The radiographic technique and radiographic and sonographic findings in two green iguanas with egg retention and peritonitis are described. Neither radiography nor ultrasound provided for identification of free eggs within the coelomic structure secondary to presumed oviduct rupture. Gravidity and coelomic effusion were confirmed by both radiography and ultrasound. Radiography and ultrasound are valuable tools in the diagnosis of egg retention and peritonitis in the green iguana.  相似文献

Identification and partial purification of serum growth hormone binding protein in domestic animal species.     

S L Davis  M Graf  C A Morrison  T R Hall  P J Swift 《Journal of animal science》1992,70(3):773-780

The chemical nature and variations in serum concentrations of growth hormone binding protein (GHBP) from humans, rabbits, and rodents have been reported. To date little is known about the GHBP of domestic animals. Therefore, we initiated these studies to determine whether a serum GHBP was present in domestic animals and to purify the binding protein (BP) from serum of selected species. Using a dextran-coated charcoal separation assay, specific growth hormone (GH) binding was demonstrated in ovine, bovine, chicken, human, goose, porcine, and equine serum (listed in sequence from lowest to highest binding). Variation in BP activity was relatively high, both within and between species. Yearling ewes had higher serum GHBP than either prepubertal (4 mo) or older (5 yr) ewes. The GHBP was partially purified from chicken, ovine, and porcine serum using GH affinity chromatography. These BP had high affinity (Ka = 2 x 10(8) to 2 x 10(9) L/mol, depending on species) and low capacity (2 x 10(-10) to 5 x 10(-11) mol/unit of protein) for human GH but showed lower binding affinity for homologous GH (Ka = 2 x 10(7) L/mol). The porcine GHBP had the highest and ovine GHBP the lowest affinity for human GH. Other heterologous somatotropic hormones, ovine placental lactogen, and ovine GH displayed higher binding affinity to chicken and pig BP than the respective homologous hormones. Further chromatographic purification of the porcine GHBP resulted in an additional 1,000-fold purification. The estimated molecular weight of porcine GHBP is 50,000 to 60,000 Da. These results demonstrate that the serum from all domestic species tested contains a specific GH-binding moiety and that under the conditions described here human GH is a more efficient ligand than the homologous hormone.  相似文献

Treatment of Dogs in Hemorrhagic Shock by Intraosseous Infusion of Hypertonic Saline and Dextran   总被引：1，自引：0，他引：1  

E. B. OKRASINSKI DVM    D. J. KRAHWINKEL MS  DVM  Dipiomate ACVS  W. L. SANDERS PhD 《Veterinary surgery : VS》1992,21(1):20-24

Under isoflurane anesthesia, 50% of the calculated blood volume was removed from 11 dogs. After 30 minutes, five dogs were treated with hypertonic saline and dextran (HSD) (5 mL/kg) followed by isotonic saline solution (2 mL/kg) intraosseously. Six dogs (controls) received isotonic saline (7 mL/kg) intraosseously. All treatments were administered through the medullary cavity of the tibia over a 30-minute period. Cardiac output, mean arterial pressure, central venous pressure, packed cell volume, total protein, and blood gases were monitored for 4 hours. Cardiac output, mean arterial pressure, and circulating volume (indicated by packed cell volume and total protein) were significantly improved after administration of HSD. We conclude that intraosseous infusion of HSD is efficacious in treating hemorrhagic shock and believe the technique may prove to be useful in clinical situations when intravenous lines cannot be established rapidly.  相似文献   

SIMULTANEOUS DOUBLE-CONTRAST CYSTOGRAPHY AND CYSTOMETRY IN DOGS     

Mary B.  Mahaffey  DVM  MS  Don L.  Barber  DVM  MS  Jeanne A.  Barsanti  DVM  MS  Wayne A.  Crowell  DVM  PhD 《Veterinary radiology & ultrasound》1984,25(6):254-259

Double-contrast cystograms and cystometrograms were performed simultaneously in each of six male and six female dogs with normal urinalyses. The dogs were sedated with oxymorphone and acepromazine. Detrusor reflex occurred in 11 of 12 dogs. After bladder infusion of 0.88 ml/kg of positive-contrast medium, there was mucosal irregularity in eight of 12 dogs and bladder shape distortion in 12 of 12 dogs. Bladder distortion decreased with progressive infusion of CO₂, and mucosal irregularity was eliminated after infusion of 50–100 ml CO₂. The bladder neck in all dogs was initially located within the pelvic canal. In ten of 12 dogs, the bladder neck was cranially displaced when the bladder was fully distended. Bladder wall thickness was approximately 1 mm circumferentially at all degrees of distention. There was no discernible difference between bladder shape prior to and at initiation of contraction. It was concluded that radiographic determination of a normal urinary bladder can be made without complete bladder distention and that cystograms and cystometrograms can be routinely performed simultaneously in dogs in which both procedures are required.  相似文献   

Thermal Burns in Four Dogs during Anesthesia   总被引：1，自引：0，他引：1  

COLIN I. DUNLOP BVSc  DiplomateACVA    DAVID A. DAUNT DVM  STEVE C. HASKINS DVM  MS  DiplomateACVA 《Veterinary surgery : VS》1989,18(3):242-246

Thermal burns occurred in four anesthetized dogs as a result of using latex surgical gloves filled with warm water to treat hypothermia. The burns were on relatively hairless skin that had been in contact with the gloves. Small containers full of warm water are a relatively inefficient source of heat, but if the temperature of the water exceeds 45 degrees C and the container contacts the animal's skin, thermal injury can result.  相似文献   

FRACTURED SCLERAL OSSICLES IN A RED TAIL HAWK     

Denise M.  Lindley  BS  DVM  John T.  Hathcock  DVM  MS  William W.  Miller  DVM  MS  M. Nina  DiPinto  VMD 《Veterinary radiology & ultrasound》1988,29(5):209-212

Following head trauma, the left globe of a Red Tail Hawk showed demonstrable indentation on palpation. Recurrent anterior chamber collapse and reformation dependent on head position was the most significant clinical finding. A fracture of the scleral ossicles in the caudal portion of the scleral ring was identified in the rostrocaudal radiograph of the skull. Conservative management of the fracture resulted in phthisis bulbi. Fractured scleral ossicles have been shown radiographically in the enucleated globe but have not been previously demonstrated in the eye of the living bird.  相似文献   

COMPUTED TOMOGRAPHIC ANATOMY OF THE DISTAL EXTREMITY OF THE HORSE     

P. Robin  Peterson  DVM  Karl F.  Bowman  DVM  MS 《Veterinary radiology & ultrasound》1988,29(4):147-156

X-ray computed tomography (CT) is an imaging tool that is becoming increasingly available for use in veterinary medicine. Advantages, including depiction of detailed cross-sectional anatomy, improved contrast resolution, and computer reformatting, make it a potentially valuable diagnostic technique. Veterinary application of CT has been primarily limited to use in small animals. Current reports describe the technique for use in the horse, but there are no published studies correlating serial CT images with equine cross-sectional anatomy. A study of the distal extremity of the horse was undertaken to facilitate interpretation of images produced using CT. Transverse CT images of the distal forelimb of equine cadavers were evaluated relative to gross anatomic dissection. Resolution of bone architecture in transverse plane images was satisfactory, but soft-tissue' resolution, although satisfactory for visualization of major structures, was relatively poor, probably due to lack of interposed fat and insufficient differences in physical density and atomic number. Thus it appears in the equine distal limb that CT may be most useful for evaluation of complex bone abnormalities.  相似文献   

Omentum-Enhanced Reconstruction of Chronic Nonhealing Wounds in Cats: Techniques and Clinical Use     

DANIEL J. BROCKMAN BVSc    ANTHONY D. PARDO MS  DVM  Diplomate ACVS    MICHAEL G. CONZEMIUS DVM    LORI M. CABELL DVM  NICHOLAS J. TROUT BA  VetMB 《Veterinary surgery : VS》1996,25(2):99-104

The greater omentum was used to aid in the reconstruction of nonhealing wounds in five cats. In each cat the cause of the nonhealing wound could not be determined. A vascular omental pedicle was created at laparotomy by dividing the dorsal leaf of the omentum at its pancreatic attachments (four cats) or by dividing the ventral leaf at its gastric attachments (one cat). The pedicle was then passed through either the ventral or lateral body wall into the nonhealing wound via a subcutaneous tunnel. The wounds were closed over the omentum after local tissue mobilization. All the wounds healed uneventfully and have remained healed with a mean follow-up period of 2.5 years. Complications included intestinal herniation through a ventral midline exit hole (one cat), presumed abdominal fat herniation through a ventral abdominal exit hole (one cat) and seroma formation (one cat). All of the complications were treated successfully. The omentum should be considered a useful adjunct in the treatment of nonhealing wounds in cats.  相似文献
