Abstract: Objective:To observe the effects of hydrogen on osteogenic capacity of human periodontal ligament cells(hPDLCs)stim-ulated with P.g-LPS.Methods:hPDLCs were cultured and divided into 4 groups:control(C)group,osteogenic induction(OI) group,OI +1 00 ng/ml LPS(OILPS)group and OIPLS +3%H2 (H2 OIPLS)group,and treated respectively.Alizarin red staining (ARS)was carried out 3 weeks after treatment.ALP and OC mRNA expression of the cells was examined by RT-PCR after 7-d treat-ment.Results:LPS decreased A value of ARS(P <0.01 ),ALP mRNA expression(P <0.001 )and OC mRNA expression(P <0.001 )of the cells.H2 increased the A value(P <0.05),ALP mRNA expression(P <0.01 )and OC mRNA(P <0.01 )of the cells treated by LPS.Conclusion:High concentration of P.g-LPS can inhibit osteogenic capacity of hPDLCs,while hydrogen can impair the P.g-LPS induced suppression of hPDLC's osteogenesis.
