Fibrocartilaginous embolism and ischemic myelopathy in a four month old German shepherd dog.          下载免费PDF全文

C E Doige  J M Parent 《Canadian journal of veterinary research》1983,47(4):499-500

Clinical signs and postmortem findings are described in a four month old German Shepherd dog with fibrocartilaginous embolism of the spinal cord. Ischemic myelopathy involved spinal cord segments C7 to L1. No evidence of degeneration or herniation of intervertebral discs was found at necropsy.  相似文献

Isotopic fractionation of stratospheric nitrous oxide     

YL Yung  CE Miller 《Science (New York, N.Y.)》1997,278(5344):1778-1780

We propose an isotopic fractionation mechanism, based on photolytic destruction, to explain the 15N/14N and 18O/16O fractionation of stratospheric nitrous oxide (N2O) and reconcile laboratory experiments with atmospheric observations. The theory predicts that (i) the isotopomers 15N14N16O and 14N15N16O have very different isotopic fractionations in the stratosphere, and (ii) laboratory photolysis experiments conducted at 205 nanometers should better simulate the observed isotopic fractionation of stratospheric N2O. Modeling results indicate that there is no compelling reason to invoke a significant chemical source of N2O in the middle atmosphere and that individual N2O isotopomers might be useful tracers of stratospheric air parcel motion.  相似文献

Suppurative cholangitis in cats     

V M Hirsch  C E Doige 《Journal of the American Veterinary Medical Association》1983,182(11):1223-1226

Suppurative cholangitis in 5 aged cats was characterized clinically by weight loss, depression, dehydration, icterus, and fever. The major abnormal laboratory findings were a severe left shift of WBC and a high, conjugated bilirubin concentration consistent with an inflammatory process and cholestasis. Gross pathologic findings included periductal biliary fibrosis (4 cats), periductal pancreatic fibrosis (2 cats), cholelithiasis (2 cats), deformation of the gallbladder (2 cats), and chronic interstitial pancreatitis (2 cats). Histopathologic findings in all cases were portal hepatic fibrosis, biliary hyperplasia, and suppurative exudate within dilated intrahepatic biliary ducts. Weight loss and portal fibrosis were suggestive of chronic, intermittent illness. The pathogenesis appeared to involve invasion of the bile duct by enteric bacteria. Cholangitis was observed to occur in association with pancreatitis, cholelithiasis, or anatomic abnormalities of the biliary tract.  相似文献   

Posterior paralysis due to fibrocartilaginous embolism in two weaner pigs.   总被引：1，自引：0，他引：1       下载免费PDF全文

S V Tessaro  C E Doige    C S Rhodes 《Canadian journal of veterinary research》1983,47(2):124-126

Acute posterior paralysis in two weaner pigs was attributed to ischemic infarction of the lumbar spinal cord due to fibrocartilaginous emboli. These arterial and venous emboli were assumed to have originated from the nucleus pulposus of one or more intervertebral discs. There was no indication of an initiating factor in either instance, although some form of trauma may have been involved. Lesions were not grossly evident and were limited to one or two lumbar segments. Although it appears to be a rare occurrence, fibrocartilaginous embolism of the spinal cord should be considered in cases of acute paralysis in pigs particularly when gross lesions are absent.  相似文献   

Effect of viral dose on experimental pneumonia caused by aerosol exposure of calves to bovine herpesvirus 1 and Pasteurella haemolytica.   总被引：1，自引：1，他引：0       下载免费PDF全文

W D Yates  K W Jericho    C E Doige 《Canadian journal of veterinary research》1983,47(1):57-63

The effect of various aerosol doses of bovine herpesvirus 1, followed four days later by aerosol exposure to a constant level of Pasteurella haemolytica, was studied in 16 crossbred Hereford range calves. A Collision nebulizer was used to generate aerosols from virus suspensions with concentrations of 10(8.2) (high), 10(5.2) (moderate) or 10(2.2) (low) TCID50/mL. The bacterial suspension contained 10(7) colony forming units/mL. Control calves exposed only to P. haemolytica developed no pulmonary lesions. Calves in the low, moderate and high virus exposure groups developed lobular areas of atelectasis; in addition, one calf in the moderate and all four in the high virus exposure group developed fibrinous pneumonia. One of the latter calves died. The 50% effective dose for fibrinous pneumonia under these experimental conditions was 10(6.0) TCID50 bovine herpesvirus 1/mL of suspension in the nebulizer reservoir, and approximately 10(4.0) infectious units inhaled per calf.  相似文献   

A study of articular surfaces and synovial fossae of the pectoral limb of swine.          下载免费PDF全文

C Doige  A Horowitz 《Canadian journal of veterinary research》1975,39(1):7-16

Articular surfaces of the pectoral limb were studied in 50 swine and are described in detail. Synovial fossae were not present at birth but were found commonly on the articular surface of the scapula, distal humerus, proximal radius, distal radius and distal surfaces of the intermediate carpal bone after four to five months of age. When present, they were bilaterally symmetrical and were located at the depth of a concavity of the articular surface. Microscopically, synovial fossae appeared as an invagination of articular cartilage extending into subchondral bone. Evidence of endochondral bone formation was less apparent at the depth of synovial fossae than in areas of weight bearing cartilage.  相似文献
