title: Ouabain potentiation of Ca release from fragmented cardiac sarcoplasmic reticulum from isolated cat heart.
abstract: The present study was performed to determine the effect of ouabain on Ca release from fragmented sarcoplasmic reticulum (FSR) isolated from cat cardiac muscles. The results clearly demonstrate that ouabain potentiates the Ca release from FSR by changing the ionic environment.
