Abstract

The swelling pressure of 62 +/- 2 mmHg and the fixed charge concentration of 15.7 +/- 1.9 mmol/kg H2O were determined in bovine corneal stroma using a dialysis method. The hydration of the dialyzed stromal tissues was independent of ambient Na concentration. The same relationship was observed by incubation of whole corneas mounted in modified Ussing chambers.

摘要

采用透析法测定了牛角膜基质的肿胀压力为62±2 mmHg，固定电荷浓度为15.7±1.9 mmol/kg H₂O。透析后基质组织的水合作用与环境钠浓度无关。将完整角膜置于改良的Ussing室中孵育也观察到了相同的关系。
