The present study examined the protective effect of the ethanol extract of Sarcopyramis nepalensis (EESN) on agents-induced hepatotoxicity in mice and the possible mechanism. Acute liver injury was induced by administration of either CCl4 or D-GalN. The animals were divided into 5 groups in terms of different treatment: normal group, CCl4 or D-GalN group, silymarin or bifendate group, low dose EESN group (10 mg/kg) and high dose EESN group (30 mg/kg). Liver function was evaluated by detecting the levels of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST). The oxidize stress markers were measured, including malondialdehyde (MDA), glutathione peroxidase (GSH) and superoxide dismutase (SOD). Liver tissues were histopathologically examined by hematoxy-lin-eosin (H&E) staining. The acute toxicity study revealed that there was no toxicity of EESN at the dose of 5 g/kg in mice. The levels of ALT and AST in serum, and the MDA level in live tissues were significantly increased and the activities of SOD and GSH substantially decreased in mice after CCl4 or D-GalN treatment. These biochemical and oxidize stress markers were profoundly improved after treatment with EESN at different doses, which was similar to the results of silymarin or bifendate treatment. The histophathological examination revealed the significant improvement in the pathological changes of the liver in EESN-treated mice as compared to those in CCl4 or D-GalN group. It was concluded that EESN possesses potential antioxidant and hepatoprotective properties and has therapeutic potential for liver diseases. 相似文献

摘 要中东呼吸综合征(MERS)是由中东呼吸综合征冠状病毒(MERS-CoV)引起的急性呼吸道传染病。MERS-CoV是继SARS冠状病毒(SARS-CoV)之后发现的一种具有高致死率的新型病毒,可由单峰骆驼传染给人类。目前,临床尚无抗MERS-CoV的特效药物。抗MERS-CoV的药物开发策略主要是借鉴抗SARS-CoV药物的开发经验,包括疫苗,抗体,小分子化合物快速筛选等。本文结合临床治疗及动物模型对MERS治疗药物的研究进展进行综述,旨在为该病新型疫苗和抗病毒药物的研发提供借鉴。 相似文献

摘 要 目的:分析利巴韦林不良反应/事件(ADR/ADE)发生的一般规律和特点,为临床安全用药提供依据。方法:采用回顾性研究方法,对2006年6月~2018年6月湖北省药品(医疗器械)ADR监测中心数据库中收集的1 071例利巴韦林ADR/ADE报告的患者人口学特征、用药原因、联合用药情况和不良反应受累系统/器官分布及临床表现等进行统计和分析。结果:利巴韦林引起的ADR/ADE涉及7种剂型,注射液占比最多(84.12%);ADR/ADE在各年龄组段均有分布,男性略多于女性;所致ADR/ADE临床表现复杂多样,但主要为皮疹和过敏样反应,严重者可出现过敏性休克和血液系统损害。 结论:利巴韦林致ADR/ADE个体差异大,临床用药时应严格掌握适应证,尽量避免不合理的联合用药,以减少ADR/ADE的发生。 相似文献
