ANTI-INFLAMMATORY AND ANTI-ULCEROGENIC ACTIVITIES OF CHANTALEELA RECIPE

Chantaleela recipe is indicated for relieving fever in Thai traditional folk medicine. In the present study, Chantaleela recipe was investigated for anti-inflammatory, analgesic, antipyretic and anti-ulcerogenic activities. In preliminary investigation Chantaleela recipe was found to exert an inhibitory activity on the acute phase of inflammation as seen in ethyl phenylpropiolate-induced ear edema as well as in carrageenan-induced hind paw edema in rats. The results suggest that the anti-inflammatory activity of Chantaleela recipe may be due to an inhibition via cyclooxygenase pathway. In the analgesic test, Chantaleela recipe showed a significant analgesic activity in both the early and late phases of formalin test, but exerted the most pronounced effect in the late phase. The analgesic activity of Chantaleela recipe may act via mechanism at peripheral and partly central nervous system. In antipyretic test, Chantaleela recipe significantly decreased rectal temperature of brewer’s yeast-induced hyperthermia rats, probably by inhibiting synthesis and/or release of prostaglandin E2 in the hypothalamus. Therefore, the key mechanism of anti-inflammatory, analgesic, and antipyretic activity of the Chantaleela recipe likely involves the inhibition of the synthesis and/or release of inflammatory or pain mediators, especially prostaglandins. The oral administration of the Chantaleela recipe reduced ulcer formation in acute gastric ulcer models (EtOH/HCl-, indomethacin-, and stress-induced gastric lesions). In contrast, this recipe did not reduce the secretory rate, total acidity, and increase pH in rat stomach. These results indicated that Chantaleela seem to possess anti-ulcerogenic effect. This activity may be due to the increase of gastric mucosal resistance or potentiation of defensive factors and/or the decrease of aggressive factors but did not associate the anti-secretory activity. Moreover, the high oral doses treated did not cause acute toxicity in rats and the long term oral administration did not produce gastric and ileum lesions.
