Effect of nutmeg on ethanol and d-amphetamine-produced alteration of locomotor activity in the mouse
Abstract:
A behavioral performance test was used to assess the effect of a mild nutmeg extract on spontaneous locomotor activity of the mouse. The nutmeg extract was administered intraperitoneally once daily for 17 consecutive days and only moderately reduced motor activity from corresponding control. A nutmeg dosage devoid of action on motility was chosen for short-term administration to mice. These nutmeg treated mice and the saline controls received either a single depressant dosage of ethanol or a stimulant dose of d-amphetamine. Nutmeg treated mice showed potentiation of ethanol-mediated depression on motility compared to controls. The d-amphetamine-produced stimulation of locomotor activity was decreased from controls by the nutmeg treatment. The results indicate that the nutmeg extract preparation used contained ingredients which synergistically interacted with alcohol as contrasted with their antagonism to d-amphetamine. The results suggest a CNS depressant action of nutmeg. Such CNS impairment by nutmeg may conceivably contribute to its toxic interaction with certain substances of abuse and may explain, in part, its addictive potential.
Insights
This study found that nutmeg extract potentiates alcohol
Area of Science:
- Neuroscience
- Pharmacology
- Behavioral Science
Background:
- Nutmeg is a common spice with a history of medicinal use.
- Interactions between nutmeg and other substances are not fully understood.
- Central nervous system (CNS) effects of nutmeg require further investigation.
Purpose of the Study:
- To investigate the effects of nutmeg extract on mouse locomotor activity.
- To determine how nutmeg interacts with ethanol and d-amphetamine.
- To explore the potential CNS depressant properties of nutmeg.
Main Methods:
- Mice received daily intraperitoneal injections of nutmeg extract for 17 days.
- Locomotor activity was assessed using a behavioral performance test.
- Mice were subsequently administered ethanol or d-amphetamine to evaluate drug interactions.
Main Results:
- Nutmeg extract moderately reduced spontaneous locomotor activity.
- Nutmeg treatment potentiated ethanol's depressant effects on motility.
- Nutmeg treatment attenuated d-amphetamine's stimulant effects on locomotor activity.
Conclusions:
- Nutmeg extract synergistically interacts with alcohol and antagonizes d-amphetamine.
- Results suggest a CNS depressant action of nutmeg.
- Nutmeg's CNS impairment may contribute to its toxic interactions and addictive potential.
