^bP<0.05 vs. high-dose GE group

^cP<0.01

^dP<0.05 vs. control. Values are expressed as the mean ± standard deviation for groups. GE, Herba Gelsemii elegantis dichloromethane extract. A quantification assay is represented as the surface density and number density of positively stained cells. Surface density = area of positively stained cells/total statistical area; number density = number of positively stained cells/total statistical area.
