Abstract: A device for reducing the number of leucocytes in blood comprising a plurality of hollow fibers based on organic polymers, whereby the hollow fibers have a lumen and a wall surrounding the lumen, said wall having an internal surface facing the lumen and an external surface, whereby the hollow fibers are arranged in a cylindrical housing with an inlet arrangement and an outlet arrangement and whereby an outer space is formed between the hollow fibers and the housing, which space is accessible for a fluid via the inlet arrangement and the outlet arrangement, characterized in that only the external surfaces of the hollow fibers are accessible for a fluid, that the lumina of the hollow fibers are not accessible for a fluid, that the arrangement of the hollow fibers shows a high degree of order and that the hollow fibers based on organic polymers cause a generation of the complement activation product C5a in a concentration of at least 10 ?g per m2 of fiber surface.

Abstract: A ball-and-socket joint for a motor vehicle, and especially for the chassis of the motor vehicle, with a ball-and-socket joint housing is provided with a joint opening (6), in which housing there is arranged a bearing shell (5). The ball-and-socket joint has a ball pivot (3) with a pin (2) and with a joint ball (1), which is rotatably and pivotably mounted in the bearing shell (5), in which case the pin extends out of the ball-and-socket joint housing (4) through the bearing shell (5) and the joint opening (6). The bearing shell (5) is made at least partially of a plastic mixed with an anti-adhesive material and reinforced with fibers.
