Pulmonary hypertension produced in rats by ingestion of Crotalaria spectabilis seeds.
Young rats fed on a diet which contains Crotalaria spectabilis seeds or the pyrrolizidine alkaloid monocrotaline die from congestive heart failure within 36 to 60 days. At necropsy they are found to have ascites, pleural effusions, and cardiac enlargement due to right ventricular hypertrophy (Turner and Lalich, 1965; Kay and Heath, 1966). Microscopic examination reveals an increase in the media...
متن کاملThe electron microscopy of "fibrinoid necrosis" in pulmonary arteries.

Electron microscopy of the arteries affected by the process showed fibrin in the thrombus occluding their lumens and in the arterial intima, held up from further penetration of the media by the inne...

The endothelial cell in each of the four blood vessels was found to have its own distinctive shape, fusiform and pointed in the direction of blood flow in the case of the aorta and larger and more rectan...
متن کاملFulvine and the pulmonary circulation.
The pyrrolizidine alkaloid, fulvine, is now accepted as a major cause of veno-occlusive disease of the liver in the West Indies, where it is ingested as a decoction of the plant Crotalaria fulva in bush tea. Fulvine is similar in chemical structure to monocrotaline, which is known to cause pulmonary hypertension in rats. Thirty young female rats were given a single dose of fulvine either by int...
