Abstract
Summary
1) Alterations in various fractions of serum proteins and hematocrits were studied in hibernating and non-hibernating hamsters. 2) During hibernation the hematocrit, serum albumin and beta-globulins increased to a significant degree. The increase in beta-globulins was too large to be accounted for on the basis of simple hemoconcentration. Since concentrations of neither alpha 1 nor alpha 2-globulin increased, the data were interpreted to mean that total circulating quantity of these globulins decreased. A marked decline in concentration of gamma-globulin occurred.
