Effects of Locoweed Intoxication on the Genital Tract of the Ram
American Journal of Veterinary Research, 1971SUMMARY Two purebred yearling rams were fed 454 Gm. of Astragalus lentiginosus (locoweed) for 42 days. At necropsy, there were enlargement of the thyroid gland, parathyroid glands, and seminal vesicles, atrophy of the testes, and a golden tan coloration of the liver and kidneys.

Journal of natural toxins, 1999
Locoweed is the most widespread poisonous plant problem in the western U. S. Eleven species of Astragalus and Oxytropis (and many varieties within these species) cause locoism. Many locoweed species are endemic and are restricted to a narrow niche or habitat.

Limb deformities in foals associated with ingestion of locoweed by mares
Journal of the American Veterinary Medical Association, 1982Summary Five of 26 pregnant mares observed ingesting locoweed (Astragalus mollisimus) subsequently aborted and another 10 produced foals with various limb deformities. Seven of the foals had deformities of a flexion-extension type and 3 had angular deformities. Four foals were normal. The limb deformities either resolved spontaneously (5 cases) or were

Veterinary and human toxicology, 1999
Locoweed (Oxytropis sericea) was fed to 4 open cycling cows that had repeatedly consumed locoweed in previous grazing trails. They received locoweed at 20% of their diet for 30 d (0.68-0.76 mg swainsonine/kg/d). Locoweed induced an immediate rise in serum swainsonine (the locoweed toxin) and a concomitant drop in serum alpha-mannosidase activity in all

Locoweed Poisoning in Sheep: Electroencephalographic and Brain Amine Changes
Clinical Toxicology, 1977The effects in sheep of locoweed poisoning on electroencephalograms and on levels of the brain amines serotonin and norepinephrine were measured. Lucoweed-induced EEG changes in sheep were characterized by episodes of high voltage, slow activity (HVSA). There was no effect on brain norephinephrine levels. The mean brain serotonin level of the sheep fed

Locoweeds of North America: taxonomy and toxicity.
2007AbstractThis chapter describes the taxonomy and toxicity of two locoweeds belonging to the genera Astragalus and Oxytropis, each containing several to numerous species of toxic plant species. Those plants with intoxicant properties have led to numerous livestock deaths, amounting to untold amounts of property loss. The first of those genera, Astragalus,

Fungal Endophytes of Locoweeds: A Commensal Relationship?
Journal of Plant physiology & pathology, 2013Fungal Endophytes of Locoweeds: A Commensal Relationship? The gold standard to ensure correct patient positioning is represented by the maximum surgical exposure and the minimal risk of damage. The aim of this study was to analyze the complications related to patient prone positioning in spinal neurosurgical care from a nursing point of view ...

Quantitative PCR Method To Measure the Fungal Endophyte in Locoweeds
Journal of Agricultural and Food Chemistry, 2009A fungal endophyte ( Undifilum oxytropis ) has been implicated in the synthesis of swainsonine in Oxytropis and Astragalus species, commonly known as locoweeds. A quantitative PCR method has been developed to measure the amount of endophyte in Oxytropis and Astragalus species.
