Abstract:
This study was aimed to investigate the anti-inflammatory, diuretic effect and acute toxicity of Herb of Lanceolate Sedge. The mice were randomly divided into 5 groups, which were the physiological saline group, aspirin group (0.05 g·kg-1), high dose (HD), middle dose (MD) and low dose (LD) of water extract of Herb of Lanceolate Sedge (10, 5, 2.5 g crude drug per kg) group. Intragastric administration of medication was given to mice once a day for 3 days. Auricular swelling induced by dimethyl benzene was used in the model establishment to calculate the swollen ear degree and the swollen inhibiting rate. And rats were randomly divided into 5 groups, which were the physiological saline group, aspirin group (0.05 g·kg-1), high dose (HD), middle dose (MD) and low dose (LD) of wa-ter extract of Herb of Lanceolate Sedge (10, 5, 2.5 g crude drug per kg) group. Intragastric administration of medi-cation was given to rats once a day for 5 days. Carrageenan induced paw edema was used in the model establishment to calculate the paw swollen rate. And rats were randomly divided into 5 groups, which were the physiological saline group, Furosemide tablets group (0.01 g·kg-1), high dose (HD), middle dose (MD) and low dose (LD) of water extract of Herb of Lanceolate Sedge (10, 5, 2.5 g crude drug per kg) group. Intragastric administration of medication was giv-en to rats once a day for 5 days. Water-loaded was used in the model establishment to calculate the 5-hour urine amount. The maximum tolerance dose (MTD) was used in the determination of the acute toxicity. The results showed that the three groups of HD, MD and LD of water extract of Herb of Lanceolate Sedge had obvious inhibiting effects on the swollen ear degree and the swollen inhibiting rate among mice, and the paw swollen rate of rats. It had signif-icant increasing effect on the 5-hour urine amount. The MTD of intragastric administration of water extract of Herb of Lanceolate Sedge was 640 g crude drug per kg for mice. It was concluded that Herb of Lanceolate Sedge dis-played obvious effects on anti-inflammatory and dieresis with low acute toxicity.
