在临床上,测定胃肠运动性多在食道下端进行,但这一段平滑肌的特性不同于胃肠平滑肌。许多有关胃肠平滑肌的基本生理学知识来自对动物结肠带的研究,有些离体实验结果对人体结肠带也是有用的。结合结肠记录的临床意义不断增加这一事实,本文以人体结肠作为主要综述题材。一、离体研究在离体实验中,可以在严格控制的条件下,对独立的肌细胞群进行观察记录。最近,对人体乙状结肠纵行肌细胞(由外科手术时获得标本)进行了细胞内
Clinically, the determination of gastrointestinal motility and more in the lower esophagus, but the characteristics of this section of smooth muscle is different from the gastrointestinal smooth muscle. Many of the basic physiological understandings of gastrointestinal smooth muscle come from the study of the zona pellucida, and some of the in vitro results are also useful for the human colon. Combined with the fact that the clinical significance of colonography is constantly increasing, this article uses the human colon as the main review topic. First, the in vitro study In vitro experiments, under the strict control of the conditions, the independent muscle cell groups were observed and recorded. Recently, the human sigmoid colon longitudinal muscle cells (obtained by surgical specimens) intracellular
