The demographic characteristics of control and alcoholic subjects are given in Table 1. We found no significant differences in age (t28 = 0.01, P = 0.99), PMI (t28 = 0.85, P = 0.40) and proportions of smokers and nonsmokers (Fisher test, P = 0.5) between controls and alcoholics. All subjects were Caucasian male. Brain pH was determined to assess the agonal state. The mean brain pH of controls and alcoholics were 6.46±0.29 and 6.47±0.27, respectively, which was not significantly different (t28 = 0.11, P = 0.91).
