title: [The effect of the addition of Co2+ ions on the osmolarity and concentration of Na+, K+ and Ca2+ ions in the blood serum of rats].
abstract: The addition of cobalt chloride to the female rat blood serum resulted in a decrease of serum osmolality and in an increase of ionized calcium concentration probably due to ousting of calcium out of proteins and alteration of proteins characteristics. The osmolality of saline and activities of sodium, potassium and calcium in it did not change following addition of Co2+. The administration of vasopressin and dehydration were not followed by alteration of characteristics of serum reaction in response to addition of Co2+ in rats. More obvious effect of Co2+ was revealed with high initial serum osmolality.
