Two lysimeters with diameter and height of 0.70 and 2.40 m, respectively, were prepared. The lysimeters were operated with and without leachate recirculation. The leachate produced were quantified and characterised every day for the quantity, pH and ORP （oxidation reduction potential）. Meanwhile, the BOD and COD parameters were characterised every once week. Based on the data of experimental results that the lysimeter with a recirculation gave positive effects on the degradation of waste in landfills, that is the degradation process becomes faster. This is indicated by the quantity and quality of leachate generated. The lyisimeter conducted with recirculation of leachate shew the quantity of leachate generated larger than the lysimeter without recirculation. While the quality of the leachate includes pH, ORP, made it shown that the degradation process is faster. These results operations, especially for young waste. BOD and COD indicate that leachate recirculation on lysismeter suggest that leachate recirculation can be performed on landfills展开更多

Methods One hundred and fifty cases were randomized into 3 groups, 50 cases in each one. In the embedding catgut group, the embedding catgut therapy was applied to Sānyīnjiāo （三阴交 SP 6）, Cìliáo （次髎 BL 32） and Guānyuán （关元 CV 4）. In the acupuncture group, the conventional acupuncture therapy was applied to Guānyuán （关元 CV 4）, Sānyīnjiāo （三阴交 SP 6）, Dìjī （地机 SP 8） and Shíqīzhuī （十七椎 EX-B 8）. In the western medicine group, indometacin was prescribed for oral administration, 25 mg, three times a day and fenbid was supplemented for the aggravated pain, 300 mg, twice a day. One session of treatment was one month in each group and 3 sessions were required totally. Before and after treatment, the symptom scores of dysmenorrhea were observed. Results The symptom scores of dysmenorrhea were all reduced obviously in three groups after treatment （all P0.05）. The result in the embedding catgut group was much more apparent as compared with that in the western medicine group （P0.01） and the acupuncture group （P0.05） separately. Of 49 cases in the embedding catgut group, 32 cases （65.3%） were cured clinically, 10 cases （20.4%） effective remarkably, 6 cases （12.2%） effective and 1 case （2.0%） failed. The total effective rate was 98.0%. Conclusion The embedding catgut therapy achieves the significant efficacy for primary dysmenorrhea. This therapy is simple in practice and deserves to be promoted in clinic.展开更多
