Wound healing efficacy of novel ayurveda formulation- Pentabark Kashaya: In wistar rats using excision wound model- an in vivo study
Abstract
Background: Wound healing plays a major concern in the field of surgery as it requires uneventful healing. Management aims towards prevention of infection and to accelerate healing. Acharya Sushruta has given more emphasis on Vrana (wound) and its chikitsa (treatment). Many antiseptic agents which prevent infection are widely used but have no role in accelerating the healing process and are cytotoxic, deleterious to wound healing. In this regard an innovative polyherbomineral formulation Pentabark Kashaya (PK)was formulated to assess acute dermal toxicity and woundhealing activity. Objective: To explore the wound healing efficacy of novel Ayurveda Formulation i.e Pentabark Kashaya in Wistar rats using the excision wound model. Materials and method: Acute dermal toxicity study was carried out on five female Wistar rats by following the OECD guideline 434 and signs of toxicity were assessed for the period of 14 days. Wound healing activitywas assessed on the excision wound model. 18 male Wistar rats were procured for the study and divided into three groups (n = 6 in each group). The test group was treated with application of PK, standard group with Povidone iodine solution 5% and control group with distilled water. The parameters assessed were epithelialization period, wound contraction rate, wound closure day and swab test for microbial load for the period of 21 days. Statistical analysis was done by using one way ANOVA and Tukeys HSD to assess changes in between three groups at each time point. Results: No signs of acute dermal toxicity were seen, which proved that PK is safe for application. Significant results were seen in the parameters of wound healing like period of epithelialization and wound closure day. Percentage of wound contraction rate was increased in test group when compared to other groups. Histopathology of skin showed marked changes in re-epithelialization, dermal fibroblast, dermal fibrocytes in test group when compared to control group. Conclusion: PK is safe for application and it is effective in wound healing.Clinical Trial Registration No.: Not applicable.
