beta-endorphin-like immunoreactivity (beta-ELI) was measured in the cerebrospinal fluid (CSF) of 36 patients with acute head injury and 12 controls. The mean values of beta-ELI in CSF of controls and patients with moderate and severe acute head injury were 51.9 +/- 5.6 pg/ml, 110.5 pg/ml, and 173.8 +/- 20.1 pg/ml respectively, with significant difference between them (p less than 0.05). The results showed that beta-ELI increased in CSF of acute head injury patients.
