  • Objectives : This study was designed to examine the effects of Daecheonglyong-tang(DCL) on atopic dermatitis induced by DNCB in mice Methods : The Nc/Nga mice were divided into 5 groups, and four groups excluding the normal group were applied by 2,4-dinitrochlorobenzene(DNCB), to cause AD and were orally administered with distilled water(negative control), dexamethasone(positive control), and DCL 200 or 400mg/kg once a day for 4 weeks respectively. The visual changes on skin, changes in skin tissue thickness and eosinophil infiltration were observed. IgE, Histamine, Cytokines, immune cells and the amount of gene expression of filaggrin, VEGF, $TGF-{\beta}1$, EGF were measured. Results : Dermatitis score showed a gross improvement on all DCL groups, similar to or better than positive control. All DCL groups showed no significant change in the basophils, while neutrophils and eosinophils decreased. In only DCL 400 mg/kg groups, white blood cells and mononuclear cells were decreased and lymphocytes were increased. In particular, neutrophils had similar or better effects than the positive control. In all DCL groups, IgE, Histamine, $IL-1{\beta}$, IL-4, IL-5, IL-6 and $TNF-{\alpha}$ were decreased and IL-2 was increased. In only DCL 400 mg/kg groups, IL-10 decreased and $IFN-{\gamma}$ increased. In particular, $IL-1{\beta}$ and $IFN-{\gamma}$ showed a similar rate of increase and decrease comparing positive control in DCL 400 mg/kg. $TGF-{\beta}$1 was increased in all DCL groups, filaggrin and VEGF were increased in only DCL 400 mg/kg groups. EGF did not make any changes. Epidermis, dermis thickness and eosinophil infiltration were also decreased in all DCL groups. Conclusions : By increasing Th1 cytokine and decreasing Th2 cytokine, DCL extracts appear to be effective in controlling immune response imbalances, anti-inflammatory and skin regeneration and are likely to be available as a treatment for AD.

  • The aim of this study is to evaluate the efficacy of cordyceps militaris extracts for the improvement of cognitive dysfunction in PC12 and BV2 cells. Cordyceps militaris extracts was prepared by extracting with distilled water. Cell viability was assessed by MTT assay using PC12 cells and BV2 cells. Confirmed effects of L-glutamate induced cytotoxicity test, Acetylcoline (ACh) concentration, and Acetylcolinestase (AChE) activity in PC12 cells. Anti-inflammatory activities of cordyceps militaris extracts was measured through changes in the levels of nitric oxide (NO), and prostaglandin E2 ($PGE_2$) on lipopolysaccharide(LPS)-induced BV2 cell. In addition, we measured the expression of $NF-{\kappa}B$, p38, JNK, and caspase-3 in western blot analysis. Cordyceps militaris extracts showed no cytotoxicity at the concentrations of 1, 10, and $100{\mu}g/m{\ell}$ except for the concentration of $200{\mu}g/m{\ell}$. Cordyceps militaris extracts protected the cell and exhibited significant increases in the ACh concentration and a significant decrease in the AChE activity in L-glutamate induced PC12 cells. Moreover, cordyceps militaris extracts inhibited the productions NO, and PGE2 level and the protein expression of $NF-{\kappa}B$, p38, JNK, caspase-3 in LPS-induced BV2 cells. These results indicate that cordyceps militaris extracts possible prevented and improved cognitive dysfuction symptoms. Thus, cordyceps militaris extracts may be a novel natural material option for the improvement of cognitive dysfunction.

  • Periodontal inflammation, a major kind of periodontal diseases, is characterized to bleed, pain, and teeth loss, and it is resulted from oxidative stress. Membrane-free stem cell extract could avoid the immunogencity rejection by removal of cell membrane. In the present study, we investigated the protective effect of membrane-free stem cell extract from oxidative stress-induced periodontal inflammation in human periodontal ligament fibroblasts (HPLF). In the cell viability measurement, membrane-free stem cell extract showed significant increase of cell viability, compared with the $H_2O_2$-treated control group. To further investigation of molecular mechanisms, we measured inflammation and apoptosis related protein expressions. Membrane-free stem cell extract attenuated inflammation-related protein expressions such as nuclear factor kappa light chain enhancer of activated B cells, inducible nitric oxide synthase, and interleukin-6. In addition, the treatment of membrane-free stem cell extract decreased apoptotic protein expressions such as cleaved caspase-9, -3, poly (ADP-ribose) polymerase, and B-cell lymphoma 2 (Bcl-2)-associated X protein/Bcl-2 ratio in the $H_2O_2$-treated HPLF cells. In conclusion, membrane-free stem cell extract exhibited anti-oxidative stress effects by regulation of inflammation and apoptosis in HPLF, suggesting that it could be used as the treatment agents for periodontal inflammatory disease.

  • Phthalate is a chemical endocrine disrupter and interfere with the action of hormones, estrogens, androgens and thyroid hormones. It also affect cardiovascular, metabolic, immune and reproductive system in the human and animals. Curcumin is antioxidant, anti-inflammatory activity and -cancer properties in the human. We studied whether phthalates damage viability, mitochondrial activity and membrane integrity of sperm in boar semen. We also treated curcumin with/without phthalates in the boar semen. Fresh boar semen was treated with phthalates and/or curcumin for examining sperm characteristics. Sperm characteristics, sperm motility, viability, mitochondrial activity, and membrane integrity were determined during storage of boar semen. Sperm motility and viability in dose-dependent manner decreased by di-n-butyl phthalate (DBP), mono-n-butyl phthalate (MBP) and di-2-ethylhexyl phthalate (DEHP, p<0.05). Phthalates also decreased mitochondrial activity and membrane integrity of sperm (p<0.05). However, sperm motility and viability were higher than untreated-curcumin when DBP, MBP and DEHP treated with a curcumin in boar semen (p<0.05). Mitochondrial activity and membrane integrity of sperm were higher in DBP- and MBP-treated semen with curcumin (p<0.05). In conclusion, phthalates can damage sperm viability and quality during the boar semen storage, and curcumin may protect the boar sperms from phthalates during storage term.

  • Wound care is a health industry concern affecting millions worldwide. Recent increase in metabolic disorders such as diabetes comes with elevated risk of wound-based complications. Treatment and management of wounds are difficult practices due to complexity of the wound healing process. Conventional wound dressings and treatment applications only provide limited benefits which are mainly aimed to keep wound protected from external factors. To improve wound care, recent developments make biopolymers to be of high interest and importance to researchers and medical practitioners. Biopolymers are polymers or natural origin produced by living organisms. They are credited to be highly biocompatible and biodegradable. Currently, studies reported biopolymers to exhibit various health beneficial properties such as antimicrobial, anti-inflammatory, hemostatic, cell proliferative and angiogenic activities which are crucial for effective wound management. Several biopolymers, namely chitosan, cellulose, collagen, hyaluronic acid and alginic acid have been already investigated and applied as wound dressing agents. Different derivatives of biopolymers have also been developed by cross-linking with other molecules, grafting with other polymers, and loading with bioactive agents or drugs which showed promising results towards wound healing without any undesired outcome such as scarring and physiological abnormalities. In this review, current applications of common biopolymers in wound treatment industry are highlighted to be a guide for further applications and studies.

  • Alismatis rhizoma (AR), the dried rhizome of Alisma orientale (Sam.) Juzep, is a well-known, traditional medicine that is used for the various biological activities including as a diuretic, to lower cholesterol and as an anti-inflammatory agent. The present study was carried out to investigate the potential toxicity of the Alismatis rhizoma aqueous extract (ARAE) following 90-day repeated oral administration to Sprague-Dawley rats. ARAE was administered orally to male and female rats for 90 days at 0 (control), 500, 1,000 and 2,000 mg/kg/day (n = 10 for male and female rats for each dose). Additional recovery groups from the control group and high dose group were observed for a 28-day recovery period. Chromatograms of ARAE detected main compounds with four peaks. Treatment-related effects including an increase in the red blood cells, hemoglobin, hematocrit, albumin, total protein, and urine volume were observed in males of the 2,000 mg/kg/day group (p < 0.05). However, the diuretic effect of ARAE was considered, a major cause of hematological and serum biochemical changes. The oral no-observed-adverse-effect level (NOAEL) of the ARAE was > 2,000 mg/kg/day in both genders, and no target organs were identified.

  • Background: Astragali radix (A) and Lithospermi radix (L) have long been used as traditional medicines due to their known anti-inflammatory effects. This study aimed at evaluating, their optimal mixing ratio and their functional compounds by investigating the inhibitory effects of mixed extracts of A and L and their active compounds on matrix metalloproteinases (MMPs). Methods and Results: A and L extracts were obtained by extraction at $80^{\circ}C$ using 50% and 70% fermented alcohol, respectively, and then mixed at a ratio of 5 : 5, 6 : 4, 7 : 3 and 8 : 2 (w/w). The activities of MMP-1, MMP-3, and MMP-13 were evaluated in interleukin-1beta ($IL-1{\beta}$)-induced SW1353 cells. The extract mixtures showed synergistic inhibitory effects on MMP-3 and MMP-13, higher than the effects of the individual A and L extracts. The 7 : 3 mixture (ALM16) showed the most effective MMPs inhibitory activity, while among the active ingredients, calycosin-7-O-${\beta}$-D-glucoside and lithospermic acid exhibited excellent MMPs inhibitory activity. Additionally, an HPLC method was established for simultaneous quantification of the effective components of the extract mixtures, and validated by measuring the linearity, precision and accuracy of the limit of detection (LOD) and limit of quantification (LOQ). Conclusions: ALM16 showed the most effective MMPs inhibitory activity. Calycosin-O-${\beta}$-D-glucoside, calycosin and lithospermic acid were identified as useful candidates, as they were the major functional compounds in the MMP inhibitory activity. Summarily, ALM16 might be a highly effective in osteoarthritis management, owing to its because it exhibits a protective effect on cartilage via excellent inhibition of MMPs.

  • The purpose of this study was to investigate the biological activities of an aqueous extract of Angelica gigas (Ag) fermented by Saccharomyces cerevisiae (Sc). First, the soluble solids of the F/3 group, in which the Ag was fermented by Sc for 3 days, decreased from $1^{\circ}Bx$ to $0.9^{\circ}Bx$. On the other hand, the pH increased with the number of days of fermentation. The result of a TLC experiment confirmed that it gradually decomposed into a low-molecular weight sugar form upon fermentation. The total phenolic compounds and flavonoid contents were higher in the fermented group than in the non-fermented group. K and Ca contents were increased by fermentation in the following order: F/3, NF, and F/0 groups. Decursin and decursinol angelate contents were highest in the F/3 group. The DPPH (${\alpha}$, ${\alpha}{\prime}$-diphenyl-${\beta}$-picrylhydrazyl) radical scavenging activity of the NF, F/0, and F/3 groups were 41.89%, 39.51%, and 60.26%, respectively. The inhibition activities of tyrosinase and lipoxygenase were stronger in the F/3 group than in the NF group. This experiment showed that the fermentation of Ag Nakai can lead to an increase in its antioxidant ability, physiological activity, whitening and anti-inflammatory effects. Thus, this oriental herbal medicine can be developed into a functional material that can be utilized in the development of cosmetic products in future.
