Abstract

The granular spheres are constituted of granules of 300-350 A and show a higher contrast than the nucleolar part where they are localised. The micronucleoli consist of fine fibrils. These two structures contain RNP. A relation between the granular spheres and the degeneration of the pyriform cells is suggested. The RNP of the micronucleoli, probably synthesized on perinucleolar DNA, migrate into cytoplasm.

摘要

颗粒球体由直径为300 - 350埃的颗粒构成，并且与其所在的核仁部分相比呈现出更高的对比度。微核仁由细纤维组成。这两种结构都含有核糖核蛋白（RNP）。有人提出颗粒球体与梨形细胞的退化之间存在关联。微核仁的核糖核蛋白可能在核仁周围的DNA上合成，然后迁移到细胞质中。
