Management of bilateral flexural deformity of the metacarpophalangeal joints in three alpaca crias     

T CASHMAN  AJ DART  A O''SHEA  DR HODGSON 《Australian veterinary journal》1999,77(8):508-510

Three neonatal alpacas were treated for MCP flexural deformities. Two crias responded well to conservative therapy using splints made from fibreglass cast material. One cria with severe deformity failed to respond to conservative treatment but recovered satisfactorily after transection of the suspensory ligament in both legs. It seems that mild cases of flexural deformity of the MCP joint in alpaca crias respond well to conservative therapy but that surgical correction may be required in more severe cases. Sequential transection of the structures limiting extension of the MCP joint may result in fewer complications than previously reported techniques.  相似文献

Flavobacterium psychrophilum is the aetiological agent of rainbow trout fry syndrome and bacterial cold water disease. This study examined the genetic diversity of F. psychrophilum isolates retrieved from multiple epizootics at rainbow trout, Oncorhynchus mykiss, rearing facilities and from spawning coho salmon, O. kisutch. A total of 139 isolates were confirmed as F. psychrophilum by PCR assay and were further typed using pulsed-field gel electrophoresis (PFGE). Multiple epizootics at three proximally located rainbow trout rearing facilities were numerically dominated by three PFGE profiles, which accounted for 76% of all trout isolates. In coho salmon, 19 PFGE profiles were differentiated by PFGE and four numerically dominant PFGE profiles represented 56% of all coho salmon isolates. PFGE analysis also indicated that the average similarity of macrorestriction patterns of F. psychrophilum isolates was greater in rainbow trout than in coho salmon (88% vs. 70%). Furthermore, it was not unusual to isolate multiple PFGE profiles from a single coho salmon sample whereas only two PFGE profiles were shared between two sample dates separated by 1 month. It is clear that the domestic rainbow trout aquaculture facilities studied here were primarily affected by a complex of genetically related strains whereas spawning coho salmon supported a much more genetically diverse collection of F. psychrophilum.  相似文献   

Indices of renal function: values in eight normal foals from birth to 56 days   总被引：1，自引：0，他引：1  

DJ EDWARDS  MA BROWNLOW  DR HUTCHINS 《Australian veterinary journal》1990,67(7):251-254

A series of blood and urine samples was collected from each of eight normal foals between birth and eight weeks. Blood chemistry relating to renal function was evaluated as well as physical and chemical characteristics of urine. During the first 4d of life it was impractical to suggest meaningful normal values due to wide variation among foals and with time. Serum urea and plasma creatinine fell markedly to levels less than those previously reported for normal adult horses, while urine, mildly hypersthenuric at birth, rapidly became hyposthenuric. There was also a marked proteinuria during the first 48h. After 4d clinicopathological values stabilised. Urea and creatinine remained at subadult levels and hyposthenuria was maintained. While there was some variation with time, generally the urinary activity of gamma-glutamyl transpeptidase (GGT) and alkaline phosphatase (AP) was greater in foals than in adults; plasma potassium, the creatinine clearance ratio of potassium (% Cr K), serum inorganic phosphate and the creatinine clearance ratio of phosphate (% Cr PO4) were greater than in adults while plasma chloride and the creatinine clearance ratio of chloride (% Cr Cl) were lower in foals than in adults. Urinary pH was acidic and epithelial cells and calcium oxalate crystals more prevalent in the urine of foals than in that of adults. The information presented here will be useful in the diagnosis and management of renal disease and azotaemia in foals.  相似文献

Evaluation of d,l-ethionine as a mechanism for pancreatic islet regeneration in dogs     

M. GOVENDIR  PJ CANFIELD  DR EMSLIE  ADJ WATSON  DB CHURCH 《Australian veterinary journal》2002,80(1):75-82

Objective To determine whether induction of pancreatic necrosis and islet proliferation by d,l‐ethionine has potential for treating dogs with b ‐cell insufficiency. Design Eighteen mixed breed dogs of both sexes were given d,l‐ethionine at 100 mg/kg three times weekly for 2 weeks; 6 dogs were euthanased at 2, 14 and 28 d after the last dose. Methods Clinical signs during administration and recovery were assessed. Routine biochemical analyses were performed before each ethionine dose and then once weekly. Faecal samples were examined weekly for malassimilated nutrients and blood. Blood coagulation screening tests (OSPT and APTT) were determined on four dogs after ethionine administration. Intravenous glucose tolerance tests were conducted before the first and after the last ethionine dose and then fortnightly. All dogs were necropsied and pancreas, liver, kidney and jejunum were examined microscopically. Results During ethionine administration all animals displayed vomiting, inappetence, diarrhoea (often with blood), weight loss and depression. Three dogs were euthanased prematurely due to severe illness, but those allowed to recover were eating and brighter 7 d after cessation of ethio‐nine administration. Serum concentrations of TLI, amylase and lipase increased initially, then decreased, during administration but returned to normal during recovery. Concentrations of ALT, ALP, unconjugated and conjugated bilirubin increased during administration then decreased slowly. Histological examination revealed hepatic lipidosis and necrosis, but no renal or jejunal lesions. In most dogs, faecal examination demonstrated increased undigested starch and muscle, as well as increased digested and undigested fat, during ethio‐nine administration or early during the recovery period, suggesting transient malassimilation. APTT was unchanged but OSPT was prolonged in all dogs. There was no impairment of insulin secretion or glucose intolerance and C‐peptide concentrations were unaffected. Immediately after ethionine administration there was delayed insulin degradation and by day 43 there was evidence of increased insulin sensitivity. Conclusion d,l‐ethionine administration in dogs appeared not to interfere with insulin secretion, but caused clinical signs and laboratory changes indicative of pancreatic exocrine necrosis, severe hepatobiliary disease and transient malas‐similation. Pancreatic and hepatic dysfunction was severe but clinical recovery occurred after ethionine administration ceased. The severe side‐effects observed with d,l‐ethionine should preclude its potential use for treating diabetes mellitus in dogs.  相似文献

Efficacy of metoclopramide for treatment of ileus in horses following small intestinal surgery: 70 cases (1989–1992)     

AJ DART  JR PEAUROI  DR HODGSON  JR PASCOE 《Australian veterinary journal》1996,74(4):280-284

Summary: In this retrospective study, postoperative ileus was studied in horses having resection of the small intestine followed by a jejunojejunal (n=35) or a jejunocaecal (n=35) anastomosis. Twenty-six horses received no metoclopramide, 27 received metoclopramide as an intermittent intravenous infusion and 17 horses received metoclopramide as a continuous intravenous infusion (0.04 mg/kg/hour). Horses receiving a continuous infusion of metoclopramide had a reduced total volume (P< 0.001), shorter duration (P< 0.001), and a slower rate (P< 0.001) of postoperative gastric reflux, and a shorter postoperative hospital stay (P< 0.01) when compared to horses receiving no metoclopramide and horses receiving metoclopramide as an intermittent infusion. Horses having jejunocaecostomy performed had a larger volume (P< 0.05), longer duration (P< 0.05), and a greater rate (P< 0.05) of postoperative gastric reflux, and a longer postoperative hospital stay (P< 0.001) than horses undergoing jejunojejunostomy. Horses that had an abdominal drain placed during surgery had a longer length of intestine resected (P< 0.05) and a longer postoperative hospital stay (P< 0.05) than horses without an abdominal drain. Horses that died or were euthanased during the postoperative period had a greater total volume (P< 0.05), longer duration (P< 0.05), and greater rate of postoperative gastric reflux (P< 0.01), a longer length of small intestine resected (P< 0.01), and a shorter postoperative hospital stay (P< 0.05) than horses that survived until discharge from the hospital. In a multivariate regression analysis the continuous infusion of metoclopramide was the only variable that contributed significantly to predicting the total volume (P< 0.001; r²= 0.24), duration (P< 0.001; r²= 0.24) and rate (P< 0.001; r²= 0.25) of postoperative gastric reflux. We concluded that metoclopramide given as a continuous intravenous infusion decreased the incidence and severity of ileus following small intestinal resection and anastomosis in horses.  相似文献
