摘要

目的:比较二水磷酸二钙(DCPD)颗粒对大鼠子宫角粘连模型的抗粘连作用。材料与方法:以新生成年Wistar白化大鼠60只为实验动物。采用改良大鼠子宫角粘连模型诱导腹腔内粘连。对肿瘤坏死因子(TNF)-α、白细胞介素(IL)-1、血管内皮生长因子(VEGF)和转化生长因子(TGF)-β1进行生化和免疫组化检查。结果:TNF-α在各组均呈下降趋势，G2、G3组下降幅度大于G1组。IL-1β在各组均呈下降趋势，其中G3组下降幅度最大。TGF-β1和VEGF在G2中的定位较G1少，G3和G4中TGF-β1和VEGF的免疫定位最少。这两种抗体在所有组中定位最少的都属于G3。从第7天到第21天，G1的TGF-β1免疫定位最高，G2的定位较低，G3的定位最低。结论:DCPD纳米颗粒作为抗黏附剂具有广阔的临床应用前景，值得进一步开展动物实验和人体试验。

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.
