이유나(Lee You-Na) 한국기독교역사연구소 2017 한국기독교와 역사 Vol.- No.46

본 연구는 이태영이 가족법개정운동을 주도해 나간 배경과 과정에 대해 검토하였으며, 가족법개정운동을 통한 과정 속에서 여성문제에 대하여 어떻게 사고하였는지 검토하였다. 또한 이태영이 인권운동과 민주화운동에 참여한 배경과 과정 및 역사적 의미에 대해 살펴보았다. 평북 운산에서 출생한 어린시절부터 받은 독실한 기독교적 가정교육과 학교교육은 훗날 가족법개정운동을 통한 여성인권운동에 힘을 쏟게 한 그의 만인평등사상과 남녀 평등의식의 형성에 영향을 주었다. 이태영은 시대적 선구자적 사명감으로 여성법률상담소를 설치하여 운영하였으며, 법의 보호를 받아야 할 여성이 오히려 법 때문에 억울함을 당하는 경우가 많아 법 자체부터 수정이 필요하다는 생각에서 여성인권운동으로서 가족법개정운동에 나섰던 것이다. 또한 이태영은 여성문제 해결을 위해서는 여성 자신이 과거의 잘못된 인습과 제도로부터 독립하려는 자각이 무엇보다 중요하며 여성교육을 통한 지적향상을 추구해나갈 뿐만 아니라, 여성들도 정치적, 사회적인 참여를 확대해 나갈 것을 역설하였다. 그리고 이태영의 미국연수시절에서의 경험은 국내에 들어와 가정법원의 설치와 이대 법학과의 법률임상실습 교육의 실시에 큰 영향을 끼쳤다. 이태영의 여성운동은 여성인권운동에만 그치는 것이 아니라, 궁극적으로는 남자와 여자의 인권을 동시에 추구하는 인권으로 확대 발전시켜 사고하였으며, 더 나아가 이 땅에 평화와 민주주의를 실현하기 위한 것이었다. 이태영은 감시와 탄압으로 민주회복국민회의가 반유신운동을 전개해나가는데 어려움이 많았음에도 이 나라의 민주회복을 위해 매우 적극적으로 활동하였다. 그리고 3.1민주선언사건 시기에도 재야 지식인, 종교인, 정치인들과의 협력 속에서 정치적 민주화를 위해 묵묵히 배후에서 지원하였다. 또한 이태영은 인권문제의 해결을 위해 인권문제협의회, 한국기독교교회협의회의 인권위원회 등에서 전문위원으로 활동하는 등 인권운동에 활발히 참여하였다. This study examined the background and process of Lee"s initiative to revise the family law, I examined how she thought about women"s issues in the course of the family law revision movement. I also looked at the background, process and historical meaning of Lee"s participation in the human rights and democratization movement. The devout Christian family education and school education that Lee Tae-young born in Pyongbuk province from childhood influenced the formation of his universal equality idea and gender equality consciousness which led to Lee"s efforts to promote the women"s rights movement through the revision of the family law in the future Lee Tae-young has established and operated a women "s legal counseling center with a pioneering sense of duty for the times. Women who are supposed to be protected by the law are often victimized by the law, and therefore she has begun the amendment of the family law as a women"s rights movement in the sense that the law itself needs revision. She also argued that women"s self-awareness of women"s independence from past wrong conventions and institutions is more important than any other. She emphasized not only pursuing intellectual advancement through women"s education, but also expanding women"s political and social participation. Lee Tae-young"s experience in the United States during the US training period has had a great impact on the establishment of the Family Court and the implementation of legal clinical training education at Ewha Womans University Law School. Lee thought not only the women"s rights movement but also the human rights movement that pursues the human rights of both men and women at the same time. Her women"s movement was further to realize peace and democracy on this land. Lee acted very actively for the democratic recovery of the country despite the difficulties of the Democratic Recovery People"s Congress due to surveillance and repression. And at the time of the 3.1 Democracy Declaration, in the cooperation with the intellectuals, religionists, and politicians in the field, she supported in the background for political democratization. In addition, Lee actively participated in human rights campaigns such as the Human Rights Council and the Human Rights Committee of the Korea Christian Church Council.

초고온성 고세균 Thermococcus onnurineus NA1은 개미산, 일산화탄소, 또는 전분 등을 이용해서 수소를 생산하는 것으로 알려져 있다. 본 연구에서는 T. onnurineus NA1의 고정화 세포를 이용한 수소생산을 고찰하였다. 고정화 실험결과, T. onnurineus NA1은 표면에 아민기가 코팅된 규조토 담체에 정전기적 인력에 의해 효과적으로 고정화되었고, 1 g의 담체에 고정화 될 수 있는 최대 세포의 양은 71.7 mg-dcw로 확인되었다. 고정화 세포를 이용한 세 번의 반복회분식 배양을 통해 개미산으로부터 수소생산 특성을 고찰하였고, 그 결과 배양이 반복됨에 따라 고정화 세포 농도의 증가에 기인하여 초기수소생산속도가 2.3 에서 4.0 mmol l⁻¹ h⁻¹로 상당량 증가됨이 관찰되었다. 따라서, T. onnurineus NA1의 고정화세포 시스템은 수소생산을 위한 좋은 대안이 될 수 있을 것으로 사료된다. 본 연구는 초고온성 고세균의 고정화세포를 수소생산에 적용한 첫 번째 사례이다. Previously we reported that the hyperthermophilic archaeon, Thermococcus onnurineus NA1 is capable of producing hydrogen (H₂) from formate, CO or starch. In this study, we describe the immobilization of T. onnurineus NA1 as an alternative means of H₂ production. Amine-coated silica particles were effective in immobilizing T. onnurineus NA1 by electrostatic interaction, showing a maximum cell adsorption capacity of 71.7 mg-dried cells per g of particle. In three cycles of repeated-batch cultivation using sodium formate as the sole energy source, immobilized cells showed reproducible H₂ production with a considerable increase in the initial production rate from 2.3 to 4.0 mmol l⁻¹ h⁻¹, mainly due to the increase in the immobilized cell concentration as the batch culture was repeated. Thus, the immobilized-cell system of T. onnurineus NA1 was demonstrated to be feasible for H₂ production. This study is the first example of immobilized cells of hyperthermophilic archaea being used for the production of H₂.

Aims: Tenofovir disoproxil fumarate (TDF) is considered as the preferred treatment option for chronic hepatitis B (CHB) patients with treatment failure or resistance to prior nucleos(t)ide analogues (NAs) treatment. We investigated the efficacy of long-term TDF-based therapy in CHB patients with previous NAs-experience. Methods: This study included total 251 patients who had previous history of NAs therapy and were treated with TDF mono (n=173) or TDF combined with other NA (n=78) from August 2012 to March 2017. Virologic response (VR) was defined as undetectable serum HBV DNA by PCR (<20 IU/mL). Results: Mean age of patients was 49.3 years, median duration of TDF therapy was 27.2 months, 75.7% were HBeAg-positive, and median HBV DNA was 3.7 log10IU/mL. The cumulative rates of VR were 188/244 (77.0%), 180/211 (85.3%), and 146/161 (90.7%) at 12, 24, and 36 months, respectively. Multivariate analysis showed that body mass index (OR 0.77, 95% CI 0.61-0.95, p=0.0189) and duration of TDF therapy (OR 1.09, 95% CI 1.02-1.18, p=0.0221) was significantly associated with VR. TDF monotherapy, HBeAg-positivity, platelet count, serum albumin was associated with VR in the univariate analysis, but not significant in the multivariate analysis. In relation to renal safety, patients showed renal impairment (7, 3.0%), mild hypophosphatemia (15, 7.2%), severe hypophosphatemia (1, 0.4%). Conclusions: Long-term TDF-based therapy demonstrated highly effective in viral suppression and relatively favorable renal safety in CHB patients with previous NA-experience. The body mass index and duration of TDF therapy was independent factors associated with VR.

Aims: Tenofovir (TDF) entecavir (ETV) are considered as the preferred treatment options for treatment-naïve chronic hepatitis B (CHB) patients. We compared the virologic response and renal safety of long-term TDF versus ETV therapy in naïve CHB patients. Methods: This retrospective study included total 432 patients who were treated with TDF (n=205) or ETV (n=227) from August 2012 to March 2017. Virologic response (VR) was defined as undetectable serum HBV DNA by PCR (<20 IU/mL). Results: Mean age of patients, sex, baseline serum levels of AST, ALT, creatinine, and HBV DNA were not significantly different between TDF and ETV groups. The cumulative rates of VR between TDF and ETV groups were 71.6% vs. 61.8% (p=0.477), 88.1% vs. 79.6% (p=0.058), and 84.8% vs. 83.7% (p=0.966) at 1, 2, and 3 years, respectively. The cumulative rates of genotypic resistance between TDF and ETV groups were 0% vs. 0%, 0% vs. 1.5% (p=0.404), and 0% vs. 2.2% (p=0.447) at 1, 2, and 3 years, respectively. Incidences of renal impairment and hypophosphatemia during treatment up to 3 years were not significantly different between two groups. Multivariate analysis showed that HBeAg-positivity (OR 0.27, 95% CI 0.12-0.58, p=0.0012) and serum HBV DNA at 1 year 2000 IU/mL (OR 0.09, 95% CI 0.03-0.25, p<0.0001) were significantly associated with VR. Conclusions: Long-term TDF and ETV treatments appear to have similar virologic response and renal safety in naïve CHB patient. However, long-term ETV therapy might to be associated with genotypic resistance in 2.2% up to 3 years, while none of patients on TDF therapy did.

배경 : 임상에서 흔히 사용하는 이뇨제 furosemide는 비후상행각에서 Na+-K+-2CI- cotranspoter (NKCC2)를 억제하여 NaCl 재흡수를 차단하여 이뇨작용을 나타낸다. Furosemide를 장기간 투여하면 내성과 대사성 알카리증의 부작용이 발생할 수 있는데, 이는 집합관에 도달하는 소디움 증가와 관련 있을 가능성이 있다. 방법 : 저자들은 furosemide의 내성이나 부작용이 집합관 상피 소디움 통로 (ENaC) 단백발현의 변화와 관련이 있는지를 확인하고자, Sprague-Dawley rat에서 farosemide (12 mg/day)을 7일간 지속적 피하 주입한 후 반정량적 immunoblotting과 면역조직화학법을 이용하여 NKCC2, Na +-CL- cotransporter (NCC), ENaC 단백의 발현을 관찰하였다. 실험기간 동안 수분과 전해질 용액 (0.8% NaCl & 0.1% KCl)을 자유롭게 섭취하도록 하여 체액 감소를 방지하였다. 결과 : 부형약 (vehicle)을 투여한 대조군에 비하여, furosemide를 투여한 군에서 각각 요량과 요 소디움 배설이 증가하였으나, 체중, 혈청 알도스테론치 및 크레아티닌 청소율은 차이가 없었다. Furosemid 투여 후 NKCC2 단백은 피질 (151±10 vs. 100±10%, p<0.05)과 외수질 (122±5 vs. 100±3%, p<0.01)에서 증가해 있었다. ENaC 단백은 세 가지 subunit 모두 furosemide 투여 후 대조군에 비하여 피질 (α:187±25 vs. 100±22%, p<0.05; β:155±8 vs. 100±15%, p<0.05; γ:168±16 vs. 100±9%, p<0.05)과 외수질 (α:171±27 vs. 100±17%, p<0.05; β :986±91 vs. 100±33%, p<0.01; γ :242±24 vs. 100±22%, p<0.01)에서 증 가하였다. 면역조직화학법에서도 furosemide를 투여한 군의 집합관 주세포에서 ENaC β-subunit가 더 강하게 염색되었다. 결론 : 이상에서 장기간 furosemide 투여시 집합관 ENaC 발현이 증가하며, 이러한 원위부네프론의 적응 반응이 이뇨제 내성을 유발하는데 기여할 것으로 생각한다. Background : Furosemide inhibit NaCl absorption in the thick ascending limb and produce an increase in distal delivery of Na+. We carried out semiquantitative immunoblotting and immunohistochemistry of rat kidneys to investigate whether chronic furosemide infusion is associated with compensatory increases in the abundance of Na+ transporters in distal nephron. Methods : Osmotic minipumps were implanted into Sprague-Dawley rats to deliver 12 mg/day of furosemide(n=6) with simultaneous administration of 0.8% NaCl and 0.1% KCl in drinking water for 7days. Results : Compared with vehicle infused controls, urine volume and urine sodium amount were increased. However, there were no differences in body weight, serum aldosterone, and creatinine clearance. The abundance of Na+-K+-2CI - cotransporter after furosemide infusion was increased in cortex (151±10 vs. 100±10%, p<0.05) and outer medulla (122±5 vs. 100±3%, p<0.01). In furosemide infusion group, the abundance of all three subunits of epithelial sodium channel (ENaC) was increased both in cortex (α:187±25 vs. 100±17%, p<0.05; β:155±8 vs. 100±15%, p<0.05; γ :168±16 vs. 100±9%, p<0.05) and outer medulla (α:171±27 vs. 100±17%, p<0.05; β :986±91 vs. 100±33%, p<0.01; γ :242±24 vs. 100±22%, p<0.01). Consistent with these results, ENaC β-subunit immunohistochemistry showed a remarkable increase in immunoreactivity in the principal cells of collecting ducts with furosemide treatment. Conclusion : These increases in the abundance of ENaC protein may account for the generation of diuretic tolerance.

Are Spinal GABAergic Elements Related to the Manifestation of Neuropathic Pain in Rat?

Jaehee Lee,Seung Keun Back,Eun Jeong Lim,Gyu Chong Cho,Myung Ah Kim,Hee Jin Kim,Min Hee Lee,Heung Sik Na 대한생리학회-대한약리학회 2010 The Korean Journal of Physiology & Pharmacology Vol.14 No.2

Impairment in spinal inhibition caused by quantitative alteration of GABAergic elements following peripheral nerve injury has been postulated to mediate neuropathic pain. In the present study, we tested whether neuropathic pain could be induced or reversed by pharmacologically modulating spinal GABAergic activity, and whether quantitative alteration of spinal GABAergic elements after peripheral nerve injury was related to the impairment of GABAergic inhibition or neuropathic pain. To these aims, we first analyzed the pain behaviors following the spinal administration of GABA antagonists (1Ռg bicuculline/rat and 5Ռg phaclofen/rat), agonists (1Ռg muscimol/rat and 0.5Ռg baclofen/rat) or GABA transporter (GAT) inhibitors (20Ռg NNC-711/rat and 1Ռg SNAP-5114/rat) into naïve or neuropathic animals. Then, using Western blotting, PCR or immunohistochemistry, we compared the quantities of spinal GABA, its synthesizing enzymes (GAD65, 67) and its receptors (GABA_A and GABA_B) and transporters (GAT-1, and -3) between two groups of rats with different severity of neuropathic pain following partial injury of tail-innervating nerves; the allodynic and non-allodynic groups. Intrathecal administration of GABA antagonists markedly lowered tail-withdrawal threshold in naïve animals, and GABA agonists or GAT inhibitors significantly attenuated neuropathic pain in nerve-injured animals. However, any quantitative changes in spinal GABAergic elements were not observed in both the allodynic and non-allodynic groups. These results suggest that although the impairment in spinal GABAergic inhibition may play a role in mediation of neuropathic pain, it is not accomplished by the quantitative change in spinal elements for GABAergic inhibition and therefore these elements are not related to the generation of neuropathic pain following peripheral nerve injury.

De novo Hyponatremia in Patients Undergoing Peritoneal Dialysis: A 12-month Observational Study

( Hyun Hee Lee ),( Soo Jung Choi ),( Heon Nam Lee ),( Sun Young Na ),( Jae Hyun Chang ),( Woo Kyung Chung ),( Se Joong Kim ) 대한신장학회 2010 Kidney Research and Clinical Practice Vol.29 No.1

Purpose: Hyponatremia occurs infrequently in patients undergoing peritoneal dialysis (PD). Nevertheless, one must understand its pathophysiology, since the therapeutic strategy differs from that of non-PD-related hyponatremia. This study examined the clinical features of hyponatremia in PD and evaluated the factors that may contribute to its development. Methods: We retrospectively enrolled 51 normonatremic PD patients at Gachon University Gil Hospital, South Korea. Using the plasma sodium levels at month 13, the patients were divided into hyponatremia (Na+<135mEq/L) and normonatremia (Na+≥135mEq/L) groups. Then, the clinical variables of these patients were examined, including peritoneal function and adequacy tests, and biochemical parameters. Results: The de novo hyponatremia (n=8) and normonatremia (n=43) groups had no significant differences in baseline characteristics. At month 1, the serum albumin was lower in the hyponatremia group (p=0.022). In the peritoneal equilibration test analysis, the dialysate-to-plasma ratio for creatinine (D/Pcr) measured after 13 months differed significantly between the two groups (p=0.007), while the maximum dip in sodium did not differ. No significant differences were observed in the normalized protein equivalent of nitrogen appearance, Kt/V, or residual renal function. Conclusion: Our data suggest that the development of hyponatremia is associated with a lower initial serum albumin level and increased D/Pcr in patients undergoing PD. Therefore, the serum sodium levels should be monitored more carefully in these patients.

Original Articles : Effect of aldosterone on the amplification of oncolytic vaccinia virus in human cancer Lines

( Hyun Ju Lee ),( Ja Sung Rho ),( Shao Ran Gui ),( Mi Kyung Kim ),( Yu Kyoung Lee ),( Yeon Sook Lee ),( Jeong Eun Kim ),( Eu Na Cho ),( Mong Cho ),( Tae Ho Hwang ) 대한간학회 2011 Clinical and Molecular Hepatology(대한간학회지) Vol.17 No.3

Background/Aims: JX-594 is an oncolytic virus derived from the Wyeth vaccinia strain that causes replication-dependent cytolysis and antitumor immunity. Starting with a cross-examination of clinical-trial samples from advanced hepatocellular carcinoma patients having high levels of aldosterone and virus amplification in JX-594 treatment, we investigated the association between virus amplification and aldosterone in human cancer cell lines. Methods: Cell proliferation was determined by a cell-counting-kit-based colorimetric assay, and vaccinia virus quantitation was performed by quantitative polymerase chain reaction (qPCR) and a viral plaque assay. Also, the intracellular pH was measured using a pH-sensitive dye. Results: Simultaneous treatment with JX-594 and aldosterone significantly increased viral replication in A2780, PC-3, and HepG2 cell lines, but not in U2OS cell lines. Furthermore, the aldosterone treatment time altered the JX-594 replication according to the cell line. The JX-594 replication peaked after 48 and 24 hours of treatment in PC-3 and HepG2 cells, respectively. qPCR showed that JX-594 entry across the plasma membrane was increased, however, the changes are not significant by the treatment. This was inhibited by treatment with spironolactone (an aldosterone-receptor inhibitor). JX-594 entry was significantly decreased by treatment with EIPA [5-(N-ethyl-N-isopropyl)amiloride; a Na+/H+-exchange inhibitor], but aldosterone significantly restored JX-594 entry even in the presence of EIPA. Intracellular alkalization was observed after aldosterone treatment but was acidified by EIPA treatment. Conclusions: Aldosterone stimulates JX-594 amplification via increased virus entry by affecting the H+ gradient. (Korean J Hepatol 2011;17:213-219)
