Photobiomodulation Exerts Anti-Inflammatory and Antioxidant Effects Reducing the Development of Tumors Elicited by 4-NQO in the Mice Tongue.

Objective: Evaluate the influence of photobiomodulation in a model of oral carcinogenesis induced by 4-nitroquinoline-n-oxide (4-NQO).

Subjective: Ninety-six Swiss mice received topical application of 1% 4-NQO on tongue dorsum, for 20 weeks. The tongue was subjected to photobiomodulation with red (71.

Polysaccharide-rich extract of Genipa americana leaves protects seizures and oxidative stress in the mice model of pentylenetetrazole-induced epilepsy.

Plant polysaccharides have biological activities in the brain and those obtained from Genipa americana leaves present antioxidant and anticonvulsant effects in the mice model of pentylenetetrazole (PTZ)-induced acute seizures. This study aimed to evaluate the polysaccharide-rich extract of Genipa americana leaves (PRE-Ga) in the models of acute seizures and chronic epilepsy (kindling) induced by PTZ. In the acute seizure model, male Swiss mice (25-35 g) received PRE-Ga (1 or 9 mg/kg; intraperitoneal- IP), alone or associated with diazepam (0.

Anti-inflammatory and healing effect of the polysaccharidic extract of Opuntia ficus-indica cladodes in cutaneous excisional wounds in rats.

This study aimed to investigate the anti-inflammatory and wound healing effects of the polysaccharide extract from Opuntia ficus-indica cladodes (TPL-Ofi) using a rat cutaneous wound model. After anaesthesia, four 7-mm-diameter dorsal wounds per animal (n = 6/group for each experimental day of evaluation) were created in female Wistar rats using a surgical punch. The animals were treated topically twice daily with TPL-Ofi (0.

Hydrogels dressings based on guar gum and chitosan: Inherent action against resistant bacteria and fast wound closure.

Hydrogels made with depolymerized guar gum, oxidized with theoretical oxidation degrees of 20, 35 and 50 %, were obtained via Schiff's base reaction with N-succinyl chitosan. The materials obtained were subjected to characterization by FT-IR, rheology, swelling, degradation, and morphology. Additionally, their gelation time categorized all three hydrogels as injectable.

Polysaccharide-rich extract of Genipa americana leaves exerts anti-inflammatory effects modulated by platelet mediators.

Ethnopharmacological Relevance: Genipa americana L. (Rubiaceae) leaves are traditionally used to treat fever, pharyngitis, healing, luxation and bruises.

Aim Of The Study: This study aimed to investigate the anti-inflammatory effect of the polysaccharide-rich extract of G.
