. The hematocrit levels were significantly lowered during both environmental exposures, whereas the lipoprotein distribution remained essentially unchanged.
