从七十年代起,国外对骨骼肌的纤维型,特别是对比目鱼肌的纤维类型研究较多,常把比目鱼肌作为典型的“慢红肌”。而国内尚未见这方面的报道。本文的目的是通过对几种哺乳动物和人的比目鱼肌琥珀酸脱氢酶在细胞内定位及染色程度,确定比目鱼肌的纤维型,计算各型纤维横截面的直径,为揭示骨骼肌形态结构与功能的相互关系奠定基础。材料和方法用成年小鼠5只(雄3、雌2),雌性大鼠9只、豚鼠5只(雄2、鼠3)、兔10只(雄6、雌4)、狗5只(雄2、雌3)和2个成年男性的比目鱼肌进行研究。动物用4%戊巴比妥钠(40mg/kg)麻醉,以钝性解剖暴露比目鱼肌,从肌腹中点取小块肌
From the seventies onwards, foreign countries on skeletal muscle fiber type, especially for the soleus muscle fiber type more often, the soleus muscle as a typical “slow red muscle.” The domestic has not seen this report. The aim of this paper is to determine the fiber type of soleus by determining the intracellular localization and staining of soleus muscle succinate dehydrogenase in several mammalian and human species, and calculating the diameter of each fiber cross-section. To reveal the morphological structure of skeletal muscle And the function of the interrelationship laid the foundation. MATERIALS AND METHODS Five female mice (male 3, female 2), 9 female rats, 5 guinea pigs (male 2, mouse 3), 10 rabbits (male 6, female 4) and 5 dogs 2, female 3) and two adult male soleus muscles. The animals were anesthetized with 4% sodium pentobarbital (40 mg / kg), blunt dissected to expose the soleus muscle, and small pieces of muscle
