Abstract Title:
The Effect of Oral Consumption of Propolis Alone and in Combination With Silver Nanoparticles on Wound Healing in Male Wistar Rats.
Abstract:
: Research to identify and develop compounds that facilitate wound healing is important, especially for hard-to-heal chronic wounds.PURPOSE: This study was conducted to investigate the effects of orally administered propolis (a resinous substance found in beehives), alone and in combination with silver nanoparticles (SNPs), on the wound healing process in male rats.METHODS: Forty (40) male Wistar rats were randomly divided into 4 groups of 10 each: 1 control group received no treatment, and 3 study groups received a daily dose of 1) propolis (100 mg/kg), 2) propolis + 30 ppm SNPs, or 3) propolis + 60 ppm SNPs. Healing rate was determined by wound surface area reduction on days 4, 6, 8, and 10 post-surgery. On day 12 after wound creation, histological changes of wound healing, including number of new vessels, inflammatory cells (neutrophils, eosinophils, and mast cells) and fibroblasts were counted based on morphology using a 400x objective lens, and collagen deposition density was determined using hematoxylin and eosin and trichrome staining, respectively. The histological scores were based on a 0 to 4 scale from lowest to highest amount of improving tissue status and were analyzed using one-way analysis of variance, Tukey test, Kruskal-Wallis test, t test, and Mann-Whitney U test to examine differences among the groups. Significance was set at P
