[Visual efficiency of pilot using of the night vision glasses].

Questionnaires filled out by 24 helicopter pilots using the night vision glasses (NVG) showed that minimization of the risk of visual discomfort was, first of all achieved through proper adjustment of image brightness and setting NVG time limits. The experiments enabled determination of the most favorable range of brightness (0.67-1.

[Comparative study of retard and non-retard forms of isosorbide-5-mononitrate in coronary patients with stable angina pectoris].

An open cross-over trial compared retard and non-retard forms of isosorbide-5-mononitrate (monomac 50D and isomonat, respectively) in 15 patients with stable angina of effort (functional class II-III). Both drugs were found rather effective, they significantly increase exercise tolerance. A single daily dose of monomac 50D reduced the number of anginal attacks.

[Comparison of dinitrate isosorbide retard forms in ischemic heart disease patients with stable effort angina].

Aim: To compare antianginal and anti-ischemic efficiency and tolerance of two forms of isosorbide dinitrate--cardiket-retard 120 mg and cardiket-retard 40 mg in IHD patients with stable effort angina.

Material And Methods: The study included 18 IHD patients with stable angina of functional class II (5 patients) and III (13 patients). The trial was open cross-over.
