title: The effects of chlorbutol on skeletal muscle sarcoplasmic reticulum function in porcine malignant hyperpyrexia.
abstract: 1. Chlorbutol, a muscle relaxant, inhibits the in vitro muscle hypercontractility which is characteristic of the anaesthetic complication, malignant hyperpyrexia (MH). 2. Studies on isolated sarcoplasmic reticulum vesicles have shown that this effect of chlorbutol in MH is not due to a modification of Ca2+-transport mechanisms.
