Type II arabinogalactan (AG) is a polysaccharide found in Maytenus ilicifolia (Celastraceae), a plant reputed as gastroprotective. Oral and intraperitoneal administration of the AG protected rats from gastric ulcers induced by ethanol. No alteration of mechanisms related to acid gastric secretion and gastrointestinal motility were observed. In vitro, the AG showed a potent scavenging activity a...
The transglycesylation reaction was done with a fi-ga)actanase from Penieillium eitrinum. The regioseiectivity in the transglycosylation reaction was studied using soy bean arabinogalactan as a donor and monoeT disaccharide derivatives containing fi-galactosyl residue as accepters. We also synthesized oligosaccharides eontaining Galfi1.4Gal sequence such 2s Galfi1.4GalPl.4G]c, Galfi1.4Galfi1. 3...
Evidence suggests that as platelets age in the circulation they become progressively smaller and less dense through the loss of protein. The smallest, least dense platelets have a significantly shortened survival, but the mechanism of clearance of these platelets is not known. To evaluate whether the binding of IgG could play a role in the clearance of senescent platelets, we measured platelet ...
We have identified a family of abundant peripheral plasma membrane glycoproteins that is unique to flowering plants. They are identified by a monoclonal antibody, MAC 207, that recognizes an epitope containing L-arabinose and o-glucuronic acid. Immunofluorescence and immunogold labeling studies locate the MAC 207 epitope to the outer surface of the plasma membrane both in protoplasts and in int...
