Abstract

The application of atmospheric pressure low-temperature plasma (LTP) in medical treatment has received extensive attention owing to its redox regulatory and anti-inflammatory properties. Nephrotoxicity due to oxidative stress and inflammation is the main adverse effect of cisplatin. In the present study, rats with cisplatin-induced nephrotoxicity were treated with LTP to investigate its potential protective effect. The results showed that LTP treatment has multiple protective effects on cisplatin-induced nephrotoxicity. It significantly improved clinical indicators such as survival rate, water intake, food intake, body weight, and mobility, as well as physiological indexes such as reduced renal index and levels of serum urea, creatinine, and total bilirubin; pathological indicators such as reduced tubular injury, inflammatory infiltration, tubulointerstitial fibrosis, and apoptosis; cell survival indicators such as decreased protein levels of Caspase-3 and Bax and increased Bcl-2; anti-oxidation status such as reduced malondialdehyde content and increased activities of catalase, superoxide dismutase, and glutathione peroxidase; and reduced inflammatory factors such as TNF-α in kidney tissues. Specially, LTP treatment did not influence the anticancer effect of cisplatin as observed in the solid tumor mouse model established by subcutaneously inoculating H22 cells. Moreover, LTP did not influence the physiological and pathological indicators of normal rats, suggesting its biological safety. In conclusion, LTP can protect against cisplatin-induced nephrotoxicity through its anti-oxidation, anti-inflammation, and anti-apoptosis effects, without influencing the anticancer effect of cisplatin.
