Abstract
Transplants, particularly from pigskin, from humans, and amniotic membranes of newborns are prepared from the appropriate tissue -- which tissue is treated with the compound glutaraldehyde (GA). The so treated tissue excels by favorable biological function: increased resistance to infection, markedly reduced antigenicity, and prolonged retention time on the recipient, as well as the possibility to store so treated tissue for a prolonged span of time.
Claims25
A process for diminishing the antigenicity of tissues derived from one species when used as a transplant in a different species, for rendering such tissues substantially resistant to infection, and for rendering such tissues liable to be stored for a prolonged period of time, comprising:
- treating the tissue in a solution of glutaraldehyde in an aqueous solvent of suitable pH;
- and
- transplanting the treated tissue into an animal species different than that from which the original tissue was derived.
