血疟原虫

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。

Results plasmodium falciparum were detected from smears of 65 baby and infant falciparum malaria cases. clinical manifestations were fever (100%), vomiting in 32 cases (49.2%), diarrhea in 23 cases (36.9%), cough in 27 cases (41.5%), convulsions in 12 cases (18.5%), disturbance of consciousness in 19 cases (29. 1%), anemia in 52 cases (80.0%), splenomegaly in 46 cases (71.6%), hepatomegaly in 41 cases (63.1%), meningeal thorn forward levy in 19 cases (29. l%). sixty patients cured after treated wth artesunate and 5 cases died.

结果 65例恶性疟疾婴幼儿的血涂片均见到恶性疟原虫；临床表现以发热(100%)，呕吐32例(49.2%)，腹泻23例(36.9%)，咳嗽27例(41.5%)，抽搐12例(18.5%)，意识障碍19例(29.1%)，贫血52例(80.0 %)，脾肿大46例(71.6%)，肝肿大41例(63.1%)，脑膜刺激征19例(29.1%)。65例均接受青蒿琥酯抗疟的综合治疗，治愈60例，死亡5例。

Two patients had a recrudescence 21 and 25 days respectively after the disappearance of parasitemia, hence the recrudescence rate was 3.7%and the cure rate was 96.3%.

平均退热时间为21.2±2.8小时，54例中2例在疟原虫血症消失后第21、25天复燃，复燃率3.7%；治愈率96.3%。

The levels of nitric oxide and interferon-γ in spleen cell cultured supcrnatants of 3 kinds of infected mice were measured by using ELISA kit and Griess reaction. Results: On the 3rd day after infection, the parasitemia of DBA/2 mice was much lower than that of BALB/c and C57BL/6 mice.

结果：感染第3d之后，DBA／2小鼠的虫体血症水平显著低于BALB／c和C57BL／6小鼠；将疟原虫寄生的红细胞和脂多糖或IFN-γ分别与3种感染第3d小鼠脾细胞共同培养后，DBA／2小鼠脾细胞培养上清中的IFN-γ和NO水平明显高于BALB／c和C57BL／6小鼠。

The blood smear showed 5% parasitemia of red blood cells with Plasmodium falciparum.

血涂片显示5%红细胞受染恶性疟原虫 Plasmodium falciparum 。

Challenge was made after one month of immunization by vein. Re sults:The parasitemia of recombinant virus immunized monkey was 0.0 1%in first tw o days of post-challenge. No parasites were determined from third to 12th day. W hereas the parasitemia of control virus immunized-monkey and blank control monk ey rose progressively,went to 2.5%～6.0% at 6th～8th days of post-challenge, an d the t ime of parasitemia was 12～13 days.

结果： 在免疫后1个月攻虫，重组痘苗病毒免疫猴从第3天一直到第12 d的采血检查中均未发现疟原虫；非重组痘苗病毒免疫猴第3天后原虫感染率上升，第6天原虫感染率最高达到6.0%，而后原虫感染率逐渐下降，原虫持续时间为13天；空白对照猴第3天后原虫感染率也上升，第8天原虫感染率最高达到2.5%，而后原虫感染率逐渐下降，原虫持续出现时间为12 d。

Using the method of edge and gray scale detection, the Plasmodium vivax schizont can be detected and identified.

初步探索采用边缘和图像灰度联合检测的方法能够识别间日疟原虫薄血膜的裂殖体。

Methods We processed the image of thin smear film of the Plasmodium vivax schizont through several steps including image preprocessing, image segmentation and feature extraction. The recognition rate and accuracy were observed.

基于图像预处理、图像分割、特征提取、判决分类等步骤，分别对间日疟原虫薄血膜的裂殖体图像进行处理，观察其识别效率和准确度。

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。

Monkey or human volunteers. Methods: The multiple partialy replacement transfused hum an blood macaca monkey mo dels were used.

利用多次部分换人血猕猴模经静脉输血法进行了抗疟原虫红内期虫体的攻击试验。
