catha/dopamine

Cathinone, the active principle of khat (Catha edulis), stimulates, excites and produces euphoric feelings in khat users. Locomotor and rearing activities, either individual or in groups, of male Swiss albino mice were decreased significantly compared to the control. Motor coordination tests

Locomotor sensitisation and deficits in prepulse inhibition (PPI) induced by psychostimulants are two paradigms that have been widely studied as animal behavioural models of psychosis. Clozapine is one of the atypical antipsychotic agents which has been widely employed to reverse the aforementioned

This study investigated the antinociceptive mechanisms of khat extract (100, 200, and 400 mg/kg, i.p.) in four pain models: two thermic (hot plate, tail-flick) and two chemical (acetic acid, formalin) models. Male mice were pretreated intraperitoneally (i.p.) with the opioid receptor blocker

The effects of repeated oral administration of the psychostimulant plant, Catha edulis and its active principle, cathinone on rats were studied using isolation induced aggression paradigm. The behavioral responses were videotaped and scored later by offline data analyses. Rats were decapitated at

A prolonged use of psychostimulants has been suggested to induce long-lasting behavioural sensitisation which plays a role in the acquisition and maintenance of addictive behaviour. A study was conducted to evaluate the effect of repeated oral administration of Catha edulis in rats. Male

There is behavioral evidence for the interaction between crude khat extract and the endocannabinoid system, whereby the endocannabinoid system alters khat extract-mediated behavioral effects through modulation of the monoaminergic system. The objective of this study was to investigate the role of

Khat (Catha edulis) is a plant that is deeply rooted in the cultural life of East African and Southwestern Arabian populations. Prevalent traditional beliefs about khat are that the plant has an effect on appetite and body weight. This review assesses the accumulated evidences on the mutual

We investigated the cumulative effects of cathinone on behavioural alterations in single-caged vervet monkeys. Fourteen adult vervets were divided into tests (12 animals) and controls (2 animals), and exposed to escalating doses of cathinone at alternate days of each week for 4 months in presence

OBJECTIVE To review the current understanding of the mechanism of action of cathinone, the active ingredient of khat. METHODS Published experimental studies on the nature and action and effect of cathinone on the central nervous system both in animals and humans. METHODS Data was taken from work

BACKGROUND The current study's aim is to evaluate the possible interaction effects of khat chewing on treatment of paranoid schizophrenic patients. METHODS In the study group, 42 male subjects suffered from paranoid schizophrenia and were classified according to their khat chewing habits into two
