Observations on pathological and histochemical changes in piglet livers infected with Taenia saginata asiatica

To study the pathological and histochemical characteristics of lesions in piglet livers infected with Taenia saginata asiatica (T. saginata asiatica) throughout the different stages, piglets were fed with eggs of T. saginata asiatica and raised in isolation in an animal center to establish the T. saginata asiatica infection model with normal piglets as control. The pathological changes in the piglet livers were observed after the infection using liver sections stained with hematoxylin and eosin. Histochemical methods were used to check the changes in lipid, glycogen and protein content in the liver. The data collected by image analysis were analyzed statistically with Statistical Package for the Social Science. The results show that T. saginata asiatica-exposed piglets were indeed infected. Inflammatory reactions began on the fourth day and progressed rapidly. Kupffer cell hyperplasia, hepatic hydropic degeneration and ballooning degeneration were found in the 10th–20th days after infection. Hepatic central veins and hepatic sinusoids were dilated and congested. Spotty necrosis occurred in some local liver tissues. In the 40th–60th days, granulomatous reactions and mild hepatocirrhosis were the main lesions. In the 70th–80th days, hepatocirrhosis and bile duct proliferation were observed in the liver. In the different stages, lipid drops were increased while glycogen and protein levels were decreased to some degree. There was a significant difference in metabolism between the infected group and the control group (P < 0.01). It is concluded that pigs are the favorable intermediate host of T. saginata asiatica and its infection can result in serious pathological and histochemical lesions in host organs.

改良输液网及输液流程在临床输液中的应用

静脉输液治疗因其疗效快、刺激性小等优点,在抢救、治疗病人过程中发挥着非常重要的作用,故在护理工作中应用最为广泛[1]。其操作时间受多种因素影响,传统方法操作存在一次排气不成功、微量气泡残留等问题[1,2]。从2005年10月起对输液网进行了改良,并简化了输液流程,经10个月70     

EGF对急性胰腺炎大鼠肠道细胞凋亡的影响

目的:探讨表皮生长因子(EGF)对急性胰腺炎(AP)大鼠肠道细胞凋亡影响的机理。方法:72只雄性SD大鼠AP模型随机分为3组:对照组(仅开腹翻动胰腺,n=24)、AP组(n=24)及APEGF组(n=24)。APEGF组皮下注射EGF0.1μg·g-1,其余两组动物皮下注射相同体积的生理盐水。每次8只大鼠分别于术后6h、12h、24h剖杀取材,经心脏取血2ml,采用全自动生化分析仪检测血清淀粉酶,以干纱布吸沾腹水法测量腹水量。从屈氏韧带远侧10cm处开始取2cm空肠,观测空肠组织细胞凋亡;另取10cm空肠,检测空肠粘膜MDA(丙二醛)含量。结果:术后12h及24h,APEGF组动物腹水量显著低于AP组(P<0.05,P<0.01),APEGF组动物血清淀粉酶也显著低于AP组(P<0.05,P<0.01);术后24h,APEGF组动物血浆、空肠组织MDA含量均显著低于AP组;术后12h及24h,空肠粘膜凋亡指数显著低于AP组。结论:EGF能迅速恢复血清淀粉酶正常活性,降低AP大鼠血浆、肠粘膜组织MDA含量,减轻AP所致的肠粘膜细胞凋亡损害。     

医药团结合作 建设放心药房

总结了全国放心药店现场交流会后,全国各地放心药房建设的情况。强调了建设放心药房工作的意义,指出建设放心药房是中医医疗机构精神文明建设的重要部分,是落实中央指示,加强药品管理的具体行动,是加强中医医疗机构内涵建设的重要内容,是保证中医医疗质量的关键环节。对进一步做好放心药房建设工作提出了要求:规范进货行为,把好药品进货关;不断深化改革,加强内部管理;认真贯彻国家有关法规,继续整治药品回扣违法行为;加强医药团结合作,建立稳定的供需关系;加强领导,务求实效,使“放心药房”建设深入持久地开展下去。

Copolymerization of propene with 1-alkenes using a MgCl2/TiCl4 catalyst

Copolymerization of propylene

1 System name: propene.

and 1-alkenes (1-octene, 1-decene, 1-dodecene, 1-tetradecene, 1-hexadecene) were studied with the catalyst system MgCl₂/TiCl₄-Al(i-Bu)₃. It was found that the polymerization productivity and the consumption rate of propylene are improved significantly in the presence of the comonomer. The total productivity of propylene/1-alkene copolymerizations decreases as follows: 1-octene > 1-decene > 1-dodecene > 1-hexadecene > 1-tetradecene. The reactivity ratios were estimated from the copolymerization results.
