Guanylate cyclase activity was assayed in homogenates, in particulate and soluble fractions from retina, cerebellum, cerebral cortex and adrenal gland of adult C3H/HeJ mice with a dystrophic retinopathy. In comparison to control mice (DBA/1J), in C3H/HeJ strain a significant decrease in guanylate cyclase activity occurred in homogenates from retina, cerebellum and adrenal gland. In particular a significant decrease was found in particulate fraction of retina, in the soluble fraction of cerebral cortex and cerebellum and in both fractions of the adrenal gland. In contrast to the retina and cerebellum where guanylate cyclase activity in homogenates was found significantly decreased both in the male and female, in the cerebral cortex guanylate cyclase decreased in both sexes although in female this was more marked.
Polyamine content, ODC and SAMDC activities have been assayed in cerebellum and brain cortex of hyperthyroid rats during postnatal development. Daily thyroxine treatment induced ODC and SAMDC biosynthesis in early periods of postnatal life in both cerebellum and brain cortex. In addition, in comparison to controls an increase in spermidine and spermine content was shown to occur in hyperthyroid rats. A functional correlation between polyamine content and nucleic acids could explain a correlation between polyamine biosynthesis and morphofunctional maturative processes in the brain.
