北京鸭胃的传入神经元定位——HRP法研究

LOCALIZATION OF THE GASTRIC AFFERENT NEURONS OF THE BEIJING DUCK(Anas domestic L)——HRP METHOD

将HRP蒸馏水溶液注入北京鸭(Anas Dome8tic L)胃的肌层及浆膜下,逆行追踪了分布于北京鸭胃的传入神经元胞体的位置。结果表明:1.来自前胃的交感传入神经元胞体位于T_(1)~L_(1)各节中。集中存在于T_(1-6)各节,峰值在T_(3)脊神经节。2.来自前胃的迷走传入神经元胞体位于结状神经节和颈静脉神经节内。其中前胃腹侧肌注入HRP后,在颈静脉神经节出现标记细胞数最多。3.来自肌胃的交感传入神经元胞体出现在T_(1)~L_(1)。其前背薄肌区集中出现在T_(1-6),T_(3)最多;前腹厚肌、后腹薄肌和后背厚肌集中出现于T_(2-6),T_(4)内最多。4.来自肌胃的迷走传入神经元胞体主要存在于结状神经节。前背薄肌注射例,在颈静脉神经节内也出现标记细胞。

After the HRP solution was injected into gastric wall of the Beijing Duck,the afferent neurons of the stomach were retrogradely traced.The results arc as follows:1.The afferent sympathetic neurons from the proventriculus distribute in T_(1)-L_(1)spinal ganglia,concentrically in T_(1-6),the peak number is in T_(3).2.The afferent neurons of the vagus from the proventriculus arc present in the nodosal and jugular ganglia.After HRP was injected into the ventral muscle of the proventriculus,most of the labelled neurons were found in the jugular ganglia.3.From the gizzard,the afferent sympathetic neurons localize in T_(1)-L_(1)spinal ganglia.The muscle tenium craniodorsalis is concentrated in T_(1-6),the peak number in T_(3).The remained parts of the gizzard are concentrated in T_(2-6),the peak number in T_(4).4.The afferent neurons were retrogradely traced in the nodosal ganglia after HRP was injected into each part of the ventricul.But in the jugular ganglia labelled cells were found only in the region of the muscle tenuim craniodorsalis of the gizzard.
