Abstract: An intestinal microflora-improving agent containing, as an effective component, bacterial cells and/or the water-soluble extracts therefrom, obtained from microorganisms belonging to the genus Streptococcus.

Abstract: A hypotriglyceridemically active polysaccharide having the following characteristics:(a) Specific rotatory power:[.alpha.].sub.D.sup.29 =+190.1(1.8 w/v % solution)(b) Molecular weight by gel filtration:14,000.+-.3,000(c) Sugar composition (weight percent by gas chromatography)glucose: 70.3rhamnose: 13.7uronic acid: 16.0(d) Acid-base characteristic:neutral polysaccharides(e) Physiological characteristics:capable of reducing the blood triglyceride in mammals.This hypotriglyceridemically active polysaccharide can be prepared by cultivating a microorganism belonging to the genus Streptococcus in an adequate culture medium therefor; and collecting the hypotriglyceridemically active polysaccharide from the cultured cells of the microorganism and/or the supernatant of the culture broth.

Abstract: A bacterial cell product having hypocholesterolemic and/or hypotriglyceridemic activity in mammals obtained by cultivating a microorganism belonging to the genus Streptococcus and having a N-acetyl-.beta.-D-glucosaminidase activity in an adequate culture medium therefor, and collecting the cultivated microorganism from the resultant culture.

Abstract: A magnetic sheet cassette device consisting of a rigid casing and a magnetic sheet housed therein, featured in having cavities between the recording faces of the magnetic sheet and the casing for preventing abrasion or damage by bending of the recording faces, featured further in having plural apertures in the casing corresponding to the index hole of the magnetic sheet in order to allow detection thereof with a single photocoupler even when the cassette device is inverted, and featured in having an aperture for prohibiting information write-in in a part of the cassette device in order to prevent erroneous erasure of the recorded information.
