It is similar in structure to αandβ-Asarone that are genetoxic to rat hepatocytes. Carpacin''s isomer, myristicin is not genetoxic to rat hepatocytes and can induce glutathion S-transferase activity that is reported to have effect in rat hepatocytes.

其类似物α与β-Asarone对鼠肝细胞具有基因毒性及其异构物myristicin对鼠肝细胞并无基因毒性，且可诱发出glutathion S-transferase等解毒酵素的活性。

Among the fish which were cytogenetically studied, most of them do not possess any morphologically differentiated sex chromosomes. On the other hand, karyotypic analysis, chromosome binding, synaptonemal complex observation and comparative genomic hybridization show in few fish species, that there exist sex chromosomes which differentiated at different levels and types.

在进行过细胞遗传学研究的鱼类中，绝大部分没有发现异形性染色体，然而通过核型分析、染色体显带、联会复合体观察和比较基因组杂交等方法，发现在少部分鱼类中确实存在有异形分化的性染色体，并且分化程度高低不等，性别决定方式多种多样。

In the studies on transferring and identifying alien chro-mosomes into wheat,the combined use of mitotic and meioticchromosome N-banding is also successfully practiced in deter-mination of T.durum-H.villosa amphipoid,five wheatalien disomic additions with H.villosa chromosomes,〓〓,alien sulstitution line with chromosome 〓 andsome translocation lines.

在外源染色体导入、鉴定研究中，利用根尖有丝分裂中期染色体和花粉母细胞减数分裂中期Ⅰ染色体的N-分带，快速、准确地鉴定了硬粒小麦一簇毛麦双二倍体、普通小麦一簇毛麦异耐加系V〓、V〓、V〓、V〓和V〓，普通小麦一簇毛麦异代换系V〓以及一些具有易位的杂种后代。

Methods The exfoliated cells from 84 cases hydrothorax and ascites(including 35 cases of malignant tumor group and 49 cases of non-tumor group) were analyzed in DNA ploid by FCM, the results were compared with the method of exfoliative cytology.

方法应用流式细胞仪对84例患者(恶性肿瘤组35例，非恶性肿瘤组49例)的胸腹水脱落细胞进行DNA倍体分析；以检出异倍体为恶性肿瘤判断标准，并与胸腹水常规脱落细胞学涂片检查结果比较。

Induction of isotypic heterostrain antibody (Ab1): BALB/c mice were immunized with C57BL/6 splenocytes to raise antibody (Ab1) between the two difference strains.

抗同种异品系抗体(Ab1)的诱导 C57BL／6小鼠作为移植供体，BALB／c小鼠作为受体。取C57BL／6小鼠的脾细胞免疫BALB／c小鼠，制备抗同种异品系抗体(Ab1)。

The clinical features included peripheral lymphadenopathy and skin lesions, recurrent fever was very common. the pathological features included partial lymphomatous involvement of lymph node, sheets of analplastic large cells infiltrated the sinuses and paracortices, immunohistochemical cd30 was strongly positive. the prognosis was comparative well.

结果：间变性大细胞性淋巴瘤占小儿非霍奇金淋巴瘤的12.8%，临床表现主要是外周淋巴结肿大及皮肤损害，长期反复发热常见，病理特征为淋巴结部分受累，成片异形大细胞侵犯淋巴窦及副皮质区，免疫组化cd30强阳性，预后相对较好。

Based on these characteristics observed, species in Pteridaceae tended to accumulate and deposit silica in long cells in lower epidermis and forming spicular cells. This might helps them to enhance the supporting function of their lateral veins.

综合以上特徵推测，凤尾蕨科倾向将二氧化矽堆积於叶下表皮与叶脉平行之表皮细胞上，并形成矽异形细胞，该特徵可能与加强叶片的支持力有关。

Objective To investigate which stage is the most important and the relationship with kupffer cell,during isoflurane decrease anoxia-reoxygenation injury in isolated rat liver.

In order to elucidate the regulation mechanism of RU5 region to BFV gene expression, BFV3026 provirus DNA was used to construct the plasmids containing different deletion of R region, which were cotransfected with luc report gene locatied behind the IP promoter to BL12 cells, and luciferase activities was assayed, confirming that U5 region could repress the initiation function of LTR as well as IP. The BFV structure genes with different deletion of R region were cloned closely behind to heterogenous CMV promoter, then transfected to 293T cells, RT activity was performed, testifying the R region was required for BFV pol gene expression, and also the function domain was identified within the 100n.t. sequence at the 5′end.

以牛泡沫病毒(Bovine foamy virus， BFV)中国株BFV3026原病毒DNA为材料，构建R区系列缺失质粒，通过对其转染细胞中RT水平及对缺失质粒与luc报告质粒共转染细胞中萤火虫荧光素酶活性的测定，确立U5区对于BFV3026两类启动子LTR和IP均具有负调控作用；同时将带有不同R区的BFV3026结构基因片段克隆于异源启动子CMV之下，通过对其转染细胞293T中RT酶活性的测定，确立R区对于病毒结构基因pol的表达具有一定的调节作用，并将其功能区域初步界定在R区5′端100bp内。

Pica, different food is also common symptoms of zinc deficiency in children, due to zinc deficiency, the tongue's taste buds cell regeneration occurred obstacles, taste Su-lowering, taste weakened.

异食癖，异食也是小儿缺锌的常见症状，由于缺锌，舌的味蕾细胞再生发生障碍，味觉素降低，味觉减弱。

The split between the two groups can hardly be papered over.
