Abstract: Functional histocompatibility testing wherein stimulator calls, which are lymfocytes of a potential organ transplant donor or recipient that have been treated to become incapable of proliferation, are cocultured with responder cells, which are lymfocytes of a potential organ transplant recipient or donor that are capable of proliferation and include cytotoxic effector cells, and degranulation of said cytotoxic effector cells is determined. The degranulation of cytotoxic effector cells, such as Cytotoxic T Lymfocytes and Natural Killer cells, may be determined by measuring a granule consistituent, such as a granzyme or perforin, by means of an immunoassay in the coculture supernatant. This new method of functional histocompatibility testing may be used after a preliminary selection of donor-recipient pairs by means of HLA typing.

Abstract: A therapeutic or prophylactic treatment method of acute myocardial infarction, comprising administering exogenous C1-esterase inhibitor, alone or in combination with other drugs, to a patient with acute myocardial infarction or to a patient at risk for acute myocardial infarction. The treatment inhibits the inflammatory reaction, more specifically the activation of the complement system, which occurs in the course of acute myocardial infarction. The C1-esterase inhibitor may include C1-esterase inhibitor purified from plasma or other biological materials, or recombinant C1-esterase inhibitor, or recombinant variants derived therefrom, or recombinant constructs of other inhibitors having a specificity similar to C1-esterase inhibitor.
