  • Objectives : Agrimoniae Herba is a herbal medicine widely distributed in Asia and contains flavonoids including catechin, quercitrin, rutin, hyperoside, and quercetin. This study aimed to investigate the anti-oxidant activity and skin barrier function of different solvent fractions (Hexane; methylene chloride, MC; ethyl acetate, EA; n-butanol, Bu; Water) obtained from Agrimoniae Herba. Methods : Anti-oxidant activity of different solvent fractions obtained from Agrimoniae Herba was investigated through total polyphenol contents, total flavonoid contents, 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity, and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activity measurements. Then, filament aggregating protein (Filaggrin), Type I collagen, ceramide synthase (CERS) 3, and CERS4 were analyzed to evaluate the skin barrier strengthening effect of different solvent fractions obtained from Agrimoniae Herba on UVB-stimulated HaCaT cells. Results : As a result of measuring total polyphenol contents, total flavonoid contents, DPPH free radical scavenging activity, and ABTS radical scavenging activity, antioxidant activity was found to be excellent in the order of EA > Bu > MC > Hexane > Water. As a result of measuring mRNA gene expression of Type I collagen, Filaggrin, CERS3, and CERS4 after UVB-stimulated was applied to HaCaT cells treated with different solvent fractions obtained from Agrimoniae Herba, it was found to increase significantly in the Bu-treated group. Conclusion : Our findings show that the Bu sample obtained from Agrimoniae Herba has excellent anti-oxidant ability, which increases Type I collagen, Filaggrin, and ceramide synthetase in UVB-stimulated HaCaT cells to control the skin barrier improvement effect.

  • Objects : This study was performed in order to evaluate the effects of Agrimoniae herba (AH) ethanol extract on intrastriatal hemorrhage (ISH). Method : ISH was induced by the stereotaxic intrastriatal injection of bacterial collagenase type IV in Sprague-Dawley rats. AH was orally given once a day for 3 days after ISH. Hematoma volume and percentage edema were examined. Immunohistochemistry was processed for iNOS, c-Fos, MMP-9, and MMP-12 expressions in the brain sections and each immuno-labeling were calculated with image analysis. Results : results are as follows; 1. AH reduced the hematoma volume and percentage edema of the ISH-induced rat brain. 2. AH swollen apoptotic bodies and neurons in the peri-hematoma regions of the ISH-induced rat brain. 3. AH significantly reduced c-Fos, MMP-9 and MMP-12 positive cells in the peri-hematoma regions of the ISH-induced rat brain. 4. AH swollen iNOS expressions in the peri-hematoma regions of the ISH-induced rat brain. Conclusion : These results suggest that AH plays an anti-apoptotic neuroprotective effect through control of ISH, suppression of c-Fos, and down-regulation of MMP-9 and MMP-12 expressions in the brain tissues.

  • Idopathic thrombocytopenic purpura(ITP) is the most common autoimmune hematologic disorder. The use of glucocorticoids and splenectomy have been the mainstays of treatment of ITP Some studies have shown that chinese herbal medicine treatment increase platelet count level of ITP patients. However, there is a lack of research considering oriental herbal medicine with ITP, in korea. A 33-year-old female who had diagnosed ITP on Mar 1999, was treated herbal medicine for decreased platelet count level$(34000/{\mu}l)$ that was identified on regular follow-up. this patient's platelet count level was get to normal$(139000/{\mu}l)$ by BuQiSheXue(補氣攝血) pattern herbal medicine that composed with Radix Astragali(黃?), Herba Agrimoniae(仙鶴草), Rhizoma Atractylodis Macrocephalae(白朮), Radix codonopsis(黨參), etc. I report the case with a review of literature.

  • Objectives : The aim of this study is to examine the effect of external application containing herbal extracts (Betula platyphyllae Cortex, Viticis Fructus, Agrimoniae herba) to patients with atopic dermatitis. Methods : Twenty patients (experiment group) were treated with the external application containing herbal extracts (Betula platyphyllae Cortex, Viticis Fructus, Agrimoniae herba) and other twenty patients (control group) were treated with normal external application that doesn't contain herbal extracts for 2weeks. We observed comparisons between experiment and control group after 1week, 2weeks. Degrees of severity of atopic dermatitis were measured by SCORAD index (Scoring of Atopic Dermatitis Index). Statistical significance was achieved if the probability was less than 5% (p<0.05). Results : 1. After 1week of external application treatment, SCORAD Index in experiment group was significantly decreased comparing with control group, which is a marginally significant result between two groups. But after 2weeks the experiment group showed no statistically significant result. 2. After 1week of external application treatment, Intensity Criteria (Erythema, Edema/papulation, Total) in experiment group was significantly decreased comparing with control group, which is a statistically significant result between two groups. But after 2weeks the experiment group showed no statistically significant result. 3. After 1week and 2weeks of external application treatment, comparison of changes in Subjective Symptoms (Pruritus, Insomnia) indicated that the experiment group showed no statistically significant result. 4. After 1week of external application treatment, Total Quality of life through Skindex-29 in experiment group was significantly decreased comparing with control group, which is a marginally significant result between two groups. But after 2weeks the experiment group showed no statistically significant result. Conclusions : As a result of applying the external application containing herbal extracts to patients with atopic dermatitis and watching the progress, we can speculate that the external application containing herbal extracts has especially short-term therapeutical effects in mitigating the symptoms of Atopic Dermatitis. Thus, it is concluded and considered that the external application containing herbal extracts can be used by atopic patients effectively with almost no side-effect.

  • For the development of antimetastatic agent 41 kinds of crude drugs were used for the evaluation of inhibitory effect of several crude drugs on cell adhesion of pulmonary cancer cells and platelet aggregation. Results were obtained as follows: 1. Water extracts of crude drugs inhibited cell adhesion of A549 to complex extracelluar matrix over 40 % of contol were Houttuyniae Herba, Mylabris, Rhei Radix et Rhizoma, Meliae Cortex, Ferula Resina, Oldenlandiae diffusae Herba at the higher concentration of $10^{-3}g/ml$ while those inhibiting cell adhesion of Bl6-Fo over 40 % of control were $10^{-5}g/ml$ of Houttuyniae Herba, Aurantii Fructus, Lithospermi Radix, Zedoariae Rhizoma. Prunellae Spica, Foeniculi Fructus, Rbei Radix, Scutellariae Radix, Meliae Cortex, Ferula Resina and Oldenlandiae diffusae Herba. 2. MeOH extracts of crude drugs at the concentration of $4{\times}10^{-4}g/ml$ inhibiting cell adhesion of A549 specifically to single extracelluar matrix over 40 % of control were Lithospermi Radix, Agrimoniae Herba, Rhei Radix and Ferula Resina to collagen I, Houttuyniae Herba, Lithospermi Radix, Bupleuri Radix, Salviae miltiorrhizae Radix, Orostachys Herba, Sappan Lignum, Meliae cortex ferula Resina and Coicis Semen to collagen Ⅳ, Mylabris, Agrimoniae Herba to laminin, Houttuyniae Herba and Meliae Cortex to fibronectin. 3. NeOH extracts of crude drugs at the concentration of $4{\times}10^{-4}g/ml$ inhibiting cell adhesion of B16-Fo specifically to single extracelluar matrix over 60 % of control were Lithospermi Radix, Salviae miltiorrhizae Radix, Meliae Cortex and Ferula Resina to collagen I, Lithospermi Radix, Bupleun Radix, Saiviae miltiorrhizae Radix, Ferula Resina and Acanthopanacis Cortex to collagen Ⅳ, Bupleuri Radix, Orostachys Herba to laminin, Houttuyniae Herba to fibronectin. 4. MeOH extracts of crude drugs inhibiting platelet aggregation over 40% of ADP control were at the concentration of $50{\mu}g/m{\ell}$ of Houttuyniae Herba, Angilicae gigantis Radix, Zedoariae Rhizoma. Coicis Semen and $100{\mu}g/m{\ell}$ of Ferula Resina, Orostachys Herba, Salviae miltiorrhizae Radix, Curcumac Radix, Carthami Flos, Lithospermi Radix, Gleditsiae Spina, Sappan Lignum, Acanthopanacis Cortex. These results suggest that several crude drugs including Ferula Resina, Houttuyniae Herba, Lithospermi Radix and Salviae miltiorrhizae Radix chiefly have more possibility to exert antimetastatic activity and require in vivo antimetastatic study.

  • Yersinia enterocolitica, which causes yersiniosis, is a bacterium that produces biofilms effectively. The inhibition of biofilm formation provides a method for preventing infections with Y. enterocolitica. In this study, the inhibitory activity of Y. enterocolitica biofilm formation was investigated in a library of 140 edible plant methanol extracts including forest products. It was identified that the biofilm formation could be inhibited by 12 extracts of plants, Agastachis Herba, Agrimoniae Herba, Diospyros kaki leaves, Elsholtziae Herba, Ginkgonis Semen, Lycopi Herba, Melonis Pedicellus, Menthae Herba, Mori Radicis Cortex, Polygoni Multiflori Radix, Prunellae Spica, and Schizonepetae Spica. After changing the solvent to ethanol and water, the greatest inhibition of biofilm formation was produced by a 50% ethanol extract of Polygoni Multiflori Radix. A method to effectively prevent yersiniosis can be developed using the edible plant extracts identified in this study.

  • Streptococcus mutans causes oral diseases, including tooth decay, by producing a biofilm called plaque. Therefore, inhibition of biofilm formation is essential for maintaining oral health. Plants produce a variety of secondary metabolites, which act as starting sources for the discovery of new bioactive chemicals that inhibit biofilm formation of S. mutans. Previous studies have reported on chemicals with antibiotic activity for the inhibition of biofilm formation by S. mutans. In this study, nine plant extracts from Melonis Pedicellus, Agastachis Herba, Mori Cortex Radicis, Diospyros kaki leaves, Agrimoniae Herba, Polygoni Multiflori Radix, Lycopi Herba, Elsholtziae Herba, and Schizonepetae Spica were screened for the inhibition of biofilm formation from a plant extract library. The water-soluble compounds of the extracts did not affect cell growth but selectively inhibited biofilm formation. These results suggest that the selected plant extracts constitute novel biofilm formation inhibitors, with a novel biological mechanism, for improving oral hygiene.

  • Objectives : The aerial parts of Agrimonia pilosa Ledeb (Agrimoniae Herba; AH) has been traditionally used as a Korean medicine to treatment of abdominal pain, sore throat, headaches, bloody discharge, parasitic infections and eczema. In this study, we investigated the effect of AH ethanol extract on lipopolysaccharide (LPS)-induced inflammation in RAW264.7 macrophage cells.Methods : AH was extracted by 30% ethanol (AH-E). Raw264.7 cells were treated with AH-E extract at different concentrations for 30 min and then stimulated with LPS (1㎍/㎖) or without for indicated times. Cell viability was measured by MTT assay, and nitric oxide (NO) production was measured by Griess assay. The expression of inflammatory mediators, iNOS and COX-2 and inflammatory cytokines, TNF-α, IL-1β, and IL-6 was detected by RT-PCR, and the phosphorylation of ERK1/2, p38 and JNK MAP kinases (MAPKs) was analyzed by Western blot. Also, the expression of NF-κB in nuclear and cytosol was detected by Western blot.Results : AH-E extract significantly decreased LPS-induced NO production in RAW264.7 cells. AH-E extract inhibited the mRNA expression of iNOS, COX-2, TNF-α, IL-1β, and IL-6 in LPS-stimulated cells with a dose-dependent manner. In addition, the phosphorylation of ERK, p38 and JNK MAPKs was also inhibited by AH-E extract. AP-E extract inhibited the nuclear translocation of NF-κB in LPS-stimulated cells.Conclusions : Our results suggest that AH-E extract has an anti-inflammatory activity in macrophages-mediated inflammation.

  • Dermatomyositis is an inflammatory cutaneo-muscular disease of unknown etiology, characterized by symmetrical proximal muscle weakness and typical dermatologic manifestation. Henoch-Schonlein purpura is most common in children. In Korea, dermatomyositis or Henoch-Schonlein purpura associated with herbal medicine has not been reported. The subject patient is a seven year-old girl diagnosed with dermatomyositis in August 1999 and Henoch-Schonlein purpura in January, July 2001. There were symptoms of dermatomyositis such as headache, arthralgia, eruption, itching and abdominal pain. I think the herb-prescription composed or Radix astragali (Huangqi), Herba agrimoniae (Xianhecao), Fructus jujubae (Dazao) had an ameliorating effect on Henoch-Schonlein purpura by decreasing these symptoms.
