[Studies of the changes in the content of total serum protein and protein fractions of white Wistar laboratory rats in the process of ontogeny].

The authors examined the changes in the content of the total protein and the protein fractions during the process of Ontogeny in the Blood Serum of 10 female and 10 male random bred rats of the Wistar strain. The examinations were carried out on the fifteenth, thirtieth, sixtieth day of age and when the rats were one year old. The authors found that the content of the total protein in the blood serum in both sexes was increased with advancement of age alpha2-, beta- and gamma-globulin fractions showed a tendency to an increase with advancement of age. The fraction albumin + alpha1 globulin was diminished quantitatively with advancement of age in both sexes.
