title: Volatile anesthetic effects on inositol trisphosphate-gated intracellular calcium stores in GH3 cells.
abstract: The experimental results reviewed in this article indicate that clinically relevant concentrations of halothane (and isoflurane and octanol) cause calcium to leak from IP3-gated intracellular calcium stores, resulting in depletion of the stores. Depletion of intracellular Ca2+ stores should attenuate the actions of a variety of hormones and neurotransmitters that use the IP3 pathway to produce their effects, potentially contributing to many volatile anesthetic side effects including bronchodilatation, vasodilatation, and unresponsiveness to vasoconstrictive agents.
