Evaluation of the cytotoxicity and intestinal absorption of a self-emulsifying drug delivery system containing sodium taurocholate

Fig. 10. Cell viability-concentration profiles with the MTT test. Human umbilical vein endothelial cells (HUVECs) were exposed to B-SMEDDSNR, PF-SMEDDSNR, B-SMEDDSR, or PF-SMEDDSR prior to viability testing. Data are presented as mean ± S.D. (n = 5). *P < 0.05 shows significant differences of B-SMEDDSNR and PF-SMEDDSNRversus B-SMEDDSR and PF-SMEDDSR. #P < 0.05 shows a significant difference between untreated cells and those treated with 324 μg/ml surfactant.75
