OBJECTIVE: To study the effects of volatie oil of Schizonepeta tenuifolia Briq herb and Saposhnikovia divaricata Schischke root (OSS) on proinflammatory cytokine expression and regulation in rats. METHOD: OA and LPS were injected intravenously to rats to develop acute lung injury (ALI). The rats were treated with OSS (45.19 microL kg(-1)). The pathological sections of lung tissue were prepared and observed in acute lung injury rats. The expression of nuclear factor-kappa B p65 (NF-kappaB p65), intercellar adhesion molecule CD54, and NF-kappaB p65 mRNA were determined in lung cells. RESULT: volatie oil of Schizonepeta tenuifolia Briq herb and Saposhnikovia divaricata Schischke root significantly inhibited the expression of CD54, the activation of NF-kappaB p65, and the transcription of NF-kappaB p65 mRNA. CONCLUSION: OSS can reduce the expression of CD54 and NF-kappaB p65 protein synthesis, which may be its anti-inflammatory molecular mechanisms.
