摘要：

The action of tryptanthrin, a known natural alkaloid, a potent inhibitor of cyclooxygenase COX-2 and 5-lipoxygenase, was studied in a model of dextran sodium sulfate (DSS)-induced mouse colitis by magnetic resonance imaging (MRI). It was shown that the intra-ventricular treatment with tryptanthrin suspensions or emulsion at a dose of 25 mg/kg effectively diminishes lethality at experimental groups and normalizes morphometric parameters of intestine in the treated animals. MR imaging confirmed anti-inflammatory effect of this alkaloid and its capability to decrease the size of bowel walls in animals with colitis.
