血吸虫病

There are 2 main pathways by which schistosomes cause NS: egg embolism and worm migration, via either artery or vein system, especially the valveless perivertebral Batson's plexus. The adult worm migrates anomalously through the above pathways to the CNS where they lay eggs.

关于中枢神经系统血吸虫病虫卵入侵途径，目前主要存在虫卵栓塞和成虫产卵两种学说，前者分为动脉栓塞、静脉栓塞和Batson椎静脉途径，成虫亦可循上述途径入侵中枢神经系统产卵。

He says the Schistosoma parasite needs oxygen to survive.

他说血吸虫病寄生虫需要在氧气生存。

T cell subsets of peripheral blood lymphocyte were studied in 21 splenomegalia patientswith advanced schistosomiasis japonica,24 splenectiomized patients with AS,and 20 normal persons.The results showed that the rates of CD_4￣+,CD_3￣+ and ratio of CD_4￣+/CD_8￣+were significantly decreased in both groups of patients,as compared with thecontrols.

21例晚期血吸虫病巨脾型患者和24例切脾患者、20例正常人外周血T细胞亚群检测结果表明：晚血患者两组CD_3~＋、CD_4~＋细胞百分率及CD_4~＋／CD_8~＋比值显著低于正常人（P＜0.01），巨脾组与切脾组CD_3~＋、CD_4~＋、CD_8~＋细胞百分率和CD_4~＋／CD_8~＋比值差异无显著性（P＞0.05）。

Effect of oral administration of single subcurative dose (300 mg/kg) of pyquiton on the tegumental surface of adult schistosoma japonicum were studied using scanning electron microscope.

给感染血吸虫病的小鼠一次灌胃吡喹酮300 mg/kg后10分钟至48小时，自鼠肝内取虫作体表皮层扫描电镜观察。

Antimony tri-dodecyl mercaptide was easily obtained from dodecyl mercaptan and antimony trichloride in methanol.

經对感染日本血吸虫病的动物疗效試驗，証明有作用，其毒性以三銻为低。

Objective: To find out the major antigenic molecules of radiation-attenuated cercariae, and provide some useful candidate antigens for developing schistosomiasis vaccine.

目的：寻找照射致弱尾蚴中起免疫保护作用的抗原分子，为血吸虫病疫苗研究提供新的候选抗原。

Objective To study a scientific and useful information network system for the instituting of schistosomiasis control.

目的 为血防部门研制科学、实用的血吸虫病防治信息网络系统。

In the colons of infected mice, IL-4,IL-5 and IL-10 slowly increased with prolongated infection time. Conclusion In the mice infected by schistosome japonicum, the immune response of Th2 related cytokines took place mainly in the liver. The spleen played a role of immune regulation.

感染日本血吸虫病的小鼠，肝脏是Th2相关因子免疫应答的主要器官；脾脏是调节免疫的器官；而结肠Th2相关因子的升高可能是整体反应的一部分。

Results Immunostaining of cNOS and iNOS were negative in the rectums of normal rabbits, whereas the results in the of rabbits infected with S. japonicum were strong positive. The positive immunostaining of cNOS was observed in mucosal capillaries and submucosal vessels. Besides in capillaries and submucosal vessels the positive immunostaining of iNOS was seen in schistosoma ova, ova granuloma, fibroconnective tissue and suppuratie cells.

结果 正常兔直肠壁cNOS和iNOS呈阴性反应，血吸虫病兔直肠壁为强阳性，cNOS主要分布在粘膜毛细血管和粘膜下血管壁；iNOS不仅见于上述血管壁，而且见于虫卵、虫卵肉芽肿周围、纤维结缔组织中、炎性细胞之间。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
