1 A novel animal model of spontaneous colonic inflammation, the multiple drug-resistant (mdr1) a(-/-) mouse, was identified by Panwala and colleagues in 1998. The aim of our study was to further characterise this model, specifically by measuring cytokines that have been implicated in inflammatory bowel disease (IBD) (IL-8 and IFN-gamma) in the colon/rectum(More)
We aimed to investigate the toxicity of carbon monoxide (CO) in rats with right ventricle (RV) remodeling induced by hypoxic pulmonary hypertension (PHT). A group of Wistar rats was exposed to 3-wk hypobaric hypoxia (H). A second group was exposed to 50 ppm CO for 1 wk (CO). A third group was exposed to chronic hypoxia including 50 ppm CO during the third(More)
The time-related metabolic events in rat liver, plasma, and urine following hepatotoxic insult with allyl formate (75 mg/kg) were studied using a combination of high-resolution liquid state and magic angle spinning (MAS) nuclear magnetic resonance (NMR) spectroscopic methods together with pattern recognition analysis. The metabonomics results were compared(More)
Cutaneous papillomavirus infection was diagnosed in a 6-year-old female Boxer dog that was under long-term corticosteroid therapy for atopic dermatitis. Multiple black, rounded papules were present on the ventral skin. Spontaneous regression occurred within 3 weeks after cessation of corticosteroids. Histologically, the lesions consisted of well-demarcated(More)
A distinctive nodular dermatitis induced by Straelensia cynotis, a newly described trombidioid larval mite which resides in hair follicles, was identified in 12 dogs living in France. They all had scattered, small (1 to 3 mm in diameter), pale, firm skin nodules, variable in distribution but always affecting the dorsal regions of the head and trunk; they(More)
Phosphodiesterase 4 (PDE4) inhibitors are potential therapeutic agents but vascular injury and perivascular inflammation occurs frequently during preclinical toxicology testing of these drugs. The lesions induced by PDE4 inhibitors have been described mainly in rats but there is limited data available for monkeys and no data for dogs. Here we present the(More)
New N-(1,2-diphenylethyl)piperazines 6 are disclosed as dual serotonin and noradrenaline reuptake inhibitors (SNRI) which may have potential in treating stress urinary incontinence (SUI). In this Letter, we present new data for SNRI PF-526014 (4) including performance in a canine in vivo model of SUI, cardiovascular assessment, pharmacokinetics in dog and(More)
1. This study assessed urinary creatine excretion as a marker for testicular atrophy. 2. Male rats received a single i.p. dose of 2-methoxyethanol at 0, 250 or 750 mg kg-1 and were sacrificed 2 d later. Urinary creatine and creatinine excretion were measured on days 0, 1 and 2. 3. Decreased testicular weights and histopathological assessment revealed(More)
