A new herbal composition. HemoHIM, was developed using irradiated animal models and was successfully applied as an immune-improving agent. In a view that the protection and recovery of immune, hematopoietic and self-renewal tissues are essential for radioprotective agents, HemoHIM was developed based on a novel combination of three edible herbs (Angelica Radix, Cnidii Rhizoma. Paeonin Radix) that meet all those requirements. HemoHIM significantly protected the immune and hematopoietic system and enhanced their recovery in y-irradiated mice. For the application of HemoHIM as a health functional food and a supplementary agent for the cancer patients, the efficacy of HemoHIM to improve the immune functions was further evaluated in immune-depressed animals and humans. Animal studies demonstrated that HemoHIM significantly improved the immune functions in cyclophosphamide-treated mice, aged mice, and dexamethasone-treated mice. In human studies, HemoHIM enhanced the immune activity and cytokine secretion in sub-healthy volunteers, and alleviated the severe leukocyre depression in cancer patients during radiation and chemotherapy. Based on these results, HemoHIM was approved by Korea FDA as a material of health functional food for immune function improvement and will be commercially available soon. This case of HemoHIM research and development suggested that irradiated animals can be good models for biological degenerations such as immune depression, self-renewal tissue damage, and aging for the development of biological modulators.

This research evaluated how the composition of Yak-sun(oriental diet therapy), taken as a nutritional supplement with daily meals, can effect the medical condition of those suffering from modern diseases like obesity and hyperlipideia. We produced Yak-sun tea, determined its nutrient composition and physical characteristics and evaluated how this tea effects affects the active oxygen concentration inside the body by clinical practices. The study results indicated that this tea significantly decrease active oxygen concentration. We think that scientific and objective evaluation was done on the components of Yak-sun tea prescription. We concluded that we could apply the components not only in the form of tea, but also in other food forms. The information we received from this conclusion will provide basic information for the application of oriental medicinal resources into other foods and will also be a steppingstone in the field of functional food research for the development of medicinal herbs which is already an important research field world-wide.

It was demonstrated that Gangjihwan (DF), which is the herbal composition composed of Ephedra intermedia, Lithospermum erythrorhizon, and Rheum palmatum, inhibits obesity and hepatic steatosis in high fat diet (HFD)-fed obese mice. The aim of this study was to determine the effects of DF on visceral obesity, hepatic inflammation and fibrosis and the mechanism of actions involved in this process using in vivo and in vitro approaches. DF was extracted with water (DF-FW), 30% grain alcohol (DF-GA30), and 70% grain alcohol (DF-GA70). Administration of DF to HFD-fed control mice decreased visceral tissue mass and visceral adipocyte size without adverse effects. Visceral fat mass was decreased by DF-GA30 and DF-GA70, and visceral adipocyte size by all three DF extracts compared with obese control mice. Histological analysis revealed that three kinds of DF extracts reduced toluidine blue-stained mast cells and collagen accumulation in the liver, the extents of which were most eminent in DF-GA70-treated mice. DF-GA70 decreased the mRNA levels of the inflammation ($TNF{\alpha}$ and VCAM-1), fibrosis (${\alpha}-SMA$), and apoptosis (caspase 3) genes, but increasing the anti-apoptosis gene (Bcl-2) mRNA levels in the liver of obese control mice. Consistent with the in vivo data, GA-70 also altered the expression of inflammation genes ($TNF{\alpha}$ and MCP-1) in HepG2 cells. These results indicate that DF not only inhibits visceral obesity, but also ameliorates visceral obesity-induced hepatic inflammation and fibrosis and that this process may be mediated by regulating the hepatic expression of inflammatory and fibrogenic genes.

Major separation for the active ingredients and characterization of chemical properties in conjunction with screening test on animal were performed in order to analyze and standardize Ligustici Rhizoma or Angelicae Tenuissimae Radix as an important oriental herbal medicine for antiphlogistic or an important oriental herbal medicine for antiphlogistic or an anodyne. Furthermore the structure, composition and contents of ingredients for essential oil in Angelicae Tenuissimae Radix(Suckpo, Korea) were determined by means of Ge/MS followed by screening test on Z-ligustilide(82%) known as major ingredient as well as butylidenephthalide collected by HPLC with normal phase semiprep-column. The total active ingredient in Ligustici Rhizoma from China or Angelicae Tenuissimae harvested at Choonyang(Kyungnam, Korea), Jungsun(Kangwon, Korea), Suckpo(Kyungnam Korea), Youngchun(Kyungnam, Korea) have been determined showing higher abundant for three times on the product in Korea compared to that in China. In addition, the major component in Ahgelicae Tebyussunae Radux extract was found to be Z-ligustilide(70-80%) which is very different from that in Ligustici Rhizoma senkyunolide(39%) as major species. For screening test of Ligustici Rhizoma or Angelicae Tenuissimae Radix extracts toward the target animal, the efficiency has been shown the similarity on both extracts. Taking into account the level of ingredient, the total efficiency may be three times higher on Angelicae Tenuissimae Radix in Korea compared to Ligustici Rhizoma in China. As a result of present study, it is preferable to distinguish between Ligustici Rhizoma and Angelicae Tenuissimae Radix for better usage of oriental herbal medicine because of very different composition and abundant in spite of their similar screening effect.

This study was designed to analyze the chemical composition of essential oil in 'Shiranuhi' immature fruit and to test their biological activities. 'Shiranuhi' immature essential oils (SIEO) were obtained by steam distillation from fruits collected from Jeju Island and were analyzed using gas chromatograph (GC)-flame ionization detectors (FID) and GC-MS. Fourteen components were identified in the essential oil. Limonene (75.21%) and terpineol (8.68%) were the major components in SIEO. Since acne vulgaris is the combined result of a bacterial infection and the inflammatory response to that infection, we examined whether SIEO possessed antibacterial against skin pathogens. As a result, SIEO showed excellent antibacterial activities against drug-susceptible and -resistant Propionibacterium acnes and Staphylococcus epidermidis, which are acne-causing bacteria. In this study, SIEO was examined on DPPH radical scavenging activities, which showed moderate antioxidant activity ($SC_{50}$, $15.36{\mu}L/mL$). In order to determined whether SIEO can be safely applied to human skin, the cytotoxicity effects of SIEO were determined by colorimetric MTT assays in normal human fibroblasts and keratinocyte HaCaT cells. They exhibited low cytotoxicity at $0.5{\mu}L/mL$ in both celllines. Based on these results, we suggest the possibility that essential oil of 'Shiranuhi' maybe considered as an antibacterial and antioxidant agent.

This double-blind controlled clinical and microbiological study was carried out to determine the effects of mouthwash preparation containing the mixture of herbal extract on developing plaque and gingivitis in the experimental gingivitis model. Following a 2-week normalization period, 34 dental students were distributed randomly into 1 of 3 treatment groups. They rinsed, under supervision, two times daily for 3 weeks with either normal saline(CT), 0.1% chlorhexidine(CH), or the mixture of herbal extract (HT), but refrained from any oral hygiene measures. The Plaque Index(PlI), the Gingival Index(GI), and the amount of Gingival Crevicular Fluid(GCF) were measured at week 0,1,2, and 3 of the experimental period, while the assessment of total wet weight of plaque and the phase contrast microscopic examination of plaque were performed at the end of experimental period(3 weeks). Subjects using mouthrinse preparation containing the mixture of herbal extract demonstrated negligible, if any, changes in the accumulation and microbial composition of plaque compared to those using normal saline, while the reduction of gingival inflammation by this mixture was highly significant and comparable to that of chlorhexidine. The results of this study indicate that the preparation containing the mixture of herbal extract do not provide any antiplaque benefits but is very effective in inhibiting the development of and in reducing existing experimental gingivitis when used as mouthrinse. Further research is needed to determine whether a significant reduction of gingival inflammation without a concomitant decrease in plaque accumulation is of clinical importance.
