The morphological change alleviated and GFAP expression keeping high in astrocytes at 72h after cerebral ischemia. The results of cell culture show that IL-8 would increase the number of astrocytes and do not scathe neurons.

脑缺血后72hAS表达GFAP仍高同时脑组织中IL-8水平升高，并伴随受损神经元修复；说明GFAP表达及IL-8可能在神经元的抗损伤中具有作用。

In the scatter diagram for PC1 and PC2, 6 (1/3) individuals with intermediate morphologies were located in the contact zone between C. mollissima and C. henryi, which may provide morphological evidence for hybridization between C. mollissima and C. henryi.

前2个主成分的散布图中，有6个(1/3)中间型个体位于板栗和锥栗的重叠分布区域，可能是二者之间存在杂交的表型证据。

Principle component analysis revealed that ten populations were almost overlapped each other in scatter diagram of PC1 and PC2, indicating small morphological variations among ten populations.

提示天津厚蟹和侧足厚蟹有可能交配并产生后代，从另一个方面表明，天津厚蟹和侧足厚蟹可能是同一个物种。

Scatter diagram of the morphological differential value and molecular differential value shows plants molecular differential value≥2 are heterotipe. The correlation coefficient of the morpha uniformity ratio and molecule uniformity ratio is 0.98, extreme correlation. So the heterotipe criterion of the molecular differential value≥2 is made.

通过对14个品种278个株的形态差异值和分子差异值的散点图分析，得出形态差异值≥2为异型株；由形态一致性比率和分子一致性比率的相关性系数为0.98，相关极显著，确定分子差异值≥2作为判定异型株的标准。

These findings provided morphological data for clarifying the immune mechanism of recombinant BCG-Sj26GST vaccine of schistosome.

这些结果为阐明血吸虫重组BCG-Sj26GST疫苗的免疫机制提供了形态学资料。

Presented polymorphism, from south-east, mid-part to north-west of Yunnan plateau, or with the latitude or altitude increasing, the general trend of the morphological variance was the tendency of miniaturization: the length of needles, size of the buds, frequency of the 3 needles per bundle, needle number per bundle, size of the female cone and its scute, the width of the wood growth ring and the needle area of transverse section decreasing.

论文作者王昌命导师姜汉侨教授学科专业生态学研究领域\研究方向植物生态学学位级别博士学位授予单位云南大学学位授予日期2002 论文页码总数106页关键词松树云南松馆藏号BSLW /2003 /S791 /5 本研究遵循生态学的原理和方法，对分布在滇东南、滇中以及滇西北地区的10个云南松种群就树皮、木材、针叶、球果等10多个形态性状进行了系统地观察统计分析。

Objective To investigate the cardiac morphological return after closure of secundum atrial septal defect with transcatheter technique, and also its follow-up results.

摘要］ 目的探讨采用介入治疗的方法进行房间隔缺损封堵术后心脏的形态学变化及其随访结果。

Chromosome pairing behavior in meiosis of the hybrid F1 was carried out. Results showed that in an average , 1.25 rod bivalents were observed in one PMC, meiotic configuration was 2n=14=11.49Ⅰ+1.25Ⅱ(Xta=1.25) and most of PMCs possessed 1～5 bivalens, indicating that the relatively high homeology was detected between the D genome of Ae.tauschii and the V genome of D.villosum. The morphological differences between F1 hybrids and their parents were significant. F1 plants were highly self-sterile, but partially self-fertile after treated by chromosome doubling technique.

对杂种F1花粉母细胞减数分裂中期Ⅰ染色体配对行为进行观察发现，"节节麦×簇毛麦"杂种F1平均每PMC有1.25个棒状二价体，染色体的平均构型为2n=14=11.49Ⅰ+1.25Ⅱ(Xta=1.25)，大部分被观察的细胞出现1～5个二价体，表明节节麦D染色体与簇毛麦V染色体间具有相对较高的部分同源配对， D和V染色体之间存在一定的部分同源性。F1植株高度自交不育，经染色体加倍处理后能够自交结实。
