Ssanghwa-tang is a medicinal formula that is widely prescribed in Korea to decrease fatigue after an illness. Fermented herbal medicines might be made more efficacious than conventional herbal medicines by increasing the absorption and bioavailability of the active compounds. In this study, Ssanghwa-tang was fermented to produce bioconversion compositions using Lactobacillus fermentum, and six peaks were decreased, four peaks were increased and one peak newly appeared in the HPLC-DAD chromatogram. The structures of the newly-appearing compound (1) and increased (2–5) compounds were identified as follows using NMR and MS: liquiritigenin (1), nodakenetin (2), cinnamyl alcohol (3), decursinol (4), and benzoic acid (5). The decreased compounds were identified to be paeoniflorin (6), liquiritin (7), nodakenin (8), cinnamaldehyde (9), decursin (10), and decursinol angelate (11) using HPLC-DAD analysis with authentic compounds. The high performance liquid chromatography method was used to quantify the eleven constituents in Ssanghwa-tang and fermented Ssanghwa-tang. All calibration curves of the standard compounds exhibited excellent linearity with a R2 > 0.9940.

This study was conducted to determine if oral administration of the novel herbal medicine, KIOM-MA, and itsLactobacillus acidophilus-fermented product, KIOM-MA128, has therapeutic properties for the treatment of atopic dermatitis (AD). Using AD-induced BALB/c mice by Ovalbumin and aluminum hydroxide, the effectiveness of KIOM-MA and KIOM-MA128 on AD was evaluated. Oral administration of KIOM-MA and KIOM-MA128 reduced major clinical signs of AD including erythema/darkening, edema/papulation, excoriations, lichenification/prurigo, and dryness. Interestingly, KIOM-MA128 more significantly improved AD-related symptoms including decrease of IgE level in the plasma as well as reduction of scratching behavior, skin severity in the AD BALB/c model. HPLC analysis showed the significant changes in the constituent patterns between KIOM-MA and KIOM-MA128. Our results suggest that both KIOM-MA and KIOM-MA128 have potential for therapeutic reagent for the treatment of AD, and further, the efficacy is significantly enhanced byL. acidophilusfermentation via increases in its indicator molecule.

Sipjeondaebotang (SJ) has been used as a traditional drug in east-Asian countries. In this study, to provide insight into the biological effects of SJ and SJ fermented by Lactobacillus, we investigated their effects on lipopolysaccharide (LPS)-mediated inflammation in macrophages. The investigation was focused on whether SJ and fermented SJ could inhibit the production of pro-inflammatory mediators such as prostaglandin (PG) E2and nitric oxide (NO) as well as the expressions of cyclooxygenase (COX)-2, inducible nitric oxide synthase (iNOS), tumor necrosis factor (TNF)-α, mitogen-activated protein kinases (MAPKs) and nuclear factor (NF)-κB in LPS-stimulated RAW 264.7 cells. We found that SJ modestly inhibited LPS-induced PGE2, NO and TNF-α production as well as the expressions of COX-2 and iNOS. Interestingly, fermentation significantly increased its inhibitory effect on the expression of all pro-inflammatory mediators. Furthermore, fermented SJ exhibited increased inhibition of p38 MAPK and c-Jun NH2-terminal kinase (JNK) MAPK phosphorylation as well as NF-κB p65 translocation by reduced IκBα degradation compared with either untreated controls or unfermented SJ. High performance liquid chromatography (HPLC) analysis showed fermentation by Lactobacillus increases liquiritigenin and cinnamyl alcohol contained in SJ, which are known for their anti-inflammatory activities. Finally, SJ fermented by Lactobacillus exerted potent anti-inflammatory activity by inhibiting MAPK and NF-κB signaling in RAW 264.7 cells.

This study was conducted to determine if oral administration of the novel herbal medicine, MA, and itsLactobacillus acidophilusfermented product, MA128, have therapeutic properties for the treatment of asthma. Asthma was induced in BALB/c mice by systemic sensitization to ovalbumin (OVA) followed by intratracheal, intraperitoneal, and aerosol allergen challenges. MA and MA128 were orally administered 6 times a week for 4 weeks. At 1 day after the last ovalbumin exposure, airway hyperresponsiveness was assessed and samples of bronchoalveolar lavage fluid, lung cells, and serum were collected for further analysis. We investigated the effect of MA and MA128 on airway hyperresponsiveness, pulmonary eosinophilic infiltration, various immune cell phenotypes, Th2 cytokine production, OVA-specific IgE production, and Th1/Th2 cytokine production in this mouse model of asthma. In BALB/c mice, we found that MA and MA128 treatment suppressed eosinophil infiltration into airways and blood, allergic airway inflammation and AHR by suppressing the production of IL-5, IL-13, IL-17, Eotaxin, and OVA-specific IgE, by upregulating the production of OVA-specific Th1 cytokine (IFN-γ), and by downregulating OVA-specific Th2 cytokine (IL-4) in the culture supernatant of spleen cells. The effectiveness of MA was increased by fermentation withLactobacillus acidophilus.

Herbal Medicine Improvement Research Center, Korea Institute of Oriental Medicine, Daejeon 305-811, Korea.ABSTRACT : Galgeun-tang (GGT) is a traditional medicinal formula that is widely prescribed to treat cold, asthma, andhives in Korea. Fermented herbal medicines can be made more effective than normal herbal medicines by increasing theabsorption and bioavailability of the active compounds. In this study, we fermented Galgeun-tang to produce bioconversionconstituents using Lactobacillus plantarum (GGT144), and found that four peaks were decreased, three peaks wereincreased and two new peaks appeared in the HPLC-DAD chromatogram. After HPLC-DAD-guided fractionation of thenewly-appearing compounds (1 and 5) and the increased (6, 7, and 9) compounds, the structure of the compounds was deter-mined using NMR and MS. Using this approach the compounds were identified to be pyrogallol (1), daidzein (5), liquiritige-nin (6), cinnamyl alcohol (7), and formononetin (9), respectively. In addition, the decreased compounds were identified to bedaidzin (2), liquiritin (3), ononin (4), and cinnam aldehyde (8) using HPLC-DAD analysis with standard compounds. Thehigh performance liquid chromatography method was used to quantify the nine constituents in GGT and GGT144. All cali-bration curves of the standard compounds displayed excellent linearity with a R

Two new polyacetylenes, oploxynes A (1) and B (2), and the known oplopandiol (3) and falcarindiol (4) were isolated from the stem of Oplopanax elatus.

Citrus Unshiu peel (CUP) has been traditionally used in East Asia as a drug for the treatment of vomiting and dyspepsia. However, its effects on inflammation remain unknown. In this study, we investigated the effects of CUP on the production of pro-inflammatory mediators in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. The research focused on determining whether CUP could inhibit the expression of inducible nitric oxide synthase (iNOS), cyclooxygenase (COX)-2 and the activation of nuclear factor (NF)-κB, mitogen-activated protein kinases (MAPKs), as well as the secretion of nitric oxide (NO), prostaglandin (PG) E2, tumor necrosis factor-α (TNF-α) and interleukin (IL)-6 in LPS-stimulated RAW 264.7 cells. We found that CUP represses LPS-induced iNOS and COX-2 gene expression as well as NO , PGE2, TNF-α and IL-6 production. Additionally, CUP inhibited the LPS-induced phosphorylation of extracellular signal-regulated kinase (ERK), p38, and c-Jun NH2-terminal kinase (JNK) MAPK, and suppressed IκBα degradation and nuclear translocation of NF-κB. Collectively, our results indicate that CUP inhibits the production of various inflammatory mediators via blockade of MAPK phosphorylation pursuant to the inhibition of IκBα degradation and the nuclear translocation of NF-κB. These findings are the first to clarify the mechanism underlying the anti-inflammatory effect exerted by CUP in RAW 264.7 macrophage cells stimulated by inflammatory agents.

Ssanghwa-tang (SHT) is a traditional herbal medicine formula that has been used for the development of physical strength, relief of pain, and the reduction of fatigue. In this study, we fermented SHT with Lactobacillus fermentum (L. fermentum), Lactobacillus gasseri (L.gasseri), or Lactobacillus casei (L.casei) to investigate the hepatoprotective effects of SHT and fermented SHT with Lactobacillus on carbon tetrachloride (CCl(4))-induced liver injury in rats. Rats were given CCl(4) (1 ml/kg, 50% CCl(4) in olive oil) intraperitoneally and either SHT or fermented SHTs (15 ml/kg) was administered 30 min before CCl(4). At 24 hr after CCl(4) injection, the levels of transaminases in the serum were markedly increased. These increases were significantly attenuated by either SHT + L. fermentum or SHT+ L.gasseri. However, SHT and SHT + L.casei showed slight suppression of the increase of transaminases. The liver histological changes were diminished by treatment with SHT + L. fermentum. Additionally, the potential hepatoprotective effect of fermented-SHTs correlated with the amount of unknown metabolite which is produced during fermentation process with L. fermentum, L.gasseri, or L.casei. Therefore, these results suggest that the hepatoprotective effect of SHT may be improved by fermentation with L. fermentum and the intestinal bacterial enzyme activities may likely play an important role in the pharmacological action of herbal medicines.

Background Oyaksungisan (OY) has been used as a traditional drug in east-Asian countries. However, its effect on inflammation still remains unknown. In this study, to provide insight into the biological effects of OY and OY fermented by Lactobacillus, we investigated their effects on lipopolysaccharide (LPS)-mediated inflammation in the RAW 264.7 murine macrophage cells. Methods The investigation was focused on whether OY and fermented OYs could inhibit the production of pro-inflammatory mediators such as nitric oxide (NO) and prostaglandin (PG) E2 as well as the expression of inducible nitric oxide synthase (iNOS), cyclooxygenase (COX)-2, tumor necrosis factor (TNF)-α, interleukin (IL)-6, nuclear factor (NF)-κB and mitogen-activated protein kinases (MAPKs) in LPS-stimulated RAW 264.7 cells. Results We found that OY inhibits a little LPS-induced NO, PGE2, TNF-α and IL-6 productions as well as the expressions of iNOS and COX-2. Interestingly, the fermentation significantly increased its inhibitory effect on the expression of all pro-inflammatory mediators. Furthermore, the fermented OYs exhibited elevated inhibition on the translocation of NF-κB p65 through reduced IκBα degradation as well as the phosphorylations of extracellular signal-regulated kinase (ERK), p38 and c-Jun NH2-terminal kinase (JNK) MAPKs than untreated control or original OY. Conclusions Finally, the fermentation by Lactobacillus potentiates the anti-inflammatory effect of OY by inhibiting NF-κB and MAPK activity in the macrophage cells.

Three phospholipids (4-6) and three aromatic amines (1-3) were obtained from the methanol extract of Bombycis corpus. Based on spectral data, their structures have been elucidated as nicotiamide (1), cytidine (2), adenine (3), 1-O-(9Z-octadecenoyl)-2-O-(8Z,11Z-octadecadienoyl) sn-glycero-3-phosphorylcholine (4), 1,2-di-O-hexadecanoyl-sn-glycero-3-phosphorylcholine (5) and 1,2-di-O-9Z-octadecenoyl-sn-glycero-3-phosphorylcholine (6). We examined the effects of compounds on synthesis of NGF in cultured astrocytes. By RT-PCR analysis, expresison of NGF mRNA in astrocytes cultured in serum-starvation increased after the addition of phospholipid (10 microM). The NGF content in the culture medium was significantly increased by compound 5, compared with the control value. These results suggest that three phospholipid compounds isolated from the methanol extract of Bombycis corpus may exert neurotrophic effects by stimulation of NGF synthesis in astrocytes.
