Fig. 6. Effects of quercetin glycosides on quercetin-induced IACh enhancement. IACh in oocytes expressing α7 nAChRs was elicited at a holding potential of ?80 mV for 30 s in the presence of 200 μM ACh. 100 μM quercetin (Que) alone or with 100 μM quercetin glycoside (Rham1, Rutin, Rham2) were applied for 30 s before ACh addition. Summary histograms are from three different frogs (n=7?12/group). Each point represents the mean ± S.E.M (*p<0.05, **p<0.005 compared to quercetin).
