The relative density of adrenergic and non-adrenergic nerves in the hepatic portal vein of the rabbit has been determined ultrastructurally. Adrenergic nerves were visualised with the modified chromaffin procedure of Tranzer and Richards (1976). Nearly equal numbers of adrenergic and non-adrenergic nerve profiles were found, indicating a much greater density of innervation by non-adrenergic nerves than that described by Burnstock et al. (1979) using light microscopic histochemical methods. These results imply that part of the argument used by Burnstock et al. (1979) to support "purinergic" transmission in rabbit portal vein is probably invalid.
已通过超微结构测定了兔肝门静脉中肾上腺素能神经和非肾上腺素能神经的相对密度。采用Tranzer和Richards(1976年)改良的嗜铬细胞法使肾上腺素能神经可视化。发现肾上腺素能神经和非肾上腺素能神经纤维的数量几乎相等,这表明非肾上腺素能神经的神经支配密度比Burnstock等人(1979年)使用光学显微镜组织化学方法所描述的要高得多。这些结果表明,Burnstock等人(1979年)用于支持兔门静脉中“嘌呤能”传递的部分论据可能是无效的。
