abstract：:Age related change of the human minor pectoral muscles was biochemically demonstrated. Myosin-ATPase activity was significantly decreased with age, and was activated with Tris. The degree of the activation by Tris was observed to be lower in old aged patients than in the young. Furthermore, at low concentration of CaC...
