title: K-cell activity in aplastic anaemia.
abstract: K-cell activity was measured by specific cytotoxicity and cytotoxic capacity in 29 patients with aplastic anaemia. 9 patients had a reduction of the specific cytotoxicity and 12 had a decreased cytotoxic capacity. The decreased cytotoxic capacity correlates with the severity of aplastic anaemia. Some of the possible causes of the reduction of this activity were investigated.
