Abstract
To demonstrate noradrenaline-immunoreactive nerve fibres in liver tissues, we used an antibody to noradrenaline in the immunostaining of liver tissues from rats, guinea-pigs and humans. The tissue specimens were fixed by perfusion or immersion with cacodylate buffer containing sodium metabisulphate and glutaraldehyde, and cryostat sections were prepared. An indirect peroxidase-labelled antibody method was used for staining noradrenaline. Noradrenaline-immunoreactive nerve fibres were localized around blood vessels in the portal area and around the central vein. There were differences between the species in the intralobular distribution of noradrenaline-immunoreactive fibres. Normal guinea-pig and human liver showed intralobular noradrenaline-immunoreactive fibres while rat liver did not. Noradrenaline-immunoreactive fibres were absent from regenerating nodules in a human cirrhotic liver. This method of demonstrating noradrenaline directly using perfusion- or immersion-fixation is appropriate for studying innervation in normal and damaged livers of various species including humans.
