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.

A device for body fluid purification, comprising a container having an inlet and an outlet for a fluid and a means for preventing an adsorbent from flowing out of the container and an adsorbent charged in the container, the adsorbent comprising a spherical hydrogel, the spherical hydrogel having an average particle size in a range of from about 460 to 600 μm and having a substantially uniform particle size and comprising an epoxidated cellulose having hexadecylamine immobilized thereon in an amount of 100 to 300 μmol per gram of dry weight of said epoxidated cellulose, and water, wherein the weight ratio of said epoxidated cellulose having hexadecylamine immobilized thereon to the water is 2:8.
摘要:
An adsorbent for removing at least one interleukin selected from the group consisting of inerleukin-1, interleukin-2, interleukin-6 and interluekin-8 and/or TNF, which comprises a porous water-insolube carrier and a compound satisfying the value of log P of at least 2.50, in which P is a distribution coefficient in an octanol-water system and being immobilized onto the carrier, a process for removing the above IL(s) and/or TNF by the adsorbent and an adsorber comprising the adsorbent. According to the present invention, IL(s) and TNF in body fluid can be efficiently absorbed using the above-mentioned adsorbent.
摘要:
A series of novel benzoguanamine derivatives possessing a high anti-peptic ulcer activity with low toxicity has been prepared by the reaction of the corresponding dihalogenobenzonitriles with dicyandiamide or by the reaction of the corresponding carboxylic acids or functional derivatives thereof with biguanide.
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.
