As it often happens with stressed fish, a massive infestation by a trichodina ectoparasite was observed in medaka from imidacloprid fields.

因为经常处于紧张状态，使用imidacloprid鱼塘的青鳉受到车轮虫的大面积感染。

The degradation of PAHs at 0.03, 0.3, and 3 mg/g soil, either added singly or as mixtures, were evaluated for their evolved CO2 in Biometer flasks. The contaminated soil was later Soxhlet extracted with hexane. The extracts were evaporated, redissolved in dimethyl sulfoxide, and subjected for Microtox assay and Medaka embryo toxicity test. The evolved CO2 from singly PAHs addition was correlated with concentration gradient.

根据结果显示，受单一PAHs污染土壤之降解量，以CO2累积量表示，两环之Naphthalene其降解量为最多，在低浓度0.03 mg PAHs/g soil时，有所谓的诱引作用产生；受混合PAHs污染土壤之降解量，以Naphthalene对於Phenanthrene的刺激作用为最大；在复育实验方面，以添加苯酸之CO2累积量为最高，单就界面活性剂而言，则以Tween 80的表现为最佳。

Three organochlorine pesticides -endrin, dieldrin, and p,p'-DDT-were used as target compounds to test the hypothesis that triolein embedded cellulose acetate membrane only extracts freely dissolved hydrophobic organic compounds. The effect of dissolved organic carbon on the bioavailability of the OCPs was also examined through accumulation study with TECAM and Japanese medaka.

以异狄氏剂、狄氏剂和p，p'-滴滴涕3种持久性有机氯农药为研究对象，通过室内模拟实验，验证了三油酸甘油脂-醋酸纤维素复合膜富集水中自由溶解态疏水性有机物的假设，研究了水中溶解性有机碳对TECAM富集3种有机氯农药的影响，并与相同暴露条件下日本青鳉鱼的富集结果进行了比较。

The zebrafish Gel shows 31, 73, 71, and 85% similarity to Drosophila, mouse, human and medaka Gel protein respectively.

序列对比表明：斑马鱼Gcl蛋白与果蝇、鼠、人、青鳉鱼Gcl蛋白的序列相似性分别为31、73、71、85%。

Furthermore, their transparent embryos allow one to easily observe the green fluorescent protein expressed in GFP-transgenic medaka during development.

此外，青鱂鱼卵是透明的，可以在绿萤光转殖青鱂鱼的鱼卵发育过程中，观察绿色萤光产生的时间，以及发出绿色萤光的细胞与组织。

These findings strongly suggest that the sex-specific DMY is required for testicular development and is a prime candidate for the medaka sexdetermining gene.

这些发现足以说明DMY基因，是精巢发育所必需并且是青鳉鱼性别决定的重要候选基因。

Results showed that TECAM only extracted the freely dissolved HOCs and the presence of DOC in water reduced the availability of HOCs to both TECAM and Japanese medaka. The effect of DOC on the accumulation profiles of the three target compounds in TECAM and medaka was similar.

结果表明，TECAM只富集水中自由溶解形态的疏水性有机物；水中存在的溶解性有机碳会降低3种有机氯农药被TECAM和青鳉富集的可利用性；TECAM和青鳉的富集结果有很好的可比性。

The fourth generation of transgenic medaka,inbred variety,was obtained by heterozygote (F2 and F3) breeding of two generations and homozygote (F4) breeding of one generation based on mosaic (F1) of transgenic medaka.

对嵌合体的转基因青鳉（F1）进行了两代的杂合体（F2和F3）筛选和一代的纯合体（F4）筛选，获得第4代转基因青鳉纯系品种。

During remediation experiment, the addition of benzene acid and Tween 80 gave higher CO2 evolution. The result of Microtox assay showed good correlation between aromatic rings of PAHs at low concentration. The Medaka embryo toxicity test had presented that while eggs were exposed to the soil extracts from fluoranthene and pyrene at high concentration (3mg PAHs/g soil), the embryo showed low hatch ratio、bleeding, high abnormal ratio and delayed mature period. The addition of composting materials for remediation study showed strong embryo toxicity to Medaka embryo at all test concentration.

青鱂鱼鱼卵试验部分，受单一与混合PAHs污染土壤之萃取物对青鱂鱼鱼卵孵化影响，当暴露在浓度3 mg PAHs /g soil时，及四环的Fluoranthene与Pyrene之下，皆有高未孵化率、高出血率、高畸形率及孵化天数的延迟现象产生；而在复育实验之土壤萃取物对青鱂鱼鱼卵孵化之影响，以添加酸性界面活性剂与中性界面活性剂实验组其鱼卵之未孵化率皆为零，与Microtox毒性测试结果有良好的关连；加入不同复育添加剂中，则以添加菜肥之实验组，对於青鱂鱼鱼卵孵化之影响为最大。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。
