  • Four 5 month old calves were died after showing respiratory distress after long-distance transportation at winter season. They were diagnosed as fibrinous lobar pneumonia caused by Mannheimia (M.) haemolytica. Grossly, lungs were attached onto the pleura by fibrin, with a rich yellowish fluid in thorax. The cut surface of the lung was showed marbled pattern of the reddish or greyish consolidation and widened interlobular septa by fibrin deposition. Histopathologically, parenchymal necrosis was delineated by a band of the degenerated inflammatory cells, and distended interlobular septa with serofibrinous exudates and vascular thrombosis with alveolar capillaries degeneration and abundant serofibrinous exudates in alveoli. M. hemolytica were isolated from all calves, and bovine viral diarrhea virus and parainfluenza type 3 virus in one calf were detected by RT-PCR. Thus, it was concluded that this case was diagnosed as pneumonic mannheimiosis suggested by complex infection with viruses after long-distance transportation and coldness.

  • Nine cases of puppies infected with acute canine distemper were investigated and the pathological findings are as follows. 1. Fibrinous-necrotic lobar pneumonia. 2. Focal hemorrhagic necrosis of liver, kidney and lymph follicles. 3. Hemorrhages in other tissues.

  • Mannheimia haemolytica is an opportunistic bacterium that is widely recognized among the bovine respiratory disease (BRD) complex in cattle. Five Hanwoo with a history of fever, anorexia and dyspnea were died within 2 days in a the middle of summer. Four cattle were pregnant. The cattle house were located in mountainous area but the window for air ventilation was open only one side. In addition, the fecal material for fermentation was located indoor. Air ceiling fan did not work. The indoor temperature was $40^{\circ}C$. After working on air fan, the indoor temperature was still $36^{\circ}C$. On necropsy, there was fibrinous pleuritis with a rich yellowish pleural fluids in the thorax. The cross-section of the lung showed lobar fibrinonecrotic pneumonia with expanded interlobular septa by edema and fibrin. Microscopically, parenchymal necrosis with dense layer of inflammatory cells were observed surrounding interlobular septum. Fibrin and inflammatory cells were filled in the alveoli. Bacteriological cultures of pulmonary tissue showed growth of M. haemolytica. This pneumonia case in Hanwoo suggests that environmental stressors such as high temperature, insufficient air ventilation, and pregnancy be the cause of mannheimoisis. Control of environmental stressor, such as temperature indoor is necessary to prevent BRD caused by M. haemolytica.

  • This is a report on four cases of the lobar emphysema due to proximal bronchial obstruction in the Department of Thoracic Surgery, Hanyang University Hospital, during the period of three and half years from 1972 to 1975. First case, a two years old male child was referred to our Department with the lobar emphysema of the lower lobe of the right lung with pneumonia. This emphysema was developed after aspiration of a piece of peanut. Bronchoscopy revealed that the bronchus of the right lower lobe was obstructed with the foreign body, however removal of the peanut through bronchoscope was not attempted because of corruption and softening of the peanut. The removal of the peanut by bronchotomy was performed after subsiding of acute phase of pulmonary infection. Postoperative course was uneventful and the emphysema was disappeared. Second case, a twenty months old female baby was referred to our Department with lobar emphysema of the lower lobe of the left lung. The emphysema was suddenly developed with coughing and dyspneic symptoms and the diagnosis was made roentgenologically. She gave a history of reccurrent infections of the respiratory tract after birth. Bronchoscopy showed an obstruction of the left main bronchus with the growing of fibrinous tissue on the bronchial mucosa. The protruded tissue in the left main bronchus taken out about O.8ml with biopsy forceps for histological examination. After this procedure, the emphysema of the left lung was disappeared. Histological finding was reported to be a chronic inflammatory granulation tissue. Third case, a two and half years old male child was referred to our Department with roentgenological lobar emphysema. Two weeks prior to admission he had an episode of sudden onset of coughing attack with dyspnea. Bronchoscopy revealed that the bronchus of the left lower lobe was obstructed with a mass which was strongly suspected of a neoplastic tissue. At operation, there was found a perforation of enlarged tuberculous lymph node in the bronchus of the left lower lobe and protrusion of granulation tissue into the bronchus. Ruptured orifice on themembranous wall of the left lower lobe bronchus was closed with interrupted suture after the" removal of a perforated tuberculous lymph node. Postoperative course was uneventful and antituberculous chemotherapy was given. Fourth case, a 47 years old man was admitted to our Department with the complaint of severe dyspnea of few months duration. Twenty years ago, he had a history of lung tuberculosis and was treated for many years. X-ray examination including tomography and bronchography revealed that the upper lobe of the right lung was destroyed with cavities, the lower lobe was completely shrunk, and the right middle lobe was strongly overdistended with narrowing bronchial trees. Differential bronchospirometry and lung scanning confirmed that the respiratory function of the affected lung was impaired almost totally. The value of the right lung was calculated on 6% of oxygen uptake, 1% of Minute volume, and 32% of vital capacity. The right pneumonectomy was performed under the careful consideration of anesthetic and surgical procedures. Postoperative course was uneventful and the respiratory function was improved nearly to the normal level.evel.

  • A four-year-old male elk (Cervus elaphus nelsoni) was diagnosed as pulmonary aspergillosis and renal oxalosis. Clinical signs were coughing, sneezing, respiratory distress, salivation, moderate anorexia, and progressive emaciation. Main gross lesions were fibrinopurulent tonsillitis, diffusely fibrinous pleuritis, and distinct lobar pneumonia with purple red in color. Most of the pulmonary lobes had numerous well demarcated 0.5 to 2 cm yellowish white discrete or confluent nodules that were surrounded by pale red zones. Histopathologically, the affected lungs were disseminated necrotizing pyogranulomas including fungal hypae, vasculitis, and diffusely fibronecrotic pleuritis. The renal lesions were composed of extensive tubular necrosis with large numbers of rosette-formation by birefringent oxalate crystals. Aspergillus fumigatus was isolated from lesions of the lungs. It seems to be a first report for pulmonary aspergillalis and renal oxalosis of a farmed elk in Korea.

  • An epizootic of calf diarrhea occurred in an extensive dairy farm located in Gangwondo province in December of 1985. The patients showing fever, chills, complete anorexia and watery diarrhea sometimes dysentery were concentrated among the calves ranged from 8 days to 3 months old and many of them died in acute course. The five carcases were examined by pathological and bacteriological means. The predominant gross lesions were edematous swelling of the mesenteric lymph nodes, profuse catarrhal or diphtheritic enteritis and extensive purulent bronchopnenomonia or lobar fibrinous pneumonia. Microscopically the lesions of the liver and spleen were characterized by coagulative necrotic foci and granulomatous nodules. The spleen and lymph node showed also proliferative changes of reticular cells and involution of intestinal lymphatic nodules were noticed. The strains of Salmonella(S) species isolated from the liver, spleen, bile juice, peritoneal fluid and thoracic fluid were identified serologically as S. dublin. These clinical and pathological findings of the disease were those of acute enteritis form of salmonellosis and characterized by high morbidity and mortality among the calf herd. The report also signifies the first description of an epizootic of bovine salmonellosis caused by S. dublin in Korea.
