Abstract
Introduction:
Cardiovascular disorders are one of the prominent causes of risks of mortality which accounts for high rate of the deaths at a global level. The risk of deadly myocardial infraction grows because of diabetes which even causes the development of heart failure.
Objective:
The objective of this study was to understand and study the effect of glycyrrhizin on diabetes suffering rats with myocardial remodeling.
Materials and methods:
Streptozotocin was used for induction of diabetes, and 8-12 weeks later, the assessment of inflammation, fibrosis, and cardiac damage was evaluated. Histopathological analysis and immunohistochemistry was performed to analyze the effect in various groups. Western blotting was performed to understand the proteins expressed in diabetes, and also, their expression was noted in treatment groups.
Results:
There was a significant rise in TNF-α, dense fibrosis, and collagen deposits in the STZ diabetes group. The effects of hyperglycemia were significantly improved in the glycyrrhizin-treated group. DAPI, BrDu, and caspase staining was also performed to understand apoptosis in tissues where the diabetic groups reported significant apoptosis, while the effects were significantly lower in the treated group.
Conclusion:
All the observations indicate that glycyrrhizin has cardioprotective action in diabetic rats with myocardial remodeling and is due to the inhibition of the NF-κB signaling pathway in the myocardial layer.
