The production of epithelial-derived IgG (expressed in µg/mL) by the vaginal epithelial cell line, VK2/E6E7 cells. The IgG levels were measured after 12 h of infection and the subsequent 24 h of co-incubation with the Baofukang suppository. V represents the vaginal epithelial cells cultivated alone; V+B represents the vaginal epithelial cells co-incubated with 20 µg/mL of teh Baofukang suppository for 24 h; V+C represents the vaginal epithelial cells infected with C. albicans for 12 h; V+C+B represents the vaginal epithelial cells infected with C. albicans for 12 h, then treated with 20 µg/mL of the Baofukang suppository for another 24 h. ***Significant difference compared to the V group (P < 0.0001), ^##significant difference compared to the V+C group (P = 0.025). Each sample was repeated three times. The error bars indicate the standard deviation
