Fig. 4From: Effectiveness of activated carbon masks in preventing anticancer drug inhalationAbsorptive ability of the mask immersed in the CPA solution (n = 4). Fig. 4 indicated the absorptive ability of the mask immersed in the CPA solution. The determination in each group was repeated five times. Each bar indicated as mean ± standard deviation with □;Control (no mask), ;PCM, ;PAM, ;SAM, respectively. *, **, and *** indicated significant differences by Tukey test with less than 5 %, 1 %, and 0.1 % of hazard ratio as compared with Control, respectively. †† and ††† indicated a significant difference by Tukey test with less than 0.1 % and 1 % of hazard ratio as compared with PCM. ‡‡‡ indicated a significant difference by Tukey test with less than 0.1 % of hazard ratio as compared with PAM. 50–1000 μg/mL in the SAM indicated below the limit of quantificationBack to article page
