Analysis of random amplified polymorphic DNAs(RAPDs) and internal morphological features were performed using three species of medicinal plants in the genus of Angelica(A. gigas Nakai, A. sinensis(Oliv.) Diels., A. acutiloba Kitagawa) to distinguish between these three species. Fifty decarmer oligonucleotide primers were screened for the RAPDs of the herbal plant species. Five primers generated distinct RAPD markers specific to the species of Angelica, In analysis of the degree of similarity, A. sinensis(Oliv.) Diels is more closely related to A. acutiloba Kitagawa than to A. gigas Nakai. Furthermore, we proved the usefulness of RAPD analysis for the discrimination of the species using dry roots and commercial plant materials. In internal morphology of three species, A. sinensis(Oliv.) Diels seemed to be more specialized in systemic than A. acutiloba Kitagawa and A. gigas Nakai

This study was designed to identify and characterize the mechanism of macrophage activation by AAP, an acidic polysaccharide fraction isolated from the roots of Angelica sinensis (Oliv.) Diels. As a result, AAP significantly enhanced nitric oxide (NO) production and cellular lysosomal enzyme activity in murine peritoneal macrophages in vitro and in vivo. Furthermore, L-NAME, a specific inhibitor of inducible nitric oxide synthase (iNOS), effectively suppressed AAP-induced NO generation in macrophages, indicating that AAP stimulated macrophages to produce NO through the induction of iNOS gene expression and the result was further confirmed by the experiment of the increase of AAP-induced iNOS transcription in a dose-dependent manner. To further investigate, AAP was shown to strongly augment toll-like receptor 4 (TLR4) mRNA expression and the pretreatment of macrophages with anti-TLR4 antibody significantly blocked AAP-induced NO release and the increase of iNOS activity, and tumor necrosis factor-$\alpha$ (TNF-$\alpha$) secretion.

The purpose of the present study is a comparison of the antioxidant effects of Angelica gigas Korea (AG), Angelica sinensis of China (AS), and Angelica acutiloba of Japan (AA), and comparison of the effects of AG, AS and AA on tight-junction related genes in human keratinocyte HaCaT cells. All species showed a strong antioxidant effect, and AA was higher than AG and AS in antioxidant effects. The cytotoxicity was confirmed to be higher in AS than AG and AA at a concentration of $1,600{\mu}g/ml$ using the MTS assay in HaCaT cells. We analyzed the effects of AG, AS, and AA on mRNA expression levels of various tight-junction related genes in HaCaT cells. We found that no obvious changes in expression of Claudin 1, 3, 4, 6, 7, 8, Occludin, JAM-A, ZO-1, ZO-2, and tricellulin by treatment of all species, suggesting that there is less possibility of side effects and skin moisturizing effects due to changes in tight-junction gene expression. Our results suggest that AG, AS, and AA are thought to be effective in reducing the oxidative stress of the skin and preventing the aging of the skin.

Background: In the herbal medicinal industry, Angelica gigas Nakai, Angelica sinensis (Oliv.) Diels. and Angelica acutiloba (Siebold & Zucc.) Kitag. are often confused, because the roots of the three species can not be distinguished by their appearance. This confusion can cause serious side effects. In this study, we determined the origins of Angelica roots distributed in the Korean market using the simple sequence repeat (SSR) markers developed based on the A. gigas chloroplast DNA sequence. Methods and Results: We collected twenty seven A. gigas and three A. acutiloba samples from the Seoul, Daegu, and Cheongju herbal medicinal markets. Fifty sections of one collection were mixed and ground to make a powder, which was used for DNA extraction using the cetyl trimethylammonium bromide (CTAB) method. Chloroplast based SSR markers were applied to the DNA for the determination of the species. In addition, polymorphism was found in eight samples. The phylogenetic analysis showed that the A. gigas roots collected from herbal medicinal markets were clearly discriminated from A. sinensis and A. acutiloba even though they were grouped into four clusters. Conclusions: This study showed that chloroplast based SSR markers would help the discrimination of Angelica roots in the Korean herbal medicinal industry and the markers are useful to prevent confusion between Angelica roots.

For discrimination the origins and the commercial herb medicines of three Angelicae Radixes (Danggui), anatomical characters of leaves, petioles, and root cross-section were investigated and those were compared each other. The key for discrimination of these herb medicines was made by below simple characters: development of periderm, absent and present of collenchyma under the periderm, and distribution of latex tube in cortex. The result of discrimination for the commercial herb medicines based on the discrimination key, Angelicae gjgantis Radix (Angelica Gigas Root), Angelicae Radix (Japanese Angelica Root), and Radix Angelicae Sinensis (Danggui) were correctly identified for Angelica gigas Nakai, A acutiloba Kitagawa, and Angelica sinensis (Oliv.) Diels., respectively. Consequently, anatomical characters could be utilized for useful method to discriminate three Angelicae Radixes (Danggui).

The dried root of Angelica species is used in traditional Chinese medicine in East Asia, particularly in Korea, China and Japan. Since the plant origin differs in these countries, they are often misused or adulterated in the commercial markets, resulting in distrust among the consumers. Enormous efforts have therefore been focused to distinguish the origin for the Angelica genus, by using morphological or cytogenetical analyses, and chemical markers based on biochemical analyses of secondary metabolites. DNA is considerably stable against different cultivation conditions, and to treatment and processing after harvesting of plants. Hence, several researches have been filed for the development of molecular markers, based on the single nucleotide polymorphisms in specific regions of DNA. However, there are several obstacles for application in the commercial markets, concerning the reproducibility, accuracy, sensitivity, and rapidity of these tests. In this review, we summarize the research achievements that help classify the origin of Angelica species, in particular, Angelica gigas Nakai. A. sinensis(oliv.) Diels, A. acutiloba Kitag., and A. acutiloba var. sugiyamae Hikino. Further researches are required for practical applications.

We tried to analyze the inflammation reactions by treatment of AG, AS and AA in murine RAW 264.7 cells. To investigate the effect of AG, AS and AA on cell viability of RAW 264.7 cells, AG, AS and AA were treated for 24 h and MTS assay was performed. Cell viabilities were increased in $1,600{\mu}g/ml$ concentration by AS, AA and AG treatments, respectively. The mRNA expression levels of $IL-1{\beta}$, $TNF-{\alpha}$ and iNOS were increased by AG and AA treatment at a concentration of $200{\mu}g/ml$ in RAW 264.7 cells without Lipopolysaccharide (LPS) treatment. The mRNA expression levels of $IL-1{\beta}$, $TNF-{\alpha}$ and iNOS were increased by AG and AA 6 h treatment at a concentration of $200{\mu}g/ml$ with LPS treatment. In this study, we observed that AG, AS and AA show various activities on inflammation reaction depend on their treatment time. In the future, studies should be conducted to investigate the effects of AG, AS and AA on the various inflammatory responses of macrophages.

According to the Leukemia and Lymphoma Society, leukemia is a malignant disease (cancer) that originates in a cell in the marrow. It is characterized by the uncontrolled growth of developing marrow cells. There are two major classifications of leukemia: myelogenous or lymphocytic, which can each be acute or chronic. The terms myelogenous or lymphocytic denote the cell type involved. Thus, four major types of leukemia are: acute or chronic myelogenous leukemia and acute or chronic lymphocytic leukemia. Leukemia, lymphoma and myeloma are considered to be related cancers because they involve the uncontrolled growth of cells with similar functions and origins. The diseases result from an acquired (not inherited) genetic injury to the DNA of a single cell, which becomes abnormal (malignant) and multiplies continuously. In the United States, about 2,000 children and 27,000 adults are diagnosed each year with leukemia. Treatment for cancer may include one or more of the following: chemotherapy, radiation therapy, biological therapy, surgery and bone marrow transplantation. The most effective treatment for leukemia is chemotherapy, which may involve one or a combination of anticancer drugs that destroy cancer cells. Specific types of leukemia are sometimes treated with radiation therapy or biological therapy. Common side effects of most chemotherapy drugs include hair loss, nausea and vomiting, decreased blood counts and infections. Each type of leukemia is sensitive to different combinations of chemotherapy. Medications and length of treatment vary from person to person. Treatment time is usually from one to two years. During this time, your care is managed on an outpatient basis at M. D. Anderson Cancer Center or through your local doctor. Once your protocol is determined, you will receive more specific information about the drug(s) that Will be used to treat your leukemia. There are many factors that will determine the course of treatment, including age, general health, the specific type of leukemia, and also whether there has been previous treatment. there is considerable interest among basic and clinical researchers in novel drugs with activity against leukemia. the vast history of experience of traditional oriental medicine with medicinal plants may facilitate the identification of novel anti leukemic compounds. In the present investigation, we studied 31 kinds of anti leukemic medicinal plants, which its pharmacological action was already reported through many experimental articles and oriental medical book: 『pharmacological action and application of anticancer traditional chinese medicine』 In summary: Used leukemia cellline are HL60, HL-60, Jurkat, Molt-4 of human, and P388, L-1210, L615, L-210, EL-4 of mouse. 31 kinds of anti leukemic medicinal plants are Panax ginseng C.A Mey; Polygonum cuspidatum Sieb. et Zucc; Daphne genkwa Sieb. et Zucc; Aloe ferox Mill; Phorboc diester; Tripterygium wilfordii Hook .f.; Lycoris radiata (L Her)Herb; Atractylodes macrocephala Koidz; Lilium brownii F.E.
