대장 내시경 후에 발생한 급성 담낭염은 매우 드문 증례로 알려져 있다. 그러나 담낭염의 위험인자를 가진 환자에서 대장 내시경 후에 복통이 발생했을 경우, 반드시 담낭염을 감별진단해야 한다. 아직까지 정확한 발생 원인에 대해 밝혀진 바는 없으나 대장 내시경 전처치 과정에서 발생한 탈수, 대장 내시경에 의한 대장 점막 손상 등이 보고되었다. 저자들은 대장 내시경후 복통의 원인중 드문 질환인 급성 담낭염을 경험하였기에 문헌고찰과 함께 이를 보고하는 바이다.

췌장의 낭종성 질환은 현재 영상기술의 발달로 인하여 우연히 발견되는 경우가 많다. 그리고 췌장 낭종성 질환은 다양한 질환으로 이루어져 있으며 그 종류에 따라 다양한 악성 도를 보인다 췌관의 편평세포낭종은 내층이 비각화 편평 상피로 이루어져 있는 췌관의 낭성 확장을 특징으로 한다. 현재까지 이 질환은 재발이나 악성 변화가 관찰되지 않는 양성 질환으로 알려져 있다. 그러나 저자들은 수술 전 영상검사에서 타 장기 침습 의심 소견을 보이며, 수술 후 경과에서 악성 형태를 보이는 췌관의 편평세포낭종 1예를 경험하였기에 문헌고찰과 함께 보고한다.

The first comprehensive cladistic analysis of Miridae, the plant bugs, based on ~3000 base pairs of mitochondrial (COI, 16S) and nuclear (18S, 28SD3) genes, is presented. For 105 taxa (101 Mirid species in 7 subfamilies and 11 tribes, and 4 outgroups) in 7 subfamilies and 11 tribes of Miridae, the combined dataset was analyzed using ML (maximum likelihood), BC (bayesian criteria) and MP (maximum parsimony). Clades recovered in all analyses, comprise 6 main groups: Cimicomorpha and Miridae; Phylinae; Mirinae (Eurystylus + Polymerus + Proboscidocoris + Taylorilygus + Stenodemini); Orthotylinae; Mirini (Adelphocoris group except “Apolygus complex”); Apolygus complex; Deraecorinae; Bryocorinae + Isometopinae + Cylapinae. Our results indicate 1) the monophyletic relationships of two subfamilies Phylinae and Deraeocorinae within the family Miridae; 2) the paraphyly of subfamily Mirinae. Phylogenetic relationships at the tribal or subfamily level are provided in comparison with the prior studies based on morphological data.

The flower bugs (Heteroptera: Anthocoridae) is usually known as biological control agents against various kinds of agricultural pests such as aphids, mites, thrips and so on. Since the classification of the family Anthocoridae has been controversial, the molecular phylogenetic study was conducted with 44 species including 6 outgroup taxa. Three genes, a total of 3277 bp of sequence data (nuclear 18S rDNA: 2022bp, 28S rDNA: 755bp, and mitochondrial 16S rDNA: 498bp), were analyzed using ML (maximum likelihood) and Bayesian methods, excluding MP (maximum parsimony) as the incongruence length difference (ILD) test has very low (0.001) P-values on all partition tests. Our results support the rank and monophyly of the family Lasiochilidae which was exclusively separated from the main clade of Anthocoridae proposed by Schuh and Stys (1991), and indicate the monophyletic relationships among tribes and genera within the family Anthocoridae. According to our results, the genus Amphiareus should be out of the tribe Dufourini and treated as the tribe level and The three genera, Blaptostethus, Scoloposcelis and Xylocoris should be placed to the family Lyctocoridae. We also propose the evolutionary theory of Anthocoridae based on their habitats, hunting behavior and the molecular phylogenetic results.

Only two species of Eurydema occur in Korea and Japan: E. dominulus (Scopoli, 1763) [= E. pulchra (Westwood, 1837), syn. n.] and E. gebleri Kolenati, 1846 [= E. rugosa Motschulsky, 1861, syn. n.]. In order to prove the above taxonomical change, we focused on three major works (1)morphology, (2)molecular identification and (3)biological experiment (inter-specific copulation, confirmation of fertilization and interbreeding). All the results of these three major works support to confirm new taxonomical change amongst these four species. The inter-specific copulation occurs (E. pulchra_male X E. gebleri_female) in nature, but the eggs from inter-specific copulation are confirmed not to be fertilized as a result of the biological experiment. A new identification key to species occurring in Korea and Japan is presented for the all stages (from eggs to adult).
