Effect of the traditional Chinese medicines Chan Su,Lu-Shen-Wan,Dan Shen,and Asian ginseng on serum digoxin measurement by Tina-quant (Roche) and Synchron LX system (Beckman) digoxin immunoassays

Chan Su, Lu-Shen-Wan, Dan Shen, and Asian ginseng are traditionally used to treat a number of conditions, including cardiovascular disease. All of these traditional Chinese medicines exhibit cardioactive properties. Digoxin is a cardioactive drug with a narrow therapeutic range (0.8-1.9 ng/mL). A patient taking digoxin may also take these Chinese medicines for their cardiotonic effects. Moreover, the active components of these medicines that are responsible for cardiotonic effects bear structural similarities to digoxin. Therefore, we studied the potential interference of these Chinese medicines with two digoxin immunoassays--the Tina-quant (Roche Diagnostics) and the Beckman (Synchron LX system)--and compared the values with the fluorescence polarization immunoassay (FPIA; Abbott Laboratories). When very small amounts (2-5 microL) of aqueous extract of Chan Su or Lu-Shen-Wan were added to drug-free serum, we observed high digoxin-like immunoreactivity with the FPIA. In contrast, when ethyl acetate extract of Dan Shen or microliter amounts of ginseng extract were added to drug-free serum, we observed modest digoxin-like immunoreactivity with the FPIA, but no apparent digoxin activity with the Roche and Beckman digoxin immunoassays. When aliquots of a digoxin pool prepared from patients receiving digoxin were supplemented with these Chinese medicines, we observed the most significant interference with the FPIA. The presence of endogenous digoxin-like immunoreactive substances can have additive effects with these Chinese medicines and falsely increase apparent digoxin levels by the FPIA. On the other hand, the Roche and Beckman assays were free from interference from DLIS but showed significant interference from Chan Su and Lu-Shen-Wan. We conclude that the FPIA showed the most significant interference from all four of the Chinese medicines we studied. However, the Roche and Beckman assays showed no interference from two (Dan Shen and Asian ginseng) of the four Chinese medicines we studied.     

明代六部综合性医书的传日及其影响

明代传日医书众多,以《医书大全》、《南北经验医方大成》、《玉机微义》、《医学正传》、《医学入门》、《万病回春》等综合性医书,传播最快,影响最大。它们促进了16世纪以降日本开始对中国医籍的大量翻刻;为日本当时医师培养提供了便捷教本;丰富了道三学派的理论与实践,从而为日本医学中兴增添了砖瓦。

大黄NFDA1虫丸对肺纤维化大鼠形成阶段的影响

目的:探索大黄虫丸对肺纤维化形成阶段的干预作用机制。方法:将48只普通级健康wistar大鼠用平阳霉素复制肺纤维化模型大鼠后,分为正常对照组、模型对照组、大黄虫丸组和强的松对照组。大黄虫丸剂量1.2 g.kg-1,从第14 d开始按15 mL.kg-1体重ig,造模28 d后处死,测定、比较各组大鼠血清和支气管肺泡灌洗液(bronchoalveolar lavage fluid,BALF)中超氧化物歧化酶(superoxide dismutase,SOD)活性及丙二醛(malondialdehyde,MDA)含量。结果:模型组大鼠血清及BALF中SOD活性低于正常对照组、MDA含量高于正常对照组,大黄虫丸组SOD活性均高于模型组,MDA含量均低于模型组;大鼠BALF中SOD活性、MDA含量与血清SOD活性、MDA含量呈正相关。结论:大黄虫丸有抑制模型大鼠肺及血清中SOD活性下降及MDA含量增高的作用;血清SOD活性和MDA含量可间接反映肺部脂质过氧化与抗氧化水平。
