ABSTRACT
Purpose:To evaluate the efficacy of ondansetron plus dexamethasone compared with metoclopramide plus dexamethasone against emesis induced by cisplatin (DDP) containing chemotherapy.Methods:53 malignant tumor patients received DDP containing chemotherapy. DDP was 20 mg/m 2 ,qd,from the first day to the fifth day;ondansetron was 4 mg plus dexamethasone 5 mg,qd,from the first day to the fifth day; metoclopramide was 10 mg plus dexamethasone 5mg,qd,from the first day to the fifth day. Results:The anti emetic rate of ondansetron plus dexamethasone was 82.6%,which was higher than that of metoclopramide plus dexamthasone (44.5%, P
ABSTRACT
Object To isolate and identify the artemisinin like impurities present in the mother liquor of synthetic dihydro artemisinin methyl ether, for the development of new drugs Methods Artemisinin like compounds in the synthetic mother liquor were isolated by chromatography Results 5 compounds were isolated and identified They were ? dihydroartemisinin methyl ether (Ⅰ); ?, 12 deoxy artemisinin 12 ol (Ⅱ); artemisinin (Ⅲ); octahydro 8 methoxy 4, 7 dimethyl furo benzopyran 10 yl acetate (Ⅳ) and 12 deoxy 11 en artemisinin (Ⅴ) Conclusion Compound Ⅴ was new
