血液辐射前后SOD、GSH－PX及LPO含量的变化

观察２０例心脏病患者血液辐射前后红细胞ＳＯＤ、全血ＧＳＨ－ＰＸ及血浆ＬＰＯ变化，并计算ＳＯＤ／ＬＰＯ比值，结果表明：血液辐射前后ＧＳＨ－ＰＸ、ＬＰＯ及ＳＯＤ／ＬＰＯ无明显改变，但辐射后ＳＯＤ活性明显升高，提示自血辐射疗法的作用机制可能部分是通过激活ＳＯＤ活性，抑制超氧阴离子产生，减少脂质过氢化损伤发挥治疗作用。

糖尿病大鼠视网膜组织抗氧化机能状况的动态观察

目的探讨糖尿病大鼠视网膜组织的抗氧化机能状况.方法将30只Wister大鼠分为实验组和正常对照组.实验组用链脲佐菌素(streptozotocin,STZ)诱发糖尿病.发病后4、6和12周对两组大鼠血中自由基(FR)含量、视网膜组织中超氧化物歧化酶(SOD)、过氧化氢酶(CAT)和谷胱甘肽过氧化物酶的活性(GSH-Px)及脂质过氧化物(LPO)水平进行了检测.结果各实验时点视网膜组织中SOD和CAT活性则显着低于对照组.糖尿病大鼠血中FR含量和视网膜组织中LPO水平及GSH-Px活性明显高于对照组大鼠,随病程的延长这些改变更明显.结论糖尿病大鼠血和视网膜组织中的抗氧化机能处于低下状态,这些变化可能在糖尿病视网膜病变、糖尿病血管性并发症的发生发展中起着重要作用.     

针灸对脑外伤患者血清中SOD、MDA、LPO水平变化的研究

目的:探讨针灸对急性脑外伤患者血清中的SOD、MDA、LPO水平变化的影响.方法:将54例外伤患者随机分成2组,对照组27例,常规西医治疗;治疗组27例,在常规西医治疗(同对照组)加用针刺疗法.治疗组于伤后第3天进行针灸治疗.在针灸治疗前一天与针灸治疗10天后抽取静脉血5ml,对照组在同一时间(第2天与第13天)抽取静脉血5ml,分测SOD、MDA、LPO的含量进行对照比较.结果:两组病人伤后3天到13天,机体抗拉化酶SOD明显上升,MDA、LPO均明显下降,其中针灸组的MDA、LPO含量的下降值明显低于对照组,P＜0.01,SOD含量的增加值明显高于对照组,P＜0.01.结论:针灸有助于脑外伤的恢复.     

淫羊藿有效成分抗氧化作用研究

实验结果发现巫山淫羊藿多糖多相脂质体(ESPS)能明显提高老龄动物红细胞及肝组织中SOD的活性,提高老龄小鼠红细胞GSH-Px的活性;能明显降低老龄动物血清及肝组织中LPO的含量,降低老龄小鼠心肌脂褐质的含量。     

补肾填精方对老龄大鼠脑细胞脂褐素及外周血SOD.LPO含量的影响观察

补肾填精方具有降低老龄鼠脑细胞脂褐素的含量，改善外周血ＳＯＤ、ＬＰＯ浓度的作用，有一定的延缓衰老的作用。     

固本健脑液对人胚肺二倍体成纤维细胞寿命及LPO含量的影响

固本健脑液系以恩施州道地中药材－中国板党为主，辅以健脾，补肾，等中药加工而成的复方制剂本实验观察了固体健脑液对人胚肺二倍体成纤维细胞传代次数及过氧化脂质含量的影响。结果表明，２０－２００ｐｐｍ的固本健脑液能显延长细胞寿命和降低细胞ＬＰＯ的含量，且明显优于维生素Ｅ对照组的治疗作用。     

Herbal medicines for the prevention of alcoholic liver disease: A review

Ethnopharmacological relevance

Long-term excess alcohol exposure leads to alcoholic liver disease (ALD)—a global health problem without effective therapeutic approach. ALD is increasingly considered as a complex and multifaceted pathological process, involving oxidative stress, inflammation and excessive fatty acid synthesis. Over the past decade, herbal medicines have attracted much attention as potential therapeutic agents in the prevention and treatment of ALD, due to their multiple targets and less toxic side effects. Several herbs, such as Cnidium monnieri (L.) Cusson (Apiaceae), Curcuma longa L. (Zingiberaceae) and Pueraria lobata (Willd.) Ohwi (Leguminosae), etc., have been shown to be quite effective and are being widely used in China today for the treatment of ALD when used alone or in combination.

Aim of the review

To review current available knowledge on herbal medicines used to prevent or treat ALD and their underlying mechanisms.

Materials and methods

We used the pre-set searching syntax and inclusion criteria to retrieve available published literature from PUBMED and Web of Science databases, all herbal medicines and their active compounds tested on ALD induced by both acute and chronic alcohol ingestion were included.

Results

A total of 40 experimental studies involving 34 herbal medicines and (or) active compounds were retrieved and reviewed. We found that all reported extracts and individual compounds from herbal medicines/natural plants could be beneficial to ALD, which might be attributed to regulate multiple critical targets involved in the pathways of oxidation, inflammation and lipid metabolism.

Conclusions

Screening chemical candidate from herbal medicine might be a promising approach to drug discovery for the prevention or treatment of ALD. However, further studies remain to be done on the systematic assessment of herbal medicines against ALD and the underlying mechanisms, as well as their quality control studies.
