Abstract
A biologically active form of vitamin D, 1,25(OH)2D3, and a leukocyte surface molecule, CD23, play important roles in immune regulation. The effect of 1,25(OH)2D3 on the CD23 gene expression was examined in this study. The results show that 1,25(OH)2D3 suppresses spontaneous and IL-4-stimulated CD23 synthesis by peripheral blood monocytes. The inhibition occurs at both the protein and mRNA levels. However, 1,25(OH)2D3 has no inhibitory effect on CD23 production by either resting or activated tonsillar B cells. Our results suggest a possible role of 1,25(OH)2D3 in the regulation of certain immune and inflammatory responses via its effect on CD23 production.

Abstract
The presence of minute amounts of embryonic zeta-globin chains in adult hemolysates is a marker for carriers of alpha-thalassemia-1 resulting from (--SEA/) deletion. Recently, we developed a murine monoclonal antihuman embryonic zeta-globin chain antibody, 8E8. By using this antibody, we have now established a slot-blot immunobinding assay for the rapid detection of zeta-globin chains in adult hemolysates. zeta-globin chains were found to be present in 30 blood samples obtained from individuals who were carriers of alpha-thalassemia-1. In another 30 blood samples from individuals who were not carriers of the (--SEA/) deletion, zeta-globin chains were not detected. This simple diagnostic test can be used in appropriate populations to identify those couples at risk of conceiving fetuses afflicted with the Hb Bart's hydrops fetalis syndrome due to homozygous alpha-thalassemia.

Abstract
Human embryonic epsilon globin chains were isolated from lysates of cultured human leukemic K562 cells induced with hemin. Mice were immunized with epsilon globin chains, and a murine hybridoma cell line was established that secreted monoclonal anti-epsilon globin antibody. A sensitive and specific slot blot immunoassay for epsilon globin chains has been developed. epsilon Globin chains were shown to be present in hemolysates from fetuses of 20 weeks' gestation but were not detected in normal cord blood hemolysates. This immunoassay is useful for the study of epsilon globin ontogeny during embryonic and fetal development as well as for searching for inappropriate epsilon globin chain expression in hematologic disorders resulting from genetic abnormalities or neoplastic processes.

Abstract
A murine hybridoma cell line secreting monoclonal anti-human embryonic zeta-globin chain antibody has been established. Using this monoclonal antibody, a slot blot immunobinding assay for the detection of zeta-globin chains in adult hemolysates has been developed. This simple test can identify individuals who are alpha-thalassemia-1 carriers due to the (-SEA/) deletion. It is proposed that this test should be made generally available in Southeast Asia and Southern China, in order to identify couples who are at risk of begetting fetuses afflicted with homozygous alpha-thalassemia.
