Protective Effects of Hydrogen-Rich Saline on Rats with Smoke Inhalation Injury

Figure 1

Hydrogen treatment upregulated the activities of lung antioxidant enzymes and reduced the levels of lung oxidative product and inflammatory cytokine in rats induced by inhalation injury. (a) Lung SOD activity. (b) Lung MDA level. (c) Serum TNF-α level. 30 min after injury, normal saline and hydrogen-rich saline were injected intraperitoneally (5 mL/kg) in I+NS group and I+HS group, respectively. The serum and tissue were harvested for measuring these indicators at 24 h after inhalation injury or sham injury. The values are expressed as mean ± SD ( per group). versus S group; versus I+NS group.
