Anti-adhesive effect of naturally obtained dicalcium phosphate dihydrate nanoparticles in the rat uterine wound model.

OBJECTIVE

In this study, we aimed to compare the anti-adhesive effects of contractubex and dicalcium phosphate dihydrate (DCPD) particles in rats treated with the uterine horn adhesion model.

MATERIALS AND

METHODS

Newly adult, 60 Wistar albino rats were used as experimental animals. The modified rat uterine horn adhesion model was used to induce intra-abdominal adhesion. Tumor necrosis factor (TNF)-α, interleukin (IL)-1, vascular endothelial growth factor (VEGF) and transforming growth factor (TGF)-β1 were studied for biochemical and immunohistochemical examination.

RESULTS

TNF-α decreased in each group, while it decreased more in G2 and G3 than in G1. IL-1β decreased in each group, while it decreased the most in G3. TGF-β1 and VEGF localization was less in the G2 compared to G1, the least TGF-β1 and VEGF immunolocalization was detected in the G3 and G4. For both antibodies, the least localization among all groups belonged to G3. From day 7 to day 21, the highest TGF-β1 immunolocalization was observed in G1, lesser localization in G2 and lowest in G3.

CONCLUSION

DCPD nanoparticles show promise as a clinical antiadhesive agent and should be further evaluated in experimental animal models and human trials.
