중력분을 이용하여 제면한 후 가압가열, microwave 및 가압가열과 microwave 병행 처리한 후, 생면 및 삶은 면의 품질에 미치는 영향에 대하여 알아보았다. 생면의 pH는 microwave 1 min 처리구에서 무처리구와 유의적인 차이를 보이지 않았으며, 수분 함량은 autoclave 50 min 처리구에서 무처리구와 유의적인 차이를 보이지 않았고, 그 외의 처리구에서는 모두 수분 함량이 감소함을 확인하였다. 면의 색도 측정 결과는 명도는 무처리구에 비해 모든 처리구에서 감소하였으며, 적색도는 microwave 1 min 처리구는 감소한 반면, 나머지 처리구는 증가하였다. 황색도는 autoclave 50 min 처리구와 autoclave 50 min/microwave 1 min 병행 처리구에서 증가한 반면, 나머지 물리적 처리구에서는 감소하였다. 삶은 면의 색도에서는 명도, 적색도, 황색도 모두에서 무처리구에 비하여 물리적 처리구에서 증가한 값을 나타내었다. 물성 측정 결과는 경도, 부착성, 응집성, 검성, 복원성에서 무처리구와 비교시 microwave 1 min 처리구는 유의적으로 감소하였으며, 그 외 처리구에서는 유의적으로 증가한 값을 나타내었다. 탄력성과 전단력은 모든 처리구에서 유의적으로 증가하였으며, 인장력은 가압가열 30 min 처리구와 무처리구가 유의적인 차이를 보이지 않았으나, 나머지 물리적 처리구에서는 유의적으로 증가하였다. 관능 평가 결과는 생면의 경우 색 항목에서 물리적 처리구들이 유의적으로 낮은 점수를 받았다. 맛, 질감, 향 항목에서는 무처리구와 물리적 처리구간 유의적 차이를 보이지 않았다. 전체적인 기호도에서는 microwave 1 min 처리구가 가장 높은 점수를 얻었으며, 가압가열(50 min)과 microwave(1 min) 병행 처리구는 무처리구와 비슷한 점수를 얻었다. 따라서 제면 후 가압가열 및 microwave 처리가 생면 및 삶은 면에 있어서 색과 질감 항목을 보완, 개선시킨다면 알러겐성이 저감화된 면을 제품화하는데 적합할 것으로 사료되어진다. This study was conducted to determine the effects of physical treatments for quality of wet noodles. Noodles were being tried with a microwave (for 1 min), an autoclave (for 30 or 50 min), and both autoclave and microwave (for 30/1 min or 50/1 min). The results showed that the pH levels were slightly decreased after treatments of autoclave and autoclave/microwave. The moisture contents were considerably decreased as compared to the control except autoclave (50 min). After all treatments, the lightness was decreased in all samples, but, redness was increased (except microwave) and the yellowness was increased after autoclave (50 min) and autoclave/microwave (50/1 min). Texture was increased as compared to the control except microwave. In the sensory evaluation, the noodles treated with microwave, autoclave (50 min), and autoclave/ microwave (50/1 min) showed a high score in overall preference. From these results, both the autoclave and microwave methods can be applied to the wet noodles without diminishing its quality to a great extent.

박원민(Won-Min Pak),김꽃봉우리(Koth-Bong-Woo-Ri Kim),김민지(Min-Ji Kim),박지혜(Ji-Hye Park),배난영(Nan-Young Bae),박선희(Sun-Hee Park),안동현(Dong-Hyun Ahn) 한국식품영양과학회 2016 한국식품영양과학회지 Vol.45 No.3

Histamine을 생성하는 Morganella morganii와 Photobacterium phosphoreum으로부터 crude histidine decarboxylase(HDC)를 추출하여 65~121°C로 열처리한 다음 균의 생육 및 효소 활성 변화에 대해 살펴보았다. 그 결과 M. morganii와 P. phosphoreum은 모든 열처리 조건에서 비 가열 처리구와 비교 시 균의 생육이 저해됨을 확인하였다. M. morganii와 P. phosphoreum 유래 HDC의 효소 활성은 65°C에서 90% 이상의 효소 활성이 저해됨을 확인하였고, 온도가 증가함에 따라 유의적으로 활성이 억제되는 것으로 나타났다. SDS-PAGE 결과에서는 65~100°C 범위에서 비가열 처리구와 비교 시 조효소액의 단백질 패턴의 변화가 크지 않았으나, 121°C에서 단백질 band의 강도가 크게 약해졌다. Native-PAGE에서는 65°C 처리 조건에서부터 단백질 패턴의 변화가 크게 나타났다. 따라서 가열처리(65~121°C)는 histamine 생성균인 M. morganii와 P. phosphoreum의 생육을 억제할 뿐만 아니라 HDC의 효소 활성도가 저해됨을 확인하여, 식품산업에서 적용되고 있는 열처리 조건에서 histamine 생성 억제에 큰 효과가 있는 것으로 생각한다. This study was performed to investigate the effects of various thermal treatments on the growth of Morganella morganii and Photobacterium phosphoreum and activity of crude histidine decarboxylase (HDC) obtained from M. morganii and P. phosphoreum. Crude HDC and the two strains were treated at 65°C/30 min, 80°C/10 min, 100°C/10 min, and 121°C/10 min. Activity of crude HDC decreased with increasing temperature. Viable cells counts of M. morganii and P. phosphoreum were not detected in any heated samples. SDS-PAGE patterns of heated HDC did not show significant differences up to 100°C. However, at 121°C, protein band intensity was weakened. In native-PAGE, there was a major change in the pattern of HDC at 65°C. These results suggest that thermal treatment can help to reduce histamine production by reducing HDC activity and growth of M. morganii and P. phosphoreum.

Objectives: Recently, [methyl-(11)^C]-(β-Hydroxyethyl)trimethylammonium ([(11)^C]choline) has been discovered to be a very effective tracer in imaging various human tumors using positron emission tomography. Because of the short half-life of C-11, it is very difficult to use in a routine imaging procedure and needs a frequent synthesis of [(11)^]choline. This can be supplemented by the substitution of [(11)^Ccholine with [methyS-18]fluorocholine. Here, we would like to report cell uptake and biodistribution of [(11)^Ccholine and [(18)^F]fluorocholine as a basic study. Methods [(11)^C]Choline was prepared by the treatment of [(11)^C]CHzI with N,N-dimethylaminoethanol and [18F]fluorocholine was synthesized from reaction of CHzBr[18F]F with N,N-dimethylaminoethanol. The radiochemical purity was checked by high performance liquid chromatography (HPLC). The biodistribution of [(11)^C]choline and [(18)^F]fluorocholine was determined in balb/c mouse at 5 min, 20 min, 40 min and 80 min. The cell uptake wa measured using glioma (9L) and colon adeocarcinoma (SW620). Results: The radiochemical purity was more than 98% after purification. In the liver, uptake did not change over time the uptake was 20/ID/g for [C]choline and 13%ID/g for [(18)^F]fluorocholine. In the kidney, radioactivity decreased over tirne the uptake was 15%1D/g for [(11)^Ccholine and 20%ID/g for [(18)^F]fluorocholine, 80 min post-injection. The cell uptake of [(11)^Ccholine was 4.93% for glioma (9L) and 18.69F for colon adenocarcinoma (SW620). For [(18)^F]fluorocholine, 1.77% for glioma (9L) and 2.77% for colon adenocarcinoma (SW620). Conclusion: [(11)^CCholine and [(18)^F]fluorocholine showed a different cell uptake tendency, depending on cancer cell line. (Korean J Nucl Med 200135:185-191)

본 연구에서는 가압가열 및 microwave 처리가 gliadin의 항원성에 미치는 영향을 살펴보기 위해 강력분에 가압가열과 microwave를 단독 또는 병행으로 처리하여 Ci-ELISA, SDS-PAGE 및 immunoblotting을 실시하였다. 가압가열 처리의 경우 시간이 길어질수록 IgG와의 결합력이 감소하였으며, 특히 50분 처리구에서 약 87%로 가장 낮은 결합력을 보였다. 또한 SDS-PAGE와 immunoblotting 결과에서도 무처리구에서 강하게 보였던 gliadin band가 가압가열처리에 의해 거의 소실되고 항체와 반응하지 않았다. 가압가열 및 microwave를 병행 처리 시도 마찬가지로 gliadin의 결합력이 감소하였으며, 처리구 중 가압가열 50분, microwave 5분 처리구에서 약 93%로 가장 낮은 결합력을 보였다. 반면 microwave를 단독으로 처리한 경우에는 일부 단백질의 변화는 관찰되었으나, 항원성 감소에는 효과가 없음을 확인하여 단백질 변화가 항원성에는 큰 효과를 준 것 같지 않다. 이상의 결과를 통해 가압가열 단독 처리 및 가압가열 및 microwave의 병행처리 시 gliadin의 항원성이 감소함을 확인하였다. This study was conducted to evaluate the effects of physical treatments on the antigenicity of gliadin in strong wheat flour. Strong wheat flour was treated with an autoclave (5, 10, 30, 50 min), a microwave (1, 5, 10 min), or both (10, 30, 50 min/ 5, 10 min), followed by SDS-PAGE, immunoblotting, and Ci-ELISA using anti-gliadin IgG. The results indicated that the binding ability of IgG to gliadin in strong wheat flour slightly decreased after autoclaving or autoclaving/microwaving. In particular, the binding ability was reduced to about 87% after autoclaving for 50 min and to 89% after autoclaving/microwaving (50/5 min). In addition, gliadin bands in the 50 min autoclaved group disappeared in both SDS-PAGE and immunoblotting. On the other hand, the antigenicity of gliadin was unaffected by microwaving alone. In conclusion, the results of this study suggest that autoclaving may reduce the antigenicity of gliadin in strong wheat flour.

안용민,강대엽,권준수,김창윤,김철응,반건호,신영민,이기철,이동우,이중서,조현상,채정호,김용식 大韓神經精神醫學會 2001 신경정신의학 Vol.40 No.4

연구목적 : 본 다기관 공동임상연구는 국내 환자를 대상으로 새로운 항정신병약물인 올라자핀의 치료 효과와 안전성을 확인하고자 시행되었다. 방 법 : 1999년 7월부터 2000년 3월까지 국내 10개 병원에 방문한 정신분열병 및 정신분열형 장애 105명을 대상으로 비대조 개방 임상연구를 시행하였다. 중등도 이상의 정신병 증상을 지니거나, 부작용으로 약물교체가 필요한 경우 또는 기분장애 증상의 치료가 필요한 환자를 대상으로 하였다. 2∼7일간의 약물 배설기간 후에 1일 10mg의 올란자핀을 투여하였고, 이후로 3∼7일 간격으로 용량을 조절하여 총 8주간 투여하였다. 치료 효과는 PANSS(Positive and Negative Syndrome Scale), BPRS(Brief Psychiatric Rating Scale), CGI(Clinical Global Impression-Severity), MADRS(Montgomery-Asberg Depression Rating Scale), HAM-A(Hamilton Rating Scale for Anxiety)로 판정하였다. 안전성 평가는 자발적인 이상반응 보고, 활력징후와 혈액 검사 및 SAS(Simpson-Angus Scale), BARS(Barnes Akathisia Rating Scale), AIMS(Abnormal Involuntary Movement Scale)척도를 이용하였다. 결 과 : 105명중에서 85.7%인 90명이 8주간의 치료를 완료하였다. 평균 최빈 용량은 일일 16.1(±4.7)mg이었고, 종료시점에서의 BPRS전체 점수가 기저 상태에 비해 40%이상 감소된 반응군은 69.5%이었다. PANSS의 양성 증후군과 일반정신병리 뿐만 아니라 음성 증후군 소척도에서도 유의한 감소를 보였으며, 이 감소들은 치료 초기부터 나타나서 8주간 지속되었다. 43.8%의 피험자가 중등도 이상의 우울증상을 같이 지니고 있었으며, 올란자핀에 의해 MADRS와 HAM-A가 유의하게 감소하였다. 치료 기간 동안에 활력징후에는 뚜렷한 변화가 없었으나 체중은 8주간 지속적으로 증가하였다. SAS와 AIMS는 감소하였으며, 정좌불능증을 제외한 나머지 추체외로 증상의 발생비율도 낮았다. 임상적인 증상이나 징후를 동반하지 않는 ALT/SGPT의 상승을 보였지만 프로락틴을 포함하는 대부분의 혈액 검사상 뚜렷한 이상 변화는 없었다. 결 론 ; 비록 본 임상연구가 비대조 개방 임상연구로서 많은 제한점을 가지고 있지만, 올란자핀이 기존 약물에 내약성을 보이거나 기분증상을 동반하는 정신병에 치료 효과가 있었다. 그리고 기존 항정신병약물 치료시에 문제가 되었던 추체외로 증상과 고프르로락틴 혈증을 포함하는 대부분의 부작용면에서 안전성을 보여 주었다. Objective : This multicenter clinical trial was carried out to investigate the efficacy and the safety of olanzpine for the treatment of Korean patients. Mothod : 105 patients with schizophrenia and schizophreniform disorder, visited at 10 mental or university hospitals, had received an open and non-comparative treatment with olanzapine for 8 weeks. Patients had psychotic or depressive symptoms with the severity above moderate degree or intolerable side effects to previous antipsychotics. After a wash-out period of 2-7 days, 10mg olanzapine was prescribed initially to all the patients, and then the dosage could be adjusted within the range of 5-20mg/day of olanzapine by 3-7 days. Results : 90(85.7%) of 105 patients completed the 8-weeks trial and the mean modal dose of olanzapine was 16.1(±4.7%)mg/day. At the end of the trial, 73 patients(69.5%) were classified as responder, which was defined as 40% or more improvement in BPRS(Brief Psychiatric Rating Scale) score comparing to baseline. There was a significant reduction in the scores of PANSS(Positive and Negative Syndrome Scale)and subscales including negative symptom scores and CGI. Also weekly analysis showed that the reductions in scores were kept on for the whole period of the trial. 43.8% of all the patients had depressive symptoms at the baseline and total scores of MADRS(Montgomery-Asberg Depression Rating Scale) and HAM-A(Hamilton Rating Scale for Anxiety) were also reduced after the trials. Vital signs revealed no clinically significant changes but continuous weight gain was observed during the treatment with olanzapine. The scores of SAS(Simpson-Angus Scale) and AIMS(Abnormal Involuntary Movement Scale) for assessing the EPS(extrapyramidal symptoms)and tardive dyskinesia respectively were significantly decreased and only a few patients reported EPS as adverse events. Although mild and clinically non-significant of ALT/SGPT was observed, most laboratory parameters including plasma prolactin level showed to significant changes during the trial. Conclusions : Although this trial had many limitations because it was a non-comparative and open study, olanzapine showed high efficacy on the positive, negative and depressive symptoms in schizophrenia and schizophreniform disorder.In addition to that, olanzapine showed a substantially favorable safety profile, such as low incidence of EPS and hyperprolactinemia.

男性不育에 關한 文獻的 考察

安世永,曺東鉉,杜鎬京,朴民豪 慶熙大學校韓醫科大學韓醫學硏究所 1995 慶熙韓醫大論文集 Vol.18 No.2

I could get to the conclusions as follows after studying our professors Drs' books and current magazine on Male Infertility. 1. Most of Drs. considered the reason of male infertility as Weakness(虛勞), which specially meant Jung(精)(the essence of life, or in this case could be semen) scarcity, Jung coldness, Jung lackness. They attributed the infertility to the seminal disorder. 2. In the treatment for male infertility, they emphasized the principle of reinforcing Shin(腎) and rearing Jung and presented correcting inclination as the major treatment. 3. In the medication for male infertility, they presented both special decoction and common medication through analyzing clinical symptoms. Especially, they warned to be deliberate in using hot and blazing ingredients. 4. They emphasized the regimen as the way of gathering and preserving Jung. 5. The unification of Oriental and occidental medicine is the current trend in treating the male infertility. And the analysis of the causes using the advanced diagnostic exams is prominent. 6. Spleen weakness(脾虛), liver stagnation(肝鬱) and phligm stasis(痰壅) could be the cause of male infertility, but the main cause was Shin weakness(腎虛). 7. New trials such as Acupoint Injection and Heating Acupunture as well as new decoction, acupuncture and moxibustion are being explored for curing the male infertily.

정민규,조현광,우종수,안창회,서영석,김응태,박창기,오세득 영남대학교 공업기술연구소 2000 工業技術硏究所論文集 Vol.28 No.1

In this report we developed a high voltage alarm for the safety of workers who check and repair the 154kV power line. This high voltage alarm we developed is attached on workers' helmet and alarms automatically in order to let workers know when workers work over the safety distance near 154kV power line. Until now the exact safety distance hasn't been regulated and high voltage alarm we've been using was for the range of 6∼22.9kV power line. We fabricated this high voltage alarm on the basis of electric density and actual measurement of power line. The experimental result was that high voltage alarm at 66kV power line alarmed near 90cm, at 154kV power line alarmed near 160cm from the line. Accordingly, we developed the new high voltage alarm which is operated in the range of 66∼154kV power line.

카라멜화 반응 생성물의 갈색도와 항산화 효과와의 관계

신민자,윤혜현,안명수 한국조리과학회 2002 한국식품조리과학회지 Vol.18 No.6

The study was carried out to compare the relation between the color intensity and antioxidant activity of caramelization products using xylose(XY), glucose(GL), sucrose(SU), glucose+citric acid(GLCA), glucose+sodium citrate(GLSC), heated at 80, 120 and 140℃ for 24hrs, respectively. The color intensity(absorbance at 490㎚) of the browning mixtures increased as the browning temperature and time increased. But the degrees of color intensity of SU and GLCA changed very little. The hydrogen donating ability(HDA) of browning reaction products was generally enhanced as the browning temperature and time increased. When browning mixtures were heated at 80℃, the HDA of GLGC was the highest, but the HDA of GLSC was the highest when heated at 120 and 140℃. The antioxidant activities for the corn oil substrate containing the anhydrous ethanol extracts from the browning mixtures was inferior to that of SU, but was superior to that of GLCA. The relations among the color intensity, the antioxidant activity, and the hydrogen donating ability(HDA, reducing power) of the browning reaction mixtures were as follows: As the color intensity increased, the antioxidant activity decreased. The correlation coefficient of the color intensity and the antioxidant activity by regression equation was -0.73∼-0.82. As the reducing power increased, the antioxidant activity decreased. The correlation coefficient between the reducing power and the antioxidant activity by regression equation was -0.98∼-0.99. Therefore, the antioxidant activity of browning reaction mixtures seemed not correlated with the color intensity and the reducing power.
