The effects of C-48/80, histamine, and Hrh1 and Trpv1 modulators in bladder strips. (A) Experimental timeline for evaluation of C-48/80 and histamine. (B) Representative traces showing the effects of C-48/80 in the bladder strips from the control (left) and VCR (right) groups. (C) Summary of the baseline change with C-48/80. (D) Representative traces showing the effects of histamine in the bladder strips from the control (left) and VCR (right) groups. Myogenic spontaneous activities before (yellow shade) and after the application of histamine (purple shade) for comparison (lower images). (E) Peak contractile force in response to histamine with or without fexofenadine. (F) Effects of histamine on the amplitude of spontaneous activity with or without fexofenadine. Fold difference to the amplitude before application of histamine. (G) Peak contractile force in response to capsaicin with histamine. (H) Experimental timeline for the experiment with capsazepine. (I) Peak contractile force in response to histamine with capsazepine or fexofenadine. (J) Peak contractile force in response to capsaicin with histamine in the presence of fexofenadine. Mean ± SEM, *p < 0.05, #p < 0.005 vs. the control group. His histamine, Cap capsaicin, Fex fexofenadine, Cpz capsazepine.
