[Health status of the workers exposed to strong, constant magnetic fields]. / Ocena stanu zdrowia pracowników narazonych na dzialanie silnych, stalych pól magnetycznych.

Forty two workers underwent examinations under clinical conditions. The workers were affected by the magnetic field of intensities ranging between 112-190 Gauss, depending on the workplace. They underwent internal, ophthalmological, psychological, psychiatric and analytical examinations and the health status of those exposed was compared to that of twenty controls. Most subjects, mainly those of long length of employment in e-m fields exposure, exhibited nonspecific abdominal pains, general weakness, insomnia, increased thirst and conjunctivitis.

Pentapeptide infusion test.

Pentapeptide infused intravenously in graded doses provoked at a dose of 1.5 microg per kg per hour a peak HCl output, which was significantly higher than the HCl secretion induced by intravenous histamine in a dose of 40 microg per kg per hour in five healthy subjects. Pentapeptide infusion test at a dose of 1.5 microg per kg per hour appears to be a very reproducible and safe mode of gastric stimulation, giving a sustained and high level of gastric secretion in 20 subjects, including 10 healthy men and 10 duodenal ulcer patients. Infusion test with pentapeptide has some advantage over histamine stimulation in so far as it is safe, and almost completely free of side-effects. No difference in the response curves to pentapeptide and histamine was found between the normal subjects and duodenal ulcer patients.
