동결온도가 해동우육의 품질에 미치는 영향을 검토하였다. 해동드립감량은 -3℃ 동결이 30일째에 3.4%, -20℃ 동결이 60일째에 1.8%로 높았으며, -3℃가 -20℃보다 드립량이 많았다. 가열감량은 water bath와 pan 가열 모두 저장초기보다 동결저장중에 현저하게 높았으나, 동결온도에 의한 차이는 없었다. 염용성 단백질의 추출성은 동결기간이 경과함에 따라 감소하였고, -20℃에서 동결한 것이 -3℃에서 동결한 것보다 추출성이 높았다. 수용성 단백질의 추출은 -3℃의 경우 동결기간에 따라 현저한 변화가 없었으나, -20℃에서 동결한 것은 동결기간에 따라 증가하는 경향을 보였다. 명도(L)는 동결초기가 높았고 적색도(a)는 동결기간에 따른 변화가 없었으며, 황색도(b)는 동결초기보다 동결중에 더 높았다. Myoglobin의 변성율은 -3℃의 경우 45일째, -20℃의 경우 15일째 각각 94.4%와 94.0%로 가장 높았다. 전단력가는 동결초기보다 저장기간이 경과함에 따라 높아졌으며, 근원섬유의 소편화도는 동결저장중 현저한 변화가 없었다. pH는 -3℃와 -20℃ 모두 30일째까지 높아지다가 그 이후 낮아지는 경향을 나타내었다. This study was carried out to investigate the effects of freezing temperature on quality of thawed beef loin. In case of thaw drip loss, the freezing of -3℃ and -20℃ were higest by 3.4% to 30 days and by 1.8% to 60 days, respectively. And the thaw drip loss of -3℃ freezing was more than -20℃ freezing. The cooking loss of water bath and pan boiling were increased significantly during freezing than the beginning of freezing, but were not different -3℃ and -20℃. The salt soluble protein extractability was decreased during freezing, the -20℃ freezing was higher than -3℃ freezing. The water soluble protein extractability of -3℃ freezing was not significant different during freezing storage, that freezed at -20℃ was increased during freezing. The "L" value of the beginning of freezing was higher than during freezing, the "a" value was not different during freezing, and the "b" value during freezing was higher than the beginning of feezing. The myoglobin denatured percentaged of the -3℃ and -20℃ freezing were highest by 94.4% to 45 days and by 94.0% to 15 days, respectively. The shear force value during freezing was higher than the beginning of freezing, the myofibrillar fragmentation index was not significant different during freezing. The pH was increased to freezing 30 days, after that was decreased.

Objectives : To observe the effect of acupuncture treatment and western medical treatment on frozen shoulder patients. Methods : 39 voluntary patients were randomly assigned to the Eastern treatment group(E group, n=22) and the Western treatment group(W group, n=17). The E group received acupuncture treatment on LI15, TE14, GB21 and Master Dong's acupuncture points, Shin-gwan and Gyun-joong, twice a week for 4 weeks. The W group received suprascapular nerve block, subacromial injection and trigger point injection, twice a week for 4 weeks. Both groups were instructed to practice self exercise during their daily lives. Evaluations were made before treatment and after treatment using Constant Shoulder Assessment(CSA), Shoulder Pain and Disability Index(SPADI) and the patient's satisfaction concerning the treatment was measured by Visual Analogue Scale(VAS). The obtained data were analyzed and compared. Results : The E group showed significant improvement(p<0.05) according to the CSA and SPADI. The patient's satisfaction scored 5.67 on a scale of 10. The W group showed significant improvement(p<0.05) according to the CSA and SPADI. The patient's satisfaction scored 7.73. But the difference between the two groups were insignificant according to CSA and SPADI. Conclusion : Both acupuncture and nerve block treatment significantly improved frozen shoulder. But the difference of the two treatments was insignificant.

연구 배경 : 본 연구는 정신분열증 환자에서 흡연 여부에 따라 정신분열증 환자군의 정신과적 과거력 및 현재 증상, 치료 반응과 인지 기능 등에 어떤 차이가 있는 지를 알아보려는 것이다. 연구 방법 : 정신분열증 환자 중 36명의 흡연군과 31명의 비흡연군을 연구 대상으로 하였다. 현재의 증상을 평가하기 위해서 양성 및 음성 증상 척도(Positive & Negative Syndrome Scale) 및 전반적 기능 평가 척도(Global Assessment Scale)를 상용하였고, 추체외로계 부작용을 추체외로계 부장용 평가척도(Rating Scale for Extrapyramidal Side Effects)로 측정하였다. 흡연군과 비흡연군의 인지 기능을 평가하기 위해 비엔나 검사 중 SPM(Standard Progressive Matrices), Cognitron 및 FFA(Flicker Fusion Analyzer) 검사를 실시하였다. 연구 결과 : 1) 흡연군과 비흡연군에 비해 유병 기간이 유의하게 길었음에도 불구하고, 입원 시의 증상 정도(PANSS 총점)가 유의하게 낮았고, 기능 정도(GAS 점수) 역시 유의하게 높았다. 2) 정신분열증의 치료 반응에 영향을 미칠 것으로 생각되는 나이와 유병 기간을 통제한 상태에서 흡연여부에 따른 치료 반응의 차이를 검증해 본 결과, 흡연 여부에 따른 일일 약물 사용량, 추체외로계 부작용 및 증상 호전율(PANSS 호전율)이나 기능 호전율(GAS 호전율)에 유의한 차이는 없었다. 또한 인지 기능에 영향을 미칠 것으로 생각되는 나이, 유병 기간, 항전신병약물 용량 및 증상의 정도를 통제한 상태에서 흡연 여부에 따른 인지 기능의 차이를 검증해 본 결과, 흡연 여부에 따른 SPM 값, COG-R 및 FFA 갑의 차이는 없었다. 3) 흡연군 내에서 흡연 정도와 치료 반응 및 인지 검사 점수와의 관계를 알아보기 위해, 나이와 유병 기간 요인을 통제한 상태에서 일일 평균 흡연량과 여러 임상 척도와의 상관 관계를 분석해 보았다. 그 결과 일일 흡연량과 증상 호전율(PANSS 호전율) 이나 기능 호전율(GAG 호전율) 사이에 통계적으로 유의한 상관 관계를 보였다. 그러나 총 흡연 기간은 치료 반응 및 인지 기능과는 통계적으로 유의한 상관 관계를 보이지 않았다. 결 론 : 이상의 결과를 종합해 보면 흡연 정신분열증군은 비흡연 정신분열증군에 비해 입원 시 증상이 경미하고 기능이 좋으며, 흡연 정신분열증군에서는 흡연량이 많을수록 치료 시 증상 및 기능이 호전율이 높다고 할 수 있다. 그러나 흡연군에서 일일 약물 사용량이 높다거나, 추체외로계 부작용이 덜 나타난다거나 지능 저하가 덜하다는 이전의 연구 결과들은 입증되지 않았다. Objectives : The purpose of this study was to examine the differences of past histories, current symptoms, treatment responses and cognitive and functions between smoking and nonsmoking schizophrenic patients. Methods : The subjects were composed of 67 schizophrenic patients including 36 smokers and 31 non-smokers. They were examined by psychiatric history checklist, Simpson and Angus's rating scale for extrapyramidal side effects, positive & negative syndromes scale(PANSS), global assessment scale(GAS), and Vienna test including Standard Progressive Matrices(SPM), Cognitron, and Flicker Fusion Analyzer(FFA). Results : The results were as follows : 1) Although the duration of illness of smokers was longer than that of non-smokers, the smokers had significantly higher score of GAS and significantly lower score of PANSS than non-smokers at admission. 2) With effects of age and duration of illness controlled, there were no differences of mean dosage of neuroleptics, extrapyramidal side effects, PANSS improvement rate and GAS improvement rate between both groups. 3) With effect of age, duration of illness, and total PANSS score controlled, there were no differences of score of SPM, cognitron, and FFA. 4) In smokers, the PANSS improvement rate and the GAS improvement rate were positively correlated with mean number of daily smoked cigarettes, with effects of age and duration of illness controlled. Conclusions : In schizophrenic patients, smokers had less severe symptoms than non-smokers. In smokers, the PANSS improvement rate and the GAS improvement rate were positively correlated with mean number of daily smoked cigarettes. But Smokers were not proven to have received higher dosage of neuroleptics, to have lower extrapyramidal side effects, or to have less severe impairment of cognitive function.

The purpose of this study was to provide basic materials for the supply of the high quality of meals which meets the need of patients of university hospital in G city, affording the increase their quality and to make proper preparations through the analysis of the cause of leftover food for the improvement of hospital service and for the efficiency of hospital management. For this study, questionnaires from the total 302 patients hospitalized (1st 149, 2nd 100 and 3rd 53 investigated persons) during May 28 to October 28, 2001 were used and the measurement of leftover food was performed in each hospital ward for 1 week. A tool of research was consisted of the total 22 structured questionnaires to improve satisfaction of patient meal and to reduce leftover food, For the distribution of meals, the contents of improved education are 1) The improved ways for the satisfaction of rice and soup were searched 2) Several kinds of Kimchi were diversified 3) Kindness education was repeatedly performed to all distributors for 20 minutes every Thursday afternoon ;1) The preparation of clean meals was educated and supervised 5) Since there was much leftover food, when patients enter hospitalization and leave the hospital, and they change meals, and they miss changed meals, both official document and oral cooperation were requested to each hospital ward person in charge. The research results are as follows: 1. In food quality and service, the negative opinion was shown in the item of food temperature, food amount, cleanness of dinner table, kindness of food distributor. And the positive opinions of Eat much. Eat by half. in the item of food intake amount supplied by the hospital were shown. It was investigated that the leftover food was due to the great amount of food. 2. In the determination of leftover food among several hospital wards, 63 hospital ward (medical treatment hospital) gave the largest leftover food in the first and the second investigation. In the third investigation, 73 hospital ward with long-term patients among hospital wards with the largest leftover food gave the order of soup-kimchi-rice, kimchi-soup-rice as leftover foods. Summarizing these results, it is considered that the reduction of leftover food by the improvement education in hospital meals distribution might help the nutrition intake as well as service improvement in hospital manger and social benefit.

Background : CD14 is the receptor for lipopolysaccharides and heat shock protein (HSP), which has been suggested being associated with increased risk of coronary artery disease (CAD). We investigated whether the response to infectious agents or HSP is different according to CD14 polymorphism in Koreans. Materials and Methods : Antibody titers to Helicobacter pylori, Chlamydia pneumoniae, and human HSP60 (hHSP60) were measured in 48 patients with stable CAD and in 41 healthy controls by ELISA. CD14 genotype was determined by PCR and high-sensitivity C-reactive protein (hs-CRP) was measured. Results : Seropositivity to C. pneumoniae and H. pylori, and antibody titer to hHSP60 were not significantly associated with the presence of CAD. CD14 genotype distribution was 31 TT (35%), 43 CT (48%), and 15 CC (17%). To compare the response to the infectious organism and hHSP60, we divided study population into 3 groups; CAD patients with non-TT genotype (group I, n=30), CAD patients with TT genotype (group II, n=18), and normal controls (group III, n=41). Seropositivity to C. pneumoniae and H. pylori, and antibody titer to hHSP60 were not significantly different among 3 groups. Though hs-CRP level was significantly different among 3 groups, post-Hoc analysis showed that hs-CRP level was not significantly different between group I and group II (group I: 1.6[1.1-3.5] mg/L and group II: 0.35[0.1-2.0] mg/L). Conclusions : This study suggests that the inflammatory responses to infectious organisms and HSP do not differ according to the CD14 genotype in Koreans. 목적 : 만성적인 세균 감염이나 자가 면역 반응이 동맥경화와 연관되어 있다는 주장이 제기되어 왔다. CD14은 lipopolysaccharides (LPS)와 heat shock protein(HSP)의 수용체로 C(-260)→T 다형성이 관상동맥 질환의 위험과 관련되어 있다고 제안되어 왔다. 본 연구에서는 한국인에서 CD14 다형성에 따른 LPS와 HSP에 대한 반응성을 염증표지자를 측정하여 살펴보고자 하였다. 재료 및 방법 : 안정형 관상동맥 환자 48명과 정상 대조군 41명을 대상으로 Chlamydia pneumoniae, Helicobacter pylori 항체 및 인체 HSP60 (hHSP60) 항체 역가를 enzyme-linked immunosorbent assay (ELISA) 방법으로 측정하였다. CD14 유전자형은 중합효소연쇄반응을 이용하여 결정하였고 hs-CRP를 측정하였다. 결과 : C. pneumonias 및 H. pylori 항체 양성 여부 및 항체 역가, 그리고 hHSP60에 대한 항체 역가는 안정형 관상동맥 질환의 유무와 유의한 상관관계는 없었다. CD14 유전자형의 분포는 TT 30명(39%), CT 31명(40%), 그리고 CC 16명(21%)이었다. 관상동맥 질환 군에서 TT 유전자형은 38%, 대조군에서는 32%로 TT 유전자형과 관상동맥 질환의 유무와는 유의한 상관관계가 발견되지 않았다(P>0.05). CD14 유전자형에 따라 C. pneumonias와 H.pylori 감염 및 hHSP60에 따른 반응에 차이가 있는지 여 부를 알아보기 위해, 관상동맥 질환 군을 다시 TT 유전자형 군과 non-TT 유전자형 군으로 나누어, 전체적으로 세군에서 항체 양성률과 역가를 비교하였다(I군: CD14 TT 유전자형을 가진 안정형 관상동맥 환자, II군: CD14 TT 유전자형을 가진 안정형 관상동맥 환자, III군: 정상 대조군). 세 군에서 C. pneumonias와 H. pylori 항체 양성률 및 hHSP60 항체 역가에는 유의한 차이가 없었다. 세 군사이에 hs-CRP 값에 유의한 차이가 있었지만, post-Hoc분석에서 II군의 hs-CRP 값이 I군에 비해 유의하게 높지는 않았다(0.35 [0.1-2.0] mg/L in group II vs. 1.6 [1.1-3.5]mg/L in group I, P>0.05). 결론 : 본 연구는 한국인에서 CD14 유전자형에 따라 LPS나 HSP에 대한 반응이 유의하게 다르지 않음을 시사한다.

Predehydration effects for cryopreservation in -196℃ liquid nitrogen were studied in carrot(Daucus carota Sativa DC) and millet(Setaria italica BEAUVOIS) seeds. 5 cultivars of carrot seeds were adjusted to moisture contents between 2 and 6% by air dry treatments. Besides 3 cultivars of millet seeds were adjusted to moisture contents about 6%. Seeds were placed in paper envelopes after submerged in liquid nitrogen and rewarming in 38℃ water. Seeds moisture contents by duration of drying were identified as controlling factors in the survival of several crop seeds for cryopreservation. The carrot seeds having approximate 5% moisture content were able to withstand cooling to -196℃. Undehydrated seeds of carrot after being cryopreservated in liquid nitrogen have about 30% of moisture content and show 0-5% in germination. The millet seeds dehydrated by drying for 30-180 min. to have 4-8% of moisture content before cryopreservating show 90% above in germination test. Any morphologically deformity in germinating beds has not been observed. Results from this study suggest that Aquilegia species seeds can cryopreservation in liquid nitrogen if the seed moisture content is controled by a proper amount of dehydration.

김주영,남계현,김태희,이권해,이해혁,배동한 순천향의학연구소 2003 Journal of Soonchunhyang Medical Science Vol.9 No.2

Objective: TRAIL(also called Apo-2L) is a member of the tumor necrosis factor(TNF) family of cytokines which induces apoptosis cell death in a variety of tumor cell lines. It mediates its apoptotic effects through one of two receptors, DR4 and DR5, which are members of the TNF receptor family, and whose cytoplasmic regions contain death domains. TNF and Fas ligand induces apoptosis in tumor cells; however, their severe toxicity toward normal tissues hampers their application to cancer therapy. We examed if paclitaxed and/or Apo-2LTRAIL induces apoptosis of cervical cancer HeLa, SiHa, ME-180, and CaSki cells. Mehods : We have demonstrated that paclitaxel and Apo-2L/TRAIL induces apoptosis of cervical cancer HeLa, SiHa, CaSki and ME-180 cell lines in a dose-dependent manner. HeLa, SiHa, ME-180 and CaSki were obtained from American Type Culture Colection. Recombinant Human TRAIL(Chmicon). DR4 and DR5 were purchased from Santa Cruz. Paclitaxel, MTT assay Kit, Acridine orange and Ethium bormide were purchased from Sigma. HeLa and SiHa were grown in DMEM. ME-180 and CaSki were grown in RPMI. Tripan blue stain and MTT assay were done for cytotoxicity. Annexin V-FITC and PI(propidium iodide) flowcytometry for apoptosis assay. DR4 and DR% were expressed by Western Blot. Fluorescent Microscopy used Acridine orange(AO) and Ethium bromide(EB). Results : Importantly, concurrent treatment of cervical cancer cells with paclitaxed and Apo-2L/TRAIL induces significantly more apoptosis than Apo-2L/TRAIL alone. Conclusion : We need further studies which reveals possible therapeutic potential in the women with cervical cancer by suing Apo-2L/TRAIL.
