The aim of this study was to evaluate the screening policies of cystic fibrosis (CF) in the Jewish population. The prevalence of mutations that account for CF in Israel have been defined in the past by determining the frequency of CF mutations in affected individuals. This study is a population-based study and is, therefore, different from previous(More)
Forty-nine Israeli Jewish patients with rheumatoid arthritis (RA) were studied for their HLA A, B, C, DR antigen frequency. A significant increase in HLA Aw31 and HLA DR1 was observed (p less than 5.10(-5) and p less than 5.10(-3) respectively). 45% of Aw31 positive patients were sero-negative for rheumatoid factor, while most HLA DR1 positive individuals(More)
During the period from 1978 to 1981, 52 patients with ALL were diagnosed and treated at the Chaim Sheba Medical Center. Using standard cell markers to subtype the blasts, 49 of the patients could be classified: 16 were found to be T-cell ALL, 10 common ALL, five null ALL, four pre-B and 14 were partially characterized as non-B, non-T. Analysis of the series(More)
Habitual abortion is a difficult clinical problem, as no cause can be found for abortion in over 50% of patients. At the habitual abortion clinic of the Sheba Medical Center, immunological activity is tested and patients who are considered suitable are offered immunopotentiation with paternal leukocytes. Patients are only treated if they have no other cause(More)
Thymus lymphocytes of normal adult rats were autosensitized in vitro against soluble antigens extracted from the brains of syngeneic rats. Injection of the autosensitized lymphocytes into syngeneic rats led to the development of brain lesions suggestive of autoimmune encephalomyelitis. Injection of control lymphocytes or the antigen extract alone did not(More)
Palindromic rheumatism is very rare in children. The familial occurrence of the disease has been only briefly reported previously. A family is described here in which the mother and her 3 children suffered from typical palindromic rheumatism, which ran a benign course. All 4 members were seronegative and the HLA types of the children were identical. The HLA(More)
The presence of extra HLA antigens has been demonstrated, serologically and biochemically, on the surface of lymphoblasts from a patient with acute lymphoblastic leukemia of the T-cell subtype (T-ALL). Family analysis of this patient revealed the presence of the expected antigens, plus an additional HLA antigen (A24) which could be demonstrated by(More)
