  • Comparative karyological analyses of the Korean land snail, Diplommatina (Sinica) paxillus and Diplommatina (Sinica) changensis, were peformed by the Giemsa-staining and air-drying method. The karyotypes of both species were the same (2n = 26). However, the chromosome lengths and arm ratios, and relative chromosome lengths of the two species were distinctly different.

  • The lactate dehydrogenase isozymes in tissues of eight fresh water fishes were examined by cellulose acetate electrophoresis. The electrophoretic distribution of the isozymes showed clearly species-specific pattern. Various subbands were found more frequently in these fishes than in mammals. The isozyme pattern of muscle seems to tend to be the same with that of brain in these fishes. The fish lactic dehydrogenase suggested in many cases to be consisted of nonrandomly selected hybrids.

  • Recent heterogeneous network management researches on information security, however, deal only with simple management using PKI and could not sufficiently address the different kinds of security problems that could arise in a heterogeneous network. Thus, various security requirements should first be satisfied and a security management protocol should first be developed to achieve a secure heterogeneous network. Hence, in this paper, various secure and effective heterogeneous network management that address security issues, which were merely a consideration in existing studies, are proposed. The proposed scheme for the protection of the user privacy is the central object and static middle objects of the process used to mutual authentication, also if communication between users is required 1-out-2 oblivious transfer to communicate by using secret communication, as well as the effectiveness and security conscious approach. Specially The proposed scheme is designed to enhance security and efficiency related to various services required in heterogeneous network, based on the reliable peripheral devices for TTP. Using Mobile device, which has been applied to electronic commerce transactions in existing schemes, this study also proposed an appropriate management scheme that is suitable for a dynamic environment and setting a temporary group to provide various services.

  • The pulmonary lymphomas were thought to originate in specialized lymphoid tissue that is associated with bronchial mucosa(bronchus-associated lymphoid tissue(BALT)), and they were categorized as mucosa-associated lymphoid tissue(MALT) lymphoma. MALT lymphoma consists of a monoclonal population of cell, in contrast to reactive lymphoid proliferation, which consists of polyclonal cells. Lymphoma arising from MALT(=MALToma) represents a distinct clinicopathologic features. It is usually localized 10 their original site for a long time and shows much more favorable prognosis than lymphoma at other site. Some MALT lymphoma could arise simultaneously or successively in different organ or that cells from MALT lymphoma might circulate and give rise to another lymphoma by homing in the MALT of another organ, such as breast, salivary gland, stomach etc, and can be multifocally disseminated or recurred. We report a case of low-grade B-cell lymphoma of the mucosa-associated lymphoid tissue(MALT) of the lung, which was confirmed by open lung biopsy, immunohistochemistry and PCR assay.

  • MDH and LDH isozymes of various tissues of serveral snakes which belong to Colubridae, Crotalidae and Viperidae were studied. MDH isozymes were appeared as two bands in all species. Four LDH isozymes were found inall species of Colubridae, Crotalidae and Viperidae. LDH isozymes of muscle and liver had fundamentally the same pattern. On the other hand, there were two LDH isozymes in the heart of all species and the pattern of heart LDH isozyme was reverse of the pattern in muscle. The pattern of LDH isozymes of stomach tissue can be thought as the same pattern with that of heart in all species, but in the stomach tissue of Crotalidae and Viperidae there were four LDH isozymes.

  • A cellulosse acetate electrophoretic survey of Korean Anura has revealed the presence of diverse lactate and malate dehydrogenase (LDH and MDH) isozymes. The pattern of LDH and MDH isozymes in the tissues of the central nervous system of the six species of Anura examined are species specific and differ from those of mammals and birds. Both Rana nigromaculata nigromaculata and Rana nigromaculata coreana have two molecular forms of LDH and MDH, respectively, with almost the same pattern. Whole brain homogenate of Rana temporaria shows also a maximum of only two LDH isozymes. Both Bufo bufo asiaticus and Bombina orientalis have five molecular forms of LDH with an entirely different spacing on the zymograms, whereas Rana rugosa has three. Two molecular forms of MDH are present in all animals examined and one band is shown in olfactory lobe and mixture of cerebellum and medulla oblongata of Rana nigromaculata nigromaculata.

  • A cellulose acetate electrophoretic survey of Korean Anura has revealed the presence of diverse lactate and malate dehydrogenase isozymes. The LDH and MDH isozymes in the tissues of the brain, heart, stomach, skeletal muscle and liver of the six species of Anura examined show the species specific patterns which differ from those of mammals and birds. Two isozymic forms of LDH and MDH exist in both Rana nigromaculata and Rana nigromaculata coreana, respectively, with almost the same pattern. LDH of Bombina orientalis has five isozymic forms, and that of Rana temporaria ornativentris contains four isozymes. Bufo sp. has 3 to 5, and Rana rugosa has 3 to 4 isozymic bands according to the tissues. MDH's of all animals have two isozymic forms with different spacing on the zymograms.

  • 결핵성 임파선염은 아직도 한국에서 많이보는 질환이며 젊은여자 성인 특히 아시아인이나 흑인에서 가장 흔하다. 이 질환은 두경부에 흔히 무통성으로 서서히 림프절이 커지는 양상을 보이나 인체내 결절이 있는 어디나 오며 종격동 결절에도 온다. scrofula(선통(腺病))는 다양한 종양, 비종양성 종괴, 감염질환 특히 경부임파선염 풍과 구별되야만 한다. 비록 병력, 역학, 임상양상 흉부 엑스선 그리고 결핵반응검사로써 만족할만한 진단을 내리지만 절제생검으로 조직 및 배양이 필요하기도 하다. 궤양이나 만성 누공 형성을 막기위해 부분생검이나 절개 및 배농은 반드시 피해야 한다. 치료는 항결핵화학요법이며 가끔 외과적 적출술이 약물요법과 더불어 요구되기도 한다.
