crotalaria pallida/섬유화

Monocrotaline (MCT), a pyrrolizidine alkaloid extracted from the shrub Crotalaria spectabilis, induces in the lungs of many mammalian species severe hypertension and fibrosis. Previous work with MCT-induced lung disease in rats has shown that some of the steps to progressive fibrosis can be

Since 1984, a significant number of privately owned and feral horses on Easter Island have died of a syndrome consisting of progressive anorexia, weight loss, obtundation, and other central nervous system abnormalities. A single horse experiencing clinical signs of the reported syndrome was

Ten Nubian goats were given daily oral doses ranging from 0.5 to 10 g/kg/day of the fresh shoots of Crotalaria saltiana; they died at various times after dosing. The main signs of Crotalaria poisoning were dullness, dyspnea, inappetence, loss of condition and arching of the back. An increase in the

Monocrotaline, a pyrrolizidine alkaloid derived from Crotalaria spectabilis, is known to be toxic to a variety of domestic and laboratory animals and to humans. Major pathological effects induced by monocrotaline poisoning include hepatic cirrhosis and megalocytosis, venocclusive disease, pulmonary

Five groups of 30 male Japanese quail, each 7-w-old, were fed diets containing 0, 1, 3, 5, or 10% (w/w) of dehulled H dolosum seed. Half of the birds from the each group were killed at 6 and 24 w after beginning of the trial. At the end of 6th w, neither mortality nor clinical sign occurred in test

The effects and susceptibility of donkeys to Crotalaria juncea and Crotalaria retusa poisoning were determined at high and low doses. Seeds of C. juncea containing 0.074% of dehydropyrrolizidine alkaloids (DHPAs) (isohemijunceines 0.05%, trichodesmine 0.016%, and junceine 0.008%) were administered

Seeds of Crotalaria retusa containing 6.84% (dry weight) of monocrotaline (MCT) were administered experimentally to sheep. Three sheep that received 136.8mg MCT/kg bw daily for 70 days had no clinical signs. Five out of six sheep ingesting single doses of 205.2 and 273.6mg MCT/kg bw died with acute

Twenty-eight horses in southern Mozambique died after exhibiting severe respiratory distress. At necropsy, the overinflated lungs did not collapse, had prominent rib impressions, and were fibrotic and emphysematous. Microscopically, prominent proliferation of nonciliated epithelial (Clara) cells in
