The extraction and stability of the pigments in Tussilago farfara L. were studied. The experimental results showed that the pigments could be solved in acetone. The stability of the pigments is good when pH is within 3~9; the oxidizing agents, reducing agents and common food additives have little influence on its stability; it is react too much with Fe(superscript 3+) ion, and Na(superscript +) ion showed a certain increment effect on the color; the heat performance of the pigments is good when under 60℃.

A potential approach to this problem is to make use of a natural defense mechanism called " the stress response," which is characterized by a transient down - regulated synthesis of nonvital cellular proteins and increased production of endogenous protective factors known as heat shock proteins that act to allow proper refolding of proteins denatured by the incipient injury.

应激反应的特征是一过性下调细胞非必需蛋白的合成及增加被称为热休克蛋白的内源性保护因子的合成。热休克蛋白作用是促使损伤导致变性的蛋白适当地再折叠。HSP家族中HSP70被认为在细胞保护中发挥重要作用。

Results The bletilla colloid was a homogenous viscous colloid whose relative viscosity was 2324.6 mm2/s. It was easily injected through 4-F catheter and hyperattenuating under fluoroscopy, meanwhile, with good histocompatibility and hemo-compatibility, without pyrogenetic response and toxicity. In vitro, the mixture of bletilla colloid and MMC did not produce separation and suspention phenomena but released 50%of MMC at 1.8h and 100%at 3.4h. The bletilla colloid mainly embolized peripheral arteries, maintaining occlusion for 5 weeks and without formation of collateral circulation. The injuries of normal hepatic tissues were slight, without hepatic cytonecrosis.
