CTAB was used to pyrolyse plant cell and reacted with the released cell nucleic acid to form nucleic acid-CTAB complex, the cell extract was then deproteined with chloroform-isoamylol, at last RNA was selectively precipitated by LiCl.

采用CTAB裂解植物材料，与细胞中的核酸形成核酸-CTAB复合体，然后用氯仿一异戊醇去除细胞裂解液中的蛋白，最后采用LiCl选择性沉淀其中的RNA。

CTAB was used to pyrolyse plant cell and reacted with the released cell nucleic acid to form nucleic acid-CTAB complex,the cell extract was then deproteined with chloroform-isoamylol,at last RNA was selectively precipitated by LiCl.

To understand the infectivity by porcine endogenous retrovirus with porcine skin fibroblast cell in vitro and in vivo, porcine skin fibroblast cell established by our laboratory were co-cultured with neo/HEK293 cell for the infection of RERV in vitro, and were subcutaneously transplantated to SCID (severe combined immuno-deficiency) mice for the infection of PERV in vivo, laying the foundation for valuation of biologic safety of xenotrans-plantation. The event of neo/HEK293 cells infected by PERV occurred during co-culture of porcine skin fibroblast cells with neo/HEK293 cells, expanding the rang of the infection of porcine endogenous retrovirus. Afterpig cells transplantated subcutaneously in SCID mice, the microchimerism (78.57%) of pig cells occurred widel, and there was phenomena of integration of PERV provirus (85.71%) in several organs or tissues remote from the injected sites, indicating infection of PERV in SCID mice in vivo. yet, there is no evidence of active viral replication in analysis of PERV env RNA of these tissues or organs.

为了解猪皮肤成纤维细胞PERV在体外和体内的感染性，通过建立猪皮肤成纤维细胞系，将所建细胞系与人胚胎肾293细胞体外共培养，并移植于严重联合免疫缺陷鼠皮下进行猪皮肤成纤维细胞PERV的体外和体内感染性实验，结果表明，猪皮肤成纤维细胞与人胚胎肾细胞共培养过程中，猪内源性逆转录病霉感染人胚胎肾细胞，进一步证实和拓宽了猪细胞PERV感染人细胞的范畴；猪皮肤成纤维细胞移植SCID鼠皮下后，导致SCID鼠发生猪细胞微嵌合(78.57%)和PERV在体内感染(85.71%)并且波及远离移植部位的多种组织或器官，但是并未检测出SCID鼠组织中表达PERV env RNA。

A number of lines evidence indicate that calcium treatments maintain the structure and function of the cell walls, increase the fruit firmness, decrease the activity of the cell wall degration enzymes and ethylene production, maintain the integrity and stability of the membrane, activate some oxidases, induce phytolexin and regulate cell function as a signal mobecular.

钙的防腐机制在于对果蔬采后腐烂的控制，保持细胞壁的结构与功能，增强果实硬度，降低细胞壁降解酶的活性，抑制呼吸，降低乙烯生成量，保持细胞膜的完整性，激活体内的某些氧化酶，诱导合成植保素，作为信号分子，调节细胞功能。
