摘要:
A composition for promoting bacterial proliferation and selectively proliferating Lactobacillus casei subsp. casei is disclosed, which includes a dextran. A variety of biological activities originating from L. casei subsp. casei can be sustained in a living body by selectively growing-proliferating and colonizing L. casei subsp. casei in the intestine of a human being, animal, or the like or by selectively growing-proliferating L. casei subsp. casei in the intestine, without supplying L. casei subsp. casei at all times.

摘要:
A DNA encoding a cell surface polypeptide of Porphyromonas gingivalis, and a recombinant DNA being a DNA having integrated said DNA thereinto. The cell surface polypeptide of the periodontopathic organism useful for prophylaxis and diagnosis of periodontal diseases can be obtained in a large amount by a microorganism containing the recombinant DNA wherein the DNA was integrated.

An SAR ADC includes a digital-to-analog converter, a first comparator that compares an input analog signal with a reference analog signal, a second comparator that compares an input analog signal with a reference analog signal, a selection circuit that selects one of comparison results of the first comparator and the second comparator, and a control circuit that changes the multibit digital signal sequentially based on the selected comparison result in a plurality of steps so that the reference analog signal becomes closer to the input analog signal, and the control circuit controls the selection circuit to select the comparison result of the first comparator up to an intermediate step on the way of the plurality of steps and to select the comparison result of the second comparator after the intermediate step, and changes the bit value of the multibit digital signal according to the non-binary algorithm.
摘要:
There are provided peptides (each having 5 to 10 amino acid residues) corresponding to fragments derived from the amino acid sequence of the 41 kD sub-unit protein constituting the fimbriae of Porphyromonas gingivalis, or salts of the peptides. Further provided are compositions for diagnosis of periodontal disease containing them, vaccines for prophylaxis of periodontal disease containing part of them, and the oral compositions for prophylaxis or treatment of periodontal disease containing antibodies obtained by immunizing animals with the peptides.Peptides are provided which are lowered in nonspecific reactivity and can be used more safely for the above compositions, compared to the above protein and peptides therefrom having 20 amino acid residues.

A lens hood device includes a barrier case (11) to cover the front and back of a lens barrier unit (32) in an optical axis direction and to have a non-circular opening at a position passed by the optical axis, and a plurality of lens barriers (14 to 17) arranged rotatably in parallel with respect to a main plane of the barrier case (11) and made rotatable between a position to cover the whole face of the opening and a position to open the opening. The lens barriers (14 to 17) are contained in the barrier case (11) in order not to be exposed at the opening, when they are positioned to open the opening. The thus provided lens hood device can improve the operability without enlarging the size of an image pickup device.

摘要:
A novel disaccharide derivative represented by the following formula, which is the compound of the present invention, its stereoisomers and salts and a medicinal composition comprising the same as an active ingredient. ##STR1## The compound of the present invention has various biological activities, for example, potent mitogenic activity, adjuvant activity, polyclonal B cell activating (nonspecific protective) activity, natural killer activity, antitumor activity, antiviral activity, etc. but little harmful effects, for example, function of inducing the production of so-called inflammatory cytokines such as tumor necrosis factor (TNF) and IL-1 from macrophages. Therefore it is highly useful as an immunopotentiator, an antitumor agent, an antiviral agent as well as an agent for preventing and treating sepsis, chronic rheumatoid arthritis, etc. without showing any harmful effects such as lethal toxicity or pyrogenicity as observed in the conventional lipid A and derivatives thereof.
