Antiviral spectrum of Fr.8.3. A Plaque reduction test of HSV-2, B plaque reduction test of RV, C viral titers of RV, D real-time fluorescence quantitative amplification reactions (Q-PCR) assessing the DNA level of HSV-2. The results presented were obtained from three independent experiments. Data represent the mean ± SD. Statistical differences were analyzed via Student’s t test, and a value of p ≤ 0.05 was considered significant (^*p ≤ 0.05, ^**p ≤ 0.01, ^***p ≤ 0.001)
