摘要
本实验用2~10%HRP水溶液,注入成年家兔的盲肠浆膜下和足三里穴区,并解剖了足三里穴区,观察该区腓深神经的组成。HRP藉内脏与躯体传入神经的摄取和逆行传送,在脊神经节中显示了其传入神经起源的胞体及节段分布。观察到盲肠和足三里穴区在脊神经节中的重合区。结果表明。1.盲肠的传入神经的标记细胞位于脊神经节C_(8)~S_(3)内,且多集中于T_(11)~L_(2)。2.足三里穴区的传人神经的标记细胞位于脊神经节L_(1)~S_(3),内,多在L_(6)~S_(2),这与解剖腓深神经的组成一致。3.盲肠与足三里穴区的传入神经的标记细胞在脊神经节L_(1)~S_(3)内为重合区。4.标记细胞以中、小型为多数,腰骶段脊神经节中标记细胞集中。此外,对HRP的应用,传人神经的分布范围,盲肠、胃和膀胱传入神经的节段性以及盲肠和足三里穴区的重合区的意义进行了讨论。
Ten adult rabbits(7 and♀3;body weights 1.5~2 kg)were selected for thee present study.A solution of 2~10%HRP(RZ=2.9)was injected into the subserosa of the caecum in seven rabbits and a solution of 5~10%HRP into the deep peroneal nerve of Tsusanli(足三里)region in the other three.The uptake and retrograds transmission of HRP in the afferent fibres of both the somatic and visceral nerves were traced to the spinal ganglia.The range of segments where the neurons from which these two afferent fibres originate overlap each other.The results are a follows:1.Labelled sensory neurons from the region of the caecum where HRP was injected are observed in the spinal ganglia C_(8)~S_(3)with a higher concentration in T_(11)~L_(2).2.Labelled neurons from the region of Tsusanli are found in the spinal ganglia L_(1)~S_(3)with a higher concentration in L_(6)~S_(2).3.The ranges of distribution of labelled neurons from the two groups of afferent fibres overlap in the segments L_(1)~S_(3).4.Most of the labelled cells are small and medium in size and the Iabelled cells are found more concentrated in the lumbosacral segments.
