The action of halothane on stimulus-secretion coupling in clonal (GH3) pituitary cells.


The effect of halothane on the physiological response to excitatory stimuli was assessed in clonal (GH3) pituitary cells. Halothane, at concentrations used to produce general anesthesia in animals (0.25-0.76 mM), inhibited thyrotropin-releasing hormone (TRH)-induced prolactin (PRL) secretion. The sustained (extracellular calcium-dependent) phase of PRL… (More)
