Effects of the Folk Medicinal Plant Extract Ankaferd BloodStopper on the Healing of Colon Anastomosis: An Experimental Study in a Rat Model

Determination of the Effects of Ankaferd Wound Dressing on the Wound Healing Process in Rats

Objectives

The effects of a composite nanofiber wound dressing material consisting of a polyvinylidene alcohol and polyvinylidene pyrrolidone polymer mixture with a hemostatic agent doped with Ankaferd Blood Stopper (ABS) on the healing of experimentally induced dermal wounds in rats were examined.

Materials and Methods

Rats were divided into 4 groups (n= 6). Histological material was examined on tissues taken from the wound site, whereas total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI) analyses were performed on blood samples taken from the cardia. The material that was produced had hydrophilic properties, and both the ABS-doped and-undoped forms of the material positively affected wound healing.

Results

In the histopathological examinations, macroscopic evaluations revealed a statistically significant difference between the groups in terms of wound diameter, reepithelialization, and inflammation formation (p= 0.019). In parallel with wound healing and histological outcomes, TAS values increased in the ABS-doped groups, and TOS and OSI values decreased in the wound dressing groups (p < 0.05).

Conclusion

It was concluded that the ABS-dopped dressing did not have a negative effect on wound healing, it accelerated healing, and it could be used effectively and safely to treat skin injuries. However, further studies are needed to evaluate the clinical and histopathological benefits and potential adverse effects of wound dressings produced using ABS-doped polymers on wound healing.

Comparison of the efficacy of growth factor collagen and antibiotic collagen on colon anastomosis in experimental animals with peritonitis

INTRODUCTION

In spite of advances in surgical techniques, the significance of anastomosis leak continues in colorectal surgery. There is no ideal method in spite of all studies and technical advances in this field. Our aim of this study was to use fibroblast growth factor collagen (FGF-C) and antibiotic collagen (AB-C) to increase the rate of anastomosis healing in experimental animals with peritonitis.

METHODS

This animal experimental study received ethics committee approval. The animals were divided into three groups of seven animals each; the first group was control, the second group was the fibroblast growth factor collagen group, and the third group was the antibiotic collagen group. Under anesthesia, more than 50% of the colonic lumen was opened 4-5 cm distal to the ileocecal junction to create a defect. Twenty-four hours later, primary anastomosis was performed. The second group had the anastomosis line covered with a cover containing FGF-C. The third group had the anastomosis line covered by material containing AB-C. The experiment was concluded on the postoperative 7th day, and the anastomosis burst pressure, tissue hydroxyproline level, and histopathological assessment were performed.

RESULTS

Though the burst pressure was higher in the experimental groups, it was not statistically significant. In the second and third groups, vascular proliferation and fibroblastic activity appeared to be better than in the control group. Hydroxyproline values were statistically significant in the experimental groups compared to the control group.

CONCLUSION

FGF-C and AB-C may have potential utility in anastomosis healing, especially in those susceptible to infection due to anastomosis leak.
