NAD+ level. a The NAD+ level was significantly increased in the 1, 10, and 100 μM 4HR groups at 24 h after administration compared to that of the untreated control (*p < 0.05). Additionally, it was significantly increased in the 10 μM 4HR groups at 8 h after administration compared to untreated control (*p < 0.05). b The NAD+/NADH ratio was significantly increased in the 1, 10, and 100 μM 4HR groups at 24 h after administration compared to that of the untreated control (*p < 0.05). Additionally, it was significantly increased in the 10 μM 4HR groups at 8 h after administration compared to untreated control (*p < 0.05)
