  • Objectives : We investigated the effects of gambigyeongsinhwan(GGH)(1) on body weight and non-alcoholic fatty liver disease(NAFLD) examined whether blood total cholesterol, LDL-cholesterol, free fatty acid and triglyceride levels and hepatic lipid accumulation are inhibited by it in high fat diet-fed obese male mice. Methods : 8 weeks old, high fat diet-fed obese male mice were divided into 5 groups: C57BL/6N normal, control, GGH(1)-1, GGH(1)-2 and GGH(1)-3. After mice were treated with GGH(1) for 8 weeks, we measured body weight gain, food intake, feeding efficiency ratio, fat weight, plasma ALT, leptin and lipid levels. We also did histological analysis for liver and fat on the mice. Results : Compared with controls, GGH(1)-treated mice had lower body weight gain and adipose tissue weight, the magnitudes of which were prominent in GGH(1)-3. Compared with controls, GGH(1)-treated mice had lower feeding efficiency ratio and blood leptin level, the magnitudes of which was prominent in GGH(1)-3. Compared with controls, GGH(1)-treated mice had lower blood plasma total cholesterol, LDL-cholesterol, free fatty acid and triglyceride levels. Compared with controls, GGH(1)-3 treated mice had lower blood plasma ALT concentration. Consistent with their effects on body weight gain, the size of adipocytes were significantly decreased by GGH(1), whereas the adipocyte number per unit area was significantly increased, suggesting that GGH(1) decreased the number of large adipocytes. Hepatic lipid accumulation was decreased by GGH(1). Conclusions : In conclusion, these results suggest that GGH(1) exhibits anti-obesity effects through the modulation of feeding efficiency ratio and plasma obesity parameters. Moreover, it seems that GGH(1) also contributes to improve NAFLD through the regulation of plasma ALT and hepatic triglyceride accumulation.

  • Objectives : The aim of this study was to investigate the protective effect of extract of Thuja orientalis leaves (TOFE) against 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced neurotoxicity by inhibition of inflammation in in vitro and in vivo models of Parkinson's disease (PD). Methods : We evaluated the effect of TOFE against lipopolysaccharide (LPS)/1-methyl-4-phenylpyridinium ($MPP^+$) toxicity using nitric oxide (NO) assay, inducible NO synthase and cyclooxygenase 2 western blot, tyrosine hydroxylase and microglia activation immunohistochemistry (IHC) in BV2 cell, primary rat mesencephalic neurons, or C57BL/6 mice. We also evaluated the effect of TOFE in mice PD model induced by MPTP. C57BL/6 mice were treated with TOFE 50 mg/kg for 5 days and were injected intraperitoneally with four administrations of MPTP on the last day. We conducted behavioral tests and IHC analysis to see how TOFE affect MPTP-induced neuronal loss of dopaminergic neurons in substantia nigra pars compacta (SNpc) and striatum (ST) of mice. To assess the anti-inflammation effects, we carried out glial fibrillary acidic protein and macrophage-1 antigen integrin alpha M in IHC in SNpc and ST of mice. Results : In an in vitro system, TOFE decreasesd NO generations in BV2 cells. TOFE protected dopaminergic cells against LPS or $MPP^+$-induced toxicity in primary mesencephalic dopaminergic neurons. In vivo system, TOFE at 50 mg/kg treated group showed improved motor deteriorations than the MPTP only treated group and TOFE significantly protected striatal dopaminergic damage from MPTP-induced neurotoxicity in mice. Moreover, TOFE inhibited activation of astrocyte and microglia in SNpc and ST of the mice. Conclusions : We concluded that TOFE showed anti-parkinsonian effect by protection of dopaminergic neurons against MPTP toxicity through anti-inflammatory actions.

  • Objectives : Osteoarthritis is characterized by degeneration of articular cartilage, which is characterized by chronic pain, stiffness and decrease range of motion. The present study was designed to compare the therapeutic effect of Dioscoreae Rhizoma water extract (DRW) and Dioscoreae Rhizoma 30% ethanol extract (DRE) on the monosodium iodoacetate (MIA)-induced osteoarthritis rats. Methods : Osteoarthritis was induced by injection of MIA ($50{\mu}{\ell}$ with $80mg/m{\ell}$) into the knee joint cavity of rats. After adaptation period for seven days, rats were divided by 5 groups (n=10/group): normal group, control group, positive control (indomethacin 5 mg/kg), DRW 200 mg/kg treated group, DRE 200 mg/kg treated group (n=10/group). The hind paw weight distribution was measured with the changes of reactive oxygen species (ROS), peroxynitrite ($ONOO^-$) in articulation tissue. Also, the cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), tumor necrosis factoralpha ($TNF{\alpha}$), interleukin-6 (IL-6), matrix metalloproteinase-1 (MMP-1), and tissue inhibitor of metalloproteinases-1 (TIMP-1) were investigated by western blot analysis. Results : The administration of DRW and DRE significantly decreased the hind paw weight distribution. The ROS and $ONOO^-$ levels of cartilaginous tissue were significantly decreased in DRW and DRE compared to control group. The results showed that DRE decreased inflammatory cytokines such as iNOS and $TNF{\alpha}$. Also DRE decreased MMP-1 and increased TIMP-1. Conclusions : Based on the above results, Dioscoreae Rhizoma extract seems to have the therapeutic effect on osteoarthritis via suppression of inflammation.

  • Objectives : This study aimed to investigate the anti-ulcer effect of an standardized herbal extracts mixture of Inulae Flos and Paeoniae Radix (HT074) on acidified ethanol induced gastric injury and its potential mechanisms. Methods : Antioxidant activities of HT074 and its constituents were measured by DPPH (2,2-Diphenyl-1-picrylhydrazyl) and ABTS (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging capacity. After the oral administration of HT074 at doses of 100, 300 mg/kg twice per day for 14 days, Gastric lesions were induced by oral administration of acidified ethanol in Sprague Dawley rats. Oxidative stress markers, such as super oxide dismutase (SOD) activity, concentrations of catalase (CAT) and glutathione (GSH) were measured in gastric mucosal tissues. Additionally, the expression of human mucin gene, Mucin 5AC (MUC5AC) mRNA in gastric mucosal tissues was measured. Results : HT074 showed dose dependent radical scavenging activities against DPPH and ABTS radicals. Oral administration of HT074 300 mg/kg for 14 consecutive days significantly decreased gastric lesions and histological damages induced by HCl/EtOH in rats. HT074 treatment significantly increased the activity of SOD (300 mg/kg) and concentration of GSH (100 and 300 mg/kg), however catalase concentration was not significantly increased. MUC5AC mRNA expression was significantly increased by HT074 100, 300 mg/kg treatment. Conclusions : HT074 protects the gastric mucosa from oxidative stress caused by acidified ethanol by increasing the activity of SOD, concentration of GSH and mucin biosynthesis. These findings suggest that HT074 could be an effective candidate for prevention and treatment of gastritis and gastric ulcer.

  • Objectives : The aim of this study was to investigate the protective effects of an aqueous extract from Taxillus chinensis (DC.) Danser (TCE) in Monosodium iodoacetate (MIA)-induced osteoarthritis (OA) rat model. Methods : Sprague Dawley male rats were divided into the following four groups (n=6 per group): Normal (saline control), MIA (MIA-induced OA with vehicle), TCE (MIA-induced with TCE treatment), and IM (MIA-induced with indomethacin treatment). Rats in which OA was induced by MIA were treated with TCE (200 mg/kg) or indomethacin (1 mg/kg) for 4 weeks. Weight-bearing on the hind legs and body weights were measured weekly. At the end of the experiment (3 weeks after MIA injection), serum aspartate aminotransferase and alanine aminotransferase levels were measured to assess the liver toxicity induced by TCE. Its effects on serum inflammatory cytokine levels and tissue histopathology were also evaluated. Results : TCE restored the hind limb weight-bearing distribution. Serum levels of Interleukin 6 (IL-6), Tumor necrosis factor alpha (TNF-${\alpha}$) and Leukotriene B4 (LTB4) were significantly higher in the MIA group than in the Normal group, but serum IL-6 levels were significantly lower in the TCE group. In the TCE group, the synovial membrane was protected in hematoxylin and eosin and Safranin-O staining, respectively. Conclusions : TCE recovered the hind paw weight bearing distribution, inhibited the production of inflammatory cytokine, and protected synovial tissue and cartilage in the OA rat model. Therefore, TCE appears to be an effective therapeutic agent for treating OA and OA-related symptoms.

  • Objectives : The objective of this study was to investigate the protective effect of Flaxseed oil and Chrysanthemi Indici Flos 50% ethanol extract in an HCl/ethanol induced acute gastritis model. Methods : ICR mice were divided into 6 groups; normal mice (Nor), gastritic mice with distilled water (Veh), gastritic mice with 10 mg/kg sucralfate (SC), gastritic mice with 16 g/㎏ Flaxseed oil (FO), gastritic mice with FO + 50 mg/kg Chrysanthemi Indici Flos (FCL), and gastritic mice with FO + 100 mg/kg Chrysanthemi Indici Flos (FCH). Then, mice were orally administered with 150 mM HCl/60% ethanol and caused acute gastritis. After 1 hr, mice were sacrificed, and blood and stomach tissue were collected. Results : Administration of FCL and FCH to mice prior to the induction of gastritis was found to reduce gastric injury. reactive oxygen species (ROS) and peroxy nitrite ($ONOO^-$) levels of stomach tissues were significantly decreased in FO, FCL, and FCH compared to Veh group. As results of stomach protein analyses, FCL and FCH effectively reduce inflammatory-related factors such as inducible nitric oxide synthase (iNOS), interleukin-6 (IL-6), and interleukin 1 beta ($IL-1{\beta}$) in gastric lesion mice. In addition, nuclear factor kappa B p65 ($NF-{\kappa}B$ p65) and phosphorylation inhibitor of nuclear factor kappa $B{\alpha}(p-I{\kappa}B{\alpha})$ were down-regulated in FCL and FCH administrated gastric lesion mice. Conclusions : These results suggest that FCL and FCH has an inhibitory effect against gastric injury. Therefore, FCL and FCH has the potential to be used as a natural therapeutic drug.

  • Objectives : In present study, we investigated a therapeutic effect and optimum dose of Socheongryong-Tang (SCT) on LPS-induced lung inflammation rats model. Methods : Male Sprague-Dawley rats ($260{\pm}10g$) were divided into 12 groups : Group 1 included the normal rats, and Group 2-12 were administrated LPS by intranasal injection to induce experimental lung inflammation. After 1 day of LPS administration, Group 3-9 were treated with SCT ${\times}1/4$, ${\times}1/2$, ${\times}1$, ${\times}3$, ${\times}6$, ${\times}12$ or ${\times}18$, respectively. Group 10-12 (positive control) were treated with dexamethasone 1 mg/kg or acetylcystein 1.5 mg/kg or diclofenac sodium 0.4 mg/kg, respectively. After sacrifice, bronchoalveolar lavage fluid (BALF) was isolated. The levels of IL-$1{\beta}$, TNF-${\alpha}$, mucin glycoprotein 5AC (MUG5AC) were measured in BALF using enzyme-linked immunosorbent assay (ELISA). Results : LPS injected rats exhibited outstanding lung inflammation manifestations, including increased amount of total cells and neutrophil, and upregulated inflammatory cytokines level in BALF. However, the administration of SCT ${\times}1/4$, ${\times}1/2$ and ${\times}1$ decreased total cells and neutrophil, and suppressed the production of inflammatory cytokines, including $IL-1{\beta}$ and TNF-${\alpha}$, and MUG5AC in BALF. Notably, inhibitory effect of SCT ${\times}1/2$ and ${\times}1$ on the level of TNF-${\alpha}$ was markedly better than that of positive controls, dexamethasone and acetylcystein. Conclusions : Taken together, these results suggest that SCT ${\times}1/2$ and ${\times}1$ has therapeutic effects on LPS-induced lung inflammation rats model.

  • Objectives : The aim of this study was to investigate whether the extract of Coptidis Rhizoma inhibits inflammation in chronic cold stress (CCS)-exposed mice or not. Methods : Coptidis Rhizoma extract (CRE) was made by reflux with distilled water. Male ICR mice (7 weeks old) were divided randomly into 5 groups: (1) control, (2) CCS, (3) CCS+CRE 100 mg/kg, (4) CCS+CRE 300 mg/kg, (5) CCS+CRE 1,000 mg/kg groups. Mice were orally administered once a day for 14 days starting from 1 day before CCS. Group (2)-(5) were exposed to CCS conditions that maintained at $4^{\circ}C$ for 2 h once a day for 14 days. The levels of serum cortisol and hypothalamic prostaglandin E1 (PGE1) and PGE2 were measured by enzyme-linked immunosorbent assay kit. The expression levels of several pro-inflammatory factors like heat shock protein 70 (HSP70), c-fos, and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kB) were measured by western blot analysis in mouse hypothalamus. Results : Oral administration of CRE 1,000 mg/kg significantly suppressed the increase of serum cortisol levels in mice exposed to CCS. CCS-exposed mice had significantly increased the expression of HSP70, c-fos, and NF-kB in hypothalamus, while CRE treatment significantly attenuated the elevation of these pro-inflammatory factors. The ratio of PGE2/PGE1 was also higher in CCS-exposed mice than control group. CRE treatment significantly reduced the increase of PGE2/PGE1 ratio induced by CCS. Conclusion : These findings suggest that Coptidis Rhizoma may work as a potential agent to modulate inflammatory responses under the condition of cold adaptation formed by CCS.

  • Objective : Gastritis is a major complication of gastrointestinal disease. Lonicera japonica is used in folk medicine to treat different diseases such as exopathogenic wind-heat, epidemic febrile diseases, sores, carbuncles and some infectious diseases. Therefore, this study examined the effects of Lonicera japonica water extract (LJE) on HCl/ethano-linduced acute gastric ulceration and anti-oxidants properties. Methods : LC-ESI-IT-TOF MS was employed for rapid identification of major compound from LJE. The antioxidant activities were evaluated through total polyphenol and flavonoid contents and radical scavenging assays and superoxide dismutase (SOD)-like activity. SD rats were randomly divided into five different groups including the normal group, ulcer group, positive group (20 kg/mg of omeprazole, ip), and experimental groups (100 kg/mg and 500 kg/mg of LJE, ip). Results : 4,5-Dicaffeoyl quinic acid, loganic acid, secologanic acid, sweroside, loganin, vogeloside were identified based on the detection of the molecular ion with those of literature data. The LJE was possessed free radical scavenging activities such as DPPH (IC50=189.7 ㎍/㎖), ABTS (IC50=164.5 ㎍/㎖), and SOD-like activity (IC50=405.02 ㎍/㎖). Macroscopic and histological analyses showed LJE treated group were significantly reduced to an extent that it allowed leukocytes penetration of the gastric walls compared with the ulcer group. In addition, an ulcer inhibition rate and prostaglandin E2 levels were increased in rats treated with LJE. Conclusion : The present study has demonstrated the antioxidantive and gastroprotective effect of LJE, these findings suggested that LJE has the potential for use in treatment of gastric disorders.
