抗人甲状腺过氧化物酶抗体与其他自身抗体的关系

甲状腺过氧化物酶（ＴＰＯ）是甲状腺微粒体的抗原成分。在纯化抗原建立测定抗ＴＰＯ抗体ＥＬＩＳＡ法的基础上，并对抗ＴＰＯ与其他自身抗体的伴随关系作了研究。发现除自身免疫性甲状腺病有较高阳性率外，ＳＬＥ等患者抗ＴＰＯ检出率也很高（１０％￣５２．１％），且抗ＴＰＯ阳性者，抗核抗体等其他自身抗体的阳性率也高达３０．８％￣９５．２％。抗ＴＰＯ抗体与其他自身抗体的相关系数ｒ＝０．７４６７（Ｐ〈０．０１）。     

急性心肌梗塞溶栓治疗后D-二聚体动态变化的意义

在22例符合溶栓条件的急性心肌梗塞患者，应用尿激酶溶栓治疗前后，用乳胶颗粒凝集法检测了血清D-二聚体的动态变化和对照组比较，D-二聚体含量在梗塞相关动脉（IRA）再通者明显升高（P＜0．01），而IRA未再通者仅稍有升高（P＞0．05）。结果表明，D-二聚体水平和IRA再通与否之间有良好的相关性，且方法简便，易于推广。     

雷公藤多甙影响蟾蜍神经—肌接头传递初探

用微电极细胞内记录终板电位（ＥＰＰ）的电生理学方法，在２０只成年蟾蜍的坐骨神经缝匠肌标本上研究了雷公藤多甙（ＴＷＰ）以神经肌接头（ＮＭＪ）兴奋传递的影响。结果表明：ＴＷＰ可引起ＥＰＰ振幅改变，物兴奋传递，而且其影响具有明显的量效依赖关系，适当浓度的ＴＷＰ能明显地增加ＥＰＰ振幅，促进ＮＭＪ的兴奋传递。     

头孢克洛在健康人体内的药物动力学研究

采用ＨＰＬＣ测定健康志愿者血浆中头孢克洛的浓度。方法简便快速，结果准确。平均回收率为１０２．１８±４．０１％，日间及日内ＲＳＤ均小于６％。血药浓度－时间曲线符合一室模型。     

温阳健心灵口服液治疗充血性心力衰竭的临床与实验研究

以煎剂形成筛选治疗CHF的处方，发现温阳益气方改善泵血功能的效果优于单纯益气和养阴益气的处方。根据前方制备的温阳健心灵口服液保持了原煎剂的疗效，并被毒理学试验证明毒性极低。动物药效学及临床试验发现该药不仅能改善心衰犬和病人的左室收缩功能，还能改善其舒张功能。除此，它还具有利尿作用和使PAWA、SVR和PVR下降的作用，这也是它抗心衰的机理之一。90例的临床观察（疗程2周）表明该药总有效率、近期治愈率和显效率分别达88．9％、7．4％和18．5％，其效与开搏通组无明显差异。     

Effects of Oren-gedoku-to and Unsei-in,Chinese Traditional Medicines,on Interleukin-8 and Superoxide Dismutase in Rats

This study was conducted to elucidate the mechanisms of action of two Chinese traditional drugs, Oren-gedoku-to and Unsei-in, which have been used for many years in the treatment of inflammatory disorders. In rats with acetic acid-induced inflammation, both drugs reduced interleukin-8 concentrations in the serum. Neither drug significantly affected superoxide dismutase activity in the serum, although Unsei-in increased superoxide dismutase activity in liver after 1 month of administration. Oren-gedoku-to showed no significant effect on liver superoxide dismutase activity. It was considered that these medicines exert their anti-inflammatory effects mainly on the early stages of inflammation, wherein increased capillary permeability and migration of leucocytes occur.     

肾移植术后受者环孢素的血药浓度监测

目的 观察环孢素血药浓度与肾移植效果间关系。方法 对９７例接受同种异体肾脏移植术受者术后８周内２０６例次环孢素血药浓度监测结果进行回顾性分析，按照受者术后的临床表现、生化指标将其分为术后正常组、急性排斥组、急性毒性组，采用荧光偏振免疫测定法，以单克隆抗体试剂测定环孢素血药浓度。结果 术后正常组６２例移植肾功能良好，环孢素的给药剂量为５２±１．９ ｍｇ／ｋｇ·ｄ，１７１例次环孢素血药浓度的平均值为３０９．８５±１３１．６９μｇ／Ｌ；术后急性排斥组 ２６例，距发生排斥反应最近一次的环孢素血药浓度平均为１６５．８０±１２３．１３μｇ／Ｌ，环孢素的给药剂量为 ４．８±１．６ｍｇ／ｋｇ·ｄ；术后急性毒性组９例，距发生毒性反应最近一次的环孢素血药浓度平均为５５６．５１±１０２．５０μｇ／Ｌ，环孢素的给药剂量为６．２±１．０ｍｇ／ｋｇ·ｄ。三组之间环孢素的给药剂量无显著性差异（Ｐ＞０．０５），但环孢素血药浓度却相差很大，两两之间有显著性差异（正常组与排斥组 Ｐ＜ ０．０５；正常组与毒性组Ｐ＜ ０．０５；排斥组与毒性组Ｐ＜ ０．０１）。结论 环孢素浓度较低时，出现排斥反应的可能性较大；而环孢素浓度较高时，发生毒性反应的机会较多。     

Mediastinal lymphadenopathy: a variant of incomplete Kawasaki disease

A 14-month-old girl presented with a 4-d history of fever and generalized exanthema. Four characteristic symptoms of incomplete Kawasaki disease (KD) were present on admission (fever, rash, non-purulent conjunctival injection, oropharyngeal changes) and then followed by oedema of the hands and feet and mild plantar desquamation. The typical laboratory features of KD, such as elevated erythrocyte sedimentation rate, leukocytosis, thrombocytosis, and positive C-reactive protein were also seen. Ultrasound examination of the mediastinum revealed the presence of a lymph node, 30 mm in diameter, below the tracheal carina. Thoracic CT scan confirmed the mediastinal lymph node. The patient was treated with aspirin and intravenous γ -globulin. Ultrasound study of the mediastinum, which was carried out 6 weeks after hospital discharge, showed that the lymph node had disappeared. This case illustrates that lymph nodes other than cervical lymphadenopathy should be sought when the diagnosis of classical or atypical KD is suspected.
