ABSTRACT
Objective To explore the protective effect of Red Sage Root on bronchopulmonary dysplasis(BPD) induced by hyperoxia in newborn rats.Methods On the 2nd postnatal day,SD newborn rats were randomly assigned to 4 groupsair and NS group(group Ⅰ),air and Red Sage Root group(group Ⅱ),hyperoxia and NS group(group Ⅲ),hyperoxia and Red Sage Root group(group Ⅳ).The rats in group Ⅲ and group Ⅳ were exposed to hyperoxia(the level of oxygen was 900-960 mL/L).The rats in group Ⅱ and group Ⅳ were injected with Red Sage Root intraperitoneally(10 mg/kg)daily.On 14 days after birth,6 rats in each group were killed.Lung histologic changes,radical alveolar counts(RAC)were monitored.Thiobarbituric acid method,nitrite method,2-nitroben zoic acid method were used to determine the concentration of malony ldialdengde(MDA),superoxidedismutase(SOD),glutathione peroxidase(GSH-Px) were monitored.Results 1.Group Ⅲ and group Ⅳ showed the inhibition of lung development and the evident lung fibrosis.In contrast to group Ⅰ and group Ⅱ,RAC in group Ⅲ and group Ⅳ decreased dramatically(Pa
