The nanoplex were smaller than the unmodified nHAP; thelipiodol/nanoplex emulsion, with the mean diameter at 75±11.8nm can disperse moreuniformly and be more soluble and stable, contrary to the unmodified nHAP and nanoplex Conclusion: Nanoplex/pDNA mass ratios greater than 15 had exhibited completepDNA absorption onto positive charged polyplex and pDNA protection from thedestruction of nucleinase in rabbit serum. Unmodified nHAP may can\'t induce effectivegene delivery.PartⅡThe construction of the recombint eukaryotic expressive vector ofwild-type human p53 and RbObjective: To construct the recombint eukaryotic expressive vector of wild-type humanp53 and Rb by utilizing the theory of molecular medicine.

结果nHAP颗粒本身大小小于100nm，但由于颗粒表面本身带负电，不能包括有效地结合及保护DNA；经Ca~(2+)修饰后，颗粒可带正电，可一定程度地结合和保护DNA，但聚合物本身的中性电与带负电的细胞膜结合，而且本身的颗粒则变地容易聚集而成为很大的颗粒，也不利于细胞的吞噬；经PLL修饰后，颗粒溶解性提高，直径变小，表面带正电，电泳结果显示PLL-nHAP颗粒可包括有效地结合和保护DNA免受兔血清的破坏，而且复合物表面的正电也包括有利于与细胞膜的结合与吞噬。

Coli. Transmission electron microscopy was used to evaluate the cell morphology of both the normal and the treated E. coli. The observation with TEM suggested that silver nanoparticles lead to the formation of "pits" in cell wall of the bacteria, and silver nanoparticles could enter into periplasm through the pits and destroyed the cell membrane.

采用透射电镜观察了经纳米银粒子处理过的大肠杆菌细胞形态变化过程，结果显示纳米银粒子先在细胞壁上产生小的孔洞，通过这些孔洞进入周质空间，导致细胞膜成分渗漏和破坏细胞膜，进而进入细胞内部。

The result showed that PSexternalization. This observation suggested that apoptotic neurons losed membranephospholipid asymmetry and exposed PS on the outer leaflet of the plasmamembrane. Macrophages then phagocytose apoptotic neurons after specific recognition of theexposed PS.

流式细胞术检测磷脂酰丝氨酸，结果表明凋亡的神经细胞PS外翻，证明AVM可使凋亡的神经细胞膜丧失不对称性，细胞膜中的PS由脂膜内侧翻向外侧，可被吞噬细胞识别后导致凋亡细胞的清除。

Objective:To study the effect of G6PD deficiency on membrane phospholipid structures. Methods: Treatment of intact erythrocyte with phospho- lipase A2 was used for the membrane phospholipid asymmetry.

The results of flow cytometry in normal, B27 single transgenic mice and B27/hβ〓m double transgenic mice were 0.63％, 7. 87％ and 35. 87％ respectively. B27 antigen was also expressed in the cell surface and cytoplasm of colon, skin, testis and eyes of the double transgenic mice by the detection of immunohistochemistry, which was evident on the cell surface. 8 double transgenic mice bearing high copy (7 males, 1 female) developed spontaneous alopecia, psoriasiform dermatosis, joint swelling and nail changes in the rear paw.

免疫组化检测可见转基因小鼠的结肠、皮肤、睾丸和眼睛组织的细胞膜和细胞浆均有B27抗原的存在，尤以细胞膜明显。21只B27/h〓转基因阳性鼠中有8只出现脱毛和皮肤的银屑病样改变，同时伴有后肢的关节肿胀和趾甲变化。8只小鼠均为高拷贝，其中雄性7只，雌性1只。
