[Reaction of the animal adrenal cortex to the action of a strong, constant magnetic field and to a hypomagnetic environment].
Experiments were conducted on male albino rats; a study was made of the functional condition of the adrenal cortex following a single 30-minute (decapitation of the animals in 1, 8, 16, and 24 hours, and in 4, 8, 16, and 30 days) and repeated (for 30 minutes every day) prolonged (for 1 month) action of CMF (decapitation in 2, 4, 8, 16, and 30 days) and hypomagnetic field (for 8 and 30 days). Changes in the lipid content and in the alkaline phosphatase activity served as a morpho-histochemical criterion. A single brief CMF action proved to stimulate the adrenal function the first hours of the after-action; later the changes were oscillating in character. Prolonged repeated action of CMF depressed the functional activity of the adrenal cortex. Both in the first and in the second cases functional activity of the organism was almost completely restored by the end of the month, after the cessation of the CMF action. An 8-day stay of the animals in the hypomagnetic medium led to activation of the adrenal gland function, and a 30-day stay--to its reduction.
