Resumo: |
One of the complications of diabetes is the difficulty of wound healing. Several studies are being conducted in order to find a drug to optimize healing while taking a low cost. Calendula officinalis in homeopathic materia medica is cited as a healing agent, but no studies in the literature evaluating its effect on wounds in diabetic patients has been peeformed. Chitosan is a biopolymer that has anti-inflammatory, antibacterial, and antioxidant potential and helps in the healing process. The objective of this study was to evaluate and compare the effect of Calendula officinalis 6 CH and Chitosan Spray on the healing of skin wounds in diabetic rats. For this, we used 54 female rats randomly assigned into three groups (CG, GH, and GQ) 18 animals each satisfaction. The animals were treated according to the group to which they belonged: the CG with 0.9% saline, the GH with Calendula officinalis 6 CH, and GQ with Chitosan Spray. Each group was divided into three subgroups (n = 6) corresponding to periods of microscopic evaluation (three, seven, and 14 days). The rats were diabetes- induced by intraperitoneal application of Aloxana (120mg / kg) and then anesthetized for holding the punch of 9.0 mm in the dorsal thoracic vertebrae. Macroscopic and microscopic evaluations were performed. Macroscopically, animals treated with Calendula 6 CH and Chitosan Spray had their wounds healed in a shorter time when compared to the CG. Microscopically, we observed that the Calendula 6 CH was able to promote increased recruitment of mononuclear cells present in fibroplasia in the initial healing stage and promote formation of thick dense connective tissue and organized at the end of 14 days, demonstrating superiority to the control group and to the Chitosan group. The Chitosan Spray was effective and superior in optimizing wound healing compared to the control group. |
