Abstract：
:Circulating norepinephrine and epinephrine were determined nine times over a 1-hour period in chronically instrumented ewes (n = 4), their fetuses (n = 4), and lambs (n = 4). In an apparent resting state, assessed by subjective and biophysical parameters, marked fluctuations were demonstrated in the mean norepinephrine and epinephrine values between animals and in the range of the concentrations of each individual animal. The significance of the fluctuations in resting plasma norepinephrine and epinephrine concentrations is discussed.
