Fiziologicheskii Zhurnal Sssr Imeni I. M. Sechenova
An increase in the water permeability of the frog urinary bladder due to vasopressin, correlates with an increase of cAMP content in the bladder tissue. The osmotic permeability reached its maximum in 15-20 min. The sharp increase of inositol triphosphate content was observed within 20 sec after vasopressin administration, whereas cGMP content significantly decreased within 5 min. The augmentation of cAMP content seems to lead to a rise in water permeability white inositol triphosphate and cGMP acted, probably, as modulators of the vasopressin effect.
