Abstract: A novel type A botulinum toxin preparation is provided. A neuromuscular transmission blocking agent comprising as an active ingredient a highly purified type A botulinum toxin from Clostridium botulinum as infant botulism pathogen and a medicament for treating a disease with a muscle overactivity comprising as an active ingredient said toxin. In particular, the medicament of the present invention, as compared to the conventional known botulinum toxin preparations, has rapid efficacy of potential and is less diffusive and thus, having a broader safety margin, may be used as therapeutic medicament for decreasing local, muscle overactivity in a disease with a muscle overactivity.

Abstract: The present invention relates to a method for quantitatively measuring the muscular relaxing activity of a neurotoxin.

Abstract: Problem: An object of the present invention is to provide a drug effective for the treatment of ALS, or a method for treating ALS. Solution: The present invention provides an ALS treatment method that improves clinical symptoms of ALS or suppresses the progression of ALS by administering an anti-TNFalfa monoclonal antibody to an ALS patient; an anti-ALS drug containing an anti-TNFalfa monoclonal antibody; an anti-TNFalfa monoclonal antibody for use as an anti-ALS drug; and use of an anti-TNFalfa monoclonal antibody for the treatment of ALS and for the manufacture of a medicament.

Abstract: The present invention relates to a method for quantitatively measuring the muscular relaxing activity of a neurotoxin.

Abstract: 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.

Abstract: A remedy for muscle hyperactivity, comprising a purified botulinum neurotoxin as an active ingredient.

Abstract: A method for treating amyotrophic lateral sclerosis (ALS) and a therapeutic agent therefor are provided. The therapeutic agent comprising ultra-high doses of methylcobalamin (for example, from about 15 mg to about 500 mg per day) is administered to a patient with ALS intramuscularly, subcutaneously or intravenously for from about a week to about 2 years to ameliorate or improve both the clinical symptoms and an objective clinical measure in ALS or retard the muscle weakness caused by ALS.
