Zusammenfassung:	PCT No. PCT/EP92/01801 Sec. 371 Date Feb. 17, 1994 Sec. 102(e) Date Feb. 17, 1994 PCT Filed Aug. 7, 1992 PCT Pub. No. WO93/03829 PCT Pub. Date Mar. 4, 1993.A dialysis membrane is made of a regenerated cellulose polymer in the form of a hollow fiber with a continuous internal cavity filled essentially with a gas. The hollow fiber has a porous inner and an outer surface. The outer surface of the hollow fiber is formed by a thin skin which has fine lengthwise grooves. The inner surface of the hollow fiber is positively modified by physical and/or chemical means. The invention also includes a method for manufacturing such a dialysis membrane.
