Abstract

Serum protein analysis by the method of paper electrophoresis were made for the purpose of comparison of their changes by age between breast milk-fed infants and cow's milk-fed infants of Korea. 79 cases of healthy breast milk-fed infants and 48 cases of cow's milk-fed infants ranging in age from birth to 14 months, were included in this study. The results obtained were as follows: 1.Total serum protein The values are increased gradually by age of months iii both group Of breast milk-fed And cow*s milk-fed infants, and slightly higher in later group after 5 months of Iife(Table 1, Fig. 1). 2.Albumia The concentrations are relatively constant through the age in both group, but slightly higher value noted in the breast milk-fed group(Table I, Fig. 1 & 2). 3.Total globulin They are increased gradually along with the age in both group and more pronounced in cow's milk-fed group(Table I. Fig. 1 & 2). 4.Globulins—Electrophoretic patterns i.Alphai lglobulin: constant through the age in both group, and no differences between both group CTablefl, Fig. 3). ii. AIpha2 2globulin: only slightly elevated, gradually by age, and little differances between both groupCTable D , Fig. 3). iii. Beta-globulin: no significant variations between groups and also by age(Table n, Fig. 4). tv. Gamma-globulin: these fractions decreased gradually during first 4 months and begin thereafter to increase with steep acclivity in both group, and conspicuously higher in cow's milk-fed group than breast milk-fed groupfTable D, Fig. 4).
