Effect of different illumination conditions and ionic environment on the guanylate cyclase activity in retina, optic nerve and optic chiasm of the rat
{{output}}
Guanylate cyclase is sensitive to changes of light and dark periods in incubated extracts obtained from soluble fractions of the retina, optic nerve and optic chiasm. The changes in guanylate cyclase activity found, about 100-fold between dark and light period... ...
