Hypothalamic alpha adrenergic receptors and the regulation of LHRH release
… release is primarily under the control of the $\alpha$ adrenergic system. The $\alpha$ adrenergic receptor subtype mediating LHRH release has not been established however. Also, most investigators have used changes in plasma luteinizing hormone to infer changes in hypothalamic LHRH release, …

The effects of prolonged mechanical ventilation on the alpha-adrenergic responses of costal diaphragm arterioles
… diaphragm arteriole contractile responses to alpha-adrenergic agonists with no change in sensitivity. Methods: Female Sprague Dawley rats (5-8 mo) were randomly divided into spontaneous breathing (SB, n = 9) and prolonged MV (6 h MV, n = 6) groups. Following SB and 6 h MV, diaphragm arterioles …

A Study of the Adrenergic Receptors in Mammalian Tracheal Smooth Muscle
Adrenergic receptors of mammalian tracheal smooth muscle have been characterized. After beta-adrenergic blockade with propranolol, the responses to epinephrine in both human and guinea-pig tracheal smooth muscle were contractile. These dose-dependent contractions were blocked with the …

Pharmakologisch unterstützte manuelle Spermagewinnung und computergestützte Spermienkopfmorphometrie beim Breitmaulnashorn (Ceratotherium simum)
… analysis was performed. A combination of the alpha-2-agonist Detomidine-Hydrochloride (Domosedan) and the partial opioid agonist Butorphanol (Butomidor) was administered intramuscular. In order to provide adequate safety margins for the operating persons, important requirements consist in a …

A study of the factors controlling embryo transport in the oviduct of the mouse.
… pharmacologically, and the presence of alpha-adrenergic receptors is suggested. The musculature is proposed as the most important factor in isthmic transport. Removal of ovaries and adrenal glands resulted in a retardation of tubal transport which can be reversed by progesterone …

Behavioural assays of the effects of antidepressant drug treatment on the functioning of catecholamine systems
… effects of antidepressant drugs on central beta-adrenergic and dopaminergic receptor function were investigated using the anorexic effects of low doses of amphetamine and apomorphine as assays of beta-adrenergic function and presynaptic dopamine function respectively. Anorexia was typically …

Role of conceptus-induced vasodilation in controlling utero-ovarian function of ewes, cows and sows
… in vitro compared with UA from LP gilts, (alpha)-adrenergic receptor levels were reduced (P < 0.05) only for UA from FP and not P gilts compared with LP gilts. Experiment II: As observed for UA in experiment I, vasoconstriction of the ovarian vascular bed was reduced (P < 0.01) for FP (Days …
