Ricin is a powerful protein toxin found in the castor plant, ricinus communis ricin is very toxic by several routes of exposure, including inhalation, ingestion and injection most natural exposures occur by ingestion in mice, this is the least. The poison can kill within three days of exposure even a small amount of ricin may be fatal no widely available, reliable test exists to confirm exposure to ricin there's no vaccine or antidote for ricin poisoning treatment is primarily supportive care. Antibody treatment at 12 h post-ricin exposure resulted in the survival of only one of five monkeys, signifying that, in the majority of animals, ricin intoxication and local tissue damage had progressed beyond the point where hupb10 intervention was beneficial. After exposure, the two antibodies, administered up to 6 hours after toxin challenge, were each capable of rescuing mice from toxin-induced death, suggesting that gd12 might have both prophylactic and therapeutic potential for ricin intoxication.

Accidental exposure to ricin is rare and results primarily from the ingestion of castor seeds ricin toxicity purified ricin occurs in the form of a soluble white powder that is extracted from castor seeds or from the waste materials generated during the production of castor oil. Repeated exposure in humans is known to cause allergic/asthma-like symptoms including congestion of the nose and throat, itchyness of the eyes, hives, tightness of the chest, and in severe cases, wheezing. Until recently, there wasn’t a way to test human samples for ricin exposure doctors could only track the symptoms –fever, cough, difficulty breathing, organ failure, and check for fluid build-up in a patient’s lungs.

Ricin is a potential bioweapon that could be used against civilian and military personnel aerosol exposure is the most likely route of contact to ricin toxin that will result in the most severe toxicity early recognition of ricin exposure is essential if specific antidotes are to be applied. Abstract ricin intoxication is a fatal and an uncommon medical condition we report a case of ricin poisoning in a 42-year-old saudi male patient who ingested a herbal medicine mixture containing ricin bean powder, after which he presented with gastrointestinal symptoms followed by gastrointestinal bleeding and hypotension.
Ricin poisoning symptoms can lead to death within five days after the toxin is inhaled— though it's not contagious, the substance is regarded a class b bioterrorism agent by the cdc. Ricin is a highly toxic, bi-chain polypeptide which can be extracted from the castor bean, ricinus communis toxicity may arise from ingestion of either the seed itself or through ingestion, inhalation or injection of the extracted protein. Routes of exposure: ricin can be absorbed into the body through ingestion, inhalation, or eye contact ricin can be absorbed through abraded skin or through wounds, but probably not through intact skin, unless it is carried in a solvent that enhances absorption ricin can also be transmitted through the skin via small pellets or projectiles.
Ricin is a poison found naturally in castor beans if castor beans are chewed and swallowed, the released ricin can cause injury ricin can be made from the waste material left over from processing castor beans it can be made in the form of a powder, a mist, or a pellet, or it can be dissolved in. Ricin exposure by ingestion (swallowing) typically results in symptoms in less than six hours following exposure symptoms include vomiting and diarrhea that may contain blood, possibly resulting in dehydration severe enough to cause low blood pressure , and blood in the urine. Ricin is a potent toxin extracted from castor beans there is a lot of fear and misinformation associated with this poison the purpose of this fact sheet is to help separate fact from fiction regarding ricin poisoning.

Ricin is a protein derived from the beans of the castor plant (r communis)castor beans are used in the production of castor oil, a brake and hydraulic fluid constituent. Ricin toxin, a water-soluble glycoprotein that does not partition into the oil extract, is a ribosome-inactivating toxin composed of two chains, labeled a and b severity of the toxicity varies depending on the route of exposure to the toxin. Ricin is an extremely toxic natural poison made from castor beans it kills cells by preventing them from making proteins needed to survive effects from exposure typically show up within a day.
