Methods: Rat MC were incubated with angiotensin ⅱ( Ang ⅱ), To observe the proliferation and intracellular free calcium concentration by the MTT method and flurescence measurement with Fura-2/ AM after given the extracts from ASA. 方法:将血管紧张素Ⅱ(AngⅡ)作用于肾小球系膜细胞,加入不同浓度的积雪草提取物,采用MTT法和Fura-2/AM荧光指示剂负载测定MC增殖和细胞内[Ca2+]I的变化。
Higher concentration of readily biodegradable organics in raw water would inhibit the removal of MC by BAC. Most part of MC was degraded by microorganism ( BAC can be regenerated at some degree), and another part of MC was adsorbed by activated carbon. 原水中较高浓度的易生物降解有机物会抑制BAC对MC的去除,大部分MC可通过微生物降解去除(同时使活性炭得到一定程度的再生),部分MC通过吸附作用被去除。
Results IL-1 β could induce the proliferation of MC when the concentration was 0.1-100ng/ml in 12h, 24h and 48h. When its concentration was 2ng/ ml, it had the strongest effect in 24h. 结果IL1β在12、24、48h,浓度为0.1~100ng/ml时均有促MC增殖的作用,其中以孵育24h、浓度为2ng/ml时作用最强。
The recoveries of MC-LR and MC-RR were 90.10% and 91.31%. The research was carried on the impact of MC produced by environmental factors ( including temperature, light, initial concentration of nitrogen and phosphorus). 其中MC-LR及MC-RR的加标回收率分别是90.10%和91.31%。研究围绕影响微囊藻毒素产生的环境因子(包括温度、光照、起始氮磷浓度)展开。
While, how high concentration P4 affect MC PGR in endometritis, and regulate MC release medium should be further researched. 而子宫内膜炎时,高浓度P4如何通过MCPGR,调控MC介质释放,还有待于深入研究。
The results illustrated every index tested prove that the inhibition of microcystin on plant growth is remarkable, when the medium contains microcystin ( especially on high concentration). 实验结果表明,当培养基中含有MC时(特别是高浓度MC),各个检测指标都显示出植物的生长受到了较为显著的抑制。
