The Effects Of Osmotic Stress On Sodium, Potassium, And Chloride Metabolism In The Mongolian Gerbil, Meriones Unguiculatus, Mark William Hagood

Master's Theses

The effects of osmotic stress on sodium, potassium, and chloride metabolism and the physiological mechanisms governing these ions were studied in the Mongolian gerbil, Meriones unguiculatus. Animals were subjected to dietary regimens ranging from sodium-free to high-sodium diets for sixty days. Results indicate the gerbils were not physiologically stressed by the imposed diets. Apparently the animals regulate ion metabolism via intrarenal mechanisms and pituitary antidiuretic hormone while behavior and adrenal cortical activity are insignificant.
