Fibrinoid necrosis was induced in the pulmonary arteries of five male Wistar albino rats by feeding them on a diet adulterated by the addition of 0.07% ground Crotalaria spectabilis seeds by weight. Electron microscopy of the arteries affected by the process showed fibrin in the thrombus occluding
Protective effect of beraprost sodium, a stable prostacyclin analogue, in development of monocrotaline-induced pulmonary hypertension.

Experimental pulmonary hypertension (PH) was induced by a single injection of monocrotaline (MCT), a pyrrolizidine alkaloid extracted from Crotalaria spectabilis. The effect of beraprost sodium, a stable prostacyclin analogue, on the development of MCT-induced PH in rats was studied. Chronic

Crotalaria retusa L. (rattleweed), estimated to contain about 4.96% monocrotaline (MCT) in the seed, was associated with a natural poisoning outbreak in goats. The poisoning was experimentally reproduced by the administration of C. retusa seeds containing approximately 4.49% of MCT. Thus, 1 of 3

The oral LD50 of Crotalaria assamica, which contains mainly monocrotaline, was found to be 154 mg/kg in mice. Neither liver necrosis nor morbidity was demonstrated with Eupatorium extract at a dose level of 144 mg/kg, which was equivalent to the LD20 of Crotalaria. Pretreatment with phenobarbitone

Dry Crotalaria saltiana shoots were fed to strain ASL mice at 50, 10 and 1% of the diet. Feeding of Crotalaria shoots at 50 and 10% produced toxicity and death after 7 to 29 days. The signs of Crotalaria poisoning were inappetence, dullness, dyspnea and recumbency. The main lesions were necrosis,

Monocrotaline, an alkaloid obtained from Crotalaria spectabilis, provides an experimental model for studies of mesangiolysis as seen in Habu venom poisoning and hemolytic-uremic syndrome. Renal lesions induced in rats by a single intraperitoneal administration of monocrotaline were examined by light

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
