The retrograde transport of horseradish peroxidase (HRP) was used to trace afferents from the femoral-saphenous vein to the dorsal root ganglia in the cat. Afferents arising along the entire length of the vein projected to very localized spinal levels; 63% of the labeled cells counted were located in the L6 dorsal root ganglion, 37% were located in the L5 ganglion and less than 1% were located at other levels. Most of the cell bodies labeled by the application of HRP to the femoral-saphenous vein were small in size (diameter less than 35 microns). However, some large cell bodies (diameter greater than 50 microns) were also noted. It was estimated that over two-thirds of the femoral-saphenous venous afferents were C fibers; at least 15% were estimated to be A fibers. The largest venous afferents were predicted to conduct action potentials at approximately 60 m/s.
利用辣根过氧化物酶（HRP）逆行运输法追踪猫股隐静脉至背根神经节的传入纤维。沿静脉全长发出的传入纤维投射至非常局限的脊髓节段；计数的标记细胞中63%位于L6背根神经节，37%位于L5神经节，不到1%位于其他节段。将HRP应用于股隐静脉标记的大多数细胞体体积较小（直径小于35微米）。然而，也观察到一些大的细胞体（直径大于50微米）。据估计，超过三分之二的股隐静脉传入纤维是C纤维；估计至少15%是A纤维。预计最大的静脉传入纤维以约60米/秒的速度传导动作电位。
