Ultrastructural distribution of acid phosphatase and adenosine triphosphatase was studied in the receptor elements of HERBST and GRANDRY sensory corpuscles. Acid phosphatase activity was established in the elements of smooth and rough endoplasmic reticulum of perineural capsule cells, as well as in the secondary lysosomes of all cell types. Particular interest was paid on the activity of myelin-like dense bodies and some clear core vesicles belonging to the axoplasm of receptor nerve fibres. Adenosine triphosphatase activity was established on the membranes of receptor structures and pinocytotic vesicles. More deposits of electron dense material were localized on the axolemma of the non-myelinated portions of the receptor nerve fibres. The functional significance and importance of the both enzymes in the receptor structures was discussed.
研究了赫布斯特小体和格兰德里小体感觉小体受体元件中酸性磷酸酶和三磷酸腺苷酶的超微结构分布。在神经周膜细胞的光滑和粗糙内质网元件以及所有细胞类型的次级溶酶体中均发现了酸性磷酸酶活性。特别关注了受体神经纤维轴浆中髓磷脂样致密小体和一些清亮核心小泡的活性。在受体结构和胞饮小泡的膜上发现了三磷酸腺苷酶活性。更多电子致密物质沉积位于受体神经纤维无髓鞘部分的轴膜上。讨论了这两种酶在受体结构中的功能意义和重要性。
