Peripheral blood lymphocytes (PBL) from 15 of 38 patients with chronic lymphocytic leukaemia (CLL) were capable of forming rosettes with human erythrocytes coated with staphylococcal protein A (SpA-HRBC). PEL from seven patients also showed a marked proliferafive response after stimulation with Staphylocccus aureus bacteria strain Cowan I (Cowan Staph). The SpA-rosetling of CLL cells was inhibited by incubation with F(ab')2 fragments of anli-immimoglobuiin (Ig) antibodies. In addition, incubation with these fragments inhibited the proliferative response of leukacmie B cells to Cowan Staph. The Cowan-Siaph-induced proliferation of CLL cells was also impaired by the addition of normal human IgG and human IgG F(ab')2 fragments to the cultures, whereas non-immune rabbit IgG was not inhibitory, The inhibitory activity of human IgG F(ab')2 fragments was retained hy a SpA-Sepharose column, and it was found in the material recovered from the same column by acid elution. These data indicate thai an interaction between SpA and a structure located in the F(ab')2 region of surface Ig of different classes is responsible for either SpA-binding or the Cowan-Staph-induced proliferate response of PBL from some patients with CLL. 相似文献

A modified version of the McGill Pain Questionnaire in visualanalogue format was used to evaluate the sensory, affectiveand evaluative intensities of pain experienced by 40 patientswith rheumatoid arthritis and 20 patients with degenerativearthritis. The affective component of the pain was found tobe more intense than the sensory component in all patients indicatingthe importance of emotional factors in the pain experience.The sensory aspects of the pain were more complex than the affectiveones reflecting the varied sources and combinations of somaticpathology. There were no significant differences found in theoverall pain experience between rheumatoid and degenerativearthritis. No differences were noted in the evaluative categoryof pain. Overall pain intensity increased with disease durationin both rheumatoid and degenerative arthritis. The relationshipof affective and sensory components of the pain experience didnot alter with duration of disease. KEY WORDS: Arthritis, Pain 相似文献
