It is estimated that 15 percent of individuals with diabetes mellitus suffer from diabetic ulcers worldwide. The aim of this study is to present a non-thermal atmospheric plasma treatment as a novel therapy for diabetic wounds. The plasma consists of ionized helium gas that is produced by a high-voltage (8 kV) and high-frequency (6 kHz) power supply. Diabetes was induced in rats via an intravascular injection of streptozotocin. The plasma was then introduced to artificial xerograph wounds in the rats for 10 minutes. Immunohistochemistry assays was performed to determine the level of transforming growth factor (TGF-β1) cytokine. The results showed a low healing rate in the diabetic wounds compared with the wound-healing rate in non-diabetic animals (P < 0.05). Moreover, the results noted that plasma enhanced the wound-healing rate in the non-diabetic rats (P < 0.05), and significant wound contraction occurred after the plasma treatment compared with untreated diabetic wounds (P < 0.05). Histological analyses revealed the formation of an epidermis layer, neovascularization and cell proliferation. The plasma treatment also resulted in the release of TGF-β1 cytokine from cells in the tissue medium. The findings of this study demonstrate the effect of plasma treatment for wound healing in diabetic rats.

In this case series, ten patients with plaque-type psoriasis were treated with Hypericum perforatum ointment. The hypericum ointment was applied to one side of each patient's body and the vehicle to the opposite side twice daily for 4 weeks in a single blinded manner. Modified psoriasis area severity index (PASI) scores were significantly lowered where the formulated ointment had been applied. In determining PASI scores, three factors, erythema, scaling and thickness, were evaluated; all were significantly lower where the formulated ointment had been applied (P = 0.01, P = 0.004, P = 0.04). Hypericum perforatum ointment applied twice daily may be effective in reducing PASI scores in mild plaque-type psoriasis, however, further larger studies need be conducted to achieve a more conclusive result.
