[The regulation of XXXX synthesis].

@entity916 @entity2178 @entity1372 @entity1169
Secretion and synthesis of @entity916 are stimulated by the lack of @entity2178 and by a low @entity1372 intake. They are inhibited by a high @entity1372 intake, by denervation and by @entity1169 . A high @entity1372 intake can overcome the effect of the lack of @entity2178 . A low @entity1372 balance and the lack of @entity2178 did not have additive effects. The @entity1372 effects did not appear to depend on the presence of the macula densa, the presence of @entity2178 , or the presence of the nerve supply. It was not evaluated whether baroreceptors may be important in allowing @entity1372 effects to be processed, but in the experiments conducted there were no significant changes in blood pressure associated with alterations in @entity1372 balance. @entity1372 balance has an important effect on synthesis and secretion. This effect does not appear to be mediated by the usual set of controls and raises questions as to the signal relating @entity1372 balance to @entity916 synthesis. Secretion does appear to depend on macula densa. The role of the macula densa appears to control the basal level of @entity916 secretion and to permit the conversion and processing of prorenin to @entity916 .
