2개월령 수컷 핏불테리어종 개 (체중 1.01 kg)가 심한 복부 팽만, 운동 불내성, 성장 지연, 노란 비루와 식욕부진을 주증으로 진료 의뢰 되었다. 영상 진단상에 비정상적인 막으로 분할된 확대된 우심방, 심한 수축기 폐동맥 제트 혈류 (최고혈류 5.66 m/s) 그리고 심방 중격에서의 우좌 단락혈류가 관찰되었다. 임상증상 및 진단학적 결과에 기초하여, 본 증례는 심한 폐동맥 협착과 우좌 단락의 난원공 개존증이 합병된 우측 삼중심방증으로 진단 되었다. 비안정적인 환자의 상태 때문에 수술적 혹은 중재적 치료는 시도되지 않았다. 그 개는 수혈, 산소공급 그리고 심장 관련 약물적 치료(예, 실데나필, 스피로노락톤, 에날라프릴)로 회복되었다.

The present study was conducted to determine the effect of cold stress on broiler performance and ascites susceptibility. Male chicks were obtained from a commercial strain of broiler breeders. The trial was divided into two treatments (control and cold stress groups). Ascites was induced in broiler chickens in the trial by exposing the chickens to low temperature (Ta) and by supplying a pelleted diet. The two experimental treatments consisted of: 1) Control group, $33.3^{\circ}C$ the $1^{st}$ wk, $30.2^{\circ}C$ the $2^{nd}$ wk, and $27.5^{\circ}C$ the $3^{rd}$ wk. 2) Cold stress group, $29.0^{\circ}C$ the $1^{st}$ wk, $26.4^{\circ}C$ the $2^{nd}$ wk, and $23.1^{\circ}C$ the $3^{rd}$ wk. From the end of the $3^{rd}$ wk all broilers were reared to 6 wk of age at a constant temperature of $21^{\circ}C$. There was significant difference in live BW during wk 1 to 5. The control group was consistently the heaviest; however, at 6 wk of age, both groups weighed the same. Body weight gain up to 3 wk was significantly decreased by cold stress. During wk 3 and 6 the chicks in the cold stress group had greater BW gain compared with the chicks in the control group. There were significant differences in mortality due to ascites between the groups. During wk 3 and 6 the cold stress group exhibited the most ascites mortality (9.52%) when compared with the control group (1.90%). At 5 wk of age cold stress condition caused significant changes in packed cell volume (PCV), hemoglobin (Hb) and red blood cell counts (RBC). Right ventricle weight was significantly heavier in the cold stress group than the control. There were also significant differences in right ventricle/total ventricle (RV/TV) ratios at 5 wk. the right ventricle/total ventricle ratios in the cold stress group was higher (0.25) than the control group (0.20). It was concluded that, fast growth and cold temperatures are the primary triggers for ascites during commercial broiler production.

A two-year-old spayed female Maltipoo dog was presented with a two-month duration of glaucoma in the right eye. On the first presentation, menace response and dazzle reflex were absent in the right eye, but it was present in the left eye. Slit-lamp biomicroscopy showed buphthalmia, mild corneal edema, and conjunctival and episcleral hyperemia in the right eye. The intraocular pressures were 70 mmHg and 30 mmHg in the right and left eyes, respectively. On the gonioscopic and high-resolution ultrasound examinations, both the iridocorneal angle and ciliary cleft were completely closed in the right eye. However, gonioscopy revealed an opened iridocorneal angle even with some broader base of pectinate ligament fiber, but high-resolution ultrasound showed a narrowed ciliary cleft and increased contact of the iris base with the limbal cornea in the left eye. Based on these results, a diagnosis of primary angle-closure glaucoma was made in both eyes. This case report highlighted the importance of evaluating the ciliary cleft with high-resolution ultrasound as a critical diagnostic and prognostic role in canine glaucoma.

규범적 표상은 단어나 주제가 주어졌을 때 자연스럽게 떠오르는 심상이다. 이러한 규범적 표상은 대상의 특징을 가장 잘 드러낼 수 있는 특정한 조망이나 방향으로 떠오르게 된다. 규범적 표상이 측면임을 시사하는 선행 연구를 바탕으로 본 연구에서는 규범적 표상의 방향성을 검토하였다. 규범적 표상을 자연범주와 인공범주로 구분하여 자극의 제시 방향에 따른 차이를 알아보았다. 실험은 그림의 방향성(왼쪽/오른쪽)과 범주(동물, 자연범주/도구, 인공범주)를 두 가지 독립변인으로 하여 설계하였으며 단어-그림 일치 판단과제를 사용하여 정답 반응률과 반응시간을 측정하였다. 그 결과, 정답 반응률은 범주 내에서 방향성에 따른 모든 조건에서 천장효과를 보였으며 아주 근소한 차이만 있었다. 반응시간에서 범주변인의 주효과, 범주와 방향성의 상호작용 효과가 나타났다. 특히 자연범주에 속하는 동물 그림에서 방향성 효과가 관찰되었다. 동물의 머리가 왼쪽으로 향하는 그림이 오른쪽으로 향하는 그림 보다 반응시간이 유의하게 빨랐다. 그러나 인공범주에 속하는 도구 그림에서는 방향성의 효과가 나타나지 않았다. 이러한 결과는 동물의 규범적 표상의 방향성은 왼쪽을 향하는 것임을 시사한다.

A 12-year-old castrated male Shih Tzu presented with suspected hearing loss. The patient had no history of head trauma or exposure to ototoxic drugs. The results of neurologic and physical examinations were normal. An otoscopic examination showed that both the tympanic membranes and the external ear canals had a normal appearance. However, the results of brainstem auditory evoked response tests confirmed sensorineural deafness in the right ear and indicated conduction disturbances and brainstem abnormalities in the left ear. Magnetic resonance imaging was performed to confirm the causes of the conduction disturbances and brainstem abnormalities. Inflammatory changes in the left middle ear were highly suspected to be responsible for the findings in the left ear. The results of these examinations confirmed complete hearing loss in the right ear and indicated otitis media in the left ear, which could have been the cause of the conduction disturbances.

The change in the position of the abdominal organs due to movement by respiration is one of the reasons behind inaccurate irradiation of organs during radiotherapy (RT). Although studies in human medicine have revealed on the respiratory movements of abdominal organs, there is little information and no reference data for dogs. The purpose of this study was to establish the reference values of abdominal organs movement in various postures using computed tomography (CT), and to compare the movements of organs between dorsal recumbency and ventral, right and left lateral recumbency during respiration. CT images for kidney, adrenal gland, medial iliac lymph node, urinary bladder, gallbladder, liver, stomach, and thoracic and lumbar vertebral body of five beagle dogs were acquired. The movements of organs were evaluated by comparing the end-expiratory and end-inspiratory images. Movements of the organs were evaluated by dividing it into right-to-left, dorsal-to-ventral, and cranial-to-caudal directions. The movements of abdominal organs according to the change in postures and respiration were establish. The movement of the bilateral organs was the least when the organs were in the downward position (p < 0.017). The movement of cranial-to-caudal direction was greater than the movement of the other directions in most of the organs. Data obtained in this study may be useful in selecting the appropriate posture that can reduce the movements of organs to be treated with RT, and the data could be useful for setting the planning target volume to consider the movements of the abdominal organs by respiration.

The aim of this experiment was to evaluate the levels of hormones (progesterone, IGF-I and IGFBP-3) in blood plasma, growth, carcass traits and their interactions of sexually immature (n = 18) and sexually mature (n = 17) gilts. To calculate average daily weight gain (ADG), gilts were individually weighed at the beginning of the trial and at slaughter (110${\pm}$10 days old). Blood concentrations of progesterone, IGF-I and IGFBP-3 were determined by RIA. The right hot carcass sides were dissected and the individual basic parts from carcasses were weighed to record the carcass traits. IGFBP-3, ADG and carcass traits were not affected by pubertal maturation. Compared to sexually immature gilts, mature gilts had higher blood concentrations of progesterone and IGF-I. High correlations were noted between levels of some hormonal substances, productive performance and carcass traits of sexually immature and mature gilts.
