    Abstract:
    The female rats were flown on Cosmos-1514 for 5 days during gestation days 13 through 18. The rats showed a significant reduction of the Ca concentration in the liver and kidneys, its smaller decrease in the skin, and no changes in bones. The fetus weight decreased, its water content increased, and the content of Na, K, Ca and Mg remained unchanged. The 15- and 30-day pups of the flown rats did not exhibit any differences in the water and electrolyte content in bones, skin, liver or kidneys as compared to the controls. These data indicate that water and electrolyte homeostasis of growing fetuses was highly stable and the deviations that emerged under the influence of space flight factors on the mother-fetus system rapidly returned to the norm.
