To reduce swine production costs, a slaughter check system has been developed in countries with an advanced swine industry. Evaluation of lung lesions in carcasses is a critical part of the slaughter check system. This study was performed to collect background information for use in developing a slaughter check system in Korea. Lung tissues and their gross images were collected from slaughterhouses in Gyeonggi-do, Korea. Scoring of the gross lung lesions was performed on the lung images. Histopathologic examination was conducted to classify the pulmonary lesions as bronchopneumonia or interstitial pneumonia. Scores of the gross lung lesions were significantly different between bronchopneumonia and interstitial pneumonia groups (p < 0.001). A 90% confidence interval of gross lung lesion scores was established for the bronchopneumonia group, and the lesion scoring had a sensitivity of 100% and specificity of 77.3%. The gross lung lesion scoring test was subjected to a diagnostic distinction evaluation by examining the receiver operating characteristic curve and was appraised as having good discrimination for bronchopneumonia. Establishment of a gross lung lesion scoring test for the diagnosis of bronchopneumonia could be valuable as a screening test of macroscopic bronchopneumonia in swine slaughter check system.

A seven-month-old Hanwoo steer was presented immediately after transport with respiratory symptoms including a nasal discharge, depression, and anorexia. Though repeated treatments, bronchopneumonia had not been improved and had persisted for 10 months. Then, obstructive breath sound was heard. A cyst adjacent to the epiglottis could be observed with respiratory endoscopy. Consequently, chronic bronchopneumonia induced laryngeal cyst formation, resulting in obstructive dyspnea. And respiratory endoscopy may be useful for differentiating the causes of dyspnea in bovine clinical practice.

Peumonia is the infection of the lungs. Bronchopneumonia is the infection of the bronchus. But their symtoms are simillar. I took care of a patient in bronchopneumonia. And then I reviewed Haemophilus influenzae and Soeumin's cough through west-east medicine books. Cough is divided with the outter disease and the inner disease on the pathology of the Korean Medicine(Sansang Constitutional Medicine). And the outter disease is divided with the outter symptom and the inner symptom. The inner disease is divided too. I wanted to discuss Soeumin's cough is the outter symptom of the outter disease and the inner disease. Finally the outter symptom of the outter disease must be applied with the thrapeutic method of the removal wind-cold and the elevation of YangGi in Soeumin's cough. And the outter symptom of the inner disease must be applied with the thrapeutic method of the heating AbdominalGi and the going down of EumGi in Soeumin's cough.

목 적 : 세기관지염과 기관지 폐렴은 흉부 X-선 사진으로 감별되며 세기관지염은 과팽창(hyperinflation)이 중요한 소견으로서 이는 기관지 천식의 흉부 X-선 사진 소견과 유사하다. 세기관지염에 이환된 환아는 향후 기관지 천식을 앓을 가능성이 높다. 기관지 천식은 Th1보다는 Th2와 호산구 활성에 의하여 유발되며, 이러한 Th2와 호산구 활성에 의한 영아의 하기도 질환은 그렇지 않은 하기도 질환보다 향후 기관지 천식으로 이행될 가능성이 높다고 할 수 있다. 본 연구는 영아의 세기관지염과 기관지 폐렴에서 Th1과 Th2 cytokine인 $IFN-{\gamma}$와 IL-5 그리고 호산구 활성의 지표인 Eosinophil cationic protein(ECP)를 관찰하여 세기관지염과 기관지 폐렴간의 면역 병태 생리에 차이가 있는지 여부를 알아봄으로써 영아 하기도 질환의 흉부 X-선 사진상의 차이가 향후 예후를 예측할 수 있는 지표로서 유용한지를 알아보고자 한다. 방 법 : 2세 미만의 영아로서 흉부 X-선 사진상 세기관지염 그리고 기관지 폐렴 환아 21명을 실험군으로, 호흡기 바이러스 감염의 증거가 없는 영아 16명을 대조군으로 하여 각각의 혈청에서 $IFN-{\gamma}$와 IL-5 그리고 호산구 활성의 지표인 ECP치를 측정 비교 관찰하였다. 결 과 : 1) IL-5치는 대조군보다 세기관지염과 기관지 폐렴에서 통계적으로 유의하게 증가되어 있었으나(P=0.02, P=0.042) 세기관지염과 기관지 폐렴간에는 각 군에서 유의한 차이가 없었다. 2) $IFN-{\gamma}$치는 대조군보다 세기관지염과 기관지 폐렴에서 증가되어 있었으나 통계적으로 유의하지 않았으며 또한 기관지 폐렴에서 세기관지염에서보다 증가되어 있었으나 역시 유의하지는 않았다. 3) ECP치는 세기관지염에만 대조군에 비해 유의하게 증가된 ECP치를 관찰할 수 있었다. 4) 세기관지염과 기관지 폐렴 모두에서도 IL-5와 ECP간에 유의한 상관관계를 찾을 수 없었다. 결 론 : 영아 하기도 질환 환아의 혈청에서 대조군에 비해 증가된 알레르기 염증지표(IL-5, ECP)를 관찰할 수 있었으나 세기관지염과 기관지 폐렴간에는 의미 있는 차이가 뚜렷하지 않았다. 또한 세기관지염과 기관지 폐렴간에 IL-5와 $IFN-{\gamma}$의 유의한 차이를 관찰할 수 없어 이 두 질환의 면역 병태 생리에 Th1, Th2 림프구의 선별적 관여를 증명할 수 없었다. 결론적으로 세기관지염과 기관지 폐렴간의 흉부 X-선 사진 양상의 차이가 호흡기 바이러스 감염에 의한 영아 하기도 질환이 향후 기관지 천식으로 이행하는지 여부를 예측할 수 있는 지표로서 유용한 것 같지 않았다.

A 7-year old Holstein bull showing marked thickening of left forelimb was diagnosed as pulmonary hypertrophic osteoarthropathy on the histological basis of the exostotic bone of left metacarphus. Thickening of the bone was due to apposition of excessive cancerous bone beneath the periosteum on the shaft. The lung lesion of the bull, chronic suppurative bronchopneumonia was possibly related to pathogenesis of the bone thickening.

Background: Clinical differences in Mycoplasma pneumonia (MP) in children and adolescent patients according to abnormal infiltrate patterns on the chest X-ray were compared. Methods: From 2012 to 2015, patients (n=336) diagnosed with MP at Yeungnam University Medical Center have been classified as eiher lobar pneumonia or bronchopneumonia based on the infilterate patterns observed on chest X-ray. Cases were analyzed retrospectively for gender, age, seasonal incidence rate, main symptoms (fever duration, extrapulmonary symptoms), and laboratory results, including white blood cell count, hemoglobin, platelets, C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR), as well as concurrent respiratory virus infection. Results: The following results were observed. First, lobar pneumonia affected 22.0% of all MP patients and was the most common in preschool children, with a high incidence rate in November and December. Second, lobar pneumonia had a longer fever duration than bronchopneumonia (p<0.001), and also showed significantly higher platelets (336.8 vs. $299.1k/{\mu}L$, p=0.026), ESR (46.3 vs. 26.0 mm/hr, p<0.001) and CRP (4.86 vs. 2.18 mg/dL, p=0.001). Third, viral co-infection was more common in bronchopneumonia (p=0.017), affecting 66.7% of infants and toddlers (p=0.034). Finaly, lobar consolidation was most common in both lower lobes. Conclusion: MP in children has increased in younger age groups, and the rate of lobar pneumonia with severe clinical symptoms is higher in older children.

A 2-year-old castrated male, Cocker spaniel dog with a history of chronic productive cough for 2 to 3 months and with unsuccessful treatment was referred to Veterinary Medical Teaching Hospital, Seoul National University. On thoracic radiographs, there were alveolar infiltrations at left cranial and right caudal lung fields, and soft-tissue opacity round to oval images at overall lung field. The bronchi were dilated, tortuous and not tapered. Abnormal air was accumulated focally in the caudodorsal lung fields. To scrutinize the soft-tissue opacity image and accumulated air, computed tomography (CT) was done. On CT images, severe cylindrical or tubular bronchiectasis was confirmed. And the soft-tissue opacity images were found in the dilated bilated and thought to complexes of mucous plugs, inflammatory cells, necrotic and fibrotic tissue. The dog was dead next day to the CT scan, so necropsy and histopathologic examination were perfermed. On the histopathology, there were cylindrical bronhiectasis and severe diffuse chronic fibrinous necropurulent bronchitis and bronchopneumonia. In this case, it was difficult to diagnose the bronchiectasis only with radiography due to the concurrent lesions, such as pulmonary infiltrations and mucous plugs, which was identified by computed tomography. Thus, computed tomography is considered as a useful modality to confirm tile bronchiectasis camouflaged by the concurrent lesion.

Background: Respiratory troubles have economic impacts in countries where livestock industry is an important segment of the agricultural sector, as well as these problems may cause significant economic losses for bovine producers. Various practical methods are used to assess diseases that affect the bovine respiratory system. Ultrasonography is a noninvasive tool that has been used frequently in diagnosis of various animal diseases. The present study was designed to establish whether thoracic ultrasonography is a diagnostic tool for detection of respiratory troubles in weaned buffalo and cattle calves, as well as to assess its prognostic value in comparison with clinical respiratory scores. Thirty five (15 buffalo and 20 cattle) calves were included. Twelve (6 buffalo and 6 cattle) clinically healthy calves were enrolled as controls. Results: Based on physical examinations, clinical respiratory scores (CRS), ultrasound lung scores (ULS) and postmortem findings, animals were classified into 4 groups as pulmonary emphysema (n = 8), interstitial pulmonary syndrome (n = 7), bronchopneumonia (n = 12), and pleurisy (n = 8). The mean values of CRS and ULS were significantly higher in diseased calves (P < 0.01). In calves with pulmonary emphysema and interstitial syndrome, thoracic ultrasonography revealed numerous comet-tail artifacts, which varied in numbers and imaging features. Furthermore, variable degrees of pulmonary consolidation with alveolograms and bronchograms were noticed in bronchopneumonic calves. In addition, thick irregular or fragmented pleura with pleural effusions and fibrin shreds were imaged in calves with pleurisy. A weak correlation was calculated between CRS and ULS (r = 0.55, P < 0.01). Hematologically, the counts of white blood cells, activities of aspartate aminotransferase and partial tensions of carbon dioxide were significantly increased in all diseased groups. Serum concentrations of total globulins were higher in claves with bronchopneumonia (P < 0.05). The partial tension of oxygen was decreased in all diseased calves (P < 0.05). Conclusions: Thoracic ultrasonography is a diagnostic tool for various lung troubles and assessment the grade and severity of pulmonary diseases, as well as it can be used as a follow-up tool for evaluating the prognosis of respiratory troubles and monitoring the efficacy of therapies.
