The global prevalence of diabetes is estimated to be 200 million people, and it is likely to increase to 333 million people by 2025. Different cells, are known to participate in three main phases of wound healing. Omega-3 fatty acids influence cytokines and growth factors which affects the presence of inflammatory cells in wound area as well, but how this event specifically influences the role of fibroblasts, macrophages and angiogenesis in wound healing is not obviously understood. In this experimental study seventy male Wistar rats after induction of diabetes type-one by streptozotocin (STZ) (55 mg/kg) were divided into two groups, Experimental group receiving omegaven intraperitoneally and control group which underwent the injection of mineral oil. Streptozotocin was used for the induction of diabetes type 1. Diabetic male wistar rats were scarified at 1, 3, 5, 7 and 15 days after the excision was made. To estimate orphometric indices, histological sections were provided by stereological methods. It was found that wound area significantly decreased on day 7 in experimental group by omega-3 fatty acids. The number of fibroblasts increased significantly on days 5 and 7 in the experimental group. The number of neovascular significantly decreased on day 7 in the experimental group. This study implied that it seems omegaven is able to improve morphometric indices during wound healing and make healing faster.
据估计,全球糖尿病患者人数达2亿,到2025年可能增至3.33亿。已知不同细胞参与伤口愈合的三个主要阶段。ω-3脂肪酸会影响细胞因子和生长因子,这也会影响伤口区域炎症细胞的存在,但这一过程具体如何影响成纤维细胞、巨噬细胞的作用以及伤口愈合中的血管生成尚不清楚。在这项实验研究中,70只雄性Wistar大鼠经链脲佐菌素(STZ)(55毫克/千克)诱导产生1型糖尿病后,被分为两组,实验组腹腔注射Omegaven,对照组注射矿物油。链脲佐菌素用于诱导1型糖尿病。在切除术后第1、3、5、7和15天处死糖尿病雄性Wistar大鼠。为评估形态学指标,采用体视学方法制作组织切片。结果发现,实验组中ω-3脂肪酸使伤口面积在第7天显著减小。实验组中成纤维细胞数量在第5天和第7天显著增加。实验组中新生血管数量在第7天显著减少。该研究表明,Omegaven似乎能够改善伤口愈合过程中的形态学指标并加快愈合速度。
