      • Carotenoids 식이와 알코올이 혈액학적 성분과 간조직에 미치는 영향에 관한 연구

        조만희,김연선,이상한,우기민,장예진,김창세 순천향의학연구소 1999 Journal of Soonchunhyang Medical Science Vol.5 No.2

        Alcohol is well known agent which can damage the human tissues such as liver via stimulating lipid peroxidation and storage, denaturation of macromolecules, and inhibiting protein metabolism. On the other hand, carotenoids in addition to vitamins A, C, E and lipoic acid, play important roles in protecting these oxidative damages as well as preventing the production of free radicals. This study was carried out to elucidate the precise effects of alcohol administration into rats on the antioxidative functions of dietary carotenoids and isolated β-carotene, and to find out any parameters to uncover more detailed biochemical mechanisms of these agents. For these purposes, two different approaches were performed: 1) examination of the changes in hematological parameters (e.g., total proteins, A/G ratio, ALT/AST et. al) and statistical correlations among inter- and intragroups, 2) examination of the histopathological changes by an electron microscope. The results were analyzed and summarized as following; (1) Carrot diet for one week caused a slight increase in albumin. A/G ratio and AST levels, and a slight decrease in ALT, ALP, BUN and uric acid levels. Two-week alcohol administration following carrot diet increased total proteins, albumin A/G ratio and BUN levels. However, both groups were shown to have little significant changes in cholesterol concentrations. (2) Cheese diet for one week caused a significant increase in total proteins, albumin, AST, ALP, uric acid and total cholesterol levels, and a significant decrease in A/G ratio and glucose concentrations. However, two-week β-carotene diet following cheese intake increased total proteins albumin, A/G ratio, BUN and total cholesterol levels, whereas AST, ALT, ALP and uric acid levels were decreased. (3) Alcohol administration for one week caused an increase in AST activities and a decrease in total proteins, albumin, ALT, ALP and BUN levels. A successive β-carotene diet following alcohol administration increased total proteins, albumin, ALT, ALP and BUN levels, whereas decreased AST and uric acid levels. However, there were not significant changes in A/G ratio, glucose and total cholesterol levels in both groups. (4) β-carotene diet for one week caused a slight increase in albumin, glucose, AST and uric acid levels, and a slight decrease in ALP and BUN levels. Two-weeks alcohol administration following β-carotene diet increased albumin, glucose, BUN and total cholesterol levels, whereas decreased AST, ALT, ALP and uric acid levels. (5) Although the pathological investigation on the liver did not reveal significant changes, cheese diet group (CH-BC/1-CH) was shown to have some lipid deposits. Some results were unexpected and different from typical hematological changes shown by other researchers. Nonetheless, these results strongly suggest that the liver damage or hepatism caused by alcohol intake affects many kinds of biochemical metabolisms, which results in significant changes in many hematological parameters. In addition, dietary carotenoid and isolated β-carotene were shown to have protective roles against the biochemical changes by alcohol intake.

      • 알코올 투여로 온 흰쥐의 혈액성분의 변화와 간조직 손상과의 상호관계에 관한 연구

        조만희,김창세 순천향대학교 1986 논문집 Vol.9 No.2

        The white rats were divided by 3 groups; 0.6g(group A), 1.8g(group B) and 4.8g(group C) of alcohol per kg of body weight. The ethanol has been administered to the stomach with a polyethylene catheter using 20% ethanol solution for 30 days. In 5 day interval from the begining, the white rats were sacrificed to collect sample for blood analysis and histopathological observation. And the following results were obtained. 1. The most variable changes of blood components to be influenced by alcohol administration were; alcohol concentration, activities of liver ADH and GOT, numbers of RBC and WBC, amounts of triglyceride and total cholesterol and α₂-globulin fraction. 2. The liver histopathological changes, depending on the amounts and feeding days from the alcohol administration, were observed; normal finding on 1st to 10th and after then mild ballooning degeneration, necrosis of hepatic parenchymal cells in portal tract, mild infiltration of lymphocytes and fats degeneration. 3. The interrelationship between changes of blood components and histopathological damage of liver were coincide on 10th to 20th in the aspects of remarkable changes. From the above summary the amount and duration of ethanol-administration were influenced on changes of blood components and histopathological findings of liver while the early period usually 1st to 10th day was observed no more pathological changes but after then significants changes observed. From the above result there were suggested that the alcohol retaining in the body in a long period were results to appear in biochemical metabolic change.

        한방 이화주의 미백 및 피부 주름 개선 효과

        이상진(Sang-Jin Lee),권이영(Yi-Young Kwon),조성원(Sung-Won Cho),권희숙(Hee-Suk Kwon),신우창(Woo-Chang Shin) 한국식품영양과학회 2013 한국식품영양과학회지 Vol.42 No.4

        본 연구에서는 한방이화주의 피부 생리기능 활성을 알아보기 위해 70% EtOH 추출물의 피부 미백, 주름 개선 및 항염증 효과를 조사하였다. HEE은 tyrosinase 활성 억제 및 tyrosine을 기질로 melanin이 형성되는 pathway에 관여하는 주요한 인자인 TRP-1과 TRP-2를 저해하는 작용 기전을 통해 피부 색소침착의 주요 원인 물질인 melanin 생합성을 농도 의존적으로 저해하는 것을 확인하였다. HEE은 피부진피 내 피부 탄력을 유지하는 elastin을 분해하는 효소인 elastase의 활성을 저해하였고, 피부의 keratinocyte가 생성분비하는 MMP-2와 MMP-9의 단백질 발현과 proteolytic 활성을 억제하여 노화에 따른 피부 주름 생성 억제할 수 있는 가능성을 확인하였다. 또한 세포 독성 없이 LPS에 의해 유도된 염증 반응을 50% 저해하는 HEE의 농도(IC50)는 24.9 μg/mL이며, 50 μg/mL 농도로 처리하였을 때 염증 반응 저해 효과가 70%로 높은 효과를 가지는 것을 확인하였다. 이상의 결과를 종합하면 HEE의 피부 미백, 주름 개선 및 항염증에 우수한 효과를 나타내고 있으므로 기능성 화장품의 주요한 소재로 이용 가치가 높을 것으로 사료된다. Extrinsic skin aging is characterized by the loss of skin tone and resilience, irregular pigmentation, and deep wrinkles. The aim of this study was to investigate the effects of Ehwa Makgeolli containing oriental herbs (Glycyrrhiza uralensis Fisch., Lycium chinense MILL., Morus alba L., and Saururus chinensis Baill) on skin whitening and wrinkling in human skin cells. We prepared Makgeolli extracts (HEE) with 70% ethanol. HEE significantly inhibited in vitro mushroom tyrosinase activity and reduced the cellular and secreted melanin content of mouse melanoma melanocytes (B16F1 cells). HEE down-regulated the protein expression of tyrosinase related protein (TRP)-1/-2, a key player in melanogenesis. Treatment with HEE in human keratinoctyes (HaCaT cells) inhibited the proteolytic activities of matrix metalloproteinase (MMP)-2/-9 in a dose-dependent manner and dramatically reduced the expression of MMP-2/-9. In addition, HEE attenuated lipopolysaccharide (LPS)- induced nitric oxide production in murine macrophages (RAW264.7 cells). These results indicate that HEE may be a great cosmeceutical ingredient for its whitening, anti-wrinkle, and anti-inflammatory effects.

        The gonadosomatic index (GSI), gonadal development and changes in hormones in plasma level of the indoor cultured grunt (Hapalogenys nitens) were investigated by histological study from August 2011 to October 2012. The GSI showed similar trends with gonad developmental stages during the culture periods. Changes in plasma level of estradiol-17β of female H. nitens reached the highest value before the spawning period, and seasonal changes in plasma level of estradiol-17β were similar in trends of oocyte developments and GSI changes. Testosterone levels of male H. nitens reached the highest value before and after the spent stage. Ovarian developmental stages of H. nitens could be classified into early growing stage, late growing stage, mature stage, ripe and spawning stage, recovery and resting stage. The testicular developmental stages could be divided into growing stage, mature stage, ripe and spent stage, and recovery and resting stage.

        "하고초(夏枯草)"의 생약학적 연구

        황명석,조창희,박종희,Whang, Myung-Suk,Cho, Chang-Hee,Park, Jong-Hee 한국생약학회 2000 생약학회지 Vol.31 No.2

        'Ha Go Cho (夏枯草)' is one of the Chinese crude drugs used mainly as a diuretic. With regard to the botanical origin of 'Ha Go Cho', it was reported by Su et al. that those from China were originated from the fruited spica of Prunella vulgaris L. of Labiatae. It was, however, for the herba or spica of Prunella vulgaris L. var. lilacina Nakai from Korea. According to survey of markets in Korea, most of the materials collected in the markets seemed to be originated from Prunella plant, while some seemed to be Thesium plant of Santalaceae. To clarify the botanical origin of 'Ha Go Cho', the anatomical characteristics of Prunella vulgaris L. var. lilacina Nakai and Thesium chinense Turcz. were studied. As a result, it was clarified that some 'Ha Go Cho' from Korea were the herba or spica of Prunella vulgaris var. lilacina, whereas some others were the herba of Thesium chinense.

        요추 추간판탈출증 수술 후 임상 증상의 회복

        신병준,김준범,조영훈,권희,서유성,김연일,나수균,최창욱 대한척추외과학회 1997 대한척추외과학회지 Vol.4 No.2

        Study Design : The authors retrospectively analysed the recovery of clinical symptoms after surgical treatment of lumbar HIVD. Objectives : To investigate the incidence of clinical symptoms, the recovery rate and time after surgical treatment and the difference between L4-5 and L5-S1 lesion. Summary of Literature Review : There are many reports concerning the clinical result of surgical treatment for the HIVD. They usually describe the result as excellent, good, fair and poor. We can't get any information about the recovery rate and recovery time of each clinical symptom from the reports. Materials and Methods : Thirty-eight patients were treated by one level open discectomy from march 1991 to december 1995. The clinical symptoms and signs including SLR, motor deficit, sensory deficit, change of DTR and severity of radiating pain were periodically followed up on the predesigned protocol, Results : In preoperative examination, SLR was positive in 82%, motor deficit in 76%, sensory deficit in 74%, DTR change in 50%, and radiating pain in 100%. The recovery rate of SLR was 96.8%, motor deficit ; 93.6%, sensory deficit ; 78.6%, DTR change ; 21 % and radiating pain ; 84.2%. The average recovery time of SLR was 3.4 months, motor deficit ; 1.9 months, sensory deficit ; 5.3 months, DTR change ; 4.1 months and radiating pain ; 3.2 months. Motor and sensory deficit was more frequent in L4-5 lesion but DTR change was usually noted in L5-S] lesion. The recovery rate and time showed no great difference between the two level. Conclusions : The recovery rate was higher in SLR, motor deficit and radiating pain rather than sensory deficit and DTR change. The recovery time was fastest in radiating pain but variable nature was noted in sensory deficit. Above results may be helpful to explain the prognosis of the lumbar HIVD.

      • 인삼 추출액이 알코홀대사와 간조직에 미치는 영향

        조만희,이상한,김창세 순천향대학교 1987 논문집 Vol.10 No.2

        This study was carried out to investigate the effect of ginseng extract on ethanol metabolism and histopathological changes of liver tissues n alcohol administered rats. White rats of three groups(untreated normal control, A,B) were pretreated with ginseng extract (10ml/㎏ B.W) for 15 days, and then were given with combined ginseng extract-40% alcohol(group A) and 40% alcohol(group B) by polyethylene catheter through mouth for another 30 days. The description was based on the analysis of blood sample collected by 5 days interval. The results obtained were summarized as follow : 1. The mean concentrations of serum alcohol were significantly higher in group A and group B than those of control during total experimental periods. The mean concentrations of serum alcohol were significantly lower in group A than those of group B. 2. The activities of GOT and ADH, concentration of α₂-globulin, cholesterol and triglyceride were increased than those of group A, and the more lengthy period alcohol adminstered, the more increased change observed. But in alcohol-ginseng extract administered group A, these were significantly decreased in similar to those of normal control group. 3. The blood components which is markedly influenced by administration of ginseng extract were found in the followings : enzymatic activities such as GOT and ADH, contents of α-₂globulin and cholesterol. 4. With microscopic observation, hepatic tissues of group B were observed to have mild infiltration of lymphocytes from the feeding 10th day. However the moderate destruction of hepatic architecture, prominent ballooning degeneration and mild infiltration of lymphocytes were apparent from the feeding 20th day. But mild ballooning degeneration of hepatocytes was observed in periportal area in group A, whereas at the feeding 30th day, the mild infiltration of chronic inflammatory cell in the portal tract was less severe than that of group B. Based on these results It can be suggested that the activities of serum GOT and liver ADH which is most sensitively influenced by ginseng extract may have the parameter of the protective action against alcohol, in addition to protective action of ginseng against alcohol degradative effects.

        Minimize makespan of permutation flowshop using pointer network

        Cho Young In,Nam So Hyun,Cho Ki Young,Yoon Hee Chang,Woo Jong Hun 한국CDE학회 2022 Journal of computational design and engineering Vol.9 No.1

        During the shipbuilding process, a block assembly line suffers a bottleneck when the largest amount of material is processed. Therefore, scheduling optimization is important for the productivity. Currently, sequence of inbound products is controlled by determining the input sequence using a heuristic or metaheuristic approach. However, the metaheuristic algorithm has limitations in that the computation time increases exponentially as the number of input objects increases, and separate optimization calculations are required for every problem. Also, the heuristic such as dispatching algorithm has the limitation of the exploring the problem domain. Therefore, this study tries a reinforcement learning algorithm based on a pointer network to overcome these limitations. Reinforcement learning with pointer network is found to be suitable for permutation flowshop problem, including input-order optimization. A trained neural network is applied without re-learning, even if the number of inputs is changed. The trained model shows the meaningful results compared with the heuristic and metaheuristic algorithms in makespan and computation time. The trained model outperforms the heuristic and metaheuristic algorithms within a limited range of permutation flowshop problem.
