  • Cattle in Alaska seemed to be tolerant to low blood selenium (Se) although arctic winter energy demands might exacerbate oxidative damage to tissues lacking protection by Se. The thermogenic properities of brown adipose tissue (BAT) and the long cold adaptation period for Alaskan cattle indicates that they might develop BAT. Eighteen mature beef cows with whole blood Se of< 19 ppb were used to examine possible relation-ships among Se deficiency, tissue lesions, and observable BAT. All cows were wintered on a diet low in Se and nine cows were given supplemental Se provided by intraruminal bolus. Blood Se was elevated (p < .05) from November through February by supplemental Se, but body weight and back fat thickness were unaffected (p < .10). Tissues were taken from two Se deficient cows, two cows supplemented with Se, and two cows given large doses of Se (300 mg by injection) four weeks before slaughter. Histopathological examination of 187 samples of fat (7 to 55 from each cow) showed no observable amount of BAT. Examination of other tissues showed no lesions attributable to Se deficiency.

  • An 8-month-old, intact male Maltese dog was referred to us because of anorexia, diarrhea, and jaundice. Hematologic examination revealed immune-mediated hemolytic anemia, and abdominal ultrasonography revealed heterogeneous changes in mesenteric fat and coarse echotexture in the splenic parenchyma. Septic peritonitis was diagnosed on the basis of a bacterial culture test of the peritoneal fluid. Exploratory laparotomy and subsequent omental biopsy and splenectomy were performed. On histopathological examination, the omental mass and splenic lesions were diagnosed as grain foreign body granulomas. This report describes a rare case in which a grain foreign body was embedded in the spleen of a dog.

  • We report a rare case of primary intradural extramedullary myxopapillary ependymoma of the spinal cord. A 45-year-old woman was admitted to the author's institution with a history of progressive paraparesis[grade IV/IV] with back pain. Neurologic examination revealed decreased sensation below T12 sensory dermatome level. Magnetic resonance imaging[MRI] revealed an intermediate enhanced intradural extramedullary tumor extending from T12. Total resection of the tumor was achieved by T12 laminectomy. Intraoperatively, there was no finding of attachment to rootlet and dura. Histopathological examination identified the tumor as a myxopaillary ependymoma. To the best of my knowledge, this is the first reported case of primary intradural extramedullary ependymoma in Korea.

  • Dentigerous cysts are the most common developmental cysts of the jaws, most frequently associated with impacted mandibular third molar teeth. Dentigerous cysts around supernumerary teeth, however, account for 5% of all dentigerous cysts, with most developing around a mesiodens in the anterior maxilla. This report describes two cases of a dentigerous cyst associated with an impacted mesiodens. Both of the patients complained of swelling in the maxillary anterior region. Radiographic examination revealed an impacted mesiodens surrounded by a large corticated radiolucency in both cases. A provisional diagnosis of infected odontogenic cyst was made. The cysts were enucleated with the removal of the mesiodens in the two cases. Histopathological examination confirmed the diagnosis of infected dentigerous cyst associated with an impacted mesiodens in both cases. The patients remained asymptomatic, and no complications were noted.

  • Lymphangioma(or cystic hygroma) of the chest wall is rare case. We experienced one such case in a 16-year-old girl who complained of a large recurrent mass on her right upper post erolateral chest wall which had developed several years ago. The diagnosis was made following a physical examination, chest magnetic resonance imaging(MRI), and radio isotope (RI) lymphangiogrphy and was confirmed by a histopathological examination. We performed total excision of the lesion followed by a repeated sclerosing therapy with intralesional injection of Vibramycin.

  • This study was carried out to investigate the four-week oral toxicity of the CH-50002 (Vibril vaccine) in beagle dogs. The beagle dogs were orally administered for 28 days, with dosage of 0.5, 5, 50 mg/kg/day, respectively. Animals treated with CJ-50002(Vibrio Vaccine) did not cause any death and show any clinical signs. There were not significantly different from the control group in urinalysis, ocular examination, hematological, serum biochemical value and histopathological examination. Therefore, CJ-50002(Vibrio Vaccine) was not indicated to have any toxic efent in the beagle dogs, when ti was orally administered below the dosage 50mg/kg/day for rour weeks.

  • A 49-year-old woman presented with headache, vomiting and visual disturbance. Neurological examination revealed bitemporal hemianopsia with poor visual acuity. Magnetic resonance imaging showed a bulky intra-suprasellar mass, which was isointense with brain parenchyma on T1-weighted images, and slightly hyperintense on T2-weighted images. After gadolinium administration, the mass was homogeneously enhanced. The mass was partially removed by the endonasal transsphenoidal approach and then the remnant mass was totally removed by the transcranial approach five months later. We found a yellowish mass which was attached to the diaphragm sellae in operation field. Histopathological examination of the tumor revealed the characteristic features of a schwannoma. We report an unusual case of an intra-suprasellar schwannoma resembling a non-functioning pituitary macroadenoma both clinically and radiologically.

  • An eight-year old neutered male miniature pinscher dog was referred with a mass on the right frontal region. Radiography, computed tomography (CT) and magnetic resonance imaging (MRI) examination were performed. Imaging results showed mineralized mass invaded frontal bone without brain parenchymal change and distant metastasis. The mass was removed mostly by surgical resection, and the dog was discharged without any complications. On the histopathological examination, the mass was diagnosed as grade I multilobular osteochondrosarcoma. Though the mass recurred after the surgical resection, the dog is still alive to date without metastasis.

  • We report a pediatric patient admitted with abdominal pain, diffuse lower extremity edema and watery diarrhea for two months. Laboratory findings including complete blood count, serum albumin, lipid and immunoglobulin levels were compatible with protein losing enteropathy. Colonoscopic examination revealed diffuse ulcers with smooth raised edge (like "punched out holes") in the colon and terminal ileum. Histopathological examination showed active colitis, ulcerations and inclusion bodies. Immunostaining for cytomegalovirus was positive. Despite supportive management, antiviral therapy, the clinical condition of the patient worsened and developed disseminated cytomegalovirus infection and the patient died. Protein losing enteropathy and disseminated cytomegalovirus infection a presenting of feature in steroid-naive patient with inflammatory bowel disease is very rare. Hypogammaglobulinemia associated with protein losing enteropathy in Crohn's disease may predispose the cytomegalovirus infection in previously healthy children.

  • A 6-year-old female, shih-tzu was presented in the February with bilateral, symmetrical hair loss and hyperpigmentation on caudal dorsolumbar region. Skin test and blood examination found no remarkable finding. Histopathological examination of biopsies from the alopecic lesions revealed follicular atrophy, infundibular hyperkeratosis and some follicles were twisted truncated and dilated. The diagnosis of recurrent flank alopecia was based on clinical signs and supportive histopathology. Treatment with oral melatonin was started at 3 mg twice daily for 80 days, and by this time complete hair regrowth was observed. The following year in the September, a small non-inflammatory alopecia developed in the same site. The dog was given oral melatonin at 3 mg twice daily for 4 weeks, hair had completely regrown.
