Bean common mosaic necrosis virus (BCMNV) is a plant pathogenic virus that can infect leguminous crops such as kidney beans, sunn hemp, red beans, and mung beans. BCMNV has not been reported in Korea and is classified as a quarantine plant virus. Currently, the standard diagnostic method for
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
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
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
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
BACKGROUND
Crotalaria species have been widely used in Chinese traditional medicine to treat several types of internal cancers. Crotalaria agatiflora is used as a medicinal plant in several African countries for the treatment of bacterial and viral infections as well as for cancer.
METHODS
Water and
In South Africa traditional medicine plays an important role in primary health care and therefore it is very important that the medicinal use of plants is scientifically tested for toxicity and effectiveness. It was established that the ethanolic extract of the leaves of Crotalaria agatiflora, as
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,
The effect of the ethanolic extract of Crotalaria juncea Linn. (Leguminosae) seeds has been assessed on liver, kidney, spleen and adrenals of adult rats. Results revealed that its administration at a dose of 200 mg/kg caused significant alterations. Wet weight of the organs was reduced. Protein and
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
Acute intoxication by seeding Crotalaria retusa occurred during the dry season, in a flock of 80 sheep, in the semi-arid region of the state of Paraiba, northeastern Brazil. Anorexia, severe depression, mild jaundice, incoordination and recumbence were observed in 16 sheep that died within 12 h. At
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
There is a paucity of data on the occurrence of hepatotoxic and hepatocarcinogenic pyrrolizidine alkaloids in medicinal plants, and there are no data on the hepatotoxic properties of herbal medicines that are used in the traditional pharmacopoiea of Sri Lanka and other Asian and African countries.
