We have utilized the blast cell assay of Buick et al. (1977) to grow and subsequently cytogenetically analyze cultured colony forming cells (CFUs) from patients with acute and chronic myelogenous leukaemia (AML, CML). Cytogenetic analysis of CFUs was successful in 30/36 cases (83%), a success rate similar to direct harvesting techniques. Identical clonal(More)
Four adult, chronic psychotic inpatients were observed before, during and after the contingent application of time-out. Time-out was a part of their individual treatment programs, and consisted of placement in a furnitureless room for 15 minutes. Observations were made of 16 behaviors grouped into seven categories; these categories included both consequated(More)
