Post-natal development of plasma and urine osmolality, as well as plasma renin activity, aldosterone and cortisol levels were studied in calves between 1 and 9 months of age. The ratio of urine to plasma osmolality rose from 0.8 at an early post-natal age to 3.8 at the end of the study period. Plasma renin activity, plasma aldosterone and cortisol levels did not show any change during the post-natal development period. The plasma concentrations of these hormones were in the same range as is found in the adult.
研究了1至9月龄犊牛血浆和尿液渗透压以及血浆肾素活性、醛固酮和皮质醇水平的产后发育情况。尿液与血浆渗透压之比从出生后早期的0.8升至研究期末的3.8。血浆肾素活性、血浆醛固酮和皮质醇水平在产后发育期间未显示任何变化。这些激素的血浆浓度与成年动物中的浓度范围相同。
