The optical registration system for isometric contraction of smooth muscle

Abstract

The optical system registration of smooth muscle contraction in isometric mode was developed. Testing of system on smooth muscle strips of rat stomach and caecum was performed. It was tested the possibility of recording optical system spontaneous activity of smooth muscle. The resulting muscle contractions parameters correspond to the literature. Thus designed optical-mechanical method for detecting force and speed can be used for recording isometric contractions of smooth muscles of the stomach and caecum of rats and, therefore, to study the effect of different effectors their mechanokinetic.
