  • Purpose: Menopausal syndrome is caused by urgent changes of sex hormone in women. The hormonal therapy can soothe the problems of menopausal patients, but it can increase the probability of another disease, such as breast cancer, heart attack, etc. So the demand of alternative herb therapy is increasing in Western countries. In Korea, herbal medicine is imported and used by Western doctors. To know and use the alternative herbal medicine, Korean Medical doctors should know their efficacy and safety. Methods: We researched the Medline(Pubmed) with the key word such as 'CAM', 'herb' and 'menopause'. We selected the herbs known as treating the menopausal syndrome and researched the similar or same herbs that are used in Korean medicine by the scientific name and efficient ingredients. To evaluate the efficacy of the herbs, we compared the herbs that were differently defined in alternative and Korean medicine Results: Balm, black cohosh, chaste berry, dong quai. evening primrose oil. ginkgo, St. John's wort, valerian root, and sarsaparilla were chosen as prevalent herbs used in alternative medicine. The pharmacologic effect of Black cohosh, licorice root, St. John's wort were recognized. But these three herbs are not usually prescripted for menopausal patients in Korean medicine. So we could apply these three herbs as one of Korean medical treatments. The efficacy of other herbs cannot be surely prescripted for menopausal patients. Conclusion: The efficacy and safety of alternative medicine is not proved yet. But to diversify the treatmental methods of Korean medicine, we need to prove and use these medicine as one of Korean medical treatment.

  • Herbal remedies are commonly used by patients worldwide. Because these herbal preparations share the same metabolic and transport proteins with prescribed medicines, the potential for a drug-herb interaction is substantial and is an issue of significant concern. This review paper summarizes drug-herb interactions involving inhibition or induction of cytochrome P450 enzymes, drug transporters as well as modulation of drug pharmacodynamics. An increasing number of in vitro and animal studies, case reports and clinical trials evaluating such interactions have been reported, and implications of these studies are discussed in this review. The most commonly implicated drugs in the interaction include anticoagulants, antiplatelets, immunosuppressants, anti-neoplastics, protease inhibitors, and some antidepressants. Pharmacokinetic and/or pharmacodynamic interactions of five commonly used herbal remedies (danshen, garlic, Ginkgo biloba, ginseng, and St John's wort) with these drugs are presented, with focus of discussion being the potentials for interaction, their mechanisms and clinical implications. There is a necessity for adequate pharmacovigilance to be carried out in minimizing unanticipated but often preventable drug-herb interactions.

  • Immune enhancing activities of water and ethanol extracts of Hypericum perforatum L. (HP) were examined. HP extracts inhibited the growth of human hepatocarcinoma, human gastric cancer cell and human breast cancer cells in concentration-dependent mammers over a concentration range of $0.05{\sim}1.0\;mg/ml$, showing inhibiton of more than 80% with the concentration of 1.0 mg/ml. However, HP the same concentration. Overall selectivity of the extracts on the three human cancer lines was over 3.5, which is higher than those from the conventional herbs. The growth of human immune B and T cells was enhanced up to 1.4 to 2.0 folds by the addition of the extracts for 4 days, compared to controls. Ethanol extracts of HP after 6 days incubation increased the secretions of tumor necrosis factor-alpha $(TNF-{\alpha})$ from T cells and interleukin-6 (IL-6) from B cells to 6.7 pg/cell and 6.8 pg/cell, respectively. These results suggest that HP has a potent immune enhancing effect.

  • Objectives : Depression disturbs the individual life from the loss of productivity to suicide. Furthermore the whole society is also influenced by depression in social and economic areas. Many scientific treatment methods are known to be effective in depression. But in reality more than half of patients with depression prefer self help treatment rather than medically based treatment. For the patients with mild depression and primary physicians, it is reasonable to provide the evidence based self care including self help or alternative treatment. This study is supported by the Korean Health 21 R&D Project for the Depression Center to establish the Korean treatment guideline for depression. Methods : The members of Depression Center including the authors attended the workshops where the methods of evidence based medicine such as literature search, quality evaluation of the articles, making the level of evidence were educated. The professional librarians helped the authors for get the searched articles. Among the total of 354 abstracts of systemic review and 300 abstracts of random controlled trials, 3 systemic reviews and 2 random controlled trials were the main structure of evaluation. Result : Among the 37 self care methods known to be effective for depression, 11 kinds of methods were worth of evaluation. The first step for the self care of mild depression is to use St. John's wort, exercise, bibliotherapy, and light therapy in depression during winter season. Acupuncture, negative ion therapy, massage, relaxation technique are known to be efective with evidence. Music therapy, hypnotherapy, and aromatherapy are known to be effective but until now the evidences is insufficient and further evaluations are needed. Conclusion : Among 11 listed self-care methods, several methods need more evidence especially in Korean situation. Exercise is the most recommendable evidence based self care method in Korea nowadays. St. John's wort is effective with evidence, but it is not the OTC drug in Korea, so it is not recommendable now. For the bibliotherapy, there is no book such as "Feeling Good" in Korea. Only the introductory book about depression is available. Publishing the self help book based upon cognitive behavioral approach or psychodynamic approach is needed. Light therapy is practiced in a few clinics, but not self-help style. Exposure to the sunlight is recommended in the level of commen sense. These self care methods are for the mild patient. Moderate to severe patients with depression should seek the professional treatment.

  • The genetic relationships of Hypericum erectum, H. ascyron and H. perforatum Thunb. by RAPD using total 46 primers were analysed 30 primers among primers tested showed the amplification band in all. The amplified DNA fragment ranged from 0.25 to 6.6 kb in size. The 411 bands (34.4%) among 1194 bands derived from 30 primers were polymorphic, and 13.7 bands per primer were observed. The phenograms for six analyzed individuals by RAPD markers were not matched well with those of the result by morphological characters. They were clustered monophyletic at the similarity coefficient value ranged from 0.24 to 0.96.

  • Methylglyoxal (MGO) is a highly reactive metabolite of glucose which is known to cause damage and induce apoptosis in endothelial cells. Endothelial cell damage is implicated in the progression of diabetes-associated complications and atherosclerosis. Hypericin, a naphthodianthrone isolated from Hypericum perforatum L. (St. John's Wort), is a potent and selective inhibitor of protein kinase C and is reported to reduce neuropathic pain. In this work, we investigated the protective effect of hypericin on MGO-induced apoptosis in human umbilical vein endothelial cells (HUVECs). Hypericin showed significant anti-apoptotic activity in MGO-treated HUVECs. Pretreatment with hypericin significantly inhibited MGO-induced changes in cell morphology, cell death, and production of intracellular reactive oxygen species. Hypericin prevented MGO-induced apoptosis in HUVECs by increasing Bcl-2 expression and decreasing Bax expression. MGO was found to activate mitogen-activated protein kinases (MAPKs). Pretreatment with hypericin strongly inhibited the activation of MAPKs, including P38, JNK, and ERK1/2. Interestingly, hypericin also inhibited the formation of AGEs. These findings suggest that hypericin may be an effective regulator of MGO-induced apoptosis. In conclusion, hypericin downregulated the formation of AGEs and ameliorated MGO-induced dysfunction in human endothelial cells.

  • Purpose: Many breastfeeding women have used complementary and alternative medicine, but the guideline for lactation does not exist on complementary medicine. This study is to investigate efficacy and safety of complementary and alternative medicine in breastfeeding. Methods: We searched for papers which had breastfeeding, complementary medicine, acupuncture and herb in the pubmed, scopus site and Korean journals. Results: 38 papers were found. Acupuncture could have the efficacy on hypogalatia and mastitis. Compound herb therapy had effect on hypogalactia, but none of herbs were investigated for safety all except for St John's wort. So more clinical trials about herbs would be needed. Massage and the other complementary therapies would be helpful for breastfeeding mother. Conclusion: Acupuncture could be a good treatment for hypogalactia and inflammation of the breast. For making guidelines on complementary and alternative medicine during lactation, more research will be needed.

  • Objectives : This study was undertaken to learn what should be considered in a good clinical trial investigating a herbal medicine as an antidepressant. Methods : Five well-designed clinical trials published from 2000 to 2006 investigating SJWE in depressive disorder were selected. The trials were reviewed and compared in terms of methodology such as trial design, patient selection, efficacy & safety evaluation, and so on. On the basis of this review of the trials and the regulations and guidelines of KFDA, we suggest some points to be considered for a good clinical trial of a herb for depression. Results : Although every trial had its own unique design, procedure, objectives and so on, all trials used randomizing and double blinding methods. If there is no ethical problem, a placebo-controlled design should be considered in a herbal antidepressant clinical trial for depression. Conclusions : Some points to be considered in an optimal & good clinical trial for an antidepressive herbal medicine were suggested as follows: 1) randomizing and double blinding manner is essential, 2) if there is no ethical problem, placebo control design should be considered, 3) the trial period should be 6 weeks, 4) out-patients will be recruited as subjects, 5) investigators will be well-trained psychiatrists or medical doctors, 6) the number of subjects should be calculated by statistical methods, 7) subjects should be diagnosed by DSM-IV criteria, 8) subjects who have current risk of committing suicide should be excluded, etc.
