The apoptosis induced by extract of russula subnigricans hongo was investigated in little white rat liver and kidney cells by agarose gel electrophoresis . the result showed that agarose gel electrophoresis of dna extracted from poisoned little white rat liver and kidney cells revealed typical 180 ~ 200bp integer - fold " ladder " " bands . apoptosis induced by extract of russula subnigricans hongo was dose - and time - dependentthe result indicated that extract of russula subnigricans hongo could induce apoptosis in little white rat liver and kidney cells 4 .用电泳技术研究亚稀褶黑菇粗毒液诱导小白鼠肝肾细胞凋亡,小白鼠亚稀褶黑菇抽提液中毒后,肝肾细胞. dna经琼脂糖凝胶电泳出现180一200bp整数倍的ona梯形带, 19 . 09 / l一28 . 59 / l范围内,亚稀褶黑菇提取液诱导肝肾细胞凋亡表现出时间和剂量依赖性
In vitro injury models of brain slice ( ogd and nmda insult ) and primary neuronal cultures ( nmda insult ) oxygen / glucose deprivation ( ogd ) - induced injury of rat hippocampal slice in vitro the rat hippocampal slices prepared were allowed to recover in the normal artificial cerebrospinal fluid ( acsf ) bubbled with gas mixture of 95 % o2 + 5 % co2 for 1 h , then they were thansfered to glucose - free nacsf which was bubbled with gas mixture of 95 % n2 + 5 % co2 . after treatment with ogd , the slices were placed into 2 % ttc solution in dark and incubated at 37 * cfor 1h . the slices were weighted and a 50 : 50 mixture of ethanol / dimethyl sulfoxide was then added to extract the formazan in dark for 24 h 离体脑片损伤模型( ogd和nmda )及原代培养神经元nmda损伤大鼠离体海马脑片缺氧缺糖( ogd )损伤大鼠离体海马脑片制备后,在通氧混合气的正常脑脊液( nacsf )中恢复60min ,然后移入通氮混合气的无糖脑脊液(吵化sf )中缺氧缺糖,取出脑片与2 ttc避光37 ’ c温浴60dll ,染色后根据每克湿重加入20ml抽提液(乙醇:二甲亚矾一50 : 50 ) ,在密闭容器内避光置24h ,测量前摇匀后取200pi至96孔板,在490urn波长,酶标仪测定各孔od值。
It could cleave the 18 kd peptide of psii and produce smaller peptides [ 5 ] . in order to detect the proteases in the nacl extract of psii particles , the sds - gelatin - page was applied in our experience , to identify and characterize proteases in the 1 mol / l nacl extract of spinach psii particles 为了进一步研究光系统中的各种蛋白酶,我们采用分离胶中加入0二5明胶作为底物的sds page ,对光系统颗粒及其lmol几naci抽提液中存在的蛋白酶进行了:分离、活性检测和性质分析。
