The Effect of Carbon Monoxide Intoxication on The Metabolites of Monoamine Neurotransmitters in Human Cerbrospinal Fluid

ABSTRACT

This study was done in order to show the effects of carbon rnonoxide (CO) induced hypoxia on the steps of metabolism of rnonoamine neurotransmitters. There were 9 patients exposed to CO and 5 patients of control group. We evaluated their cerebrospinal fluid within 24 hours after CO exposure. And we measured the amounts of 5-hydroxy-indole acetic acid (5-HIAA) and homovanillic acid (HVA) with high performance liquid chromatography (HPLC). In the CO exposure group, the levels of 5-HIAA and HVA were reduced compared with the control group. It was thought that the changes in the levels of 5-HIAA and HVA were due to the transient decrease in monoamine oxidase activity in acute hypoxia.
