Comparison of honey and dextrose solution on post-operative peritoneal adhesion in rat model

Peritoneal adhesion between abdominal organs is a complication of surgery. It causes major complications like pain, bowel obstruction, infertility and increases risk of death. Honey is known to have anti-inflammatory and antioxidant properties potentially relevant for adhesive protection.

Thirty rats were divided into five groups: negative control without any surgical procedure (normal group), control group treated with normal saline, experimental group I treated with 1ml of 10% honey, experimental group II treated with honey at half concentration of group I (honey0.5), and positive control group receiving 1ml of dextrose 5%. Inflammatory, growth and angiogenesis factors (TNF-α, Il-6, IL-1β, TGF-β1 and VEGF) of the adhesion tissue were assessed using ELISA. Antioxidant factors (NO, GSH and MDA) were also assessed using biochemical procedures.

The difference between peritoneal adhesion scores, TNF-α, IL-1β, IL-6, TGF-β1, VEGF, NO, GSH and MDA value of all groups was strongly significant (p<0.001). We showed that honey can decrease peritoneal adhesion (p<0.001), TNF-α (p<0.001), IL-1β (p<0.001), IL-6 (p<0.001), TGF-β1 (p<0.001), VEGF (p<0.001), NO (p<0.001), MDA (p<0.001) and increase GSH (p<0.001) compared with control group. Honey 0.5 also significantly decreased peritoneal adhesion (p<0.001), TNF-α (p<0.001), IL-1β (p<0.01), IL-6 (p<0.001), VEGF (p<0.001), NO (p<0.001), MDA (p<0.01) and increase GSH (p<0.001) compared with control group.

We find that honey can decrease inflammatory, growth and angiogenesis factors which can advance peritoneal adhesion and increase antioxidant factors. Honey could serve as a protective agent for peritoneal adhesion.
