  • Objectives : We aimed to determine therapeutic effects of probiotics-fermented Magnolia denudata(MD) in the allergic rhinitis model mice. Methods : Polyphenol production, DPPH radical scavenging activity and NO inhibition of fermented MD by different bacterial strains were evaluated to select the one that is most suitable for fermentation. Thirty C57BL/6 mice were divided randomly into 5 groups as follows: normal group, ovalbumin(OVA)-treated plus water fed(CON group), OVA-treated plus unfermented MD fed(UMD group), OVA-treated plus fermented autoclaved MD fed(A-FMD group) and OVA-treated plus fermented unautoclaved MD fed(FMD group). After 9 weeks, we observed changes in the blood cell count, OVA-specific IgE level, nasal rubbing, nasal mucosal tissue and body weight. Results : Extract of MD fermented by Bifidobacterium breve(BB) for 48 hours showed the highest anti-oxidant activity and anti-inflammatory activity out of all the other bacterial strains. The number of eosinophil count in A-FMD, FMD group and platelet count in FMD group showed statistically significant decrease(p<0.05). OVA-specific IgE level decreased in all 3 experimental groups, significantly in UMD and A-FMD group. Nasal symptoms were attenuated in all 3 experimental groups, statistically significant in A-FMD and FMD group (p<0.05). Histologically, infiltration of eosinophils into the nasal mucosa decreased in all 3 experimental groups, especially marked decrease in FMD group. Conclusions : According to the above results, it is considered that probiotics-fermented Magnolia denudata has inhibitory effects on the allergic rhinitis animal models.

  • Objectives The purpose of this study is to analyze studies about the effects of topical application of Chinese herbal medicine for allergic rhinitis within randomized controlled trials (RCT). Methods The search database includes KJTK (Korean Traditional Knowledge Portal), OASIS (Oriental Medicine Advanced Searching Integrated system), CNKI (China National Knowledge Infrastructure), PubMed, and EMBASE. We used the following key search terms: "allergic rhinitis", "traditional Chinese medicine", "traditional Korean medicine", "Chinese herbal medicine", "randomized controlled trial", "clinical study", "nasal spray", and "nasal drop" Results Five studies were selected for analysis. Three studies used nasal spray of Chinese herbal medicine and two studies used nasal drops of Chinese herbal medicine for the intervention. Frequently used herbs were Magnoliae Flos (辛夷), Scutellariae Radix (黃芩), Coptidis Rhizoma (黃連), and Astragali Radix (黃芪). For the outcome measures, studies used symptom score, questionnaire of Quality of Life, nasal airway resistance, or laboratory studies. From all 5 studies, it has been shown that topical application of Chinese herbal medicine was effective for improving symptoms of allergic rhinitis. Two out of five studies showed statistical difference between study group and control group. Conclusions This study shows that topical application of Chinese herbal medicine can improve symptoms of allergic rhinitis. Well-designed RCT studies with low risk of bias and studies with outcome measures for assessing the immunomodulatory effects are necessary to confirm these findings.

  • Leukotriene $B_4\;(LTB_4)$ is a pro-inflammatory mediator synthesized in myeloid cells from arachidonic acid. Elevated levels of $LTB_4$ have been found in a number of inflammatory diseases and levels are related to disease activity in some of these. Because $LTB_4$ interacts with cells through specific cell surface receptors, $LTB_4$ receptor blockade is the most specific approach to reduce the pathogenic role of $LTB_4$. In order to find $LTB_4$ receptor antagonist from plants, we screened the $LTB_4$ receptor antagonistic activity of the methanol extract and solvent fractions of herbal drugs. The ability of samples to inhibit specific binding of $[^3H]-LTB_4$ to human peripheral neutrophils was used as assay to evaluate the antagonistic activity of plant materials. Among the tested methanol extracts of herbal drugs, Mori Radicis Cortex, Perillae Semen, Armeniacae Semen and Sophorae subprostratae Radix showed potent inhibitory activity above 70% at the concentration of $100\;{mu}g/ml$. The inhibitory activities of $LTB_4$ binding to human neutrophils were evaluated for several solvent fractions at three different concentrations. Especially, hexane soluble fractions of Anemarrhenae Rhizoma and Embeliae Radix, and ethyl acetate soluble fractions of Aristolochiae Fructus, Magnoliae Cortex and Zingiberis Rhizoma crudus showed moderate activity at $25\;{mu}g/ml$. These fractions were promising candidates for the study of the activity-guided chromatographic purification of active compounds. Silica gel column chromatography of hexane soluble fractions of Anemarrhenae Rhizoma and Embeliae Radix gave very active sub-fractions, AA-4 and ES-4, and their inhibition activities of $LTB_4$ binding to human neutrophil at $30\;{mu}g/ml$ were 78% and 62%, respectively. From these results we could anticipate new $LTB_4$ receptor antagonist from herbal drugs, and the block of $LTB_4$ effects may provide beneficial in neutrophil mediated diseases such as inflammation and bronchial asthma.

  • Objectives: The purpose of this study was to understand the status of reporting and characteristics of adverse drug reactions (ADRs) induced by herbal drugs and to make a suggestion for the domestic pharmacovigilance system on herbal medicine. Methods: We carried out a hospital-based observational study at Dongguk University Ilsan Oriental Hospital from April 2012 to December 2014. We reviewed all the herbal-drug-associated ADRs reports registered to the spontaneous ADR reporting system in electronic medical records of the hospital in the period. Results: We found out 101 reports including 163 herbal-drug-associated ADRs from 97 patients. Females (69.3%) outnumbered males and the most frequent age group was the 50s (44, 27.0%). No serious adverse event was observed. The most commonly reported ADR was gastro-intestinal system disorders (68, 41.5%) followed by skin-related disorders (42, 25.8%). Diarrhea (29, 17.8%) was the most frequently referred clinical manifestation. Most ADRs were induced by internal medicines (160, 98.2%) including manufactured (36, 22.1%) and self-prepared decoction (160, 76.1%). The pairs of Igi-hwan-diarrhea, gamiboa-tang-vomiting, and Magnoliae Flos-gastro-intestinal-system-related ADRs were observed twice each and the others appeared only once. Conclusions: We propose Korean government to take an initiative in national pharmacovigilance system for herbal medicine. To perform the surveillance on herbal drugs, the Association of Korean Medicine (AKOM) should set up a nationwide network by designating centers connecting the Korean medical hospitals, local Korean medicine clinics, and the public health centers. The government and AKOM should also educate and encourage them to understand the pharmacovigilance system and report the ADRs actively.

  • Directional words like 'ascending(升, sheng)', 'descending(降, jiang)', 'floating(浮, fu)', 'sinking(沈, chen) are technical terminologies of Oriental Medicine to express the directions of material medica functioning-at the phase of Qi-superiorly, inferiorly, exteriorly, and interiorly in human body, and are constituting one of the major principles in prescribing medicines. Lacking the objective methodology to measure or, at least determine Qi, However, we can not expect to secure meaningful data to verify those directional terms. This problematic situation caused chaotic discrepancy between theory and practice of Oriental Medicine. Thus, adopting the method of dynamic meditation 'Hanalmomjit' of Lux Vitae meditation society, by which various state of Qi-sensational movements can be expressed, we compared its moves with the directional terms of traditional canons in Oriental Medicine. In this thesis, the experiment of expressing materia medica via 'Hanalmomjit' is resulted out and compared with the terms, confirmed to have a certain meaningfulness. The new method showed these results below: Herba Menthae, described to have the disposition of ascending and floating, showed 60% of ascending movements in 'Hanalmomjit' experiment. Radix Rehmanniae Praeparata, described to have the disposition of descending and sinking, showed 50% of descending movements. Radix Glycyrrhizae, described to have plain disposition, showed 60% of central movements. Rhizoma Atractylodis and Pericarpium Citri Reticulatae, described to have the disposition of ascending and floating, showed also ascending movements. Cortex Magnoliae Officinalis, described to have the disposition of descending and sinking, showed also descending movements. In conclusion, qi-sensational movement of 'Hanalmomjit' for materia medica showed sufficient relations described in classics, proving itself to be useful method for objective demonstration of material medica.

  • Background and Objectives : There are three kinds of formulas for purging the spleen to cure its sthenic syndrome based on the types of preparation formulas : Sabeetang, Sabeehwan, Sabeesan and Sabeeeum. Another formulas called Sahwangtang, Sahwangsan. Sahwangeum is to purge the yellow colour of spleen. There are 8 kinds of Sabeetang, 3 kinds of Sabeehwan, 3 kinds of Sabeesan, 1 kind of Sabeeeum, 4 kinds of Sahwangtang, 7 kinds of Sahwangsan, and 1 kind of Sahwangeum. Combination of herbal medicines, carried out in formulas for purging the spleen, consists of various kinds depending on medical scientists' personal experience in medical treatment without any general principles, which makes it difficult to apply it to clinical use. The objectives of this study lie in theoretical establishment of Sabeetang for curing the sthenic syndrome of spleen through analyzing the component medicines and combination principles of Hyeongok's Sabeetang, and furthermore, maximizing the clinical use of Sabeetang. Methods : This study analyzed the component medicines and combination principles of Hyeongok's Sabeetang based on the theory for properties and tastes of herbal medicines from the ${\ulcorner}$Yellow Emperor's Canon of Internal Medicine${\lrcorner}$ , the theory for principal herbal medicine, assistant herbal medicine, adjuvant herbal medicine, dispatcher herbal medicine, and the five elements doctrine. Hyeongok's Sabeetang is an odd prescription, composed of 7 kinds of ingredients : No.1 Rhizoma Coptidis (2don;7.5g), No.2 Fructus Gardeniae (1don;3.75g), No.3 Ramulus Cinnamomi (1don), No.4 Gypsum Fibrosum (1don), No.5 Fructus Aurantii Immaturus (1don), No.6 Cortex Magnoliae Omcinalis (1don), and No.7 Radix Et Rhizoma Rhei (1don) Results : There are three methods for curing the sthenic syndrome of spleen according to the five elements doctrine : purging the spleen, purging the lung and invigorating the liver. First, if you suffer from the sthenic syndrome of the spleen, you need to purge your spleen. There are two available methods, including taste and property purgation according to the theory for properties and tastes of herbal medicines. They each imply the bitter taste and the cool property purge the spleen. In the case of taste purgation, two herbal medicines with bitter taste. Rhizoma Coptidis and Fructus Gardeniae, are combined into the principal and assistant herbal medicine, respectively. For property purgation, three herbal medicines with the cool property, Gypsum Fibrosum, Fructus Aurantii Immaturus and Radix Et Rhizoma Rhei, are combined into adjuvant herbal medicines. Secondly, if you suffer from the sthenic syndrome of the spleen, you need to purge your lung which is child in the mother-child relationship in inter-promotion among the five elements. There are two methods to purge the lung, including taste and property purgation according to the theory for properties and tastes of herbal medicines. They each mean the pungent taste and the warm property purge the lung. Therefore, it is important to use pungent herbal medicines for taste purgation and warm ones for property purgation. Both pungent and warm herb and property invigoration to invigorate the liver with warm property. Therefore, it is important to use pungent herbal medicines for taste invigoration and warm ones for property invigoration. Both pungent and warm herbal medicines, Ramulus Cinnamomi and Cortex Magnoliae Officinalis, were combined to invigorate the liver and purge the lung. In addition, Gypsum Fibrosum are combined as dispatcher herbal medicine, leading all the herbal medicines composing the formula to the spleen. Conclusions : First, to cure the sthenic syndrome of the spleen, the methods of purging the spleen and the lung, and invigorating the liver should be used according to the five elements doctrine. Secondly, herbal medicines appropriate for those treatment methods should be chosen according to the theory for properties and tastes of herbal medicine and thirdly, the combination of those herbal medicines should be carried out according to the theory for principal herbal medicine, assistant herbal medicine, adjuvant herbal medicine, dispatcher herbal medicine. As a good example, Hyeongok's Sabeetang is combined according to the above theories. In conclusion, this formula was created by applying to the theory for properties and tastes of herbal medicines.

  • Chung-Sang (CS) is an experimental herbal remedy that is formulated to treat respiratory diseases implicated by inflammation. The herbs comprised of CS are frequently prescribed for treating various inflammatory symptoms: Menthae haplocalycis Herba, Magnoliae Flosis, Xanthii Fructus, Herba Asari, and Caryphylli Flos. Here, we prepared the extract of CS with boiling water (wCS) or with 50 % ethanol (eCS) and examined whether the two different extracts of CS exhibit a toxicity to cultured cells and mice. RAW 264.7 cells were treated with wCS or eCS, and the cytotoxicity of these extracts to RAW 264.7 cells was determined by an MTT assay. Although the production of intracellular reactive oxygen species that are detrimental to the cells was not increased by the extracts, the cytotoxicity to the cells was evident from 10 mg/ml of wCS and 100 mg/ml of eCS, suggesting that eCS is less cytotoxic. When mice (n = 10/group) received a single intratracheal wCS or eCS daily for 14 days, wCS yielded 40 % mortality, whereas eCS showed none. Both wCS and eCS did not significantly affect the weight of the body and of vital organs, except the lung. Biochemical analyses of mice blood indicated no damage to liver or kidney. However, unlike eCS, wCS significantly increased the level of IgE in serum. Collectively, our results show that eCS was less toxic than wCS, suggesting that CS prepared with 50 % ethanol is preferential over the conventional way of preparing CS.
