METHOD FOR DETERMINATION OF MAXIMAL RATE OF CONTRACTION AND RELAXATION OF SMOOTH MUSCLE OF HUMAN INTESTINE IN EXPERIMENT

摘要

A method for determination of maximal rate of contraction and relaxation of smooth muscle of human intestine in experiment through measurement of the angles of inclination of tangent lines to registered in experiment curve of isometric contraction. Tangents of the maximal angle of inclination of the tangent line to the curve of isometric contraction are determined in phase of increase of amplitude to isoline of muscle tone at contraction of smooth-muscle cells of muscle preparation and maximal angle of inclination of tangent line to the curve of isometric contraction in phase of decrease of amplitude to isoline of muscle tone at relaxation of smooth-muscle cells of muscle preparation, those are numerical coefficients of those characteristics of contraction.
