Objective: To investigate the effect of Hydrogen-saline on Lung Injury and HO-1 Expression in The Lung Tissue of Acute Paraquat-intoxicated mice.

Methods: 108 male clean-grade mice were divided randomly into 3 groups: normal control group (n = 8), PQ group (n = 50) and PQ HN group (n = 50), PQ group were lavaged with 20% PQ (50 mg/kg). PQ+Hyclrogen saline group were intxaperitoneal injected with 5 ml/kg saturated hydragen saline after lavaged, 2 times/d. We observe its performance after the poisoning, The lung tissue were taken to HE stained, MDA and SOD activity of lung tissue homogenate were detected, HO-1 activity were observed by immunohistochemistry and western method at 6 h, 1 d, 3 d, 7 d and 14 d.

Results: mice came to shortness of breath, exhaustion and death after poisoned. PQ+hydrogen saline group was more alleviative than PQ group. The lung MDA of PQ group was markedly increased at 6 h and 24 h and SOD was decreased at 6 h, 24 h, 3 d, 7 d, 14 d than normal control group. In Comparison with PQ group, the lung MDA was decreased at 24 h and SOD was increased at 24 h and 3 d (P < 0.05). HO-1 expression trend and distribution in PQ+hydrogen saline group are similar with PQ group, but were significantly higher than that of PQ group and the control group each time point (P < 0.05).

Conclusion: Oxidative stress plays important roles in lung injury caused by paraquat. Hydrogen-saline may increase expression of HO-1 and alleviate oxidative stress damage in lung.
