Evidence for Conversion of Methanol to Formaldehyde in Nonhuman Primate Brain

Figure 1

Formaldehyde (FA) levels in CSF samples following an i.c.v. injection of methanol in rhesus monkeys. FA levels in the CSF were measured at different time points. “0 h” refers to the point prior to the methanol injection. There was no significant difference until 18th hour after the methanol injection, albeit an increasing trend began after the 3rd hour. Data points represent the average CSF formaldehyde levels of the monkeys at each time point. All values are represented as the mean ± SEM. ; ; .
