Non-specific cholinesterase (nCHE) activity was demonstrated histochemically on electron microscope level in 3 parts of Pacinian corpuscles from the cat mesenterium. The reaction product was abundant on the plasmic membrane of the inner core lamellae. Schwann cells of a myelinated portion of a sensory axon in Pacinian corpuscles were devoid of positive reaction to nCHE activity. These results are in agreement with those obtained in other sensory nerve endings. Therefore, the cells investing the terminal portion of an unmyelinated sensory axon are considered to be specialized Schwann cells. Furthermore, the amount of end product was lower on the specialized Schwann cells around ultraterminal than terminal portion of a sensory axon. A significantly higher nCHE activity confined to the inner core around the terminal portion of a sensory axon suggests the participation of this enzyme in the maintenance of ionic milieu in periaxonal microenvironment.
在电子显微镜水平上，通过组织化学方法在猫肠系膜的环层小体的三个部分显示了非特异性胆碱酯酶（nCHE）活性。反应产物在内核板层的质膜上丰富。环层小体中感觉轴突有髓部分的施万细胞对nCHE活性无阳性反应。这些结果与在其他感觉神经末梢中获得的结果一致。因此，包裹无髓感觉轴突终末部分的细胞被认为是特化的施万细胞。此外，超终末周围特化施万细胞上的终产物量比感觉轴突终末部分的要低。局限于感觉轴突终末部分周围内核的nCHE活性显著更高，这表明该酶参与维持轴突周围微环境中的离子环境。
