Momordica charantia Linn. is used as an edible and medicinal vegetable in sub-tropical areas. Until now, studies on its composition and related activities have been confined to compounds of low molecular mass, and no data have been reported concerning the plant's polysaccharides. In this work, a crude polysaccharide of M. charantia (MCP) fruit was isolated by hot water extraction and then purif...

BACKGROUND & OBJECTIVES The extracts from Caltha palustris L. have been shown to be beneficial for treating arthritis and rheumatism. In this study, the immunomodulatory effects of polysaccharide fractions B and C of C. palustris extracts were studied, using the collagen-induced arthritis (CIA) mouse arthritis experimental model. The aim was to determine the activity of blood phagocytic cells a...

review of the clinical reports, and of animal experi mentation, on the influence of bacterial toxins on malignant tumors, since the method was first used by W. B. Coley in 18992. Beebe and Tracy (92)found that suspensions of Bacillus prodigiosnie, Streplococcn3 pyogenes, Staph ylococcus aurens, and B. coli communis caused regression of large transplanted lymphosarcomas in the dog. Similar resul...

The crude polysaccharide extracted from the flowers of burley tobacco hybrid Eyan 1 was fractionated on a Sepharose CL-6B chromatography to get two purified polysaccharide fractions (termed Fr-I and Fr-II). The monocarbohydrate compositions revealed both fractions were heteropolysaccharide. Fr-I was mainly composed of mannose, galactose, ribose and arabinose, while Fr-II was composed of mannose...

1. A procedure for the isolation and purification of the heparin-protein complex from ox liver capsule, based on the solubility properties of mucopolysaccharide-cetylpyridinium complexes, is described. 2. The yield of the heparin-protein complex with this method averages 35mg./100g. of dry ox liver capsule. 3. The results of analyses on the polysaccharide show good agreement with values previou...

Serological relationships between antigenic fractions of Actinomyces and Nocardia. J. Bacteriol. 86:179-186. 1963.-A total of 52 chemical fractions were obtained by a comprehensive technique of preparation from three strains of Actinomyces and three strains of Nocardia. The che...

Using high resolution molecular technique of atomic force microscopy, we address the extracellular polymer production of Adriatic diatom Cylindrotheca closterium analyzed at the single cell level and the supramolecular organization of gel phase isolated from the Northern Adriatic macroaggregates. Our results revealed that extracellular polysaccharides freshly produced by marine diatoms can self...

Protein-rich wheat bran aqueous extract was fractionated by size exclusion chromatography. Each of the chromatographic fractions hydrolyzed with V8 protease in a reaction medium containing Ca2+. Both and hydrolysates were characterized physically chemically. The objective to obtain information about which components are involved formation nanoparticles, reported previous works. Six from 0.3 102...
