[The clinical significance of S100β protein in cerebrospinal fluid and serum from the patients with cerebral hemorrhage].

Aim: To observe the change and the clinical significance of S100β protein level in cerebrospinal fluid and serum from the patients with cerebral hemorrhage (CH).

Methods: ELISA was used to detect the expression of S100β protein in CSF and serum from CH patients control with Inguinal Hernia or great saphenous varix patients. Meanwhile, rabbit CH model at 6 h, 12 h, 24 h, 48 h, 72 h and 96 h .
