To compare the difference of drain and intake water then converse with biomass in sweetfish and walking catfish's grow-up pond. The ammonia-N, nitrate-N, nitrite-N and phosphate were 383.7, 208.99, 21.62 and 119.03 mg/kg in sweetfish's pond, respectively.

水中营养盐部分香鱼与胡鲇池换算流水量与生物量后，香鱼每增长1 kg，它所产生之氨氮、硝酸氮、亚硝酸氮及正磷酸酸盐的量分别为383.7、208.99、21.62和119.03 mg；胡鲇每增长1 kg则分别为68.76、5.72、2.44及13.80 mg。

MethodsThe OA rabbit model was established by immobilized in full extension for up to six weeks. Eighteen rabbits were randomly divided into the DEA group, the acupotomy group (treated with acupotomy and manipulation) and the control group (treated with manipulation alone). The treatment was applied once every three days for 1 month as a course. NO in articular synovia was measured by nitrate reduction method, and the apoptosis rate of chondrocyte was determined by flow cytometry.
