The significant changes were obseved in the morphology,size,number and the degree of development of nuclei,nucleole,mitochondrial and chloroplast of apicalmeristem cell.

在这期间茎端细胞内核仁、线粒体、叶绿体等的形态、大小、数量、发育程度等发生明显变化。

Objective: To investigate the effect of tanshinone ⅡA on HL-60 and K562 cells apoptosis,and to assay the inhibition of the telome rase activities in the leukemia cell apoptosis induced by Tanshinone.

中文摘要：目的观察丹参酮ⅡA对HL60，K562细胞端粒酶活性的抑制作用和对凋亡相关基因的影响，探讨丹参酮ⅡA对造血细胞的作用机理。

Two polar nuclei move to the micropylar end before sperm is released in a gap between the egg cell and central cell and subsequently taking off cytoplasm one after another. The sperm nucleus moving to the egg nucleus runs faster than the one to the polar nuclei. It fuses with the polar nuclei that are moving towards the antipodal cells at the chalazal end.

精子释放前，两极核移向卵细胞的合点端；两精子释放于卵细胞与中央细胞的间隙后，先后脱去细胞质，然后分别移向卵核和极核，移向卵核的精核快于移向极核的精核；精核与两极核在向反足细胞团方向移动的过程中完成雌雄核融合。

The sperm nucleus moving to the egg nucleus runs faster than the one to the polar nuclei. It fuses with the polar nuclei that are moving towards the antipodal cells at the chalazal end, Images showed the fusion process of male and female nuclei and polyspermous fertilization.

Following studies had been performed:(1)repetitive WLT and real-time ultrasonography had been performed to 18 HS and 40 FD toassess the reproducibility and influencing factors.(2) correlations of WLT with symptomscore and electrogastrography had been analysed.(3) differences ofWLT between HS and FD had been compared.(4) methophenolane andimmunohistochemistry stain of gastric fundus mucosa biopsy from 40 FD patients hadbeen performed to analyse the correlations of symptom score and WLT with count andactivity of mast cells, 5-HT level, and H.Pylori infectious status.(5) the effect of oralsumatriptan to proximal stomach function in 10 HS and 10 FD had been assessed, so as toestablish the possible regulating mechanism of fundic relaxation, explore the therapeuticpotential and feasibility of sumatriptan on FD.Results:I. Evaluation of WLT and its application in FD management.

我们主要进行以下几个方面的研究：(1)对18名健康人及40名FD患者重复进行水负荷试验并结合B超声对近端胃的实时监测，评价水负荷试验结果的可靠性并分析其影响因素；(2)观察水负荷试验结果与症状积分及体表胃电结果的相关性；(3)比较FD患者和健康成人水负荷试验结果的差别；(4)对40名FD患者胃底粘膜活检组织进行免疫组化染色和甲苯胺蓝染色，观察FD患者的症状及水负荷试验结果与胃底粘膜肥大细胞、5-HT表达情况及H.pylori感染情况的相关性：(5)观察口服舒马曲坦对10名健康人及10名FD患者近端胃功能的影响，并由此推测胃底舒张运动调节的生理机制，探讨口服舒马曲坦治疗FD的可行性。

Objective: To investigate the telomerase activity of peripheral blood mononuclear cells from patients with essentail hypertension.

目的：探讨高血压病患者外周血单个核细胞的端粒酶活性。

Then glutamate, GABA and GABA_BR1 in cells on bone trabecula surface of distal fermur of rats in every group were checked with immunohistochemistry method.
