Popis:	The ultracytochemical localization of guanylate cyclases A and B activity has been studied after stimulation with atrial natriuretic peptide and C-type natriuretic peptide in light- and dark-adapted retinas and pigmented epithelium. The results showed that both peptides stimulated guanylate cyclases A and B activity in light-adapted retinas only. Guanylate cyclases A and B activity was detected on plasma membrane of body of photoreceptors, bipolar, horizontal and ganglion cells, on plasma membranes of interneuronal connections at plexiform layers and on the plasma membrane of fibres at the nerve fibres layer. Independently of the light-or dark-adapted state, the pigmented epithelium also presented guanylate cyclases A and B activity on basal and lateral plasma membranes.
