Methods Twenty four female Zucker rats were divided into four groups: lean rats + vehicle, lean rats + clofibrate, obese rats + vehicle, obese rats + clofibrate. Daily intraperitoneal injection of clofibrate (300 mg/kg) or vehicle (olive oil, 1 mL/kg) was given to the rats for two weeks.

选择瘦型和肥胖型Zucker大鼠24只，分为：瘦大鼠＋赋形剂组，瘦大鼠＋氯苯丁酯组，肥胖大鼠＋赋形剂组和肥胖大鼠＋氯苯丁酯组，分别给予腹腔内注射抓苯丁酯(300mg/kg)或赋形剂（橄榄油，1mL/kg）2周。

Results Clofibrate normalized plasma free fatty acid and cholesterol and reduced plasma triglyceride and insulin in obese rats. However, clofibrate led to accumulation of heart TG and increased myocardial long-chain unsaturated and monounsaturated fatty acids in obese rats. Conclusion Clofibrate aggravates myocardial triglyceride accumulation in female obese Zucker rats.

结果 氯苯丁酯可使肥胖大鼠血浆游离脂肪酸和胆固醇浓度恢复正常并可降低血浆甘油三酯和胰岛素浓度，可增加肥胖大鼠心肌甘油三酯的积聚，且心肌长链不饱和脂肪酸和单不饱和脂肪酸含量也相应增加。

On the basis of summarizing separation method of acetic acid-water system, we studied the azeotropic distillation process of acetic acid-water system, selecting butyl acetate, isobutyl acetate and isopropyl acetate as entrainers. The influence of packing height, ratio of water to entrainer and acetic acid initial concentration to separation effect of azeotropic distillation was studied in detail. Simulation calculations of general distillation and azeotropic distillation were carried out. The influence of reflux ratio, theoretical plate, feed position, feed temperature and feed concentration to distillation process were discussed. Preferred process operation parameter, which had guiding meaning to practical production of distillation process were obtained. Basic data for the process amplifying design of azeotropic distillation tower were provided. Invest and operation energy consumption of two distillation methods were compared. The elementary technical design of azeotropic distillation tower was carried out on the basis of result of simulation calculation. The type of major auxiliary equipments and inner parts of packed tower were selected.The research results are as follows:(1) Butyl acetate, isobutyl acetate and isopropyl acetate could be selected as entrainer, and separation effect was near.
