| antibody induced lysis | <haematology> The term is imprecise and should not be used since there is confusion as to which mechanism is involved, i.e. Natural killing or complement lysis. See: complement lysis, natural killer cells. (09 Feb 1998) |

| tumour lysis syndrome | <haematology, oncology, syndrome> A syndrome resulting from cytotoxic therapy, occurring generally in aggressive, rapidly proliferating lymphoproliferative disorders. It is characterised by combinations of hyperuricaemia, lactic acidosis, hyperkalaemia, hyperphosphatemia and hypocalcaemia. (12 Dec 1998) |
| euglobulin clot lysis time | A measure of the ability of plasminogen activators and plasmin to lyse a clot; normally, clot lysis is determined by the balance of factors which activate fibrinolysis (plasminogen activators and plasmin) and those which inhibit lysis; in certain conditions (e.g., carcinoma or hepatic insufficiency) activating factors predominate and can be measured by noting the time it takes the euglobulin fraction of plasma (excluding inhibitors of fibrinolysis) to clot.
