Expression of claudins in the normal canine gastric mucosa.

The aim of the present study was to investigate the expression pattern of claudin-1, -2, -3, -4, -5, -7, -8, -10 and -18 in the intact fundic and pyloric gastric mucosa of dogs. Intense, linear, membranous claudin-18 positivity was detected in the surface gastric cells and in the epithelial cells of the gastric glands both in the fundic and pyloric stomach regions. The mucous neck cells in the apical part of the glands, furthermore the parietal cells and chief cells of the basal part of the gland were all positive for claudin-18, in the same way as the enteroendocrine cells.

Effect of enteral feeding on gallbladder function in dogs.

Nutritional support in critically ill patients is a fundamental principle of patient care. Little is known about gallbladder motility during the interdigestive phase and in response to enteral feeding. The objective of this study was to investigate the effect of enteral feeding on gallbladder function in dogs.

Cholagogue-induced gallbladder emptying in the diagnosis of canine biliary obstruction.

The efficacy of ultrasound-guided cholagogue-induced gallbladder emptying for differentiating obstructive from non-obstructive hepatobiliary diseases was studied in icteric dogs. In 7 healthy Beagle dogs, Lipofundin 20% infusion (2 ml/kg orally) evoked a vigorous gallbladder contraction of 44.2% (range: 35.

Occurrence, clinical features and outcome of canine pancreatitis (80 cases).

Medical records of 80 dogs diagnosed with acute pancreatitis during a 4-year period were evaluated regarding history, breed predilection, clinical signs and additional examination findings. Cases were selected if compatible clinical symptoms, increased serum activity of amylase or lipase and morphologic evidence of pancreatitis by ultrasonography, laparotomy or necropsy were all present. Like in other studies, neutered dogs had an increased risk of developing acute pancreatitis.

Endoscopically guided nasojejunal tube placement in dogs for short-term postduodenal feeding.

Objective: To evaluate a method for endoscopically guided nasojejunal tube placement allowing short-term postduodenal feeding and chyme withdrawal in dogs.

Design: Pilot study.

Setting: University teaching hospital.

Prevalence and features of canine atopic dermatitis in Hungary.

Medical records of 600 dogs diagnosed with atopic dermatitis were reviewed and evaluated with reference to history, geographical distribution, breed predilection, clinical signs and positive reactions to allergens as determined by intradermal skin testing (IDT) manufactured by Artuvetrin Laboratories. In 66.6% of dogs, the age of onset of atopic dermatitis was between 4 months and 3 years.
