Pharmacokinetics of amiodarone levels in serum. heart and adi-pose tissues following single or multiple dosing to rats. as well as its relation-ship to anti-arrhythmic activity, were studied. Serum drug levels were found tobe around 0.7μg/ml within 16 hours after a single oral dose of 50mg/kg. and ca.14μg/g of amiodarone was found in the heart tissue 2-8 hours after dosing,which tended to drop later.

Pharmacokinetics of amiodarone levels in serum. heart and adi-pose tissues following single or multiple dosing to rats. as well as its relation-ship to anti-arrhythmic activity, were studied. Serum drug levels were found tobe around 0.7μg/ml within 16 hours after a single oral dose of 50mg/kg. and ca.14μg/g of amiodarone was found in the heart tissue 2-8 hours after dosing,which tended to drop later. During the observation period. drug levels in adiposetissue rose continuously, being 35 times as high as that in the serum 16 hoursafter dosing. Groups of 4 rats were orally given doses of 50 mg/kg daily for up to 3-28days. Drug levels. in the serum and tissue were determined 4 hours following thelast dose. Steady state amiodarone concentrations in serum and heart tissue werefound to have approached on dayill, thus elimination half life was estimatedto be 38-44 hours. The heart/serum drug concentration ratio kept relatively con-stant (i. e., 14-16) within day 3-28, while the fat/serum drug concentrationratio rose continuously. being 106 on day 28. Evidently, owing to the deepperipheral compartment for amiodarone. the adipose tissue was poorly distributedin short durations, while the heart was considered to be the shallow "effect"compartment, thus the heart/serum ratio started to attain equilibrium on day 3.Besides, changes in serum reverse T_3 levels were found to parallel roughly tothose in serum and heart amiodarone levels during the multiple dosing period. Anti-arrhythmic experiments were carried out either in noradrenaline indu-ced rat arrhythmia model or in rats with their coronary arteries being ligated, Although marked anti-arrhythmic effect (principally a significant decrease ofventricular ectopia) was seen half an hour after a single iv. dose of 20 mg/kgin both models. the drug was no more effective 3 hours after the injection,meanwhile drug levels ranged 20. 7-39. 0μg/g in the heart, and 0.79-1.6μg/ml in the plasma. On the contrary, daily oral dose of 20 mg/kg for successivefive days was found to be effective as tested in both models, in spite of thefact that lower drug levels in the heart ranging 10. 0-12.2μg/g were found.The relevance of the above phenomena to the application of clinical therapeu-tic drug monitoring of amiodarone was discussed.

观察了给大鼠单剂及多剂乙胺碘呋酮(简称胺碘酮)后血清、心肌及脂肪组织药浓度的动态变化,并比较了单剂和多剂给药条件下血浆、心肌药浓度和抗心律失常作用的关系。口服单剂50mg/kg后2~8小时血清及心肌药浓度相对平稳,后者约为前者的20倍。脂肪药浓度在16小时内持续上升。大鼠每天口服50mg/kg,服药3~28天期间心肌与血清药浓度比值平稳在14~16范围内,而脂肪与血清药浓度比值持续上升,给药第28天达106。多剂服药期间还看到血清反T_3持续缓慢上升,其变化大致与血清或心肌胺碘酮的变化平行。进行了5批抗心律失常试验,其中3批用结扎冠状动脉模型,2批用去甲肾上腺素模型。发现口服多剂(20mg/kg/d×5)后心肌药浓度虽较静脉注射单剂(20mg/kg)者低,但其抗心律失常作用则较好。对这种现象的机制进行了讨论。

In order to provide scientificbasis for revising the hygiene stan-dard of dust,with the epidemiolo-gic method,we gathered and ana-lysed the 18 years'longitudinal dataof Chengzihe Coal Mine,Jixi. The result showed that it isavailable to use the 20 years dura-tion as a observation duration in stu-dying the relationship between theincidence of anthracosilicosis andthe dust exposure concentration.When we continued observing till the26th year,it showed that at mostonly 0.6 percent degree I anthraco.silicosis occurred....

In order to provide scientificbasis for revising the hygiene stan-dard of dust,with the epidemiolo-gic method,we gathered and ana-lysed the 18 years'longitudinal dataof Chengzihe Coal Mine,Jixi. The result showed that it isavailable to use the 20 years dura-tion as a observation duration in stu-dying the relationship between theincidence of anthracosilicosis andthe dust exposure concentration.When we continued observing till the26th year,it showed that at mostonly 0.6 percent degree I anthraco.silicosis occurred. It proved that the concentra-tion of dust exposure to coal con-tained 10-20 percent free SiO_2 andcountry rock mixed dust is 9.5mg/m~3 averagely,if one exposed to suchcoal dust for 18 years,anthracosi-licosis might not occur to him. we suggested that it is suitableto revise the hygiene standard ofcoal dust which contains 10-20 per-cent SiO_2 as 8-9 mg/m~3.

为修订粉尘卫生标准提供依据,用流行病学方法对鸡西城子河煤矿18年动态观察资料整理分析,结果表明,在研究探讨煤矽肺发生与接触浓度的动态观察可以20年作为观察期限;持续观察至26年最多只有0.6‰Ⅰ期煤矽肺发生。并证明,接触含游离si0_21O~20%的煤、围岩混合性粉尘浓度平均为9.5mg/m~3,持续18年可不出现煤矽肺,建议含游离siO_210~20%的煤尘卫生标准修订为8~9mg/m~3为宜。

Serum total hydroxyproline (STHP), serum monoamine oxidase (SMAO), free proline in the liver and hepatic collagen (HC) were determined in CCl 4--induced cirrhotic rats and during the regeneration of the liver remnant after pairtal hepatectomy. The results show that (1) the consecutive determinations of the STHP and the SMAO might help to understand the metabolic changes of collagen in cirrhotic animals and, (2) the progress of degration of hepatic collagen in the hepatectomized group might proceed more rapidly...

Serum total hydroxyproline (STHP), serum monoamine oxidase (SMAO), free proline in the liver and hepatic collagen (HC) were determined in CCl 4--induced cirrhotic rats and during the regeneration of the liver remnant after pairtal hepatectomy. The results show that (1) the consecutive determinations of the STHP and the SMAO might help to understand the metabolic changes of collagen in cirrhotic animals and, (2) the progress of degration of hepatic collagen in the hepatectomized group might proceed more rapidly than that in the control group.

本实验测定了大鼠四氯化碳(CCl_4)性肝硬变及肝部分切除后余肝再生期间血清总羟脯氨酸(STHP)含量,血清单胺氧化酶(SMAO)活性,肝脏游离脯氨酸(HFP)浓度和肝脏胶原(HC)含量。实验结果表明SMAO活性和STHP浓度的动态变化,可反映肝胶原合成和分解代谢情况,并证明肝叶切除组动物,肝脏胶原的消退比假手术组更迅速。
