These observations show that reprogramming is easier in interspecific embryos reconstructed with ES cells than that reconstructed with somatic cells, and that ES cells have the higher ability to direct the reconstructed embryo development normally than fibroblast cells. Oocytes were reconstructed with outbreeding Kunming albino mouse ES cells and enucleated rabbit oocytes, and the effects of the passages of ES cells and 6-DMAP on the development of interspecific reconstructed oocytes were analyzed. The interspecific reconstructed ES-rabbit oocytes were activated either by combined two set electric pulses and 6-DMAP or by two set electr

以上结果显示，6－DMAP能增加胚胎干细胞异种重构卵的卵裂率，对重构卵囊胚的发育率影响不大；高培养代数和低培养代数的胚胎干细胞用于异种核移植不影响异种重构卵的卵裂率和囊胚发育率；用胚胎干细胞作为供核细胞；比体细胞作为供核细胞所构建的异种重构胚更容易进行重编程，并且胚胎于细胞指导异种克隆胚胎正常发育的能力强于体细胞。

RESULTS: The positive staining cells mostly included ependymal cells of myelocoele, glial cells, motor neurons, and epithelial cells of spinal pia mater. The staining was mainly located on the cell membrane. Most importantly, it displayed certain directivity in the glial cells, mainly at the membrane side contacting with capillary endothelial cells.

Results Trunk neural crest stem cells were successfully isolated and cultured. The immuocytochemcal result showed that the cells were nestin-and P75-positive. Trunk neural crest stem cells grew through adhering to chitosan fiber after inoculation. Under an electon microscope, the spindle-shaped trunk neural crest stem cells were proliferated and migrated along the fiber. The cells arranged side by side or linked by heads and tails in processes. The ends of S-100 positive cells were flat and expanded, adhering to the fiber as claw-shaped pseudopodium.

结果 采用神经管植块法培养的神经嵴干细胞，免疫细胞化学染色呈现nestin及P75双阳性，将其接种在壳聚糖纤维支架材料上，可见神经嵴干细胞贴附于壳聚糖纤维上生长；S-100免疫细胞化学染色显示，S-100阳性细胞突起的末端呈扁平状膨大；扫描电镜显示，壳聚糖纤维上的躯干神经嵴干细胞为梭形，呈现"端对端"、"肩并肩"排列，伸出爪形伪足贴附于壳聚糖纤维上。

The results showed that (1) the positive staining of ChAT was obviously observed in the cells of the three kinds of human pituitary adenoma, however, it was lower than that in normal human pituitary gland;(2) ACh had a similar effect on the proliferation of the three kinds of human pituitary adenoma cells. ACh at 0.1～10 μmol/L decreased the ［3H］TdR incorporation and the MTT A value in a dose-dependent manner. At the same time, ACh decreased the ratio of S or G2 phase pituitary adenoma cells significantly, but increased the ratio of G1 phase pituitary tumour cells markedly;(3) the effect of acetylcholine on the proliferation of human pituitary adenoma cells was inhibited by atropine, but not by tubocurarine;(4) ACh had no effect on the apoptosis of human pituitary adenoma cells cultured in vitro.

结果发现：(1)三种垂体腺瘤细胞中均有胆碱酯酶的表达，但明显少于正常垂体；(2)ACh对三种类型的人垂体腺瘤细胞增殖代谢的影响相类似，不同浓度的ACh能明显抑制体外培养的三种人垂体腺瘤细胞的增殖，呈明显的剂量效应关系，同时ACh能减少垂体腺瘤细胞进入S、G2期的细胞比例，而使处于G1期的细胞比例增加；(3)ACh的这种作用可被阿托品阻断，但不受筒箭毒的影响；(4)ACh对体外培养的三种人垂体腺瘤细胞凋亡无明显影响。

Tumor cells grew actively in the tumor tissues of the control group. Prodrug therapy group: small amount of tumor cells were denatured vacuously,others were infiltrated by lympholeukocyte,and the growth of tumor cells were surspressed.Prodrug themochemotherapy group: what we can see that tumor cells were denatured vacuously, mesoplasts crinkled, cellular boundary disappered, only a small number of tumor cells remained, fibroblast were seen scatteredly, tumor cells were invaded by a lot of lympholeukocyte and eosinophilic granulocyte. Normal liver tissues, stomach tissues, lung tissues, pancreas tissues, small intestine tissues, large intestine tissues showed normal shape.

对照组肿瘤组织见肿瘤细胞生长活跃；前药治疗组肿瘤组织见有少量细胞空泡变性，少量淋巴细胞浸润，肿瘤细胞生长受到抑制；前药热疗组肿瘤组织可见肿瘤细胞空泡变性，细胞核皱缩，边集甚至消失，仅残留少量肿瘤细胞，并可见散在的成纤维细胞，大量淋巴细胞和嗜酸性粒细胞浸润；3组裸鼠正常肝组织、胃、肺、胰腺、小肠、大肠组织均呈正常形态学，无病理性损伤改变。

The granulation index, MDA and activity of SOD in granulated cells were larger than in non-granulated cells; similar to POD's, SOD activity also reduced, but SOD activity in granulated cells of apomictic fruit reached bottom earlier than in non-granulated cells; GSH and ASA of non-granulated cells were higher than those of granulated cells; granulation of Citrus guanxi-miyou might related to disorder of active oxygen metabolism

SOD活性的变化趋势与POD活性相似，但自交果粒化汁胞SOD活性出现最低点时间早于未粒化汁胞；未粒化汁胞GSH 、AsA含量大于粒化汁胞。琯溪蜜柚果实汁胞粒化可能和汁胞的活性氧代谢失调有关。

objective effects of plant tannins,chebulinic acid and tellimagrandin i on chemically induced hemoglobin synthesis in k562 cells were investigated.methods the hemoglobin synthesis situation was assayed with benzidine staining.erythroid antigens glycophorin a expression on the surface of k562 cells was labeled by direct immunofluorescence using fluorescein isothiocyanate-conjugated anti-gpa antibodies.then flow cytometric analysis was performed to detect gpa expression levels on surface of the cells.results both chebulinic acid and tellimagrandin i could inhibit the hemoglobin synthesis of butyric acid and hemin-treated k562 cells in a concentration-dependant manner.however,the ba-induced k562 cells were more sensitive to two tannins than heroin-induced cells.conclusion chebulinic acid and tellimagrandin i have inhibitory effect on the erythroid differentiation.
