The number of noradrenergic and adrenergic neurons in the brain stem does not change with age in male Sprague-Dawley rats

We examined whether or not the number of noradrenergic and adrenergic neurons changes with age, using peroxidase antiperoxidase (PAP) immunohistochemistry with specific antisera against tyrosine hydroxylase (TH) phenylethanolamine- N-methyltransferase (PNMT). TH- and PNMT-immunoreactive neurons were...

More Information
Summary:We examined whether or not the number of noradrenergic and adrenergic neurons changes with age, using peroxidase antiperoxidase (PAP) immunohistochemistry with specific antisera against tyrosine hydroxylase (TH) phenylethanolamine- N-methyltransferase (PNMT). TH- and PNMT-immunoreactive neurons were counted in every noradrenergic and adrenergic neuron group of young (3-month-old) and old (24-month-old) rats. The differences in the counted number of TH- and PNMT-immunoreactive neurons did not reach statistical significance between the young and old rats.
