目的 研究蒿甲醚与瑞香素伍用对感染伯氏疟原虫ANKA株小鼠的疗效及其联合作用方式。

Objective To investigate the effect of artesunate on the development of Plasmodium cynomolgi in anopheles dints and prevention against malaria.

目的 观察青蒿琥酯对食蟹猴疟原虫在大劣按蚊体内发育的影响。

Malaria is caused by a parasite called plasmodium, which is transmitted via the bites of infected anopheles mosquitoes.

疟疾是由疟原虫引起，通过蚊虫叮咬传播的寄生虫病。

According to the malaria statistics in 1989,the number of malaria cases,malaria incidence and positive parasite rate in native resident fever cases,and the number of malaria loci decreased by 20%,21.79%,35.85% and 31.06% respectively in comparison With that in 1988·In addition,the malaria transmission peak dropped down·All these achievements are due to strengthened antimalaria measures,especially in the areas where malaria incidence was higher.

1989年全省疟疾发病人数，发病率，当地发热病人血检疟原虫阳性率和疟疾病灶点数分别比1988年下降20.4%、21.79%、35.85%和31.06%，压低了9月份的发病高峰。

T helper cell subsets play an important role in antimalarial immunoregulation in mice.

但在攻击感染疟原虫后Th2型细胞被提前激活而抑制了Th1型细胞的正常功能，最终仍导致小鼠死亡。

The so-called transgenic insects would be resistant to infection by falciparum.

这种所谓的转基因昆虫可能会对疟原虫产生抗体。

Objective To analyze humoral immune response to nucleic acid vaccines (VR1012/TPA/HG-MSP1-17 for intracellular expression or VR1012/HG-MSP1-17 for secretion) which contain Plasmodium falciparum Merozoite surface protein 1(MSP1) 17 block gene and gene fragment of several T cell epitopes from MSA1, MSA2, RESA, IL-1 and TT and to monitor the effect of DNA-immune sera on parasite inhibition.

摘 要：目的检测以恶性疟原虫裂殖子表面蛋白1的17区片段基因为基础的复合核酸疫苗(分泌性的VR1012/TPA/HG-MSP1-17和非分泌性的VR1012/HG-MSP1-17)诱导小鼠的体液免疫反应和免疫血清对疟原虫生长的抑制能力。

Dr Marrelli and colleagues had already shown in preious experiments that transgenic anopheline mosquitoes would not pick up the Plasmodium (in this case, they used the species P. berghei) when fed on infected mice.

Marrelli博士和他的同事们在以前的试验中就证明了转基因的按蚊在吸食受感染老鼠的血液时不会携带疟原虫（在这项研究中，他们使用的是伯氏疟原虫）。

The pre erythrocytic stage vaccines aim to prevent the development of all clinical symptoms and subsequent malaria transmission. Erythrocytic stage vaccine designed aims to induce antibodies that prevent invasion and infection of erythrocytes, to reduce morbidity and mortality by decreasing the parasite load.

作用于红细胞前期的疟疾疫苗主要是抑制疟疾的临床发作，控制疟疾的传播；作用于红细胞期的疟疾疫苗诱导宿主体液免疫系统，产生特异性抗体，抑制疟原虫侵入和感染红细胞，达到减少疟原虫虫荷，降低疟疾的发病率和死亡率。

When she jabs her proboscis into a person's epidermis to drink blood, she sprays the bite area with saliva that serves as an anticoagulant. If her last victim had malaria, that saliva will contain one-celled malaria parasites called plasmodia, a couple of dozen of which can enter the human bloodstream. But it only takes one to kill a person.

当按蚊的雌蚊猛刺进人的皮肤吸血时，还会喷射抗凝剂，假如它叮咬的是患有疟疾的病人，那么雌蚊也就把疟原虫吸进它的体内，然后她又去叮咬其它的人，又把雌蚊体内的疟原虫传播到另外的人造成新的疟疾病人。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
