Botox

In this time, Botox was used by many woman in this world. What is Botox? Botulin toxin or botox is the toxic compound produced by the bacterium Clostridium botulinum. It is an enzyme that breaks down one of the fusion proteins that allow neurons to release acetylcholine at a neuromuscular junction. By interfering with nerve impulses in this way, it causes paralysis of muscles in botulism. The toxin itself is a two-chain polypeptide with a 100 kDa heavy chain joined by a disulphide bond to a 50-kD light chain. It is possibly the most toxic substance known, with a lethal dose of about 300 pg/kg, meaning that somewhat over a hundred grams could kill every human living on the earth.

Botulin toxin is used (usually under a trademarked name such as "Botox") for producing long-term (months) paralysis of muscles. This was intended for the relief of uncontrollable muscle spasms, but is increasingly being used for cosmetic purposes, to paralyse facial muscles as a means of concealing wrinkles.

Botulin toxin has always been considered an ideal agent for chemical warfare (though, given its origins, the distinction from biological warfare is a thin one), since it oxidises rapidly on exposure to air, so an area attacked with a toxin aerosol would be safe to enter within a day or so. There are no documented cases of the toxin actually being used in warfare. There has been concern over the use of botulin toxin as a terrorist weapon, but it appears to not be ideal for this purpose. The vials of toxin used therapeutically are considered impractical for use by terrorists because each vial has only an extremely small fraction of the lethal dose for humans.

The toxin's properties did not escape the attention of the Aum Supreme Truth cult in Japan, who actually set up a plant for bulk production of this agent, though their terrorist and assassination attacks used the nerve agent sarin instead, it being easier to disperse and faster acting.

The CIA once prepared some cigars of Fidel Castro's favorite brand which had been saturated with botulinum toxin, against the possibility of an assassination attempt. The cigars were never used, but when tested years later were still found to be effective. Botox is also used as a treatment against hyperhydrosis (excessive sweating).
