Effect of Ankaferd Blood Stopper on Skin Superoxide Dismutase and Catalase Activities in Warfarin-Treated Rats

The Role of Chronotype of Patients and Cryoexrtact of Placenta in the Activity of Antioxidant Enzymes in Facial Scar

BACKGROUND: The chronotypical features of people have a significant impact on the course of reparative processes in the patient’s body. Understanding the mechanisms of influence on the course of reparative skin regeneration after planned surgical interventions within the maxillofacial tissues can contribute to improving the provision of medical care to such patients. AIM: The study was aimed to determine role of chronotype of patients and cryoexrtact of placenta in the activity of antioxidant enzymes in facial scar. METHODS: In our study, 60 patients (36 males and 24 females) of the Department of Maxillofacial Surgery of the Poltava Regional Clinical Hospital, Ukraine, aged from 18 to 68 years, who underwent inpatient treatment for planned surgical interventions of the maxillofacial area, were enrolled. At the time of the study, the patients did not have concomitant diseases, but if necessary, all patients could consult by other specialists. The practical section was carried out between September 2019 and August 2021 as follow. According to our study, 60 patients were divided depending on the type of chronotype, which was determined by the Horn-Ostberg questionnaire in Stepanova’s modification and the type of using treatment taking into account different ways of using of cryoextract of placenta. The activities of superoxide dismutase and catalase were determined on the 90th, 180th, and 360th days of observation in the forming scar tissue. We used the method of Chevari et al. to determine the activity of superoxide dismutase. Catalase activity in homogenates of scar tissue was determined according to the method of M.A. Koroliuk. RESULTS: It was noted that the enzymatic activity of catalase in the scar homogenate is characterized by a lower dynamics of changes than the activity of superoxide dismutase. Positive dynamics were noted under the conditions of use in the treatment protocol of placenta cryoextract, which was more pronounced in patients with a morning chronotype. CONCLUSIONS: The most significant changes were observed in the studied indicators of antioxidant protection in patients of the morning chronotype who underwent intrawound administration of cryoextract of the placenta in combination with electrophoresis of this remedy against the background of a standard treatment protocol, especially at earlier terms after surgical treatment.

Comparison of hemostatic efficacy of topical Ankaferd Blood Stopper on heparinized and nonheparinized rats in bleeding related to liver injury

PURPOSE

In this study, hemostatic efficacy of Ankaferd Blood Stopper (ABS), a new generation hemostatic agent, was compared in the presence of heparin effect.

METHODS

Forty-eight Wistar albino rats were divided into two main groups as heparinized and nonheparinized, and these two main groupswere divided into six subgroups as control, Surgicel and ABS (n = 8). Grade 2 liver injury was performed on rats as standard. All groups were compared in terms of weight, laceration surface area, prothrombin time (PT), activated partial thromboplastin time (aPTT), international normalized ratio (INR), bleeding time, bleeding amount, hemoglobin (Hb) levels, macroscopic and microscopic reactions to the agent used.

RESULTS

Whereas there was no statistically significant difference between weight, laceration surface area, PT, INR and preoperative Hb values in the heparinized and nonheparinized groups, postoperative Hb, bleeding time, bleeding amount and aPTT values were statistically different (p < 0.05). In the heparin-hemostat interaction, the ABS group had the lowest bleeding in the heparinized group in terms of the amount of bleeding compared to the control and Surgicel groups (F = 0.764; p = 0.047). In macroscopic and microscopic comparison, there was no difference between the groups in terms of cell necrosis andfresh bleeding (p > 0.05), it was found that the Surgicel group had statistical significantly higher reaction scores (p < 0.05) than the other groups in terms of other parameters.

CONCLUSIONS

Ankaferd Blood Stopper can be safely and effectively used in surgical practice and in patients with additional diseases requiring heparinization, since it causes minimal reaction in the liver and decreases the amount of bleeding especially in the heparinized group.

Effects of Ankaferd BloodStopper on dermal healing in diabetic rats

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

ABS's benefits in the control group seemed to lose their effectiveness under STZ medication.
