임상적으로 건강한 진도개 203두의 혈액치(血液値)를 조사(調査)하였다. 203두에는 암수가 다 포함되어 있었으며 개의 연령은 3개월에서 10세까지 이었다. 적혈구수(赤血球數), 혈색소량(血色素量), 적혈구용적(赤血球容積) 그리고 호산구수(好酸球數) 등은 개의 연령과 함께 증가하였다. 진도개에서 나타난 높은 호산구수(好酸球數)는 심장사상충증(心臟絲狀蟲症)과 벼룩의 감염에 의한 피부염(皮膚炎)때문인 것으로 생각된다.

Lack of hygiene and puerperal mastitis are common causes of bacterial diseases in nursing neonates. The aim of this study was to isolate microorganisms from milk samples of healthy female Jindo dogs with suckling puppies and to investigate antimicrobial susceptibility against the isolated bacteria. Milk samples were collected from 120 udders of 12 lactating Jindo dogs that were 2~4 years old without any clinical diseases including mastitis. Bacteria were isolated from 64 milk samples (53.3%), either singly (76.6%) or in combination (23.4%). Staphylococcus (S.) spp. was the most common microorganisms (74.7%) isolated from canine milk, followed by Haemophillus spp. (10.9%), Streptococcus spp. (9.6%), Gardnerella spp. (2.4%) and Moraxella spp. (2.4%). The most frequently isolated organism was S. warneri (31.3%). Antimicrobial susceptibility of these bacteria was tested with 17 antimicrobial agents by Kirbyand Bauer standardized disc diffusion method. Results indicated that bacteria isolated from healthy canine milk were mostly susceptible to amoxicillin-clavulanic acid, cephalothin and ceftiofur, but were resistant to erythromycin, neomycin and tetracycline.

본 연구는 진도개 동결정액 제조기술을 정립하기 위하여 진도개 정액성상과 동결 전후 정액의 활력과 생존율 및 CASAs를 이용한 운동성 등에 대하여 조사하였고, 백구와 황구간, 개체간의 정액성상과 내동성을 비교, 조사하였다. 이상의 연구결과는 다음과 같다. 1. 총 63회 정액채취 후 신선정액의 평균 정액량 3.8 $m\ell$, 농도 145.6$\times$$10^{6}$$m\ell$, 총정자수 396.2$\times$08/$m\ell$, 전진운동율 79.7% 및 생존율 89.5% 였다. 황구와 백구간에는 황구가, 개체간에는 황구 2호가 정자농도, 총정자수, 전진운동정자율 및 생존율 등의 정액성상에서 유의적으로 우수하였다(P<0.05). 2. 동결전.후 정자의 전진운동율과 생존율을 46회 조사한 결과 동결전 73.5%와 82.3%를, 동결후 51.1%와 64.9%를 나타내 동결과정이 전진운동율과 생존율에 영향이 있었으며, 역시 황구와 백구간에는 황구가, 개체간에는 황구 2호가 동결전후 전진운동율과 생존율에서 유의적인 차이가 인정되었다 (P<0.05). 3. 동결.융해정자의 보다 객관적인 평가를 위하여 CASA system을 이용한 총 44회 평가한 결과, 생존율 65.6%, 전진운동율 54.8%, VAP 75.3 $\mu\textrm{m}$/sec, VCL 90.0 $\mu\textrm{m}$/sec, VSL 69.4 $\mu\textrm{m}$/sec 및 ALH 4.4 $\mu\textrm{m}$로 동결 융해 정액의 운동성은 양호하였고, 황구와 백구간의 운동성에는 유의적인 차이가 없었으나, 개체간에는 역시 황구 2호가 운동성이 우수하여 유의적인 차이가 인정되었다 (P<0.05). 4. 채취된 정액중 백구는 46%(13/28), 황구는 94%(33/35)가 동결정액 제조가 가능해 황구가 내동성이 좋았으며, 전체적으로 73%(46/63) 동결정액 제조가 가능하였다. 결론적으로 진도개의 동결정액을 제조하기 위하여 정액성상 및 동결 전후 운동성을 조사한 결과 동결정액 제조와 생산체계의 구축이 가능하였으며, 황구와 백구간, 개체간의 정액성상과 동결전후의 운동성에 차이가 인정되므로 정액성상과 내동성을 고려한 종견선발 체계가 필요하다고 사려되었다.

This study was performed to develop ethogram of the Jindo dog's temperament categories under various conditions. A set of 12 behavioral tests were developed to investigate temperament categories expressed by the dogs. Fourty-three adult Jindo dogs(24 males, 19 females) from three different farms located in Jindo island were tested in 12 different behavioral tests. All test procedures and dog's behaviors responded to the tests were recorded using two digital video cameras and one digital still camera. A single observer reviewed all of the videotapes focused on dog's vocalization, movement, head, ears, eyes, mouth, and tail-positions. After all of the behavioral variables expressed throughout the testing period were described in detail, an ethogram of four temperament categories of 'sociability', 'aggression', 'fearfulness', and 'submission' revealed by 12 behavioral tests was developed.

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.

개의 성격형질의 연구는 애견가들이 자신의 애견을 잘 이해할 수 있도록 하고, 나아가 만약 탐지견이나 안내견 같은 인간의 생활에 도움을 주는 우수견 선발에 활용될 수 있다. 본 연구에서 우리는 진도개가 가지는 성격적인 형질을 54두의 진도개를 대상으로 조사하였다. 진도개의 공격성과 사교성에 관련하는 10개의 성격문항이 견주들에 의해 채점되었으며, 점수들을 주성분분석법(Principle Component Analysis)을 통해 분석하였다. 나이, 성별, 거주지(진도군 내 또는 외) 그리고 모색(황색 또는 백색)들이 성격특성에 영향을 미칠 수 있는 변수라 판단되어, 진도개 성격 설문문항들에 대해 주성분분석 결과, 세 개의 인자가 추출되었다. 세 개의 인자는 각각 ‘공격성’, ‘unknown factor’, 그리고 ‘사교성’에 관련하는 문항들을 포함 하고 있었다. 위에서 언급한 네 가지 변수와 공격성 간에 상관성은 관찰되지 않았으나(Ps> 0.05), 모색과 사교성 사이에는 황구가 백구에 비해서 사교성이 높은 경향을 보여주었다 (F1,52 =3.213, p=0.079). 공격성이 다른 변수들과는 상관성이 적은 것으로 보아 이후 진도개의 공격성에 대한 유전학적인 연구가 가능할 것으로 사료된다.

This investigation was conducted on 249 Jindo dogs aging from 2 to 12 months to determine body type and external appearance of the dogs. The results of this investigation were as follows. 1. The withers height of male dogs growed rapidly during the period between 2 months and 7 months of age, and was 22.94cm and 49.77cm, respectively. Afterward the growth rate slowed down up to 12 months, 53.33cm. The growth rate of female was similar to male, and the withers height was 22.91cm, 46.81cm, 48.70cm at 2, 6 and 12 months of age. 2. For male and female the body length was 27.21, 27.23cm at 2 months, 51.40cm, 51.62cm at 6 months, 58.33, 52.15cm at 12 months, respectively. Growth rate of the body length was very rapid from 2 to 6 months of age, but afterwards the growth rate was slow and somewhat retarded. 3. For male and female, the withers height to body length ratio was 100 : 109.4 and 100 : 107.1 in 12 months old group. 4. Cross over between the sexes in growth rate occurred between 5.3 to 6.5 months of age for wither height, between 6.0 to 7.2 months for hody length, respectively. 5. The average chest girths of male and female were 31.46, 30.46cm at 2 months, 54.92, 52.20cm at 7months, 60.25, 57.90cm at 12months, respectively. The growth rate of chest girth was rapid between 2 to 7 months of age and gradual between 7 to 12 months. 6. The average skull lengths of male and female were 11.76, 11.32cm at 2 months, 21.83, 19.60cm at 12 months, respectively. The average head widths of male and female were 8.37, 7.94cm at 2 months, 15.47, 12.46cm at 12 months. 7. Erected type of ear was completed from oblique type at 6 months in male and 7 months in female. On our detailed examinations, we concluded that Jindo dogs completed their growth at 6 to 7 months of age.

진도개의 기본체형에 관한 지표를 얻기 위해서 진도군에서 실시한 진도개 심사에 합격되어 전자칩이 삽입된 개를 대상으로 체형을 조사했다. 1998년 8월 현재 총 두수의 약 10%인 195마리의 백구와 황구를 선정하여 개의 기본체형을 가장 잘 표현하는 것으로 생각되는 몸통과 다리의 18개 부위를 측정하였다. 측정결과 중에 중요한 것만을 들자면, 먼저 체고는 수캐 50.67 cm, 암캐 47.48 cm로 수캐가 컸으며 모색에 따른 차이는 없었다. 이어 체장은 수캐 52.99 cm, 암캐 50.33 cm로 역시 수캐가 컸으며 모색에 따른 차이는 없었다. 마지막으로 체고 대 체장 비는 수캐 104.70, 암캐 106.08로 성이나 모색에 따른 차이는 없었다. 이 연구의 결과는 진도개의 보존 및 육성 방향의 지표로 활용될 수 있음은 물론 진도개의 표준화를 위한 형태학적 연구의 자료로도 이용될 수 있으며 아울러 체형의 주기적인 변화를 확인하는 데에도 중요한 자료가 될 것으로 믿는다.
