| Wound healing is an inflammatory process. Chrysin, a natural flavonoid found in
honey, has been recently investigated to have anti-inflammatory and antioxidant
effects. In this work, the effects of chrysin-loaded nanofiber on the expressions of
genes that are related to wound healing process such as P53, TIMPs, MMPs, iNOS,
and IL-6 in an animal model study were evaluated. The electrospinning method was
used for preparation the different concentrations of chrysin-loaded PCL-PEG nanofiber (5%, 10%, and 20% [w/w]) and characterized by FTIR and SEM. The wound
healing effects of chrysin-loaded PCL-PEG nanofiber were in vivo investigated in
rats, and the expressions of genes related to wound healing process were evaluated
by real-time PCR. The study results showed chrysin-loaded PLC-PEG compared to
chrysin ointment and control groups significantly increase IL-6, MMP-2, MMP-8,
MMP-9, TIMP-1, and TIMP-2 (p < .05). On the other hand, nanofibers containing
chrysin significantly decreased p53 and iNOS expression compared to chrysin ointment and control groups (p < .05). According to the results, chrysin-loaded PCLPEG-PCL nanofibers have positive effects on the expression of the genes that have
pivotal role in wound healing. |
