Objective:Thisexperimentwasperformedto investigatethecalcificationof thecryopreservedaorticand pulmonaryhomograftsquantitivelyafterimplantation.Methods:Inoperationtheheterotopicimplantationof homo-graftconduitsintotheabdominalaortawasadopted.Thecalcificationof thehomograftconduitswasdeterminedby SX microelectronicprobeanalysis8wk afterimplantation.Results:Beforeimplantationthecalciumcontentof aor-tichomografts[(0.24±0.05)μg/mg]was significantlyhigherthanthatof pulmonaryhomograft[(0.13±0.02)μg/mg,P<0.01].Afterimplantationthecalciumcontentof arotichomografts[(0.53±0.09)μg/mg]was significantlyhigher thanthatbeforeimplantation[(0.24±0.05)μg/mg], withan increaseby(123.4±53.0)%(P<0.01),andso was thatof pulmonaryhomograftsfrom [(0.13±0.02)to(0.21±0.30)μg/mg],withan increaseby(63.8±35.8)%(P<0.01).And thecalciumcontentof aortichomograft[(0.53±0.09)μg/mg]wasstillsignificantlyhigherthanthatof pulmonaryhomo-graft[(0.21±0.03)μg/mg,P<0.01].Conclusion:In homograftconduitimplantationtheaortichomograftsaremore easilycalcifiedthanpulmonaryhomografts.TheMicroelectronicprobetechniquehasa greatsignificanceinelement componentanalysisof biologicalpreparation. 展开更多
