1·There was a mild breakdown of myelin and many free ribosomes.

线粒体膜尚基本完整，髓鞘轻度崩解，游离核蛋白体多。

2·The NLB of loose structure was frequently associated with free ribosomes and cisternae of the rough endoplasmic reticulum.

结构疏松，边界不清的NLB与粗面内质网和游离核蛋白体关系密切。

3·The cytoplasm contained relatively few organelles, but might with moderate amount of free ribosomes, mitochondria and vacuoles.

细胞质内细胞器稀少，但可有中等量的线粒体、核糖体和泡状结构。

4·The ribosomes, made up of RNA and protein, are found either lining the endoplasmic reticulum or free within the cell.

核糖体由蛋白质和RNA组成，有的排列在内质网上，有的则在细胞中呈游离状态。
