Bacteriostatic and biological stimulation effect of Mepitel on experimental burns on the skin of rats.

This study was conducted on 200 white Wistar rats weighing about 200 g each. The animals were divided into two equal groups--an experimental one, with Mepitel (SCA Mölnlycke) dressings, and a control group with cotton gauze dressings. Microbiological and histological examinations and measurements of the wounds made on the 3rd, 7th, 14th, 21st and 28th days after the 3rd-degree heat burn was inflicted using the standard method.

[Significance of left ventricular structural changes in arterial hypertension for the prolongation of electric cardiac systole].

Echocardiography was used to examine 93 patients with Stages I and II arterial hypertension with a view to clarifying the impact of structural changes occurring in the left ventricle in the course of the disease on the duration of electric systole. Left ventricular muscle mass was found to become larger with an increase in corrected Q-T interval duration, the upper dependence correlating better with concentric hypertrophy. The duration of electric systole increased with deteriorated left ventricular function.
