Figure 4.
Na+/K+-ATPase activity representing the pump function of cell lines from corneal cell monolayers on the insert well area of 4.67 cm2. Potential difference (A) and short circuit current (B) were measured before and after adding the Na+/K+-ATPase inhibitor ouabain. *P<0.01, compared with HCEC (normal). HCEC, human corneal endothelial cell.
