  • Inflammatory bowel disease (IBD), characterized by chronic inflammation of the gut, is caused by several factors. Among these factors, microbial factors are correlated with the gut microbiota, which produces short-chain fatty acids (SCFAs) via anaerobic fermentation. Fermented foods are known to regulate the gut microbiota composition. Ganjang (GJ), a traditional fermented Korean soy sauce consumed worldwide, has been shown to exhibit antioxidant, anticancer, anti-colitis, and antihypertensive activities. However, its effects on the gut microbiota remain unknown. In the present study, we aimed to compare the anti-inflammatory effects of GJ manufactured using different methods and investigate its effect on SCFA production in the gut. To evaluate the anti-inflammatory effects of GJ in the gut, we performed animal experiments using a mouse model of dextran sulfate sodium (DSS)-induced colitis. All GJ samples attenuated DSS-induced colitis symptoms, including reduced colonic length, by suppressing the expression of inflammatory cytokines. In addition, GJ administration modulated SCFA production in the DSS-induced colitis model. Overall, GJ exerted anti-inflammatory effects by reducing DSS-induced symptoms via regulation of inflammation and modulation of SCFA levels in a DSS-induced colitis model. Thus, GJ is a promising fermented food with the potential to prevent IBD.

  • Centella asiatica (Linn.) Urban (Umbelliferae) which is also known as 'pegaga' is highly consumed and eaten raw as 'ulam' in Malaysia. C. asiatica is used in traditional medicines to treat various health conditions such as rheumatism, inflammation, syphilis, skin diseases and diarrhoea. Various reports exhibited that the crude extracts and isolated bioactive compounds of C. asiatica possessed a broad range of pharmacological activities such as anti-oxidant, anti-diabetic, anti-tumor, wound healing, anti-microbial, anti-inflammatory, immunomodulatory, hepatoprotective and memory enhancing properties. The pharmacological validation on anti-microbial and immunomodulatory of C. asiatica is very limited and several existence review papers related for this plant had not been focused for both activities. This review therefore attempts to combine the existing literature to offer immense scope for researchers engaged in validation of the traditional claims and bioactivities of this plant related with anti-microbial and immunomodulatory potential.

  • In this study, we assessed anti-oxidant activity, anti-microbial, inhibition of biofilm formation and inflammatory factors(nitric oxide, interleukin-6, interleukin-8) inhibitory effect of Perillae semen hydrothermal extract(PSW) and three kinds of Perillae semen supercritical fluid extract(PSSs) extracted by controlling temperature with no variation of pressure. Compared with PSW, PSSs had significantly lower minimal inhibitory concentrations(MICs) against Staphylococcus aureus(S. aureus) and the ability of PSSs to inhibit formation of biofilm was also superior. PSSs reduce the production of inflammatory mediator and inflammatory cytokines significantly compared to PSW. We suggest, therefore, Perillae semen supercritical fluid 45℃ extract which showed the best anti-microbial, inhibition of biofilm formation, and inhibition of inflammatory factors production among the supercritical fluid extracts could be used for protecting patients with atopic dermatitis from pruritus and transepidermal water loss as a functional ingredient from nature.

  • Chamomile (Matricaria chamomilla), a member of the Asteraceae family, is a well-known for medicinal plant and can be found in India and Europe. Chamomile is an effective sedative and various medical effects. But, the effects of acne treatment by chamomile were not investigated. Therefore, we assessed the anti-oxidant effects, anti-microbial activity and anti-inflammatory effects by chamomile extracts in HaCaT keratinocyte cells. Anti-oxidant effects of chamomile extracts were investigated by DPPH assay. Also, results of MTT assay was demonstrated that chamomile extracts did not have a cytotoxic effect in HaCaT cells. To assess the antimicrobial activity, we determined formation of inhibition zone of Propionibacterium acnes by extracts from chamomile. Tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) induces production of inflammatory cytokines such as interleukin-$1{\beta}$ (IL-$1{\beta}$), IL-6 and IL-8 and expression of COX-2. Chamomile extracts could inhibit TNF-${\alpha}$-induced mRNA expression levels of IL-$1{\beta}$, IL-6, IL-8 and COX-2 gene. These results demonstrated the possibility of chamomile for prevention and treatment of skin inflammatory diseases such as acne.

  • Objectives: The purpose of this study was to investigate the in vitro anti-inflammatory, anti-pruritic and antimicrobial effects of the three herbal prescription (EST, SCT, WDT), which has been traditionally used for treating leukorrhea induced by various infections in the female genital tract. Methods: In this experiment, the anti-inflammatory effects were evaluated by Nitric oxide (NO), $Interlukine-1{\beta}$ ($IL-1{\beta}$), Interlukine-2 (IL-2), Interlukine-6 (IL-6), Tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$), Prostaglandin $E_2$ ($PGE_2$), Leukotriene $B_4$ ($LTB_4$) production amount and Inducible nitric oxide synthase (iNOS), Nuclear factor kappa B ($NF-{\kappa}B$), Cyclooxygenase-2 (COX-2) gene expression levels in RAW264.7 cells. And the anti-pruritic effects were evaluated by Histamine, Acetylcholine (ACh), Acetylcholinesterase (AChE), Substance P production amount in Mast cell/9 (MC/9) and Pheochromocytoma 12 (PC12) cells. The anti-microbial effect was measured by inhibition zone diameter on Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Candida albicans and Aspergillus niger. Results: As a result of measuring anti-inflammatory efficacy, $IL-1{\beta}$, IL-2, IL-6, $TNF-{\alpha}$, $PGE_2$, and $LTB_4$ production amounts were significantly reduced in the EST, SCT, WDT extraction groups compared with the control group, and significantly decreased the amount of $NF-{\kappa}B$, iNOS, and COX-2 gene expression and the amount of Phospho-Inhibitor kappa B alpha ($p-I{\kappa}B-{\alpha}$)/Inhibitor kappa B alpha ($I{\kappa}B-{\alpha}$) and $NF-{\kappa}B$ p65 protein expression. In addition, As a result of measuring the anti-pruritic effect, the amounts of histamine, ACh and Substance P were significantly decreased, and AChE production was slightly decreased, but it's significance did not appear. Finally the anti-microbial effects of EST, SCT, WDT extraction groups against Pseudomonas aeruginosa, Candida albicans and Aspergillus niger was inhibited, however the growth of Escherichia coli and Staphylococcus aureus was not inhibited. Conclusions: These data suggest that EST, SCT, WDT can be used to treat patients with leukorrhea.

  • Objectives : To investigate the effects of Ohbaesangami (OBSGM) on mucosa and skin diseases, anti-microbial and anti-inflammatory tests were performed using several in vitro test models. Results : In anti-microbial test, OBSGM showed the slight inhibitory effect against Propionibacterium acnes (P. acnes) and Staphylococcus aureus (S. aureus). In anti-oxidant test, OBSGM showed the potent radical scavenging activity. In anti-inflammatory test, OBSGM weakly inhibited the lipopolysaccharide (LPS)-induced nitric oxide(NO) release from the RAW 264.7 macrophage cells. OBSGM also inhibited the LPS-induced $interleukin-1{\beta}(IL-1{\beta})$ and cyclooxygenase-2 (COX-2) expressions. The inhibitory effects of OBSGM on macrophage activation was via the inhibition of $NF-{\kappa}B$, evidenced by transient transfection assay. Furthermore, OBSGM markedly inhibited the activation of Jun-N-terminal kinase (JNK) and p38 MAP kinase in RAW 264.7 cells. In skin wrinkle formation assay, OBSGM strongly inhibited collagnease and elastase, whose activities are tightly related with the wrinkle formation. In addition, OBSGM inhibited the activities of MMP-1, MMP-2 on the mRNA levels in RAW 264.7 cells. However, OBSGM did not show an inhibitory potential on tyrosinase activity and melanin synthesis, indicating that it could not be applicable for skin whitening. Conclusion : These results suggest that the anti-inflammatory effect of OBSGM may be due to its inhibitory potentials on the macrophage activation. And, the anti-wrinkle effects of OBSGM may be due to its inhibitory potential on the collagnease and elastase activities. Therefore, OBSGM could be applicable for the treatment of mucosa and skin diseases.

  • Natural essential oils showed anti-microbial activity on relatively broad spectrum of bacterial and fungal species. These materials had much more intensive anti-microbial activities than synthetic preservatives on C. albicans, A niger, and P. acnes, especially. In the experimental group, anti-microbial activity was order of tea tree oil (from Melaleuca alternifolia) > methylparaben > phytoncide (from Chamaecyparis obtusa). Also, natural essential oils had anti-oxidative and anti-inflammatory effects. These results suggest that natural essential oils can be useful as good cosmetic ingredients such as natural preservatives and anti-oxidants.
