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)
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)
The way in which the lectins concanavalin A (Con A) and Ricinus communis agglutinin (Ricin) alter the K+ content of Ehrlich ascites tumor cells was investigated. Unidrectional and net fluxes were determined in unwashed cells during a time course following lectin addition. Total influx, ouabain sensitive influx, Mg++- and Na+-K+-ATPase activity were all(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)
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)
