Materials and are consistent with these obtained by Shi and colleagues [45] on a human liver cell line, in which OLE exerted a protective action from H2 O2 -induced oxidative 3.1. Materials damage in concentrations ranging from 0.004 to 0.0160 mg/mL. The materials made use of in this study were oleuropein (OLE; Sigma-Aldrich, St. Louis, Oxidative stress-induced damages around the corneal surface have been investigated, and MO, USA); hydroxypropyl–cyclodextrin reduction in antioxidant enzymes in individuals various clinical research [46,47] highlighted a parenteral grade (HP–CD; Kleptose, Roquette Freres, Lestrem, France);was associated to inflammation on the cular surface along with the with DES, the extent of which phosphatidylcholine (Pho; Lipoid S one hundred; Lipoid, GmbH, Ludwigshafen, Germany); cholesterolagain, it is shown that the Louis, MO, USA);point of severity of dry eye symptoms.
