    摘要： Disclosed herein is a high strength austenitic stainless steel with excellent corrosion resistance even in oxidative enviroments, and a method for producing such stainless steel, in which the kinds and proportions of the component elements are strictly restricted, especially limiting the contents of C and N to achieve solution strengthening while preventing degradations in corrosion resistance and defects of steel ingots which would be caused if they are added excessively. Besides, V is added under coexistence with Cr and Ni to increase the strength by precipitation of carbides and nitrides of V while preventing production of Cr carbides.

    摘要： The present invention relates to a method for quantitatively measuring the muscular relaxing activity of a neurotoxin. Specifically, based on an extent of the activity of muscular relaxation of a neurotoxin from bacteria of Clostridium, the present invention relates to a method for quantification of the efficacy (potential and/or diffusion reaction) of a neurotoxin comprising the following steps of: (a) administering a neurotoxin to the hind leg muscle of one of hind legs of a non-human mammal; (b) applying electric stimulus to said non-human mammal; (c) measuring a compound muscle action potential (CMAP) by contraction of said hind leg muscle to which the neurotoxin is administered and/or of the hind leg muscle of the other hind leg to which the neurotoxin is not administered; and (d) taking amplitude data from the compound muscle action potential (CMAP) obtained by the measurement in step (c) and analyzing an extent of a decrease in amplitude to thereby quantify the efficacy of the muscular relaxing activity by the neurotoxin. In contrast to the mouse LD50 currently used as a potential unit of a botulinum toxin which is measurable at a level of only several units, the quantification method of the efficacy of a neurotoxin of the present invention allows for measurement at a level of as low as 0.01 to 1 unit and hence is a method with a high sensitivity, reproducibility and accuracy.

    摘要： A method for quantification of a titer of a neutralizing antibody to a neurotoxin is disclosed. The method comprises the steps: (a) mixing a standard sample containing a fixed amount of a neurotoxin and a test sample containing a neutralizing antibody to said neurotoxin; (b) administering the mixture obtained in step (a) into the muscle of a non-human mammal; (c) applying electric stimulus to said non-human mammal; (d) measuring a compound muscle action potential (CMAP) due to contraction of the muscle of said mammal by application of electric stimulus with an electromyograph; and (e) analyzing CMAP amplitude data obtained in step (d) for an extent of decrease in amplitude by a non-neutralized neurotoxin to thereby quantify a titer of the neutralizing antibody contained in the test sample.
