  • 본 연구에서는 내분비계 장애물질으로 알려져 있고, 플라스틱 제품의 가소제로 사용되고 있는 di-(2-ethylhexyl) phthalate (DEHP)가 흰쥐의 간세포 미세구조와 간조직내 metallothionein (MT)의 발현 양상에 미치는 영향을 조사하였다. DEHP는 흰쥐 간세포의 미세구조와 MT 발현에 영향을 주었다. 실험군의 경우 조면소포체가 발달하고, 미토콘드리아가 증가하며 리소솜 혹은 퍼옥시좀들이 증가하는 경향을 나타냈다. 한편, MT 발현의 변화를 면역세포 화학적 방법과 western Blot을 수행한 결과 저농도 투여군에서는 약 1.5배, 고농도 투여군에서는 약 2배 가량 증가하는 결과를 나타냈다. 결론적으로 DEHP는 흰쥐 간세포의 구조와 기능에 영향을 주는 것으로 판단되며, 이러한 세포내 스트레스가 MT 발현 증가 현상과 연관이 있을 것으로 판단된다.

  • 본 연구에서는 비타민과 무기질을 sub-optimal 수준으로 섭취시키고 고콜레스테롤식이와 에탄올을 병행 섭취시키는 흰쥐를 대상으로 5주간 생식제품을 20% (생식20군) 및 40% (생식40군) 수준으로 보충 섭취시킨 후, 체내 항산화체계에 미치는 영향을 평가하여 다음과 같은 결과를 얻었다. 일일 식이섭취량, 체중증가량 및 식이효율은 일반대조군과 영양불균형대조군 간에 유의적인 차이가 관찰되지 않았고, 생식40군의 경우 영양불균형대조군에 비해 식이효율이 유의하게 향상되었다 (p < 0.05) . 간조직의 지질과 산화물농도는 일반대조군에 비해 영양불균형대조군에서 유의하게 더 낮았으며 (p < 0.05), 식이내 생식첨가에 의해 영향을 받지 않았다. 간조직의 SOD 활성은 일반대조군에 비해 영양불균형대조군에서 유의적으로 증가하였고, 생식 섭취군의 경우 영양불균형대조군에 비해 유의하게 감소하였다 (p < 0.05), 간조직의 catalase 활성은 영양불균형대조군에서 일반대조군에 비해 유의하게 더 낮았으며 (p <0.05), 생식섭취에 의해 영향을 받지 않았다. 간조직의 (GSH-Px + catalase)/SOD 비율은 영양불균형대조군에서 일반대조군보다 유의하게 더 낮았으며, 영양불균형대조식이에 생식을 20% 수준으로 첨가시킨 결과 유의하게 증가하였다 (P < 0.05). 영양불균형대조식이는 일반대조식이에 비해 혈중 Cu 농도를 유의하게 증가시켰다. 생식분말 섭취군의 경우 영양불균형대조군에 비해 Fe, Se, Mn, Zn 및 Cu 등의 무기질 섭취량이 더 많음에도 불구하고 혈중 농도는 오히려 더 낮게 나타났으며, 특히 Fe 및 Cu농도는 유의적으로 감소하였다. 이는 생식제품이 phytate 및 섬유질이 풍부한 전곡류 및 식물성식품들로 구성되어 있어 무기질의 생체이용률을 저하시키기 때문으로 사료되며, 생식제품의 장기 섭취시 이들 무기질 영양상태가 저하되지 않도록 주의가 필요할 것으로 생각된다.

  • The present experiment was performed in order to know the treatment effect of aquapuncture with hepatonics on recovery in artificially induced hepatic damaged dogs by carbon tetrachloride. The animals were divided into a control and two experimental groups (aquapuncture with taurine into Gan-su acupoint: Aa-I group and aquapuncture with taurine into blank acupoint in the thigh: Aa-II group). The changes of serum enzyme activities (ALT, AST and ALP), serum total protein contents, protein fractions and pathohistological findings of the liver were examined after application of aquapunctiuf treauent The results obtained through this experiment were summarized as follows : The serum ALT activities tendeded to decrease in experimental group compared with those of control group. Significances were detected at 5th (p<0.05) and 7th (p<0.05) day in Aa-I group and 7th day (p<0.05) in Aa-II group, respectively. Low value was fecund in Aa-I group compared with Aa-II groups but significance was not observed between two experimental groups. The serum AST activities in experimental group showed decreasing tendency compared with those of control group. Significances were observed at 2nd (p<0.05) and 5th (p<0.05) day in Aa-I group and 2nd (p<0.05) day in Aa-II groups respectively. Aa-I group showed lower values than those of Aa-II groups however, no significance was detected between experimental groups. The serum ALP activities of experimental group showed a slight decrease compared with those of control group, however, significance was not detected among all groups. The serum total protein content in experimental group showed tendency of increase compared with control group. Significance was found at 2nd day (p<0.05) in Aa-I group, but there was no significance in Aa-II group. Further significant increase of total protein content was seen at 1st day (p<0.05) in Aa-I group compared with Aa-II group. The change of serum albumin content in experimental group showed tendency of increase compared with control. Significant increases were detected at 1st (p<0.01) and 2nd (p<0.01) day in Aa-I group, respectively. Aa-II group showed increase compared with control groups but significance was not observed. Further significant increase was at 1st day (p <0.05) in Aa-I group compared with Aa-II group. The change of ${\beta} $-globulin in Aa-I group was slightly decreased compared with control group. Aa-II group was similar to controls but significance was not observed among all groups. The change of P-globulin content in Aa-I group showed tendency of increase compared with control and Aa-II group showed the tendency of decrease compared with control. The change of ${\gamma}$-globulin content experimental group showed tendency of increase compared with control, however, significance was not detected among groups. The change of A/G ratio in Aa-I group showed tendency of increase compared with control group and Aa-II group was similar to controls but no significance was found among groups. As for pathohistological observations the grade of hepatocellular vacuolized degeneration and necrosis in Aa-I group was milder than those of control and Aa-II groups and the change of Aa-II group was similar to that of control. Considering above finding collectively, it was thought that aquapuncture of Gan-su acupoint with hepatonics was more effective than aquapuncture of blank acupoint for the recovery of hepatic damage.

  • The technique of stem cells or hepatocytes transplantation has recently improved in order to bridge the time before whole-organ liver transplantation. In the present study, unfractionated bone marrow stem cells (BMSCs) were harvested from the tibial and femoral marrow compartments of male mice, which were cultured in Dulbecco's modified Eagle's medium (DMEM) with and without hepatocyte growth factor (HGF), and then transplanted into Schistosoma mansoni- infected female mice on their 8th week post-infection. Mice were sacrificed monthly until the third month of bone marrow transplantation, serum was collected, and albumin concentration, ALT, AST, and alkaline phosphatase (ALP) activities were assayed. On the other hand, immunohistopathological and immunohistochemical changes of granuloma size and number, collagen content, and cells expressing OV-6 were detected for identification of liver fibrosis. BMSCs were shown to differentiate into hepatocyte-like cells. Serum ALT, AST, and ALP were markedly reduced in the group of mice treated with BMSCs than in the untreated control group. Also, granuloma showed a marked decrease in size and number as compared to the BMSCs untreated group. Collagen content showed marked decrease after the third month of treatment with BMSCs. On the other hand, the expression of OV-6 increased detecting the presence of newly formed hepatocytes after BMSCs treatment. BMSCs with or without HGF infusion significantly enhanced hepatic regeneration in S. mansoni-induced fibrotic liver model and have pathologic and immunohistopathologic therapeutic effects. Also, this new therapeutic trend could generate new hepatocytes to improve the overall liver functions.

  • Objectives: This study was undertaken to investigate the effects of Gugijagami-bang (GGB) in a hyperlipidemic animal model induced by a high-fat diet using diverse biological methods. Methods: This study was to determine whether fractionated GGB extracts inhibit reactive oxygen species (ROS) and nitric oxide (NO) in RAW 264.7 cells. Hyperlipidemia was induced by a high-fat diet fed for 6 weeks. Total cholesterol, LDL cholesterol, HDL cholesterol, triglyceride, liver function and histologic change of liver were measured after oral administration of GGB. Results: 1. DPPH scavenging bow performance was increased in a concentration-dependent manner by GGB. 2. Compared to the control group, NO production (%) and ROS production (%) were decreased significantly by GGB. 3. Total-cholesterol, LDL-cholesterol, triglyceride were decreased significantly by GGB. 4. HDL cholesterol increased more than the control group, but not significantly. 5. In histopathologic examination, fatty liver (hepatic steatosis) was inhibited, almost no rounds of fat were observed in the liver. Conclusions: GGB would appear effective in the prevention and treatment of atherosclerosis, ischemic heart disease, other cardiovascular diseases caused by hyperlipidemia.

  • Lepidium meyenii, known as Maca, is traditionally employed in the Andean region for its supposed properties to improve energy and fertility. In the present study, we investigated the effects of gelatinized and fermented Maca on improvement of physical stamina and epididymal sperm counts, and on blood biochemical parameters related to fatigue and tissue injury: creatine phosphokinase, aspartate transaminase, lactate dehydrogenase, blood urea nitrogen, glucose, total cholesterol and total proteins. Adult male mice was divided at random into two main groups (resting and excercise groups). The excercise group was separated into three subgroups (exercise only, exercise with gelatinized Maca and fermented Maca-treatment groups). Gelatinized or fermented Maca (800 mg/kg) were orally administered for 30 days. All animals in exercise groups were subjected to daily 30-min swimming for 28 days 30 min after Maca treatment. Daily exercise decreased the body weight gain, and fermented Maca further attenuated the body weight increase. Gelatinized and fermented Maca significantly increased the maximum swimming time on 14 and 28 days of treatment (p<0.05), respectively, suggestive of a long-term stamina-enhancing effect of fermented Maca. Both Maca fully or significantly recovered blood parameters of energy as well as muscular and hepatocytic injuries changed by repeated exercise and maximum swimming performance (p<0.01). Moreover, gelatinized and fermented Maca increased epididymal sperm counts 22.0% and 32.0%, respectively. In conclusion, the results indicate potential benefits of Maca for improving both physical stamina by minimizing muscular and hepatic damage and preserving energy during swimming exercise and male reproductive function by increasing epididymal sperm counts.

  • Ando et al found the root of Ginseng contained an active peptide which had anti-lipolysis funrtion when they studied effective components of Ginseng to cure diabetes mellitus in 1980. In recent years we were making lots of the researches on the Ginseng polypeptide. We obtained a 14 peptide which could decrease levels of blood sugar and hepatic glycogen. However, amino acid composition of the peptide differs from one reported by Ando et al. The results of its purification, structure and functure and function were reported in this paper.

  • The analgesic effect of morphine was antagonized and the development of tolerance was suppressed by the modification of the neurologic function in the animals treated with ginseng saponins The activation of the spinal descending inhibitory systems as well as the supraspinal structures by the administration of morphine was inhibited in the animals treated with ginseng saponine intracerebrally or intrathecally. The development of morphine tolerance and dependence, and the abrupt expression of naloxone inducted abstinence syndrom were also inhibited by ginsenoside Rb1, Rb2, Rg1 and Re. These results suggest that ginsenoside Rbl, Hbs, Rgl and Re are the bioactive components of panax ginseng on the inhibition of the development of morphine tolerance and dependence, and the inhibition of abrupt abstinence sindrome. In addition, further research on the minor components of Pnnnxkinsenl should be investigated. A single or daily treatment with ginseng saponins did not induce any appreciable changes in the brain in level of monoamines at the variolls time intervals and at the various day intervals, respectively. The inhibitory or facilitated effects of ginseng saponins on electrically evoked contractions in guinea pig ileum ($\mu$-receptor) and mouse vats deferens ($\delta$-receptor) were not mediated through opioid receptors. The antagonism of a $\chi$ receptor agonist, U-50, 488H was also not mediated through opioid receptors in the animals treated with ginseng saponins, but mediated through serotonergic mechanisms. Ginseng saponins inhibited morphine 6-dehydrogenase which catalyzed the production of morphinone from morphine, and increased hepatic glutathione contents for the detoxication of morphinone. This result suggests that the dual action of the above plays an important role in the inhibition of the development of morphine tolerance and dependence.

  • Yang deficiency pattern is a representative syndrome differentiation. This article is a study on to which categories of modern diseases yang deficiency is assigned by reference to modern clinical papers and the meaning of yang deficiency interpreted with a perspective of Korean Medicine and a modern perspective. Yang deficiency, yang qi deficiency, lack of yang qi and yang qi debilitation are the words found in "Nei Ching" and yang qi can be interpreted as something to warm, drive and arouse. Zhangzhongjing considered recovery or loss of Yang as the key to life in "Shanghanlun". Danxi proposed "Yang being liable to hyperactivity, Yin being insufficient" and emphasized pathological ministerial fire of Yang exuberance rather than physiological ministerial fire of Yang deficiency. Zhangjingyue proposed "Yang not being in excess, Yin being often deficient" and understood growth and decline of yin qi are all led by yang qi and put emphasis on true yin in addition to yang qi. Diseases of yang deficiency pattern are related with decline of metabolic level, hypofunction of internal secretion, disorder of immune function, disorder of automatic nerve system, sympathetic nerve inhibition, metabolic disorder of microelements, increase of cGMP, change of microcirculation, low speed of blood stream, kidney malfunction. Diseases related with kidney are sterility, polycystic ovary syndrome, spinal stenosis, edema, renal failure, IgA nephropathy, erectile dysfunction, nephritis, prostatitis, benign prostatic hyperplasia, decrease of adrenal cortical hormone by nephrotic syndrome, myelodysplastic syndrome. Disease related with heart are heart failure, arrhythmia, cardiomyopathy, atherosclerosis heart disease, hypertension, hyperlipidemia, pulmonary heart disease. Diseases related with spleen are irritable bowel syndrome, ulcerative colitis. Diseases related with liver are hypothyroidism, liver cirrhosis ascites, hepatitis B, chronic hepatitis, hepatic diabetes. Diseases related with lung are allergic rhinitis, cough variant asthma, bronchial asthma, pulmonary emphysema. And diabetes mellitus, metabolic syndrome, aplastic anemia, headache, encephalatrophy, Alzheimer's disease are also related with yang deficiency.

  • Obstruction of the bile duct owing to the direct extension of a tumor is occasionally found in patients with a hepatic neoplasm, but bile duct tumor thrombus caused by the intrabiliary transplantation of a free-floating tumor is a rare complication of hepatocellular carcinoma A 50-year-old woman was diagnosed with HCC with bile duct tumor thrombi. She received transarterial chemoembolization (TACE) because her liver function was not suitable for surgery at the time of diagnosis. After TACE, infected biloma occurred recurrently. Thus, resection of the HCC, including the bile duct tumor thrombi, was performed. Six months after the surgery, recurred HCC in the distal common bile duct as drop metastasis was noted. The patient was treated with tomotherapy and has been alive for three years as of this writing, without recurrence. The prognosis of HCC with bile duct tumor thrombi is considered dismal, but if appropriate procedures are selected and are actively carried out, long-term survival can occasionally be achieved.
