Hypoxia-dependent changes of enzyme activities in different fibre types of rat soleus and extensor digitorum longus muscles. A cytophotometrical study

摘要: Summary Using cytophotometry activity changes of succinate dehydrogenase, glycerol-3-phosphate dehydrogenase and myofibrillar adenosine triphosphatase were measured in 3 fibre types soleus extensor digitorum longus muscles under normal experimental conditions. Fibres typed by means cytophotometrical data into slow-oxidative, fast-oxidative glycolytic fast-glycolytic ones. After hypoxia 20 min duration a significant increase enzyme activities was observed especially slow-oxidative fibres both muscles, e.g. increased 21% these muscle 23–26% muscle. Moreover, an 10% 28% 10–12% ATPase all measured. Treatment with Ginkgo biloba extract for months before exposure to resulted decreased These results could be interpreted as protective effect extract.
