[Use of ofloxacin in the treatment of infections of the lower respiratory tract].

The taxonomy of the causative agents of lower respiratory tract infections (LRTI) isolated from patients in the Moscow Region was studied and the clinico-microbiological efficacy and tolerance of ofloxacin used in their treatment were estimated. The microbiological tests of the sputum specimens from 168 patients with LRTIs most frequently detected gram positive cocci with the predominance of Streptococcus spp. (65.

[Myocardium in chronic obstructive lung diseases].

The analysis of endomyocardial biopsies (10 specimens) and clinical observations suggests the conclusion: myocardial lesions in OPD patients with pulmonary hypertension are due to metabolic and hemodynamic disturbances. In addition to myocardial hypertrophy, myocardial dystrophy contributes to development of cor pulmonale.

[Radiocardiography and rheography of the pulmonary artery in the diagnosis of disorders of hemodynamics and right-ventricular contractility in patients with chronic obstructive bronchitis].

Radiocardiography and rheography of the pulmonary artery were used to examine impairments in hemodynamics and contractile function of the right ventricle in 40 patients with chronic obstructive bronchitis complicated with persistent hypertension. Right ventricular hemodynamic and contractile impairments were shown to be not equivalent with similar clinical and functional signs of pulmonary hypertension. This fact indicates that the use of special techniques is of practical value in the determination of right ventricular hemodynamics and myocardial contractility in patients with chronic obstructive bronchitis.
