Slaframine
Slaframine is an indolizidine alkaloidal mycotoxin that generally causes salivation (slobbers) in most animals. It is usually produced by the fungus ''Rhizoctonia leguminicola''. It is a common fungal pathogen of red clover ('' Trifolium pratense'') that causes black patch disease in the plant. Slaframine has the molecular formula C10H18N2O2.Smith G. W., (2007). Slaframine. In R.C.Gupta (Eds.), ''Veterinary Toxicology: Basic & Clinical Principles'', Chapter 81, pp. 1011-1013 The different environmental condition promotes the growth of the Rhizoctonia leguminicola fungus. For example, wet and humid weather are the favorable environmental condition for the growth of the fungus and production of slaframine. Legume hays contaminated with slaframine causes slobber syndrome and the various animals are sensitive to its effects.Gaskill C., (2010). Slaframine Toxication. ''Bluegrass Equine Digest''.

Rhizoctonia Leguminicola
''Slafractonia leguminicola'' (formerly ''Rhizoctonia leguminicola'') is a fungus that is a plant pathogen that most often attaches itself to the '' Trifolium pratense'' or red clover. It is also called black patch disease. The infection is first seen as small black patches on the leaves of red clover (often on the bottom of the leaves first) and spreads to cover the entire plant, killing it. The hyphae of this fungus are white and web-like in appearance, just like those of other fungi. The consumption of the fungus can be harmful to any grazing animals, especially to horses and cows. Effects of consumption If ''Slafractonia leguminicola'' is consumed excessively by horses or cattle, the most noticeable symptom will be an increase in salivation ( drool). Other symptoms include "eye discharge, bloat, frequent urination, watery diarrhea, reduced milk production, weight loss and abortion." Granted, the consumption must be exorbitant to cause these symptoms of such large an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alkaloids
Alkaloids are a class of basic, naturally occurring organic compounds that contain at least one nitrogen atom. This group also includes some related compounds with neutral and even weakly acidic properties. Some synthetic compounds of similar structure may also be termed alkaloids. In addition to carbon, hydrogen and nitrogen, alkaloids may also contain oxygen, sulfur and, more rarely, other elements such as chlorine, bromine, and phosphorus.Chemical Encyclopedia: alkaloids xumuk.ru Alkaloids are produced by a large variety of organisms including , , |
Atropine
Atropine is a tropane alkaloid and anticholinergic medication used to treat certain types of nerve agent and pesticide poisonings as well as some types of slow heart rate, and to decrease saliva production during surgery. It is typically given intravenously or by injection into a muscle. Eye drops are also available which are used to treat uveitis and early amblyopia. The intravenous solution usually begins working within a minute and lasts half an hour to an hour. Large doses may be required to treat some poisonings. Common side effects include a dry mouth, large pupils, urinary retention, constipation, and a fast heart rate. It should generally not be used in people with angle closure glaucoma. While there is no evidence that its use during pregnancy causes birth defects, that has not been well studied. It is likely safe during breastfeeding. It is an antimuscarinic (a type of anticholinergic) that works by inhibiting the parasympathetic nervous system. Atrop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blood Plasma
Blood plasma is a light amber-colored liquid component of blood in which blood cells are absent, but contains proteins and other constituents of whole blood in suspension. It makes up about 55% of the body's total blood volume. It is the intravascular part of extracellular fluid (all body fluid outside cells). It is mostly water (up to 95% by volume), and contains important dissolved proteins (6–8%; e.g., serum albumins, globulins, and fibrinogen), glucose, clotting factors, electrolytes (, , , , , etc.), hormones, carbon dioxide (plasma being the main medium for excretory product transportation), and oxygen. It plays a vital role in an intravascular osmotic effect that keeps electrolyte concentration balanced and protects the body from infection and other blood-related disorders. Blood plasma is separated from the blood by spinning a vessel of fresh blood containing an anticoagulant in a centrifuge until the blood cells fall to the bottom of the tube. The bloo ...

Cyanosis
Cyanosis is the change of body tissue color to a bluish-purple hue as a result of having decreased amounts of oxygen bound to the hemoglobin in the red blood cells of the capillary bed. Body tissues that show cyanosis are usually in locations where the skin is thinner, including the mucous membranes, lips, nail beds, and ear lobes. Some medications containing amiodarone or silver, Mongolian spots, large birth marks, and the consumption of food products with blue or purple dyes can also result in the bluish skin tissue discoloration and may be mistaken for cyanosis. Cyanosis is further classified into central cyanosis vs. peripheral cyanosis. Pathophysiology The mechanism behind cyanosis is different depending on whether it is central or peripheral. Central cyanosis Central cyanosis is caused by a decrease in arterial oxygen saturation (SaO2) and begins to show once the concentration of deoxyhemoglobin in the blood reaches a concentration of ≥ 5.0 g/dL (≥ 3.1 mmol/L ...

Dose (biochemistry)
A dose is a measured quantity of a medicine, nutrient, or pathogen which is delivered as a unit. The greater the quantity delivered, the larger the dose. Doses are most commonly measured for compounds in medicine. The term is usually applied to the quantity of a drug or other agent administered for therapeutic purposes, but may be used to describe any case where a substance is introduced to the body. In nutrition, the term is usually applied to how much of a specific nutrient is in a person's diet or in a particular food, meal, or dietary supplement. For bacterial or viral agents, dose typically refers to the amount of the pathogen required to infect a host. For information on dosage of toxic substances, see Toxicology. For information on excessive intake of pharmaceutical agents, see Drug overdose. In clinical pharmacology, dose refers to dosage or amount of dose administered to a person, whereas exposure means the time-dependent concentration (often in the circulatory blood ...

Forage
Forage is a plant material (mainly plant leaves and stems) eaten by grazing livestock. Historically, the term ''forage'' has meant only plants eaten by the animals directly as pasture, crop residue, or immature cereal crops, but it is also used more loosely to include similar plants cut for fodder and carried to the animals, especially as hay or silage. While the term ''forage'' has a broad definition, the term ''forage crop'' is used to define crops, annual or biennial, which are grown to be utilized by grazing or harvesting as a whole crop. Common forages Grasses Grass forages include: *'' Agrostis'' spp. – bentgrasses **'' Agrostis capillaris'' – common bentgrass **''Agrostis stolonifera'' – creeping bentgrass *'' Andropogon hallii'' – sand bluestem *''Arrhenatherum elatius'' – false oat-grass *''Bothriochloa bladhii'' – Australian bluestem *'' Bothriochloa pertusa'' – hurricane grass *'' Brachiaria decumbens'' – Surinam grass *'' Brachiaria humidi ...

Diarrhea
Diarrhea, also spelled diarrhoea, is the condition of having at least three loose, liquid, or watery bowel movements each day. It often lasts for a few days and can result in dehydration due to fluid loss. Signs of dehydration often begin with loss of the normal stretchiness of the skin and irritable behaviour. This can progress to decreased urination, loss of skin color, a fast heart rate, and a decrease in responsiveness as it becomes more severe. Loose but non-watery stools in babies who are exclusively breastfed, however, are normal. The most common cause is an infection of the intestines due to either a virus, bacterium, or parasite—a condition also known as gastroenteritis. These infections are often acquired from food or water that has been contaminated by feces, or directly from another person who is infected. The three types of diarrhea are: short duration watery diarrhea, short duration bloody diarrhea, and persistent diarrhea (lasting more than two wee ...

Bloating
Abdominal bloating (or simply bloating) is a short-term disease that affects the gastrointestinal tract. Bloating is generally characterized by an excess buildup of gas, air or fluids in the stomach. A person may have feelings of tightness, pressure or fullness in the stomach; it may or may not be accompanied by a visibly distended abdomen. Bloating can affect anyone of any age range and is usually self-diagnosed, in most cases does not require serious medical attention or treatment. Although this term is usually used interchangeably with abdominal distension, these symptoms probably have different pathophysiological processes, which are not fully understood. The first step for the management is to find a treatment for the underlying causes that produce it through a detailed medical history and a physical examination. The discomfort can be alleviated by the use of certain drugs and dietary modifications. Bloating can also be caused by chronic conditions and in rare cases can be a ...

A ..., odd-toed ungulate, one-toed, ungulate, hoofed mammal. It belongs to the taxonomic family Equidae and is one of two Extant taxon, extant subspecies of wild horse, ''Equus ferus''. The horse has evolution of the horse, evolved over the past 45 to 55 million years from a small multi-toed creature, ''Eohippus'', into the large, single-toed animal of today. Humans began domesticating horses around 4000 BCE, and their domestication of the horse, domestication is believed to have been widespread by 3000 BCE. Horses in the subspecies ''caballus'' are domesticated, although some domesticated populations live in the wild as feral horses. These feral populations are not true wild h ...
