Popis: 1. 1. In adipose slices of the guinea pig (Cavia porcellus), adrenocorticotrophic hormone (ACTH) produced a significantly higher lipolytic response (increased V max and decreased K m ) as compared to norepinephrine (NE), thus indicating a marked difference with human adipose tissue. 2. 2. Exercise-training caused a significant increase in the affinity of the lipolytic response in adipose tissue towards both ACTH and NE, but had no significant effect on V max . 3. 3. Prolonged in vivo treatment with both ACTH and NE significantly decreased the responsiveness (affinity and capacity) of adipose slices towards ACTH. Responsiveness towards NE was much less affected.
