Figure 2. The cell viability of rabbit corneal epithelial (SIRC) cells cotreated with LFE and 1 MOI of HSV-1. The Statens Seruminstitut rabbit corneal (SIRC) cells were uninfected (mock) or infected with herpes simplex virus type I (HSV-1; 1 MOI) for 24 h, and meanwhile, Lychee flower extract (LFE) was added (0, 0.05, 0.1, and 0.2 μg/ml) or not (mock). Cell viability was measured with the Cell Counting Kit-8. Data are demonstrated as mean ± standard deviation (SD; n=3). Bars are mean ± standard error of the mean (SEM; p<0.05).
