문형배,정성오,문영회 圓光大學校 1994 論文集 Vol.28 No.2

Microwave를 이용하여 고정한 조직을 plastic 포매하여, 얻은 절편으로 조직화학 염색인 Hematoxylin-Eosin(H-E), periodic acid-Shiff(PAS), reticulum, Masson's trichrome(M·T)염색을 하고 통상적으로 이용되는 포르말린 고정법을 통한 조직표본에서 동일한 염색을 하여 세포의 형태학적 관찰과 염색성을 비교하고자 본 연구를 시도하여 다음과 같은 결론을 얻었다. 1.Microwave조사 시간이 짧고 최종온도가 낮을 수록 조직의 형태학적 소견은 전반적인 세포구조가 파괴되어 불량하고 염생성도 약하였다. 2.Microwave를 이용한 고정에서 최적온도는 장기에 따라 서로 다르며 간장조직은 조사시간 136초, 최종온도59±2℃신장조직은 조사시간 175초, 최종온도 69±2℃에서 세포의 구조가 가장 잘 보존되었고 염색성도 양호하였다. 3.장기별 최적조건에서 PAS, reticulum, Masson's trichrome염색시 결과는 일반적인 포르말린 고정을 한 조직에서 나타난 결과와 일치하였다. 이상의 결과로서 microwave를 이용한 고정방법은 장기별 최적조건이 서로 다르고 고정시간이 짧다는 장점과 다양한 조직화학적 염색에 있어서도 양호한 염색성을 보였으며 전반적으로 형태학적 구조가 잘 보존되었다. This study was undertaken to evaluate the effect of rapid heat fixation on specimens using microwave irradiation. Small portions of the liver and the kidney specimen were fixed by microwave irradiation and subsequently processed by plastic embedding for light microscopical study. The control specimens were fixed by 10% neutral buffered formalin and processed by same method as the experimental ones. Both were stained with hematoxylin and eosin, periodic acid-Schiff, reticulum and Masson's trichrome. The results were as follows: 1.The tissue structures were destroyed and staining property of cells was poor by microwave irradiation at low temperature. 2.The optimal condition of fixation was different in each tissues. For the liver it was 136 seconds microwave irradiation at 59±2℃, for the kidney it was 175 seconds microwave irradiation at 69±2℃. 3. When the specimens were fixed on optimal condition by microwave irradiation, the quality of fixation was as good as that of formalin fixation. Above results suggest that the fixation time can be shortened by microwave fixation.

<연구목적> HBx형질전환 생쥐에서 발생한 간세포암종의 발암과정에 종양유전자(H-rgs, c-myc)의 발현 정도를 조사하고자 하였다. <연구방법> 정상생쥐 12마리(4-18개월) 및 HBx 형질전환 생쥐 44마리(4-18개월)를 대상으로 포르말린에 고정하고 파라핀에 포매한 간 조직을 이용하여 면역조직화학적염색을 실시하였다. 실험군은 정상 부위, 이형성 부위 및 종양 부위로 구분하였으며, 종양 부위는 소결절성병변 부위와 간세 포암종 부위로 구분하였고, 이형성병변 부위는 이형성병변만 발견되는 부위, 소결절성병변과 동반된 이형성병변 부위 및 간세포암종과 동반된 이형성병변 부위로 구분하였다. <연구결과> H-rgs의 발현은 정상 간조직에 비하여 이형성병변 부위(P<0.05) 및 종양 부위(P<0.01)에서 증가하였으며, 소결절성병변 부위과 간세포암종 부위 사이에서는 간세포암종 부위에서 증가된 경향이었으나 통계학적으로 유의한 차이가 없었으며, 각 이형성병변 부위 사이에서도 유의한 차이는 없었다. c-myc의 발현은 정상 간조직 및 이형성병변 부위에 비해 종양 부위에서 증가하였으며(P<0.001), 소결절성병변 부위와 간세포암종 부위에서는 비슷하였고, 각 이형성병변부위 사이에서도 비슷하였다. <결론> HBx형질전환 생쥐에서 발생하는 간세포암종의 발생에 H-rgs는 이형성 변화를 일으키는 시기에 관여하며, c-myc은 이형성병변에서 암으로 이행하는 시기에 관여할 것으로 생각한다. Background: This experiment was designed for the expression of H-ras and c-myc in hepatocarcinogenesis of the HBx transgenic mice. Methods: Immunohistochemical stains in the paraffin embedded tissue of the liver were used for the detection of H-ras and c-myc in the 12 normal mice and 44 HBx transgenic mice of the 4-18 month old. Results: Expression of the H-ras was significantly increased in the dysplastic area (P<0.05) and tumor area (P<0.01) than in the normal liver. But there were no differences of H-ras expression between areas of microscopically identified hepatocellular carcinoma (MI-HCC) and grossly identified hepatocellular carcinoma (GI-HCC) and dysplastic areas among the only dysplastic areas, dysplastic areas with MI-HCC and GI-HCC. Expression of the c-myc was significantly increased in the tumor area (P<0.001) than in the normal liver and dysplastic area. But there were no differences of c-myc expression between areas of MI-HCC and GI-HCC, and dysplastic areas among only dysplastic areas, dysplastic areas with MI-HCC and GI-HCC. Conclusions: Our study suggests that H-ras is related to the dysplastic change and c-myc is related to the neoplastic change in the hepatocarcinogenesis of the HBx transgenic mice.

A recombinant human erythropoietin (rHuEPO) was administered intravenously at dosage levels of 0, 100, 500, and 2500 IU/㎏/day for a period of 13 weeks. There were no observed clinical signs and deaths related to treatment in all groups tested. Decreases in body weight gain and food consumption were observed only in males of 2,500 IU/㎏ group after 2 weeks. In hematological parameters, erythrocyte content, hematocrit values and hemoglobin concentration were dose-dependently increased in rHuEPO treated groups. The ratio between kidney weight and whole body weight was significantly increased in females of 500 and 2,500 IU/㎏ groups. The spleen weight was also increased in both sexes of 500 and 2,500 IU/㎏ groups. However, the absolute weight change of other organs was not observed. In histopathological examinations, the renal tubular basophilia was observed only in males and females of 2,500 IU/㎏ groups. From these results, it is concluded that the no-observed adverse effect level(NOAEL) of rHuEPO is 100 IU/㎏ in rats in the present study.

Two experiments were conducted to investigate the effects of molasses supplementation to silage materials in ensiling Galgeuntang (herbal medicine) meal on the quality of silage, and its palatability in Korean native goats. In experiment Ⅰ, molasses was added at the levels of 0, 0.5, and 1.0% to Galgeuntang meal with three replicates per treatment. In experiment Ⅱ, three 1.5-yr-old Korean native goats were used to measure palatability. In experiment Ⅰ, lactic acid contents in molasses treatments were significantly(p<0.05) higher, and pH and butyric acid contents were lower than those of non-molasses treatment. In addition, molasses treatment increased total microbial cell counts in MRS medium for lactobacillus, but decreased total microbial cell counts in PDA medium for fungi. Molasses supplementation to silage materials increased in vitro dry matter disappearance. Molasses supplementation tended to increase silage intake in Korean native goat (experiment Ⅱ), but the difference was not significant(p>0.05). It is concluded that molasses supplementation to silage materials in ensiling herbal medicine meal could improve its preservability and palatability, the higher the better.

부대동맥 림프절 또는 쇄골상부 림프절에 국한된 전이가 있는 재발성 자궁경부암 환자들의 예후에 관한 연구

최석철,문형배 동국대학교 의학연구소 1998 東國醫學 Vol.5 No.-

자궁경부암에서 림프절 전이가 병소의 재발이나 환자의 예후에 악영향을 미친다는 것은 주지의 사실이다. 그러나 자궁경부암으로 일차치료 후에 재발한 자궁경부암 환자들 중에서 부대동맥 및/혹은 쇄골상부 림프절에 전이가 있는 환자들의 임상적 특징 및 예후에 대해서는 잘 알려져 있지 않다. 따라서 본 연구는 자궁경부암으로 근치적 전자궁적출술 및 골반림프절 절제술이나 방사선치료 후에 재발한 환자들 중 부대동맥 및/혹은 쇄골상부 림프절에 전이가 있는 환자들의 임상적 특징 및 예후에 대해 알아보고자 하였다. 1991년 1월부터 1995년 12월 까지, 원자력병원 산부인과에서 자궁경부암으로 일차치료 후 전산화 단층촬영 및 세침흡인 세포검사에서 부대동맥 및/혹은 쇄골상부 림프절전이가 증명된 재발성 자궁경부암 환자 55명을 대상으로 하였다. 1. 대상환자 55례 중 부대동맥 림프절에 국한된 전이가 있었던 경우는 31례(56.4%)였으며, 쇄골상부 림프절에 전이가 있었던 경우는 24례(43.6%)였다. 쇄골상부 림프절에 전이가 있었던 24례 중 8례는 쇄골상부 림프절에 국한된 전이가 증명된 경우(Supraclavicnlar lynph node : SCLN only군)였고, 나머지 16례는 부대동맥 림프절 및 쇄골상부 림프절에 전이가 동시에 있는 경우(both군)였다. 2. FIGO 임상병기별 분포는 Ⅰ기 9.1%, Ⅱ기 56.4%, Ⅲ기 32.7%, Ⅳ기 1.8%였다. 세포형태에 따른 림프절 전이율은 편평상피세포형이 96%(53/55)였다. 대상환자 55례 중 22례(40.0%)는 일차치료 당시 이미 골반림프절에 전이가 있었던 경우였다. 대상 환자들의 원발암 치료는 방사선 치료만을 시행 받은 경우가 60.0%(33/55), 방사선 치료와 항암화학요법을 시행 받은 경우가 18.2%(10/55), 수술 및 방사선 치료, 항암화학요법을 시행 받은 경우가 18.2%(10/55), 그리고 수술 및 방사선 치료를 시행 받은 경우가 3.6%(2/ss)였다. 3. 전체 연구대상 환자 55례의 3년 생존율은 14.4%이었으며, 부대동맥 림프절전이군과 쇄골상부 림프절전이군의 3년 생존율은 각각 15.4%, 10.7%이었고, SCLN only군 및 both군의 3년 생존율은 각각 0%, 19.7% 이었다. 결론적으로, 쇄골상부 림프절 전이가 있는 환자는 부대동맥 림프절에 국한된 전이가 있는 환자보다 3년 생존율이 낮음을 알 수 있었으며, 이에 따라 재발성 자궁경부암 환자에서는 쇄골상부 림프절의 전이 유무가 환자의 예후를 추정하는데 중요한 지표가 될 것으로 생각되었다. It is evident from previous reports that in patients with cervical cancer with metastases to lymph nodes have unfavorable outcome, there are, however, few reports have previously been made of the clinical characteristics and prognosis of patients with metastasis limited to para-aortic lymph nodes(PALN) only versus supraclavicular lymph nodes(SCLN) following primary treatment. This paper attempts to discuss the outcome of Patients with recurrent cervical cancer metastasis limited to these lymph nodes. This report is a retrospective analysis of 55 patients with recurrent cervical cancer metastasis limited to para-aortic or supraclavicular lymph nodes following radical hysterectomy or definitive radiation therapy treated at the Korea Cancer Center Hospital, from January 1991 through December 1995. The results were as follows. 1. Of the 55 patients entered, 31(56.4%) had positive nodes on para-aortic area only and 24(46.3%) had positive nodes on supraclavicular area. 8 of 24 patients had limited metastasis to SCLN only and 16 had metastatic nodes on both para-aortic and supraclavicular area. 2. The distribution of patients according to initial FIGO stage were 9.1% in stage Ⅰ, 56.4% in stage Ⅱ, 32.7% in stage Ⅲ, and 1.8% in stage Ⅳ. In 96.4%(53/55) of cases, the histologic type was a squamous cell carcinoma. 22(40.0%) of 55 patients had pelvic lymph node metastasis at the time of initial treatment. The distribution of patients by treatment modalities prior to recurrence was 60.0%(33/55) for patients treated with radiotherapy alone, 18.2%(10/55) for patients treated with combined chemotherapy and radiotherapy, and 18.2%(10/55) for patients treated with combined surgery, radiotherapy, and chemotherapy. 3. The overall 3-year survival rate for patients with positive nodes on para-aortic or supraclavicular area was 14.4%; those who had lymph nodes limited to para-aortic only achieved 15.4%; those who had lymph nodes limited to supraclavicular lymph node achieved 10.7%. Of these, those who had nodes on supraclavicular lymph node only or both supraclavicular and para-aortic lymph node achieved 0% and 19.7% 3-year survival rate, respectively. In conclusion, the outcome for patients with metastasis to supraclavicular lymph nodes was worse than for patients with metastasis to para-aortic lymph nodes only. This suggest that the presence of metastatic carcinoma on supraclavicular lymph node may be a reliable Predictor of probability of survival in such patients.

신증후출혈열 환자의 혈청학적 및 분자생물학적 진단 검사법 비교

우영대,문희주,배형준 대한의생명과학회 2000 Journal of biomedical laboratory sciences Vol.6 No.2

우리나라에서 발생하고 있는 급성 출혈성 질환인 신증후출혈열의 원인 바이러스는 Family Bunyaviridae의 Genus Hantavirus에 속하는 한탄과 서울바이러스에 의하여 발생되고 있다. 본연구에서는 신증후출혈열로 의뢰된 환자에서 한탄바이러스에 대한 항체가를 간접면역형광항체법(indirect immunofluorescent antibody technique, IFAT), 면역효소측정법(enzyme-linked immunosorbent assay, ELISA) (IgG, IgM), 고비중입자응집반응(high density composite particle agglutination, HDPA) 및 플라크감소중화시험(plaque reduction neutrafization test, PRNT)등으로 비교 측정하였고, 신증후출혈열환자로 확진된 15명의 한타바이러스 혈청형을 PRNT와 혈청형 특이 역전사 효소 중합효소연쇄반응(nested reverse transcriptase polymerase chain reaction, nested RT-PCR)으로 확인하였다. 신증후출혈열로 의뢰된 환자에서의 한탄바이러스에 대한 IFAT, ELISA(IgG,IgM),HDPA 그리고 PRNT 비교에서 형광항체, ELISA IgG, 응집항체 및 중화항체는 8명 모두 높게 나타났으며, ELISA IgM은 5명에서는 현저히 높은 항체를 보유하고 있었다. 신증후출혈열 환자 15명에서는 높은 형광항체와 중화항체 역가를 나타내었고, 15명 중 12명은 한탄바이러스, 2명은 서울바이러스에 대한 높은 중화항체를 갖고 있었으며, 1명은 두 바이러스에 대하여 동일한 항체 역가를 나타내었으며, 혈청형 특이 primer를 사용한 nested RT-PCR에서는 15명 중 3명과 1명만이 한탄바이러스와 서울바이러스 primer에 대해 RNA가 검출되었다. The etiologic agents of haemorrhagic fever with renal syndrome(HFRS) in Korea are Hantaan and Seoul virus in the genus Hantavirus, family Bunyaviridae. Antibody titers of sera from HFRS patients against Hantaan virus were measured by immunofluorescent antibody technique(IFAT), enzyme-linked immunosorbent assay (ELISA), high density composite particle agglutination (HDPA) and plaque reduction neutralization test (PRNT). PRNT and nested reverse transcriptase polymerase chain reaction (nested RT-PCR) was used for serotypic differentiation of Hantaviruses against Hantaan and Seoul virus. Eight doubtful HFRS patients showed higher fluorescent, IgG ELISA, agglutination and neutralizing antibody titer by IFAT, ELISA IgG, HDPA and PRNT, respectively. Five out of them showed high IgM antibody titer by IgM capture ELISA against Hantaan virus, remarkably. Fifteen HFRS patients showed higher fluorescent antibody titer by IFAT. In PRNT, 12 out of them showed high neutralizing antibody titer aginst HTNV, 2 against SEOV and 1 against both viruses. In nested RT-PCR using serotype specific-primer, 3 out of them showed positive against HTNV and 1 against SEOV.
