Abstract

Intestine inflammatory diseases (IIDs) are characterized by a chronic inflammatory processes mainly, Crohn Disease (CD) and Ulcerative Rectocolites (URC). Natural products suggest therapeutic alternatives such as methyl jasmonate (MeJA) as a probable alternative treatment, with proven anti-inflammatory, anti-proliferative and antioxidant activities. The compound is isolated from the essential oil of Jasminum grandiflorum. Potential tissue and neuro-inflammatory effect of MeJA at 300 mg/kg in adult rats with colitis was induced by trinitrobenzenosulfonic acid (TNBS). Rats were divided into four groups and euthanized after treatment. Samples of distal colon of 20 animals were employed to obtain transversal histological cuts. Morphometric analyses of intestine tunics were undertaken by samples of images by optic microscope; antineuroinflammatory profile of the enteric nervous system was also undertaken by microscopic evaluation of 30 ganglia in the myoenteric ganglia per animal in counting and characterization of inflammatory cells. Efficient simulation of IID by TNBS was reported by reduction of inflammatory cells in enteric ganglia, especially lymphocytes and monocytes; tissue regenerative effect in the submucus and muscular tunics.
