In rats, data on influence of i. v. administration of calcium chloride on the level of [Ca2+] in the blood and on process of oppression ofthermoregulatory and respiratory functions in rats in hypothermia. 0.18 or 0.135 mmol Ca2+ on the 3rd minute from beginning of the administration increased [Ca2+] in the blood from 1.01 +/- 0.03 to 2.56 +/- 0.08 mM (or 2.27 +/- 0.06 mM). Then [Ca2+] was reduced gradually, in 20 minutes from administration, solution of CaCh [Ca2+] exceeded the initial level by 20-30 %. The increase of concentration of ionized calcium in the rat blood strengthened the cold oppression of breathing and cold shivering as compared with the control (administration of physiological solution). Arrest of breathing in rats after administration of CaCl2 solution occurred at higher rectal temperatures (21 +/- 0.03 degrees C) as compared with control experiments (18 +/- 0.4 degrees C), p < 0.05. It is suggested that increase of [Ca2+] in the blood strengthens effects of cold in the form of oppression of thermoregulatory and respiratory functions.
