چکیده
Young albino rats (120-190 g) were divided in 4 groups (6 animals per group). One group was injected with clonidine hydrochloride (100 ",g/kg. ip); another group received equivalent volume of normal saline only. The third group also received clonidine but was given phenoxybenzamine hydrochloride (10 mg/kg. ip) 1 hr before clonidine Injection. The fourth group received phenoxybenzamine hydrochloride (10 mg/kg. ip) alone.

The Effect of Swimming Endurance Exercise on Cell Death and Nicotinic Acetylcholine Receptor Gene Expression in Brain of Rat: An Experimental Study of Alzheimer's Disease Model
Background and Objectives: Alzheimerchr('39')s disease (AD) is a neurodegenerative disease which is marked by impaired cholinergic function and decreased nicotinic acetylcholine receptor (nAChRs) density. nAChRs are important mediators of cholinergic signaling in modulation of learning and memory function. In Alzheimer hippocampus is particularly vulnerable to specific degenerative processes an...
متن کاملThe role of spinal muscarinic acetylcholine receptors in clonidine-induced anti-nociceptive effects in rats.
We have examined the effects of intrathecal (i.t.) injection of the muscarinic acetylcholine receptor antagonist atropine on the clonidine-induced nociceptive effect in formalin-induced nociception in rats. The injection of 5% formalin into the hind paw caused biphasic nociceptive responses, and i.t. injection of clonidine inhibited both phases of the nociceptive response in a dose-dependent ma...
متن کاملEffect of methyldopa on brain cholinergic neurons involved in cardiovascular regulation. A study in conscious spontaneously hypertensive rats.
Chemical stimulation of brain cholinergic neurons in many species can produce hypertension. Recent studies in this laboratory have demonstrated that clonidine inhibits this central cholinergic pressor response by inhibiting the biosynthesis of brain acetylcholine. This study was designed to determine whether methyldopa, like clonidine, could inhibit brain cholinergic neurons involved in cardiov...
متن کاملThe role of central α-adrenergic receptors on imipramine-induced antinociception as revealed by formalin test in rat
In this study, the effect of α-adrenoceptor agents on imipramine-induced antinociception was investigated using formalin test. Intraperitoneal (i.p.) administration of imipramine at different doses (10-80 mg/kg) induced antinociception in both phases of formalin test. In addition, intracerebroventricular (i.c.v.) injection of imipramine (1, 5, and 10 µg/rat) did not elicit any effect, although ...

Teucrium polium L. (Lamiaceae) is used in the traditional medicine of Iran for the treatment of disorders of the gastrointestinal tract. The essential oil from the aerial parts of T polium was assessed for antispasmodic activity and compared with the effect of atropine and dicyclomine. Acetylcholine and KC I were used for induction of contraction on rat isolated ileum. Teucrium polium essen...
