Abstract

Malignant hyperthermia occurs in humans with several congenital myopathies, usually in response to general anesthesia. Commonly, individuals who develop this syndrome lack symptoms of muscle disease, and their muscle lacks specific pathological changes. A biochemical marker for this myopathy has not previously been available; we found activity of adenylate cyclase and content of cyclic AMP to be abnormally high in skeletal muscle. Secondary modification of protein phosphorylation could explain observed abnormalities of phosphorylase activation and sarcoplasmic reticulum function.

摘要

恶性高热发生于患有几种先天性肌病的人类,通常是对全身麻醉的反应。一般来说,出现这种综合征的个体没有肌肉疾病的症状,其肌肉也没有特定的病理变化。此前一直没有这种肌病的生化标志物;我们发现骨骼肌中腺苷酸环化酶的活性和环磷酸腺苷的含量异常高。蛋白质磷酸化的继发性修饰可以解释观察到的磷酸化酶激活和肌浆网功能异常。
