Abstract:
Objective To investigate the effect of puerarin on preeclampsia-like rat placental tissue hypoxia inducible factor (hypoxia-inducible factor,HIF)-1αexpression and study the mechanism of protective effects in rats.Methods 60 SD rats were randomly divided into control group,drugs intervention groups(low-dose,middle-dose,high dose)and model group.The rats in drugs intervention groups and model group were adopted endotoxin for induction of preeclampsia model.On the basis of the model group,low,medium and high dose groups were given 20.0,40.0,60.0 mg/kg puerarin by intraperitoneal injection,respectively.The blood pressure of tail artery,urine protein concentration were observed at different points and the expression of HIF-1αwere detected by PT-RCT in each group.Results The systolic blood pressure ,urine protein and HIF-1αprotein in model group were higher than control group(P<0.05 );serum NO concentration was lower than control group (P<0.05 );after the puerarin intervention,systolic blood pressure and urine protein concentration in drugs intervention groups were lower than model group (P<0.05 ),plasma NO concentration was higher than model group (P<0.05 )and HIF-1αprotein was lower than model group (P<0.05 );the placenta weight,weight and body length of newborn rats in drug intervention group were higher than model group (P<0.05 ).Conclusion Puerarin can reduce systolic blood pressure and urine protein levels,promote the level of NO in plasma and reduce HIF-1αlevel in placenta of rats.Puerarin can offer protection to rats with preeclampsia by decreasing the expression of HIF-1αin placental.
