title: [Age dependence of adenylate cyclase activity and cAMP generation in aortas and femoral arteries of rats (author's transl)].
abstract: It is well-known that the cAMP-adenylate cyclase system is important in mediating the effects of numerous hormones. We investigated the age-dependent behaviour of this system in aortas and femoral arteries of male Wistar rats (at the age of 10 days, 1, 4, 8, 12, and 22 months).
  
  
  RESULTS
  1. The basic adenylate cyclase activity had considerably been decreased beyond the first month of life, thereafter it was almost constant. 2. The response of adenylate cyclase to guanylyl-imidodiphosphate and NaF had essentially been elevated since the 4th month of age. 3. The possibility of stimulating the cAMP generation due to epinephrine and histamine had substantially been increased since the 12th month of age.
