Polysaccharide from Dura mater By Yoshiharu Saito and Koh-Iti Turumi (齋 藤 義 治) (鶴 見 膠 一) From the Department of Biochemistry, Fukushima Medical College, Fukushima (Received for publication, October 10, 1954) Chemical studies of dura mater has not as yet been accomplished. Histologicaly dura mater is composed of connective tissue. We examined the tissue histochemically by periodic acid oxidation...

In a previous investigation conducted in this laboratory (1) a starch polysaccharide, apparently identical with the watersoluble component of the common cereal and tuber starches, was isolated from the woody tissue of the apple tree (Malus malus). Thus it appears that starches of widely different origin may contain a common water-soluble polysaccharide. Through an application of the method (2) ...

The vaccine of whole cells inactivated by heat and phenol that has been used in Cuba since 1983 is highly reactogenic and has shown little epidemiological impact. A technology was developed to substitute this vaccine for a Vi Polysaccharide of new generation, competitive with those existing in the international market. The technology developed is characterized by a new medium that maximizes the...

BACKGROUND Orodispersible tablets or fast dissolving tablets dissolve or disintegrate immediately on the patients' tongue or buccal mucosa. This drug delivery system is suitable for drugs undergoing high first pass metabolism. It improves bioavailability, reduces dosing frequency, and thereby minimizes the side effects and also makes the dosage form more cost-effective. In this study, polysacch...

We have studied the dynamics of the motion of a complex polysaccharide having seven sugar residues in the repeating subunit and which is a receptor for lectin interaction in the coaggregation of oral bacteria. Measurements of the longitudinal and the rotating frame relaxation rates and the heteronuclear nuclear Overhauser effects were carried out on a uniformly 13C-enriched sample using pulse s...

The objective of the present work was extraction of polysaccharide from Senna tora L. seed and its characterization as a pharmaceutical excipient. Polysaccharide extraction was based on mechanical separation of the endosperm of seeds of Senna tora, water dissolution, centrifugation, and precipitation with acetone. Standard procedures were used to study the viscosity, micromeritic properties, an...

The recognition of bacteria, viruses, fungi, and other microbes is controlled by host immune cells, which are equipped with many innate immunity receptors, such as Toll-like receptors, C-type lectin receptors, and immunoglobulin-like receptors. Our studies indicate that the immune modulating properties of many herbal drugs, for instance, the medicinal fungus Reishi (Ganoderma lucidum) and Cordy...

Our previous study revealed that the antioxidant activity of polysaccharide (coded as FGFP) extracted from Grifola frondosa by enzymolysis treatment was significantly superior than that (coded as GFP) extracted by boiling-water. In this study, one purified polysaccharide fractions (coded as FGFP-11) was obtained from FGFP by purified using DEAE-52 column and Sephacryl S-500HR column. Results in...
