Objectives : The purpose of this study was to investigate the effects of Angelicae Gigantis Radix Water Extract(AG) on the production of proinflammatory mediators in RAW 264.7 cells stimulated with lipopolysaccharide(LPS). Method : RAW 264.7 cells were cotreated with AG(50 and 100 ug/mL) and lipopolysaccharide(LPS; 1 ug/mL) for 24 hours. After 24 hour treatment, using Bead-based multiplex cytokine assay, concentrations of various cytokines such as interleukin(IL)-6, IL-$1{\beta}$, IL-10, tumor necrosis factor-alpha(TNF-${\alpha}$), granulocyte colony-stimulating factor(G-CSF), granulocyte macrophage colony-stimulating factor(GM-CSF), interferon inducible protein-10(IP-10), leukemia inhibitory factor(LIF), lipopolysaccharide-induced chemokine(LIX), monocyte chemoattractant protein-1(MCP-1), macrophage colony-stimulating factor(M-CSF), macrophage inflammatory protein(MIP)-$1{\alpha}$, MIP-$1{\beta}$, MIP-2, Regulated on Activation, Normal T cell Expressed and Secreted(RANTES) and vascular endothelial growth factor(VEGF) were measured. Result : AG significantly inhibited LPS-induced production of TNF-${\alpha}$, MIP-$1{\alpha}$, G-CSF, RANTES, IL-10, and M-CSF from LPS-stimulated RAW 264.7 cells at the concentrations of 50 and 100 ug/mL. AG significantly inhibited LPS-induced production of MIP-$1{\beta}$, MIP-2, GM-CSF, and IL-6 from LPS-stimulated RAW 264.7 cells at the concentrations of 50 ug/mL. AG significantly inhibited LPS-induced production of VEGF from LPS-stimulated RAW 264.7 cells at the concentrations of 100 ug/mL. But AG did not show any significant effect on the production of MCP-1, LIF, LIX, IP-10 and IL-$1{\beta}$ from LPS-induced RAW 264.7 cells. Conclusion : These results suggest that AG has anti-inflammatory effect related with its inhibition of proinflammatory mediators such as TNF-${\alpha}$, MIP-$1{\alpha}$, G-CSF, RANTES, IL-10, MIP-$1{\beta}$, MIP-2, GM-CSF, IL-6, VEGF and M-CSF in LPS-induced macrophages.

Objective : Angelica Gigas Nakai is a popular oriental medicine used for the treatment of vascular diseases. The aim of this study is to investigate neuroprotective effect of the water extract of Anelicae Gigantis Radix Palva (AG) in transient middle cerebral artery occlusion (tMCAO)-induced ischemic rats via the regulation of angiogenesis-related molecules. Methods : Sprague-Dawley rats were intraperitoneally administrated with AG water extract at doses of 10, 25, 50 mg/kg body weight after tMCAO (90 min occlusion). reperfusion for 24 hr infarction volumes were measured by 2,3,5-tetrazolium chloride (TTC) staining. Brain tissues were observed neuronal cell injuries by nissl staining, and also brain-blood barrier (BBB) permeability change by evans blue. Expression of vascular endothelial growth factor (VEGF), angiopoietin-1 (Ang-1) and Tie-2 receptor protein in brain tissues was determined by western blot. Results : AG water extract significantly reduced infarction volume in ischemic brains of rats, degradation of neuronal cell, BBB permeability and expression of VEGF protein dose-dependently. Ang-1 protein was increased dose-dependantly, not significantly. Conclusion : This study suggests that AG water extract shows neuroprotective effect by preventing BBB breakdown, with regulating angiogenesis factor VEGF and Ang-1.

Angelica gigantis (AG), Rehamaninae Radix(RR), Paenia japonica (PJ), and Polygoni multiflori Radix (PM) have been used as medicinal plants to tonify the blood. General function of the drugs have been known to nourish blood and control the heart and liver meridians. Recently, several studies have proposed mechanisms by which some oriental medicinal herbs work on the immune system. However, it is uncertain whether aqueous-extract of these drugs has immunomodulatory effect yet. In this study, I investigated the immune promotive effects of the water-extracted AG, RR, PJ and PM. The water-extracted AG, RR, PJ and PM inhibited NO production and iNOS expression in LPS stimulated RAW 264.7 macrophage cell line. Among these extracts, AG and PM induced expression of IL-2 and IFN${\gamma}$ in mouse spleen cells. In the flow cytometry analysis, PM-stimulated mouse spleen cells showed an increase in B-cell phenotype (CD45R/B220). The oral administration of Polygoni multiflori water-extracts to mice having S-180 abdominal dropsy cancer prolonged life-span more than control mice. These data suggest that among these extracts, PM has cellular and humoral immune-enhancement effect through IL-2 and IFN${\gamma}$ cytokine production, the regulation of NO production in macrophage cells and the B cell production in spleen cells.

Radix Angelicae Gigantis is sweet and pungent in flavor, warm in property. Its effects are tonifying the blood, promoting blood circulation, relieving pain and moistening the bowels. Its indications are blood deficiency syndrome characterized by sallow complexion, dizziness, irregular menstruation, amenorrhea, pains due to blood stasis, and rheumatic arthralgia. Using genes of A. gigas, A. acutiloba, and A. sinensis, the origin of which is identified, as criteria, we analysed many kinds of Angelica with RAPD and RFLP on ITS region, in order to compare and discriminate genes extracted from crude drugs ‘Dang-gui’, that are produced in Korea on the one hand and imported on the other hand. We reached the following conclusion. 1. We could extract DNA from both original plant and dried plant. 2. Especially Uniprimer #1, Uniprimer #2, Uniprimer #4 and Uniprimer ＃9 were useful. 3. Among the restriction enzymes Sma I, Msp I, Hae III, and Hinf I, used in this experiment, four restriction enzymes except Hinf I could be used properly in discriminating all samples used as A. gigas. We think that this result can be used as a method of discriminating crude drug of Angelica L. related drugs, and used in controlling quality and circulation.

Objectives: The purpose of the study is to assess both the approximate lethal dose and the single dose intramuscular injection toxicity of Danggui (Angelica gigantis radix) pharmacopuncture (DGP) in Sprague-Dawley (SD) rats. Methods: The experiments were conducted at the good laboratory practice (GLP) laboratory, Biotoxtech Co., which is a laboratory approved by the ministry of food and drug safety (MFDS). The study was performed according to the GLP regulation and the toxicity test guidelines of the MFDS (2009) after approval of the institutional animal care and use committee of Biotoxtech. Single doses of DGP were injected intramuscularly into the rats in three test groups of 6 week old SD rats (5 male and 5 female rats per groups) in the amounts of 0.1, 0.5, and 1.0 mL/animal for groups 2, 3, and 4, respectively, and normal saline solution in the amount of 1.0 mL/animal was injected intramuscularly into the rats (5 male and 5 female rats) in the control group. Observations of the general symptoms and weight measurements were performed during the 14 day observation period after the injection. Hematologic and serum biochemical examination, necropsy, and a local tolerance test at the injection site were done after the observation period. Results: No death was observed in three test groups (0.1, 0.5 and 1.0 mL/animal group). In addition, the injection of DGP had no effect on general symptoms, weights, hematologic and serum biochemical examination, and necropsy. The results from the local tolerance tests at injection site showed no treatment related effects in the SD rats. Conclusion: The results of single dose intramuscular injection of DGP suggest that the approximate lethal dose is above 1.0 mL/animal for both male and female SD rats and that intramuscular injection of DGP may be safe.

Objectives : Angelica Gigantis Radix is prescribed as the root of different Angelica species on the pharmacopoeia in Korea, Japan and China. Chemical components and their biological activities were also different according to their species. A study for the development of simple method to compare Angelica roots was needed. In order to classify them, the methods such as DNA sequencing analysis and taste sensor were applied to three Angelica species like Angelica gigas, Angelica acutiloba and Angelica sinensis. Methods : PCR amplification of intergenic transcribed spacer (ITS) region was performed using ITS1 and ITS4 primer from nine Angelica roots, and then nucleotide sequence was determined. Taste pattern of samples were measured using the taste-sensing system SA402B equipped with a sensing unit, which consists of artificial lipid membrane sensor probes of anionic bitterness, astringency, saltiness, umami, and cationic bitterness (C00, AE1, CT0, AAE, and AN0, respectively). Results : As a result of comparing the similarity of the ITS region sequences, A. sinensis was discriminated from the others (A. gigas and A. acutiloba). Equally this genetic result, A. gigas and A. acutiloba showed similar taste pattern as compared to A. sinensis. Sourness, bitterness, aftertaste of bitterness, astringency, and aftertaste of astringency of A. sinensis were significantly high as compared with A. gigas and A. acutiloba. In contrast, richness was significantly low. Conclusions : These taste pattern can be used as a way of comparison of Angelica species and this technic could be applied to establish a taste pattern marker for standardization of herbs in various purposes.

Objectives: The aim of this study was to review the research trends in the treatment of pharmacopuncture for vascular dementia in Traditional Chinese medicine. Methods: We searched for articles in the China National Knowledge Infrastructure (CNKI) database from January 2000 to August 2020. Results: Among the total 63 articles, 9 articles were selected. All studies were randomized controlled trial studies. The Diagnostic and Statistical Manual of Mental Disorders (DSM) was most frequently used as diagnostic criteria. Effective rate and Activity of Daily Living (ADL) were most commonly used as outcome measurements. Angelica gigantis Radix (當歸), Salvia miltiorrhiza Bunge (丹蔘), and Astragali Radix (黃芪) were the most commonly used ingredients in pharmacopuncture. Joksamni (ST36) and Sinsu (BL23) were the most commonly used acupoints for pharmacopuncture treatment. Based on the Risk of Bias (RoB) of these 9 articles, the overall quality of studies was low. Conclusions: Pharmacopuncture could be considered for the treatment of vascular dementia. In the future, various systematic studies on dementia are needed.
