ABSTRACT
Objective To observe the effect of diabetes on the activation of kinin-system and the role of the system in development of diabetic nephropathy. Methods The TKA activation was measured and the function of kinin-system was changed by the antagonist of bradykinin B2 receptor-HOE 140 and kallikrein. Results The activation of TKA decreased sharply at 18 week in diabetic acts and was much lower than the levels of TKA at & week or in control rats (P
ABSTRACT
Patients with thyrotoxicosis had a normal circadian rhythm of ACTH and F,but the level of serum F was lower than controls due to excessive degradation.The responsiveness of ACTH to dexamet-hasone suppression or insulin hypoglycemic stimulation was normal.Whereas the circadian secretion of ACTH and F was also normal in patients with primary hypothyroidism,and the concentration of F was inreased with normal ACTH level.There were stunted responses of ACTH to suppressing and stimulating tests,which were thought to be due to the fact that the corticotropes were impaired by hypertrophy or hyperplasia of thyrotropes in primary hypothyroidism.
