In this study, Artemisia capillaris, which has been used in oriental medicine and folks remedy, was investigated to characterize the nutritional composition (protein, lipid, ash, fiber, amino acids, fatty acids, Na, K, P, Mg, Ca and Fe) and effective substance (scopoletin). Artemisia capillaris has often been cited in medical literature for its medicinal effects. The Korean Food and Drug Administration allowed Artemisia capillaris as a food stuff and indicated as In-Jin-Sook. From the view point of the subjects who eat In-Jin-Sook products, most of them ingested it for a certain pharmacological efficacy rather than as a beverage or a food. Therefore, we need to develop functional foods using In-Jin-Sook. Artemisia capillaris was superior in protein, crude fiber, amino acid and fatty acid compositions to wild greens according to Korean Nutritional Composition Table. Also scopoletin, blown for blood vessel relaxation and hypotensive effect, was detected at the level of 326.13 $\mu\textrm{g}$/g. These results demonstrated that Artemisia capillaris has both pharmaceutical effects and balanced nutritional contents. Artemisia capillaris has sufficient values to use as a food stuff for functional foods.

A major portion of drugs used in Ayurvedic system of medicine which has been practiced since the early human civilization in Indian subcontinent were of plant origin. It should be noted that 70% of the population in this region depends on Ayurveda for their medical treatment and 60% of the drug resources are obtained from the Himalayan region. Therefore, Nepal becomes a potential source of plant drug resource since it occupies a major portion of the Himalaya. In the present paper, in general a current status of medicinal plant resources of Himalayan region especially Nepal will be discussed. In addition to this, a typical example of antidiabetic activity of Shilajit will be taken for the discussion. Shilajit is one of the crucial elements in several formulations including those of Rasayana, a therapy in Ayurveda, which has been practiced in the prevention of ageing and mental disorder. Although, Shilajit is widely used for the treatment of diabetes, no satisfactory scientific reports are available up to now. The crude Shilajit in the market is a dark brown or black rock-like substance collected from the Himalayan region with a strong smell of cow's stale urine. In our studies, Shilajit (collected in the central Himalayan region) prevented the diabetes in nonobese diabetic (NOD) mice model. Shilajit also prevented the diabetes in the rats against the action of multiple low-dose (10 mg/kg, i.v., 5 times) of streptozotocin. On the other hand, Shilajit did not show antioxidative activity. The preventive action of Shilajit on diabetes is mainly focused on the Thl and Th2 cell activities, since Th2 cells activity was found to be significantly upregulated. Shilajit, however, showed a mild action in controlling the blood sugar level in young, old, and mild diabetic rats, but not in the severe diabetic rats. It also stimulated the nitric oxide production in macrophages. Based on these evidences, the antidiabetic activities of Shilajit appear to be immunomodulative probably by protecting or strengthening insulin-producing b-cells in the pancreas. Further systematic research on constituents of Shilajit and its quality evaluation is necessary to enable the use of natural medicines in the treatment of diabetes.

Comparative biological activities of 70fr methanol extracts from the main roots and rhizomes of both red and white ginsengs were investigated using several in vitro experimental models. The main root of red ginseng and the rhizome of white ginseng strongly inhibited lipld peroxidation of hepatic microsomes induced by the non-enzymatic $Fe^{+}$ / Ascorbate system. The main root and rhizome of red ginseng markedly inhibited the release of G07, GPT and LDH by $CCl_4$-induced cytotoxicity in primary cultured rat hepatocytes as compared with those of white ginseng. And also, the main root of red ginseng showed a slight differentiating activity on HL-60 cancer cell line. The results suggest that the rhizome of ginseng have potential as a source of medicinal crude drug with possible pharmacolobica1 applications .

This study has been undertaken to increase availability of native camellia in Jeonnam as a medicinal resource and to isolate the effective components from them. Multidrug resistance(MDR) by tumor cells is a major obstacle to successful cancer chemotherapy. We report that the crude extracts of camellia flowers, leaves has a chemosensitizing effect that can reverse Pgp-mediated MDR by increasing the intracellular accumulation of drugs. The cytotoxic and chemosensitizing effects of MeOH extract from 12 spp. citrus fruits on the AML-2/D100 were determined using MTT assay. Chemosensitizing effects was screened in the presence of vincristine, a good substrate of Pgp. IC$\sub$50/ for extracts in AML-2/WT was found to be 65∼350$\mu\textrm{g}$/$m\ell$ whereas the range of its mean IC$\sub$50/ value in Pgp-overexpressing cells (AML-2/Dl00) in the presence of vincristine was 90∼400$\mu\textrm{g}$/$m\ell$. Of the extracts tested, mature leaf extract displayed the most potent chemosensitizing effect［IC$\sub$50/;100 $\mu\textrm{g}$/$m\ell$, CR;1.06, RF;2.97 in the presence of VCR］. This indicates that the toxicity (IC$\sub$50/;288.89$\mu\textrm{g}$/$m\ell$) of mature leaf extract is minimal at concentrations required for a complete reversal of the drug resistance. Also, this result indicates that crude extracts of camellia mature leaves would contain some principles which have chemosensitizing activity.

토천궁은 개화는 되지만 종자 결실이 이루어지지 않아 주로 종근이나 뇌두에 의해 번식하므로 번식율이 매우 저조한 특성이 있다. 따라서 이의 원인을 구명하고자 자웅배우체 형성과정과 자가수분을 통한 수정현상을 보기 위하여 조사하였던 바 그 결과는 다음과 같다. 토천궁은 대소포자에서 감수분열이 정상적으로 이루어지고 배낭형성에서 난장치는 50% 정도가 정상적으로 이루어지고, 화분형성에서는 90%이상이 잘 이루어졌다. 토천궁의 배낭은 주심조직의 세포가 작아 모든 기관분열에서 관찰하기가 어려웠고 특히 토천궁은 배낭 형성체가 난장치로 발달되는 꽃은 거의 없었으며 화분립은 일부가 형성 되었다.

Immunosuppressors cyclosporine A(CsA) and tacrolimus(FK506), the primary cellular target of which is calcineurin/nuclear factor of activated T cells(NFAT) signalling pathways, decrease beta-cell insulin content and mRNA expression. The posttransplantation diabetes mellitus(PTDM) is a frequent complication in immunosuppressive therapy. The present study was to examine the effect of a crude water extracts of medicinal herbs such as Sanguisorba officinalis(SOE) on the immunosuppressive activity with lymphocyte and insulin secretion in insulinoma cell lines with RIN-5mF. It was found that SOE treatment had effect of immunosuppressor on lymphocytes and also significantly increased insulin secretion in RIN-5mF compared to other agents. we might suggest a mechanism on insulin secretion by HNF4a. Taken together, the present study suggested that SOE might serve as immunosuppressive drug in PTDM.

Overproduction of peroxynitrite ($ONOO^-$) causes a variety of disease such as atherosclerosis, hypercholesterolemia, diabetes mellitus or obesity. Peroxynitrite scavenging activities and HPLC analysis on the five Oriental medicinal drugs belonging to the genus Citrus, Aurantium or Poncirus (Rutaceae family) and HPLC analysis were taken to evaluate flavanone glycosides with peroxynitrite scavenging activity. The $IC_{50}s$ of the five crude drugs were shown as follows: Aurantii nobilis Pericarpium (Jinpi, 18.3 ${\mu}g$/ml), Citrii unshiu Pericarpium (Chungpi, 7.50${\mu}g$/ml), Citrii unshiu Semen (Gyulhaek, >50.0${\mu}g$/ml), Aurantii Fructus (Jigak, 18.3${\mu}g$/ml), and Poncirii Fructus (Jisil, >50.0${\mu}g$/ml) where Korean crude drug's names are noted in the parenthesis. Peroxynitrite scavenging effect of flavanones or their glycosides usually contained in Citrus species were observed as follows: hesperetin (1.89 ${\mu}g$/ml), naringenin (7.77 ${\mu}g$/ml), hesperidin (8.44 ${\mu}g$/ml), poncirin (>50.0 ${\mu}g$/ml)and ponciretin(>50.0 ${\mu}g$/ml). The activities of naringin and poncirin with ${\alpha}$-L-rhamnopyranosyl($1{\rightarrow}2$)-${\beta}$-D-glucopyranosyl moiety were weak. HPLC analytical data revealed that Jinpi (the peels of mature fruits of Citrus unshiu) and Chungpi (the peels of immature fruits of C. unshiu) had high quantities of hesperidin as the value of 142.1${\pm}$0.21 and 104.51${\pm}$1.10 mg/g dried weight, respectively. Poncirin was clearly detected in only Jisil and naringenin and naringin were not observed on the HPLC chromatogram of the five crude drugs.
