Chronic uremic patients undergoing periodical dialysis are treated with carnitine or one of its salts to prevent or treat carnitine deficiency in patients with end stage renal disease. In one embodiment, the multipath processing architecture is implemented as part of a packet classification engine of a network node. Therefore, since the method and apparatus encode and decode image data in one-dimensional block units, real-time encoding and decoding can be achieved. Moreover, a digital outputting unit 25 outputs an uncompressed video signal, and therefore can provide a preferable video signal without deteriorating the effective picture elements of an imaging element. When the disposable product package is empty, the disposable product package and the pump if disposable are removed from the dispensing station and disposed. The above-mentioned object of the present invention can be achieved by providing an alignment-layer-attached film for optical element use, comprising: a long transparent base material; and an alignment layer formed on the transparent base material, wherein the alignment layer comprising a resin having a concavo-convex shape to align liquid crystals.
