Investigation of anti-inflammatory effects of oxygen nanobubbles in a rat hydrochloric acid lung injury model.
2020
Aim: To investigate the anti-inflammatory effect of oxygen nanobubbles (ONBs) in an acute lung injury rat model. Materials & methods: In a rat hydrochloric acid lung injury model, ONB fluid was administered intravenously in the ONB group (n = 6) and normal saline was administered in the control group (n = 6). 4 h later, arterial partial pressure of oxygen (PaO2), mean arterial pressure and plasma inflammatory cytokines were measured. Results: There were no significant differences in the PaO2, mean arterial pressure or TNF-α and IL-6 levels between the two groups. Conclusions: No anti-inflammatory effect could be confirmed at the present ONB dose in the rat model of acute lung injury.
