  • Patent number: 5306730
    Abstract: A botulinum toxin neutralizer comprising at least one fatty acid having the number of carbon atoms of at least 12. Such a fatty acid may be any of saturated fatty acids such as lauric acid, myristic acid, palmitic acid, stearic acid, nonadecanoic acid, arachidic acid, and behenic acid or any of unsaturated fatty acids such as oleic acid. The toxin neutralizer acts as if it were an antagonistic receptor for botulinum toxin and, when encountering botulinum toxin in human body, directly combines with the toxin and disables the toxin from combining with the neuromuscular tissues of human body to prevent the outbreak of botulism. The toxin thus neutralized and affixed to the botulinum toxin neutralizer is excreted from the human body. The botulinum toxin neutralizer can be manufactured easily and economically from a naturally occurring glyceride and is thus far less costly then the known antitoxin of ganglioside GT1b produced from bovine brain.

  • Patent number: 4771039
    Abstract: A botulinus toxin neutralizer comprising heat-treated fat globule membranes of animal milk or gangliosides isolated from fat globule membranes of animal milk. The neutralizer of the former nature is prepared from a material containing fat globules of animal milk by fractionating the material for separating the membranes of the fat globules from the rest of the material, and subjecting the separated fat globule membranes to heat treatment. The neutralizer of the former nature is prepared from a material containing fat globules by fractionating the material for separating the membranes of the fat globules from the rest of the material, and isolating gangliosides from the globule membranes.
