Inhalation of hydrogen gas reduces liver injury during major hepatotectomy in swine

Figure 3 Changes of hepatic malondialdehyde, hyaluronic acid, tumer necrosis factor-α and interleukin-6 levels in two groups. A bar graph shows the mean ± SD of hepatic malondialdehyde (MDA) (A), hyaluronic acid (HA) (B), tumer necrosis factor (TNF)-α (C) and interleukin (IL)-6 (D) level in two groups. Each group is represented by the mean of 7 swines. A, B: In hydrogen gas treated-group, the MDA (A) and HA (B) levels were significantly lower to Contrast-group; C, D: In hydrogen gas treated-group, the TNF-α (C) and IL-6 (D) levels were significantly lower to Contrast-group. Pre-op: Pre-operation. ^bP < 0.01 vs MDA level in Contrast-group; ^dP < 0.01 vs HA level in Contrast-group; ^eP < 0.01 vs TNF-α level in Contrast-group; ^fP < 0.01 vs IL-6 level in Contrast-group.
