Serum pancreatic polypeptide and amylase concentrations in dogs with experimentally induced acute pancreatitis   总被引：1，自引：0，他引：1  

R J Murtaugh  R M Jacobs  R G Sherding  T M O'Dorisio 《American journal of veterinary research》1985,46(3):654-656

Serum concentrations of immunoreactive pancreatic polypeptide (IPP) were measured serially for 7 days after experimental induction of acute hemorrhagic pancreatitis in dogs by infusion of oleic acid into the pancreatic duct. The mean serum IPP concentrations in dogs with pancreatitis were increased significantly (P = 0.013) for 96 hours after induction of pancreatitis. Providing food at 108 hours resulted in significant increases (P = 0.032) in mean serum IPP concentrations in sham-operated control dogs compared with dogs with induced pancreatitis. This was attributed to cephalic-phase release of IPP due to a conditioned response that resulted from feeding immediately after each blood sampling. Mean serum IPP concentrations returned to base line more quickly than did mean serum amylase concentrations in dogs with pancreatitis.  相似文献   

Acute hepatic failure     

R G Sherding 《Veterinary Clinics of North America: Small Animal Practice》1985,15(1):119-133

Acute hepatic failure is characterized by a sudden catastrophic compromise of hepatic failure that causes clinical signs such as anorexia, depression, vomiting, diarrhea, icterus, and encephalopathy. Injurious hepatotoxins, drugs, infectious agents, or metabolic disturbances can cause acute hepatic failure; however, in many cases, the inciting cause is not determined. Treatment is aimed at controlling complications such as fluid-electrolyte imbalances, hepatic encephalopathy, hypoglycemia, bleeding diathesis, gastric ulcer, sepsis, and endotoxemia, in order to provide time for liver regeneration and recovery.  相似文献   

Clinicopathologic findings resembling hypoadrenocorticism in dogs with primary gastrointestinal disease   总被引：1，自引：0，他引：1  

S P DiBartola  S E Johnson  D J Davenport  J C Prueter  D J Chew  R G Sherding 《Journal of the American Veterinary Medical Association》1985,187(1):60-63

Nine dogs with primary gastrointestinal disease had clinical and laboratory findings resembling hypoadrenocorticism. The dogs had histories of anorexia, weakness or lethargy, diarrhea, vomiting, and weight loss. Hypothermia, dehydration, and emaciation also were detected on physical examination. Hyponatremia, hyperkalemia, and abnormally low Na/K ratios were found on laboratory evaluation, but results of ACTH-response tests were not compatible with hypoadrenocorticism. The primary diagnoses were trichuriasis and salmonellosis in 2 dogs, trichuriasis in 5 dogs, and perforated duodenal ulcer in 2 dogs. Most dogs responded to medical or surgical treatment of their primary gastrointestinal disease, and the original electrolyte abnormalities resolved. These findings emphasize the importance of the ACTH-response test in the diagnostic evaluation of dogs with clinicopathologic findings similar to those of hypoadrenocorticism.  相似文献   

Eye diseases in Siberian husky dogs     

RG STANLEY  JR BLOGG 《Australian veterinary journal》1991,68(5):161-162

A full ophthalmic examination was performed on 40 Siberian husky dogs using direct and indirect ophthalmoscopy, gonloscopy and nasolacrimal cannulation. Eight (20%) of the dogs were found to have distichia, 10 (25%) had excessive medial caruncular hairs, 8 (20%) had absence, displacement, or narrowing of the nasolacrimal puncta, 2 (5%) had bilateral corneal crystalline opacities, and 2 (5%) had unilateral areas of lateral corneal lipidosis. Fifty percent of the dogs had some abnormality of the iridocorneal (drainage) angle. However, in only one of these was the deformity severe enough to require glaucoma prophylaxis. An association between blue iris colour and malformation of the iridocorneal angle was noted.  相似文献   

"Coulomb Staircase" at Room Temperature in a Self-Assembled Molecular Nanostructure     

RP Andres  T Bein  M Dorogi  S Feng  JI Henderson  CP Kubiak  W Mahoney  RG Osifchin  R Reifenberger 《Science (New York, N.Y.)》1996,272(5266):1323-1325

Double-ended aryl dithiols [alpha,alpha'-xylyldithiol (XYL) and 4,4'-biphenyldithiol] formed self-assembled monolayers (SAMs) on gold(111) substrates and were used to tether nanometer-sized gold clusters deposited from a cluster beam. An ultrahigh-vacuum scanning tunneling microscope was used to image these nanostructures and to measure their current-voltage characteristics as a function of the separation between the probe tip and the metal cluster. At room temperature, when the tip was positioned over a cluster bonded to the XYL SAM, the current-voltage data showed "Coulomb staircase" behavior. These data are in good agreement with semiclassical predictions for correlated single-electron tunneling and permit estimation of the electrical resistance of a single XYL molecule (approximately18 ± 12 megohms).  相似文献   

Effect of lenperone hydrochloride on gastroesophageal sphincter pressure in healthy dogs.          下载免费PDF全文

S E Johnson  A Zelner    R G Sherding 《Canadian journal of veterinary research》1989,53(2):248-250

Treatment of healthy dogs with the butyrophenone derivative, lenperone hydrochloride, at two different doses significantly decreased gastroesophageal sphincter pressure (GESP). No dose-related effect was identified. Individual variation in the response to lenperone hydrochloride was noted which was consistent on a day-to-day basis. Lenperone hydrochloride is unsuitable for chemical restraint of dogs undergoing esophageal manometry because it decreases GESP and because the magnitude of the decrease varies considerably between dogs.  相似文献   

Bone marrow hypoplasia in eight dogs with Sertoli cell tumor   总被引：1，自引：0，他引：1  

R G Sherding  G P Wilson  G J Kociba 《Journal of the American Veterinary Medical Association》1981,178(5):497-501

Eight male dogs with Sertoli cell tumor had pancytopenia and bone marrow hypoplasia attributed to endogenous estrogen myelotoxicosis. Clinical signs were hemorrhage caused by thrombocytopenia, anemia caused by blood loss or diminished erythrocyte production, and infection and fever associated with granulocytopenia. Other signs attributed to hyperestrogenism were feminization and prostatic disease. Two dogs recovered after castration and supportive treatment, but 5 other similarly treated dogs died of hematopoietic failure. One dog was euthanatized.  相似文献

Ordering of ruthenium cluster carbonyls in mesoporous silica     

W Zhou  JM Thomas  DS Shephard  BFG Johnson  D Ozkaya  T Maschmeyer  RG Bell  Q Ge 《Science (New York, N.Y.)》1998,280(5364):705-708

The anionic ruthenium cluster carbonylates [Ru6C(CO)16]2- or [H2Ru10(CO)25]2- interspersed with bis(triphenylphosphino)iminium counterions (PPN+) are incorporated from solution into the pores of MCM-41 mesoporous silica (3 nanometers in diameter), where they form tightly packed arrays. These arrays were shown by high-resolution transmission electron microscopy, Fourier transform optical diffraction, and computer simulations to be well ordered both along and perpendicular to the axis of the cylindrical pores. In their denuded state produced by gentle thermolysis, the cluster carbonylates yield nanoparticles of ruthenium that are less well ordered than their assimilated precursors but show good activity as hydrogenation catalysts for hexene and cyclooctene. In both their as-prepared and denuded states, these encapsulated clusters are likely to exhibit interesting electronic and other properties.  相似文献
