Desmoplastic ameloblastoma is a rare histologic variant of ameloblastoma. It shows important differences in anatomic distribution, histologic appearance, and radiographic findings compared with the general type of ameloblastoma. It is histologically characterized by an abundance of densely collagenous stroma and radiographically a mixed radiolucent-radiopaque lesion. We present three cases of desmoplastic ameloblastoma. All the patients complained on buccal swelling with or without pain and the sites of occurrence were the anterior and the premolar region. Plain radiographs showed mixed radiopaque-radiolucent lesion with ill-defined or diffuse sclerotic margin and no external root resorption. Additionally, CT scans revealed buccal expansion and relatively well-defined margin of the lesions. The clinical and radiographic features of the presented cases were compared with those of the desmoplastic ameloblastoma in the previous literatures.

강창훈,허혜순,박정규 경상대학교 농업생명과학연구원 2003 농업생명과학연구 Vol.37 No.3

경남 진주, 사천, 김해 지역의 단감 과수원에서 단감꽃을 방문하는 방화곤충의 종류와 일주활동 리듬을 조사하였다. 단감꽃을 방화하는 곤충은 모두 2목 15종이었으며, 그 중에서 양봉꿀벌이 전체의 73.6%로 우점종이었고, 일본애수염줄벌이 10.2%, Andrena habes와 좀뒤영벌이 각각 3.0%를 차지하였다. 우점종인 양봉꿀벌은 13:00부터 15:00까지 가장 활발하게 활동하였다. Insect visitors were surveyed on sweet persimmon blossoms at Jinju, Sacheon, and Gimhae in Gyeongnam province, 2001. Fifteen species in 2 orders were collected. Honeybee, Apis mellifera, was a dominant species representing 73.6% and followed by Tetralonia nipponensis(10.2%), Andrena habes and Bombus ardens ardens(3.0%) in turn. Foraging of honeybee was most active between 13:00 to 15:00.

강창훈,이상명,허혜순,박정규 경상대학교 농업생명과학연구원 2002 농업생명과학연구 Vol.36 No.4

우리나라 단감의 수출선을 다변화하기 위해서는 검역문제를 해결하여야 한다. 본 연구는 이러한 문제를 해결하기 위하여 단감 수확과에 잔존하는 해충의 제거방법으로 고온처리와 air shower 처리의 효과를 실험하였다. 점박이응애를 단감(부유)에 접종하고 50℃에서 4시간 처리하면 99.4%의 치사효과를 얻을 수 있었지만, 45℃에서 3시간이나 50℃에서 1시간 이상 처리하였을 때 감이 연화되는 현상이 나타났다. 단감의 수확과에 존재하는 충은 톡토기류, 균식성응애, 잎응애의 3종류이었는데 균식성응애의 밀도가 가장 높았다. 꽃받침 윗면에 존재하는 충은 100% 제거할 수 있었다. 그러나 아랫면에 존재하는 충은 톡토기와 잎응애는 air shower로 100과 중에서 2마리 수준까지 제거할 수 있었지만 균식성응애는 원래 밀도가 높아서 모두 제거하는 데는 무리가 있었다. 따라서 수확과에 잔존하는 해충을 완전히 제거할 수 있는 새로운 기술의 개발이 요구된다. No quarantine pests are allowed in exporting fruits. To meet the quarantine requirement, it is essential to remove pests from harvested fruits. We tested a few methods to remove or kill the pests on persimmon fruits. The efficacies of hot-air treatment and air shower were tested on sweet persimmon. Hot air (50℃) treatment for 4 h showed 99.4% mortality of Tetranychus urtioae. However, longer than 3-h treatment at 45℃ and 1-h treatment at 50℃ caused softening of the fruits. The efficacy of air shower generated with a compressor (max W.P., 200 lbs; 10-14 sec shower/fruit) in removing the pests on persimmon fruits was tested. Collembolans, fungus-feeding mites, and leaf mites on and under the calyx lobes were the common pests on persimmon fruits. All the pests on the calyx could be removed by the air shower treatment. However the pests under the calyx were resistant to the air shower treatment. Collembolans and leaf mites could be reduced to two individuals per 100 fruits (98% removal). However, the fungus-feeding mites could not be removed by the air shower because of the high initial density of the mite and the shield by the calyx. Therefore it is evident that the air shower treatment cannot remove 100% of the pests under the calyx. Therefore development of new technology is required to remove pests from harvested persimmon fruits.

Ovarian development and oviposition response of two vectors of pine wood nematode, M. alternatus and M. saltuarius

Hyang-Mi Cheon,Hye-Soon Huh,Hee-Sun Rho,Kwang-Sik Choi 한국응용곤충학회 2011 한국응용곤충학회 학술대회논문집 Vol.2011 No.05

The ovarian development and oviposition response of two vector beetles of pine wood nematode, Monochamus alternatus and M. saltuarius, was investigated. The ovary structure of two beetles was investigated by means of light microscopy. The ovary of both beetles was composed of two ovaries that are connected by a common oviduct. Each of the two ovaries was consisted of twelve ovarioles, the functional units of female oogenesis. The ovary type was meroistic telotrophic with nurse cells and oocytes in the tropharium. Ovarian development of two vector beetles was completed at 12-14 days after maturation-feeding pine twigs. Aspect of accumulation of vitellogenins in the ovary of two vectors showed difference in developmental stages and major yolk proteins, differently from vitellogenin. To investigate oviposition performance of two vector beetles, we provided P. thunbergii and P. koraiensis bolts for egg laying and collected emerged adults from each pine bolts in the next year. M. saltuarius females made more oviposition wounds and entrance hole of larvae than M. alternatus on pine bolts. We also investigated whether two beetles can transmission of Bursaphelenchus xylophilus and the European type of B. mucronatus via oviposition to noninfected dead pines. 48-83% from newly emerged adults of two beetles were carried two species nematode. This results suggested that two species beetles can transmit nematodes through oviposition performance and transmitted nematodes successfully propagate in non-infected dead pines.

First report of M. saltuarius vectored the European type of B. mucronatus on P. densiflora and P. koraiensis in Korea

A survey was conducted in the northern conifer forests of Korea from February to May in 2009 for the Monochamus species vectored Bursaphelenchus species. Dead pine trees infested with bark beetle larvaes were collected from Pinus densiflora and P. koraiensis located in the following target areas: Pocheon, Yeongi, Jincheon, Chuncheon, and Bonghwa. A cerambycid beetle, M. saltuarius was only found from sampled log piles in target areas. Bursaphelenchus species carried by M. saltuarius was only isolated in Pocheon, Gyeonggi province. The nematodes recovered from 17 (71%) of 24 beetles from P. koraiensis and 12 (75%) of 16 beetles from P. densiflora. The average number of nematode per adult was 1,974 and 11,823 from P. koraiensis and P. densiflora, respectively. The nematode was also recovered from the inner bark of both Pinus species infested with M. saltuarius larvae. Bursaphelenchus species identification was performed by morphological characters and molecular analysis with ITS-RFLP patterns and sequences of ITS and D2D3 region. Both morphological and molecular characters match well with the original description of the European type of B. mucronatus. This is the first report of M. saltuarius species as a vector of the European type of B. mucronatus on both P. densiflora and P. koraiensis in Korea.

Survey of the members of Bursaphelenchus xylophilus group nematodes and Monochamus species in conifer forests in Korea

Hyang-Mi Cheon,Yil-Sung Moon,Hye-Soon Huh,Jung-Jin Park 한국응용곤충학회 2009 한국응용곤충학회 학술대회논문집 Vol.2009 No.10

Since pine wilt disease was first reported in Busan in 1988, this disease has become a serious threat to pine forests in Korea. A general survey for Bursaphelenchus xylophilus group (B. xylophilus, B. mucronatus) nematodes were carried out to determine their geographic range, host tree species and insect vectors, Monochamus species. Based on the survey results, B. xylophilus were found over 57 cities or district and a similar nematode, B. mucronatus also has been isolated over 30 cities or district including Jeju and Pocheon. The Asian type of B. mucronatus was founded from Pinus thunbergii and P. densiflora, generally associated with M. alternatus as its insect vector. The European type of B. mucronatus which was limited distribution to the central areas, such as Yeongwol, Bonghwa, Yeongdeok, was also found on P. koraiensis and P. desiflora associated with M. saltuarius. Both Monochamus species transmitted both Bursaphelenchus species and co-existed in Muju and Yeongdeok predicted as their range margin. Their range margins shifted northwards compared to 2006, seemingly as a result of climate change. Recently, the European type of B. mucronatus has been identified in other several areas since it was first reported in Pocheon in 2008. Several reports indicate the potential pathogenicity of European type of B. mucronatus and other species, B. sexdentati and B. lenoni in Europe. Therefore, sustainable survey and the study for the newly invading Bursaphelenchus species as well as the member of B. xylophilus group should be performed to protect Korean forests.

한국인 Graves씨병에 있어서의 HLA항원 분포에 관한 연구

허갑범,이혜리,이상용,박기일,김춘규,김윤정,송경순,이삼열 인제대학교 1982 仁濟醫學 Vol.3 No.1

Graves씨병은 자가면역성 갑상선 질환의 하나로 유전적인 요소가 중요한 역활을 한다. Graves씨병에 대한 감수성과 HLA항원 분포와의 연관성을 극명하기 위해 한국인 Graves씨병 52예를 대상으로 HLA항원 분포를 검사하고 정상대조군 72예와 비교 분석하여, 외국과는 달리 Graves씨병 환자에서 HLA-All 증가되는 반면 HLA-B locus 항원에서는 유의한 차이가 없음을 관찰하였다. Graves' disease is one of the autommune thyroid diseases and genetic factors seem to play an important role in the pathogenesis of Craves' disease. Lymphocytes of 52 Korean patients with Graves' disease and 72 normal unrelated controls were examined for HLA antigens by the microcytotoxicity test. Also antithyroglobulin and antimicrosomal autoantibody tests were performed on 43 patients with Graves' disease The following results were obtained: 1.The frequency of the HLA-A11 antigen in patients with Graves' desease was increased to 30.8% compared to 12.5% incontrols (p<0.025). 2.There's no consistent association between Graves' disease and HLA-B locus antigens including B8 and Bw35 which were significantly increased in Caucasians and Japaneses, respectively. 3.No significant differences of HLA antigens were present at the HLA-C locus. 4.No significant correlation was observed between the frequency of thyroid autoantibodies and HLA antigens in Korean patients with Graves' discase. In summary, these results showed close association between Graves' disease and HLA-A locus antigen(A11) but no significant correlation with HLA-B locus antigens in Korean patients with Graves' disease. These findings might suggest racial difference.
