senecio jacobaea/atrophy

Eight 1-year-old Romney-Marsh female sheep were used to test the effect of Senecio erraticus (ragwort). Animals were fed for 60 days on a standard diet incorporating 20% dried ground ragwort. Morphology of the livers was studied by serial biopsy and function by changes in plasma bilirubin

Ventricular fibrillation (VF) has been classified electrocardiographically as "fine amplitude" or "coarse amplitude" VF. It has been suggested that coarse VF represents increased "synchronization" of myocardial activation which could result in lower thresholds for defibrillation. To test the

Epidemiological, clinical, necropsy and histopathological data were accumulated during the study of 15 outbreaks of Senecio spp poisoning in cattle occurring during the last 3 y in the State of Rio Grande do Sul, Brazil. Morbidity averaged 17% and mortality was virtually 100%. The peak mortality

The enzyme homospermidine synthase catalyzes the NAD+-dependent conversion of 2 mol putrescine into homospermidine. Instead of putrescine, spermidine can substitute for the first putrescine moiety in plants, in which case diaminopropane instead of ammonia is released. The enzyme facilitates the

Twenty horses of various ages had inadvertently ingested alfalfa hay contaminated with Senecio vulgaris. Among them, 4 died of liver disease. Blood was collected from affected horses at monthly intervals for 7 months and at the 9th and 14th months. The following serum enzymes and chemical items were

Controlled clinically relevant animal models are essential in the ongoing search for increasingly cost-effective methods to reverse clinical death. Acute (up to 12 h) and short-term (up to 24 h) experiments are useful for the study of dying mechanisms and restoration of spontaneous circulation.
