The antiparasitic effect of caprylic acid against several fish parasites, i.e., the ciliate Cryptocaryon irritans, monogenean Benedenia seriolae, copepod Pseudocaligus fugu and myxosporean Kudoa shiomitsui, was examined by in vitro trials.Caprylic acid at a concentration of 1 mM had a parasiticidal effect against C. irritans theronts, B. seriolae oncomiracidia and K. shiomitsui spores and a contractile effect against B. seriolae adults, but had no clear effect against P. fugu copepodids and adults.

在体外实验中研究了辛酸对多种鱼类寄生虫的抗虫效果，如纤毛虫刺激隐核虫、单殖吸虫鰤贝尼登虫、桡足类Pseudocaligus fugu和微孢子虫库道虫。1mM的辛酸对刺激隐核虫滋养体、鰤贝尼登虫纤毛幼虫和库道虫孢子具有杀虫效果，对鰤贝尼登虫成虫有收缩效果，但对Pseudocaligus fugu的桡足幼体和成虫无明显效果。

Results A total of 12 587 single ciliated cells could be isolated from nasal epithelium of each guinea pig.

结果 从每只豚鼠的鼻粘膜平均可分离出单离纤毛细胞(12 587±2 437)个。

Both the new peniculus 1 and the old haplokinety separated at the telophase.The two germinal rows germinal rowsfor both the daughter cells appeared almost at the same time;(2) The macronucleus became shorter and thicker, finally oblate during the division of the cell. Then the macronucleus restored its original shape, band-like form. The micronucleus were divided into two before the macronucleus division;(3) The original scopula and stalk contributed to the old cell. The new cell formed scopula gradually after the cell division.

同时，新仔虫的第一咽膜(P′1)也开始由老单毛基索复制，并在细胞分裂后期与老结构分离；(2)大核在虫体分裂过程中由长带状逐渐缩短变粗至扁圆形，于虫体即将分开时迅速拉长，然后分裂为二个新大核；小核分裂先于大核，在两仔虫口纤毛器即将分开时完成；(3)原帚胚及柄归属老仔虫，新仔虫的帚胚在虫体分裂后逐渐形成，柄内肌丝则在柄鞘形成后逐渐长出。

Lastly, based on analysis on phylogentic relationships among 39 ciliates combined with their main morphologic characters, some conclusion were drawn: 1 the monophyly of the peritrichs was strongly supported, and its subclass rank in the class Oligohymenophorea is reasonable; 2 the genus Epistylis might not be monophyletic, and the peristomial area, especially the peristomial lip, might be an important phylogenetic character within the genus Epistylis; 3 the taxonomic rank of the genus Carchesium and the genus Campanella were suggested to be adjusted; 4 Opisthonecta probably diverged from peritrichs with stalks; 5 the phylogenetic tree of peritrichs was reconstructed based on the molecular information inferred from SSrRNA gene sequences and the morphology.

测定了6科8属13种缘毛类纤毛虫的SSrDNA序列，将构建的最大简约树和邻接树与形态学相结合，分析得出：1）缘毛类纤毛虫是单系的，其分类地位是隶属于纤毛门寡膜纲缘毛亚纲：2）指出累枝虫属可能不是单系的，口围区是累枝虫属中重要的系统发育特征；3）建议调整独缩虫和聚钟虫属的分类地位；4）得出后游虫可能是由有柄缘毛类进化而来的类群；5）基于缘毛类反口区结构和SSrRNA基因序列提供的信息重建了缘毛类纤毛虫的系统发育树。

This essay chooses the study aim from biology teachers in middle school in Shi Jiazhuang which tells us that most of the middle school biology teachers in Shi Jiazhuang have the"burnout", lower successfulness, individualize.

本文选取石家庄市初中生物教师作为研究对象，运用问卷调查的方法对石家庄市初中生物教师职业倦怠的现状进行调查，调查结果发现，石家庄市初中生物教师这一群体普遍存在职业倦怠，情感枯竭程度偏高，成就感偏低，去个性化程度最为严重。
