Abstract :
Acetylcholine (ACh) concentrations were determined serially in cerebrospinal fluid (CSF) obtained from 23 patients with aneurysmal subarachnoid hemorrhage (SAH) by high-performance liquid chromatography (HPLC) with electrochemical detection (ED). The values of CSF ACh were significantly low in the initial stage of SAH, and increased subsequently but they did not return to control values within 3 weeks. In addition, serial measurements of CSF butyrylcholinesterase (BChE) activity in 12 SAH patients showed that the activity was elevated significantly in the initial stage of SAH and returned to control levels within a week. This discrepancy in the recovery period between the ACh levels and the BChE activity in CSF indicated that significantly lower CSF ACh levels after SAH could not be attributed to plasma BChE contamination of CSF These results suggested central cholinergic dysfunction after SAH especially in the initial stage |
