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 groups:air 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
