Abstract (original English)

Experimental studies have shown that the effects of stromal vascular fractions and platelet-rich plasma on deep dermal burn healing were encouraging. By measuring the blood level of platelet-derived growth factor (PDGF)-BB, we evaluated their effect on full-thickness burns in this study. Forty-eight Wistar rats were separated into four main groups: group A rats were administered combined SVF and PRP injections, group B rats were topically administered Vaseline, group C rats were administered placebo injections, and group D rats were without burns. Depending on the day of euthanasia, these groups were further divided into subgroups (8th hour, 4th day, 7th day, 14th day, and 21st day). Using enzyme-linked immunosorbent assay, the serum level of platelet-derived growth factor-BB was determined. Friedman's test or the analysis of variance test was applied, and p-values under 0.05 were regarded as significant. The PRP+SVFs group had the highest mean PDGF-BB levels overall on days 4, 7, 14 and 21 (1.81±1.04 pg/ml, 1.24±0.41 pg/ml, 2.21±0.60 pg/ml, and 3.10±1.02 pg/ml, respectively). The repeated ANOVA test (Mauchly's test of sphericity) resulted in a p-value of 0.556 (>0.05), indicating that the variance of the PDGF-BB data was the same. Additionally, a p-value of 0.001 demonstrated a significant difference in the levels of PDGF-BB between the groups. Overall, the mean PDGF-BB level
