[receptors of human red blood cells for anti-tah and anti-ahp in the course of intravascular aging].	human o-erythrocytes aged in situ do not expose free receptors for anti-t agglutinin of arachis hypogea. new receptors for concentrated anti-a agglutinin of helix pomatia are manifested but are lost again in the course of further ageing of the cells in situ. a remasking of exposed receptors for anti-tah and anti-ahp byautologous, strongly binding globulins is supposed. these globulins could constitute the decisive signal for the autologous phagocytosis of senescent red blood cells.	1979	525143
[lectins as reagents for the differentiation of serum enzymes. lectins as reagents, i. (author's transl)].	lectins from canavalia ensiformis, phaseolus vulgaris, and triticum vulgare react with arylamidase, alkaline phosphatase, gamma-glutamyltransferase, and cholinesterase of human sera by formation of enzymatically active, mostly insoluble complexes. arylamidase, alkaline phosphatase, and cholinesterase react more intensely in sera of healthy people than in sera of patients with liver and neoplastic diseases. arylesterase is bound to a distinct degree only by concanavalin a. the enzymes mentioned a ...	1979	547035
concomitant t- and tk-activation associated with acquired-b antigens.	three patients with acquired-b antigens are reported whose red blood cells also manifested t- and tk-activation. the results of tests using purified arachis hypogaea and bandeiraea simplicifolia (bs ii) lectins, and red blood cells either t, tk or both t and tk-activated by bacterial enzymes in vitro, suggest that the acquired-b phenomenon, t-activation and tk-activation result from the action of different bacterial enzymes.	1979	222015
immuno-chemical studies on the alkali-labile carbohydrate chains of human serum glycoproteins.	human serum glycoproteins can be classified into those containing n-acetyl-d-galactosamine and into those lacking this hexosamine. the n-acetyl-d-galactosamine-containing serum glycoproteins have alkali-labile chains containing this hexosamine linked o-glycosidically to hydroxy amino acids. these alkali-labile chains can be demonstrated in neuraminic acid free serum glycoproteins by gas liquid chromatography and by using precipitating lectins from invertebrates and plants. they are represented b ...	1979	762504
distribution of lectins in the jumbo virginia and spanish varieties of the peanut, arachis hypogaea l.	peanut lectin was purified from seed meal of the spanish and jumbo virginia varieties of peanut (arachis hypogaea l.) by affinity chromatography on lactose coupled to sepharose 4b. polyacrylamide gel isoelectric focusing resolved the lectin preparation from jumbo virginia seeds into seven isolectins (pi 5.7, 5.9, 6.0, 6.2, 6.3, 6.5, and 6.7). seed meal from the spanish variety contained six isolectins which were indistinguishable from the pi 5.7, 5.9, 6.2, 6.3, 6.5, and 6.7 isolectins from jumbo ...	1979	16661012
light effects on development of an indeterminate plant.	the peanut (arachis hypogaea l.) plant is indeterminate in growth habit and day-neutral with respect to flower initiation. the spanish-type cultivar used in this study begins flowering 3 to 4 weeks from planting under optimum environmental conditions. in this study, irradiance and photoperiod were used to alter the development of the peanut plant. plants grown at low irradiance (300 microeinsteins per square meter per second) had the same number of leaves as the plants grown at high irradiance ( ...	1979	16661030
