摘要
通过不同压力下兔角膜真空冷冻干燥的实验研究 ,认为采用变幅值、变周期的循环压方法可以提高冻干兔角膜的活性。得出冻干循环压力法参数 :压力幅值 ,压力周期的优化是提高角膜活性的关键。
Rabbit cornea was successfully freeze dried by cyclic pressure freeze drying.We suggest that the period and pressure amplitude in the cyclic pressure drying should be carefully optimized because these two key factors significantly affect the surviving rate of the rabbit cornea.
