호산구성 담낭염은 비교적 드문 질환으로 다른 일반적인 원인의 담낭염과 비교하여 증상, 검사실 소견 및 이학적 검사에 있어 차이가 없어, 주로는 수술 후 진단하게 된다. 한편, 호산구성 방광염은 호산구성 담낭염과 마찬가지로 드 물게 발생하며 이 역시 조직학적 진단을 통해서만 확진된다. 본 저자들은 우상복부통증으로 내원하여 급성 담낭담 관염으로 담낭절제술 시행 후 호산구성 담낭염이 진단된 환자에서, 수술 후에도 경도의 말초혈액 호산구증가증의 지속과 만성 하부 요로 증상으로 인해 경요로방광조직검사 후 호산구성 방광염의 병발을 국내 최초로 확인하였고, 과호산구증가증후군으로 발현한 호산구성 담낭담관염 및 방광염 진단하에, 이에 대해 스테로이드 투약을 통해 증상 및 말초혈액 호산구증가증의 소실을 경험하였기에 문헌고찰과 함께 보고하는 바이다.

The bumblebee, Bombus ignitus (Hymenoptera: Apidae), is a valuable natural resource that is widely utilized for greenhouse pollination in South Korea. Understanding the magnitude of genetic diversity and geographic relationships is of fundamental importance for long term preservation and utilization. As a first step, we sequenced a partial COI gene of mitochondrial DNA (mtDNA) corresponding to the “DNA barcode” region and the complete internal transcribed spacer 2 (ITS2) of nuclear ribosomal DNA from 88 individuals collected in nine South Korean localities. The complete ITS2 sequences were longest among known insects, ranging in size from 2,034 bp ~ 2,052 bp, harboring two duplicated 112-bp long repeats. The 658-bp long mtDNA sequences provided only six haplotypes with a maximum sequence divergence of 0.61% (4 bp), whereas the ITS sequences provided 84 sequence types with a maximum sequence divergence of 1.02% (21 sites). The combination of the current COI data with those of published data suggest that the B. ignitus in South Korea and China are genetically a large group, but those in Japan can be roughly separated into another group. Overall, a very high per generation migration ratio, a very low level of genetic fixation, and no discernable hierarchical population were found to exist among the South Korean populations of B. ignitus, which suggests panmixia. This finding is consistent with our understanding of the dispersal capability of the species.

뻐ny studìes have shown the anti-proli ferative effects of irondeprivation on cancer cell s‘ but the effects 01' iron-chelators on oral cancer have not been clearly elucidated , To investigate the effects of an iron chelato r, desferrioxamine( 01"O).on the growth of ilIllTIortali zed human o1'al ke ratinocytes(IHOK), primary oraJ cancer cel ls(HN4)‘ metastatic oral cancer cell s(HN12) , and human skin keratìnocytes(HaCaT) in the MTr assay, three-dimensional(3D) raft cul tmes, Western blott ing, cell cycJ e analysis‘ nuclear staining‘ and cytochrome c expression for apoptosis s ig naling pathway were used OFO inhibited the growth of immortalized IHOK and HaCaT and mal ignant HN4 and HN12 keratinocytes in a time- and dose-dependent manner according to the MTT assay, The 3D organotypic cu l tu re also revealed that OF'O-treated cells showed less epithelial maturation, less surface keratinizati on‘ and de creased epithelia l thickness, The major mechanìsm of growth inhìbition with the micromolar 0 1"0 treatment was by the induction of apoptosis‘ which was supported by nuclear OAPI staining, ONA fragmentation analysis, and J10w cytometric analysis for sub-Gl phase ar rest and Annexin V-1"ITC stainìng, Furthermore‘ Bax expression in creased together with p53 and p21WAF1!CIPl, whìle the Bcl-2 expression decreased in the immortalized and malig nant keratinocytes treated with 01"0 , Time-dependent cytochrome c from mitochondria was observed in D1"O-treated [l-IOK and 0 1'머 cancel‘ ceJJ s, and was accompanied by the activation of caspase-3 in IHOK cells.

May-Thurner syndrome is associated with deep vein thrombosis resulting from chronic compression of the iliac vein against the lumbar vertebrae caused by the overlying common iliac artery. Stent insertion into the compressed lesion is used in treatment of May-Thurner syndrome. Various complications can occur during angioplasty while using a stent. Among these complications, shrinkage of the vein below the stent, a rare complication, was observed in our hospital during treatment of a patient with May-Thurner syndrome. Different complications can occur when venous angioplasty is performed, unlike that when arterial angioplasty is performed.

국내에서 육성된 178개 품종을 이용하여 12개 이삭형질에 대한 검토 결과는 다음과 같다. 통일형이 자포니카형보다 이삭길이는 길었고 이삭목은 두꺼웠다. 또한 수당립수, 총지경수, 2차 지경수, 2차 지경 총립수, 2차 지경 평균립수 및 1차 지경당 2차 지경수 각각에서 많았다. 반면에 자포니카형이 통일형보다 이삭추출은 양호하였고 1차 지경 평균립수도 약간 많았다. 12개 이삭형질 값을 가지고 평균 연결법을 이용하여 178개 품종을 대상으로 군집분석을 한
