The authors analyse the efficacy of extracorporeal heparin precipitation of plasma proteins (selective plasmapheresis) in patients with immune complex pathology. The method lies in extracorporeal precipitation at +4 degrees C of fibronectin, cryofibrinogen and other macromolecular complexes with the aid of heparin, followed by plasma return to the patient. The method was applied to 39 patients. ⋯ Application of the method to the treatment of rheumatoid arthritis permits reducing the dose of steroid hormones, thereby not stimulating the disease activity. The method is the therapy of choice in different diseases associated with polyvalent allergy. In amyloidosis and multiple sclerosis, the method efficacy is questionable.(ABSTRACT TRUNCATED AT 250 WORDS)

The role of ketoacidotic conditions in the occurrence of diabetic angiopathies and influence of the latter on the occurrence and development of ketoacidosis in patients with diabetic vascular lesions was studied. Altogether 1152 diabetes mellitus patients were examined. ⋯ Diabetic nephropathy was shown to cause the development of ketoacidotic conditions as was demonstrated by a higher frequency of ketoacidosis in persons with diabetic nephropathies. The period of disease made a decisive effect on the gravity and progression of vascular lesion in diabetes mellitus.

Daily monitoring of the ECG, catheterization of the pulmonary artery, tetrapolar chest rheography, occlusion plethysmography and polarography were employed to study the antiarrhythmic efficacy and the effects on the central and peripheral circulation of the new antiarrhythmic etmozine and etacyzine. Twenty-two patients with a frequent chronic ventricular premature heart beat (PHB) and clinically marked circulatory failure (CF) were entered into the study. Intake of etmozine (600 to 800 mg daily) and etacyzine (100 to 300 mg daily) over 5 to 6 days exerted a positive antiarrhythmic effect in 52.6 and 83.3% of the patients, respectively. ⋯ The treatment with both etmozine and etacyzine given in courses promotes the improvement of the microcirculation and tissue oxygen metabolism in patients presenting with CF. More pronounced positive shifts in the microcirculation were achieved with etacyzine. Apparently, this bears on a more demonstrable arteriolodilatation effect of the drug.(ABSTRACT TRUNCATED AT 250 WORDS)

Comparative Study
[Autonomic, cardio- and hemodynamic indices of healthy men, representatives of the native and nonnative population of Kazakhstan].
Healthy men, representatives of the indigenous population and newcomers, have some differences on the part of the vegetative and cardiovascular system. The newcomers mostly show coronary atherosclerosis and predominance of the tone of the ergotropic system. The cardio- and hemodynamic differences manifest by more pronounced shifts on making orthostatic and exercise tests, by an appreciable rise of myocardial contractility and energy expenditure for blood translocation.

A study was made of the effect of selective plasmapheresis (SPP) on the concentration of circulating immune complexes (CIC). The method is based on precipitation at 4 degrees C of plasma fibronectin and associated macromolecular complexes by means of heparin. Sterile plasma of the patient is separated from the precipitate, frozen and kept at -20 degrees C till the next plasmapheresis during which it is returned to the patient instead of the donor's one. ⋯ It was established that after the first session of SPP the CIC content sharply declined followed by a gradual increment and exceeded the initial values toward the beginning of the second session. After the second SPP the patients manifested the same tendencies. The CIC content reached a maximum by the third SPP and then fell from session to session.(ABSTRACT TRUNCATED AT 250 WORDS)
