During a 2-year period from January 1, 1999, to December 31, 2000, 77 diagnoses of mulberry heart disease (MHD) were documented at the Iowa State University Veterinary Diagnostic Laboratory. Mean (+/- SD) liver vitamin E concentrations were lower (P < 0.05) in pigs with MHD (3.12 +/- 1.12 ppm, wet weight) than in pigs that died of causes other than MHD (4.80 +/- 3.2 ppm, wet weight). The majority of the pigs affected with MHD ranged in age from 3 to 7 weeks. Statistical influence of age was found on the concentration of vitamin E (P < 0.01) but not on concentration of selenium in liver in pigs with MHD. Concentrations of vitamin E below 2 ppm were considered deficient. Hepatic vitamin E concentrations below 2 ppm were measured in 25% of the pigs with gross and microscopic lesions of MHD. In contrast, liver selenium concentrations were adequate in all pigs. 相似文献

A seven year old Welsh pony stallion was admitted to the Veterinary Medicine Teaching Hospital for treatment of smoke inhalation injury (SII) sustained in a barn fire. The pony was severly affected and demonstrated the three clinical phases typically described with SII. A nuclear pulmonary perfusion scan demonstrated multiple areas of unperfused lung suggesting reflex hypoxic pulmonary vasoconstriction, while thoracic radiographs showed only a mild increase in broncho-interstitial pattern. The pony responded well to treatment with oxygen, diuretics, intravenous fluids, bronchodilators, non-steroidal antiinflammatory agents and antibiotics. A tracheostomy was done to relieve upper airway obstruction and to facilitate removal of tracheobonchial pseudomembranous casts. Ultrasonic nebulization and to facilitate removal of tracheobonchial pseudomembranous casts. Ultrasonic nebulization was utilized to moisturize and break up secretions and casts and to deliver bronchodilatory agents. The pony recovered and seven months following the fire was pasture breeding mares. The pathophysiology and treatment of SII in the equine is discussed. 相似文献

A competitive enzyme-linked immunosorbent assay (C-ELISA) for the detection of antibodies against vesicular stomatitis virus New Jersey (VSV-NJ) and vesicular stomatitis virus Indiana (VSV-IN) was compared with the serum neutralization test (SNT) using 1,106 serum samples obtained from dairy cattle on sentinel study farms in the Poás region of Costa Rica. Kappa coefficients between the C-ELISA and the SNT were 0.8871 (95% confidence interval [CI]: 0.8587-0.9155) and 0.6912 (95% CI: 0.6246-0.7577) for the VSV-NJ and VSV-IN tests, respectively. These results indicate good to excellent agreement between the 2 tests under these conditions. 相似文献

The UV-A and UV-B wavelengths of solar radiation may seriously reduce viability of Metarhizium anisopliae conidia,a fungus used extensively in Brazil for insect pest control.The conidial tolerances to UV-A and UV-B radiation were studied for one isolate(IBCB 425) commercially available product produced on rice grains.Aqueous or oil emulsion conidial suspensions were irradiated for 0(control),2,or 3 h using the solar simulator filtered with diacetate filter to remove UV-C radiation which afforded 652 mW·m-2 in the spectral range of 280~370 nm.The UV tolerance was based on conidial germination(viability) and virulence to Diatraea saccharalis larvae.Conidia formulated with oil emulsion had higher survival after 3 h of UV exposure,but the virulence of the conidia previously exposed to 2 h of UV radiation were similar when oil formulated or not.The mortality of D.saccharalis caterpillars exposed to non-UV-irradiated conidia was greater than that of larvae exposed to irradiated conidia,and the LT50 values were lower for the non-irradiated suspensions than for those irradiated.This apparent reduction in virulence was directly related reduction in viability or delay of germination of UV-irradiated conidia. 相似文献
