Relationship between facial flushing and blood acetaldehyde levels after alcohol intake.


Normal subjects were divided into two groups, i.e., those showing, and those not showing, facial flushing after consuming a small amount of alcohol. In the flushing group, increases of pulse rate, facial skin temperature and carotid arterial pressure and blood flow rate, as well as changes of digital plethysmogram and electrocardiogram, were found together with a conspicuous rise in blood acetaldehyde levels after the drinking. However, significant changes of the signs as mentioned above and elevation of blood acetaldehyde did not occur in the non-flushing group. The maximum blood alcohol levels and the rate of alcohol elimination showed not difference between these two groups. Furthermore, urinary excretions of epinephrine and norepinephrine increased in the flushing cases after the drinking.
