Abstract: Methods, compositions and systems for preventing an adverse reaction of the skin to the presence of a skin-sensitizing and/or skin-irritating agent by administering an effective amount of phenoxyacetic acid and/or a lower alkyl ester thereof to a warm blooded animal.
Abstract: An apparatus is provided for centrifuging and further automatically handling a container (110) for separating a component, such as fibrin monomer, from blood. The container (110) comprises a cylindrical member (27) and a piston displaceable in said cylindrical member, said piston comprising a tubular piston rod (8) extending through a top wall (73). The piston divides the cylindrical member (27) into a first chamber (70) positioned above said piston between said piston and the top wall (73), and a second chamber positioned below said piston. The top wall (73) of the container comprises an extension (90) defining a circumferential slit surrounding the outer side of the piston rod (8), whereby one end of said slit communicates in the axial direction with the first chamber. In addition, the first chamber communicates through a plurality of channels with the second chamber.
