신장이식은 환자의 삶의 질을 높이고 거의 정상적인 사회생활을 가능하게 함으로써 말기신부전 환자의 3가지 신대체 요법(혈액투석, 복막투석, 신장이식) 중에 가장 효과적이고 각광받는 치료법이라 할 수 있다. 최근 들어 의료기술과 의학의 발달로 신장이식의 성공률은 과거에 비해 비약적으로 높아지고 있으며 국내에서도 점차 신장이식수술을 받는 환자가 증가하고 있으나 서울이나 다른 대도시에 비해 의료환경이 열악한 중소도시나 지방의 병원에서는 아직도 시행하지 못하고 있는 형편이다. 이에 저자들은 경북 최초로 자체 의료진에 의해 고혈압과 말기 신부전으로 동국대 포항병원에서 혈액투석을 받고 있던 32세의 남자환자에게 부인으로부터 신장을 제공받아 신장이식을 성공적으로 시행하였기에 문헌고찰과 함께 보고하고자 한다. Kidney transplantation is the preferred treatment modality for many patients with end-stage renal disease (ESRD), because it offers improved quality of life over both hemodialysis and peritoneal dialysis. Patients who do well after transplantation generally report improvement in vitality and freedom to return to the style of life that they experienced before their progression to ESRD. Recently, the success rate of kidney transplantation is greatly being increased as the surgical technique and immunosuppressive drugs are developed. Kidney transplantation is also popular in Korea which has good result. But, until now the general hospitals which are located at small city can't try the kidney transplantation because they don't have proper facilities and experts. We firstly experienced a case of kidney transplantation in a 32 years old man with hypertension and chronic renal failure at KyoungBuk province. So we report this case with references.

과립상 세포종은 Schwann 세포 기원으로 생각되며 인체에 비교적 드물게 발생한다. 과립상 세포종은 전신 어느 곳에서나 발견될 수 있으나 주로 혀, 구강, 피부 혹은 유방 등에서 호발하며 드물게 위장관에서 발견된다. 위장관에서는 식도에서 가장 호발하며 다음으로 위, 대장 순이다. 과립상 세포종은 대부분, 특히 위장관에서는 양성이며 소수의 악성 병변이 보고되었다. 이러한 이유와 함께 수술 전의 진단이 어렵기 때문에 과립상 세포종에 대한 근본적인 치료는 현재까지 외과적 절제술이다. 최근에 시도되는 치료방법들로는 내시경적 레이저 치료, 용종절제술, 내시경적 점막 절제술 등이 있다. 저자들은 상부 소화관 내시경검사를 시행하여 식도 과립상 세포종을 진단하고 내시경적 점막 절제술을 시행하여 합병증 없이 퇴원하여 현재 재발없이 경과 관찰중인 1례를 경험하였기에 보고하는 바이다. Granular cell tumors, which occur infrequently, are probably of Schwann cell origin. They can occur almost anywhere in the body but usually affect the tongue, oral cavity, skin, or breasts and are rarely found in the gastrointestinal tracts. The esophagus is the most frequent gastrointestinal site, followed by the stomach and the colon. Granular cell tumors are generally benign, especially in the gastrointestinal tract, some malignant lesions have been reported. For this reason, and also because preoperative diagnosis is difficult, the standard treatment for granular cell tumor has until now been surgical excision. In recent years, other therapeutic methods is endoscopic laser therapy (ELT), polypectiomy, endoscopic mucosal resection (EMR). We report a case of esophageal granular cell tumor which was diagnosed by an endoscopy and managed using an endoscopic mucosal resection without complication.

Presently, We have constructed an olig-d(T) primed directional cDNA library from the silkworm Dongchunghacho, an entomopathogenic fungus, of which species is belonging to Paecilomyces tenuipes Jocheon-1. To isolate and screen genes in the fungus, 626 expressed sequence tags(ESTs) were generated by a partial sequencing from the cDNA library. Paecilomyces tenuipes Jocheon-1 cDNA encoding the glyceraldehyde-3-phosphate dehydrogenase(Pt-GAPDH) of Paecilomyces tenuipes Jocheon-1 was cloned from the above cDNA library. The complete cDNA sequence of Pt-GAPDHis comprised of 1,014bp encoding 338 amino acid residues. The deduced protein sequence of Pt-GAPDH showed higher homology with Beauberia bassiana-GAPDH(93% amino acid identity). Hydropathy analysis revealed that Pt-GAPDH protein is hydrophilic. The major three amino acids in its composition of amino acid residues were alanine(11.54%), valine(9.47%) and glycine(8.88%). The cDNA encoding Pt-GAPDH was expressed as a 37 kDa polypeptide in baculovirus-infected insect Sf9 cells. The Pt-GAPDH gene of Paecilomyces tenuipes entomopathogenic fungus consisted of three exons and two introns coding for 338 amino acid residues, and the genomic DNA length of the gene spans 1302bp. The accession number of the gene in GenBank are GU997099 for Pt-GAPDH cDNA and GU997102 for Pt-GAPDH genomic DNA.

Fungi belonging to the Paecilomyces spp. have recently been used as food and herbal medicines in Korea and are greatly popular as commercially available powdered supplement or dried fruiting body. Despite this acceptance and its use, little is known of the genes related to its reactive agents. Presently, We have constructed an olig-d(T) primed directional cDNA library from the silkworm Dongchunghacho, an entomopathogenic fungus, of which species is belonging to Paecilomyces spp. based on the previous identification of ITS1 and ITS2 at the molecular level and collected from Jocheon Miryang, Korea. To isolate and screen genes in the fungus, 626 expressed sequence tags(ESTs) were generated by a partial sequencing from the cDNA library. cDNA encoding the glyceraldehyde-3-phosphate dehydrogenase(Pt-GAPDH) of Paecilomyces tenuipes- Jocheon was cloned from the above cDNA library. The complete cDNA sequence of Pt-GAPDH is comprised of 1,014bp encoding 338 amino acid residues.

Hybridoma producing monoclonal antibodies reactive with the β-chain of interleukin-2 receptor (IL-2R) were generated from mice immunized with a synthetic peptide of 19 amino acids. The synthetic peptide constitutes strongly hydrophilic region of extracellular domain of the IL-2R molecules(residues 32-50) as revealed by hydrophathy plot analysis. Hybridomas were screened by ELISA using Hut102 cells and the synthetic peptide as antigenic moiety, and by miasuring the binding activity of antivodies to the Hut102 cell surface that was monitored by a flow cytometer. The antibodies were further screened by their inhibitory effect against the interaction between IL-2R and interleukin-2(IL-2). Antibodies were further characterized by immunoprecipitation followed by autoradiography to reveal that the antibodies recongnize the 75 KD protein molecules expressed on the Hut102 cell surface and human peripheral blood mononuclear cells(PBMC) shich confirms the antigenic moiety to be β-chain of IL-2 recepter molecules.

생리적 치근 흡수가 뒤따르는 유치 치주인대의 신경분포 및 변화를 평가하기 위하여 생후 1, 2, 3, 4, 5개월된 개의 유치 치주인대와 9개월된 영구치 치주인대를 대상으로 neurofilament protein(NFP)을 이용한 면역조직화학적 방법으로 관찰하여 다음과 같은 결과를 얻었다. ● 유견 유치의 치주인대 신경분포는 치근단 1/3부위에서 가장 밀집되어 있었으며 치근 중앙부로 향할수록 현저하게 감소되었으며 전체적으로 그 분포밀도 및 분지 정도는 영구치와 비교시 약한 양상을 나타냈다. ● 구치부에 비해 전치부에서 신경분포가 보다 발달된 양상을 보였으며 구치 치근이개부치주인대에서는 신경섬유가 관찰되지 않았다. ● 유치근이 흡수됨에 따라 신경분포 정도도 감소되었으며 탈락시기의 치근 주위에서는 신경섬유룰 관찰할 수 없었다. ● 치은점막상피의 신경지배는 치아가 발육함에 따라 감소되는 양상을 나타내었으며 설측점막이 순측점막보다 더 발달된 신경분포양상을 관찰할 수 있었다. ● 유치 치주인대 신경말단 형태는 수지상의 신경말단 형태를 나타내고 있었으며 전형적인 Ruffini 신경말단은 거의 관찰할 수 없었다. 이상의 결과를 미루어 신경섬유의 분포는 기능과 밀접한 관계가 있는 것으로 생각되고 더욱이 유치의 생리적 치근흡수에 따른 치주인대에 신경섬유의 분포 및 변화는 유치의 성장발육에 따른 하나의 변화라고 생각된다. The purpose of this study was to investigate the distribution of nerves in the periodontal ligament of a dog's primary teeth by each developing stage. The distribution of nerves in the periodontal ligament were investigated by means of immunohistochemistry for detection of neurofilament protein(NFP). The results were as follows: The NFP-immunoreactive nerve fibers were found to be densely distributed in the apical third of the periodontal ligament, while they were sparse in the coronal two third, in both primary and permanent teeth. In generally the density of distribution and degree of arborization of nerve fibers in periodontal ligament of primary teeth revealed a poor appearance compared with that of permanent teeth. Periodontal ligament in anterior teeth showed more abundant nerve innervation than posterior teeth, and the periodontal ligament of the bifurcation area in posterior teeth roots were not observed to have nerve fiber. The density of nerve distribution in the periodontal ligament of primary teeth was reduced according to the physiological root resorption and nerve fibers were not observed in the surrounding area on the root of the exfoliation stage in primary teeth. The distribution of nerve fibers in mucogingival tissue, was poor innervated according to the aging of the dogs. A more abundant distribution of nerve fiber was represented in the lingual mucogingival tissue than in the labial side. Most of the nerve endings in the periodontal ligament of primary teeth showed a tree-like appearance. However, the typical Ruffini-like nerve endings were not observed.

In this paper, we propose the hybrid system identification model and control method using neural networks. Proposed control method performs, for a nonlinear plant with unknown functions, system identification using an adaptive wavelet in a neural network, and then a nonlinear controller is designed with those identified informations. To identify a nonlinear function, which is not directly related to input signals, we can use an adaptive wavelet in three-layed neural network. In order to verify the usefulness of the proposed method, we simulate the proposed control method with cart pole system.

The purpose of this study was to investigate the kinematic variables of the lower extremity during the Soccer In-step shooting motion. To conduct an investigation, five soccer players(skill group) and five students(less-skill group) in the high school were participate in this study. They were videotaped using three video cameras with the frame rate being 60㎐. This data was then reducted to 3D coordinates using the DLT(direction linear transformation)method. It was concluded that; Medio-lateral(X) displacement of the skill group was larger than that less-skill group and antero-posterior(Y) displacement of the skill group was smaller than that less-skill group. Velocity transfer of the skill group was more effectiveness than less skill group. The sequence of the maximal joint velocity of the kicking leg was the hip, knee, and ankl joint. It is considered very important that the sequence of the laximal joint velocity is from the proximal to the distal in order to increase the foot velocity at the impact. Trunk angle of the skill group was smaller than that less-skill group. And then ankle joint angle of the skill group was larger than that less-skill group.
