Concentration of Total Protein and Protein Fractions of Sera from Pregnant Rabbits

임신가토(姙娠家兎)의 혈청총단백량(血淸總蛋白量)과 단백분획상(蛋白分劃像)에 대(對)하여

The total serum protein, protein fractions by paper electrophoresis and A/G ratio in pregnant rabbits were observed. The results obtained in this work were sumrnerized as follows: 1. Total serum protein and the fraction of serum albumin revealed a decrease with the advancing of gestation, especially total serum protein was decreased significantly on 3 weeks of pregnancy. There was a tendency to return tward control level on one week after delivery. 2. The fraction of ${\alpha}_1$, and ${\alpha}_2$-globulin showed little changes during the period of gestation. 3. The fraction of ${\beta}$-globulin was increased more or less during the period of gestation, and on one week after delivery showed considerable increase but the increase was statistically insignificant. 4. The fraction of ${\gamma}$-globulin revealed a variable changes during pregnancy but there was no significant differences. 5. A/G ratio was significantly decreased at 3 weeks of pregnancy and the ratio was near control level on one week after delivery.
