The results showed:(1) The histological changes of KC were in fact a wound-repair process;(2) The increased melanin in KC coordinated with "multi-overlapping screen" effect, a result of multiple layers of "supranuclear cap", was the direct cause of hyperpigmentation of the graft and (3) The hydrolytic disturbance of melanin in KC and the longer life span of the KC were probably the important reasons for the increase of melanin in the epidermis.

结果表明，角朊细胞的组织学改变实际上是一个损伤后修复的过程；角朊细胞内黑色素含量增加及出现的多层次的&核上帽&状分布而形成的&多重帘幕&效应，是皮片过度色素化的直接原因；黑色素在角朊细胞内的降解障碍及角朊细胞更新周期延长可能是表皮内黑色素含量增多的重要原因。

Rostral midbrain atrophy in progressive supranuclear palsy is detected by mid-sagittal plain magnetic resonance imaging. The shape of the atrophy looks like the bill of a hummingbird.

In the study, a set of near isogenic lines of CMS-S, S-Mo17Rf3Rf3 and S-Mo17rf3rf3, were adopted, and TdT-mediated dUTP nick-end labeling, in situ immunolocalization of cytochrome c and DNA ladder assay were employed to study the programmed cell death process on cytology and DNA level. The microscope observation evidenced that tapetal cells of fertile anthers kept intact until microspores, and then were disintegrated on later developmental stage.

S型细胞质雄性不育系的一对近等基因系S-Mo17Rf3Rf3 和S-Mo17rf3rf3为材料，采用TdT介导的dUTP DNA末端标记、细胞色素C免疫原位杂交和DNA寡聚核小体片段电泳等方法，分别在细胞学水平和DNA水平上研究了玉米CMS-S小孢子败育的细胞程序性死亡过程。

This paper is the fourth section of the serial articles, it's primary contents included: based on the basic theory of the continuous medium mechanics, we have given rotational dynamical equations of the solid inner core of the Earth, taken into account influence of the self\|gravitational potential, of the fluid pressure acting on the instantaneous surface of the SIC, and of the degree 2 tesseral component of the tidal generating potential on the rotation of SIC, and has presented their practical expression, in order of magnitude of O.

中国科学院国家天文台/云南天文台，昆明 650011；2。徐州师范大学物理学系，徐州 221116；3。中国科学院测量与地球物理研究所，武汉 430077摘要：本文是序列文章的第四篇，其内容包括：基于连续介质力学的基本理论，给出了固体外核自转的动力学方程，考虑了地球的自引力、液核对内核边界的压力和二阶外部引潮力位对SIC自转的影响，并在O的量级上给出了其实用的表达式。

We have studiedthe coordination water-substituted reactions and the phase-transferchemistry of dozens of trinuclear or tetranuclear sandwich-typePOMs and found that organic molecules or polymers can becoordinated to these polyanions after dehydration, thus more thanone hundred coordinated products are obtained, indicating that thesepolyanions are excellent ligands in organic solvents.

我们首次对夹心三、四核等几十种化合物中配位水进行了配位水取代反应及相转移化学研究，脱水后可配位有机分子或有机高分子，得到上百种配位产物，因此在有机溶剂中它们是优秀的配体。

In this research, about forty percent cases suffered from unconsciousness of different degree. Reticular structure's distroy is the main cause for it. Reticular structure can transfer many kinds of impulsion to reticular neucli in thalamencephalon and active the relative domain of brain cortex.

脑干网状结构接受躯体感觉、内脏感觉、听觉和视觉等很多传导来的传入冲动，并将这些冲动传导给丘脑网状核，然后激活大脑皮层上广泛散布的有关区域，使皮层神经元保持兴奋状态以及维持意识的觉醒状态。

The effects of acetylcholine and atropine on the electric activities of neurons of nucleus parafascicularis thalami were observed in anesthetized rats with multimicropiptte technique and iontophoresis.

在30只大鼠上，用多管微电极细胞外记录和离子微电泳方法，观察了乙酰胆碱和阿托品对丘脑束旁核神经元电活动的影响。

Results MRI showed symmetric abnormal signals in basal ganglia in 27 patients, in thalami and dentate nucleus in 21 patients, and in corona radiata-centrum ovale in 9 patients. All the lesions were hyperintensity on T1WI. Local hypointensity in basal ganglia was found in 4 patients, while hyperintensity or slight hyperintensity on both T2WI and T2-FLAIR were found in 26 patients, and slight hyperintensity with hypointensity on both T2WI and T2-FLAIR in 1 patient.

结果 27例颅脑MRI表现为双侧基底节区片状对称性异常信号，21例双侧丘脑、齿状核片状异常信号，9例双侧放射冠－半卵圆中心见片状对称性异常信号；27例T1WI上见高信号区，其中4例基底节区病灶内见小片状低信号；26例T2WI及T2-FLAIR见高或稍高信号，1例见稍高、低混杂信号。

During the past 3 years, 2 independent experiments of sperm-mediated gene transfer in domestic silkworms were carried out respectively in 2000 and 2002 with the method direct injection of copulation thecae.

在同源重组绿色荧光蛋白表达载体pG350的基础上，以pMD18-T为质粒载体，用egfp基因替换gfp基因，构建了家蚕核型多角体病毒早期即刻蛋白基因启动子BmNPV-IE控制下的增强型绿色荧光蛋白表达载体pMD-Fib-IE-EGFP。
