A composition for promoting bacterial proliferation and selectively proliferatingsubsp.is disclosed, which includes a dextran. A variety of biological activities originating fromsubsp.can be sustained in a living body by selectively growing-proliferating and colonizingsubsp.in the intestine of a human being, animal, or the like or by selectively growing-proliferatingsubsp.in the intestine, without supplyingsubsp.at all times.

A droplet operation device has a substrate with light transmissibility and having been subjected to a water repellent treatment, a way for supplying droplets onto the substrate, a way for transporting the droplets on the water repellent substrate, and a way for measuring the state of the droplets. The droplet operation device includes the light transmittable substrate, solvent feeding ports for leading reagent or specimen droplets onto the substrate, optical measuring units, and electric field application units. As a result, the inside of the droplets can be observed with a microscope, and results of the reaction of the droplets against other droplets can be measured and classified by stopping and moving the droplets in any direction.

A DNA encoding a cell surface polypeptide of,, 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 oxygen-permeable polymer is prepared by polymerizing (1) at least one first monomer selected from the group consisting of alkenes of 6-10 carbon atoms having one double bond and one side chain methyl group, and (2) at least one second monomer selected from the group consisting of (fluoro)siloxanylalkyl mono(meth)acrylates, (fluoro)siloxanylalkyl di(meth)acrylates, fluoroalkyl (meth)acrylates, alkyl (meth)acrylates, .alpha.-alkyl- or .alpha.-fluoroalkyl-acrylic acids, alkyl .alpha.-alkylacrylates, alkyl .alpha.-fluoroalkylacrylates, fluoroalkylacrylates, fluoroalkyl .alpha.-fluoroalkylacrylates and fluoroalkyl .alpha.-ackylacrylates, the copolymerization proportions of the first monomer and the second monomer being such that the first monomer ranges from 5-80% by weight and the second monomer ranges from 20-95% by weight. The polymer produced by the process has very high oxygen permeability, is resistant to adhesion and adsorption of staining substances present in lacrima or intraocular solution, and has excellent machinability and grindability.
