RXPERIMENTAL AND CLINICAL STUDY OF CREATINE KINASE BB ACTIVITY FOR TH E DIAGNOSIS ON BRAIN DAMAGE / 药物分析学报

ABSTRACT

Objective To study the differential diagnosis o n cerebral concussion and mild cerebral contusion value of the brain type creati n e kinase isoenzyme(CK-BB),and evaluate the seriousness of brain damage and prog nosis of the patients with acute head injury.Methods Chromatographic separating and fluorometric quant ifying technique was used to detect the CK-BB activity in the cerebrospinal flu id(CSF) of 117 patients with acute head injury and 12 patients with increased in tracranial pressure and 20 normal people.Results The CSF-CK-BB activity of the patients with acu te head injury was remarkably higher than that of the normal people and the CSF -CK-BB activity increased with the seriousness of brain damage.There was a clo se relationship between CSF-CK-BB activity and prognosis,and higher activity o f CSF-CK-BB indicated poor prognosis.Conclusion CSF-CK -BB activity could be used as a new index to diagnose brain damage and evaluate the seriousness of brain damage and prognosis.
