Autologus serum and sodium hyaluronate role in alkali corneal burn healing

الملخص EN

Background/aim Corneal burn wound healing includes a sequence of difficult processes that are focused on improving the outcomes, in particular, the healing time and the feature of the scar.

Bodily fluids such as natural tears and autologus serum were used in the treatment of corneal burn.

The aim of the study was to investigate the cure of corneal burn alkali injury by autologous serum (AS) and/or sodium hyaluronate.

Materials and methods A total of 50 Wister rats (200–250 g) were distributed into five groups: group I acted as the control, group II had alkali burn (AB) with sodium hydroxide, group III had AB treated with AS, group IV was AB treated with sodium hyaluronate, and group V had AB with sodium hydroxide treated with autologus serum and sodium hyaluronate.

Comet assay analysis was applied for cornea to determine DNA damage.

Malondialdehyde, superoxide dismutase, glutathione peroxidase, and catalase were measured to estimate the balance between oxidants and antioxidants in the cornea.

Results The data indicated a significant increase (P<0.05) in all comet assay parameters and malondialdehyde level in addition to a significant decrease (P<0.05) in superoxide dismutase, glutathione peroxidase, and catalase activity owing to AB.

Enhancements of measured parameters were observed in all other treated groups.

Conclusion AS accelerates the AB healing process, but the process was faster when diluted by sodium hyaluronate.
