Horner''s syndrome following common carotid artery catheterization in cats

Horner's syndrome is characterized by ptosis of the upper eyelid, miosis and enophthalmos and is caused by sympathetic denervation. It has been described in man and animals as a result of trauma, neoplasia, and degeneration of portions of the sympathetic pathway to the eye.
Horner's syndrome was observed following aortography by carotid catheterization in seven of sixteen cats. Changes persisted for 24 hr to 6 weeks. The aetiology appeared to be trauma to sympathetic fibres during dissection of the area for catheterization.
Résumé. Le syndrome de Horner est caracterisé par la ptose de la paupière supérieure, par l'iose et par l'énervation sympathique. On l'a decrit dans l'homme et dans les animaux par suite du trauma, de la neoplase et de la degenerescence de parties du sentier sympathique à l'oeil.
Le syndrome de Horner était observé à la suite d'aortographie par le sondage carotidien dans sept des seize chats. Les changements continuaient pendant vingtquatre heures à six semaines. L'aetiologie apparaissait d'etre le trauma à fibres sympathiques pendant le decoupage de l'aire pour le sondage.
Zusammenfassung. Das Syndrom von Horner wird durch die Ptose des oberen Augenlids, durch die lose und durch die Enophthalme gekennzeichnet und die Ursache ist sympathische Nervenentfernung. Man hat es in Mensch und in Tieren beschrieban, wie eine Folge von der Verletzung, von der Neoplasie und von der Kolloidentartung von Anteilen des sympathischen Laufstegs zum Augen.
Das Syndrom von Horner wird nach der Aortographie von Carotissondierung in sieben der sechszehn Katzen beobachtet. Die Veränderungen beharrten während vierundzwanzig Stunden bis sechs Wochen. Die Aetiologie erschien, die Verletzung zu den sympathischen Fasen während der Zerlegung des Areas für Sondierung, zu sein.     

Colorimetric assay for the detection of benzimidazole resistance in trichostrongyles

A modified version of the aphid tile-test, which is used to detect insecticide resistance in single adult aphids that are resistant or susceptible to organophosphate or carbamate insecticides, was used to compare the levels of non-specific esterases in strains of the trichostrongyle nematodes Haemonchus contortus, Ostertagia circumcincta and Trichostrongylus colubriformis which were known to be resistant or susceptible to benzimidazole (BZ) anthelmintics. This colorimetric assay has shown that there is significantly more non-specific esterase in the infective-stage larvae of BZ-resistant strains than in susceptible strains and this may prove to be of use in the detection of resistance to benzimidazole anthelmintics.     

Antigen expression in cultured oral keratinocytes from dogs

Oral keratinocytes from dogs were cultured on either collagen gels or artificial matrices at the air-liquid interface, and the expression of keratinocyte antigens and basement membrane components was determined, using various monoclonal and polyclonal antibodies. Keratinocytes grown on collagen gels expressed pemphigus vulgaris, pemphigus foliaceous, and bullous pemphigoid antigens. Diffuse, suprabasal, and superficial keratinocyte membrane differentiation antigens identified by various monoclonal antibodies also were expressed in a pattern identical to that observed in the native tissue. Laminin and type-IV collagen were deposited at the keratinocyte-collagen interface in a patchy distribution. When synthetic matrices were used, the oral keratinocytes differentiated, but to a lesser extent than cells grown on collagen gels. Antigen expression for cells grown on synthetic matrices was similar to that for cells on collagen, except for failure of the keratinocytes on synthetic membranes to express superficial cell antigens and pemphigus foliaceous antigens.     

Spontaneous mesangiocapillary glomerulonephritis in Finn cross lambs from Alberta.

A spontaneous mesangiocapillary glomerulonephritis occurred in three, one to three month old Finnish Landrace cross lambs from a flock in northern Alberta. The ram was a purebred Finn sheep, and the ewes were Finn-Rambouillet and Finn-Suffolk-Rambouillet crosses. The lambs were found dead without previous clinical signs. Histologically there was marked thickening of glomerular capillary basement membranes, proliferation of mesangial cells, and peri-glomerular fibrosis. An interstitial infiltration of plasma cells and lymphocytes was present with occasional tubular degeneration and proteinaceous cast formation. Focal leukoencephalomalacia was present in one lamb. Electron microscopy demonstrated deposition of electron-dense deposits in a subendothelial location with occasional fusion of overlying foot processes in glomerular capillaries. Indirect immunofluorescence studies demonstrated positive staining material in glomerular capillary walls. These findings in Finnish Landrace cross lambs are characteristic of mesangiocapillary glomerulonephritis, a condition heretofore not reported in North America.     

Effect of dietary energy intake during lactation on performance of primiparous sows and their litters

A total of 146 primiparous sows was used in four replications of an experiment to investigate the effect of energy intake during a 28-d lactation on sow and litter performance. Dietary treatments consisted of three energy intakes; 10, 12 or 14 Mcal of metabolizable energy (ME) X sow-1 X d-1. All sows were fed equal amounts of crude protein, vitamins and minerals daily, which met or exceeded standard recommendations. The experiment was initiated at parturition. Sow weight and backfat loss during lactation decreased linearly (P less than .001) as energy intake increased. There were no differences in litter size at either 14 d of lactation or weaning. Pig weights on d 14 increased linearly (P less than .05) and litter weights tended to increase linearly (P = .13) as energy intake increased. At weaning, pig weights and litter weights increased (P less than .05) as sow energy intake increased. There were no significant differences in the percentages of sows in estrus by 7, 14, 21 and 70 d postweaning, but sows fed 10 Mcal ME/d had a slightly longer interval from weaning to first estrus than sows fed higher energy intakes. Serum urea concentrations of sows were inversely related to energy intake during lactation. Serum creatinine concentrations were not affected by energy intake. An intake of 10 Mcal ME/d by primiparous sows during a 28-d lactation resulted in reduced sow and litter performance; there was little difference between sows fed 12 and 14 Mcal ME/d.
