Morphine and related analgesics depress the responses of the isolated guinea-pig ileum to nervous stimulation and to drugs which act by stimulating the nervous structures of the intestinal wall. The present experiments show that these analgesics also depress the responses to smooth muscle stimulants which act directly on the smooth muscle fibres.
吗啡及相关镇痛药可抑制豚鼠离体回肠对神经刺激以及对通过刺激肠壁神经结构起作用的药物的反应。目前的实验表明,这些镇痛药还可抑制对直接作用于平滑肌纤维的平滑肌兴奋剂的反应。
