A rise of the polysaccharide associated with serum proteins has been noted in malignancy and in several other conditions (7). Seibert, Pfaff, and Seibert (4) determined the carbohydrate content of normal plasma protein fractions isolated by the low temperature ethanolic procedure of Cohn et al. (1) and foundconsiderablecarbohydrateto be associated with all globulin fractions. It would be of int...

Aqueous (hydrophilic) and chloroform (Lipophilic) extracts of nine medicinal plants currently used in Egyptian traditional medicine to treat some gastrointestinal tract (GIT) disorders were tested for their gastro-protective effect against the incidence of peptic ulcer. Indomethacin-induced ulcer in a rat model was used for this testing. Mentha microphylla, Brassica oleracea Capitata (Cabbage),...

Peritoneal exudate macrophages, when exposed to bacterial lipopolysaccharide in culture, were found to produce collagenase (EC 3.4.24.3). This enzyme was not detected in extracts of the macrophages or in media from nonstimulated macrophage cultures. Lipidcontaining fractions of the lipopolysaccharide, including a glycolipid from the rough mutant of Salmonella minnesota (R595) and lipid A, were ...

During the course of investigations on the rela tive therapeutic effectiveness of various bacterial polysaccharide fractions on “metastatic― pul monary tumors induced by the intravenous injec tions of ascites tumor cells in Swiss mice and on the protective ability of cortisone and hydro cortisone in combating the toxicity of the bacterial products (16), it was noted that widespread blood bo...

All the fractions of Phellinus linteus mycelia showed anti-tumor activity toward solid tumors planted in mice. The highest anti-tumor activity of 81.2% was observed in the protein-glucan complex obtained by precipitating the 24% NaOH extract at pH 6.0. This protein-glucan complex consisted of 39.3% polysaccharide and 49.4% protein. Its (13)C- and (1)H-NMR data showed that the main glucan part o...

Both ribonucleic and desoxyribonucleic acids have been obtained from purified particles of PR8 influenza virus. These particles were also found by extraction with formamide to contain carbohydrate in addition to that of the nucleic acids. Carbohydrate-rich fractions, essentially devoid of nucleic acid, were obtained not only from the particles representing PR8 virus but from those of Lee influe...

Here we describe the study of sorption high-molecular components dissolved organic matter (DOM) natural waters - humic acids by eight bacterial strains isolated from freshwater. Isotherms DOM cells are described Langmuir equation. Gram-positive bacteria adsorb more than gram-negative bacteria, with high molecular weight fractions binding in a relatively selective manner. A positive correlation ...
