家兎並びに蛙Glycerol筋の諸性質の比較

The effect of KCl-concentration of ATP contraction was studied in order to compare the properties of two glycerinated muscle fibers from rabbit's psoas and frog's sartcrius. The results are as follows. 1) Both glycerinated muscles show same contraction degree, irrespective of load. 2) Transparency and elasticity of both glycerinated muscles, increase siinilarily in accordance with the augmentation of salt-concentration. 3) From the above results, it is confirmed that the glycerinated muscle fiber extracted from frog's sartorius can be considered as suitable and proper material for models of AM system in addition to rabbit's psoas muscle fibers
