Memory acquistion deficit pattern , a blank control group received ip of equivalent normal saline , the remaining 5 groups received ip of 5mg / kg scopolamine hydrobromide at ihour after last administration . 30mins later , step - down test was used to train mice , the test was given after 24 hour 记忆获得障碍小鼠，在末次给药后1小时，腹腔注射氢漠酸东直著碱sing kg ， 30ndn后使用跳台法训练小鼠， 24 j ’时后重新测试，记录触电潜伏期和5dn内错误次数。
3 . the numbers of lek - immunoreactive neurons in ld and vpm of saccharin intraoral infused group were significantly more than those in control group while the numbers in ld and mdl of licl i . p . injected group were remarkably fewer than those in control group 3 、糖精溶液口腔灌流组大鼠丘脑外侧背核（ ld ）和丘脑腹后内侧核（ wm ）内比k免疫阳性神经元数均显著多于对照组：卜兀1腹腔注射组大鼠的ld和丘脑内侧背核外侧部（ mdl ）内lek免疫阳性神经元数显著少于对照组。
The results showed that : significant increase in dna migration and comet frequency in the spleen , thymus , bone marrow and peripheral lymphocytes were induced after intraperitoneal treatment of mtx at a dose of 1 . 25 ~ 5mg / kg . no obvious increase in dna single strand breaks was observed in the liver , kidney , testicle and stomach of the mice with the same treatment . the migration of nuclear dna and comet frequency of spleen , thymus , bone marrow and peripheral lymphocytes in the dose - response study showed a dose - dependent increase 实验结果：腹腔注射5mg kgmtx后3h可诱发小鼠体内脾细胞、骨髓细胞、胸腺细胞和外周血淋巴细胞的dna单链断裂且随时间延长损伤程度增大，于12h达到高峰，但未观察到对肝、肾、胃和睾丸细胞的山窗民科大学硕士学位论文影响;核dna损伤程度随着用药剂量的增大而增大。
Hwtx - v can reversibly paralyze locusts and cockroaches for several hours with an ed50 value as 16 + 5ug / g to locusts , and larger dose of the toxin can cause death . the neurotoxic symptoms induced by intra - abdominal injection of huwentoxin - v were paralysis , immobilization and last gradually recovery Hwtx -通过腹腔注射，能使蝗虫和蜚蠊产生可逆的剂量依赖性的麻痹作用，麻痹时间长达十多个小时，在高剂量( 100 g g )时可使蝗虫和蜚蠊致死，对蝗虫的ed _ ( 50 ) = 16 5 g g 。
Comparing with controls , the amount and dyeing of immunopositive cells of il - 1 receptor type i in rat paraventricular nucleus of the hypothalamus and the supraoptic nucleus were significantly enhanced by intraperitoneally lps or seb injection ( po . 05 ) , and the dyeing areas and processes of positive cells were enlarged 与对照组比较， lps或seb腹腔注射后大鼠下丘脑室旁核和视上核中表达型il - 1受体的细胞数量显著增加，染色加深( p 0 . 05 ) 。阳性细胞的染色面积增大，突起增长。
Spatial resolution deficit pattern , after administration for 10 days , water maze test was adapted to train mice for successive 5 days . a blank control group received ip of equivalent normal saline , the remaining 5 groups received ip of 15mg / kg pentobarbital sodium at 30min before training everyday , mice were administrated 1 time during training 空间分辨障碍小鼠，连续给药10天后，采用水迷宫法连续训练5天，每天y ！ i练前30ndn ，腹腔注射戊巴比妥钠15mg kg 。训练过程中每天给药1次。
Methods : in the first part , we survived and cultured m4g3 hybridoma in vitro . after two weeks of injecting hybridoma into mouse abdominal cavity , we collected abundant ascites . at the same time , 4 strains of breast cancer cells had been growing in vitro , digested and collected for immunocytochemistry and western blotting with m4g3 ascites 方法：第一部分：复苏m4g3杂交瘤细胞，体外培养，小鼠腹腔注射，进行单克隆抗体的大量制备；复苏t47d等四种乳腺癌细胞，体外培养，爬片，应用m4g3进行免疫细胞化学实验；四种细胞收集，应用m4g3进行western - blot染色。
In order to study immunization of genetic vaccine by inoculation , two kinds of dna vaccine of ndv are constructed and analysed their sequense , which will express f protein in eukaryotic cell ( hela cell ) in vitro with the method of transfection by cationic liposome the results testify that two sorts of plasmids dna successfully expressed the f protein of ndv in hela cell , but the expressed content of pc4 . 0f is higher than ones of pc3 . 1f 将构建的基因疫苗pc3 . 1f大量提取和纯化，采取肌肉注射和腹腔注射两种途径、不同剂量免疫小鼠，用elisa方法检测小鼠血清中抗f基因表达产物的抗体水平。研究结果表明，基因疫苗pc4 . 0f和pc3 . 1f均在hela细胞中成功表达，其中pc4 . 0f的表达量比pc3 . 1f高。
The levels of metallothionein synthesized in liver of the mice induced by different stress factors including trauma , starvation , zinc ( zn ) nutriment , cadmium ( cd ) poison , both zn nutriment and cd poison and different treating ways which were designed according to the time - effect and dosage - effect were detected by atomic absorb mean and sulfydryl saturation mean respectively 用镉饱和法及巯基显色法两种方法检测小白鼠肝脏mt的量，研究不同应激因子诱导小白鼠肝脏mt合成的对应情况，结果表明： 1镉常规毒理实验中，镉对小白鼠腹腔注射的半致死剂量为2 . 12 ( 2 . 67 1 . 71 ) mg / kg 。
