Objectives: This study aimed to review the general features of drug induced liver injury (DILI) and the important factors in consideration of herbal drugs and DILI. Methods: We reviewed general aspects of DILI such as classification, inducible factors, diagnosis methods, prevention, and the status of herbal drug-associated DILI via literature. Results: Besides the drug itself, genetic and environmental factors affect hepatic toxicity. There is a lack of definitive diagnoses of DILI by drugs, including herbal remedies. The possibility of herbal drug-associated DILI is exaggerated, and majority of herbal drug-derived hepatic injury could be easily prevented if Oriental doctors pay attention to this issue. Conclusion: This study can provide Oriental doctors an overview and be helpful in minimizing the episodes of hepatotoxicity in use of herbal drugs.

In this study, 49 Korean herbal medicines have been investigated with an in vitro evaluation system using glycation end products (AGEs) formation inhibitory activity. Of these, 18 herbal medicines ($IC_{50}$ < $50{\mu}g/ml$) were found to have significant AGEs formation inhibitory activity. Of these, five herbal medicines ($IC_{50}$ < $50{\mu}g/ml$) were found to have significant AGEs formation inhibitory activity. Particularly, Mallotus japonicus (twigs and leaves), Rhus javanica (twigs and leaves), Boehmeria nivea (whole plants), Quercus acuta (stems), and Eurya japonica (stems) showed more potent inhibitory activity (approximately 9-37 fold) than the positive control aminoguanidine ($IC_{50}=76.47{\mu}g/ml$).

Objective : In this study, we searched the experimental research about combined treatment of anticancer drug and herbal medicine for killing or inhibiting proliferation of Cancer cells searched in OASIS and KISS. This study aimed to analyze the experimental research paper about anticancer drug combined treatment with herbal medicine. Methods : We collected the research paper including killing or inhibiting proliferation of Cancer cells in OASIS and KISS using keyword anticancer drug with herbal medicine, tumor suppressor with herbal medicine, inhibition of Cancer with herbal medicine and combined treatment with herbal medicine. Assorting by cancer cells, we analyzed experimental results cancer cell viability, anticancer drug dosage, tumor weight and survival rate. Also, we checked the effects of herbal medicine on cancer and additive effect reducing side effect of anticancer drug. Results : Total 45 studies were selected. 38 studies reported combined treatment of anticancer drug and herbal medicine was more effective than only anticancer drug. The death of cancer cells was synergistically induced by the cotreatment of anticancer drug and herb extracts. The studies suggest that the cotreatment of anticancer drug and herb extracts could reduce side effect of anticancer drug. In addition, some studies reported cotreatment mechanism like apoptotic death signal processes. In combined treatment of anticancer drug and herb extracts, The expression of Fas/Fas L, Bax, Bcl2, Caspase-3 etc.. was markedly increased in cancer cells. Conclusions : Our results suggest that anticancer drug combined treatment with herbal medicine could be efficient for killing or inhibiting proliferation of cancer cells. However, this paper had some limitation as follows: First, collected studies have been published only for korean journal. Second, results of research and effects of combined treatment are not collected objectively. To solve these problems, more objective and balanced studies should be performed.

Objectives : The purpose of this study is to find a reasonable solution to a current status of drug classification between the drugs of western conventional (allopathic) medicine and Korean medicine. A clear and distinct concept on the drugs of allopathic medicine and Korean medicine based on reasonable concepts and broad consensus is a pressing issue in Korea, and will facilitate the development of herbal medicinal products and pharmaceutical industry. Methods : Considering the issue of drug classification from domestic and international regulations, we reviewed the current Drug Law of Korea and China, Guidance for Industry, Botanical Drug Products of USA, Directive 2004/24/EC of the European parliament and of the council. Results : In Korea, the drug classification of allopathic medicine and Korean medicine is quite vague even though differential licensure system is enforced for the clinicians of allopathic medicine and Korean medicine field. According to the definition in the Drug Law, the scope of Korean medicine drug is so broad that even a drug made of single-compound material, as well as herbal extract of crude mixture, is regarded as a drug of Korean medicine, as long as the material may be separated from medicinal herbs, animal tissues, or mineral resources. Only new compound not found in natural resources are outside of the scope of Korean medicine drug. In USA and EU, medicinal products manufactured from herbs are approved by separate regulations for the herbs with special waivers. In China, the category of new medicine and the definition of allopathic medicine and traditional chinese medicine are clearly specified and classified. Conclusions : As medicines are validated therapeutic materials for efficacy and toxicity, we suggest that generally the concept of conventional medicines is based on a single compound that has been synthesized and individually validated and that of Korean medicines is based on a compound extracted from natural materials or a complex of compounds that has been validated as a whole in its totality.

Licorice(Glycyrrhizae Radix et Rhizoma) is recorded as the root of Glycyrrhiza uralensis Fischer or Glycyrrhiza glabra Linne or Glycyrrhiza inflata Bat.(Leguminosae) in Korean Pharmacopoeia $9^{th}$ edition (KP9) and Chinese Pharmacopoeia 2005(CP2005), Glycyrrhiza uralensis Fischer or Glycyrrhiza glabra Linne in Japanese Pharmacopoeia 2005(JP2005). It is established the content standard of Glycyrrhizin 2.5 % and liquiritin 1% in KP9 and CP2005. But, according to the reports, all Licorice species were not sufficient for content standard of liquiritin 1.0% for licorice in KP9 and CP2005. It shows different content of liquiritin among G. uralensis, G. glabra and G. inflata. Also, it was reported liquiritin, liquiritin apioside are transformed into liquiritigenin by human internal flora. Therefore, we have studied for the pre-treatment condition and analytical method of liquiritigenin; It was good efficinet in 2M HCl reflux(1 hr) for hydrolysis and in methylene chloride for solvent fractionation. And 1% acetic acid in DW(A) and acetonitrile(B) with gradient condition as a mobile phase was most effective in HPLC analytical condition. According to these experimental methods, we have anlayzed content of liquiritigenin about 77 Licorice sample. In this research, it was also examined the content of liquiritin and liquiritigenin for Glycyrrhizae Radix related growing area. According to the results, we suggested the content standard of glycyrrhizin more than 2.5%, liquiritigenin more than 0.7%(after hydrolysis) of licorice.
