[The membranogenous action of occupational hazards from the manufacture of black copper on older individuals].

Many-year investigations of health status, aging process and occupational diseases in rough copper production workers, including elderly individuals, revealed the occupational factors (sulphur dioxide, industrial dust, etc.) harmful for membranes. Lowered share of phospholipids containing polyunsaturated fatty acids, that changes the physical and chemical properties of membranes and cellular receptors and enzymes, was found harmful for membranes. The most severe changes were seen in the workers exposed to sulphur dioxide.

[Central hemodynamics and phase structure of the left ventricular systole during peritoneal dialysis in poisoning with organophosphate insecticides].

Central hemodynamics and myocardial contractility have been studied during intermittent peritoneal dialysis (PD) in 46 patients with severe poisoning with organophosphorus insecticides (OPI). The volume of liquid, administered into the abdominal cavity for 30-40 min, was 1.5-2 1. During PD no considerable disturbances in the parameters under study have been observed irrespective of the baseline blood pressure level. That is why PD is recommended in patients with most severe forms of OPI poisonings accompanied by marked disturbances in hemo- and cardiodynamics.

[Pathogenesis of intra-operative disruption of hemodynamics during hemodialysis of patients poisoned by phosphorganic insecticides, complicated by the development of exotoxic shock].

The results of central hemodynamic and myocardial contractility studies during hemodialysis in 62 patients with severe fluoroorganic insecticide poisoning complicated by exotoxic shock are reviewed. It has been established that hemodynamic disturbances are manifested in progressing fall of venous pressure, stroke volume and cardiac output accompanied by the onset of phase myocardial hypodynamia syndrome. The leading role of hypovolemia resulting from ultrafiltration in the pathogenesis of the above hemodynamic disturbances has been revealed. The results obtained make it possible to outline approaches aimed at correction of intraoperative hemodynamic disturbances and to increase safety of extracorporeal hemodialysis.
