Figure 5: Prolongation of pentobarbital-induced sleeping time by cinnabar in offspring mice. Offspring mice were administered with distilled water or cinnabar (10 mg/kg/day, oral application by gavage) as described in Figure 1. Sleeping time was measured at the end of 49 days after weaning as described in Materials and Methods. Data are presented as mean S.E. ( 12–15/group). * as compared with F1-C-V group; # as compared with F1- or F2-Cin-V group; & as compared with F1-C-Cin group, respectively.
