Long-term effects of polyacrylamide hydrogel on human breast tissue.

Polyacrylamide hydrogel is an atoxic, stable, nonresorbable sterile watery gel consisting of approximately 2.5% cross-linked polyacrylamide and nonpyrogenic water. Polyacrylamide hydrogel is widely used in ophthalmic operations, drug treatment, food packaging products, and water purification.

[Immunologic monitoring in transplantation of hydrophilic polyacrylamide gel].

There was no significant difference in the level of basic immunological indices between those female patients having received a breast prothesis with making use of the polyacrilamide gel (PAAG) interfall and controls, subjects who had not received a breast prothesis, and group of patients in whom the gel was administered by injection, which fact corraborates the conclusion about immunological tolerance of the gel, with no dependence on the way in which it is used being noted.

[State of cellular and humoral immunity after soft tissue endoprosthesis implantation and correction of body forms using biogel Interfall].

Injection implantation of polyacrylamide gel "Interfall" in soft tissues was conducted in 110 patients in 1992-1997 yrs. In 17 patients the mammary glands prosthesis was conducted using biogel. Biogel did not influence the cell subpopulations of the immunity T- and B-systems, the immunoglobulins level and did not cause the organism sensibilization.
