Effect of occupational therapy on the psychosocial status of patients with myocardial infarction at the second stage of rehabilitation

Occupational therapy was added to the rehabilitation program at the second stage of rehabilitation in 42 myocardial infarction patients. Its psychosocial effect was assessed by psychological tests in comparison to a control group of patients, unexposed to occupational therapy.

The experimental treatment of cyanide poisoning with a methemoglobin solution]

The stroma-free methemoglobin solution proved to be an effective antidote against acute cyanide poisoning in experiment. The poisoning was induced by intraperitoneal administration to rats of cyanide solutions in doses of 5, 10 and 15 mg/kg. Methemoglobin solutions were injected intravenously in doses of 2 and 4 g/kg. All the rats given methemoglobin solution after the administration of cyanide survived. Spectrophotometry of rat urine demonstrated rapid excretion of methemoglobin cyanide.

Effect of dietary protein on Masheri-induced drug metabolising enzymes

The modulation of drug metabolising enzymes by Masheri extract (ME) and Benzo(a)Pyrene [B(a)P] was studied in male Sprague Dawley rats fed different dietary protein levels. Two groups of 21 days old male Sprague Dawley rats were put on a high protein diet (SHP) with 20% Casein, and a low protein diet (SLP) with 3% Casein semisynthetic based diets for 12 weeks. The SLP fed animals showed lower basal levels of the Phase I activating enzymes viz. Cytochrome P450, Benzo(a)Pyrene hydroxylase, Benzphetamine demethylase and Phase II glutathione detoxification system viz. Glutathione (GSH) and Glutathione-S-transferase. ME and B(a)P treatment significantly depleted the glutathione detoxification system in the SLP group whereas an opposite effect was observed in the SHP group. Interstingly, ME and B(a)P treated rats in the SLP group showed a higher percent increase in the hepatic and pulmonary Phase I enzyme activities than those observed in the treated ME/B(a)P treated SHP rats. Furthermore, both ME and B(a)P significantly decreased the hepatic pool of vitamin A while a concomittant increase in that of vitamin C was observed.     

Disorders of the hemodynamics and myocardial structure in patients with infectious-allergic myocarditis complicated by heart failure

A study of 30 patients with infectious-allergic myocarditis, accompanied with chronic heart failure made use of echocardiography, hemodynamic assessment by cardiac catheterization, endomyocardial biopsy. A relationship is demonstrated between hemodynamic changes and the lesion of cellular ultrastructural apparatus, mitochondria, in particular. Patients with first-stage heart failure associated with infectious-allergic myocarditis showed incomplete diastole, while systolic changes were found in patients with severe manifestation of circulatory insufficiency.
