We performed post-operative hemodynamic evaluation and lung perfusion scan after left lung transplantation in dog. The heart & lungs were extracted from donor dog while the both lungs were flushed with 4oC Euro-Collin`s solution after heparinization & infusion of prostaglandin E1.In the recipient dog, anastomosis of the left atrial cuff was performed by continuous 4-0 Prolene everted suture, and bronchial anastomosis by telescope method with 4-0 Prolene continuous suture. The end-to-end anastomosis of left main pulmonary arteries was performed with continuous 6-0 Prolene suture. After closure of left thoracotomy incision, the lung perfusion scan was performed post operative 2 days for evaluation of the function of the transplanted lung which showed good perfusion. The dog was sacrificed in the post-operative 5 days for autopsy.

Suppuratives bronchopneumonia was found in a 3-month old domestic muskrat (Ondatra zibethicus). Dead muskrat showed hemorrhagic nasal discharge, severe hemorrhage and consolidation were observed in the lungs in necropsy. Histologically, severe polymorphic neutrophils and alveolar macrophages were infiltrated in the bronchus, bronchioles, alveoli. P. multocida and B. bronchiseptica were identified from the lungs, Klebsiella was isolated from the cecum. We demonstrated those organisms by biochemical test and confirmed P. multocida capsular type A by means of polymerase chain reaction (PCR).

Pathological studies, on the lung of 27 cases of bovine parasitic bronchitis which were secured from abattoirs in Korea, were performed and discussed. The chief pathological findings were as follows. Grossly, the lungs were shown various degree of lobular consolidation, collapse and alveolar emphysema around the bronchi in which nematodes of Dictyocaulus viviparus were present. Emphysema and edema were observed in the interlobular septa. The lesions were encountered mostly in the caudal and ventral borders of the diaphragmatic lobes. In all the cased of parasitic bronchitis in which thickening of the visceral pleura and fibrinous deposition on the pleural surfaces were not seemed to be entirely due to the lungworm infection. Microscopically, bronchopneumonia, peribronchial and peribronchiolar lymphoid hyperplasia, lympho-reticular broncho-occlusive legion, and bleakthrough lesion were examined in the affected lungs.

A survey on pneumonic lungs and its histopathological changes of the slaughtered pigs from the southern area of Chungbuk province was carried out during the period from January to December 1999. Pneumonic lungs were attempted bactenological findings and antibiotic susceptibilities. The results obtained were as follows; 1. Of 158 slaughtered pigs, 97(61.4%) pigs had pneumonic lesions in the lung, and the prevalence was high in winter, spring, autumn, and summer in order. f. The bacteria isolated from pneumonic lesions were pasteurella spp, 13 heads(34.2%), streptococcus spp, 6(IS.8%), actinobacillus spp, 3(7.9%), coliform 4(10.5%) and the other bacteria, 12(31.6%). 3. These isolates were highly susceptible to the antibiotics of enrofloxacin 30(78.9%), cephalothin 23(73.6%) and ceftiofur 27(71 %). 4. Histopathologically, swine enzootic pneumonia and pleuropneumonia lesions were observed. The swine enzootic pneumonia lesions were consisted of peribronchiolar lymphoid hyperplasia and exudate in alveolar lumen. The pleuropneumonia lesions were consisted of thrombosis, alveolar wall thickened by mononuclear cells and neutrophil deposition.

Connective tissue diseases (CTDs) can affect all compartments of the lungs, including airways, alveoli, interstitium, vessels, and pleura. CTD-associated lung diseases (CTD-LDs) may present as diffuse lung disease or as focal lesions, and there is significant heterogeneity between the individual CTDs in their clinical and pathological manifestations. CTD-LDs may presage the clinical diagnosis a primary CTD, or it may develop in the context of an established CTD diagnosis. CTD-LDs reveal acute, chronic or mixed pattern of lung and pleural manifestations. Histopathological findings of diverse morphological changes can be present in CTD-LDs airway lesions (chronic bronchitis/bronchiolitis, follicular bronchiolitis, etc.), interstitial lung diseases (nonspecific interstitial pneumonia/fibrosis, usual interstitial pneumonia, lymphocytic interstitial pneumonia, diffuse alveolar damage, and organizing pneumonia), pleural changes (acute fibrinous or chronic fibrous pleuritis), and vascular changes (vasculitis, capillaritis, pulmonary hemorrhage, etc.). CTD patients can be exposed to various infectious diseases when taking immunosuppressive drugs. Histopathological patterns of CTD-LDs are generally nonspecific, and other diseases that can cause similar lesions in the lungs must be considered before the diagnosis of CTD-LDs. A multidisciplinary team involving pathologists, clinicians, and radiologists can adequately make a proper diagnosis of CTD-LDs.

Lung-resident memory T cells (T_RM) play an essential role in protecting against pulmonary virus infection. Parenteral administration of DNA vaccine is generally not sufficient to induce lung CD8 T_RM cells. This study investigates whether intramuscularly administered DNA vaccine expressing the nucleoprotein (NP) induces lung T_RM cells and protects against the influenza B virus. The results show that DNA vaccination poorly generates lung T_RM cells and massive secondary effector CD8 T cells entering the lungs after challenge infection do not offer sufficient protection. Nonetheless, intranasal administration of non-replicating adenovirus vector expressing no Ag following priming DNA vaccination deploys NP-specific CD8 T_RM cells in the lungs, which subsequently offers complete protection. This novel 'prime and deploy' strategy could be a promising regimen for a universal influenza vaccine targeting the conserved NP Ag.

The purpose of this study is to provide the basic data for reducing unnecessary radiation dose to the abdomen and fetus of pregnant women by presenting proper height of shielding protector for efficient abdominal shielding in chest PA examination of Korean pregnant women. The subjects of this study were 288 persons who were eligible for this study among 798 pregnant women who had chest PA examination from January 1, 2015 to December 31, 2016 Retrospective study was performed. Measurements was performed from the apex of the right and left lungs to costophrenic angle of the right and left lungs and to the lowest costophrenic angle among the right and left lungs at the top of the image(this line called Joo's line in this study). The mean of the right and left lung height of pregnant women were 259.09 mm and 263.57 mm, respectively. Also, the average height of the Joo's line designed by the researcher for proper abdominal radiation protection was 322.15 mm. For proper and efficient abdominal radiation protection for pregnant women, it is necessary to adjust the shielding according to the height of the pregnant woman. It is appropriate that the height of the shielding protector should be adjusted so that the upper part of the shield is located at 342.30 mm below from upper part of the detector.

In magnetic resonance electrical impedance tomography (MREIT), a current-injection MR imaging method is adopted to produce a cross-sectional image of an electrical conductivity distribution in addition to MR images. The purpose of this study was to test the feasibility of MREIT for differentiating the canine lung parenchyma without and with pneumonia. Three normal healthy beagles and two mixed breed dogs with pneumonia were used. After attaching electrodes around the chest, we placed the dog inside our MR scanner. We injected as much as 30 mA current in a form of short pulses into the chest region. Reconstructed conductivity images of normal canine lungs exhibit a peculiar pattern of a relatively coarse salt and pepper noise. On the contrary, conductivity images of pneumonic canine lungs show significantly enhanced contrast of the lesions while the corresponding MR images show a little bit of contrast in the middle and caudal lung parenchyma due to the accumulation of pleural fluid. This preliminary study indicates that MREIT imaging of the chest may deliver unique new diagnostic information.
