OBJECTIVE To discuss the possible etiopathogenetic mechanism of inner ear damage induced by the ingestion of potassium hydroxide (KOH). CLINICAL PRESENTATION AND INTERVENTION We report the case of a 37-year-old patient with sudden bilateral sensorineural hearing loss after accidental ingestion of a KOH solution. The first ear, nose and throat examination disclosed only mild edema of the upper...

Glycogen synthase kinase-3 (GSK-3) facilitates interferon (IFN)-γ signaling. Because IFN-γ is involved in inflammatory skin diseases, such as psoriasis, the aim of this study was to investigate the pathogenic role of GSK-3 in 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced IFN-γ-mediated ear skin inflammation. TPA (3 μg per ear) induced acute skin inflammation in the ears of C57BL/6 mice, in...

Potentilla species have been used in traditional medicine in the treatment of different ailment, disease or malady. Potentilla reptans (P. reptans) has been scarcely studied. The aim of this study was to test antioxidant and anti-inflammatory activity of P. reptans aerial part and rhizome. DPPH assay was used to measure antioxidant activity of aqueous plant extracts. Anti-inflammatory effect wa...

INTRODUCTION Sulfur compounds isolated from garlic exert anti-inflammatory properties. We recently isolated thiacremonone, a novel sulfur compound from garlic. Here, we investigated the anti-inflammatory and arthritis properties of thiacremonone through inhibition of NF-kappaB since NF-kappaB is known to be a target molecule of sulfur compounds and an implicated transcription factor regulating ...

Novel formulations of the halogenated corticosteroid, triamcinolone-acetonide, based on ultradeformable mixed lipid vesicles, Transfersomes, are described. Their performance was tested in vivo using radioactive label measurements, to study the drug biodistribution, and murine ear edema, to determine the drug bioactivity. Sparse use of drug-loaded Transfersomes on the skin ensures an almost excl...

This study was designed to investigate the anti-inflammatory and anti-nociceptive activity of the methanol extract from the aerial part of Phlomis younghusbandii (MEAP) and to explore the possible related mechanisms. Anti-inflammatory effects of MEAP were evaluated by using the ear edema test induced by dimethylbenzene and vascular permeability test induced by acetic acid. Anti-nociceptive acti...

Euphorbia hirta and Lactuca virosa are medicinal plants that have been used in the cure treatment of various diseases for health care. This study aims at evaluating anti-inflammatory activities aqueous extracts plants. Albumin histamine induced inflammation mice xylene ear edema were in-vivo studies. Erythrocyte membrane stabilization inhibition protein denaturation assays in-vitro Combined dos...

Background: Bovine mastitis is one of the most relevant and problematic diseases to treat and control in practice. Puxing Yinyang San (PYS) is a compound of herbs to treat bovine mastitis in China. This study was performed to evaluate the analgesic and anti-inflammatory activities of PYS in mice and rats. Materials and Methods: The analgesic and anti-inflammatory activities of PYS were determin...

Propolis is produced by honeybees and has many biological properties, including immunomodulatory, antiinflammatory, anti-oxidant, anti-bacterial, anti-viral and anti-cancer actions. Five ethanol extracts of Brazilian propolis were tested for inhibition of 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced inflammation in mice. The ethanol extract of Brazilian propolis AF-08 markedly inhibited T...

Ipomoea imperati (Convolvulaceae) lives on the sandy shores of the Brazilian coast and in other areas of the world. The anti-inflammatory activity of a methanol-water extract of the leaves of I. imperati was investigated in experimental models of acute and subchronic inflammation. Topical application of the extract (10 mg/ear) inhibited mouse ear edema induced by croton oil (89.0 +/- 1.3% by th...
