The effects of furosemide and 4-acetamido-4'-isothiocyanostilbene-2,2'-disulfonic acid (SITS) on steady-state Cl- flux were studied in Ehrlich mouse ascites cells. At 10 mM, furosemide inhibited isotopically-determined Cl- flux by 86% without changing cell Cl- content, indicating that influx and efflux were depressed by the same amount. These results(More)
Plant lectins or phytohemagglutinins possess potent in vivo biological activities. Some, primarily of the family Leguminosae, have been shown to have deleterious nutritional effects. Little information exists, however, regarding the prevalence of lectins or the specific foods that contain lectins in the United States diet. In the present study the edible(More)
Several aspects of the interaction of various lectins with the surface of Ehrlich ascites carcinoma cells are described. The order of agglutinating activity for various lectins is Ricinus communis greater than wheat germ greater than or equal to concanavalin A greater than or equal to soybean greater than Limulus polyphemus. No agglutination was noted for(More)
The diterpene ester 12-O-tetradecanoylphorbol-13-acetate (TPA) and several structurally related compounds were tested for their ability to stimulate interferon (IFN) production in primary cultures of human leukocytes. In cultures of Ficoll-Hypaque-purified mononuclear cells, TPA treatment alone induced only low levels of IFN, but TPA pretreatment of cells(More)
OBJECTIVES To develop and evaluate a web-based curriculum to introduce first year medical students to the knowledge and attitudes necessary for working with limited English proficient (LEP) patients through interpreters. METHOD Six hundred and forty first year medical students over 4 consecutive years took this curriculum as part of their Patient(More)
INTRODUCTION Alcoholics Anonymous is not yet fully employed by the medical community as a means to enhance patient outcome. The purpose of this study was to evaluate visitors' use of an Internet course on Alcoholics Anonymous, and to compare how various disciplines learned about, gained access to and participated in the course.
