The effect of methionine on the uptake, distribution, and binding of the convulsant methionine sulfoximine in the rat

The effect of methionine on the uptake, distribution, and binding of the convulsant methionine sulfoximine (MSO) in 7 rat brain regions, the spinal cord, the liver, and the kidney was investigated. The administration of methionine decreased the uptake of MSO in all brain regions. The uptake of MSO by and its distribution in the nervous tissue was uniform and failed to result in any preferential accumulation of the drug. Methionine decreased the amount of MSO bound to cerebral structures and to the spinal cord. MSO bound to the spinal cord was less susceptible to release by Triton X-100 than was brain-bound MSO.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/45398/1/11064_2004_Article_BF00965631.pd

Lessons from neurolathyrism: A disease of the past & the future of Lathyrus sativus (Khesari dal)

Neurolathyrism is past history in India since Lathyrus sativus (khesari dal) is no longer used as a staple. A consensus has evolved that khesari dal is harmless as part of a normal diet. L-ODAP (β-N-oxalyl-l-α-diamino propionic acid) the neurotoxic amino acid, from this pulse, is detoxified in humans but not in animals but still no laboratory animal is susceptible to it under acceptable feeding regimens. L-ODAP is an activator of protein kinase C and consequential crucial downstream effects such as stabilization of hypoxia inducible factor-1 (HIF-1) could be extremely conducive to humans under a variety of situations. ODAP is gradually finding a place in several patents for this reason. Homoarginine the second amino acid from L. sativus can be a better substrate for endogenous generation of nitric oxide, a crucial signaling molecule associated with the cardiovasculature and control of hypertension. These features could make L. sativus a prized commodity as a functional food for the general cardiovasculature and overcome hypoxic events and is set to change the entire perception of this pulse and neurolathyrism
