Changes in the cystometric parameters. (A) Blood pressure in the Wistar-Kyoto (WKY) rats and in the spontaneous hypertensive rats (SHRs) (B) Representative cystometry curves (M represents the magnification of the cystometry curve). (C) Changes in the intercontraction interval. (D) Changes in the basal contraction pressure. (E) Changes in the basal contraction time. *P < 0.05 compared with the WKY group. #P < 0.05 compared with the SHR group.
