[Control of the regeneration of small pieces of the planarian Dugesia tigrina by cylic AMP and GMP nucleotides].
The effects on regeneration of cyclic nucleotides AMP and GMP were studied on small pieces of the planarian worm Dugesia tigrina. db cAMP, 8Br cGMP and substances acting on their metabolism were used in this work (aminophylline, insulin, imidazole). It seems that these second messengers play a role in a mechanism of regulation in which cGMP has a promotive action and cAMP an inhibitive one.
