'당뇨발'은 '당뇨환자에서 신경학적 이상이나 말초혈관 이상 때문에 발생하는 발의 궤양으로 감염이나 심부 조직의 파괴를 동반하기도 하는 발의 질병'이라고 정의할 수 있다. 하지만 실제로는 발에 궤양이 발생한 상태가 아니더라도 매우 포괄적인 용어(umbrella term)로서 당뇨병환자에게서 발생하는 발의 만성 합병증을 총칭하는 것이 일반적이다. 왜냐하면 발의 궤양을 동반하지 않는 괴저(괴사), 심부 감염, 신경병증성 관절증(Charcot arthropathy) 등도 당뇨발의 범주에 포함시켜야 하기 때문이다. 이렇게 보면 '당뇨발'이란 의학적 진단명으로는 적절하지 않은 용어라 할 수도 있다. 다만 이미 일반화된 용어로서 환자의 교육과 설명에는 더 유용하다고 할 수 있다.

황색인(Yellow phosphorus)에 대한 직업적 노출기준 TLV-TWA는 0.1 mg/㎥(0.02ppm)으로 권고하였다. 이 수준은 보고된 간경변증을 포함하여 호흡기 자극, 급성 중독인 전해질 불균형, 심근 붕괴 및 신장 피질 괴사의 가능성을 최소화하기 위한 것이다. 그러나 제한된 자료로 인중독성괴저(phossy jaw)와 같은 만성적 영향에 대한 보호 한계 수준을 설정하기에는 불확실하다. 입자 상태의 인(phosphorus)에 대한 노출은 예상되지만 증기압 수준을 감안할 때 증기에 대한 직업적 노출의 유해성을 내포하고 있다. 황색인은 가장 독성이 강한 무기 물질 중에 하나이다. 또한, 결정체 고체(crystalline solid)는 30℃ 이상의 온도에서 공기 중에 자발적으로 발화될 수 있으며, 독성이 높은 흄도 방출될 수 있다.

Pyoderma gangrenosum associated with ulcerative colitis is an unknown etiology of destructive skin disorder, characterized by progressive painful ulceration. It begins as a erythematous areola or pustule and rapidly progress into a deep ulceration with a discrete and violaceous edge. Early diagnosis followed with non-compressive moist dressing, topical application and systemic immunosuppressants are cornerstone in treating this disease. We report a case of pyoderma gangrenosum exacerbated with incision and drainage in a 15 year old girl with ulcerative colitis. This case emphasizes the importance of early consideration of pyoderma gangrenosum in patient with a background of related systemic disease and minimal traumatized wound care.

We have cloned and analyzed cDNA coding for non-virion (NV) protein of the m V - P R T The NV gene contained 336 bp open readmg frame and encoded a protein of 11 1 amino acids with a molecular weight of 13.2 kDa. The deduced amino acid sequence of NV of IHNVPRT was found to be 90-95% identical to those of foreign isolates of IHNV. These results indicate that NV gene of the MNV is highly conserved among &ifferent strains of THNV Northern blot analyses revealed that the levels of NV gene expression were strongly elevated after 20 h post-infection. In order to identify the role of NV in the replication of MNV in fish cells, IHNVinfected cells were treated with antisense oligonucleotides. While IHNV-PRT exposed to glycoprotein (G) antisense oligonucleotide showed severely reduced growth, the growth of virus exposed to NV antisense oligonucleotide was not affected by NV antisense oligonucleotide, which suggests that NV is not essential for replication of IHNV in fish cells.

A twenty six months-old boy developed hemophagocytic syndrome during the course of Kawasaki disease. Despite the appropriate treatment modalities for Kawasaki disease, he developed thrombocytopenia, hepatomegaly, high-grade fever, hypertriglyceridemia, peripheral gangrene, and evidence of hemophagocytosis in bone marrow biopsy. Although the course was stormy, he responded well to a combination therapy of corticosteroid and etoposide.

The larger segment of double stranded RNA genome from a new serotype of Infectious Pancreatic Necrosis Virus (IPNV), DRT, has been partially cloned at Sma I site in pUC19 and compared with the restriction maps of VR-299 and Sp. Restrction sites found in DRT was distinct and hence a new serotype. The cDNA clones of DRT were about 800, 850, and 1, 400 bp long each and do not share any common restiction site. It is not clear yet if there exist any overlapping sequences among them. This partial cloning, however, was sufficient for the comparison of restriction maps with the other serotypes.

Two viruses were isolated from kidney and spleen tissues of goldfish(Carasius auratus) and the ovarian fluid of chum salmon(Oncorhynchus keta). Both viruses replicated and produced cytopathic effect in EPC, CHSE-214, and CHH-1 cell lines at $15^{\circ}C$. The isolates were resistant to pH 3 and choloroform. Antiserum to infections pancreatic necrosis virus(IPNV) serotype VR 299 neutralized the infectivity of both of the isolates. Electron microscopy showed that the particles had typical IPNV particle morphology with average diameters of 55nm, This paper describes the first isolation of viruses infecting cultured fish in Korea.

In order to identify the characteristics of a Korean isol ate of infectious hematopoietic necrosis virus(IHNV), IHNV-PRT, we have cloned and analyzed cDNAs coding for matrix protein M1 and M2 of the IHNV-PRT. The Ml gene contained 693 bp open reading frame and encoded a protein of 230 amino acids with a molecular weight of 25.9 kDa. The M2 gene had 588 bp open reading frame, encoding a protein of 195 amino acids with a molecular weight of 21.9 kDa. On the deduced amino-acid sequences, M1 and M2 of the IHNV-PRT were found to be 92-93% (M1) and 97% (M2) identical to those of foreign isolates of IHNV. These results indicate that M genes of the IHNV are highly conserved among different strains of IHNV.

We have cloned and analyzed cDNA coding for nucleocapsid protein N from infectious hematopoietic necrosis virus(IHNV), IHNV-PRT, which was isolated in Korea. The N gene had open reading frame of 1,176 bp that encoded a 391 amino acids with a molecular weight of 42.3 kDa. The deduced amino acid sequence of N protein was 75-90% identical to those of foreign isolates, IHNV, but was 43% and 38% identical to those of other species of fish rhabdovirus, hirame rhabdovirus(HRV) and viral hemorrahagic septicemia virus(VHSV), respectively. However, it revealed high levels of sequence identity between 214-265 amino acid sequences among all species of fish rhabdovirus.
