Background: Following the production of Syrian gel, the scientists from Atomic Energy Commission of Syria, in cooperation with researchers in Yazd Atomic Energy Commission Radiation Processing Center in Iran, have manufactured a hydrogel wound dressing. This study was conducted to evaluate and compare the efficacy of these two hydrogels.

Methods: In this study, 32 male Wistar rats underwent a full thickness circular skin wound on the dorsum under light anesthesia. Animals were divided into two groups. Wounds in the 1st group were dressed by the Syrian hydrogel and in the 2nd group by Iranian gel. Wound contraction rate was determined on days 1, 3, 7 and 12 for comparing the wound healing rate in two groups. Laboratory investigation of blood samples, skin tensile strength and histopathology of repaired skins were also evaluated.

Results: Wound contraction ratio on 7th and 12th days in Iranian gel was significantly greater than Syrian gel group. According to histopathological evaluations, wound repair in 63.6% of specimens in Iranian gel group was excellent and in 35.5% good while in Syrian gel group, 54.5% of repaired wounds were graded as excellent and 1 case showed to be in a weak repairing state. A significant difference was noticed in wound repair patterns between the two groups. The differences in skin tensile strength in two groups on days 15 and 30 were not significant.

Conclusion: According to our findings Iranian and Syrian hydrogels did not show any adverse effects on wound healing in rats and could be easily removed from the wound area without any trauma. However Iranian hydrogel dressings were more effective in wound repair regarding wound contraction rate and histopathological evaluation of the skin specimens in the region of healed wounds.
