  • Objectives : The aim of this study was to evaluate whether herb mixture extract (HME) would affect allergic contact dermatitis induced by 1-chloro-2,4-dinitro-chlorobenzene (DNCB) in mice. For this, the level of blood IgE was identified. To evaluate anti-inflammatory effect of HME, we tested HMC-1 cells stimulated by PMA+A231867. Methods : In order to evaluate allergic contact dermatitis effects we observed HME on contact-hypersensitive skin of Balb/cmice induced by 0.5% DNCB and measured concentration of IgE in blood of Balb/c mice. In order to evaluate anti-inflammatory effect of cytokine expression we used the method of enzyme-linked immunosorbent assay. Results : We confirmed deep wounds, erosions, progress of keratinization and drop out of dead skin cells from Balb/c mice induced by 0.5% DNCB. We also observed a remarkable decrease in symptoms of atopic dermatitis in the group that received injection of 200mg/kg HME. In addition, in the measurement outcome for IgE concentration in blood, we confirmed that IgE concentration was increased by treatment with DNCB only, while it was markedly decreased by treatment with HME. We confirmed that cytokine expression decreased through enzyme-linked immunosorbent assay and pERK, pJNK, and pp38 also decreased through western blot test Conclusions : According to the above results, HME has some effect on alleviating symptoms of allergic contact dermatitis and has anti-inflammatory effects.

  • Objectives : This experimental study was performed in order to investigate the antibacterial effect of bio-fermented Galla Rhois extract. Methods : The Galla Rhois extract was fermented by Streptococcus thermophilus, Saccharomyces cerevisiae and Lactobacillus delbrueckii, and their products was tested for antibacterial activity against six pathogenic microorganisms namely, Bacillus cereus, Bacillus subtilis, Staphylococcus aureus, Vibrio parahaemolyticus, Escherichia coli and Salmonella typhimurium by paper disc diffusion method. Results : The Galla Rhois fermented extract by Lactobacillus delbrueckii and Saccharomyces cerevisiae showed more effective antibacterial activity than not fermented extract against Bacillus subtilis and Vibrio parahaemolyticus. Antibacterial activity of fermented extract using especially Lactobacillus delbrueckii and Saccharomyces cerevisiae was proved that it was good with even 2 percents concentration. Antibacterial activity of Galla Rhois extract within pH 3 to pH 7 had been safe regardless of pH but low over pH 9. The growth of Bacillus cereus, Staphylococcus aureus, and Vibrio parahaemolyticus had a tendency to decrease depend on the increasing concentration of the extract. EtOEt, EtOAc and n-BuOH fractions of the Galla Rhois extract had a high level of antibacterial activity against Bacillus cereus, Bacillus subtilis, Staphylococcus aureus and Vibrio parahaemolyticus, respectively. Surprisingly, EtOAc fractions of the Galla Rhois extract showed higher antibacterial activity against Vibrio parahaemolyticus alone. And antibacterial activity against six pathogenic microorganisms had a tendency to increase depend on the increasing concentration of the fractions of the Galla Rhois extract. Conclusions : Bio-fermented Galla Rhois extract, efficiently inhibited the growth of Bacillus cereus and Vibrio parahaemolyticus.

  • Red ginseng extract was added to Yanggaeng to determine a practical use for the herb which has medical usage and functionality. We examined the antioxidant activity and quality characteristics of Yanggaeng prepared with different amounts (as ratios of 1%, 2%, 3% to the total materials) of red ginseng extract, as well as those of commercial red ginseng Yanggaeng. The antioxidant activity of the Yanggaengs samples was estimated by the DPPH free radical scavenging activity, $ABTS^{+\cdot}$ scavenging activity, and reducing power. The antioxidant activity of the Yanggaeng increased as a result of the addition of the red ginseng extract. Levels of polyphenol compounds and flavonoids increased according to the extract concentration. The quality characteristics of the red ginseng Yanggaeng were estimated in terms of pH, sugar content, viscosity, color, texture profile analysis, and sensory evaluations. With increasing concentrations of the extract, viscosity and sugar content increased, but pH decreased. In terms of the overall palatability, color, taste, flavor, and hardness, the 3% red ginseng Yanggaeng was determined as the best among the tested samples. Also, the 3% red ginseng Yanggaeng had higher scores than the commercial red ginseng Yanggaeng.

  • Rubia cordifolia Linn, which belongs to the Rubiaceae family, is a well-known herb used in Ayurvedic medicine. In the present study, we investigated the influence of a methanolic extract (RC) on the induction of apoptosis in HEp-2 (human laryngeal carcinoma) cell line, as evidenced by cytotoxicity, morphological changes and modification in the levels of pro-oxidants. Inhibition of cell proliferation and lactate dehydrogenase (LDH) release increased in a time and dose-dependent manner. Further, reduced glutathione (GSH), glutathione transferase (GST) and protein levels decreased and lipid peroxidation increased significantly on RC treatment in a dose dependent manner when compared to controls. Based on the results we determined the optimal dose as 30mg/ ml and the apoptotic effect of RC extract (30 mg/ml) on HEp-2 cells was confirmed by fluorescent microscopy and transmission electron microscopy (TEM) based on morphological and ultrastructural changes. RC extract suppressed the proliferation of HEp-2 oral cancer cells inducing apoptotic cell death in vitro. These results point to potential of RC extract as an agent for the treatment of laryngeal squamous cell carcinoma.

  • Objectives : The effects of aqueous extract of Backhapgogumtanggami-bang (BGTG, a newly devised herb medicine) on the induction of apoptotic cell death were investigated in human lymphoid origin leukemia cell lines, HL-60. Methods : Cells were treated with various concentrations and $400{\;}\mu\textrm{g}/ml$ BGTG for 12 hr. Genomic DNA was isolated and separated on 1.8% agarose gels. Lysates from the cells were used to measure the activity of caspase-2, -3, -8, and -9 protease by using fluorogenic peptide. Cells were preincubated with SB-203580 for 30 min. Nuclear protein from the cells was incubated with oliginucleotide probe of AP-l and NF-kB. Nuclear extracts from the cells were isolated and reacted with antibodies. Results : The viability of HL-60 cells were markedly decreased by BGTG extract in a dose- and time-dependent manner. BGTG extract induced the apoptotic death of HL-60 cells which was characterized by the DNA fragmentation. The activations of Caspase-2, 3, and 9 were induced by BGTG. However, selective inhibition of the p38 mitogen-activated protein kinase pathways by SB-203580 did not affect the extent of BGTG extract-induced cell death. Furthermore, we observed the transient activations of transcriptional factors such as AP-l and NF-kB. Conclusions : These results suggest that BGTG extract induced apoptotic death of HL-60 cells and caspase activations as well as the modulation of transcriptional factors such as AP-1 and NF-kB.

  • Traditionally, Ligustrum lucidum fruits (LL) is one of the well-known oriental herb used in the treatment of skin and lung inflammation. This study investigated anti-inflammatory effects of LL in the pathogenesis of acute pulmonary inflammation in mice. Acute pulmonary inflammation was induced by intratracheal instillation of cigarette smoke condensate (CSC) and lipopolysaccharide (LPS) 5 times within 12 days in mice. LL extract was administered orally at a dose of 50 or 200 mg/kg. Administration of LPS and CSC significantly elevated airway hyperresponsiveness (AHR) to mice, and increased in the levels of inflammatory cells and mediators in mice. However, the LL extract significantly reduced the elevated AHR, and the increase of neutrophils, $CD4^+/CD3^+$ cells and $CD8^+/CD3^+$ cells, along with reducing the expression of TNF-${\alpha}$, IL-6, and MIP-2. Moreover, the LL extract alleviated the infiltration of inflammatory cells in expanded airway walls histologically. These results indicate that the LL extract has an inhibitory effects on acute pulmonary inflammation and AHR in murine model, and plays a crucial role as a immunomodulator which possess anti-inflammatory property.

  • We have previously reported that Acer tegmentosum extract, which is traditionally used in Korea to reduce alcohol-related liver injury, suppresses liver inflammation caused by excessive alcohol consumption and might improve metabolism. The active ingredient, 6-O-galloylsalidroside (GAL), was isolated from A. tegmentosum, and we hypothesized that GAL could provide desirable pharmacological benefits by ameliorating physiological conditions caused by alcohol abuse. Therefore, this study focused on whether GAL could ameliorate alcoholic fat accumulation and repair liver injury in mice. During chronic alcohol consumption plus binge feeding in mice, GAL was administered orally once per day for 11 days. Intrahepatic lipid accumulation was measured in vivo using a noninvasive method, 1H magnetic resonance imaging, and confirmed by staining with hematoxylin and eosin and Oil Red O. The serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were measured using a Konelab system, and the triglyceride content was measured in liver homogenates using an enzymatic peroxide assay. The results suggested that GAL alleviated alcohol-induced steatosis,e as indicated by decreased hepatic and serum triglyceride levels in ethanol-fed mice. GAL treatment also correlated with a decrease in the Cd36 mRNA expression, thus potentially inhibiting the development of alcoholic steatosis via the hepatic de novo lipogenesis pathway. Furthermore, treatment with GAL inhibited the expression of cytochrome P450 2E1 and attenuated hepatocellular damage, as reflected by a reduction in ALT and AST levels. These findings suggest that GAL extracted from A. tegmentosum has the potential to serve as a bioactive agent for the treatment of alcoholic fatty liver and liver damage.
