Objective This study aimed to introduce a method to remove huge ovarian tumors (≥15 cm) intact with single-port laparoscopic surgery (SPLS) using SW Kim`s technique and to compare the surgical outcomes with those of laparotomy. Methods Medical records were retrospectively reviewed for patients who underwent either SPLS (n=21) with SW Kim`s technique using a specially designed 30×30-cm2-sized 3XL LapBag or laparotomy (n=22) for a huge ovarian tumor from December 2008 to May 2016. Perioperative surgical outcomes were compared. Results In 19/21 (90.5%) patients, SPLS was successfully performed without any tumor spillage or conversion to multi-port laparoscopy or laparotomy. There was no significant difference in patient characteristics, including tumor diameter and total operation time, between both groups. The postoperative hospital stay was significantly shorter for the SPLS group than for the laparotomy group (median, 2 [1 to 5] vs. 4 [3 to 17] days; P<0.001). The number of postoperative general diet build-up days was also significantly shorter for the SPLS group (median, 1 [1 to 4] vs. 3 [2 to 16] days; P<0.001). Immediate post-operative pain score was lower in the SPLS group (median, 2.0 [0 to 8] vs. 4.0 [0 to 8]; P=0.045). Patient-controlled anesthesia was used less in the SPLS group (61.9% vs. 100%). Conclusion SPLS was successful in removing most large ovarian tumors without rupture and showed quicker recovery and less immediate post-operative pain in comparison to laparotomy. SPLS using SW Kim`s technique could be a feasible solution to removing huge ovarian tumors.

<▼1><P><B>Significance</B></P><P>Leaf senescence is regulated in a complex manner, involving time-dependent interactions with developmental and environmental signals. Genetic screens have identified key regulators of senescence, particularly late-stage senescence regulators. Recently, time-course gene-expression and network analyses, mostly analyses of static networks, have predicted many senescence regulators. However, senescence is defined by time-evolving networks, involving the temporal transition of interactions among senescence regulators. Here, we present time-evolving networks of NAM/ATAF/CUC (NAC) transcription factors, central regulators of leaf senescence in <I>Arabidopsis</I>, via time-course gene-expression analysis of NACs in their mutants. These time-evolving networks revealed a unique regulatory module of NACs that controls the timely induction of senescence-promoting processes at a presenescent stage of leaf aging.</P></▼1><▼2><P>Senescence is controlled by time-evolving networks that describe the temporal transition of interactions among senescence regulators. Here, we present time-evolving networks for NAM/ATAF/CUC (NAC) transcription factors in <I>Arabidopsis</I> during leaf aging. The most evident characteristic of these time-dependent networks was a shift from positive to negative regulation among NACs at a presenescent stage. ANAC017, ANAC082, and ANAC090, referred to as a “NAC troika,” govern the positive-to-negative regulatory shift. Knockout of the NAC troika accelerated senescence and the induction of other <I>NAC</I>s, whereas overexpression of the NAC troika had the opposite effects. Transcriptome and molecular analyses revealed shared suppression of senescence-promoting processes by the NAC troika, including salicylic acid (SA) and reactive oxygen species (ROS) responses, but with predominant regulation of SA and ROS responses by ANAC090 and ANAC017, respectively. Our time-evolving networks provide a unique regulatory module of presenescent repressors that direct the timely induction of senescence-promoting processes at the presenescent stage of leaf aging.</P></▼2>

Identification of a sensitive urinary biomarker, selenium-binding protein 1, for early detection of acute kidney injury

Kim, Kyeong Seok,Yang, Hun Yong,Song, Hosup,Kang, Ye Rim,Kwon, JiHoon,An, JiHye,Son, Ji Yeon,Kwack, Seung Jun,Kim, Young-Mi,Bae, Ok-Nam,Ahn, Mee-Young,Lee, Jaewon,Yoon, Sungpil,Lee, Byung μ,Kim, Hyung TAYLOR & FRANCIS 2017 Journal of Toxicology and Environmental Health Vol.80 No.9

<P>Acute kidney injury (AKI) is associated with increased mortality rate in patients but clinically available biomarkers for disease detection are currently not available. Recently, a new biomarker, selenium-binding protein 1 (SBP1), was identified for detection of nephrotoxicity using proteomic analysis. The aim of this study was to assess the sensitivity of urinary SBP1 levels as an early detection of AKI using animal models such as cisplatin or ischemia/reperfusion (I/R). Sprague-Dawley rats were injected with cisplatin (6 mg/kg, once i.p.) and sacrificed at 1, 3, or 5 days after treatment. Ischemia was achieved by bilaterally occluding both kidneys with a microvascular clamp for 45 min and verified visually by a change in tissue color. After post-reperfusion, urine samples were collected at 9, 24, and 48 hr intervals. Urinary excretion of protein-based biomarkers was measured by Western blot analysis. In cisplatin-treated rats, mild histopathologic alterations were noted at day 1 which became severe at day 3. Blood urea nitrogen (BUN) and serum creatinine (SCr) levels were significantly increased at day 3. Levels of urinary excretion of SBP1, neutrophil gelatinase-associated lipocalin (NGAL), and a tissue inhibitor of metalloproteinase-1 (TIMP-1) were markedly elevated at day 3 and 5 following drug treatment. In the vehicle-treated I/R group, serum levels of BUN and SCr and AST activity were significantly increased compared to sham. Urinary excretion of SBP1 and NGAL rose markedly following I/R. The urinary levels of SBP1, NGAL, TIMP-1, and KIM-1 proteins excreted by AKI patients and normal subjects were compared. Among these proteins, a marked rise in SBP1 was observed in urine of patients with AKI compared to normal subjects. Based upon receiver-operator curves (ROC), SBP1 displayed a higher area under the curve (AUC) scores than levels of SCr, BUN, total protein, and glucose. In particular, SBP1 protein was readily detected in small amounts of urine without purification. Data thus indicate that urinary excretion of SBP1 may be useful as a reliable biomarker for early diagnosis of AKI in patients.</P>

보완대체의학에 대한 간호학과 학생의 주관성 연구

보완대체의학은 건강증진과 질병예방을 위한 총체적인 접근법의 하나로 환자뿐 아니라 일반인들 사이에서도 이용률이 증가하고 있고, 교육에 있어서도 보완대체요법 관련 교과목을 의학이나 간호학의 정규 교과과정 내에 포함시키는 대학이 늘어남에 따라 미래의 건강관리 제공자인 간호학생들의 보완대체의학에 대한 인식이나 태도를 파악하는 것은 중요하다. 이에 본 연구는 Q방법론을 이용하여 보완대체의학에 대한 간호학생의 반응을 유형화하고 구체적인 특성을 파악하고자 시도되었다. 보완대체의학에 대한 간호학생의 반응은 4개로 유형화되었으며, 각 유형은 실용적 확신형, 견제형, 가치 인정형, 제한적 수용형으로 명명하였다. 각 유형의 명명에서 볼 수 있듯이 간호학생들은 인식에서 약간씩은 차이가 있지만 보완대 체의학에 대해 비교적 긍정적인 태도를 갖고 있는 것으로 나타났다. 이러한 결과는 간호학생들이 보완대체요법에 대해 긍정적인 태도를 보였음을 보고한 Kim (2004), Kim, Erlen, Kim 과 Sok (2006), Uzun과 Tan (2004)의 연구결과와 일치한다고 할 수 있다. 제1유형은 ‘실용적 확신형’으로 보완대체요법의 효과를 단순히 인정하기보다는 실용성에 초점을 맞춘 유형이다. 보완대체요법의 문제점으로 많이 지적되는 것 중의 하나가 사람마다 효과가 다르기 때문에 일률적으로 적용하기 어렵다는 것인데, 제1유형의 대상자들은 이를 오히려 실용적인 측면으로 인식하여, 보완대체요법의 효과는 사람마다 결과가 다르게 나타날 수 있기 때문에 어떤 치료법을 일률적으로 적용하기보다는 자신한테 맞는 보완대체요법을 찾아야 한다고 인식하는 것이다. 또한 제1유형의 대상자들은 보완대체요법에 대해 효과가 없거나 의미 없는 행위이며 의학적 치료를 방해하거나 효과를 믿을 수 없다는 데는 강하게 반대를 했다. 간호학생의 보완요법에 대한 태도를 조사한 Kim (2004)의 연구에서도 보완대체요법이 엉터리 치료법이라는 데에 대해 가장 부정적인 태도를 보임으로써 본 연구결과와 일치한다. 간호학생의 주관성을 조사한 Hwang (2004)의 연구에서는 간호학생의 인식이 세 가지로 유형화되었는데 ‘긍정적 인정형’으로 명명된 사람들은 보완대체요법이 건강의 유지와 증진에 도움이 되며, 면역력을 향상시키고 심리적 지지를 제공하고 몸을 보호하며 안위를 증진시키는 것으로 인식하고, 엉터리 치료법이고 환자의 치유에 방해가 되므로 사용을 피해야 하고 과학적인 근거를 설명할 수 없으므로 신뢰할 수 없다는 데대해서는 강한 반대의 의사를 표함으로써 본 연구에서 ‘실용적 확신형’으로 명명된 대상자들과 유사한 인식양상을 보였다. 본 연구에서의 ‘실용적 확신형’의 사람은 보완대체요법에 대해 쉽게 접근할 수 있고 여러 가지 효과를 한꺼번에 기대할 수 있다는 점에서 좀 더실용적인 면을 강조한 점이 차이라고 할 수 있다. 제2유형은 ‘견제형’으로 보완대체의학의 부작용에 대한 염려와 효과에 대한 정확한 작용기전의 뒷받침을 요구하는 유형으로, Hwang (2004)의 연구에서 보완대체요법은 체계적인 검증 후에 정통적인 치료와 병행해서 사용해야 효과가 있다고 하여 ‘객관적 수용형’으로 명명한 것과 매우 유사하다. 또한 간호사를 대상으로 한Son (2002)의 연구에서 보완대체요법을 현대의학을 보완해주는 치료법으로 고려하면서 과학적인 근거를 확립하는 일이 필요하다고 제시한 것과 일치한다. Ernst (2000)도 보완대체요법을 이용하는 대상자들은 보완대체요법의 안전성과 효율성에 대해서 알고자 하며, 보완대체요법에 대해 건강관리자와 개방적으로 의사소통할 때 안정성이 확립된다고 하여 본 연구의 ‘견제형’ 유형과 유사한 것을 볼 수 있다. ‘견제형’의 사람들은 보완대체요법에 대한 효과가 사람마다 다르게 나타나므로 보완대체요법을 무조건적으로 받아들이기 이전에 임상적인 효율성에 대한 정확한 근거와 과학적인 검증에 관한 많은 연구들이 이루어져야 할 것을 강조한 유형이다. 이러한 견해는 최근 의학이나 간호학 교육에서 근거중심의 행위를 강조하고 있는 것을 반영하는 것이라 할 수 있다. 제3유형은 ‘가치 인정형’으로 보완대체의학에 대해 과학적 신뢰를 갖고 있지는 않지만 보완대체요법의 건강증진에 대한 가치를 인정하는 유형이다. 의사를 대상으로 보완대체요법의 치료 효과에 대한 태도를 분석한 Jang 과 Park (2003)의 연구에서 62.2%는 ‘설명하기는 어렵지만 보완대체요법은 효과가 있다’고 하여 작용기전에 대한 이론적 근거는 부족하지만 치료효과에 대해서는 비교적 긍정적으로 인식하고 있는 것으로 나타나 본 연구 대상자의 ‘가치 인정형’과유사한 태도를 보였다. 또한 초등학교 보건교사를 대상으로 보완대체요법의 문제점에 대한 인식을 조사한 Kim, Kim과 Cho (2007)의 연구에서 40.5%가 ‘과학적인 검증의 부족으로 치료효과가 의심된다’고 지적하였지만 학교보건실무에서 보완대체요법의 적용가능성에 대한 질문에는 72.1%가 ‘가능하다’고 하였으며, 78%가 보완대체요법의 적용이유로 ‘증상완화, 치료보조의 효과’ 때문이라고 답하여 본 연구결과와 유사한 인식을 보였다. 또한 보완대체요법 교과목을 수강한 간호학생들에게 보완대체요법의 치료적 효과에 대해조사한 Kim (2005)의 연구에서도 ‘건강유지증진을 위해 일반 대중들도 보완대체요법을 많이 적용하고 있다’에 대해 5점 만점에 3.7점으로 응답하여 비교적 긍정적 태도를 보였다. 위의 결과들을 종합해 볼 때 보완대체요법이 체계적인 지식체로 인정하기엔 과학적 근거가 부족하지만 신체의 자연 치유력과 면역력을 증가시켜 건강증진에 영향을 미친다는 본 연구의 ‘가치 인정형’과 유사하다고 할 수있다. 제4유형은 ‘제한적 수용형’으로 보완대체의학이 건강증진에 도움이 되고 심리적 안정감을 주는 여러 가지 효과가 있는 반면 부작용이 있을 수 있고 사람마다 효과가 다르게 나타날 수 있으므로 작용기전에 대한 연구도 더 필요하다고 생각하는 유형으로 무조건적으로 수용하기보다는 제한적으로 수용하는 유형이다. 대학생을 대상으로 보완대체요법의 문제점에 대한 인식을 조사한 Gwon 등(2008)의 연구에서 ‘부작용을 예측할 수 없다’가 37.7%로 가장 높았고, 23.2%가 ‘비과학적이다’라고 응답함으로써 자신에게 맞는 보완대체요법을 찾아 효과를 볼 수는 있지만 부작용에 대한 우려, 효과에 대한 객관성 부족 및 작용기전에 대한 체계적 검증의 필요성을 언급한 본 연구에서의 ‘제한적 수용형’ 대상자와 유사한 인식을 보였다. Purpose: The purpose of this study was to grasp the subjectivity of the nursing students toward CAM and put the outcomes into use as basic facts and figures in developing and applying a curriculum associated with CAM. Methods: Q methodology was employed to explore the nursing students` subjectivity from their rank-order statements. For the Q population, individual in-depth interviews and literature research were conducted. Finally, 30 participants completed 40 Q statements. The data were analyzed using the QUANL software package. Results: The current survey that probed into the subjectivity of the nursing students relative to CAM abstracted four categories, namely, practical and convinced type, keep-under-control/wait-and-see type, merit acknowledging type and limitedly accepting type. Conclusion: It is recommended that various educational programs should be developed to shift the awareness of CAM on the part of the nursing students, based on the findings set forth in the current study.

김옥남,김은정 숙명여자대학교 약학연구소 1993 약학논문집-숙명여자대학교 Vol.9 No.-

The pharmacokinetics were compared after peritoneal administration of one of the new platinum species, PtCl₄(2-CEen) and cisplatin, 5mg/kg, respectively, to rabbits by measuring the total platinum concentrations flameless atomic absorption spectrometrically. Following intraperitoneal(i.p.) injection of PtCl₄(2-CEen), platinum levels reached maximum concentration of 1.6㎕/㎖ at 12 hours and then decreased slowly to 0.48㎕/㎖ at 5th day. After i.p. administration, plasma concentrations of both total platinum of PtCl₄ (2-CEen) and cisplatin decayed biphasically. The rabbits treated with PtCl₄(2-CEen) survived 5 days which is longer than 2 days treated with cisplatin. However, there was no significant differences of pharmacokinetic parameters between two treatments.

The purpose of this study was to verify the effect of Text Reading Skills Training program on academic achievement and study habits. The subjects were 80 seventh-grade male students. They were randomly assigned to one of two groups. Half of the subjects (experimental group) were trained with Text Reading Training program, and the other half (control group) received no training. After and before the training, the subjects of two groups were administered the study Habit Inventory and then academic achievenment scores were obtained. Training procedure was divided into five periods; (1) (1) Reading Skills, (2) Reading Skills Training, (3) Text Readng, Skills, (4) Text Reading Skills Training(I) and (5) Text Reading Skills Training(Ⅱ). A 2×2 analysis of variance was carried out to test statistical significance of the main and interaction effects of Study Habit scores. There is to significant main effect but significant interaction effect. So post-hoc test was conducted to test the difference of two mean scores of experimental and control group. And t-test was conducted to test statistical significance of mean difference in academic achievement scores between the two groups. Based upon the findings of the present study, the following conclusions were made; (1) There is a singnificant difference in reading habits and technique factors scores between experimental and control group. (2) There is no significant difference, but a little enhancement in motivation factors and total study Habit scores for experimental group's subjects, (3) There is no significant difference, but quiet a little enhancement in the mean scores of total academic achievenlent for the experimental groups subjects. But there is a significant difference in the mean scores of social subjects among the academic achievement. (4) It is clarified that the Text Reading Skills Training program which was used in this study is more effective in social subjects than others ; it seems that the development and appliance of the Text Reading Skills Training program should include the comprehensive and flexible content of the training, considering the trait of each subject and individual student.

The purpose of developing this program is to help the college students enhance not only reading skills and habits but also study skills, habits and attitudes, furthermore academic achievement through reading skills training. But the reading or text reading skills which have been introduced until now almost dealt with Robinson's SQ3R as a subskill of the whole study skills for only one or two sessions. So, we are intended to develop a series of study skills training program, which trains students in only one subskill intensively for ten or more sessions. This study skills training program I is just what I have explained, and deals with reading skills. It was made up of 3 parts. Part 1 is about General Reading Skills, which consist of the purposive reading, rapid reading, comprehensive reading, vocabulary enhancement, and reading et cetera. Part 2 is about Text Reading Skills, which consist of Survey, Exploring Key Words, Imagination, Reciting, and Repeating (SKIRR).And part 3 is skills which apply text reading skills to learning stages, which are preview, teaching, and review. And also, it is devided into 3 packages to use seperately, and each package consists of 3 parts which were introduced above. Package 1 is the student's guide, which contains the instruction about the reading skills. Package 2 is the instructor's manual, which is the instruction and question to train the reading skills. And Package 3 is the student's workbook, which consist of test, questions, and practice to train the reading skills.
