Rehabilitation treatments after orthopedic surgery promote postoperative healing in humans. In veterinary medicine, there is increased interest in rehabilitation treatments because they are potentially beneficial to animals in the post-operation period. This study examined the effectiveness of rehabilitation treatment in dogs that underwent orthopedic surgeries, including femoral head & neck ostectomy (FHNO) and medial patellar luxation treatment (MPLT). The group that received the rehabilitation treatment after FHNO (1.88 weeks) showed a significantly shorter recovery length of 6.62 weeks compared to those that did not receive the treatment (8.50 weeks). The other group that received the rehabilitation treatment after MPLT (4.38 weeks) showed a significantly shorter recovery length of 5.01 weeks compared to those that did not receive the treatment (9.39 weeks). For the qualitative evaluation, the types and frequencies of rehabilitation treatments were monitored. The rehabilitation programs used frequently were heat therapy, laser therapy, passive range of motion, exercise therapy, and aquatic therapy. A standard rehabilitation program after hindlimb surgery was suggested based on the quantitative and qualitative investigation. The results add additional evidence that showed the beneficial effects of rehabilitation treatments in dogs.

Transmissible venereal tumor(TVT) is a naturally occurring contagious neoplasm which can be transmitted by mechanical contact during mating in dogs and transplanted as intact viable cells to dogs and other members of canine family such as coyotes, jackals, wolves, and foxes. The incidence of this tumors tends to increase in Korean native Jindo dogs. This is probably due to the high density and unrestrained management system. With time, TVT reaches the maximum size and then tends to regress spontaneously unless individuals are immunologically compromised. It consists of different types of cells depending on the stage. In this study, 10 tumors were selected from Jindo dogs. These were histologically calssified into three stages; progressive, steady-state, and regressive. Mitotic figures were counted, and their histological appearance at each stage is compared with their DNA ploidy. Histologically, 5 tumor cases were calssed as the progressors, 3 cases as the steady-state tumors, and 2 cases as regressors. Progressors were composed of round cells with large nuclei containing conspicuous nucleoli and frequent mitotic figures. A few spindle-shaped cells and inflammatory cells including mainly lymphocytes, a few neutrophils and macrophages were also seen. In the steady-state tumors, there was an increased number of spindle shaped cells and mitotic figures were rare. Six tumors were diploid and four were aneuploid with the variation coefficient of 7.02. Two of five progressive tumors were aneuploid. Two of three steady-state tumors were aneuploid while both tumors at the regressive stage were diploid. Progressive and steady-state tumors had a much larger S/G2M fraction and a higher mitotic index than regressive tumors. Two tumors which persisted for more than one year were aneuploid. These results suggest that the progressive and steady-state tumors had more active cell division than the regressive neoplasms.

임상적으로 건강한 18두의 개에서 선택적인 삽관술을 통해 ethanol과 iohexol 합제 혹은 ethanol과 barium 합제를 이용한 신동맥 색전술을 실시하였다. Iohexol과 ethanol 합제는 1.5, 2.0 및 3.0 ml/kg을 적용하였고 barium과 ethanol 합제는 0.2, 0.4 및 0.8 ml/kg 각각 적용하였다. 검사항목으로 신기능 이상 유무의 판단 척도로서 혈청 BUN과 creatinine을 술전 및 술후 경시적으로 측정하였으며, 배설성 요로조영술을 7일째, 혈관조영술 및 조직병리학적 검사를 14일째 각각 실시하였다. 혈청 BUN 수치와 creatinine 수치는 시술 후 1일째 조영제 주입에 따른 일시적 변화로 다소 상승하였으나 전반적으로 정상 범주에 속하였다. 배설성 요로조영술 및 혈관조영술 결과 iohexol과 ethanol 합제를 사용한 1군에서는 1.5 ml/kg 용량으로 색전되지 않아 시술한 신장이 영상화되었으며 3.0 ml/kg 투여에서는 용량이 과도하여 실험동물이 폐사하였으나 2.0 ml/kg에서는 모두 색전되었다. barium과 ethanol 합제를 사용한 2군에서는 0.2 ml/kg 1두는 색전되지 않아 신장 및 요관이 영상화되었으며 0.8 ml/kg 2두는 용량 과다로 신장 주위에 X-선 비투과성 barium음영이 확인되었다. 그 중 0.4 ml/kg 3두 모두는 색전되어 신장 및 요관이 영상화되지 않았으며 색전 물질이 역류되지 않아 신장 주위에 X-선 비투과성 barium 음영도 확인되지 않았다. 색전술을 실시하고 2주 후에 신장을 적출하여 육안적으로 관찰한 결과 1군과 2군 모두 색전된 신장의 크기는 반대쪽에 비해 그 크기가 감소하였다. 이상의 결과로 iohexol과 ethanol 합제를 사용한 1군에서는 2.0 ml/kg이 barium과 ethanol 합제를 사용한 2군에서는 0.4 ml/kg이 가장 적절하였다. 모든 개는 그 용량에서 만족스런 색전 효과를 나타내었다.

이 논문은 노령견이 필요한 영양을 다루며, 노령견이 필요로 하는 영양평가를 검토하고, 노령화와 관련하여 흔히 발생할 수 있는 영양의 문제점들을 등을 제시하고자 한다. 즉, 이연구의 목표는 노령견의 노령화와 관련된 생리적인 변화, 필수영양소 및 그와 관련된 질병을 탐구하는데 있다. 2002년의 조사에 의하면, 미국에서 기르는 반려견의 30%-40%는 나이가 7세이상이라고 한다. 유렵의 경우 1983년과 1995년을 비교했을 때 나이가 7세이상의 반려견의 수는 약 50% 늘었다고 한다. 2012에 미국에서 실시한 이메일 조사에 의하면, 50,347명의 응답자 중에서 33.2%가 6살-10살의 노령견을 기르고 있으며, 11살이상의 노령견을 기르는 응답자는 14.7%라고 한다. 가정에서 기르는 반려견의 평균수명은 건강관리, 노령화 및 영양에 영향을 받는다. 그리고 견종, 유전, 영양, 환경 등의 요소에 따라서 노령화의 정도가 다르다. 10살이 넘은 많은 반려견들이 활력이 넘치고 건강하다고 할지라도, 대부분의 반려견들은 5세-6세가 되면, 노령화와 관련된 징조를 보이기 시작한다. 여러가지 질병을 치유할 수 있는 의학의 발달과 영양의 발달로 인하여, 반려견의 평균수명은 점점 증가하고 있다. '노령견을 위한 영양의 목표'는 노령견이 건강하고 활력 넘치게 하며, 노령과 관련된 건강상의 문제가 늦게 시작되고, 노령화를 지연시키며, 삶의 질을 향상시키며, 기대수명을 늘리는데 있다. 노령화는 생리적인 변화를 가져온다. 우리가 육안으로 명백하게 느낄 수 있는 변화들은 털의 색깔이 하얗게 변하는 것, 몸의 기력이 떨어는 것, 시각이나 청각 등의 감각기관에 문제가 오는 것 등이 있으며, 표면적으로 느끼기 어려운 변화들은 소화관, 면역시스템, 신장 등 장기와 관련된 생리적인 변화들이다. 반려견이 필요로 하는 영양은 나이에 따라서 다르다. 또한 노령화가 진행됨에 따라서 발생할 수 있는 영양과 관련된 많은 질병들이 있으며, 이러한 질병에는 영양이 매우 중요하다.

This study was conducted to observe the hematological effect of the small dogs when administrated excessive amount of the Korean native chinese chive(Allium tuberosum Rottler) extracts for a short period. In this experiment, clinically healthy dogs(n = 10, average weight = 4.17 kg) were used. They were inserted stomach tube and administrated the extracts(5ml/kg) for 7 days. The followings are the result of this experiment. The red blood cell counts, hemoglobin concentration and mean corpuscular hemoglobin concentration were significantly decreased. (P<0.05) The packed cell volume was slightly decreased. The mean corpuscular volume and methemoglobin concentration were significantly increased.(P<0.05) The white blood cell counts and reduced glutathione were slightly increased. Consequently, We determined that administrated excessive amount of the Korean native chinese chive extracts induced hemolytic anemia.

Blood group determination in dogs is an important factor in transfusion medicine to minimize immediate or delayed adverse reactions after red blood cells transfusion in small animal clinics. Dog erythrocyte antigen (DEA) 1 is the most important blood type due to its high degree of antigenicity causing acute transfusion adverse reactions. The aim of this study was to investigate the prevalence of DEA 1 in various dog breeds in Korea. As a result of testing 592 blood samples from more than 35 dog breeds, DEA 1 blood typing for each breed showed that 57.8% of Malteses, 63.3% of Poodles, 76.2% of Mastiff-like dogs, 72.5% of Pomeranians, 47.7% of Shih Tzus, 70.3% of mixed breeds, 60.0% of Yorkshire Terriers, and 71.4% of Beagles were DEA 1-positive. Miniature Schnauzers and Jindo breeds had a significantly high prevalence (100%) of DEA 1-positive dogs compared to that in other small breed dogs. This is the first report of immunochromatography-detected DEA 1 prevalence in various domestic dog breeds. Although additional studies need clarifying the potential blood transfusion risks in domestic breed dogs with DEA 1, the results of this study may be useful when selecting a blood donor.

본 연구는 최근 국내에서 발생하는 CCV 장염의 역학적 특성을 조사하기 위하여, 2003년 6월부터 2007년 9월까지 전국의 10개 지역 동물병원에서 설사증상을 보이는 381두의 분변 시료를 채취하였으며, 이중 358두는 혈청학적 검사를 위하여 혈청 시료를 채취하였다. 또한 CCV 장염의 발생에 대한 역학적 조사와 CCV 장염에 이환된 환자의 생존에 영향을 미치는 역학적 요인들에 대하여 조사하였다. 설사증상을 보이는 총 381두중 131두(34.4%)가 CCV 장염으로 확진되었으며, 그 중 30.5%의 변에서는 genotype I이 검출되었고 29.0%에서는 genotype II가 검출되었으며 40.5%에서는 genotype I과 II가 혼합 감염되어 있었다. CCV 장염은 6-18주령의 예방접종을 실시하지 않았거나 불완전하게 실시한 개체에서 주로 발생하였다. 주요 임상증상으로 설사, 구토와 식욕 결핍 증상이 대부분의 환축에서 나타났다. CCV에 이환된 환자 중 나이가 많거나 예방접종을 완료했을 경우 생존율이 높았으며(P < 0.05) 식욕 결핍이 없는 개체일수록 생존율이 높게 나타났다(P < 0.01). CCV 장염에 이환된 환자의 대부분은 개 파보바이러스(CPV-2)와 혼합감염되었으나 이로 인한 생존율에서 유의차는 나타나지 않았다. 따라서 국내에서 CCV의 감염은 빈번하게 발생하고 있으며, CCV 장염은 어린 개체에서 설사를 일으키는 중요한 요인 중의 하나로 확인되었으므로 CCV 감염된 집단으로부터 감수성 있는 개체를 분리하고 CCV에 대한 예방접종을 실시할 필요성이 제기되고 있다.

This study was conducted to observe the severity of the disease and pathogenecity of Babesia gibsoni parasite on the splenectomized dogs(SPD) and nonsplenectomized(intact) dogs (NSPD) experimentally infected with B gibsoni. The average prepatent period was 4 days in the SPD and 8 days in the NSPD, respectively. Peak parasitaemia(PE) ranged from 26% to 34% of erythrocytes infected in the SPD and from 4% to 5% in the NSPD. Latent parasitaemia was still detectable 40 days as low as under 1.0% of erythrocytes infected after the initial parasitaemia in the SPD. Blood packed cell volume(PCV) decreased to as little as 6.4% to 6.9% in the SPD. The clinical signs were mild fever and anemia in the NSPD, remissions and exacervations of temperature, intermittent or spike-like increases of temperature, progressive polychromatophilic macrocytic anemia with anisocytosis, icterus, marked loss of appetite, rarely haemoglobinuria, and deep brown-yellowish urine in the SPD. Gross pathologic changes mainly involved slightly enlargement of liver and spleen in the NSPD and marked enlargement of liver in the SPD. Anatomic changes associated with the disease included diffuse periportal and centrilobular hephatitis, and membranoproliferative glomerulonephritis. Hyaline droplets, resulting protein metabolic alterations, were found in the convoluted ephithelium of the kidney. The density of lymphocytes within the liver sinusoids was markedly increased. Aggregates of large monocytes and macrophages were demonstrated in the centrilobular veins of the liver. The density of these cells in the centrilobular veins were greatest in the SPD. The forms of B gibsoni parasite found in the acute stage of SPD were large signet ring form, small signet ring form, pyriform, elongated form, comma form, head-phone form, oval form, peared form, racket-like form, amoeboid form, triangle form, quartered form, dot form, band form and multiple, and rosette form, et al. The severity of the disease and pathogenecity of B gibsoni parasite were mild in the NSPD but fatal in the SPD.

This study was conducted to compare the anesthetic effects of intravenous tiletamine-zolazepam(TZ, 7mg/kg TZ), tiletamine-zolazepam-xylazine(TZX, 7mg/kg TZ and 1.1mg/kg X) and ketamine-xylazine(KX, 10mg/kg K and 1.1mg/kg X). Fifteen mixed-breed healthy dogs($3.5{\pm}1.0kg$) were randomly assigned to the three treatment groups(TZ, TZX, KX) with 5 dogs in each group. The mean surgical anesthesia time was $25.6{\pm}4.2$, $62.6{\pm}6.2$ and $21.0{\pm}3.7$ min in TZ-, TZX- and KX-anesthetized dogs, respectively. The duration of the loss of response to toe-web needle prick and to visceral pain was significantly increased in the TZX group with $40.0{\pm}15.8$ min and $44.0{\pm}5.5$ min, respectively(p<0.01). Heart rate decreased significantly below baseline in TZX and KX groups(p<0.05, p<0.01) whereas it increased above baseline in TZ group. Respiratory rate remained unchanged or increased above baseline in TZ group, but decreased significantly from 10 to 30 min in TZX(p<0.01, p<0.05) and at 10 min in KX group(p<0.05). Body temperature decreased significantly below baseline in all three groups(p<0.01, p<0.05). Hematologic(PCV, RBC, WBC) and serum chemistry values(GOT, GPT, BUN, creatinine, total protein, glucose) were monitored before anesthesia, after recovery from anesthesia and 1, 3 and 7 days postanesthesia. All hematologic values remained generally within normal ranges, and GOT, GPT, BUN, creatinine and total protein values were within normal ranges during the period. Glucose values for TZX and KX groups increased greatly after recovery from anesthesia. We conclude that tiletamine-zolazepam-xylazine provides effective surgical anesthesia in dogs and in many cases may be preferable to conventional ketamine-xylazine regimen.

One hundred twelve domestic dog sera were collected from Kyonggi, Kanngwon, Cholla, and Kyongsang province. All the sera were examined by immunofluorescence antibody test(IFAT) against scrub typhus, murine typhus and spotted fever group rickettsia infection. The antibody prevalence was 5.40%(6/112) against scrub typhus. The sero-prevalence rates of scrub typhus were 16.30%(5/31) in Cholla and 5.90%(1/17)in Kyonggi areas. The prevalence of scrub typhus was higher in older dogs that were 6 years or more. The antibody prevalence was 8.04%(9/112) against murine typhus. The sero-positive rates to murine typhus were 5.88%(1/17) in Kyonggi, 8.33%(2/24) in Kangwon, 9.68%(3/31) in Cholla, and 7.50%(3/40) in Kyongsang areas, respectively. The sero-positive dogs to murine typhus were widely distributed throughout all age groups from 2 months to above 9 years old. The antibody prevalence was 16.96%(19/112) for spotted fever group rickettsial infection. The sero-positive rates of spotted fever group rickettsia were 11.76%(2/17) in Kyonggi, 12.90%(4/31) in Cholla, and 32.50%(13/40) in Kyongsang areas. The sero-positive dogs to spotted fever group rickettsia were observed at all age groups of dog. The sero-positive prevalence between sex showed higher in female than in male except for spotted fever group rickettsia infection.
