    • An exogenous stimulus is applied to tissues or cells which are at risk in a subsequent surgical procedure or other intervention which induces a response by the cells that minimizes reaction to the subsequent procedure. Stimuli can be chemical, physiological or physical. Examples include those stimuli known to induce expression of stress response proteins or heat shock proteins, especially heat shock protein 70 (hsp 70) and hsp 90, for example, exposure to heat or dilute hydrogen peroxide, or direct administration of exogenous heat shock proteins, or those stimuli which act to inhibit or reduce heat shock protein expression, for example, treatment with flavonoids. An amount effective to modulate levels of stress response proteins or reduce the endogenous response is administered, based on in vitro assays which are used to determine levels of heat shock proteins or which are experimentally determined to reduce cell proliferation, thrombus formation, and matrix deposition following subsequent exposure to a procedure. Procedures can be surgery, angioplasty, or abrasion. The method and compositions are also useful in mediating some disease processes, where the process involves undesirable migration.
    • 外源刺激被应用于随后的外科手术或其它干预中处于风险中的组织或细胞,其诱导细胞的反应使得对后续过程的反应最小化。 刺激可以是化学,生理或物理。 实例包括已知诱导应激反应蛋白或热休克蛋白表达的刺激物,特别是热休克蛋白70(hsp70)和hsp90,例如暴露于热或稀释过氧化氢,或直接施用外源热休克蛋白, 或用于抑制或减少热休克蛋白表达的那些刺激物,例如用类黄酮治疗。 基于用于测定热休克蛋白水平或经实验确定以减少细胞增殖,血栓形成和基质沉积的体外测定,施用有效调节应激反应蛋白水平或降低内源性应答的量 随后接触一个程序。 手术可以是手术,血管成形术或磨损。 该方法和组合物也可用于介导某些疾病过程,其中该过程涉及不期望的迁移。
