Designing a New Nano-Plant Composite of Cucurbita pepo for Wound Repair of Skin in Male Albino Mice: A New Nano Approach for Skin Repair

The Cucurbita pepo is one of plants that are functional in traditional therapy. This plant has antioxidant and skin damage repair properties. This study investigated the effect of Cucurbita pepo nano silver as a new nano-plant composition in wound repair skin in male mice. In this investigation، male albino mice were places in 8 groups، each containing 8 animals. Group I – VIII were treated with nano silver (500، 250، and 125 ppm concentrations and different concentrations of extracts [70%، 50%، and 25%]) and the control group received a mixture of 25% Cucurbita pepo extract (125 ppm) nano silver. The eighth group، as control، was treated with sterile deionizer water after the induction of wound skin. The average diameter of the wounds was measured 28 days after treatment in the control and treatment groups. These data were analyzed using the t-test and ANOVA statistical method. The results of this study showed that ethanol extraction (80%) has its highest repair effect 28 days post treatment. The average diameter of the wounds in the control group was 1. 16 ±. 0. 46 cm، which was decreased to 0 cm and 0. 12 ±. 0. 23 cm in the ethanol extract (70%) of the Cucurbita pepo and component groups، respectively (p value ≤ 0. 01). In this project، nano silver-Cucurbita pepo ethanol extraction for wound repair in albino male mice was more effective than single materials. These findings show that the repair synergic effects are between alcoholic extract and nano silver in this nano composite.
