Title: Agatha Christie 2.0 – Strychnine<br/>Author: Hong Kim<br/><a href='http://umem.org/profiles/faculty/526/'>[Click to email author]</a><hr/><p>
Her first book “The mysterious affair at Styles,” Agatha Christie introduced her lead detective in her novels, Hercule Poirot - the Belgian detective. She also described the death of Mrs. Emily Inglethorp by strychnine.</p>
<p>
Strychnine is found in a disc-like seed of strychnos nux-vomica, a tree native to tropical Asia and North Australia.</p>
<p>
It is currently used as rodenticide (moles and gophers), in Chinese herbal medicine and a traditional remedy in Cambodia.</p>
<p>
Strychnine inhibits binding of glycine (a major inhibitory neurotransmitter in spinal cord) to Cl-channel resulting in identical clinical syndrome – seizure-like generalized muscle contraction with normal mental status – as tetanus toxin. Tetanus toxin inhibits the release of presynaptic glycine in the spinal cord. </p>
