In vitro electrophysiologic effects of morphine in rabbit ventricular myocytes.

abstract：BACKGROUND:Mutations in the ryanodine type 1 receptor (RyR1) are causative for malignant hyperthermia. Studies in human B lymphocytes have shown that measurement of RyR1-mediated intracellular Ca(2+) (Ca(2+)(i)) release can differentiate between normal and malignant hyperthermia-susceptible individuals. The authors hav...
