Abstract
Mitochondria became larger and some numerous in the internal red fibers of M. quadriceps femoris and neck muscle in cold-acclimated rats than in warm-acclimated ones, while they became less in number in spite of remarkable increase of size in the external white fibers of the former muscle. Mitochondrial cristae and sarcoplasmic reticuli developed better in the muscles of cold-acclimated rats.
摘要
与暖适应大鼠相比，冷适应大鼠股四头肌和颈部肌肉的内部红色纤维中的线粒体变得更大且数量增多，而在前者肌肉的外部白色纤维中，尽管线粒体大小显著增加，但其数量却减少了。冷适应大鼠肌肉中的线粒体嵴和肌浆网发育得更好。
