Methods and Findings in Experimental and Clinical Pharmacology

The present study explores pharmacologically on the model spontaneously beating 3H-noradrenaline pretreated guinea-pig atrial preparation the mechanism(s) by which the representative central nervous system (CNS) stimulant drug 3-methyl-3-ethylglutarimide (bemegride, MEG) and its representative CNS depressant homologue 3-methyl-3-n-butylglutarimide (MBG) affect transmitter release and the force and rate of atrial contraction and contracture, as well as the relevance of these atrial mechanism(s) to those involved in the production of drug-evoked convulsions and hypnosis in the mammalian CNS.

BACKGROUND: Epidemiological evidence of co-use of alcohol and areca nuts suggests a potential central interaction between arecoline, a major alkaloid of areca and a muscarinic receptor agonist, and ethanol. Moreover, the central cholinergic system plays an important role in the depressant action of ethanol and barbiturates. The purpose of this study was to investigate the effects of arecoline on pentobarbital- and ethanol-induced hypnosis in mice.

Trasina is a herbal formulation of some Indian medicinal plants classified in Ayurveda, the classic Indian system of medicine, as Medhyarasayanas or drugs reputed to improve memory and intellect. Earlier experimental and clinical investigations have indicated that the formulation has a memory-facilitating action. In this investigation, the effect of Trasina, after subchronic administration for 21 days, was assessed on two rodent models simulating some biochemical features known to be associated with Alzheimer's disease (AD).

To induce arthritis, the adjuvant with heat-killed Mycobacterium tuberculosis was injected into the ankle joint in rats. Local redness, swelling, hotness, pain, and motor dysfunction of the inflamed joint (as well as mental dullness) were observed 48 h after inoculation. At this time, the maximal binding capacity (Bmax) of muscarinic receptors in limbic system was increased, while the dissociation constant (Kd) was unchanged.
