黄芪皂甙对培养乳鼠心肌细胞感染柯萨奇B_3病毒的保护作用

采用1000TCID_(50) COX B_3病毒感染96孔培养板培养的SD乳鼠心肌细胞,分别于感染后1,4,8和24h加黄芪皂甙或黄芪,发现细胞培养液中LDH释放量均显著低于对照组,而DNA合成速率显著高于对照组(P<0.05)。病毒感染后48h培养液病毒滴度(Lg 3.78 TCID_(50)和Lg 4.33 TCID_(50)明显低于对照组(Lg 5.78 TCID_(50))。表明黄芪皂甙和黄芪均有保护心肌细胞免受COX B_3病毒感染的作用。

The Protective Effect of Astragalus saponins on Coxsackie B, Virus Infected New Born Rat Myocardiac Cells in Culture

The protective effect of Astragalus saponins or Astragalus mongholicus bunge on the micro -model of cultured new born rat heart cells infected with Coxsackie B, virus was observed. After inoculation with 1000 TCID Coxsackie B, virus, the cardiac enzyme lactic acid dehydrogenase (LDH) was much lower in the Astragalus saponins or Astragalus mongholiais bunge treated groups than in those untreated groups, but the synthesis rate of DNA was higher. Virus titer in the supernatant of cultures was detected 48 h after virus challenge. The virus titer of the Astragalus saponins (Lg 3.78 TCID) or the Astragalus mongholiais bunge (Lg 4.33 TCID50) treated groups was lower than in those untreated groups (Lg 5.78 TCID50). These results show that the Astragalus saponins may be a useful drug in treatment of acute viral myocarditis.
