title: [Study on the inhibitory effect of Reduqing Oral Liquid on respiratory syncytial virus in vitro].
abstract: OBJECTIVE
  To explore the antiviral effect of Reduqing Oral Liquid on respiratory syncytial virus (RSV).
  
  
  METHODS
  The anti-RSV effect of Reduqing Oral Liquid in Hep-2 cell culture was investigated by the cytopathic effect (CPE) inhibition assay and MTT assay, with ribavirin as the positive control drug.
  
  
  RESULTS
  Reduqing Oral Liquid was effectively antiviral agent for RSV in a concentration-dependent manner in vitro. The median toxic concentration (TC50) was 9182.4 mg/L, the median effective concentration (EC50) was 559.8 mg/L and the treatment index (TI) was 16.4.
  
  
  CONCLUSIONS
  Reduqing Oral Liquid has obvious inhibitory effect on RSV in vitro.
