lathyrus niger/atrophy

Neurolathyrism is associated with a complex pattern of alterations in the glutamatergic system of the cortical motor region of brain. It is a neurological disorder consorted with excessive consumption of Lathyrus sativus (Grass pea), comprising large amounts of the neurotoxin,

We studied the effect of beta-oxalylamino-L-alanine, a glutamate analog present in Lathyrus sativus seeds and implicated in the etiopathogenesis of neurolathyrism, and (+/-)-alpha-amino-3-hydroxy-5-methylisoxazole-4-propionate on the extracellular levels of aspartate, glutamate and taurine in the

BACKGROUND Caley Pea (Lathyrus hirsutus) is potentially toxic to horses, but large case series are not reported. OBJECTIVE To describe the clinical signs of horses intoxicated with Lathyrus hirsutus and speculate on the neuroanatomical lesion localization and pathogenesis based upon the observed

β-N-Oxalyl-l-α,β-diaminopropionic acid (β-ODAP) is a non-protein amino acid present in Lathyrus sativus (grass pea) and other Lathyrus species, in parallel with its nontoxic isomer, α-ODAP. When consuming grass pea for several months as staple food, β-ODAP may cause

Neurolathyrism is a neurodegenerative disease caused by the chronic consumption of Khesari dhal (Lathyrus sativus L). It is generally accepted that beta-N-oxalylamino-l-alanine (b-ODAP), a non-protein amino acid present in the seeds is the primary causative agent. Based on in vitro studies with

Neurolathyrism is a motor neuron disease caused by the overconsumption of grass pea (Lathyrus sativus L.) containing L-β-ODAP. The precise mechanism to cause motor neuron degeneration has yet to be elucidated, but should agree with the epidemiological backgrounds. Considering the amino acid content

We examined the central nervous system of a 67-year-old man who showed symptoms of lathyrism after being imprisoned at age 35 and fed on a diet of chick peas, Lathyrus sativus. The most obvious changes were loss of axons and myelin in the pyramidal tract in the lumbar spinal cord. These alterations

Two hundred patients with chronic neurolathyrism were clinically examined, 25 to 35 years after exposure to the lathyrus sativus pea. All the patients were prisoners in a labour camp under similar nutritional and physical conditions at the outbreak of the syndome. The main symptoms were spastic

Neurolathyrisim is a motor neuron disease characterized by spastic paraparesis in the hind legs, and is caused by grass pea, Lathyrus sativus, which contains the excitotoxic amino acid, 3-N-oxalyl-L: -2,3-diaminopropanoic acid (L: -beta-ODAP), an alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionic

Environmental chemicals involved in the etiology of human neurodegenerative disorders are challenging to identify. Described here is research designed to determine the etiology and molecular pathogenesis of nerve cell degeneration in two little known corticomotoneuronal diseases with established

It has been suggested that beta-N-oxalylamino-L-alanine, a non-protein amino acid present in the Lathyrus Sativus seeds, may play a role in the etiopathogenesis of neurolathyrism, a toxic form of motor neuron disease clinically characterized by a severe spastic paraparesis. In order to investigate

To study the clinical picture of lathyrism in Unnao, India and compare it with that reported from other endemic areas, 41 patients from Unnao were studied. Their mean age was 42.9 years (range 22-85) and the mean duration of the illness was 17.1 years (range 2-30). They had been regularly consuming

β-N-Oxalyl-α,β-diaminopropionic acid (β-ODAP) is a plant metabolite present in Lathyrus sativus (L. Sativus) seeds that is proposed to be responsible for the neurodegenerative disease neurolathyrism. This excitatory amino acid binds to α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA)

Beta-N-oxalylamino-L-alanine (BOAA), a non-protein amino acid present in the seeds of Lathyrus Sativus (LS), is one of several neuroactive glutamate analogs reported to stimulate excitatory receptors and, in high concentrations, cause neuronal degeneration. In the present study, the in vivo acute

Beta-N-methylamino-L-alanine (BMAA) and beta-N-oxalylamino-L-alanine (BOAA) are chemically related amino acids present in the seeds of Cycas circinalis and Lathyrus sativus, respectively. Consumption of these seeds has been linked to Guam amyotrophic lateral sclerosis (BMAA) and lathyrism (BOAA; a
