The effect of low-dose photodynamic therapy using the photosensitizer chloroaluminum phthalocyanine on a scratch wound model in skin fibroblasts.

Different approaches on wound healing have been developed over the years but they suffer from high costs and adverse effects for the patients. The current paper was designed to study low dose PDT, a novel healing approach, in an in vitro fibroblasts wound healing model. Chloroaluminum phthalocyanine (AlClPc) was used as photosensitizer and was activated by a red diode laser at 661 nm.

Octenidine Versus Dispase Gels for Wound Healing After Cryosurgery Treatment in Patients with Basal Cell Carcinoma.

For a specific group of patients with basal cell carcinoma (small, low risk), cryosurgery could be the suggested treatment, which results in the formation of an ulcer in the lesion area. The proteolytic enzymes' contribution to the wound healing is an ongoing research goal. Preclinical animal experiments in the Laboratory of the Pharmaceutical Technology Department of the National and Kapodistrian University of Athens have showed that a dose of 5 U/mL of dispase gel after the formation of tissue rashes, significantly promoted wound healing.

The effects of low power laser light at 661 nm on wound healing in a scratch assay fibroblast model.

Wound treatment, especially for chronic and infected wounds, has been a permanent socio-economical challenge. This study aimed to investigate the ability of red light at 661 nm to accelerate wound healing an in vitro wound model using 3T3 fibroblasts. The purpose is further specified in clarifying the mechanisms of wound closure by means of intracellular ROS production, proliferation and migration of cells, and cellular orientation.
