Indole-3-carbinol loaded-nanocapsules modulated inflammatory and oxidative damages and increase skin wound healing in rats. | LitMetric

AI Article Synopsis

  • The study investigated the effects of hydrogels (HG) infused with nanoencapsulated indol-3-carbinol (I3C) on skin wounds in rats, applying them twice daily for five days.
  • On day three, the treated groups experienced less wound enlargement compared to a control group, and by day six, certain hydrogel formulations showed reduced wound regression.
  • Specifically, the nanoencapsulated I3C in the hydrogel demonstrated significant anti-inflammatory and antioxidant benefits, indicating its superiority over the free form of I3C in promoting wound healing.

Article Abstract

This study evaluated the effects of topically applied hydrogels (HG) containing nanoencapsulated indol-3-carbinol (I3C) and its free form in a rat model of skin wounds. Formulations were topically applied twice a day for five days to the wounds. On days 1, 3, and 6, the wound area was measured to verify the % of regression. On the sixth day, the animals were euthanized for the analysis of the inflammatory and oxidative profile in wounds. The nanocapsules (NC) exhibited physicochemical characteristics compatible with this kind of suspension. After five hours of exposure to ultraviolet C, more than 78% of I3C content in the suspensions was still observed. The NC-I3C did not modify the physicochemical characteristics of HG when compared to the HG base. In the study, an increase in the size of the wound was observed on the 3rd experimental day, which was lower in the treated groups (mainly in HG-NC-I3C) compared to the control. On the 6th day, HG-I3C, HG-NC-B, and HG-NC-I3C showed lower regression of the wound compared to the control. Additionally, HG-NC-I3C exhibited an anti-inflammatory effect (as observed by decreased levels of interleukin-1B and myeloperoxidase), reduced oxidative damage (by decreased reactive species, lipid peroxidation, and protein carbonylation levels), and increased antioxidant defense (by improved catalase activity and vitamin C levels) compared to the control. The current study showed more satisfactory results in the HG-NC-I3C group than in the free form of I3C in decreasing acute inflammation and oxidative damage in wounds.
