Background and Objectives : Cigarette smoking is a major factor and the most modifiable risk factor for atherosclerosis. Endothelial dysfunction is an early event in atherosclerosis, before the structural change of the systemic arteries. We hypothesized that endothelial dysfunction might be present in the systemic arteries of young adult smokers and that this might be dose-dependent phenomenon. Therefore, we try to certify that smoking is associated with endothelial dysfunction in healthy young adults without other risk factor of atherosclerosis. Subjects and Methods : we studied noninvasively 29 subjects aged 3 to 4 decades without other risk factor of atherosclerosis, they were composed of the two groups, current smokers(n=15) and nonsmokers(n=14). Smoking history varied from 3 to 20 pack years. Using high-resolution ultrasound, vessel diameter and mean flow rate were measured at rest, during reactive hyperemia(with flow-mediated endothelium-dependent dilation), and after sublingual nitroglycerin(NG-induced endothelium-independent vasodilation). Result : Flow mediated endothelium dependent dilation was observed in the control subjects (9.4±3.44%) but was impaired in the smokers(5.8±2.51%)(p=0.004). NG-induced endothelium independent dilation is no difference in all subjects. Conclusion : Cigarette smoking is associated with endothelial dysfunction in healthy young adults.

( Jeong Sook Kim ),( In Ok Lee ),( Kyung Jin Eoh ),( Young Shin Chung ),( Inha Lee ),( Jung-yun Lee ),( Eun Ji Nam ),( Sunghoon Kim ),( Young Tae Kim ),( Sang Wun Kim ) 대한산부인과학회 2017 Obstetrics & Gynecology Science Vol.60 No.2

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.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

Yan, Bing Chun,Park, Joon Ha,Kim, Sung Koo,Choi, Jung Hoon,Lee, Choong Hyun,Yoo, Ki-Yeon,Kwon, Young-Geun,Kim, Young-Myeong,Kim, Jong-Dai,Won, Moo-Ho Kluwer Academic/Plenum Publishers 2012 Cellular and molecular neurobiology Vol.32 No.8

<P>In the present study, we investigated neuronal death/damage in the gerbil hippocampal CA1 region (CA1) and compared changes in some trophic factors, such as brain-derived neurotrophic factor (BDNF), glial cell line-derived neurotrophic factor (GDNF) and vascular endothelial growth factor (VEGF), in the CA1 between the adult and young gerbils after 5 min of transient cerebral ischemia. Most of pyramidal neurons (89%) were damaged 4 days after ischemia-reperfusion (I-R) in the adult; however, in the young, about 59% of pyramidal neurons were damaged 7 days after I-R. The immunoreactivity and levels of BDNF and VEGF, not GDNF, in the CA1 of the normal young were lower than those in the normal adult. Four days after I-R in the adult group, the immunoreactivity and levels of BDNF and VEGF were distinctively decreased, and the immunoreactivity and level of GDNF were increased. However, in the young group, all of their immunoreactivities and levels were much higher than those in the normal young group. From 7 days after I-R, all the immunoreactivities and levels were apparently decreased compared to those of the normal adult and young. In brief, we confirmed our recent finding: more delayed and less neuronal death occurred in the young following I-R, and we newly found that the immunoreactivities of trophic factors, such as BDNF, GDNF, and VEGF, in the stratum pyramidale of the CA1 in the young gerbil were much higher than those in the adult gerbil 4 days after transient cerebral ischemia.</P>

저자들은 새로 개발된 alyllamine계 항진균제인 터비나핀의 발톱의 조갑백서에서 치료 효과, 내약성 및 부작용 등을 평가하기 위해 triazole계의 이트라코나졸과 이중 맹검으로 비교 조사하였다. 치료방법은 터비나핀은 250㎎/days로 12주간, 이트라코나졸은 100㎎/day로 124주간 복용하고 양군 모두 치료 시작 후 36주까지 추적 관찰하였다. 조사방법은 조갑진균증 환자에 대해 치료에 대해 설명후 동의서를 받고 장기간 치료가 부적합한 경우를 제외한 149명(터비나핀군 74명, 이트라코나졸군 75명)이 치료를 받았으며 이중 25명이 탈락하고 13명이 부작용등으로 치료를 중지하여 111명(터비나핀군 51명, 이트라코나볼군 60명)이 치료를 완료하였다. 1. 임상적인 소견은 점진적으로 호전되었으며, 치료 시작후 36주에는 병변조갑의 감소 비율로 볼때 터비나핀군은 51명중 완전치료가 24(47.0%), 76%이상 호전이 18명(35.3%), 51%~75% 호전이 6명(11.8%), 26~50% 호전이 2명 (3.9%), 25% 이하의 호전을 보인 예는 1명(2.0%)였다. 이트라코나졸군은 60명중 완전치료가 27(45.0%), 76% 이상 호전이 14명(23.3%), 51%~75%호전이 9명(15.0%), 26~50% 호전이 2명(3.9%), 25% 이하의 호전을 보인 예는 1명(2.0%)였다. 이트라코나졸군은 60명중 완전치료가 27(45.0%), 76% 이상 호전이 14명(23.3%), 51%~75%호전이 9명(15.0%), 26~50% 호전이 7명 (11.7%), 25% 이하의 호전을 보인예는 3(5%)였다. 2. KOH도말 검사에서 음성 소견을 보인 비율은 터비나핀은 24주 후 50예(98.0%)였으며, 36주후에는 모두 음성을 나타내었고, 이트라코나졸은 치료 24주 후 51예(85.0%)였고, 36주후에는 59예(98.3%)에서 음성을 나타내었다. 진균배양 검사에서는 치료 12주 후에 터비나핀군은 51예중 44예에서 (86.3%), 이트라코나졸군은 60예중 52예에서 각각 음성이었으며(86.7%), 치료 36주 후에는 양군 모두에서 음성이었다. 3. 내약성은 양군 모두 시간이 지나면서 증가하였으며, 터비나핀은 moderate이상이 98~·00%였고, 이트라코나졸은 moderate이상이 96.7~100%였다. 4. 부작용은 위장관 증상이 가장 많았고 터비나핀은 23명, 이트라코나졸은 37명이었고, 2명, 3명에서 각각 일시적인 간효소치의 상승이 있었다. 이상의 결과로 보아 조갑진균증의 치료에 터비나핀 1일 250㎎씩 12주간의 경구투여는 치료율, 안정성 및 부작용에서, 추천할 만한 치료법이라 생각된다. In this randomized double-blind trial on multicenter study, the efficacy of the new antifungal agent, terbinafine(Lamlsil) was compared with the triazole antifungal agent, itraconazole, in the treatment of patients with onychomychosis. One hundred and forty nine patients(74 terbinafine, 75 itraconazole) with onychomlychosis were enrolled. Twenty five patients were lost to follow up and 13 reported adverse reaction with premature discontinuation of therapy. And 111 patients were eligible for follow-up until 36 weeks after starting the treatment. Fifty one patients received Lamisil(terbinafine) 250mg daily for twelve weeks (terbinafine group) and 50 received itraconazole 100mg daily for 24 weeks (itraconazole group). They were checked clinical symptoms(onycholysis, subungual hyperkeratosis, paronychyal inflammation, color change, brittleness, ridging, normal length of nails) and mycological improvement with KOH wet mount and culture during the study. Clinical improvements were slow but progressive. In terbinafine group of 5t patients, 24 patients(47.0%) were completely cleared and 18 patients(35.3%) were improved more than 76%, and 6 patients(11.8%) were improved in 53-75%. In itraconazole group of 60 patients, 27 patients(45.0% ) were completely cleared and 14 patients(23-3%) were improved more than 76%, and 9 patients(150%) were improved in 51-75% . In mycologic study, cure rate of the terbinafine group showed all negative at 36 week after the treatment while ittraconazole group showed all negative in culture but negative KOH in 98.3%. Adverse reactions and tolerability of both the drugs were good and net different significantly. All these findings suggest that the efficacy of Lamisil(terbinafine) 250mg daily for 12 weeks in the treatment of onychomycosis was similar to that of itraconazole 100mg daily for 24 weeks.

To shorten the processes of MMC fabrication, a number of techniques are being studied. In this study, a new process for MMC's fabrication was developed utilizing vacuum hot pressing and subsequent extrusion. MMC's with pure Al and 2024Al matrices reinforced with various volume fractions of SiC particulates were produced at 400℃ by vacuum hot pressing(VHP), followed by direct extrusion with extrusion ratios of 10:1 at 480℃ at constant ram speed of 2㎜/sec. The effects of extrusion pressure and relative density according to the volume fractions of the reinforcement were compared with the resultant metallurgical microstructures. Young's moduli of the manufactured composites were measured by the sonic resonance method, damping capacity by free decay method. Measured Young's moduli of the composites at room temperature were compared with the predictions based on Rule of Mixtures, Halpin-Tsai and Mean-field models. Measured Young's moduli of the composites are in good agreement with the predictions based on Mean-field model. The composites reinforced with finer particles showed higher damping capacity under the same amount of SiC reinforcement.

An instrument for measuring cone penetration using the strain gage system was devised. The soil hardness of given soils under different conditions can be measured and compared by using this instrument. The soil hardness is a very useful index for making decisions in various aspects of the field and laboratory use; the workability of the agricultural machinery on the given field, and the uniformity of soil hardness of the stuffed soil in the soil bin which is tilled repeatedly. The performance of this newly devised cone penetrometer was compared with the conventional one through the field test. The summarized results are as follows; 1. In case of KM-1 type cone penetrometer, the newly devised one, the relation between the cone index and the strain indicated are as follows, Ci=0.026642ε₁-0.4173 when base area is 3.23㎠ Ci=0.013342ε₂ when base area is 6.45㎠ 2. The KM-1 type cone penetrometer is more convenient than conventional one in view of its accuracy and its adaptability of the self recording system. 3. Cone index increases gradually as penetrating depth into the soil is increased. Its maximum value appeared at the depth of about 20cm and then the cone index decreases until the cone reaches the depth of 40cm. It is assumed that such increase of cone index is caused by the existence of plow pan in paddy fields. 4. When cone penetrometers are manually penetrated into the soil deeper than 20cm from ground surface, its found to be difficult to carry out measuring operations due to high soil resistance to penetration. So, in order to use cone penetrometers below the depth more than 20cm, some equipment is necessary to maintain uniform penetrating speed of the cone. 5. Under the same soil conditions, the relation between Cik and Cic, cone indexes derived KM-1 type from conventional cone penetrometers respectively, was as follow;??

In mandibular tumor treatment case,mandibulectomy is frequently performed.This mandibulectomy may result in facial changes, esthetic and phonetic problems, reduced mastication and swallowing functions. When we treat this patients, using primary reconstruction with autogenous bine graft or secondary reconstruction with delayed bone graft after applied bridge plate removal. After bone graft is done, prosthodontic treatment is essential for the rehabilitation of facial esthetics, phonetics and mastications. But, tissue-supported prostheses have the problems of frequent breakdown of underlying bone anf soft tissue, increasing risk of intraoral infection, mobility of prostheses, unsatisfactory function, problems in esthetics, poor patient co-operation. Now, osseointegrated implants are used as the main treatment of fully or partially edentulois state of mandible, long term clinical data are satisfactory, too. So, we may choose the implant,as the useful prosthodontic treatment method of mandibular reconstruction using autogenous bone graft. Regardless of this harmful situation, as astivity(in malignant madibular tumor), and relatively poor condition of grafted bone, thoughtful treatment plan, delicate and technique, persistent follow-ups make much more satisfactory results than those of removable prostheses. So. we reported a good results in the case of implat-retained protheses after mandibulectomy and autogenous bone graft.
