[Xanthine oxidase of the cerebrospinal fluid in patients with craniocerebral trauma].

The authors studied the activity of xanthine oxidase (XO) and xanthine dehydrogenase (XDG) in the cerebrospinal fluid (CSF) of patients with craniocerebral trauma (CCT). XO and XDG activity in CSF appeared in moderate and severe CCT. XO in CSF was predominantly of cerebral origin. The possible role of XO in activation of lipid peroxidation in CCT is discussed. It is suggested that determination of XO and XDG activity in CSF should be used for evaluating the severity of the trauma.
