摘要:
A polysulfone hollow fiber membrane for blood purification which has no danger that any component of the membrane dissolves out, and which can be used suitably or hemodialysis and blood filtration and remove selectively and efficiently low-molecular-weight proteins having molecular weight of 10,000 to 30,000 contained in blood, as well as a blood purifier which can be used suitably as a hemodialyzer, a filter for hemodiafiltration and a blood filter are provided. The hollow fiber membrane comprises a polysulfone resin, wherein there are slit-shaped micropores having an average width of 0.02 to 0.15 .mu.m on the inner surface thereof; there are micropores having an average pore size of 0.1 to 1 .mu.m on the outer surface thereof; the inside thereof has a sponge-like structure; there are no large voids having a diameter of more than 10 .mu.m on the inner and outer surface thereof and inside the membrane; water permeability thereof is 400 to 2,500 ml/m.sup.2 .multidot.hr.multidot.mmHg; and a permeation rato for the total proteins is 1% or less. The blood puifier contains the hollow fiber membrane put into a cylindrical housing which is equipped with a blood inlet and a blood outlet, and either a dialysate solution inlet and a dialysate solution outlet or a filtrate outlet.
摘要:
An object of the present disclosure is to provide a fuel cell separator having a low contact resistance due to a tin oxide film and having an excellent corrosion resistance. An embodiment is a method for manufacturing a fuel cell separator including a stainless steel substrate. The method includes forming the tin oxide film on a surface of the stainless steel substrate; and attaching phosphoric acid or phosphate to at least a defective portion in the tin oxide film.

An adsorbent for removing a chemokine except interleukin-8 in body fluid, which comprises a solid material having an anionic functional group, a method for efficiently removing a chemokine except interleukin-8 in body fluid, which comprises by bringing the above adsorbent into contact with body fluid containing the chemokine and an adsorber for removing a chemokine except for interleukin-8 using the above adsorbent.
摘要:
A water-repellent and oil-repellent coating, which can exert high water-repellency and oil-repellency not only at ordinary temperature, but also even after exposure to a high temperature and whose environmental burden is low, is formed by dehydration condensation of perfluoroaryl trisilanol (at least one fluorine atom in its perfluoroaryl group may be substituted with a trifluoromethyl group) having a molecular structure in which not only functional groups which presents a surface energy, such as a methylene group, a methylene group, an ether linkage (oxygen atom), a carbonyl group, etc., but also a difluoromethylene (—CF2—) group have been eliminated.
摘要:
An adsorbent for cardiac glycoside contained in body fluid, comprising a compound having a log P value of at least 6 immobilized on a water-insoluble carrier is provided. A process for adsorbing and removing cardiac glycoside contained in body fluid efficiently, which comprises contacting body fluid with this adsorbent for cardiac glycoside is provided.
摘要:
An apparatus for purifying blood which is able to separate blood into plasma and blood rich in blood cells, to purify the separated plasma and to mix the purified plasma into the blood stream simultaneously by itself.The apparatus has two parts, i.e. a blood flowing system in which the blood is separated by means of porous hollow fibers provided in a container and the purified plasma is mixed into the blood stream through the hollow fibers, and a plasma flowing path in which the separated plasma is circulated and purified at a plasma purifying device provided on the way of the path.The apparatus has a simple structure and can be operated without any specific cares and difficulty. The apparatus is free from any problems, for instance, hemolysis, fiber blockage, mixing of the purifier particles into blood, and the like.
