Assessment of Wound Healing Potential of Passiflora foetida L. Stem in Streptozotocin-Induced Diabetes Mellitus
Abstract
The study investigates the wound healing potential of Passiflora foetida L. stem in a Streptozotocin (STZ)-induced diabetic rat model. Diabetes mellitus is a major contributor to delayed wound healing, and traditional plant-based treatments offer promising alternatives. In this experiment, diabetic wounds were induced in Wistar albino rats using STZ, and the healing process was evaluated following the topical application of Passiflora foetida L. stem extracts. The rats were divided into various treatment groups, with one group receiving the extract, while others were treated with a standard wound healing agent or a control. Parameters such as wound closure rate, histopathological changes, and biochemical markers associated with healing (collagen content, inflammatory mediators, and antioxidant levels) were assessed over a period of time. The results demonstrated a significant improvement in wound healing in the group treated with Passiflora foetida L. stem extract, showing accelerated wound closure and enhanced tissue regeneration compared to the control group. These findings support the traditional use of Passiflora foetida for wound healing and suggest that it may possess therapeutic potential for diabetic wound care. Further studies to isolate the active compounds and evaluate their mechanisms of action are warranted.

Introduction
Diabetes mellitus is a chronic metabolic disorder characterized by elevated blood glucose levels and is associated with a range of complications, including impaired wound healing. In diabetic patients, wounds, particularly diabetic ulcers, often heal at a slower rate due to factors such as poor circulation, immune dysfunction, and prolonged inflammation. The delayed healing of wounds in diabetic individuals poses a significant challenge to both patients and healthcare systems, necessitating the exploration of new therapeutic strategies.
Passiflora foetida L., a species of the passionflower, is traditionally used in various cultures for its medicinal properties, including wound healing. The plant is known for its diverse phytochemical profile, which includes alkaloids, flavonoids, and terpenoids, all of which have demonstrated potential biological activities such as antioxidant, anti-inflammatory, and antimicrobial effects. Despite its historical use, scientific evidence supporting its efficacy in wound healing, particularly in diabetic conditions, remains limited.
Streptozotocin (STZ)-induced diabetes is a widely used experimental model that mimics the pathophysiological features of type 1 diabetes in humans, including delayed wound healing. This model provides a valuable platform to investigate the effectiveness of various therapeutic agents, including plant extracts, in enhancing the wound healing process.
This study aims to assess the wound healing potential of Passiflora foetida L. stem in STZ-induced diabetic rats. By evaluating parameters such as wound closure rate, histopathological changes, and biochemical markers of healing, we aim to provide scientific evidence supporting the traditional use of Passiflora foetida for treating diabetic wounds and to identify its potential as an alternative therapeutic option for managing diabetic ulcers.
Conclusion
This study demonstrates that the ethyl acetate and ethanol extracts promote faster wound healing in diabetic patients. The findings indicate that these extracts may positively influence various phases of wound healing. It is likely that the improved wound healing in diabetic rats is attributed to the hypoglycemic effects (Rosenthal SP, 1968).
