Abstract:
Objective To study anti-inflammatory and analgesic effects of extract from the roots and leaves of Citrulluslanatus and assess their acute toxicity in animals.Methods The mouse model with ear edema induced by xyleneand the rat model with paw edema or granuloma by carrageenin or cotton pellet were used for anti-inflammatoryeffects of the extract.Effects of the extract on analgesia was tested respectively by measuring the latency of micelicking hind foot from hot plates and by counting the times of body twisting in response to acetic acid.The acutetoxicity of the extract was determined with the method of Bliss.Results The extract significantly inhibited the earedema,granuloma hyperplasia,and paw edema.It significantly lifted the pain threshold on mouse hot-plateresponses and reduced their writhing times.During the 7 d observation period in its acute toxicity assay,no apparenttoxic reaction was shown and all mice survived at a dose of 87 g extract per kg body weight.Conclusion Theextract could protecte mice/rates from inflammation and analgesia,and may be safe as an orally administered naturalproduct for humans.
