Abstract
Oxygen permeability (Dk) of 15 rabbit and 19 human cornea stromal samples was measured by conventional polarographic means at 36 C. Hydration and thickness were also measured. Rabbit stromal permeability was found to be about 26 X 10(-11) ml O2 cm2/sec ml mmHg at normal in vivo hydration; in vivo human cornea stromal permeability is probably less than 29 X 10(-11) ml O2 cm2/sec ml mmHg.
摘要
采用传统极谱法在36℃下测量了15个兔角膜基质样本和19个人角膜基质样本的透氧性（Dk）。还测量了水合作用和厚度。发现兔基质在正常体内水合作用下的渗透率约为26×10⁻¹¹ ml O₂ cm²/sec ml mmHg；人角膜基质在体内的渗透率可能小于29×10⁻¹¹ ml O₂ cm²/sec ml mmHg。
