Abstract

Skeletal muscle of guinea pigs is composed of at least three types of fibers which are distinguishable by their kinetic and histochemical properties. Fast twitch muscles may be histochemically red or white; fragmented sarcoplasmic reticulum (FSR) prepared from both types of fast twitch muscles has identical calcium-accumulating capacity (maximal calcium uptake) and calcium-concentrating ability. FSR from slow twitch muscles accumulates less total calcium, but the calcium-concentrating ability is equal to that of fast twitch muscles. The slower rate of calcium accumulation by FSR of slow twitch muscles correlates with a prolonged relaxation time.

摘要

豚鼠的骨骼肌由至少三种类型的纤维组成,这些纤维可通过其动力学和组织化学特性加以区分。快肌在组织化学上可能呈红色或白色;从这两种类型的快肌制备的破碎肌质网(FSR)具有相同的钙积累能力(最大钙摄取量)和钙浓缩能力。慢肌的FSR积累的总钙较少,但其钙浓缩能力与快肌相当。慢肌的FSR钙积累速率较慢与舒张时间延长相关。
