Serial enzymatic determinations by electrophoresis were confined in serum of CK-BB(creatine kinase brain fraction), which were performed on 150 patients with acute head injury. The purpose of this study was to re-evaluate the usefulness of this serum enzyme value as a prognostic correlates. The results obtained are as follows : 1) 125 cases(83.3%) among 150 cases with head injury were revealed as CK-BB positive finding, whereas 25 cases (16.7%) with negative results have generally good outcome. 2) 3 cases (11.5%) of false positive finding were shown among 26 control group with back pain. 3) The maximum value of CK-BB(CK-BBmax) was een within 1st day(38.4%), and 3rd days (80.8%) following injury. 4) The appearance of mean CK-BBmax had two varieties of peak incidence on 1st-and 4th day following injury. 5) The Glasgow Coma Scale(GCS) Score on admission had close relationship to the value of inital CK-BB(CK-BBin) and CK-BBmax, respectively (P<0.001). 6) The ratio of mean value between CK-BBin and CK-BBmax had statistical significance in cases of skull fracture and contusional and/or intracerebral hemorrhage, respecitively (P<0.05, P<0.001). 7) The significant correlation of mean CK-BBin> or =1 IU.L) to outcome (P<0.003) was shown, whereas mean CK-BBmax> or =1 IU/L) to outcome did not (P=0.126). 8) The Glasgow Outcoem Scale (GOS) was strongly correlated to mean GCS Score (P<0.000) and mean CK-BBin (P<0.000), but not to mean CK-BBmzs (P<0.139). 9) The correlationship between mean value of CK-BBin and CK-BBmax was statistically significant only in good recovery and moderate disability group, respectively (P<0.000 & P<0.003).
