裂殖体

Following 72 h co-culture, desquamate, sporozoites, trophozoites, meronts, microgametocytes, macrogametocytes, zygote, thin-wall oocyst, and thick-wall oocyst appeared orderly. Between the 60th and 72th hour, many oocysts emerged. Inoculated by the C. parvum -infected cell culture supernatant at the 48th hour, the immunosuppressed mice became infected.

在感染后72 h内，隐孢子虫出现连续发育阶段，包括脱囊、子孢子、裂殖子、裂殖体、滋养体、配子体、合子、薄壁卵囊和厚壁卵囊，在60～72 h内形成卵囊；用感染48 h的细胞培养上清接种于免疫抑制小鼠， 10 d后有隐孢子虫卵囊排出。

The life cycle and pathogenicity of E.stigmosa were observed chronologically. There might be only one merogony stage in the life cycle of E.stigmosa. Each meront contained 3-5 merozoites.

结果，在内生性发育过程中，多斑艾美球虫可能仅有1个世代的裂殖生殖阶段，每个裂殖体含3～5个裂殖子。

The mature schizont contains 4-8 merozoites, with one pigment granule, they hardly be observed the cytoplasm, not tend to the pole of host cell and has no"the tie structure"in the mature schizon, the merozoite has no refractive globule.

成熟裂殖体含有4-8个裂殖子，并有一颗恒定的疟色素粒，没有"领带结"结构，裂殖子没有折光球，成熟裂殖体几乎观察不到细胞质。

The effect of tat p53 on the growth of parasites was determined by counting the parasitemia changes between pre and post incubation of the fusion protein with the parasite culture for 12 h. results: tat p53 fusion protein could be transduced into p.f parasites, locating at trophozoit and late schizont stage, whereas p53 protein could not.

结果：tat p53融合蛋白可以突破红内期疟原虫各层细胞膜，进入虫体细胞内，并可根据荧光观察到融合蛋白主要分布在疟原虫滋养体和晚期裂殖体，而p53蛋白不能进入疟原虫内。

One: it parasite in Cuculus canorus, the mature schizont has little cytoplasm, containing 3-6 merozoites which is bar in morphology. The cycle of schizogony is 24 hours, and the synchronicity of development is slight.

该虫寄生于大杜鹃，成熟裂殖体几乎观察不到细胞质，含有3-6个裂殖子，裂殖子为长条形，裂体生殖周期是24小时，但同步性较差。

It is mainly used to control the second-generation schizont of coccidis with the activity peak to coccidis on the forth day.

尼卡巴嗪主要作用于球虫第二代裂殖体，对鸡虫的活性高峰期为第四天，即对第二代裂殖体活性最强。

The mature or nearly mature schizont often was often not observed the cytoplasm.

斑鸠疟原虫无性体也较大，成熟裂殖体一般有20个以上的裂殖子，而且一般观察不到细胞质。

The mature schizont contains 2-6 merozoites, in a same schizont, the merozoites have distinct difference in dimension, the schizonts have no pigment granule, and do not tend to the pole of red cell too. The mature schizonts have little cytoplasm.

成熟裂殖体含有2-6个裂殖子，在同一裂殖体内裂殖子有大小的显著差异，裂殖体不含疟色素粒，裂殖体不趋极且未见到细胞质。

Trophozoite,macrogamout,microgamout, typeⅠmeront,typeⅡmeront and sporozoite in the development of C.andersoni were observed by TEM.The proliferation of C.andersoni was significantly inhibited by 1.25μg/ml NTZ and 0.31μg/ml GAs.Treated with 20μg/ml NTZ and 5μg/ml GAs respectively,the numbers of C.andersoni were only 0.29%and 0.66%compared with the untreated.

透射电镜在HCT-8细胞中观察到安氏隐孢子虫的滋养体、雌配子体、雄配子体、Ⅰ型裂殖体、Ⅱ型裂殖体和子孢子阶段。1.25μg/ml NTZ和0.31μg/ml GAs即可显著抑制HCT-8细胞中安氏隐孢子虫的增殖。20μg/ml NTZ和5μg/ml GAs作用后，虫体数量仅分别为未加药的0.29%和0.66%。

The mature schizont contains 4-8 merozoites, with one pigment granule, they hardly be observed the cytoplasm, not tend to the pole of host cell and has no"the tie structure"in the mature schizon, the merozoite has no refractive globule.

成熟裂殖体含有4-8个裂殖子，并有一颗恒定的疟色素粒，没有&领带结&结构，裂殖子没有折光球，成熟裂殖体几乎观察不到细胞质。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
