    Notes: Abstract. There is increasing evidence that phosphorus has been accumulating in the surface horizons of agricultural soils to the extent that some soils represent a potential diffuse source of pollution to surface waters. The relationships between equilibrium phosphorus concentration at zero sorption (EPC 0) of soil and a number of soil physicochemical variables were investigated in the surface layers of arable and grassland agricultural soils sampled from the Thame catchment, England. Soil EPC0 could be predicted from an equation including soil test (Olsen) P, soil phosphate sorption index (PSI) and organic matter content (OM) (R2=0.88; P〈0.001) across a range of soil types and land use. The simple index Olsen P/PSI was found to be a good predictor of EPC0 (R2=0.77; P〈0.001) and readily desorbable (0.02 m KCl extractable) P (R2=0.73; P〈0.001) across a range of soil types under arable having soil organic matter contents of 〈10%.

    Notes: Summary Chronic graft-versus-host disease after bone marrow transplantation presents, in a few cases, as mild to severe scleroderma-like changes. Patients with chronic graft-versus-host disease with and without sclerodermatous skin changes were analysed for antinuclear autoantibodies (ANA) and antinucleolar autoantibodies (ANoA) and the results correlated with disease symptoms and histocompatibility locus antigen (HLA) pattern. Nineteen patients with chronic graft-versus-host disease and scleroderma-like skin changes. 18 with chronic graft-versus-host diseae without scleroderma. and 17 controls on immunosuppressive treatment were screened for ANA and ANoA using enzyme-linked immunosorbent assay, immunodiffusion and immunoblot techniques. Four patients with severe scleroderma had antibodies to topoisomerase I. two had antibodies against PM-Scl. both characteristic serological findings in idiopathic systemic scleroderma. One patient had La/SSB antibodies and, in three cases, antibodies to the nucleolar antigen C23 (nucleolin) could be identified. A possible correlation between antinucleolin antibodies and disease activity was observed. HLA-Al. -B1. and -B2 were found significantly more often in patients with scleroderma-like symptoms in comparison to patients without scleroderma-like symptoms. Chronic graft-versus-host disease with seleroderma-like manifestations can be associated with the occurrence of ANA specific for idiopathic scleroderma. The development of seleroderma after bone marrow transplantation might have a HLA-linked genetic background.
