摘要:

SummaryPericarditis and pericardial effusion are considered to occur rarely in the horse. The clinical and laboratory features of idiopathic pericarditis with effusion diagnosed in 10 horses over a seven‐year period were reviewed. Consistent physical findings included tachycardia, ventral oedema, jugular venous distention and diminished heart sounds. Electrocardiographic features included diminished voltages and electrical alternans, and the effusion was identified by echocardiography in the six horses in which it was performed. Pericardiocentesis relieved clinical signs in nine horses. Laboratory anaylsis of pericardial fluid samples classified six cases as aseptic serofibrinous, three cases as eosinophilic, and one case as histiocytic. One horse died and three were destroyed. The remaining six horses recovered following pericardiocentesis (performed once or twice) with or without corticosteroid treatment, and were alive one month to seven years after diagnosi

摘要:

SummaryA retrospective study of 119 cases of fracture of the proximal phalanx is described. The short incomplete sagittal fracture (split pastern) was most common and carried a good prognosis for a return to racing following conservative treatment. Longer incomplete fractures also had a good prognosis but complete fractures, either through the lateral cortex of the proximal phalanx or through the bone into the proximal interphalangeal joint, required internal fixation. Careful assessment of these and comminuted fractures was essential before surgery was undertaken. Most comminuted fractures were treated with a view to the animal retiring to stud rather than racing again. Humane destruction was considered to be justifiable for such fractures in colts or geldings of no stud value or if the fracture was severely comminuted.

摘要:

SummaryFour horses were stabled and fed a diet of hayad libitum, and 2 kg oats per animal per day, for a month. The basic diet was then supplemented with molybdenum, at a rate of 20 mg/kg dry matter for 4.5 months. For one month of this period the diet was supplemented also with sulphur at a rate of 1.2 g/kg dry matter. Analyses of jugular blood samples, obtained at intervals varying between two and 20 days, showed no evidence of a decline in total plasma copper or of an increased proportion of trichloroacetic acid (TCA) insoluble copper in plasma over this period. In separate studies, two other horses were given “molybdenum (molybdate, 20 to 28 mg Mo, 4 mCi per animal)per os, initially while being fed the basic diet and later while maintained on the molybdenum supplemented diet.99Molybdenum appeared rapidly in plasma, but the radioactivity was then quickly cleared (half‐life 7 to 10 h). The99molybdenum present was identified as (99Mo)‐molybdate. There was no evidence of the persistent, protein‐bound (99Mo)thiomolybdates which appear in ruminants. These studies indicate that increased dietary molybdenum is unlikely to interfere with copper metabolism in

摘要:

SummaryIn 27 potential neuropathies an enzyme‐linked immunosorbant assay, using P2preparations from either bovine or equine myelin, detected all cases of cauda equina neuritis in which there was caudal involvement. The test was of limited value in differentiating neuropathies involving only cranial or other peripheral nerve

摘要:

SummaryIn a two‐part cross‐over experiment in six ponies, an acute inflammatory reaction was generated by injecting carrageenin solution into subcutaneously‐implanted tissue‐cages lined with fibrovascular granulation tissue. In each part of the cross‐over, half of the ponies received a novel phenylpyrazoline antiinflammatory agent (BW540C) orally and half received a placebo treatment. BW540C inhibited platelet cyclo‐oxygenase for 24 h but the reductions in exudate eicosanoid concentrations were less pronounced. A significant suppression in the rise of surface skin temperature in BW540C‐treated ponies paralleled drug‐induced inhibition of thromboxane B2bicyclic prostaglandin (PG) E2concentrations at the inflamed site. The drug had no significant effect on 6‐keto‐PGF1α, migrating leucocytes, lactate dehydrogenase or total protein in exudates. Maximum plasma concentrations of both compounds occurred 2 to 4 h after dosing and maximum exudate levels of drug and metabolite occurred at 12 h. Both compounds penetrated approximately three times less readily into exud
