中华医学杂志(英文版) 1993年第6期106卷 457-457页

The present study was designed to examine the effect of higher concentration of anisodamine on α-adrenergic responses in isolated canine blood vessels. Up to 10-3 mol/L, anisodamine did not significantly affect the responses of saphenous vein to α2-adrenergic agonist UK-14, 304. In contrast, anisodamine (10-5, 10-4, 10-3 mol/L) caused the concentration-response curves of femoral artery to norepinephrine (pA2=4.81±0.11) to phenylephrine (pA2=4.86±0.20) shift markedly. However, the antagonism on the α1-adrenergic responses of canine femoral artery to norepinephrine and phenylephrine by higher concentrations of anisodamine produces dose ratios which yield a linear Schild regression with a slope less than unity, indicating an inequilibrium between agonist, antagonist, and receptors. The probable mechanisms involved are discussed.

在欧洲，制造商越来越多地在汽车金属板上使用可焊接底漆（例如汉高公司的Granocoat？）以提高防腐蚀性能。例如，几年来，梅赛德斯-奔驰公司一直在其生产的车辆上使用可焊接底漆。梅赛德斯-奔驰已经将欧洲汽车上的穿孔质保延长到30年，这是因为可焊接底漆的使用大大改善了大型零件的空腔和法兰内的防腐蚀性能。

欧洲心血管介入协会(EAPCI)专家组系统总结了血管内超声(IVUS)和光学相干断层成像(OCT)这两种血管内影像学检查临床应用指征的现有证据,提供了关于IVUS和OCT指导经皮冠状动脉介入治疗(PCI)的应用价值,并明确了最可能从腔内影像学指导的介入治疗中获得临床收益的患者或病变类型,同时详细论述了PCI前如何使用IVUS或OCT优化支架尺寸(支架长度和直径)和手术策略的选择。此外,专家推荐对支架失败(支架内再狭窄或支架内血栓形成)的患者应常规进行冠状动脉内影像学检查,并首选OCT。最后,重点论述了IVUS和OCT在指导PCI和评估支架失败两个方面的优势和局限性,并对未来需要深入研究的领域进行了展望。

KG Karlsruhe Germany

Background: Ginkgo biloba extract EGb 761® is widely used to treat various types of vertigo. Aims: An exploratory trial was conducted to evaluate the efficacy of EGb 761® in addition to vestibular exercises in central vestibular vertigo caused by vertebro-basilar ischaemia. Subjects and Methods: In this randomised, placebo-controlled, double-blind trial, 40 patients were enrolled in the vertigo clinic of a neurological university hospital and treated with daily doses of 240 mg EGb 761® or placebo for a period of 180 days. All patients regularly performed vestibular exercises in addition. Efficacy was assessed using: a visual analogue scale for the patients to rate the overall intensity of vertigo;a numeric scale for physician-rated change;a vertigo score based on intensity, duration, and frequency of vertigo;and electronystagmography. results: Until day 180, the mean patient-rated intensity of vertigo decreased by 46% during EGb 761® treatment and by 19% with placebo (p ® group compared to the placebo group. Nystagmus or other eye movement disorders were present only in small subgroups of patients without sufficient statistical power to detect differences between treatment groups. Conclusions: EGb 761® alleviated vertigo caused by ischaemic lesions in the brainstem or cerebellum in patients undergoing vestibular exercises.
