RESULT ①Two different ITS2 sequences (GenBank accession number: AF416783, AF416784) and D3 sequences (AF416782, AF415594), named as An. minimus A and An. minimus C, were detected in this study. They differed by 5. 8％ in the ITS2 region with 22 fixed nucleotide substitutions and indels, and by 1. 5％ in D3 gene with 5 site mutations. There exists individual variation in the COII gene, but this variation is less than that among other members of Myzomyia Series such as An.

结果 ①分别发现两种不同的ITS2序列（GeneBank登录号：AF416783，AF416784）和D3序列（GeneBank登录号：AF416782，AF425594），与微小按蚊A和C同源。A、C两者ITS2序列22个固定位点存在碱基置换和插入／缺失，序列差异为4.8％；D3基因存在5个固定点突变，突变率1.5％。mtDNA-COII基因存在个体差异，但远小于同系其它成员如乌头按蚊、杰普尔按蚊间的变异。

Rabies virus, the etiologic agent of fatal neurological disease, is composed of five stuctural proteins, both of the glycoprotein and the nucleoprotein are believed the decisive factors for rabies diagnosis and classification and for rabies neurotropic, pathogenicity and antigenecity.

狂犬病毒由五种结构蛋白组成，其中NP对狂犬病的诊断和分类；GP对狂犬病毒的组织嗜性、致病和免疫保护都起着决定性的作用，并且分离自不同宿主或不同地理位置的狂犬病毒之间存在着NP和GP抗原性差异，研究这种差异并结合流行病学资料有助于发现流行来源的线索。

In order to clarify the genetic mechanism of the adhesion,an in vitro adhesion experiment was carried out for three variants of E.coli F4in 366 piglets of three pig breeds.The results showed that there existed significant differences(P.001)in the adhesion percentage among the three breeds.Most SB piglets were nonadhesive for all the three variants,whereas most LR piglets were adhesive.Within each breed except for LR,the proportions of the three F4 variants adhering to the brush borders differed significantly.

为了研究黏附的遗传机制，本实验利用大白、长白、松辽黑猪的小肠刷状缘细胞与F4ab、F4ac、F4ad进行离体黏附实验，结果发现3品种猪之间黏附情况存在显著差别(P《0.01)，松辽黑猪以非黏附型为主，而长白猪中黏附型比例较高，在同一品种猪内，3种菌株的黏附比例在松辽黑猪内和大白猪内有极显著差异，但在长白猪中无显著差异。

All kinds of these study results, including analyzing the nucleotide composition, the amino acid composition, the nucleotide diversity, the synonymous and the nonsynonymous, the transition and the transvertion, the frequencies of the codon used, the construction (including four stems and four loops) of tRNAleu,the phylogeny,suggest that great distinctness present among the genera and small difference even none among species.

在各种分析中(包括核苷酸基本组成分析；氨基酸基本组成分析；核苷酸多样性分析；非同义替代和同义替代分析；密码子使用频率分析；转换与颠换分析；tRNAleu基因的四臂四环二级结构分析；&翻译启始&和&翻译终止&在进化过程中的变化；系统发育分析)，属间的差异相当明显，而种间差异很小甚至是没有任何不同之处。

The mate choice of Brandt′s voles Microtus brandti was investigated in the laboratory to study the mating system of this species. It was found that the female voles spent significantly more time visiting the partners than the strange males, but the male voles did not show any preference of the partners to the strange females. A female vole showed no difference in the copulatory behavior between an unfamiliar male and a familiar male which had copulated with her for 15 minutes, but she visited and fought the unfamiliar male significantly more than the familiar male. A male vole significantly preferred visiting and mating with an unfamiliar oestrous female to a familiar female which had copulated with him for 15 minutes.

在实验室通过布氏田鼠对配偶与陌生异性鼠、已交配和未交配异性鼠、熟悉和陌生异性鼠三种情况下配偶选择的实验研究，结果表明：雌性布氏田鼠对配偶的选择显著地要多于陌生雄鼠；虽然对陌生和熟悉雄鼠选择差异不显著，但对陌生鼠的选择强度要高于熟悉雄鼠；同时对已交配和未交配雄鼠的选择无显著差异。

Except NO2--N, significant difference of the outcoming concentration cannot be found between the control and the three species of mangroves treatment groups.

除NO3--N和NO2--N，对照池与红树植物处理组之间存在显著的差异，其余指标对照池与3 种红树植物处理组之间不存在显著差异。

CustomcDNA array筛选的8000个cDNA克隆中有47个在去神经30天海马显示差异表达且表达变化在3倍以上，其中25个表达上调，22个表达下调；Northernblot实验表明cDNA array的假阳性率是较高的。cDNA microarray在大鼠中枢神经系统表达的6234种基因和EST序列中，筛选到了152个基因和EST序列在去神经10天海马差异表达，表达变化在1.5-2.8倍之间，其中表达上调的32个，下调的120个。

Of 8000 cDNA elements, custom cDNA array identified 47 as differentially expressed genes/ESTs with above 3-fold changes in the hippocampus 35 days after lesion, in which 25 were up-regulated and 22 down-regulated. Northern blot hybridization indicates that false ratio is high with the cDNA array experiment. Of 6234 rat CNS genes/ESTs, cDNA microarray identified 152 as differentially expressed cDNA clones with changes between 1.5-2.8 fold in the hippocampus 10 days following perforant path injury, 32 were up-regulated and 152 down-regulated.
