In this study we tested the seeds of uncultivated plants for lectin activity. Extracts prepared from the seeds of 167 forb species were tested against human red cell samples. Extracts of 54 species agglutinated unmodified or enzyme-modified red cells. In nine species, the hemagglutinating lectin activity could be neutralized by N-acetyl-D-galactosamine,(More)
OBJECTIVES To identify and compare the incidence, demographics, neurologic presentation, and functional outcome of individuals with nontraumatic spinal cord injury (SCI) to individuals with traumatic SCI. DESIGN A 5-year prospective study. SETTING Level I trauma center of a Regional SCI Model System. PATIENTS Two hundred twenty adult SCI admissions.(More)
Two hundred four examples of blood group antibodies, reactive only by the indirect antiglobulin test, were examined by the two-layer albumin capillary (TLAC) technique. Fifty-nine per cent of the examples tested were reactive by this technique. TLAC reactivity appeared to be related to antibody specificity, but a positive association between TLAC reactivity(More)
This report documents a mild case of hemolytic disease of the newborn (HDN) associated with anti-Jk3. The Filipino mother had previously had six children none of whom had been affected by HDN. She had been transfused at the time of her second pregnancy. Anti-Jkb and anti-Jk3 were detected in the maternal serum at the time of her seventh delivery. No(More)

Human blood group antibodies of 11 specificities were examined for ability to mediate interaction with normal blood monocytes, IgG subclass composition, and titer score. Most antibodies were normally non-complement-binding (except anti-JKa) and clinically significant (except anti-Lub). A simple and relatively rapid in-vitro assay for the visualization of(More)
Two red blood cell (RBC) units labeled group B were returned to the source blood center after they had been retyped as AB by a transfusion service. The discrepancy could be reproduced, but only with the use of the transfusion service's reagent, Ortho Diagnostic's anti-A Bioclone (a licensed, blended, murine monoclonal anti-A reagent). RBCs from 35 of 3,458(More)
The purpose of this study was to develop educational software to simulate laboratory investigation of transfusion reactions. An interactive, branching-style program was developed using a 256K Personal Computer (International Business Machines, Boca Raton, FL). Over 75 institutions in the United States and Canada are currently using the software in(More)
The purpose of this study was to determine and to compare the titers of salivary anti-A and anti-B antibodies in two groups of patients with periodontal disease as measured by Russell's Periodontal Index (PI). Forty volunteer subjects, who were new patients assigned to a screening clinic, were selected for the study based on the following criteria: (1)(More)
