Hepatoid carcinoma is a primary extrahepatic carcinoma whose morphology, immunohistochemistry, and behavior are similar to those of hepatocellular carcinoma. The most common sites of extrahepatic carcinoma are the stomach and ovary, but nine cases of hepatocellular differentiation of the pancreas have been reported in the literature. We report another case of hepatoid carcinoma of the pancreas that was associated with the development of a pancreatic endocrine carcinoma in a 46-year-old man. Serum alpha-fetoprotein (AFP) was elevated to 262.49 IU/mL and radiological examinations revealed a mass measuring 7.5 cm in diameter in the head of the pancreas. He underwent a conventional Whipple operation, and light microscopy showed adenocarcinoma that was immunopositive for AFP, hepatocyte antigen, cytokeratin, chromogranin, synaptophysin, and alpha-1 antichymotrypsin. Although hepatoid differentiation was not shown unequivocally histologically, other immunohistochemistry findings supported the diagnosis of hepatoid carcinoma combined with neuroendocrine carcinoma. The patient was healthy and had no evidence of recurrence at 4 months after the surgery. This report describes why hepatoid carcinoma should be considered as a differential diagnosis of a pancreatic mass, especially when serum AFP is elevated. (Gut Liver 2010;4:98-102)

Objective: The aim of this study was to determine the correlation between clinical variables such as body mass index, blood pressure, drug use and oxidative stress level in children and adolescents with attention deficit and hyperactivity disorder (ADHD). Methods: Total oxidant status (TOS), total antioxidant status (TAS), oxidative stress index (OSI), malondialdehyde (MDA) and superoxide dismutase (SOD) activity were measured in the serum of 51 patients (38 male, 13 female) diagnosed with ADHD according to DSM-5 diagnostic criteria and 32 control subjects (12 male, 20 female). The Kiddie Schedule for Affective Disorders and Schizophrenia Present and Lifetime Version was applied to all participants. Results: The mean TOS, OSI, MDA values were determined to be significantly higher (p < 0.001) and the mean SOD value was lower in the ADHD group (p < 0.001). Multivariate regression analysis indicated significantly lower SOD and diastolic blood pressure values and significantly higher MDA in the ADHD group compared to the control group (p < 0.01). Low SOD (sensitivity 90.2%, specificity 78.0%) and high MDA (sensitivity 86.3%, specificity 81.2%) were determined to be predictive parameters for diagnosing ADHD. In univariate analysis, the mean TOS, OSI and SOD values were higher in ADHD patients under medication, while the mean TAS was higher in patients not using medication (p < 0.01). Only TOS was significant in multivariate logistic regression analysis (p < 0.01). Conclusion: The results of this study demonstrate that impaired oxidative balance may play a role in the etiology of ADHD.

HPLC상으로 total ginsenoside의 함량을 측정한 결과 백삼 28.20mg/g, 홍삼 421.10mg/g이고 A1~A9에서는 46.10~76.80mg/g으로 홍삼과 백삼보다 증자 횟수가 증가 할 수록 total ginsenosied 함량이 증가하였다. 3. HPLC상에서 분석한 증자 횟수별 인삼의 ginsenosides(G-Rb₁, -Rb₂, -Rc, -Rd, -Re, -Rf, -Rg₁, -Rg₂, -Rg₃)의 함량변화는 G-Rc, -Rd, -Re는 1회 증자한 A1에서 함량이 증가 하다가 증자 횟수가 증가 할수록 다시 함량이 감소하였으며, G-Rg₂, -Rg₃는 증자 횟수와 비례하여 함량이 증가하는 경향을 보였다. 4. 인체유래 간암세포(Hep3B)에서의 항암효과 검증실험에서는 물, 60%에탄올 추출물을 각각 1000ppm, 2500ppm, 5000ppm으로 처리 한 후 세포 증식 억제율을 확인하였다. 백삼은 모든 처리군에서 미미한 증식억제 효과가 있었으나, 홍삼은 60%에탄올 추출물 5000ppm에서 54.52%, A9에서는 96.28%의 현저한 세포증식억제 효과가 있었다. A9가 Hep3B에 대해서 백삼과 홍삼보다 세포 증식 억제율이 더 높은 것을 확인 할 수 있었다. 이상의 결과로 볼 때 약주를 이용해서 증자한 홍삼이 백삼이나 일반홍삼보다 총 사포닌, 진세노사이드의 함량이 증가하였고, 기능과 효능이 증강된 것으로 확인되어 우수함이 입증되었다. 또한, 홍삼정과, 절편정과 등 제품의 다양화와 품질개선에 기여할 것으로 기대된다. 향후 증자 방법, 압력, 온도, 및 약주 등의 제조 조건에 따른 지속적인 연구가 요청된다. This study takes place to establish basic data to develop various ginseng-processing methods and products. It analyzed components and quantity of ginsenoside in red ginseng after brewing with the traditional medicinal wine as well as the brownness and impurity level changes, and verified anti-oxidization and anti-cancer effects. The following is the founding of these analyses. To examine the changes in the brownness of white and red ginseng, premonitory materials of 60% ethanol extracts were examined As the result of these examinations, all of the values of examined matters premonitory materials, mid products, Fufural, coloring matters and impurity level were increased as the brewing continued. And the brownness level for white and red ginseng was similar in Al and the values were relatively high in A3. The total Ginsenoside on HPLC was 28.20㎎/g for white ginseng and 42.10㎎/g for red ginseng. The quantity of total Ginsenoside was increased as the brewing continued as 46.10∼76.80㎎/g was shown in A1∼A9. To see the quantity changes of Ginsenosides(G-Rbi, -Rte, -Re, -Rd, -Re, -Rf, -Rg₁, -Rg₂, -Rg₃) contained in ginseng on HPLC, the quantity of G-Rc, -Rd, -Re were increased in Al the first brewing and decreased as the brewing continued. The quantity of G-Rg2, -Rg3 was increased proportionate to the number of times for brewing. In an anti-cancer test in liver cancer cells(Hep3B) extracted from human body, each of water and 60% ethanol extracts were processed with 1000ppm, 2500ppm, and 5000ppm and checked the multiplication restrain rate. All of the processing groups in white ginseng have minimum multiplication restrain rates, but red ginseng has 54.52% at 60% ethanol extract 5000ppm. At A9, 96.28%) of cell multiplication restrain effects were shown. Comparing Hep3B to A9, white ginseng has higher restrain effects than red ginseng. As seen in the above results, the reinforced red ginseng using the medicinal wine has higher total saponin and ginsenosides, as well as with increased functions and effects leading the superiority. And it is possible to use Red Ginseng Jung Kwa; Jung Kwas with flower pattern imprinted, and expect to increase the opportunities to use the extracts. Later, when brewing the pressure, temperature, and medicinal wine can be examined to continuous studies.

Human take in many kinds of foods, and also are exposed to various chemicals which may be harmful. Especially, some food and chemicals may give rise to free radicals during metabolism in the tissues. These free radicals, such as superoxide. hydroxy radical and hydrogen peroxide, induce oxidations of the macromolecules, which can cause a variety of damages in the body. But human have anti-oxidative mechanisms well developed against these damages. Anti-oxidants such as vitamines A, C, E, and β-carotene are believed to have a major role in these mechanisms acting as a cofactor of anti-oxidative system. On the basis that alcohol is one of the most common chemicals that induce oxidative damages in liver, this study was carried out to elucidate biochemical changes of blood after alcohol administration as well as to investigate the effects of β-carotene on the alcohol-injected Sprague-Dawley rats. The following results were obtained from this study. At first, the number of WBC after one week were lowest in the alcohol-treated group. But, β-carotene treatment by oral injection was shown to diminish the increasing rate of WBC in the alcohol-treated group. Second, RBC was increased all the time in all groups tested with alcohol and/or β-carotene. It is of interest that there was a sudden increase of RBC in the alcohol-treated group. Third, Hb was increased in the alcohol-treated groups on the second week. On the other hand, the groups of β-carotene treatment showed more higher rate of increase in Ht and MCV. It is of note worthy that these effects were maximized in the group of β-carotene treatment followed by diet with cheese for a week. Finally, alcohol had little or no effect on MCH and MCHC, although β-carotene showed atypical effects. These results made it clear that alcohol can cause damages in liver, resulting in inflammation and increase of RBC. Also β-carotene is believed to protect liver from oxidative effects by alcohol. In according to these results, it is suggested that diet of anti-oxidants such as Vt. A, B, C, E, and β-carotene is strongly recommended to prevent certain diseases caused by oxidative damages.

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.

Trousseau's syndrome refers to an association of thrombosis with visceral malignancy. The thrombophlebitis is usually recurrent and migratory. An episode of thrombosis may precede clinical recognition of malignancy by weeks or months and in many cases, the underlying malignancy was occult. Patients with a recurrent deep venous thrombophlebitis without a known predisposing factors for hypercoagulable state deserves a consideration for underlying malignancy. We report a patients with lung cancer who initially demonstrates the clinical features of the Trousseau's syndrome.
