Abstract

Popularly used in India and sub-Hymalaian region, Moringa oleifera (Moringaceae) is associated with healing properties demonstrated in its use as treatment of acute and chronic skin diseases. Our study aimed at investigating the effects of M. oleifera seed oil (MOSO) in animal models for inflammatory and hyperproliferative skin conditions. MOSO was analyzed using gas chromatography/mass spectrometry. The anti-inflammatory and anti-hyperproliferative effects of treatment with either MOSO or oleic acid (OA), its main constituent, was evaluated. Acute and chronic inflammation was induced by applying 12-O-Tetradecanoylphorbol-13-acetate (TPA) and acute inflammation with either Arachidonic Acid (AA) or Phenol onto the ear of Swiss mice. Systemic activity and the influence of glucocorticoid receptors (GC) was also evaluated. Topical application of MOSO and OA inhibited ear edema caused by TPA, and Phenol. Only MOSO inhibited ear edema induced by AA. Neutrophil migration was also inhibited by treatment with MOSO. Topical application of MOSO, but not OA, significantly reduced chronic skin inflammation and epidermal hypertrophy induced by multiple TPA applications. Pre-treatment with GC antagonist mifepristone reversed the anti-inflamma...Continue Reading

Cell Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.

Anti-inflammatory Treatments

A drug or substance that reduces inflammation (redness, swelling, and pain) in the body. Anti-inflammatory agents block certain substances in the body that cause inflammation and swelling. Discover the latest research on anti-inflammatory treatments here
