Ação do gel de Elaeoluma nuda aplicado pela fonoforese em artrite induzida por adjuvante em ratos lewis

Abstract

Physiotherapy uses phonophoresis to treat many diseases that affect the body and aims to relieve pain symptoms and improve functional capacity. Many native species from the Amazon are studied for topical application to human health. Some species show antirheumatic, antibacterial and antifungal actions. Considering the biological potential of Elaeoluma nuda in in vitro studies, this study evaluated the effect of the gel prepared with the extract of Elaeoluma nuda by phonophoresis on Adjuvant-Induced Arthritis in Lewis rats. The animals used herein were divided into: Group I: negative control - no induction and no treatment (n = 6), group II: positive control - with induction and without treatment (n = 6). Group III: induction and exposed to the therapeutic ultrasound treatment with conductive gel (n = 6) Group IV: induction and exposed to treatment by phonophoresis and gel of Elaeoluma nuda (n = 6) Group V: induction and exposed to the treatment by phonophoresis gel of diclophenac (n = 6). The antiedematogenic and anti-inflammatory effect were analyzed by pletismometria and flow cytometry. The effect of the aqueous gel of Elaeoluma nuda by phonophoresis on arthritis of the hind paw of rats was equivalent to diclophenac gel phonophoresis dietilomônio compared to positive control (p = 0.002), with reduction of arthritis in 33%. The therapeutic ultrasound without phonophoresis showed no significant effect until the 21st day of the experiment with only 2% attenuation of the arthritis. There were significant decreased levels of TNF-α and IL1-β (p = 0.0398 and p = 0.0278, respectively) for the group treated by phonophoresis with gel of E. nuda. The profile of the signature of high cytokines producers treated by gel of E. nuda was similar to as the negative control group while the group treated with therapeutic ultrasound showed a similar profile to the positive control. The results demonstrate the anti-inflammatory effects of the gel of E. nuda by phonophoresis on arthritis adjuvant-induced.
