Table 1.

IC₅₀ values of ARB on Vero cells as determined by the CPE method and MTT assay.

Drugs	TC₅₀ (μg/m)	HSV-2 (CPE assay)		HSV-2 (MTT assay)
Drugs	TC₅₀ (μg/m)	IC₅₀ (μg/mL)	SI^a	IC₅₀ (μg/mL)	SI^a
ARB	32.605 ± 0.02	5.045 ± 0.33	6.46	4.77 ± 0.29	6.82
ACV	195.64 ± 11.37	38.30 ± 6.67	5.11	33.135 ± 7.01	5.91

IC₅₀ (μg/mL) values and TC₅₀ (μg/mL) values were predicted according to the best fitting nonlinear regression formula calculated for each set of data.

“SI” is the abbreviation of “the selection index”. SI > 2 means low toxicity; 2 > SI > 1 means high toxic and low effect; SI ≤ 1 means no effect.
