Molluscicidal activity of Abrus precatorius linn. DESCRIPTION: Abrin is an extremely toxic plant protein derived from the seeds of the plant Abrus precatorius. Abrins a through d (mol wt 63,000-67,000 Da) are composed of two disulfide-linked polypeptide chains. Abrin was extracted from Semen jequiriti and purified by chromatography on a DEAE‐cellulose column and on a Sepharose‐4B column.
Seizures are reported more frequently in animals than in people (,Ricin is among the most toxic compounds known when given parenterally. DESCRIPTION: Abrin is an extremely toxic plant protein derived from the seeds of the plant Abrus precatorius. Both enzyme activities of the 8-S complex were inhibited by abrin and ricin. Abrus agglutinin is a tetramer of 134,900 Da, is non-toxic to animal cells and a potent hemagglutinator.
1977 Apr 25;75(4):845-50. doi: 10.1016/0006-291x(77)91459-0.Mol Biol (Mosk). 2013 Jul 29;8(7):e70273. If the seed coat is injured or destroyed (by chewing, for example) the toxin may be released.Chemically, abrin is a mixture of four isotoxins, these being abrin a, b, c, and d. Occasionally, the non-toxic hemagglutinin of,Abrin-a is the most potent of the four isotoxins, encoded for by an intron-free.Abrin is not known to have been weaponised,Abrin naturally occurs in the seeds of the.Although there is no consensus on the level of lethal dose in humans after oral intake, it is assumed that the intake of 0.1 to 1 microgram per kilogram of body weight, or the consumption of a single seed of the rosary pea, may be fatal, but this information is not sufficiently documented.Abrin is significantly more toxic following intravenous administration. If cough or dyspnea develops, administer supplemental oxygen. Abrin is only formed in nature by the rosary pea. Following ingestion of abrin, initial symptoms usually occur rapidly, but can take up to five days to appear.The later signs and symptoms of exposure are caused by abrin's cytotoxic effects, killing cells in the kidney, liver, adrenal glands, and central nervous system.Within a few hours of inhaling abrin, common symptoms include fever, cough, airway irritation,Swallowing any amount of abrin can lead to severe symptoms. Kinetics of the enzymic activity of the toxin A-chains.Correlation of inhibition of ribosomal GTPase and protein synthesis by abrin and ricin.
If hematuria is present, consider alkalinization of the urine. Other treatments are the same as for an oral exposure.There are no controlled studies demonstrating that animals are more susceptible to developing acute effects than humans.We use cookies to help provide and enhance our service and tailor content and ads.
