  • A 10-year-old castrated male Schnauzer (case 1) and a 13-year-old intact male Schnauzer (case 2) was referred with mass of left hind limb. We performed hemogram, serum chemistry, radiography, ultrasonography, computed tomography, fine needle aspiration and histopathology. The complete blood counts and serum biochemistry results were within the reference range. Radiography showed cutaneous mass with soft tissue density. The lesions of two dogs were revealed a definite marginated hyperechoic mass with vascularization in ultrasonography. Computed tomography showed an isodense mass in the left hind limb region with minimal contrast enhancing in case 1 and heterogenous enhancement in case 2. Cytology from ultrasonographic guided aspiration of the mass was suspected fibrous tissue-derived benign cell in two dogs. A surgical excision was performed in two dogs. In histological examination of the resected mass, cutaneous fibroma was revealed. The two patients were successfully treated by surgery and postoperative care. This report decribes and compares radiographic, ultrasonographic, computed tomographic, cytologic and histopathologic features of the cutaneous fibroma of two schnauzer dogs.

  • 10년령의 수컷 푸들이 복부팽만, 등쪽 몸통 부위 탈모, 간비대와 혈청 알칼리인산분해효소의 지속적인 상승으로 전북대학교 수의과대학 동물병원에 내원하였다. 간 생검 및 미세침흡인세포 검사법과 PAS 염색을 실시한 결과 공포성 간병증 및 간세포에 글리코겐이 침착된 것을 확인 하였다. ACTH 자극 시험 실시 전 후 코티솔 및 부신과 관련된 성 호르몬의 농도를 측정하였다. 측정결과 안드로스텐디온, 프로게스테론 및 수산화 프로게스테론의 상승을 관찰할 수 있었으며 코티솔농도는 정상 범위내에 존재하였다. 진단은 성호르몬과 관련된 비정형의 부신피질 기능 항진증으로 내렸으며 치료는 트릴로스탄으로 하였다. 치료 8주 후 등 부위의 탈모를 포함한 임상증상들이 개선되었다.

  • 6 년령의 수컷 시츄 견이 복부 팽만을 주 호소로 내원하였다. 복부 방사선 검사와 초음파 검사에서 많은 양의 액체를 포함하고 있는 연부조직 밀도의 종괴가 발견되었다. 종괴의 세포학적 검사를 위해 초음파 유도 세침흡인을 실시하였으며, 세포학적 검사 결과 섬유화가 동반된 육아조직이 의심되었다. 종괴의 확인과 수술적 제거를 위해 진단적 개복술을 실시하였다. 개복시 원위 공장부위에 인접한 장간막의 뿌리에서 유래한 종괴가 확인되었고 종괴는 원위공장 부위에 부착되어 있었다. 종괴와 부착 부위의 분리가 어려웠기 때문에 종괴와 부착 부위를 모두 수술적으로 제거하였으며 장문합술을 실시하였다. 종괴의 조직병리학적 검사 결과 저 악성도 점액육종이 진단되었으며, 종양 세포는 알시안 블루 염색에 양성 반응을 보였다. 추가로 실시한 Ki67 항체를 이용한 면역조직화학 염색 결과 Ki-67 지수는 2.5 였다. 환축은 절제술 실시 후 현재까지 30개월 동안 전이와 재발의 증거 없이 살고 있다.

  • 프로게스테론 제제를 복용해 오던 12세령의 암컷 잡종 견이 복부 종괴의 평가를 위해 내원하였다. 복부 초음파 검사와 방사선 검사를 통해 확장된 자궁과 관련된 종괴를 확인하였다. 혈청 화학 검사에서는 고글로불린혈증이 나타났으며, 전기영동 검사상 급성 염증 패턴으로 판단되었다. 초음파 유도하에 종괴의 세침흡인을 실시하였으며 세포학검사를 통해 선암종이 진단되었다. 탐색적 개복을 실시하였으며 장구체의 종괴를 발견하여 자궁과 함께 종괴를 제거하는 수술을 실시하였다. 조직병리 검사결과 자궁 선암종이 진단되었으며 종양세포의 에스트로겐 수용체와 프로게스테론 수용체 발현 여부 평가를 위해 면역 염색을 실시하였다. 면역염색결과 종양세포는 두 항체에 대해 음성 결과를 보였으며, 정상 간엽세포에서만 양성 결과가 나타났다. 수술 후 1주일에 재검을 위해 내원하였는데 컴퓨터 단층촬영 검사결과 폐 전이가 확인되었다. 환자는 수술 후 40일경에 폐사하였다.

  • A 1.35 kg, three-year-old, female, Yorkshire terrier was referred to the veterinary medical teaching hospital of Chungnam National University with an alopecia, scale, polydipsia and polyuria. During hospitalization, the patient revealed swelling and pain of all four foot pads. The hematology indicated nonregenerative anemia. Blood serum chemistry revealed elevation of BUN, serum creatinine and phosphorus contents. Radiographs of feet revealed increased radiodensity in the soft tissue of the foot pad. In ultrasonographs of abdomen, kidneys showed diffusely echodense renal cortex with loss of the normal corticomedullary boundary. Fine needle aspiration of the swollen pad cysts contained a amorphous basophillic chalky, white and pasty material. The culture result was negative for bacteria. In conclusion, it was diagnosed as metastatic calcinosis circumscripta secondary to chronic renal failure. An oral charcoal absorbent and aluminum hydroxide were used to treat this condition. After six weeks treatment, hyperphosphatemia was corrected and metastatic calcinosis circumscriptawas not presented any more.

  • Lymphoma is the most common hematopoietic malignancy in dogs. Diagnosis of lymphoma is classically performed by morphological assessment and immunohistochemistry. But some cases in the early stage are difficult to distinguish and need more objective and accurate methods. So, Polymerase chain reaction (PCR) for antigen receptor rearrangements (PARR) and flow cytometric immunophenotype of lymphoma have been developed continuously. In this study, we performed these two methods to classify lymphoma type in 3 cases. According to PARR analysis, B cell origin lymphoma was diagnosed in two of three cases by testing PBMC and lymph node. All fine needle aspiration (FNA) samples of lymph nodes had high expression of CD21 on >88% of total cell population and PBMC samples also showed high expression of CD21 on >30% of total lymphocytes in those two cases, while the expression of CD3, CD4 and CD8 was absent. These results suggest that concurrent use of PARR and flow cytometric immunophenotype is more effective and valuable tool for the diagnosis and monitoring of canine lymphoma patients.

  • 액상 숏크리트 급결제(알칼리 알루미네이트, 2종의 알카리프리)가 시멘트 계의 수화 특성에 미치는 영향을 조사했다. 새로운 알카리프리계 숏크리트용 급결제(AF2)를 적용할 경우 기존의 알칼리 알루미네이트 급결제에 비해 초결, 종결 시간은 단축되었고, 1일 압축 강도는 유사했다. 12시간 경과된 모르타르 시편의 압축 강도는 알칼리 급결제가 첨가된 시편이 가장 높았으나, 이후 최종 강도는 알칼리 급결제를 첨가한 시편이 가장 낮았다. 그러나 알카리프리가 첨가된 AF1, AE2 시편의 압축 강도는 28일까지 plain과 유사했다. XRD와 DSC 분석을 통해 알칼리계 급결제는 주로 수산화칼슘, 알카리프리계 급결제는 에트링자이트 결정 성장으로 응결이 촉진된 것을 확인했다.

  • Hydrothermal deposition of hydroxyapatite coatings on two types of $ZrO_2$ substrates (3 mol% $Y_2O_3$-doped and 13 mol% $CeO_2$-doped tetragonal $ZrO_2s$) was studied using aqueous solutions of $Ca(NO_3)_2\;4H_2O$ and $(NH_4)_2HPO_4$ containing EDTA (ethylene diamine tetra acetic acid) disodium salt as a chelating agent for $Ca^{2+}$ ions. For the precipitation of the coatings, the $EDTA-Ca^{2+}$ chelates were decomposed by oxidation with $H_2O_2$ at $90^{\circ}C$. The deposition behavior, morphology, and orientation of the coatings were investigated while varying the solution pH using scanning electron microscopy and X-ray diffractometry. For the two sub-strates, sparse deposition of the coating was obtained at pH 5.5, whereas a uniform deposition was obtained at pH 7.1, 9.8, and 11.4 with a denser microstructure for the higher pH. The coating consisted of thin needle-like or plate-like crystals ($1-2{\mu}m$ length or diameter) at pH 7.1, but fine rod-like crystals ($1-2{\mu}m$ length, $0.1{\mu}m$ diameter) at pH 9.8 and 11.4. The coatings were $1-3{\mu}m$ thick and showed a preferred orientation of the hydroxyapatite crystals with their c axis (i.e., the elongated direction) perpendicular to the substrate surface especially for pH 9.8 and 11.4.

  • Ultrasound images are noninvasive, can be observed in real time, have no radiation exposure, do not cause pain, and are not restricted in use depending on the patient's prosthetic implant or medical condition. Since the use of ultrasound in the dental field was first applied for tooth preparation in 1957, the use of diagnostic ultrasound for the first time in 1963 has been reported. Currently, it is used in the diagnosis of soft tissue lesions such as malignant tumor or salivary gland disease, fine needle aspiration test, temporomandibular joint disease, lymph node metastasis, measurement of muscle thickness and inflammatory diseases, differentiation of periapical cyst and granulation tissue, measurement of periodontal tissue thickness. The ultrasound image can be visualized in real time. The clinician can explain the structure to the patient while consulting the patient and consult the patient. When injecting the drug into a specific site or aspirating a specific site or substance, So that it can be confirmed and practiced. Recently, ultrasonic equipment specialized in the dental field has been developed and marketed, and it is expected that the use of ultrasonic waves will become active in the dentistry. In the future, development of popular equipment with size and frequency suitable for dental diagnosis and various researches on maxillofacial ultrasonic anatomy. If clinical studies are continuously carried out to demonstrate efficacy, ultrasound is expected to aid in accurate diagnosis and treatment throughout the dentistry.
