Asthma is a chronic inflammatory disease of the lungs, characterized by increased sensitivity to bronchoconstriction associated with infiltration of immune cells and mucus hyper secretion. In South Africa, the indigenous plant Siphonochilus aethiopicus, is used by traditional health practitioners to treat colds and flu, wheezing of the chest, coughs, influenza, sinus problems and mild asthma. In this study we aimed to investigate the potential anti-inflammatory and immune-modulating properties of S. aethiopicus in vitro. The dried and powdered S. aethiopicus plant material was extracted with organic solvents. The dried extracts were screened in vitro in the transcription response, NF-${\kappa}B$ and a cytokine assay. Significant activity was observed for organic extracts of the plant in these assays. This study provides evidence that S. aethiopicus has anti-inflammatory and immune-suppressing properties in vitro. These findings may support anecdotal accounts of its effectiveness against allergic asthma.

Hop cones (Humuli Strobili) are the female inflorescences of hop plants (Humulus lupulus L.) belonging to the family Cannabaceae. They have been used as herbal remedies to treat mood and sleep disturbances, and mainly to add as a bittering ingredient in brewing process. Considerable interests on pharmacological and biological activities of hop cones have been focused on their major constituents, namely, phloroglucinols (humulone, lupulone), terpenes (myrcene, humulene), and prenylated flavonoids (xanthohumol, isoxanthohumol, 6-prenylnaringenin, and 8-prenylnaringenin). The present review describes and discusses biological activity profiles of these major compounds in the hop cones.

The dried Prunus mume, an alkaline food abundant in organic acids (citric acid, malic acid and tartaric acid), has been largely used in both folklore remedies and Chinese herbal medicine for a long time. This study was performed to investigate the antimicrobial activity of the dried Prunus mume. The fractionation of the methanol extracts from Prunus mume was conducted using petroleum ether, chloroform, ethyl acetate and butanol, respectively. The antimicrobial activity of the Prunus mume extracts was then determined against food-borne pathogens using a paper disc method. The ethyl acetate extract showed the strongest antimicrobial activity against the eigth food-born pathogens used in this present study. Diaion HP 20 column chromatography was performed to remove some sugars that might inhibit the antimicrobial activity of Prunus mume. The strongest antimicrobial activity of ethyl acetate fraction of Prunus mume was shown against Staphylococus aureus. The growth inhibition curve was determined using ethyl acetate extracts of Prunus mume against Staphylococus aureus, which showed the growth inhibition up to 72 hours at 1,000 ppm concentration.

Objectives : The purpose of this study was to investigate the interpretation of the Ondam-tang(Ondam-tang, here-in-after referred to as "ODT") prescription in order to obtain the evidence for clinical applications. Methods : We have analyzed the interpretation on the ODT prescription through translations and comparisons based on classic books about the oriental medical prescriptions. Result : 1. ODT was first mentioned in the Jiyangfang(集驗方) which was quoted in the Waitaimiyao (外臺秘要). After that, in book Sanyinjiyibingzhengfanglun(三因極一病證方論), Chen-yan(陳言) completed and recorded in a book organizing prescriptions of ODT now in frequent use. 2. The Banha(半夏) removes the dam(痰-phlegm) and relieves emesis. The Jinpee(陳皮) encourages strengths, and the Bokryoung composes oneself and produces the water. The Licorice(甘草) relieves people's mind, and the Ginger relieves gastrointestinal problems and relieves emesis. Juk-yeo(竹茹) abate of the fever of the Sangcho(上焦). Jisil(枳實) encourages strength, controlling Samcho(三焦) as releasing the congestion of energy. In these ways, numerous symptoms resulted from the imbalances of the Gallbladder(膽) are treated. 3. Meaning of "on(溫-warm)" in ODT regains the original characteristic of the Gallbladder(膽). 4. Treatment mechanism of ODT is 'cooling the Gallbladder(膽)' and 'remedies Samcho(三焦)' and 'eliminates dam(痰)' and 'cure Kiwool(氣鬱-which is kind of depressions) and Saengyen(生涎-which is kind of phlegm)' and 'removes a mismatch between Gallbladder(膽) and Stomache(胃)'. Conclusion : In this study, we have demonstrated various methodologies. This paper will be useful to the future researchers and clinicians to conduct a study on herbal medicines such as the ODT.

A large number of edible seaweeds are consumed by the coastal peoples of Asia. Some of them are used in traditional remedies in many parts of the world. In this study we investigated effects of supplementation with ethyl acetate extracts of the brown alga Eisenia bicyclis (EBE) on rat macrophage to evaluate the possibilities as immune-modulators. Twelve male SD rats were divided into two groups and the treatments were as follows: A, no Eisenia bicyclis extract (EBE) intake and distilled water ; B, oral supplemented with EBE 200 mg/kg. After 5 weeks of supplementation, rats were sacrificed to assess the effect on peritoneal macrophage functions. We showed no increasing effects on tumoricidal activity, phagocytic activity and NO production in macrophages in EBE supplementation group. However, EBE supplementation suppressed NO-iNOS production and p65 translocation into the nucleus in LPS-stimulated macrophages. Overall, these results suggest that the supplementation of EBE might have an anti-inflammatory effects on NO-iNOS production in macrophages throughout the inhibition of NF-${\kappa}B$ activation.

Objectives : In Korea the practice of folk remedies is widely spread. One of the main uses is the utilization of pumpkin in postpartum edema. While this practice is widely propagated no one could exactly define the evidence of its uses. Therefore we aimed to provide literature evidence of correct prescription in postpartum edema. Methods : As the use of pumpkin in postpartum edema is particular to korea, we revised all the medical book published from the 17th century, the time supposed to have been introduced pumpkin in Korean peninsula. We also researched the prescription mainly used in postpartum edema, and the common main herbal component, succium. As pumpkin and succium is homophony to 'Ho bak' in korean it had the possibility of being misinterpreted. Results : On our literature research we found the precautions of pumpkin to provoke gi-stagnatio and dampness obstruction and that it was restricted while the recovery of all kind of diseases as well as in puerperium. The main reason of postpartum edema is caused by blood stasis which when the blood gains its normal circulation, edema is dispersed by itself. For this propose main prescription was Jogyeongsan調經散 type with its main component succium which medical properties are cited in all medical classics consistently. From the literature of "Juchonsinbang" and "Uibanghapbu" we found three different prescriptions, Hobakgo琥珀膏, Hobakgo胡朴膏, and Namgwago南瓜膏 which contents and their medical proposes were equal. Conclusions : By these finding we could refer that the use of pumpkin in postpartum edema was caused by homophonic reasonal misinterpretation of succinum in korean. This research provides the literature evidence to correct pumpkin's misuse and also the necessity of restriction of the use of even most common products for medical proposes and/or at least the importance of being guided by the experts.

Objectives: Oriental pear was used as traditional remedies for respiratory diseases like cough and asthma etc. The purpose of this study was to observe the effects of preventing asthma by the combination of phenolic compound extracted from pear and herbal drugs. Methods: In order to study the effects of preventing asthma by the combination of phenolic compound extracted from pear and herbal drugs(Platycodon grandiflorum, Prunus armeniaca) on allergic asthma, mice were pre-treated by oral administration of the solution before antigen sensitization for 10 days and 20days. And 2 days later, mice were actively sensitized with a subcutaneous injection of ovalbumin and 13 days later, they were provoked with ovalbumin aerosols. The experimental groups were divided 6groups(10d1P, 10d2P, 10d4P, 20d1P, 20d2P and 20d4P) by meditation quantity and period. We measured isometric contractile responses to acetylcholine(ACh) and KCl in the isolated tracheal smooth muscle(TSM), IL-4, eosinophil and lymphocyte in bronchoalveolar lavage fluid(BALF), IgE in serum, WBC, RBC and hemoglobin in blood. Results: Contractile responses of TSM to ACh, the sensitivity of TSM to Ach and the maximal contractile response of TSM to KCl were decreased by direct proportion of meditation quantity. Eosinophil and IL-4 level in BALF were more significantly decreased, and IgE level in serum was more significantly increased in 10d4P and 20d4P group than the control group. Conclusions: Based on the above results, it is assumed that oral administration of the combination of phenolic compound extracted from pear and herbal drugs(Platycodon grandiflorum, Prunus armeniaca) can help the preventing effects of allergic asthma.
