Omegaven Improves Skin Morphometric Indices in Diabetic Rat Model Wound Healing

Abstract

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.
