1. Immune RNA (iRNA) was extracted from the spleen of a sheep immunized with human immunodeficiency virus (HIV) antigens. 2. The transfer of cell-mediated immunity to HIV antigens was accomplished by injecting iRNA into a Cebus monkey, as evaluated in vitro by leukocyte migration inhibition. The in vitro treatment of normal human leukocytes with iRNA also(More)
T lymphocytes from rats with malignant fibrous histiocytoma at different stages of tumor growth were investigated for sensitization to bovine myelin basic protein (MBP). The immunological reactivity was assessed by a leukocyte adherence inhibition assay as an in vitro correlate of cellular immunity. We found that only T lymphocytes obtained 4 and 6 days(More)
1. In order to evaluate hepatic trophism in diabetic dogs, an experimental study was carried out on 30 adult mongrel dogs of both sexes weighing 11.9 +/- 1.6 kg, divided into three groups: 1) Controls (C) (N = 10), submitted to partial (30%) hepatectomy; 2) PD Animals (N = 10), submitted to partial hepatectomy plus total pancreatectomy with preservation of(More)
