摘要：

In the sera of a strain of rats with analbuminemia, the albumin concentration is less than a thousandth of that in normal rats. However, the total amount of serum proteins in the analbuminemic rats is almost the same as that in normal rats and no spots of additional proteins were observed on two dimensional gel electrophoresis. The half life of serum proteins as a whole in analbuminemic rats injected with [3H]-leucine was 3.0 days, being similar to that of 2.9 days in normal rats. The serum of analbuminemic rats gave 3 distinct peaks of protein and radioactivity (P1 to P3), while those of normal rats gave an additional peak of albumin (P4) on polyacrylamide gel electrophoresis. The half lives of P1, P2 and P3 were 4.2, 2.4 and 2.1 days, respectively in analbuminemic rats and 2.5, 1.7 and 2.3 days, respectively in normal rats. The concentrations of P1, P2 and P3 were 23.1, 19.9 and 20.9 mg/ml, respectively in analbuminemic rats and 4.4, 10.7 and 11.0 mg/ml, respectively in normal rats. The half lives of [3H]-labeled rat albumin injected into the blood of analbuminemic and normal rats were 8.0 and 3.5 days, respectively. © 1979 Academic Press, Inc.
