Increased Natural Killer Cells Activity in Schizophrenic Patients
Background: Schizophrenia has been associated with altered immunity. Different studies regarding natural killer cell activity (NKA) in schizophrenic patients have shown inconsistent results. Objectives: To evaluate NK cell activity in schizophrenic patients in comparison with healthy control individuals. Methods: 30 medication-free schizophrenic patients and 41 healthy sex, age and smoking st...
متن کاملNatural killer cell activity in lung cancer patients.
A total of 50 lung cancer (CA) patients and 20 normal persons as controls were included in our study. We obtained lymphocytes from heparinized blood by Ficoll-Hypaque gradient method, and after the macrophages were removed, they were incubated with 51Cr-labelled K562 cells at concentrations of 100:1, 50:1, 12.5:1 for four hours. We calculated the cytotoxicity activity and lytic unit (LU) of nat...
متن کاملDefects in natural killer cell activity and interferon response in human lung carcinoma and malignant melanoma.
The natural killer (NK) activity of peripheral blood mononuclear cells from 25 patients with squamous cell carcinoma of the lung, malignant melanoma, or epitheloid cancers of the gastrointestinal tract was measured by the lysis of 51Cr-labeled K562 target cells. NK activities of many patients with lung cancer or malignant melanoma were decreased relative to normal controls. This abnormality was...

متن کاملMedullasin enhances human natural killer cell activity.
Medullasin, a new serine protease found in bone marrow cells, increased markedly human natural killer cell activity. Whereas the natural killer cell activity measured immediately after the treatment with medullasin remained almost on the same level as the control, an incubation at 37 degrees C for several hours increased markedly the natural killer cell activity of the lymphocytes treated with ...
