Nocturnal, daytime, and postural changes of plasma XXXX before and during @entity619 in adenomatous and @entity1368 .

@entity1 @entity1369 @entity619 @entity701 @entity916 @entity1368
The relative importance of ACTH and the @entity916 angiotensin system for control of @entity1369 was studied in eight @entity1 with adenomatous primary (APA) and four with @entity1368 ( @entity1368 ). Plasma @entity1369 (PA) and @entity701 (PC) were measured in blood collected during the night at 15-min intervals between 0500--0800 h by integrated sampling on day 1 and in casual samples during the daytime while @entity1 were in the upright and in the supine position (days 1 and 2, at 1200, 1600, and 2000 h). PRA was measured in all daytime samples. On days 3, 4, and 5, 2 mg @entity619 were given, and the same protocol for blood sampling was repeated on days 4 and 5. During the night, mean PA in @entity1368 @entity1 was markedly lower than that in APA @entity1 . PA @entity1 correlated with PC in both groups. @entity619 reduced the mean nocturnal PA in both groups to equal proportions. In the daytime, the mean recumbent PA in @entity1368 @entity1 was also significantly lower than that in APA @entity1 but was equal in both groups while subjects were in the upright posture. Daytime PA significantly correlated with PC in APA @entity1 and with PRA in @entity1368 @entity1 . During upright posture, @entity619 did not reduce daytime PA in either group. In the supine position, @entity619 reduced daytime PA values in APA but not in @entity1368 @entity1 . Thus, short time fluctuations of PA during the night are equally influenced by ACTH in APA and @entity1368 @entity1 , though at markedly different levels of @entity1369 production. During the daytime, the influence of ACTH on PA remains apparent in the group with APA. However, the @entity916 -angiotensin system seems to play a predominant role in the control of PA during the daytime in @entity1 with @entity1368 . During @entity619 and ACTH suppression, PA in APA @entity1 rises in response to upright posture as it does in @entity1368 @entity1 .
