Figure 4. Transient inhibitory effect of MTEP on isovolumetric rhythmic bladder contractions during AA distension.

A, recordings showing examples of complete inhibition of reflex bladder contractions during a short period after administration of MTEP (indicated by arrows).B, average duration of the complete inhibition increases with cumulative MTEP doses.n = 6 cats. Note: results inBexclude the data from tests where the MTEP-elicited transient inhibition was absent (i.e. duration = 0 min, see 3 mg kg⁻¹ dose inA). The number beside each data point indicates the number of animals that exhibited the transient inhibition.
