Effects of volatie oil of Schizonepeta tenuifolia Briq herb and Saposhnikovia divaricata Schischke root on proinflammatory cytokine expression and regulation / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>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.</p><p><b>METHOD</b>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.</p><p><b>RESULT</b>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.</p><p><b>CONCLUSION</b>OSS can reduce the expression of CD54 and NF-kappaB p65 protein synthesis, which may be its anti-inflammatory molecular mechanisms.</p>
