Article Abstract
Objective: (Lam.) Benth. (Bignoniaceae) syn. (Jacq. DC) is a tropical plant that is native to tropical Africa. The aim of this study was to determine if a methanolic extract prepared from (KAE) can promote wound healing in treated human normal epidermal keratinocyte (HaCaT) cells and human normal foreskin fibroblast cell line (BJ) cells compared with untreated cells.
Method: Experimental steps included: the methanolic extraction of the leaf and fruit of the plant; the preparation of HaCaT and BJ cell lines; cell culture with a stable tetrazolium salt-based proliferation assay; and the evaluation of the wound healing effect of KAE (2μg/ml) in BJ and HaCaT cells. The phytochemical contents of KAE were determined using liquid chromatography quadrupole time-of-flight mass spectrometry.
Results: The following molecules were identified as being present in the KAE, among others: cholesterol sulfate; lignoceric acid; embelin; isostearic acid; linoleic acid; dioctyl phthalate; arg-pro-thr; 15-methyl-15(S)-PGE1; sucrose; benzododecinium (Ajatin); and 9-Octadecenamide (oleamide). KAE effected faster wound healing in treated cells compared with untreated cells for both cell lines. HaCaT cells that had been mechanically injured and treated with KAE healed completely in 48 hours compared with 72 hours for untreated HaCaT cells. Treated BJ cells healed completely in 72 hours compared with 96 hours for untreated BJ cells. Concentrations of KAE up to 300μg/ml had a very low cytotoxic effect on treated BJ and HaCaT cells.
Conclusion: The experimental data in this study support the potential of KAE-based wound healing treatment to accelerate wound healing.

Wound healing is a complex, tightly regulated process involving a range of enzymes, growth factors, and cytokines that coordinate cellular activities essential for tissue repair and wound closure. However, in cases of extensive or severe injury, the intrinsic repair mechanisms are often insufficient, underscoring the need for advanced therapeutic strategies to accelerate healing and minimize scar formation. Electrically conductive hydrogels (ECHs), combining the advantageous properties of hydrogels with the physiological and electrochemical characteristics of conductive materials, present a safer and more convenient alternative to traditional electrode-based electrical stimulation (ES) for treating chronic and nonhealing wounds.

Wound infections challenge clinical medicine, and developing novel therapies is critically important in overcoming antimicrobial resistance and an off-balanced immune microenvironment. Electrical stimulation as a biocompatible, easy-to-operate, and controllable technique has great potential in eradicating pathogens and modulating the immune system. However, safe and soft platforms that integrate both bactericidal and immunological modulatory effects of electrical stimulation are rarely reported.

Background: Charcot foot is a debilitating complication of peripheral neuropathy and is primarily associated with diabetes, leading to structural damage, ulceration, and osteomyelitis. Pulsed electromagnetic field (PEMF) therapy is a promising treatment modality for wound healing and bone metabolism.
Objective: To evaluate the efficacy of PEMF therapy in promoting bone growth and ulcer healing in patients with Charcot foot ulcers.
