Bone is continuously remodeled by osteoblasts and osteoclasts. Osteoclasts play an important role in bone metabolism by resorbing the bone matrix. Thus, the compounds inhibiting osteoclasts can improve bone diseases such as osteoporosis. The methanol extracts of 159 herbal medicines were screened for the inhibitory activity against differentiation of osteoclasts. Among the tested extracts, Achuranthis Radix and Corydalis Tuber showed relatively strong inhibitory activity against differentiation of osteoclasts, whereas they have no significant effect on proliferation of osteoclasts.

Essential oils of various plants have been known for potential biological effects such as antibacterial, antifungal, spasmolytic, antiplasmodial activities and insect-repellent property. Recently, the essential oils have attracted considerable interest in oral disease therapy. This essential oil has been known as being effective on easing sick house syndrome, giving forest aroma therapy effect and acting as repellent against pest. The essential oil of Pinus koraiensi, a native plant from Hongcheon-gun, Gangwon-do, was obtained by hydrodistillation. In light of its medicinal importance, in this study its composition, antibacterial activity and the reducing effect of offensive odor have been analyzed. The composition of essential oil was determined by GC and GC-MS. We have identified 14 compounds, of which 1R-${\alpha}$-pinene (19.38 %), 3-carene (10.21 %), camphene (9.82 %), limonene (9.00 %), bicyclo[2,2,1] heptan-2-ol (8.76 %) and ${\beta}$-phellandrene (7.98 %) were the main components. Essential oils from P. koraiensis, Chamaecyparis obtusa, Abies holophylla and Pinus densiflora were compared in terms of alleviating effect of malodors caused from formaldehyde, ammonia, trimethylamine and methylmercaptan. P. koraiensis essential oil was found to decrease the amounts of ammonia and trimethylamine by 75.17 % and 77.36 %, respectively. Antibacterial activity against Streptococcus mutans and Streptococcus sobrinus, which were known as oral cavity inducer, was investigated using the paper disc agar diffusion method. The inhibition zone was observed against S. mutans (5.97 mm) and S. sobrinus (1.40 mm), respectively. P. koraiensis essential oil shown effective deodorization and inhibitory activity against oral cavity in this study might be potential material in oral sanitary industry.

The Clinical Study on the Body Weight Loss of Taeumin Inpatients in Stroke by Sasang Constitutional Medicinal Treatment. Purpose: It has been frequently noted that overweight and obesity have a stronger relationship to hypertension and diabetes mellitus than to the risk of stroke. The purpose of this study is to find out whether Sasang Constitutional Medicinal treatment in the stroke patients of Tae-um-in has an effect on local or general weight loss. Methods: Case-control study was applied. The experiment group is the 24 Taeumin stroke inpatients who were in hospital in Kyung-Hee Oriental Hospital from July 1, 2000 to October 1 and received Sasang Constitutional Medicinal treatment. The control group is the 13 Taeumin stroke inpatients who were in the hospital during the same period but didn't receive Sasang Constitutional Medicinal treatment. In the two groups, body weight, BMI, the skin fold(cm) of triceps, suprailiac, abdominal portion, and thigh and the circumference(cm) of wrist, biceps, triceps, and W/H ratio were compared and studied for three weeks. Results: 1. In the experiment group, there were 8 women and 15 men, 23 in total and in the control group, there were 5 women and 9 men, 14 in total. 2. From two weeks later, there was a significant decrease in the experiment group in weight loss, the ratio of loss, and BMI(p<0.05). 3. Concerned with the change in the skin fold of suprailiac portion, there was a significant decrease in each group(p<0.05). 4. Concerned with the change in the skin fold of Chunchu-Hyel portion(天樞穴), thigh and in the circumference of hip, W/H ratio, there was a significant decrease in the experiment group(p<0.05). 5. Concerned with the change in the value of Lipid Profile, GOT, and GPT, only Glucose(GLU) showed a significant decrease(p<0.05) in the experiment group(p<0.05). As Conclusion, Sasang Constitutional Medicinal treatment in the stroke patients of Tae-um-in has an effect on local or general weight loss.

This study was performed to observe the effect of hot-water extracts from garlic and 13 kinds of medicinal plants composites (GMP) on hyperlipidemia and hepatoprotective activity in rats administered with alcohol. Male Sprague-Dawly rats were fed an AIN-93 diet (Normal), a normal diet plus ethanol (control, 10 ml of 40% ethanoljkgjday), a control diet plus 0.5% garlic and 1.0% medicinal plants composites extracts (GMP-I), and a control diet plus 1.0% garlic and medicinal plants composites extracts (GMP-II) for 7 days. Blood glucose was higher than the control, but it was markedly decreased in the GMP-II group. Elevation total lipids, cholesterol, triglyceride and phospholipids in serum were markedly decreased in rats fed with GMP-I. GMP-II also inhibited the increase of lipid content in serum. Activities of GOT, GPT, $\gamma$-GTP and ALP in serum elevated by alcohol were significantly inhibited in the GMP group. TBARS content of serum was significantly decreased in GMP groups administered with garlic and medicinal plant extracts. Extracts of garlic and medicinal plants play an important role in recovering liver function in rats from alcohol induced damage.

This study was performed to provide basic ideas as understanding and application for oriental medicinal cuisine (Yak-Sun). To develop medicinal cuisine, it is necessary to grasp the theoretical system. And to develop medicinal cuisine for health enhancement, it is also required not only to consider constitutions but also to suggest the need of knowledge for moderation in terms of regimen along with the theory of oriental medicine. Also to develop medicinal cuisine according to the perspective of oriental medicinal theory, what should be taken into account is not only the understanding of the characteristics of food materials, but also the properties of them that the theory of oriental medicine. Lastly the scientific effect of the medicinal cuisine which is developed according to the oriental medicinal theory. And it is believed to De essential for the government to make effects to set a standard and laws to validate the medicinal effects and the process of assessment so that the systematic development can be encouraged, and to prepare guidance to food development for national health improvement. This research was planned and executed to evaluate how the composition of Yak-sun(oriental diet therapy) can effect health conditions of people who are suffering from diet-related diseases like cardiovascular related disease. by taking Yak-sun in a form of nutritional supplement with our daily meals. We produced Yak-sun tea with Mansam, Hwanggi, Tanggi and Paekchak and observed nutritional composition. We concluded that we could apply the components not only in a form of tea, but also in other forms of various food. The information we received from this conclusion will be a basic information on how we can apply oriental medicinal resources into other food and will also be a steppingstone for medicinal herbs to step foot in the field of functional food research, which already draws sizable attention world-wide.

The effects of Helicobacter pylori and medicinal plants extract (Leweifang) on the viability and interleukin(IL)-8 production of gastric epithelial cell were investigated. Cells viability was significantly decreased when they incubated with H. pylori or H. pylori toxin. Co-incubation with Leweifang increased H. pylori or H. pylori toxin-inhibited cell growth in a concentration-dependent manner. The production of IL-8 was greatly increased in H. pylori-infected KATO III gastric epithelial cells in a concentration- and time-dependent manner. The increased production of IL-8 was significantly inhibited by Leweifang $(1,000{\sim}5,000{\mu}g/ml)$. These results indicate that Leweifang has protective effect on H. pylori-inhibited cell growth and H. pylori-induced gastric mucosal cell inflammation by suppressing the production of inflammatory cytokine (IL-8) from gastric epithelial cells.

This experiment was conducted to test the control effect of methanol extracts of 10 medicinal plants on apple storage diseases caused by Botryosphaeria berengeriana, Glomerella cingulata and Penicillium expansum. Out of the 10 medicinal plants, methanol extracts of Coptis japonica and Anemarrhena asphodeloides inhibited effectively the mycelial growth of B. berengeriana, G. cingulata and P. expansum in vitro, for which the inhibition ratios of the two plant extracts were 100.0% and 89.3%, 73.7% and 94.1%, and 100.0% and 51.6%, respectively. Spore germination of the three fungi was inhibited 100% only by C. japonica extract, but only P. expansum was inhibited 100% by A. asphodeloides extract. No lesion was formed y the fungi at 5$^{\circ}C$ up to 2 weeks after inoculation. Lesion sizes produced by the three fungi at the temperature ranges of 1$0^{\circ}C$ to $25^{\circ}C$ and infection of B. berengeriana and G. cingulata were inhibited by C. japonica extract, but not by A. asphodeloides extract, while no lesion was formed by the fungi at 5$^{\circ}C$. Infections of the fungi on apples were somewhat stimulated by A. asphodeloides extract.
