Comparison of BSS plus, S-MA2, and Krebs–Ringer solution
| Solution | Transepithelial potential difference (mV) | Tissue resistance (Ωcm2) | Permeability(×10−6 cm/s) |
| BSS plus | 140 (47) | 4.8 (1.2) | 1.05 (0.16) |
| S-MA2 | 114 (16) | 5.6 (0.2) | 1.79 (0.29) |
| Krebs–Ringer solution | 127 (25) | 4.5 (1.6) | 1.89 (0.69) |
Values are mean (SD) in seven experiments.
↵Permeability of isolated RPE–choroid to carboxyfluorescein.
↵Between group difference was significant at p<0.01 (unpairedt test with Bonferroni’s correction for multiple comparison).
↵Between group difference was significant at p<0.05 (unpairedt test with Aspin–Welch’s correction for unequal variance and Bonferroni’s correction for multiple comparison).
