With a simple and high-yield production method, a zinc-containing sustained-release composition capable of stabilizing a physiologically active protein or peptide, typically G-CSF by precipitation and retaining drug efficacy for several days in a living body owing to its sustained releasability is provided. Concretely, a zinc-containing sustained-release composition produced by forming a precipitate by mixing a physiologically active protein or peptide, a water-soluble zinc salt, a water-soluble carbonate and/or a water soluble phosphate aqueous solution. The zinc-containing sustained-release composition may be administered as a zinc-containing sustained preparation by adding a pharmaceutically acceptable additive as is necessary.
摘要:
By a process for preparing halogenated benzene derivatives comprising distilling or stripping a mixture of the isomers of a halogenated benzene derivative containing a hydrogen halide to remove the hydrogen halide from the isomeric mixture of the halogenated benzene derivative and then contacting with a zeolite adsorbent for selectivity separating the desired isomer of the halogenated benzene derivative, it is possible to prevent from degrading the zeolite adsorbent. And it is possible to separate selectively industrially an desired isomer of the halogenated benzene derivative for a long time without reduction of productivity and to separate selectively the desired isomer in high purity.

An image forming apparatus having an image bearing member, a charger to charge the surface of the image bearing member, an irradiator to irradiate the image bearing member to form the latent image, a developing device to develop the latent electrostatic image with toner to obtain a visible image, a transfer device to transfer the visible image to a transfer medium by a transfer bias applied to a transfer area between the image bearing member and the transfer member, and a voltage detector to measure a first surface voltage and a second surface voltage under different conditions, and a life expectancy identification device to identify whether or when the expected working life of the image bearing member has come to the end based on a comparison of the first surface voltage and the second surface voltage.
摘要:
An image carrier deterioration degree evaluating apparatus for evaluating a degree of deterioration of an image carrier of an image forming apparatus, the image carrier deterioration degree evaluating apparatus including: an image deletion detecting unit that detects image deletion by obtaining latent image information written on the image carrier; an image deletion reducing unit that performs a process of reducing image deletion when the image deletion detecting unit detects image deletion, and an image carrier deterioration degree evaluating unit that drives the image deletion detecting unit and the image deletion reducing unit alternately one or more times each, and evaluates a degree of deterioration of the image carrier by using the latent image information obtained one or more times by the image deletion detecting unit.

An isolated protein having the amino terminal sequence of SEQ ID No. 1 and having a molecular weight of about 200 KDa is described. This animal brain-derived protein binds to OSF-1 (HBGF-8), which is a heparin-binding growth factor that has neuronal differentiation-enhancing activity, and a proliferative action on osteoblasts.
摘要:
A specific isomer of dichlorocumene is separated from a mixture containing dichlorocumene isomers by adsorptive separation, wherein the zeolite having at least 2 of silica/alumina molar ratio and 0.6 to 1.0 nm of pore size is used as the adsorbent and halogenated benzene or halogenated alkyl benzene is used as desorbent.
摘要:
A system for securely offixing to a structure at a recess therein comprises a container body filled with a main component and sealed with a cap formed in part by solidifying a hardening agent and an inorganic material with a solidifying agent. The cap may be formed by confining a hardening agent in a film or coated film of plastics. The container body is further subjected to flaw or strain working or otherwise formed to be weakened so as to break into small pieces when subjected to a force by the element. The main component and the hardening agent then react, within the recess, to securely affix the element to the structure. In another aspect of the invention, a method is provided for retaining the first component in its frangible container with a cap comprising the reactive or hardening agent for placement in a recess of the structure for forcible breakage of the container, a reaction and secure affixation by the reaction product.
