Abstract:
Objective To investigate the effect of curcumin on the hyperoxia-induced acute lung injury in neonatal rat.Methods A model of hyperoxia acute lung injury in neonatal rat was established by exposure to 95％ O2 for 3 days.After the model was established,40 rats were randomly divided into the treated group ( n =20) and the control group ( n =20).The 20 injured rats which were treated by curcumin ( 100 mg/( kg· d)were treated group,and the other 20 injured rats were control group.The 20 normal rats were blank group ( n =20).Lung tissues were collected for doing pathological section and measuring the levels of tumor necrosis factor(TNF)-a,interleukin(IL)-1β and myeloperoxidase(MPO) after 4 d and 7 d.Results The gross and micrographic injury of lung was milder in treated group than that in control group.The levels of TNF-α,IL-1β and MPO in treated group were significantly lower than those in control group at 4 d and 7 d ( P ＜0.05 ).Compared with the blank group,the levels of TNF-α,IL-1β and MPO in control group increased significantly at 4 d and 7 d ( P ＜ 0.01 ).Conclusion Curcumin can offer effective protection against acute lung injury induced by hyperoxia in neonatal rat.
