Why Does It Work?
The biological reason electroshock treatment neutralizes the incompatible alien proteins of snake venom remains unclear. Besides proteins, snake venom contains enzymes and trace elements that could easily be uncoupled or ionized by high-voltage electricity. In the British medical journal, The Lancet (Dec. 6, 1986), C. Kroege and K H. Meyer propose the theory that electricity may neutralize the snake venom by destroying the secondary and tertiary structures of enzymes by influencing their hydrogen bonds.
High voltage electricity may also reduce metal ions that are attached to harmful enzymes, thus making these enzymes no longer destructive. Also since body tissue is negatively charged and snake venom is positively charged, unlike charges attract. With the application of electricity, venom may become negatively charged, thus negating its magnetic attraction to body tissue.
Excellent information!
All I remember was that the shock was thought to break some of the bonds on the long-chain protein molecules which make up most venoms.
Cheap insurance when you are in snake country.
Too bad none of the bureaucrats had the good sense to handle it in a productive way.
