Abstract

The effect of Dehydroleucodine (DhL) on gastric acid secretion in rats was investigated at a dose of 40 mg/kg, while its anti-inflammatory effect was investigated in two experimental models: arthritis induced by Freund's adjuvant carrageenan- and cotton pellet-induced granuloma. DhL did not inhibit gastric acid secretion, suggesting that its anti-ulcerogenic effect can be attributed to its action on the mucosa defense factors. On the other hand, DhL inhibited both chronic and acute adjuvant carrageenan-induced inflammation phases, being most effective in the chronic phase. In the granuloma test, DhL also inhibited inflammation. It is suggested that the anti-inflammatory activity of DhL may be attributed to interference with multiple targets on the level of transcription factors, such as NF-kappaB, and cytokines.
