The number and segmental distribution of cell bodies of sensory afferents and sympathetic efferent innervating to the knee joint of the rabbit and the Formosan rock-monkey were investigated using retrograde transport with horseradish peroxidase (HRP). After injecting HRP into the articular knee joint capsule of the rabbits, labeled neurons were found in the ipsilateral L4-S2 dorsal root ganglia (DRG). However, following injection of HRP into the articular cavity of the knee joint in the rabbit and the monkey, labeled neurons were found in both the ipsilateral DRG (L5-S2 and L4-S1 of the rabbit and monkey, respectively) and in the ipsilateral sympathetic ganglia (SG) (L4-S3 (rabbit) and L3-S1 (monkey)). The majority of labeled neurons within the DRG and the SG were composed of medium and large neurons in the monkey and the rabbit, respectively. The present findings suggest that the sensory projections from and sympathetic projection to the knee joint in rabbits and monkeys are similar, but that both projections of monkeys were "shifted" one segment cranially compared to the rabbit on both projections.
采用辣根过氧化物酶（HRP）逆行运输法，研究了支配家兔和台湾猕猴膝关节的感觉传入和交感传出神经元胞体的数量及节段分布。将HRP注入家兔膝关节囊后，在同侧L4 - S2背根神经节（DRG）中发现了标记神经元。然而，将HRP注入家兔和猕猴的膝关节腔后，在同侧DRG（家兔和猕猴分别为L5 - S2和L4 - S1）以及同侧交感神经节（SG）（家兔为L4 - S3，猕猴为L3 - S1）中均发现了标记神经元。DRG和SG内的大多数标记神经元在猕猴中由中大型神经元组成，在家兔中则分别由大型和中型神经元组成。目前的研究结果表明，家兔和猕猴膝关节的感觉投射和交感投射相似，但与家兔相比，猕猴的这两种投射在两个投射方向上均向头侧“偏移”了一个节段。
