摘要

在神经节前副交感神经阻滞后,仅在舌下腺胆碱能神经支配的黏液细胞中可以确定三个组织学和组织化学阶段。第一阶段的特点是生产过剩和分泌过剩。这可能是由于乙酰胆碱分泌过多,由阻滞引起,称为“变性分泌”,但起源于神经节前。腺体实质的超敏性似乎也存在,它与儿茶酚胺和乙酰胆碱一起引起随后的“麻痹性分泌”。在第一阶段结束时,部分细胞(很少是整个细胞)以分泌大汗液和全息分泌的形式脱屑,形成统一的细胞群。当这个细胞群发育时,第二阶段开始。由于乙酰胆碱耗竭而缺乏刺激被认为是第二阶段的原因。在第三阶段,开始自我调节。在双神经支配的浆液性颌下腺中,鼓室索切片的影响较轻。

[The sublingual and submandibular glands after preganglionic parasympathetic blockade. A histological, electron optical, autoradiographic and scintigraphic study on the guinea pig].

After preganglionic parasympathetic block three histological and histochemical phases could be determined in the only cholinergically innervated mucous cells of the sublingual gland. The first phase is characterized by overproduction and oversecretion. Possibly this results from acetylcholine overproduction, caused by the block, termed as "degeneration secretion" however of preganglionic origin. Hypersensitivity of the gland parenchyma appears to be present also, which with catecholamins as well as acetylcholine cause the ensuing "paralytic secretion". At the end of the first phase the desquamation of parts of cells, and rarely entire cells, in form of apocrine and holocrine secretion occurs and a uniform cell population is developing. When this cell population develops the second phase starts. The lack of stimulation because of acetylcholine exhaustion is discussed as the cause of the second phase. In the third phase a self regulatory involution commences. In the double innervated serous submandibular gland the effect of chorda tympani section was less severe.
