The effects of satureja hortensis l. Extract on cisplatin-induced behavioral alterations in the tail suspension test

Abstract

In order to evaluate the effects of Satureja hortensis L. extract on cisplatin-induced behavioral alterations in the tail suspension test (TST), we included 35 male Wistar albino rats in this study, divided into 7 equal groups. Cisplatin was administered (single dose of 7.5 mg/kg, i.p., on the fifth day) alone, and in groups with orally administered (for 10 days) Satureja hortensis L. extract (50, 100, and 200 mg/kg), and silymarin (100 mg/kg) in individual groups. The behavioral testing was performed in TST, and the following parameters were obtained: the latency to the first immobility, the number of immobility episodes, and the total duration of immobility. Cisplatin application increased the latency to the first immobility, but decreased the number of immobility episodes and the total duration of immobility. Oral administration of Satureja hortensis L. extract in a dose of 100 mg/kg attenuated cisplatin-induced alterations, and those effects were similar to silymarin group. The extract in a dose of 200 mg/kg diminished cisplatin-induced effect only for the total duration of immobility, while in a dose of 50 mg/kg, the extract had no impact on cisplatin effects. Although common use of this methodology would lead to a conclusion that cisplatin produced antidepressant effect, comparison with certain literature data allows the conclusion that this action of cisplatin may be attributed to its anxiogenic action that was attenuated by antioxidant supplementation (Satureja hortensis L.) in an adequate dose (100 mg/kg).
