[Immunoglobulin E (IgE) in the blood and the diagnosis of hepatic echinococciasis].

The paper presents the results of a study of the significance of IgE in the diagnosis of echinococciasis. Preoperative examinations of patients with showed the increased serum concentrations of IgE. The decreased concentration of IgE was recorded on postoperative day 20.

[External respiratory function in echinococcosis].

The paper presents the results of a study of the parameters of external respiratory function in 33 patients with echinococcosis. Restrictive respiratory dysfunction was detected in 85.71% of the examinees.

[ECG dynamics at rest and during exertion after mitral commissurotomy].

Four degrees of left atrial electrical activity were identified by ECG made before and after closed mitral commissurotomy in 70 patients with mitral stenosis and sinus rhythm. The critical electrical activity of the left atrium and hypertrophy of the right ventricle along with the typical auscultation pattern of mitral stenosis were found to cardiographically correspond to critical stenosis of the left atrioventricular ostium in most cases. The area of the mitral orifice, which was attributable to that of the body, was 0.
