Butyl acrylate is of low acute toxicity with an LD 50 (rat) of 3143 mg/kg. [ 4 ] In rodent models, butyl acrylate is metabolized by carboxylesterase or reactions with glutathione ; this detoxification produces acrylic acid , butanol , and mercapturic acid waste, which are excreted.
Several plants, including nightshade, become more toxic as they wilt and die, posing a danger to horses eating dried hay or plant matter blown into their pastures. [ 3 ] The risk of animals becoming ill during the fall is increased, as many plants slow their growth in preparation for winter, and equines begin to browse on the remaining plants.
Nigropallidal encephalomalacia or Chewing disease is a neurological condition that affects horses that have eaten certain toxic plants. Affected animals are unable to prehend food because of lip and tongue paralysis, and may appear to keep their jaws open with the tongue protruded because of reduced jaw tone. [ 1 ]
Recurrent airway obstruction, also known as broken wind, heaves, wind-broke horse, or sometimes by the term usually reserved for humans, chronic obstructive pulmonary disease or disorder (COPD) – it is a respiratory disease or chronic condition of horses involving an allergic bronchitis characterised by wheezing, coughing and laboured breathing.
A horse may be returned to work if symptoms have ceased and is no longer on NSAIDs or other prescribed drugs related to treatment of ER, this can otherwise can hide signs of another bout of ER. If NSAIDs or other treatment drugs are needed to keep the horse comfortable, or if the horse is reluctant to continue work, the animal is not yet ready ...
Carbamate poisoning is poisoning due to exposure to carbamates, which are commonly sold as pesticides around the world. In most respects, it is similar to organophosphate poisoning , though typically less severe or requiring a larger amount of the chemical before symptoms appear.
The database has three objectives: 1) to identify the frequency, type, and outcome of horse racing injuries using a standardized format that will generate valid composite statistics; 2) identify markers for horses at increased risk of injury; and 3) to serve as a data source for research directed at improving safety and preventing injuries.

Some taxine alkaloids have been isolated to study their effects and characteristics. This has allowed the discovery of some of the particular effects of each substance of the plant. For example, taxine A does not influence blood pressure, taxol causes cardiac disturbances in some people, that taxine B is the most toxic of these substances. [41]
