Peripheral blood lymphocytes were separated into HNK-l+ and HNK-l− subpopulations and
examined for the effects of prednisolone (PRD) on natural killer cell activities in vitro …

The in vitro effect of prednisolone (PRD) on NK and ADCC activities of human lymphocytes
was investigated. PRD at concentrations ranging from 7.5 X 10 (-3) to 1 X 10 (-5) M …

Natural killer (NK) cells have spontaneous cytotoxic activity which can be augmented or
suppressed by a wide range of stimuli [1, 2], and which does not depend on prior …

Investigations into the mode of action of glucocorticoids on natural killer (NK) cell activity
have been hindered by the lack of an in vitro model system. We report that the NK activity of …

Natural Killer (NK) activity has been shown to be depressed under stressful conditions.
Glucocorticoids, which are known to increase during stress, seem to negatively regulate the …

The NK cell activity of mononuclear cells as well as monocyte‐depleted, Percoll‐
fractionated, NK cell‐enriched effector cells against K 562 target cells was inhibited by …

Lymphocytes mediating natural killer (NK.) and antibody-dependent cellular cytotoxicity
(ADCC) activities are relatively refractory to the changes in circulatory traffic and intrinsic …

In this study we investigated the modulation of natural killer (NK) cell activity by various
histamine receptor antagonists in vitro. The histamine H2-receptor antagonists cimetidine …

Athymic (nude) rats were found to have increased levels of natural killer (NK) activity, 3− to
5− fold higher than in euthymic rats. Studies were performed to determine the nature of the …

The in vivo and in vitro effects of indomethacin on the natural killer (NK) cell activity against
K 562 target cells were studied In vivo administration of indomethacin, 3× 50 mg for 7 days …
