It wus established thut in the process of heating blood serum and plasma of healthy persons the bulk of serum albumin undergoes dcnalurution in the narrow temperature range Δθd/℃=4.0 with transition temperature, θd, about 60.5 ℃, with a weak diffusion transition at θd about 79.5℃ and Δθd/℃=12.0. The melting heat lor one gramme of blood serum was 5.2 cal. It was also i-stablisiu'tl that fibrinogcii in the composition of plasma of healthy persons denatured in two .swines with transition temperatures at 53.0 ℃ and 83.0 ℃. Tests distinguishing cancer from the nonn with the help of the thermal parameters of albumin and other dominant proteins in the composition ol blood plasma and scrum were devised.
