Taurine: an essential nutrient for cats 总被引：1，自引：0，他引：1

The β-sulphonic amino acid taurine is synthe-sised in animals from dietary sulphur amino acids. Cats exclusively use taurine to conjugate cholic acid rather than being able to use the alternate glycine conjugation. Since total body synthesis of taurine in cats is limiting, metabolic deficiencies of taurine occur when the dietary intake of taurine is restricted. A deficiency of taurine in cats is expressed by aberrant functions of a wide range of organ systems. Pathological changes occur in the eye, feline central degeneration; reproductive abnormalities occur in the female, a high incidence of fetal resorptions and abortions, low birth weight and survival of live-born young; growth rate in the new born kitten is depressed; heart induction of dilated cardiomyopathy and compromised immune function. All these conditions are prevented or reversed with adequate dietary taurine. While all tissues contain taurine, the concentration varies with the tissue. Generally plasma has been used to assess taurine status in cats, but the concentration of taurine in plasma varies widely. Food deprivation of cats given high taurine diets causes a marked fall in the concentration of taurine in plasma. Major changes in whole blood concentration do not occur as rapidly as plasma and therefore appear to be a superior diagnostic test for taurine status. An inadequate number of samples have been analysed to define a marginal taurine level from whole blood concentration to prevent clinical signs. The minimal dietary concentration of taurine to prevent clinical signs of efficiency is dependent on the type of diet. For commercial expanded (dry) cat foods a concentration of 1200 mg taurine/kg dry matter appears adequate. Higher concentrations are required in canned diets, 2000 to 2500 mg taurine/kg dry matter to supply adequate taurine. The reasons for the higher concentration of taurine required in canned foods is not due to availability of taurine in the classical context. Rather it appears that heating during the canning process produces products which increase enterohepatic loss of taurine. 相似文献

Heart disease is relatively common in cats and our understanding of feline cardiomyopathy has improved considerably over the last two decades, in part as a result of the improved sophistication of non-invasive diagnostic techniques. The incidence of feline dilated cardiomyopathy has declined markedly since the discovery of taurine deficiency as an aetiological factor and subsequent modification of commercial diets. Hypertrophic cardiomyopathy now seems to be the commonest primary form and is characterised by unexplained left ventricular hypertrophy and diastolic dysfunction. Intermediate forms of cardiomyopathy are also recognised. Secondary cardiomyopathies are common; examples of causes include hyperthyroidism, systemic hypertension and acromegaly. Congenital cardiac disease is also well recognised and may lead to clinical signs even late in life. 相似文献

Two nutritional problems of the cat are reviewed. One represents a deficiency of taurine, the other vitamin A toxicity. Taurine deficiency in cats is insidious because the progressive retinal degeneration induced may go unnoticed until the damage is advanced and irreversible. Both rods and cones undergo degeneration along with the underlying tapetum lucidum. The hyperreflective focal lesion is easily observed in the area centralis with an ophthalmoscope and has been previously identified as feline central retinal degeneration. This lesion is not reversed by taurine supplementation, even though the remaining retina may be saved from further degeneration. The cat requires dietary taurine, found in meat and fish, because it cannot synthesize enough to meet demands for bile acid conjugation and tissue metabolism, especially those of muscle and central nervous system.
Vitamin A toxicity is not commonly observed in cats but may occur if cats are fed beef liver in which appreciable vitamin A is stored. Cats exhibit muscle soreness and hyperesthesia, especially along the neck and forelimbs where bony exostoses of cervical verterbrae and longbones are common. The diagnosis is readily made from radiographs. The response to removal of vitamin A from the diet is generally rapid and, unless the toxicity has been chronic in young kittens, recovery is generally satisfactory.

Taurine deficiency retinopathy in the cat 总被引：2，自引：0，他引：2
The literature on feline central retinal degeneration is reviewed and an experiment reported which investigates whether taurine is essential in cats fed a purified diet. The development of taurine deficiency retinopathy is described and illustrated. The histopathological, ultrastructural and ERG changes are also described. Other retinal degenerations in the cat are discussed. 相似文献

There is a great deal of frustration among veterinarians about the diagnosis and treatment of inflammatory diseases of the oral cavity of the cat. This frustration is due to both the high frequency of feline oral inflammatory lesions and our poor understanding of their causes. This poor understanding can be blamed on several things: (1) a rapidly emerging, but still relatively poor, understanding of feline diseases in general and nutrition in particular; (2) a tendency to lump rather than separate specific oral inflammations; (3) a tendency not to use a thorough and systematic approach to diagnosing oral cavity disease; and (4) the reluctance of veterinarians to apply what is already known about human oral cavity diseases to cats. When problems 2 through 4 are adequately addressed, it becomes apparent that we really know more about oral cavity disease in the cat than we thought we knew and that great progress has been made. The task ahead is to define, in precise medical terms, those remaining disease entities of the oral cavity that pose the greatest health risk to cats, to apply what has been already been discovered from human disease counterparts, and to study them systematically. 相似文献

Drug therapy in cats: a systems approach 总被引：1，自引：0，他引：1
D M Boothe 《Journal of the American Veterinary Medical Association》1990,196(9):1502-1511
In the second part of this 4-part series, drug therapy in cats is discussed by use of a systems approach. Specifically, drugs that can be used safely for treatment of disorders affecting the feline gastrointestinal, central nervous, respiratory, cardiovascular, and urogenital systems are described. Many drugs that are used in dogs can be safely used in cats according to the same or similar dosing regimens. Several drugs that have traditionally been considered inappropriate (eg, morphine derivatives, primidone) can probably also be used, if cautiously, in cats. In contrast, use of several drugs that are safely used in other species should be avoided in cats (eg, selected emetics and antiemetics, phosphate salt enemas, and selected urinary antiseptics). Cats are more sensitive than dogs to the adverse side effects of a variety of drugs (eg, aspirin, digoxin, selected antiarrhythmics), and extra precautions must be taken when these drugs are used in cats. Finally, several drugs are used for the treatment of illnesses that tend to be unique to cats (eg, taurine and calcium-channel blockers in selected feline cardiovascular disorders). 相似文献
