Objectives : The current study is to evaluate the hepatoprotective effect of youngyanggak-san (YGS) on thioacetamide (TAA)-induced acute liver injury in rats. Methods : YGS is composed of Glycyrrhizae Radix, Asiasari Radix, Cimicifugae Rhizoma, Saigae Tataricae Cornu. While N-YGS (non-youngyanggak-san) doesn't include Saigae Tataricae Cornu. Two samples were administrated TAA together for 3 days. Thirty-six rats were divided into four groups. Rats except for the normal group were received TAA (200 mg/kg of body weight, I.P) were divided into three groups (n=9/group) : Group 1 (TAA only), Group 2 (TAA + 200 mg/kg YGS) and Group 3 (TAA + 200 mg/kg N-YGS). Acute liver damage confirmed using histological examination, The factors associated with oxidative stress and liver function activity measured in serum. Also, expressions of inflammation related proteins were investigated by western blot analysis. Results : Oxidative stress factors such as ROS and $ONOO^-$ in the Group 2 was manifested by a significant rise compared with Group 1. YGS markedly decreased the elevated ROS and $ONOO^-$. Furthermore, YGS significantly reduced the levels of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) The nuclear $factor-{\kappa}B$ ($NF-{\kappa}B$) activation induced by TAA led to increase both inflammatory mediators and cytokines. While YGS administration remarkably suppressed such the overexpression. In addition, the histopathological analysis showed that the liver tissue lesions were improved obviously in YGS treatment. Conclusion : YGS provided a hepatoprotective effect on acute liver damage through the suppression of oxidative stress. Especially, this effect enhanced markedly when Saigae Tataricae Cornu is included.

Objective : Reflux esophagitis (RE) is a disease that caused gastric acid reflux and inflammation due to unstable gastroesophageal sphincter, as increasing worldwide respectively. This study was conducted to evaluate the effect of Evodiae Fructus (EF) extract on chronic reflux esophagitis in rats. Methods : The EF was measured antioxidant activity, such as total polyphenol and total flavonoid contents, 1, 1-diphenyl-2-picrylhydrazyl (DPPH) and 2, 2'-azinobis-3-ethyl-enzothiazoline-6-sulfonic acid (ABTS) radical scavenging activity. Rats were divided into 3 groups; Nor (normal group), Con (chronic acid reflux esophagitis rats treatment with water), EF (chronic acid reflux esophagitis rat treatment with EF 200 mg/kg body weight group). A surgically-induced chronic acid reflux esophagitis (CARE) model was established in SD rats, and treated with water or EF 200 mg/kg body weight for 14 consecutive days. Results : Administration of EF to rats of induction of chronic acid reflux esophagitis was found to reduce esophagus tissues injury. Reactive oxygen species (ROS) and produces peroxynitrite ($ONOO^-$) levels of esophagus tissues were significantly decreased in EF compared to Con group. As results of esophagus protein analyses, EF effectively reduce inflammatory-related factors ($NF-{\kappa}Bp65$, $p-I{\kappa}B{\alpha}$, iNOS, $TNF-{\alpha}$, IL-6), and increase anti-oxidant enzyme (Nrf2, HO-1, SOD, catalase, GPx-1/2). Conclusions : These results suggest that EF administration comfirmed that decreased esophagus tissues injury, oxidantive stress, anti-inflammation effect, and increased anti-oxidant effect. Therefore, EF was the potential to be used as a natural therapeutic drug.
Objectives : Tribulus terrestris $Linn{\acute{e}}$ (Tribuli Fructus; TF) has been used to treat hypochondrium, agalactia, nebula, itching and vitiligo in traditional Korean medicine. In this study, we investigated the effects of TF 30% ethanol extract on inflammatory responses in IgE-stimulated RBL-2H3 mast cells. Methods : TF extract was prepared by 30% ethanol. RBL-2H3 cells, a rat mast cell line, were treated with TF extract at different concentrations for 1 hr and then stimulated with DNP-IgE/HSA for indicated times. Cell viability was measured by WST-1 assay. The expression of inflammatory cytokines (IL-4, IL-13 and $IFN-{\gamma}$) mRNA was determined by reverse transcriptase-PCR, and the phosphorylation of ERK1/2, p38 and JNK MAP kinases (MAPKs) was determined by Western blot. The nuclear expression of $NF-{\kappa}B$ p65 in the cells was detected by Western blot and immunocytochemistry, respectively. Results : The treatment of TF extract at 0.1 and $0.2mg/m{\ell}$ significantly decreased the expression of IL-4 and IL-13 mRNA in IgE-stimulated RBL-2H3 mast cells, while significantly increased the expression of $IFN-{\gamma}$ mRNA. TF extract treatment was also inhibited the phosphorylation of ERK1/2, p38 and JNK MAPKs in IgE-stimulated RBL-2H3 mast cells in a dose-dependent manner. In addition, TF extract significantly blocked the translocation of $NF-{\kappa}B$ p65 into the nuclear of cells after IgE stimulation. Conclusions : These results indicate that TF extract inhibits inflammatory response in IgE-stimulated mast cells through blocking MAPKs/$NF-{\kappa}B$ pathway. This suggests that TF extract has an anti-inflammatory activity in mast cell activation.

Objectives : Collagen decrease of Skin appears through various path ways. One of causes may be the Advanced glycation endproducts (AGEs) that combine formation of glucose and protein. The aim of this study was to explore the prevent wrinkle formation of Paeoniae radix (PR) and heated Paeoniae radix (HPR) via AGEs path way. Methods : AGEs formation inhibitory activities of PR and HPR measured using bovine serum albumin, glucose, and fructose. To evaluate the protective effects of PR and HPR in diabetic rats induced with streptozotocin (STZ) and methyl glyoxal (MGO), SD rat were distributed into four groups. Normal rats (Nor), AGEs-induced rats (Con), AGEs-induced rats treated with 100 mg/kg PR(PR), AGEs-induced rats treated with 100 mg/kg HPR (HPR). To induce AGEs, streptozotocin (50 mg/kg) was administered intraperitoneally and after 3 days administrated 100mM methyl glyoxal for 3 weeks. Results : The oral administration of HPR inhibited AGEs in skin tissues compared with PR. The increased reactive oxygen species (ROS) levels in the serum were diminished by HPR treatment. The analyses of kidney and skin tissues proteins indicated that HPR treatment effectively reduced AGEs related protein levels as compared to that by PR treatment. Also, HPR decreased anti-oxidant related protein levels in skin tissues such as catalase, glutathione peroxidase. Moreover, it inhibited the reduction of COL1A2 by decreasing MMP-1. Conclusion : Based on these results, it was suggested that PR and HPR could have Improving effects on wrinkle formation. These evidences provide useful information for the development wrinkle formation treated agent.

Fine dust enters the lungs or blood vessels through the respiratory tract through the air. Recently, due to the fine dust problem, the demand for air purifiers in Korea is also increasing rapidly. Moss is the oldest terrestrial plant, and it is known that it has the property of adsorbing and decomposing heavy metals and fine dust. To compare the effect of reducing fine dust between moss and the existing chemical filter (Hepa), a cube of 1 m3 was manufactured and the amount of fine dust reduction under a controlled environment was compared. Under the fine dust conditions, an umbrella moss filter, rat tail moss filter, feather moss filter, and silk moss filter were inserted for a total of 40 experiments, 10 times each in 4 different situations. The difference between the amount after 30 minutes was statistically significant for all filters. However, as a result of the test, it was confirmed that there was no statistically significant difference between filters for fine dust, mixed gas, CO2, and O2. In particular, it was confirmed that the previously claimed effect of oxygen generation was almost nonexistent. Through this result, it was confirmed that the reduction of fine dust is effective regardless of the species view of moss, and it is expected to replace or supplement the chemical filter of the existing air purifier through future improvement.
BACKGROUND/OBJECTIVES: Previous studies have reported that protein supplementation contributes to the attenuation of inflammation. Serious trauma such as burn injury usually results in the excessive release of inflammatory factors and organs dysfunction. However, a few reports continued to focus on the function of protein ingestion in regulating burn-induced inflammation and organ dysfunction. MATERIALS/METHODS: This study established the rat model of 30% total body surface area burn injury, and evaluated the function of blended protein (mixture of whey and soybean proteins). Blood routine examination, inflammatory factors, blood biochemistry, and immunohistochemical assays were employed to analyze the samples from different treatment groups. RESULTS: Our results indicated a decrease in the numbers of white blood cells, monocytes, and neutrophils in the burn injury group administered with the blended protein nutritional support (Burn+BP), as compared to the burn injury group administered normal saline supplementation (Burn+S). Expressions of the pro-inflammatory factors (tumor necrosis factor-α and interleukin-6 [IL-6]) and chemokines (macrophage chemoattractant protein-1, regulated upon activation normal T cell expressed and secreted factor, and C-C motif chemokine 11) were dramatically decreased, whereas anti-inflammatory factors (IL-4, IL-10, and IL-13) were significantly increased in the Burn+BP group. Kidney function related markers blood urea nitrogen and serum creatinine, and the liver function related markers alanine transaminase, aspartate aminotransferase, alkaline phosphatase, and lactate dehydrogenase were remarkably reduced, whereas albumin levels were elevated in the Burn+BP group as compared to levels obtained in the Burn+S group. Furthermore, inflammatory cells infiltration of the kidney and liver was also attenuated after burn injury administered with blended protein supplementation. CONCLUSIONS: In summary, nutritional support with blended proteins dramatically attenuates the burn-induced inflammatory reaction and protects organ functions. We believe this is a new insight into a potential therapeutic strategy for nutritional support of burn patients.

Cocaine and amphetamine-regulated transcript (CART) is a satiety factor that is regulated by leptin. It was reported that the mice intracerebroventricularly injected with CART showed behavioral changes resembled with the typical behavioral alterations found in the mice carrying disorders in the brain serotonergic (5-HT) system. Hence, this study was conducted to find out the relationships between CART and 5-HT. We first examined the mRNA levels of CART after the injections of para-chlorophenylalanine (pCPA, 300 mg/kg i.p., single injection or daily for three consecutive days) in the rat brains by in situ hybridization using the mouse CART cDNA probe cloned in our laboratory. Systemic administrations of pCPA, a potent inhibitor of tryptophan hydroxylase, the rate limiting enzyme of 5-HT biosynthesis, acutely depletes the brain 5-HT transporter (5-HTT) in the dorsal raphe nucleus (DRN), which reuptakes terminal 5-HT. Results indicated that the mRNA level of CART significantly decreased in the arcuate nucleus, paraventricular nucleus, and lateral hypothalamic nucleus by three days of daily injection with pCPA with no noticeable change detected 24 hrs after the single injection. The message levels of 5-HTT in DRN decreased in both single and three days of injections. Secondly, to investigate whether CART affect to 5-HT, mouse genomic CART gene, which is consist of 3 exons and 2 introns and mouse neurofilament light (NF-L) chain promoter were cloned. Then, we constructed neuron specific expression vector, which was transfected into HeLa cell using lipid-mediated transfection system. Expression of GFP and CART linked to NF-L-chain promoter in the transfected HeLa cell were detected by using fluorescent microscope and RT-PCR. These results confirmed normal expression of DNA constructs in vitro. Then, to increase brain specific expression of CART in vivo transgenic mice carrying CART gene controlled the deleted NF-L-chain promoter were generated by the DNA microinjection into pronuclei of fertilized embryos. Transgenic mice were detected by Southern blot. Further study is necessary to examine CART expression and 5-HTT in these transgenic mice. Therefore, these results suggest that there maybe a positive molecular correlation between CART and 5-HT in responding to the stimuli.

Objectives : This study was designed to investigate the effects of Sunbanghwalmyung-eum gamibang on Monosodium iodoacetate-induced osteoarthritis rats. Methods : Forty Sprague-Dawley (SD) rats were divided into 5 groups of 8 rats each. Osteoarthritis (OA) was induced by injecting MIA (2 mg/50 µl) into the joint cavity of the left knee of SD rats belonging to the experimental group, and normal saline was injected into the joint cavity of the left knee instead of MIA in the normal group. To the normal group and the controlled group (OA group), 2 ml of distilled water was orally administered. To the positive control group (Indomethacin group), indomethacin 2 ml at a concentration of 2 mg/kg, to the low concentration group of SHG (Low group), 2 ml of SHG at a concentration of 2 mg/kg, and to the high concentration group of SHG (High group), 2 ml of SHG at a concentration of 4 mg/kg ml was orally administered. The drug was administered for a total of 4 weeks, and histological changes were analyzed by Hematoxylin-Eosin staining and Safranin-O staining. In addition, inflammatory cytokines such as TNF-α, IL-1β, and IL-6, and MMP-13, TIMP-1, and GAGs were immunohistochemically analyzed. Finally, hematological examination, blood biochemical examination, and liver and kidney biopsy were performed. Results : SHG groups (Low and High) inhibited the matrix destruction and damage of the knee joint cartilage in SD rat model, and significantly prevented the reduction in cartilage thickness. In SHG groups, the expressions of TNF-α, IL-1β, IL-6 and MMP-13 were significantly decreased, and the expressions of TIMP-1, GAGs were significantly increased compared with OA group. The safety indicators had no significant differences among five groups. Conclusions : These results show that SHG has cartilage protection capacity, anti-inflammatory effect.
The stems of Dendrobium moniliforme are used in traditional Oriental medicine as a Yin tonic to nourish the stomach, promote the production of body fluid, and reduce fever. This study investigated the effects of the aqueous extract of D. moniliforme stems (DME) on mast cell degranulation and the expression of tumor necrosis factor-α (TNF-α), interleukin-4 (IL-4), and histamine-synthesizing enzyme histidine decarboxylase (HDC). We used rat mast cell line RBL-2H3 cells and stimulated them with PMA plus calcium ionophore (PMACI). Pretreatment with DME significantly inhibited PMACI-induced β-hexosaminidase release and the expression of TNF-α, IL-4, and HDC. Furthermore, DME suppressed PMACI-induced nuclear translocation of the nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) and activator protein 1 (AP-1). In addition, HDC expression was inhibited by SP600125 (JNK inhibitor), PD98059 (ERK inhibitor), and SB203580 (p38 kinase inhibitor). Finally, the phosphorylation of p38 kinase, extracellular signal-regulated kinase 1/2 (ERK1/2), and c-Jun N-terminal kinase (JNK) was inhibited by pretreatment with DME. These results suggest that DME has inhibitory effects against degranulation, cytokine (TNF-α and IL-4) and HDC expression, and that HDC expression is mediated by MAPK signaling. These findings suggest that DME may have therapeutic potential in the treatment of hypersensitive and inflammatory diseases.
Purpose: This study evaluates the potential protective effects of hemp (Cannabis sativa L.) seed oil supplementation in rats fed a high-cholesterol diet. Methods: Rats were fed a 1.25% cholesterol diet for 8 weeks, followed by oral administration of either of the two doses of hemp seed oil (HO) (0.5 mL/kg (HOL group) or 1 mL/kg (HOH group) body weight/day) or simvastatin at 10 mg/kg body weight/day. Oxidative stress, lipids, liver enzymes, and renal markers were measured in the serum. Western blot analysis was applied for evaluating the expressions of inflammatory makers. Results: Except for HDL-cholesterol, the altered levels of lipoproteins, aminotransferases, urea, and creatine kinases in hypercholesterolemic rats were significantly corrected by HO administration. Especially, compared to the HOH group, HOL treatment further reduced AST, ALT, creatinine, TC, and LDL-cholesterol levels. Moreover, both the atherogenic index and cardiac risk factor (CRF) in the HOL group were more restrained compared to the HOH group. Increased levels of p-AMPK coincided with the inhibition of SREBP-2 activation which subsequently suppressed the expression of HMGCR. Nuclear factor (NF)-κB activation coincided with the PI3K/Akt pathway activation and the increased phosphorylation of p38; these levels were significantly suppressed by HO treatment. In addition, HO treatment markedly reversed the changes in chemokines such as ICAM-1, VCAM-1, and MCP-1. Histological alterations induced by cholesterol overload in cardiac and hepatic tissues were ameliorated by HO supplementation. Conclusion: Taken together, our results indicate a low concentration of HO demonstrates improved dysfunctions caused by a high-cholesterol diet via inhibition of the PI3K/Akt/NF-κB signaling pathway.
