title: [Cyclic nucleotides of human and animal glial tumors].
abstract: Studies on the level of cyclic nucleotides (cAMP and cGMP) in human and animal glial tumours showed that the content of both nucleotides, especially that of cAMP, decreases in all the tumours. The cAMP/cGMP ratio also drops down. Concurrently it appears to be the most consistent parameter of nucleotide metabolism both in brain tissue and in human or animal glial tumours. The growing tumour affects cAMP and cGMP metabolism not only in the involved but also in the other hemisphere. No principal differences between human and animal tumours have been revealed in the content of cyclic nucleotides and its variation in tumour tissue.
