1、百賽諾(雙環(huán)醇片)保肝抗炎作用研究進(jìn)展,肝細(xì)胞損傷和肝臟炎癥壞死,肝細(xì)胞損傷是各型肝病共同的病理基礎(chǔ)及共同表現(xiàn); 導(dǎo)致肝細(xì)胞變性、凋亡、壞死最終導(dǎo)致肝衰竭。肝臟炎癥壞死及其所致的肝纖維化是疾病進(jìn)展的主要病理學(xué)基礎(chǔ)。在對(duì)病因治療的基礎(chǔ)上有效控制肝組織炎癥,有可能減少肝細(xì)胞破壞和延緩肝纖維化的發(fā)展。,轉(zhuǎn)氨酶的功能及臨床意義,血清氨基轉(zhuǎn)移酶以肝臟含量最為豐富,臨床中用于血清學(xué)診斷主要為: 谷丙轉(zhuǎn)氨
2、酶 (ALT):肝>腎>心>肌肉 谷草轉(zhuǎn)氨酶 (AST):心>肝>肌肉>腎在肝內(nèi),ALT全部存在于肝細(xì)胞漿中;AST 80%存在于線粒體內(nèi),20%在胞漿內(nèi)。 當(dāng)肝細(xì)胞發(fā)生炎癥、壞死、中毒等造成肝細(xì)胞受損時(shí),轉(zhuǎn)氨酶會(huì)釋放入血液,血清轉(zhuǎn)氨酶升高。ALT水平可以比較敏感地監(jiān)測(cè)到肝臟是否受到損害。當(dāng)肝細(xì)胞嚴(yán)重?fù)p傷波及線粒體時(shí)AST也會(huì)進(jìn)入血中。,肝損傷的基本治療策略,病因治療:
