A 7-year-old, spayed female Chihuahua with dyspnea, intermittent cyanosis, and dermal plaques was diagnosed with hyperadrenocorticism. Thoracic radiographs showed markedly hyperdense alveoli in multiple lung lobes. Computed tomography (CT) images showed lung mineralization confined to the lung parenchyma and pituitary macroadenoma. Pulmonary mineralization secondary to hyperadrenocorticism is commonly found on histopathologic examination. However, those lesions are rarely identified radiographically. We describe obvious pulmonary mineralization secondary to hyperadrenocorticism found on radiographs and present the first report regarding CT imaging of the mineralization. Pulmonary mineralization should be considered when a dog affected by hyperadrenocorticism shows diffuse lung mineralization on radiographs.

An unusual placentoid bullous lesion of the lung was reported. The patient was a 27-year- old woman with a 1-week history of chest pain and mild dyspnea. Chest radiographic studies showed multiple huge bullae in right upper lobe and variable-sized bullae in middle and lower lobes with collapse. She underwent right pneumonectomy with preoperative impression of bullous lung disease and emphysema. Histopathologically, the most distinctive features were villous structures within bullous airspace, which resembled placetal villi with degeneration.

Atelectasis may be defined as collapse of the lung due to absence of air within the alveoli. It may involve anatomic segments, lobes, or whole lungs but also may be a diffuse miliary process, as in the adult respiratory distress syndrome. The key to treatment are the anticipation and prevention of atelectasis in various clinical situations, the recognition and treatment of underlying disease, and the prompt initiation of vigorous treatment once atelectasis is found. Repeated assessment by physical examination is necessary to determine the presence of atelectasis and its response to treatment. During the period of January, 1981 to October, 1990, 100 patients with atelectasis were treated in the department of Thoracic and Cardiovascular Surgery, Pusan National University Hospital. There were 70 males and 30 females ranging from 3 days to 79 years of age. The occurrence ratio of right to left side was 2.1 : 1. The underlying pathologic lesions of atelectasis were pneumonia with effusion(28), lung ca.(24), pulmonary tuberculosis(24), and chronic empyema(9), The treatment procedure for atelectasis were closed thoracostomy in 26 cases, ressection in 21 cases, therapeutic bronchoscopy in 14 cases and etc.

Spontaneous pneumothorax is a common surgical problem and occurs most frequently in male patients under 40 years of age. The records of 336 cases in 269 patients, diagnosed and treated as spontaneous pneumothorax during the period of 1981, Jan.- 1987, Dec., at the department of thoracic and cardiovascular surgery, college of medicine, Hallym university, were reviewed retrospectively. The results were as follows; 1. Spontaneous pneumothorax was commonly found between the age of 20-40[55%]. 2. Sexual ratio of male to female was 4.4:1. 3. The most common symptoms were dyspnea and chest discomfort or chest pain. 4. Pulmonary tuberculosis was the most common cause of the disease[30.8%]. 5. Recurrent rate after closed thoracotomy drainage was 28.2%, and not recurred after operation. 6. Bullae or blebs were found most commonly at the apical segment of both upper lobes.

The change of catechol-O-methyltransferase (COMT) activity during regeneration of rat liver was studied. Cytosolic, mitochondrial and microsomal COMTs activities were estimated in regenerating rat livers over a period of ten days after $70\%$ (median and left lateral lobes) partial hepatectomy. The values of Km and Vmax in the hepatic enzymes were also measured. The activities of cytosolic and microsomal COMTs in regenerating rat liver after partial hepatectomy were found to be significantly increased between the second and the third day. Whereas the mitochondrial COMT activity did not change. The Vmax values of the cytosolic and microsomal COMTs in the regenerating rat liver were significantly increased at the second day after partial hepatectomy, however, the Km values of the above hepatic enzymes did not vary in all the experimental groups. Therefore, the results suggest that the biosynthesis of COMT was increased during the regeneration of rat liver.

Congenital bronchoesophageal fistula associated esophageal atresia usually presents in the newborn period or infancy but those without esophageal atresia are more insidious in disease process. Symptoms which include cough, hemoptysis, choking on swallowing liquids, uncommonly dysphagia, and epigastric discomfort may not begin until adult life. Most of the cases are curative unless there are serious underlying conditions. The diagnosis is usually made by gastroesophagoscopy, esophagogram, bronchogram and bronchoscopy. And the most of the cases can be cured by fistulectomy and resection of involved pulmonary lobes. We experienced one case of congenital bronchoesophageal fistula which occurred in a 13- year-old girl who complained of paroxysmal cough and intermittent hematemesis for 3 years.

To assess the correct role of operation in the management of bronchiectasis, two hundred and fifteen patients with bronchiectasis seen at the Thoracic & Cardiovascular Surgery Dept. of Catholic Medical College in Korea between 1972 & 1981 were reviewed and studied the combined disease [Pulmonary tuberculosis, paranasal sinusitis and general nutrition]. The result were as follows: 1.The incidence ratio of male to female was 1.8:1 & the age of second decade occupied 4596 of the total. 2.Bronchiectasis may occur in any lobe, however the vast majority of the cases are occur in dependent portion of the lung - basilar segment of the lower lobes, middle lobe, and lingular segment. Isolated upper lobe bronchiectasis is commonly associated with tuberculosis. 3.The bronchiectasis combined with the paranasal sinusitis was 25 patients [11.6%] in our cases and these occurred usually in both lower lung fields. 4.The average body weight of bronchiectasis patients were about 10 kilogram less than compairing to predicted normal body weight of Korean healthy person.

Chironomid adults attracted to the light were collected at Dangsan-ri, Muju-eup, Muju-gun, Jeollabuk-do in 2008-2009. Two new species, Lymnophyes parakitanaides sp. nov. and Parakiefferiella mujuensis sp. nov., and four unrecorded species, Cardiolcladius capusinus, Thienemanniella vittata, Conchapelopia pallidula, and Nilotanypus dubius were found and are described with illustrations. The genera Thienemanniella and Nilotanypus have not been previously reported in Korea. The genus Thienemanniella which belongs to Orthocladiinae is characterized by the radial sector retracted and apically fused with the costa, and the genus Nilotanypus which belongs to Tanypodinae is characterized by the absence of $R_{2+3}$, pubescent eyes and lack of the gonocoxal lobes.

Two new species of Martensia (Delesseriaceae, Rhodophyta) are described from Jeju Island, Korea. Martensia palmata sp. nov. is characterized by the following traits: more or less linearly elongated lobes arising from the distal margin of the flabellate membranous section; intact latticework with coarse and loose mesh; numerous spine-like projections on the leading margin of the latticework; tetrasporangia produced in sori along the entire blade; spermatangia borne in sori on the membranous section and the longitudinal lamellae of the latticework; and cystocarps borne on the margins of the membranous section. Martensia projecta sp. nov. has the following characteristics: subdichotomously furcated blades, with terminal segments slightly attenuated toward the apex; blades with uneven surfaces; basal parts with a multi-layered parenchymatous construction; small and poorlydefined latticework; tetrasporangia and spermatangia produced in sori on the membranous section; and cystocarps borne on the marginal surfaces of the blades. The existence of M. projecta sp. nov. supports the proposal that the genus Opephyllum Schmitz in Schmitz et Hauptfleisch should be assigned to the genus Martensia.

This study elvaluated clinically the surgical results of the thirty-eight patients who had exploratory thoracotomy for spontaneous pneumothorax between Jan. 1989 and Nov. 1992. Thirty three, or 86.8%, of the patients were male. The most frequent age of the spontaneous pneumothorax requiring thoracotomy was between fifteen years and twenty years. Sudden onset dyspnea and chest pain, which developed in thirty-five patients[89.5%], were the major chief complaints. Bleb and Bulla located in the both upper lobes were the most frequent causes of spontaneous pneumothorax for exploratory thoracotomy. There was no operative death. Postoperative morbidity included three cases of residual air space in the apical pleural space, tow cases of atrial fibrillation, and one each case of reoperation for bleeding, mediasitinitis, and sternal osteomyelitis. All postoperative complications were treated without any serious problems. This study suggests that early exploratory thoracotmy is desirable for patients with prolonged air-leak, massive air-leak, or multiple blebs and giant bullae on the computed tomography of the chest.
