Introduction. The trans-isomer of resveratrol is the active ingredient of
Poligonum cuspidatum, known for its medicinal properties and traditionally
used in the treatment of neuropsychiatric disorders. It is also found
abundantly in the skin of red grapes and red wine. Previous studies have
suggested that trans-resveratrol demonstrates a variety of pharmacological
activities including antioxidant, anti-inflammatory, as well as
neuroprotective properties and procognitive effects. Objective. The goal of
the present study was to examine the influence of trans-resveratrol on
behavior in rats and its antidepressant properties. Methods. Male Wistar rats
were treated intraperitoneally (i.p.) with the increasing doses of
trans-resveratrol (5, 10 and 20 mg/kg) or vehicle (dimethyl sulfoxide -
DMSO), 30 minutes before testing of the spontaneous locomotor activity or
forced swimming. For the experiments, the behavior of the animals was
recorded by a digital camera, and the data were analyzed by one-way ANOVA,
followed by Tukey post-hoc test. Results. Testing of spontaneous locomotor
activity, after the application of vehicle or increasing doses of
trans-resveratrol, showed no statistically significant difference between
groups (p>0.05). In the forced swim test, one-way ANOVA indicated
statistically significant effects of trans-resveratrol (p<0.001). Tukey
post-hoc test showed that resveratrol significantly decreased immobility time
at the doses of 10 mg/kg and 20 mg/kg, manifesting the acute
antidepressant-like effects. There were no statistically significant
differences between the resveratrol treatment of 5 mg/kg and vehicle
(p>0.05). Conclusion. The results from our study suggest that
trans-resveratrol produces significant effects in the central nervous system.
After single application, it has acute antidepressant effects, but without
influence on locomotor activity.
