[Changes in the electrolyte composition of the heart, liver and kidneys of the rat in pre- and postnatal ontogeny].

From the 19th day of embryonic period, within 4 days, i. e. up to the beginning of postnatal life, the weight of the heart in rats increases by 3.

[Effect of weightlessness and an artificial gravitational force on the ion-regulating function of the kidney in rats].

Weightless rats showed greater changes in the fluidelectrolyte metabolism and ion regulatory function of the kidneys than centrifuged rats. During water loads they exhibited an increased sodium excretion. During potassium loads they displayed a higher potassium excretion.

[Water-salt metabolism in white rats following a flight on the Cosmos-690 biosatellite].

As a result of a combined effect of prolonged weightlessness and ionizing radiation at a dose of 800 rad aboard the biosatellite Cosmos-690, the recovery time of certain parameters of fluid-electrolyte metabolism (hydration of the body, balance of sodium, potassium, calcium) was longer than that for the animals which flew abroad the biosatellite Cosmos-605.
