In Vitro Evaluation of Evacuated Blood Collection Tubes as a Closed-Suction Surgical Drain Reservoir.

The initial negative pressures of evacuated blood collection tubes (EBCT) and their in vitro performance as a rigid closed-suction surgical drain (CSSD) reservoir has not been evaluated in the scientific literature despite being described in both human and veterinary texts and journals. The initial negative pressures of EBCT sized 3, 6, 10, and 15 mL were measured and the stability of the system monitored. The pressure-to-volume curve as either air or water was added and maximal filling volumes were measured.

Evaluation of fluorescence in situ hybridization for the detection of bacteria in feline inflammatory liver disease.

The etiopathogenesis of feline inflammatory liver disease (ILD) is unclear. Therefore, we sought to determine the presence and distribution of bacteria within the livers of cats with ILD using eubacterial fluorescence in situ hybridization (FISH). Histopathology from 39 cats with ILD and 19 with histologically normal livers (C) were classified using World Small Animal Veterinary Association guidelines.

Hepatic dysfunction.

This article reviews the common pathophysiology that constitutes hepatic dysfunction, regardless of the inciting cause. The systemic consequences of liver failure and the impact of this condition on other organ systems are highlighted. The diagnostic tests available for determining the cause and extent of liver dysfunction are outlined, treatment strategies aimed at supporting hepatic health and recovery are discussed, and prognosis is briefly covered.

Assessment of oxidative stress in leukocytes and granulocyte function following oral administration of a silibinin-phosphatidylcholine complex in cats.

Objective: To determine the effect of oral administration of a silibinin-phosphatidylcholine complex (SPC) on oxidative stress in leukocytes and granulocyte function in healthy cats.

Animals: 10 purpose-bred adult cats.

Procedures: Cats were administered SPC (10 mg/kg/d) orally for 5 days; blood samples were collected prior to and immediately after the 5-day treatment period.

Effects of an oral superoxide dismutase enzyme supplementation on indices of oxidative stress, proviral load, and CD4:CD8 ratios in asymptomatic FIV-infected cats.

This study was designed to test the effect of antioxidant supplementation on feline immunodeficiency virus (FIV)-infected felines. Six acutely FIV-infected cats (> or =16 weeks post-inoculation) were given a propriety oral superoxide dismutase (SOD) supplement (Oxstrin; Nutramax Laboratories) for 30 days. Following supplementation, the erythrocyte SOD enzyme concentration was significantly greater in the supplemented FIV-infected group than the uninfected control group or the unsupplemented FIV-infected group.

Unilateral improvement in glomerular filtration rate after permanent drainage of a perinephric pseudocyst in a cat.

A 12-year-old, 6 kg, castrated male Siamese-cross cat was referred for investigation of an abdominal mass. The cat was found to have a left perinephric pseudocyst (PNP), accompanied by azotemia, with a small right kidney detected on ultrasound. Glomerular filtration rate (GFR) was determined by renal scintigraphy and was found to be low, with the left kidney contributing 64% of the total GFR.

Oxidative stress during acute FIV infection in cats.

Oxidative stress is thought to contribute to the pathogenesis of HIV infection in humans. For example, CD4(+) T cells are particularly affected in HIV patients and oxidative stress may also contribute to impairment of neutrophil function in HIV/AIDS patients. Since cats infected with FIV develop many of the same immunological abnormalites as HIV-infected humans, we investigated effects of acute FIV infection on oxidative stress in cats.

Rectal strictures in 19 dogs: 1997-2005.

The etiologies for nonneoplastic rectal strictures in dogs included foreign bodies, postoperative formation, inflammatory disease, and congenital malformation. Sixteen of 19 dogs underwent balloon dilatation therapy, and 14 of these 16 dogs received intralesional triamcinolone injections. Following dilatation, clinical signs persisted in one dog, improved with continued medical therapy in five dogs, and resolved in nine dogs for the duration of their follow-up period (mean 18 months; median 12 months); one dog was lost to follow-up.

Neutrophil function in septic dogs.

Background: Leukocytes appear to enter a hypo-inflammatory state in human patients with a severe bacterial infection, whereas, in swine, intra-abdominal sepsis produces an initial increase and subsequent decrease in neutrophil Fc receptor mediated phagocytosis.

Hypothesis: Impaired neutrophil function (hypo-inflammatory state) develops in dogs with sepsis.

Animals: Thirteen adult client-owned dogs that developed clinical signs consistent with sepsis were assessed for evidence of neutrophil dysfunction.

TGF-beta and IL-13 synergistically increase eotaxin-1 production in human airway fibroblasts.

Chronic diseases may involve an "innate" response followed by an adaptive immune response, of a Th1 or Th2 variety. Little is known regarding the interactions of these responses. We hypothesized that TGF-beta1 (innate response factor associated with wound repair) in combination with IL-13 (Th2 factor) might augment inflammatory processes associated with asthma.
