PG - 123-32 AB - A mutant strain, Nagase analbuminemia rats (NAR), was established from Sprague-Dawley rats. Age-related changes in plasma proteins of NAR were investigated to obtain information of their abnormalities of protein metabolism. The total protein concentration in the serum of NAR of various ages was almost the same as that of normal rats of the same age. The albumin level of NAR was less than 0.05 mg/ml at all ages examined. The concentrations of serum alpha 1-antitrypsin, alpha-X protein, alpha 2-macroglobulin, transferrin, ceruloplasmin, IgG, IgA and IgM were higher in NAR than in normal rats except for the perinatal stage, but alpha 1-acid glycoprotein level in NAR was normal. The serum transferrin and ceruloplasmin levels were especially high in female adult NAR. The plasma fibrinogen concentration was also increased in NAR. These findings indicate that the normal total serum protein level of NAR was maintained by increase in the globulin concentration.
