Four cats were investigated because they lost weight while eating well. One cat was found to have hypoinsulinaemic diabetes mellitus, and another had maldigestion caused by exocrine pancreatic atrophy. An enteropathy with presumed intestinal malabsorption was diagnosed in the third case. The fourth cat had hyperthyroidism and disseminated amyloidosis. The diabetic animal has been maintained satisfactorily on daily insulin injections for 2 ½ years, but treatment in the other three cases was either unsuccessful or not attempted. Weight loss is uncommon in cats which are eating well. In investigating this syndrome, it is suggested that initially urine should be tested for glucose and faeces examined for maldigestion or malabsorption. More specific tests for diabetes mellitus, pancreatic maldigestion, intestinal malabsorption or hyperthyroidism might then be indicated. 相似文献

Oedema associated with obstruction of the lymphatic pathways is termed lymphoedema. A number of cases of primary lymphoedema attributed to congenital lymphatic abnormalities have been reported in dogs. Cases associated with secondary or acquired lymphatic drainage failure are rare. This paper reports a dog with generalized peripheral oedema in which a presumptive diagnosis of secondary lymphoedema was made and discusses the causes, investigation and treatment of lymphoedema. 相似文献

Kidney specimens from 12 dogs with congenital portosystemic shunts were examined histologically. Glomerulopathy of variable severity was present in the kidney sections of all 12. Marked irregular thickening of the glomerular capillary wall was the most prominent pathological change, the renal interstitium being largely unaffected. The severity of lesions was not correlated with the age of dogs at the time of necropsy. An immunoperoxidase technique failed to demonstrate significant IgA or IgG deposition in affected glomeruli. Proteinuria was generally mild or absent despite significant glomerular lesions, except in dogs with concurrent urinary tract infection. 相似文献

PNU-87407 and PNU-88509, β-ketoamide anthelmintics that are structurally related to each other and to the salicylanilide anthelmintic closantel, exhibit different anthelmintic spectra and apparent toxicity in mammals. The basis for this differential pharmacology was examined in experiments that measured motility and adenosine triphosphate (ATP) levels in larval and adult stages of the gastrointestinal nematode, Haemonchus contortus , and in a vertebrate liver cell line and mitochondria. PNU-87407 and PNU-88509 both exhibited functional cross-resistance with closantel in larval migration assays using closantel-resistant and -sensitive isolates of H. contortus . Each compound reduced motility and ATP levels in cultured adult H. contortus in a concentration- and time-dependent manner; however, motility was reduced more rapidly by PNU-88509, and ATP levels were reduced by lower concentrations of closantel than the β-ketoamides. Tension recordings from segments of adult H. contortus showed that PNU-88509 induces spastic paralysis, while PNU-87407 and closantel induce flaccid paralysis of the somatic musculature. Marked differences in the actions of these compounds were also observed in the mammalian preparations. In Chang liver cells, ATP levels were reduced after 3 h exposures to 0.25 μ M PNU-87407, 1 μ M closantel or 10 μ M PNU-88509. Reductions in ATP caused by PNU-88509 were completely reversible, while the effects of closantel and PNU-87407 were irreversible. PNU-87407, closantel and PNU-88509 uncoupled oxidative phosphorylation in isolated rat liver mitochondria, inhibiting the respiratory control index (with glutamate or succinate as substrate) by 50% at concentrations of 0.14, 0.9 and 7.6 μ M , respectively. 相似文献
