cAMP levels in reactive tissues around dimethylpolysiloxane solid implants.

By the aid of radioimmunologic assay, the authors measured the cAMP content of the reactive capsules around solid dimethylpolysiloxane implants in mice at different times; they also measured the same substance in some human connective tissues (granulation tissue and normal dermis) and compared together all the values they obtained. Different concentrations of cAMP in different tissues seem to reflect correspondent histologic findings, since they vary according to them. These values also seem to indicate a close correspondence between the development of the process of wound healing and of the foreign-body reaction following the implantation of alloplastic materials. On the basis of these data, the authors suggest an experimental therapeutic trial to enhance peripheral cAMP synthesis in order to control the process of reactive capsule constitution.
