PV-10 is an injectable formulation of rose bengal disodium (RB) (4,5,6,7-tetrachloro-2',4',5',7'-tetraiodofluorescein disodium salt), which is a small molecule halogenated xanthene and PV-10's active pharmaceutical ingredient.
Panotico staining was performed according to the following procedures: slides were immersed in (1) 0.1% triarylmethane solution, (2) 0.1% xanthene solution, and (3) 0.1% thiazine solution; the slides were kept in each solution for 5 seconds.
Riboflavin (RF), camphorquinone (CQ) and xanthene dyes are commonly used as sensitizers in preparing hydrogels, because they possess biocompatibility and low cytotoxicity [7-9].
Reactive oxygen species, such as hydrogen peroxide and superoxide, are produced by xanthene oxidase.13 Drugs like allopurinol and febuxostat inhibit xanthene oxidase to reduce oxidative stress which results in LVH reduction.14 In addition, Dundee et.al has already reported the role of allopurinol in the regression of LVH in CKD and IHD patients.11,15 International data on the role of allopurinol in reducing LV mass both in CKD and in patients with normal renal functions is available but local literature is lacking.11,15 The current study was planned to fill that knowledge gap.
