Introduction:
Impaired diabetic wound healing is an important issue in diabetic complications. The present study aims to evaluate the protective effect on glycemic control against impaired diabetic wound healing using a diabetic rat model. We investigated the wound healing process and effect on the impaired wound repair by glycemic control in the Spontaneously Diabetic Torii (SDT) fatty rat, which is a new animal model of obese type 2 diabetes and may be a good model for study impaired wound healing.
Material And Methods:
Male SDT fatty rats at 15 weeks of age were administered orally with sodium glucose co-transporter (SGLT) 2 inhibitor for 3 weeks. Wounds were induced at 2 weeks after SGLT 2 inhibitor treatment, and the wound areas were periodically examined in morphological and histological analyses.
Results:
The SDT fatty rats showed a delayed wound healing as compared with the normal rats, but a glycemic control improved the impaired wound healing. In histological analysis in the skin of SDT fatty rats showed severe infiltration of inflammatory cell, hemorrhage and many bacterial masses in the remaining and slight fibrosis of crust on skin tissue. Thought that this results skin performance to be a delay of crust formation and regeneration of epithelium; however, these findings were ameliorated in the SGLT 2 inhibitor treated group.
Conclusion:
Glycemic control is effective for treatment in diabetic wounds and the SDT fatty rat may be useful to investigate pathophysiological changes in impaired diabetic wound healing.
Insights
Glycemic control significantly improves impaired wound healing in diabetic rats. This study highlights the effectiveness of managing blood sugar for diabetic wound treatment using a novel obese type 2 diabetes model.
Area of Science:
- Endocrinology
- Wound Healing Research
- Diabetology
Background:
- Impaired diabetic wound healing is a significant complication of diabetes.
- The Spontaneously Diabetic Torii (SDT) fatty rat, an obese type 2 diabetes model, was used to study wound repair.
- Understanding delayed wound healing in diabetes is crucial for developing effective treatments.
Purpose of the Study:
- To evaluate the protective effect of glycemic control on impaired diabetic wound healing.
- To investigate the efficacy of a sodium glucose co-transporter (SGLT) 2 inhibitor in improving wound repair in a diabetic rat model.
- To assess the utility of the SDT fatty rat as a model for studying diabetic wound pathophysiology.
Main Methods:
- Male SDT fatty rats (15 weeks old) received oral SGLT 2 inhibitor treatment for 3 weeks.
- Wounds were induced in the rats 2 weeks after the SGLT 2 inhibitor treatment began.
- Morphological and histological analyses were performed to examine wound healing progression.
Main Results:
- SDT fatty rats exhibited delayed wound healing compared to normal rats.
- Glycemic control, achieved with SGLT 2 inhibitor treatment, improved impaired wound healing.
- Histological examination revealed severe inflammation, bacterial masses, and delayed tissue regeneration in untreated SDT rats, which were ameliorated by the SGLT 2 inhibitor.
Conclusions:
- Glycemic control is an effective therapeutic strategy for diabetic wounds.
- The SDT fatty rat model is valuable for investigating the pathophysiology of impaired diabetic wound healing.
- SGLT 2 inhibitor treatment shows promise in enhancing diabetic wound repair.
