Effects of histamine on alpha adrenergic receptor expression on the lymphocytes of normal and asthmatic subjects.
Low levels of [3H]-dihydroergocryptine (DHE) (alpha adrenergic receptor) binding to peripheral blood mononuclear leukocytes from asthmatic subjects were significantly increased following incubation with histamine. In contrast, [3H]-DHE binding was undetectable both before and after histamine incubation using cells from nonasthmatic subjects. The change in binding showed a biphasic dose dependence on histamine and was not associated with changes in DHA (beta-2 receptor) or yohimbine (alpha-2 receptor) binding. The induction of alpha adrenergic receptors by the ubiquitous inflammatory mediator histamine may help explain the alpha adrenergic hyperresponsiveness seen in asthmatic patients.

The treatment of asthmatic patients using an alpha-adrenergic receptor blocking agent, co-dergocrine mesylate ('Hydergine').
A study was carried out in 40 patients with bronchial asthma to assess the therapeutic effect of co-dergocrine ('Hydergine'), an alpha-adrenergic receptor blocking agent, when added to their standard treatment with a beta-adrenergic receptor stimulant and aminophylline. Co-dergocrine administration (3 to 6 mg per day) brought about marked improvement in 25% and an improvement in 55% of the patients. The results suggest that co-dergocrine could be a useful drug when combined with other bronchodilators in the treatment of bronchial asthma.
