The prolonged-action form of Lomir (isradipine) in the treatment of mild and moderate essential hypertension

24-hour monitoring of arterial pressure has been performed outpatiently in 20 subjects with mild or moderate essential hypertension using portable system Space Labs 90207. The design of the study implied 2 weeks of observation without any treatment followed by a 4-week course of lomir SRO-5 plus a 2-week course of lomir administration in a double dose. Control examination was performed at the end of each period. It was established that a 4-week lomir course results in a lowering of systolic and diastolic pressure by 8.4 + -2.1 and 6.9 + -1.3 mm Hg, respectively. Double-dose lomir was also effective: a fall in both systolic and diastolic pressure by 15.6 + -3.2 and 8.1 + -1.8 mm Hg, respectively, was achieved.     

Yeasts contaminating salmon roe

Quantitative and species compositions of yeast contaminating eggs, fry and fingerlings of Salmo gairdneri Rich under artificial breeding have been studied. Prevalence of species of genera Candida, Rhodotorula, Cryptococcus and Debaryomyces is noted. Yeast isolated from perished eggs and sick fry do not possess pathogenic properties. Certain strains of yeast make stimulating effect on the studied microorganisms.     

In-situ monitoring of fibre and matrix deformation in fibre/polymer composites

Three methods, namely microphotoelasticimetry, Raman spectroscopy and surface microgrids, are currently used at ONERA on fibre-reinforced polymers to measure the in-situ fibre or matrix deformation. They provide the materials scientist with valuable indications on the early damage growth. Recent results are given and information about the limitations of the methods are indicated.     

Results of peripheral iridectomy in narrow-angle glaucoma and of prophylactic iridectomy (author's transl)

During a period of three years 79 eyes with narrow-angle glucoma were operated on, and prophylactic iridectomy was performed in 55 eyes. In this way, narrow-angle glaucoma in the fellow eye, which frequently occurs, was prevented. There are less postoperative complications with therapeutic and prophylactic peripheral iridectomy than with filtering operations. In view of the pathogenesis of narrow-angle glaucoma peripheral iridectomy is the most economical and effective procedure for preventing another attack and narrow-angle glaucoma in the fellow eye.

驱动LED串的DCM升压转换器简化分析(1)——理论分析

固定频率升压转换器采用不连续导电模式(DCM)工作,能够有效地用于快速调光操作,提供比采用连续导电模式(CCM工作的竞争器件更优异的瞬态响应,这种转换器非常适合于以恒流模式驱动LED串。但驱动LED的升压转换器的交流分析,与使用标准电阻型负载的升压转换器的交流分析不同,在推导最终的传递函数时必须非常审慎。本文分为两个单元:⑴理论分析,介绍如何推导驱动LED串的升压转换器的小信号响应;⑵实际考虑,深入研究实施方案,并验证经验结果及与理论推导比较。     

New approaches to the therapy of rheumatoid arthritis

Design of highly selective biological substances made use of three basic components of a complex pathogenetic model of RA: the presence of antigen-presenting cells, genetic defects and autoimmune aggression. Efforts now are directed to development of monoclonal antibodies (MAB) to receptors of T-cells, B lymphocytes, MAB to CD 18 and CD54, cytokines, search for natural inhibitors of cytokines, introduction of cytokines. Many of such preparations including recombinant interferons proved clinically promising.
