This satisfies one criterion of a potential chemical warfare agent, although the lack of large scale production of jequirity seeds means that quantity is unavailable for ready mass production of abrin for weapons. Johnson RC, et al.

These seeds are red with a black spot covering one end. Seek medical attention right away. Mercury Inorganic Case Definition: It has a median toxic dose of 0. By attaching to a carbohydrate chain on the cell surface, the abrin molecule anchors itself to the cell, is subsequently engulfed and enters the inner parts of the cell where it reacts with a ribosomal subunit and interferes with the normal protein synthesis process of the cell.

Abrin Jequiritythe source plant of abrin. J Clin Toxicol ; Death from abrin poisoning could take place within 36 to 72 hours of exposure, depending on the route of exposure inhalation, ingestion, or injection and the dose received. Blood purification is an effective measure to eliminate toxicants from the body in acute abrin poisoning. Joe Valentine Wooten, Email: The child appeared to have a normal appetite and activity level through the remainder of the afternoon.


Abrin has a high molecular weight approximately 65 kDa and it is not therefore easily cleared by CRRT. While these tests are sensitive and can provide quantitative results, they require large sample volume, overnight incubation in the case of radioimmunoassay testand more invasive procedures to obtain patient samples [ 211 ].

It is a stable substance and can withstand extreme environmental conditions. A previously healthy month-old, It can also be injected in small pellets and absorbed through contact with the eyes. No widely available, reliable test exists to confirm that a person has been exposed to abrin. Eur J Biochem ; Abrin is a ribosome inhibiting protein like ricina toxin which can be found in the seeds of the castor oil plant [3] and pulchellin, a toxin which can be found in the seeds of the Abrus pulchellus tenuiflorus.

Hemoperfusion is an extracorporeal treatment of filtering the blood to remove toxic metabolites or exogenous toxin based on adsorption, and it is usually used for the treatment of acute poisonings. When masticated rosary peas are ingested, abrin is released into the digestive fluids and absorbed by the body.

In contrast, we measured the urine creatinine level as J Toxicon ; By using this site, you agree to the Terms of Use and Privacy Policy. Excess fluid in the lungs would be diagnosed by x-ray or by listening to the chest with a stethoscope.

Quantification of l -abrine in human and rat abri Small doses absorbed through the eyes can also cause tearing lacrimation. Published by Wolters Kluwer Health, Inc. Using the urine sample creatinine concentration 0. Abrus precatorius poisoning leading to hemorrhagic gastroduodenitis — A rare experience. Colloidal gold-based immunochromatographic test strip for rapid detection of abrin in food samples. If exposure cannot be avoided, the most important factor is then getting the abrin off or out of the body as quickly as possible.

Mechanism of action of toxic lectins abrin and ricin. The conventional treatments including gastric lavage, poisonig, gastric acid suppression by PPI, liver protection, blood volume and electrolytes resuscitation, and hemostasis were performed immediately after admission.

You can put your eyeglasses back on after you wash them. If an exposure to abrin by inhalation is not fatal, the airway can become sensitized or irritated.

During follow-up, no further episodes of emesis were reported after discharge. It cannot be spread from person to person through casual contact.

Ribosome-inactivation tests can accurately determine if clinical samples test positive for the toxin abrin [ 38 ]; however, the test cannot provide a measure of the concentration of abrin in the body which may help in patient management.

Introduction Abrus precatorius is one of the deadliest poisons in the world, known commonly as rosary peas, jequirity bean, and crab’s eye Fig. Before acute liver and kidney injury appear, the combined therapy of CRRT and HP could facilitate toxins clearance and reduce toxins concentration in the body, which will finally prevent exacerbation and reduce mortality.
