Cotyledonary seedlings fed at 0.75% to 3% of body weight or ground bur fed at 20% to 30% of the ration caused acute depression, convulsions, and death. Principle gross lesions were marked serofibrinous ascites, edema of the gallbladder wall, and lobular accentuation of the liver. Acute to subacute centrilobular hepatic necrosis was present microscopically. The previously reported toxic principle, hydroquinone, was not recovered from the plant or bur of X. strumarium. Authentic hydroquinone administered orally failed to produce lesions typical of cocklebur intoxication but did produce marked hyperglycemia. Carboxyatractyloside recovered from the aqueous extract of X. strumarium and authentic carboxyatractyloside, when fed to pigs, caused signs and lesions typical of cocklebur intoxication. Marked hypoglycemia and elevated serum glutamic oxaloacetic transaminase and serum isocitric dehydrogenase concentrations occurred in pigs with acute hepatic necrosis that had received either cocklebur seedlings, ground bur or carboxyatractyloside.<\/jats:p>","DOI":"10.1177\/030098588101800310","type":"journal-article","created":{"date-parts":[[2017,1,16]],"date-time":"2017-01-16T03:05:39Z","timestamp":1484535939000},"page":"368-383","source":"Crossref","is-referenced-by-count":56,"title":["Cocklebur (\n                    <i>Xanthium strumarium<\/i>\n                    , L. var.\n                    <i>strumarium<\/i>\n                    ) Intoxication in Swine: Review and Redefinition of the Toxic Principle"],"prefix":"10.1177","volume":"18","author":[{"given":"B.
