abstract：:Bladder smooth muscle contraction is mediated by both direct calcium entry through the cell membrane, and by calcium induced calcium release (CICR) from the sarcoplasmic reticulum (SR) storage sites. Ryanodine is a neutral plant alkaloid which binds to an ion channel located on the SR membrane. Its effects in cardiac ...
