title: Creatine kinase isoenzyme BB in serum of healthy adults and children.
abstract: The activity of the creatine kinase isoenzyme BB was determined in the serum of 26 healthy adults and 31 children. The isoenzyme BB could be proved as a normal component in the human serum. In the adults examined, an activity of 0.56 +/- 0.16 I.U./l (x +/- S.D.) was determined. The activity of creatine kinase isoenzyme BB in the serum does not depend on sex but is subject, however, to a strong age dependence. Only at an age of more than 18 years, isoenzyme BB activities adjust to those of adults.
