Six entomopathogenic fungus isolates, Beauveria bassiana J57A, Nomuraea rileyi J125A, Paecilomyces farinosus J3A, Paecilomyces fumosoroseus J50A, Metarhizium anisopliae J88, Aspergilius sp. J64A, causing muscardine disease and aspergillosis in the silkworm, Bombyx mori were investigated for their cultural and morphological characteristics (on PDA culture media within 14 days at $24^{\circ}C$). The results showed that they differ each other from the features of cultural characteristics (colony elevation, colony color, colony growth rate) or morphological characteristics (conidiogenous cell structure, phialides, conidia size and shape). Among cultural characteristics, colony color is the easiest recognizable character between isolates. The morphological characteristics of each fungal isolate correspond to the descriptions of current system of classification.

A three years old male Jackass penguin(Spheniscus demersus) showed anorexia, depression, respiratory problem for a few days, followed by clinical treatment for 20 days resulted in death. Grossly, multiple white nodules measuring 2~3 mm in diameter were observed in the surface of and inside lung, liver, kidney, thoracic wall. Microscopically, granuloma formations were observed in the lung and liver. The margin of granuloma surrounded by connective tissue barrier and infiltrated lymphocytes, and also observed giant cell near the granuloma. By Periodic acid Schiff reaction, hyphae were detected in granuloma of lung and liver. This case was a chronic and systemic aspergillosis caused by Aspergillus fumigatus infection in a Jackass penguin at a zoo.

폐 국균종은 폐결핵 등 만성 폐질환으로 인하여 파괴된 폐조직에 국균이 2차적으로 기생하여 발생하는데, 치명적 각혈 등의 증상이 발생할 수 있기 때문에 상당수 증례에서 수술적 치료를 필요로 한다. 이에 최근 10년 간의 수술적 경험을 고찰하고자 한다. 대상 및 방법: 1992년 8월부터 2002년 7월까지 폐절제술 후 병리학적으로 폐 국균종으로 확진된 31명의 환자를 대상으로 호발연령 및 성비율, 주소, 술전검사, 술식의 종류, 지저질환, 술 후 합병증 등을 분석 검토하였다. 결과: 호발연령은 30대와 40대(64.5%)이었으며, 술 전 주요증상은 객혈이었다(27명, 87.1%). 31명 모두에서 술 전 항결핵제 투여경력이 있었으며 19명(61.3%)에서 단순 흉부 방사선 사진상 연부조직 음영이 있는 큰 공동이 관찰되었고 흉부 전산화 단층촬영에서는 31명 모두에서 관찰되었다. 국균객담검사상 37.9%, 혈청 면역 확산 검사상 83.3%의 양성률을 보였다. 폐상엽이 19예(61.3%)로 호발부위였으며 대부분에서 폐엽절제술을 시행하였다. 술 후 병리조직검사상 전 예에서 결핵과 동반되어 있었다. 주요 합병증으로는 농흉 3예(9.7%), 지속적인 공기 누출 2예(6.45%), 사강 2예(6.45%), 술 후 출혈 1예(3.23%) 등이었다. 술 후 사망은 1예(3.23%)로 양측성 폐 국균종에서 수술한 반대쪽의 대량출혈로 사망하였다. 결론: 성비, 나이, 임상증상, 폐결핵과의 연관성, 병변부위 및 수술방법, 합병증 등에 대해서 과거 1963년부터 1992년까지 수술받은 80예와 비교하여 볼 때 큰 차이는 없었다. 진단 기법상 혈청검사는 술 전 아주 높은 양성률을 나타내었고 흉부전산화단층촬영의 높은 진단율은 폐 국균종의 진단과 수술에 매우 중요하다고 사료된다. 복합형 폐 국균종의 경우 흉막유착과 폐문의 경화, 잔존폐의 불완전한 확장 때문에 수술에 어려움이 있어 많은 시간 약물요법과 기관지 동맥 색전술 등의 내과적 치료를 선호하게 되는 데 이와 더불어 공동절개술 등의 비교적 비침습적인 수술방법도 추천되며 최근 합병증의 감소와 더불어 단순형 폐 국균종은 조기에 수술을 적극적으로 고려함이 요구된다.

Aspergillus fumigatus is associated with invasive disease aspergillosis in immunocompromised individuals. The major aim of this study was to investigate the biochemical and immunological responses of male Wistar rats against A. fumigatus experimentally-induced pulmonary fungal infection. Nostril experimental exposure of male Wistar rats to a high dose of A. fumigatus freeze-dried preparation for only 24 hr resulted in a significant increase in levels of catalase, nitric oxide and lipid peroxide in lung homogenates, compared to those of the control animals. However, the oxidative status of the lungs of rats challenged with killed fungus did not change significantly, except for the stimulation in the level of lipid peroxide. IgG level was significantly elevated only in rats that received two low doses of fungus, compared to unexposed animals (p < 0.005). Examining the lung of rats exposed to A. fumigatus revealed no abnormal changes, except for pus in bronchial lumen spaces and per bronchial inflammation. Histologically, large numbers of granuloma cells were evident in the lungs of challenged rats, while no granuloma formation was evident in the lungs of rats exposed to killed fungus.

Members of the genus Aspergillus are the most common fungi and all reproduce asexually by forming long chains of conidiospores (or conidia). The impact of various Aspergillus species on humans ranges from beneficial to harmful. For example, several species including Aspergillus oryzae and Aspergillus niger are used in industry for enzyme production and food processing. In contrast, Aspergillus flavus produce the most potent naturally present carcinogen aflatoxins, which contaminate various plant- and animal-based foods. Importantly, the opportunistic human pathogen Aspergillus fumigatus has become the most prevalent airborne fungal pathogen in developed countries, causing invasive aspergillosis in immunocompromised patients with a high mortality rate. A. fumigatus produces a massive number of small hydrophobic conidia as the primarymeans of dispersal, survival, genome-protection, and infecting hosts. Large-scale genome-wide expression studies can now be conducted due to completion of A. fumigatus genome sequencing. However, genomics becomes more powerful and informative when combined with genetics. We have been investigating the mechanisms underlying the regulation of asexual development (conidiation) and gliotoxin biosynthesis in A. fumigatus, primarily focusing on a characterization of key developmental regulators identified in the model fungus Aspergillus nidulans. In this review, I will summarize our current understanding of how conidiation in two aspergilli is regulated.

When a person was suffered from vocal cord paralysis or glottic insufficiency, injection materials (e.g Teflon, Bovine collagen, Autologous fat & tendon, Gelfoam) into the vocal cord have been widely used. But each injection material has some disadvantage. We introduce the Restylane which is composed of a hyaluronic acid, artificially producted. It has advantage of rate foreign body reaction, proper endurance, easy to injection. The patient was 55-year-old woman who showed left vacal cord paralysis after pneumonectomy due to aspergillosis, taken the type I thyroplasty and arytenoid adduction. The middle portion of left vocal cord has some atropic mucosal change, slight chink was noted. The restylane injection into vocal cord was done with suspension laryngoscopy under general anesthesia. In the 3 month follow-up after Restylane injection, the quality of voice has been better progressively. We report a case of Restylane injection as a new method for the improvement of quality of voice.

Eleven cases of pulmonary resection had been performed for pulmonary aspergilloma in the department of thoracic and cardiovascular surgery, School of Medicine, Kyungpook National University from August 1984 to July 1988. The patients were consisted of six males and five females and were evenly distributed from third decade to sixth decade. Hemoptysis was usually presenting symptom [72.2%] and the variable was the interval between symptom onset to surgical resection, which was ranged from few months to several years In the plane chest films, intracavitary fungus balls were noted in five cases [5/11] and upper lobe involvements were seven cases [7/11]. Aspergillus fumigatus was identified preoperatively in three cases among the eight cases of sputum culture. Mean preoperative FVC and FEV 1.0 values were in normal range. Eleven pulmonary resections were done by eight lobectomies, two segmentectomies and one pneumonectomy. The lesion was superimposed upon old tuberculosis in eight patients, in one upon bronchiectasis and in two upon tuberculous bronchiectasis. Five complications appeared postoperatively which included ARDS [1 case] bleeding [2 cases], persistent air leak[1 case], and dead space [1 case].

Backround: Pulmonary aspergilloma is a potential life-threatening disease resulting from massive hemoptysis. Pulmonary aspergilloma has been treated surgically for many years, however, it has also had higher risk of mortality and complication rate. The purpose of this study is to analyze the operative methods and the types of complications. Material and Method: Sixty patients who underwent surgical resection for pulmonary their medical reconrds. Result: The mean age was 46.3$\pm$13.4 years(range 20 to 76 years). The most common clinical presentation was hemoptysis which occurred in 48 patients(80%). Pulmonary tuberculosis was the most common pre-existing disease, occurri9ng in 28 patients(46.7%). The other associated lung diseases were bronchiectasis(n=11), silicosis(n=2), and chronic pnumonia(n=1). Operative proceudres wer lobectomy in 35 patients, pneumonectomy in 6, segmentectomy in 5, lobectomy and thoracoplasty in 3, segmentectomy and thoracopasty in 1, and cavernostomy in 10. The operative mortality was 6%(n=3) in lung resection patients but 0% in cavernostomy patients. The most common complications were prolonged air leakage, wound infection and postoperative bleeding. Conclusion: In most cases of pulmonary aspergilloma surgical resectin remains the only effective therapy. However, cavernostomy may be more effective for pulmonary aspergilloma patients with decreased pulmonary functions and for patients with high risk for lung resection.
