摘要
将CT—HRP注入胆囊壁游离面,取脊神经节、迷走神经结状节作TMB法反应。结果是(1)胸2—13和腰1节段的脊神经节内有大量的标记细胞,右侧者数量占优势,左右胸7—10节标记细胞数量为高峰节段。(2)仅在右颈5—7脊神经节中发现不同数量的标记细胞,出现率约占实验动物的1/3,切断右侧膈神经后在颈部脊髓神经节中不出现标记细胞。(3)双侧迷走神经结状节中均发现标记细胞,左右侧在数量上无明显差异。脊神经节或结状节的标记细胞均以中小型为主,也有少最大型细胞。
Segmental distribution of the afferent nerves of gallbladder was investigated by the CT-HRP technique in the dog.CT-HRP(20-40μl)was injected into the wall of the gallbladder of the dog.After a survival period of 5-7 days,the dog was transcardially perfused and fixed.The dorsal toot ganglia,the nodose ganglia were sectioned and processed with TMB techniqug(Mesulam).The gallbladder of the dog was innervated by the dosal root ganglia T2-L1,right C5-7 and bilateral nodcse ganglia.Right cervical labeling was transported through the right phrenic nerve and was seen only in about one third of the subjects.In the dorsal root ganglia T2-L1,there is a peak of the number of CT-HRP positive cells at T7-10,with right side predominant.The afferent fibers seemed to trawel mainly via the celiac plexus and the greater splanchnic nerve.
