Abstract
Normal gastrocnemius muscle of Wistar rats at various ages to 2 1/2 years was studied. No light microscopic or qualitative electron microscopic changes were seen. However, stereologic determinations revealed significant reductions in volume and surface densities of sarcoplasmic reticulum, t-tubular system, and glycogen content. These alterations were considered to be the morphologic expression of the very early age-related changes in gastrocnemius muscle.
摘要
研究了不同年龄直至2.5岁的Wistar大鼠的正常腓肠肌。未观察到光镜或定性电镜下的变化。然而，体视学测定显示肌浆网、横管系统和糖原含量的体积和表面密度显著降低。这些改变被认为是腓肠肌极早期与年龄相关变化的形态学表现。
