| Research Abstract |
After ethanol dosing to high acetaldehyde (ethanol metabolite) formation model (HAF) rats and aldehyde dehydrogenase 2 knockout (ALDH2-KO) mice, following results were obtained. 1. High acetaldehyde (AcH) levels were detected in the both HAF rats and ALDH2-KO mice, 2. the brain AcH levels were 1/5th-1/8th of the blood, 3. brain AcH levels of the HAF rats and ALDH2-KO mice pretreated with catalase inhibitors (sodium azide or 3-amini-1,2,4-triazole) were lower than those without pretreatment and 4. AcH reduced the mRNA expression of brain cholinergic markers in ALDH2-KO mice. These results suggested that AcH formation are performed in vivo brain through catalase activity and brain AcH has effects on brain cholinergic nerve neurons.
