国际心血管病杂志 1986年第3期 152-153页

作者： alderman J Grossman W 范伟

特发性扩张型心肌病的传统疗法是使用利尿剂、正性肌力药物和血管扩张剂。尽管血管扩张剂和正性肌力药物有新的发展,但其预后并无改善。1975年瑞典 Waagstein等报道,应用一种与传统疗法不同的β-阻滞剂治疗扩张型心肌病取得了显著而持... 详细信息

Patients with scalp psoriasis suffered from a lower quality of life relating to the highly visible site of their psoriatic lesions. In consequence this fact stimulates investigations involving treatments of this dermatologic disease. The aim of this review is to evaluate the topical treatments for scalp psoriasis compared with placebos. Methods: A systematic review was performed using searches in the database LILACS, MEDLINE, Cochrane Library, and Embase. As selection criteria were chosen eligible publications involving randomized controlled trials, patients with scalp psoriasis diagnosed clinically or by biopsy, interventions with topical treatments for scalp psoriasis compared with placebo. Outcome related to the reduction in severity of psoriasis of the scalp, assessed by physicians and patients, and assessment of adverse effects that required discontinuation of treatment. The results have shown that the patients were aged 12 to 97 years, including 3441 patients. Ten of the fifteen studies included reported gender data. Patients were mostly female. Twelve studies were about psoriasis’s severity. These studies in which the severity has been described, the classification of severity was mild (0 study), mild to moderate (1 study), moderate to severe (11 studies) and severe (0 study). In conclusion, topical corticosteroids, calcipotriol, ciclopirox olamine and associations between them are effective in the treatment of scalp psoriasis. Clobetasol propionate (0.05%) was the most effective active ingredient in several vehicles in the induction treatment of scalp psoriasis.

1991～1993年俄勒冈中部草地早熟禾种子产区麦角病的发病率分别为36％,46％和62％,有个别地区(2％～13％)发病极严重(每克种子有20多个菌核)。其严重度(菌核重量百分数)分别为0.85％,0.07％和0.34％。因麦角病更换种子的损失估计为0.22％,0.02％和0.08％。为减少麦角病污染达到标准纯度种子而采用清种技术导致上市种子量减少7.8％。1991～1993年估计因更换种子损失分别达75625,4758和17076美元。清种损失分别为37669,8171和21946美元。草地早熟禾收获季节有利于麦角病发生的杂草有雀麦属、黑麦属、羊茅属、早熟禾属的一些种。然而,俄勒冈中部杂草穗部很少被浸染,杂草似乎对麦角病的发生无多大作用。大多数受害田(处理前每克种子有1个以上的菌核)或感染麦角病的杂草分布于研究地的南缘。

肖特基二极管技术为常温下毫米波信号的检测提供了有效的解决方案。它具有极低的寄生电容和级联电阻,可用于该频段的倍频器、混频器和检波器当中。相比于Galey Cell和热辐射测定器(Bolometer),基于肖特基二极管的直接检波技术具有低噪声、高反应率和常温使用的特点。本文介绍了一种基于波导结构的零偏置肖特基二极管检波器,采用E面探针传输波导基模电磁波,通过阻抗匹配实现微带线到二极管的耦合。测试结果表明,在-30 d Bm输入功率下:电压反应率的峰值可达8 900 V/W;在75 GHz^105 GHz的频率范围内,电压反应率在1 000 V/W以上。
