Fig. 9. — Lack of effect of polyethylene glycol-conjugated (PEG)-catalase on whole-cell currents and STOCs in SMCs from SEAs. A and B: mean whole-cell current densities ± SE (n = 6 cells from 3 animals for Young and Old) in the absence (Control) and presence of PEG-catalase (500 U/ml). Two-way ANOVA revealed significant effects of voltage on mean current densities (P < 0.05), but no significant effect of PEG-catalase (P > 0.05) in both Young and Old. C–F: mean amplitude (in pA/pF; C and D) or frequency (in Hz; E and F) ± SE (n = 8 cells from 3 mice for Young and 10 cells from 4 mice Old) in the absence (PSS) and presence of PEG-catalase (500 U/ml). Paired t-tests revealed no significant effect of PEG-catalase on amplitude (P > 0.05) or frequency (P > 0.05) of STOCs in Young (C and E) or Old (D and F).
