Low central venous oxygen saturation is associated with increased mortality in critically ill dogs     

Hayes GM  Mathews K  Boston S  Dewey C 《The Journal of small animal practice》2011,52(8):433-440

Objectives : To investigate relationships between central venous oxygen saturation (ScvO₂) and survival to hospital discharge in dogs. Central venous oxygen saturation is an accessible measure of the balance between systemic oxygen delivery and consumption. Methods : Prospective observational cohort study, enrolling 126 client‐owned dogs with central venous catheters. Central venous oxygen saturation was measured over the 24 hours following intensive care unit admission. Poor outcome was defined as death or euthanasia performed for moribund status. Regression analysis identified independent predictors of non‐survival and physiologic parameters associated with central venous oxygen saturation. Area under the receiver operator curve analysis identified a cut‐off point of central venous oxygen saturation, below which central venous oxygen saturation decrease was associated with increased mortality risk. Results : Mortality risk was 30·9%. Low central venous oxygen saturation was associated with poor outcome (P<0·05). Area under the receiver operator curve analysis selected a central venous oxygen saturation of 68% as the point below which a fall in central venous oxygen saturation was associated with increased mortality risk. For each 10% drop in central venous oxygen saturation below 68%, odds of non‐survival increased by 2·66 times (P=0·0002, 95% confidence interval of odds ratio=1·45 to 4·85). Central venous oxygen saturation was equivalent to lactate in predicting non‐survival. Predictors of central venous oxygen saturation (packed cell volume, mean arterial blood pressure, fever, % arterial haemoglobin saturation as measured by pulse oximeter) were consistent with hypothesised physiologic mechanisms. Clinical Significance : Central venous oxygen saturation was a strong mortality predictor. Further work is needed to determine if therapy targeting central venous oxygen saturation can reduce mortality in canine intensive care unit patients.  相似文献   

The clinical and hematological effects of Brucella abortus strain 19 in seronegative horses     

Wade Mathews DVM  Paul Nicoletti DVM  MS 《Journal of Equine Veterinary Science》1984,4(5):198-214

Three mares which were seronegative to Brucella abortus were subcutaneously inoculated with 7.2 × 10¹⁰ Strain 19 organisms. The clinical and hematological effects were studied. A control mare was used for comparisons. All inoculated mares became febrile and lethargic. In addition, they showed an elevated leukogram along with development of high serum titers.  相似文献   

The Prevalence of Malignant Neoplasia in Feline Renal-Transplant Recipients

OBJECTIVE: To determine the prevalence of malignant neoplasia in a group of feline renal-transplant recipients (FRTR). STUDY DESIGN: Retrospective clinical study. ANIMALS: Ninety-five consecutive client-owned FRTR treated at the University of California, Davis, between 1987 and 1997. METHODS: Medical records of the 95 cats were examined. The time to occurrence and type of malignant neoplasia, if present, was determined. RESULTS: Nine of 95 cats (9.5%) developed apparently de novo malignant neoplasia after receiving renal allografts. The predominant type of neoplasm was lymphoma. The median time to diagnosis of neoplasia in these 9 patients was 9.0 months after transplantation, whereas the median survival time was 14.0 months after transplantation. This compares with a median survival time of 22 months after transplantation for cats that died for reasons other than development of malignant neoplasia. CONCLUSIONS: Although these transplant recipients were not compared with a control population, it would appear that, as in humans, malignant neoplasia is encountered with greater-than-expected frequency after renal transplantation and immunosuppression in cats. CLINICAL SIGNIFICANCE: The apparent propensity to develop malignant neoplasia after renal transplantation and immunosuppression in cats is a fatal complication of which owners and clinicians should be aware.  相似文献   

An outbreak of malignant catarrhal fever in young rusa deer (Cervus timorensis)     

NW TOMKINS  NN JONSSON  MP YOUNG  AN GORDON  KA McCOLL 《Australian veterinary journal》1997,75(10):722-723

On the basis of clinical signs and histological findings eight 9-month-old male rusa deer ( Cervus timorensis ) were diagnosed with sheep associated-malignant catarrhal fever. Following a variable course involving rectal temperatures around 40.5°C, depression, inappetence, diarrhoea, corneal opacity and hypopyon all animals died or were euthanased over a 5-week period. Severe multifocal vasculitis, mainly periglomerular and in the arcuate vessels were consistent histological findings which in the past have been adequate to confirm clinical diagnosis of sheep associated-malignant catarrhal fever. A nested poly-merase chain reaction test has been used to detect a sheep associated-malignant catarrhal fever PRC product, 238 base-pairs in size, in DNA extracted from lymphocyte preparations. The result supported the diagnosis of sheep associated-malignant catarrhal fever in these deer.  相似文献

Growth and regeneration of plantlets in callus cultures of pineapple     

V.Helena Mathews  T.S. Rangan 《Scientia Horticulturae》1981,14(3):227-234

Callus cultures were established from the basal region of in vitro-obtained shoot buds on MS medium supplemented with CH + CW + NAA. Such callus cultures, when grown on MS medium devoid of any growth regulators, regenerated shoot buds and optimum regeneration was obtained on MS + CW (5% v/v) medium. Addition of BA did not enhance shoot bud regeneration, but two variants (albino types) were observed among the BA-induced regenerants. The callus-regenerated shoot buds produced multiple shoots when transferred to MS + NAA + IBA + K medium. The plantlets were induced to root on a modified White's medium + NAA + IBA and subsequently transferred to soil.  相似文献

Magnetic Field and Plasma Observations at Mars: Initial Results of the Mars Global Surveyor Mission   总被引：2，自引：0，他引：2

The magnetometer and electron reflectometer investigation (MAG/ER) on the Mars Global Surveyor spacecraft has obtained magnetic field and plasma observations throughout the near-Mars environment, from beyond the influence of Mars to just above the surface (at an altitude of approximately 100 kilometers). The solar wind interaction with Mars is in many ways similar to that at Venus and at an active comet, that is, primarily an ionospheric-atmospheric interaction. No significant planetary magnetic field of global scale has been detected to date (<2 x 10(21) Gauss-cubic centimeter), but here the discovery of multiple magnetic anomalies of small spatial scale in the crust of Mars is reported.  相似文献
