IntroductionDiabetes mellitus (DM) is a chronic, life-long metabolic disease occurring worldwide. Affected individuals require continuous follow-up and suffer numerous disease-related complications. The high levels of blood glucose that characterise DM contribute to an increase in free radical production, enhanced oxidative stress, and changes in antioxidant capacity (1-3).Streptozotocin (STZ) is the chemical agent most frequently used to induce experimental diabetes in animal models. By binding to glucose receptors in the plasma membrane, STZ blocks glucose-induced insulin secretion (2,3) and alters blood insulin and glucose concentrations.Among the many effects of free radical production is lipid peroxidation (LPO). Oxidation of membrane polyunsaturated fatty acids disrupts cell structure and function and induces cytotoxic, hepatotoxic, mutagenic, and genotoxic effects related to the release of aldehydes (4,5).The tripeptide glutathione (GSH) is found in the cells of all organisms. In humans, GSH concentrations are highest in the liver; in hepatocytes, GSH accounts for 90% of nonprotein sulfhydryl groups. As an important reducing agent and antioxidant, GSH maintains the cellular oxidoreduction balance and protects cells against the toxic effects of oxidants, whether of endogenous or exogenous origin (5-7).Ankaferd BloodStopper (ABS) (Ankaferd Health Products Ltd., İstanbul, Turkey) is a medicinal extract from the plants Thymus vulgaris, Glycyrrhiza glabra, Vitis vinifera, Alpinia officinarum, and Urtica dioica (7,8). ABS is not only an effective haemostatic agent but also Background/aim: Diabetes mellitus inhibits wound-induced angiogenesis, impairs the wound healing process, and leads to the development of chronic wounds. Ankaferd BloodStopper (ABS) is a new and promising local haemostatic agent. Although the mechanism of ABS-mediated haemostasis is well established, little is known about the associated histological and biochemical tissue reactions. The aim of this study was to evaluate the effects of this new-generation local haemostatic agent on short-term soft-tissue healing in streptozotocin (STZ)-treated rats.
Materials and methods:The 24 Wistar albino rats used in this study were divided into STZ-treated (STZ, n = 12) and nontreated groups (control, n = 12). Four days prior to surgery, rats in the STZ group were subcutaneously administered 60 mg/kg STZ intraperitoneally, while rats in the control group were administered 1 mL saline/kg. An incision was made in the dorsal dermal tissue of all rats, and either ABS or no haemostatic agent (NHAA) was applied to the wound before suturing. All of the rats were euthanised on postoperative day 4. Blood and skin samples were evaluated biochemically and histologically.
Results:The results showed that STZ treatment impaired soft-tissue healing, assessed by measuring glutathione and lipid peroxidation levels. Moreover, while good histological results were obtained in the control group treated with ABS, there were fewer benefits in the STZ-treated group.
Conclusion:AB...
