Peroxidase isozymes in the flower ovary and stigma of Ipomoea trifida at different development stages were detected respectively by means of polyacrylamide gel electrophoresis. The development of macrospore, the formation of embryo sac and the differentiation of stigma mammilliform cell were observed under optical microscope and scanning electron microscope.

Peroxidase isozymes in the flower ovary and stigma of Ipomoea trifida at different development stages were detected respectively by means of polyacrylamide gel electrophoresis. The development of macrospore, the formation of embryo sac and the differentiation of stigma mammilliform cell were observed under optical microscope and scanning electron microscope. The results of experiments showed that peroxidase isozymes related closely with the development of macrospore, the formation of embryo sac and the differentiation of stigma mammilliform cell. The variation of peroxidase isozymograms showed a certain specificity of organ (tissue) and development stage. Finally, the relationship between the change of peroxidase isozyme activity and the formation of organ, growth and differentiation of cell during the plant development process was also discussed.

采用聚丙烯酰胺凝胶电泳,分别测定甘薯(Jpomoea trifida)花、子房、柱头在不同发育时期的过氧化物酶同工酶;通过光学显微镜和扫描电镜,观察大孢子的发生、胚囊的形成以及柱头乳头细胞的分化过程。实验结果表明,过氧化物酶同工酶与大孢子发生、胚囊形成以及柱头乳头细胞的分化过程有密切的关系;过氧化物酶同工酶谱的变化具有器官(组织)和发育阶段的特异性。本文还对过氧化物酶同工酶的活性变化与植物发育过程中器官的形成、细胞的生长及分化的关系进行了讨论。

Brugia malayi larvae in artificially infected Anopheles sinensis were detected by using 1G 1,1H 1 McAb selected from several strains of McAb against target antigens of infective larvae. After the mosquitoes were fed with rabbit blood positive for Brugia malayi microfilariae,they were dissected and tested by ELISA and Dot ELISA with labelled monoclonal antibody respectively at different intervals during the feeding period. The results showed that positive rate of filarial larvae was 86.6% by artificial...

Brugia malayi larvae in artificially infected Anopheles sinensis were detected by using 1G 1,1H 1 McAb selected from several strains of McAb against target antigens of infective larvae. After the mosquitoes were fed with rabbit blood positive for Brugia malayi microfilariae,they were dissected and tested by ELISA and Dot ELISA with labelled monoclonal antibody respectively at different intervals during the feeding period. The results showed that positive rate of filarial larvae was 86.6% by artificial dissection, 82.2% and 77.8% by ELISA and Dot ELISA with the sensitivity of 0.5 larva/per mosquito 9 days after mosquitoes were infected. There was no significant statistical difference between the two methods( P >0.05). It also showed that this McAb has a certain specificity. No cross reaction with Setaria digitats and Metastrongylusapri was found.

以马来丝虫感染期幼虫为靶抗原制备多株单克隆抗体(McAb)从中筛选出1G1、1H1单克隆抗体,检测人工感染马来丝虫的中华按蚊。当中华按蚊吸食含马来微丝蚴的兔血后,分别解剖,同时以ELISA及Dot-ELISA检测饲养不同时间的中华按蚊。结果显示,饲养9d的按蚊马来丝虫幼虫阳性率,人工解剖为86.6%,ELISA和Dot-ELISA法分别为82.2%和77.8%。经统计学处理,人工解剖与单抗检测无显著性差异,其灵敏度为每只蚊0.5条幼虫。实验证明,此McAb与牛腹腔指状丝虫、猪肺丝虫抗原无交叉反应,显示了一定的特异性。

Objective To explore the ultrasound and CT diagnosing value for live alveolar hydatid diseas.Methods Twenty three cases of liver alveolar hydatid disease were examined by B ultrasound,routine CT scanning and necessary enhanced scanning.Results Of 23 cases,there were 10 massive shape,3 node shape,6 liquefied necrosis,5 mixed shape.Ultrasonographic findings showed localized of diffused liver tumfaction,the boundary between the tumor and surrounding tissure was not clear or the outer of the tumor was irregular and conveoconcave with cauliflower like shape,the inside of the tumor was of irregular node shape,small vesicular shape or spot and grain shape,small piece shape with calcific focal echo,focal necrosis region,and irregular parietal echo enhanced.CT findings showed that tissue density in pathological region was quite heterogeneous,the inside of which had psoriasis calcified foci,the center of which was necrotic and liquefied cavity with watery density,around which “dizzy shadowsign” was seen.Conclusions Examining by CT enhanced scanning has a positive value to alveolar hydatid disease,and examining by ultrasound is easy to operate,very sensitive and has a certain specificity,which is the first chosen examining method to liver alveolar hydatid disease.

目的 探讨超声与CT对肝泡球蚴病的诊断价值。方法 对23例肝泡球蚴病进行B型超声检查和普通CT扫描,必要时增强扫描。结果 23例中巨块型10例,结节型2例,坏死、液化型6例,混合型5例。超声表现为肝脏局限性或弥漫性肿大,肿块与周围组织境界不清或外形不规整,凹凸不平呈“菜花”状,内部显示不均匀结节状、小囊状或点粒状、小片状钙化灶回声,病灶坏死区腔壁不规整,回声增强。CT的主要特征为病变部位组织密度严重不均匀,其内显示斑片状钙化灶,病变中心坏死腔液化呈水样密度,周边见“晕影征”。结论 CT增强扫描对泡球蚴病有肯定价值,超声检查操作方便,敏感性高,有一定特异性,不失为该病的首选检查方法
