Objectives : This study was designed to investigate the anti-obesity effects in local area adipose tissue using by pharmacopuncture of Eriobotryae Folium on mice fed high fat diet. Methods : Male ICR mouse were divided into three groups. Normal diet group (N), High-fat diet(HFD) group, HFD+E(pharmacopuncture of the Eriobotryae Folium) group for 8 weeks. HFD+E group was injected in the concentration of 50 mg/kg once a day for 4 weeks and every other day during the next 4 weeks. We measured body weight, food intake, absolute weight and relative weight in the liver and adipose tissue. Also, we analyzed hematological levels and histopathological changes on adipose tissue. Results : 1. We observed no difference in food intake among three groups. 2. HFD+E group significantly decreased body weight gain and absolute weight and relative weight in the liver and adipose tissue compared with HFD group. 3. Blood AST and ALT were no differences among the experiment groups. However, HFD group was significantly increased higher TG, TC, HDL and LDL than in N group and HDL/LDL ratio was remarkably decreased. On the other hand, HFD+E group was significantly decreased in obesity markers and HDL/LDL ratio was remarkably increased. 4. Levels of adiponectin in serum of HFD+E group was remarkably increased compared with those of HFD group. 5. HFD group was significantly decreased compared with N group in adipocyte number. Compared with the HFD group, HFD+E group was displayed a significant increase by adipocyte number. Conclusions : We suggest that pharmacopuncture of the Leaves of Eriobotrya japonica can play the anti-obesity effects in local area adipose tissue.

Objectives : This study was carried out to investigate the anti-toxicity effect of Hwangryunhaedoktang on the dried Mylabris phalerata extract containing cantharidin in ICR mouse. Methods : Dried Mylabris phalerata extracts were orally administered at dosage level 2000, 1000, 500, 250 and 125mg/kg, respectively with and/or without administration of Hwangryunhaedoktang 200mg/kg. During 2 weeks, the changes of body weight, mortality, $LD_{50}$, macroscopic changes of gastrointestinal tract and liver, changes of serum gastrin and somatostatin levels were observed. Results : Decrease of body weight gains was observed in dried Mylabris phalerata extract-dosing groups, but it was significantly developed in Hwangryunhaedoktang extract-dosing groups after dosaging. Increase of mortality rates was observed in dried Mylabris phalerata extract-dosing groups, but it was significantly developed in Hwangryunhaedoktang extract-dosing groups after dosaging. The $LD_{50}$ of dried Mylabris phalerata extract in male mice significantly increased in a case of concomitant used of Hwangryunhaedoktang 268.86 vs 662.05mg/kg. Clinical signs were observed in dried Mylabris phalerata extract-dosing groups, but it was significantly developed in Hwangryunhaedoktang extract-dosing groups after dosaging after dosaging. Increase of number of hemorrhagic and/or erythematous spots in the gastrointestinal tracts, enlargement and congestion in the liver were observed in dried Mylabris phalerata extract-dosing groups, but it was significantly developed in Hwangryunhaedoktang extract-dosing groups after dosaging. Increase of serum gastrin level was observed in dried Mylarbis phalerata extract-dosing groups, these state of abnormal increase was significantly developed in Hwangryunhaedoktang extract-dosing groups after dosaging. Decrease of serum somatostatin level was observed in dried Mylabris phalerata extract-dosing groups, these state of abnormal decrease was significantly developed in Hwangryunhaedoktang extract-dosing groups after dosaging. Conclusions : We could conclude that the Hwangryunhaedoktang has anti-toxicity effect on the dried Mylabris phalerata extract containing cantharidin.

In this study, the backs with a hair cut of 6-week-old healthy ICR male mice were once exposed to a dose of $400\;mJ/cm^2$ UVB. An acute dermal inflammation was observed, and the certified 100% pure and natural lavender essential oil were applied to the UVB-exposed mice skin twice a day. It was observed that the mice exposed to UVB resulted in an acute inflammation, and when treated with lavender oil the degree of inflammation was much alleviated, and the inflamed skins of both the control and lavender oil-treatment groups were cured almost completely after 6 days of the UVB exposure. At 24 hours after UVB exposure, the epidermal keratinocytes in the control group showed a cell-membrane damage with the destruction of intercellular junctions, agglutination of tonofilaments within the cytoplasm and nucleus damage, while the lavender oil-treatment group had much less cell damage than the control group. While the control group showed a significant increase (p<0.05) in the activity of XO up to 144 hours, the lavender oil-treatment group did not show any significant increase except for 48 hours after the UVB exposure. Both the control and lavender essential oil-treatment groups had a significant decrease in the activities of CAT and SOD up to 96 hours. Particularly, the CAT activity was significantly lower(p<0.05) in the lavender oil-treatment group than the control group up to 48 hours, and higher than the control group at and after 96 hours. The GST activity was significantly decreased in both the control and lavender oil-treatment groups up to 96 hours after the UVB exposure except for the control group at 24 hours, and that of the lavender oil-treatment group was higher than the control group at and after 96 hours. Therefore, it is assumed that the application of the lavender oil to the ultraviolet-damaged mice skin can be effective in treatment for the damaged skin.

Glucosamine (GS) is well known for the treatment of inflammation. However, the mechanism and efficacy of GS for skin inflammation are unclear. The aim of this study was to evaluate the effects and mechanism of GS in the mouse 12-O-tetradecanoyl 13-acetate (TPA)-induced ear edema model. TPA-induced ear edema was evoked in ICR or transglutaminase 2 (Tgase-2) (-/-) mice. GS was administered orally (10-100 mg/kg) or topically (0.5-2.0 w/v %) prior to TPA treatment. Orally administered GS at 10 mg/kg showed a 76 or 57% reduction in ear weight or myeloperoxidase, respectively, and a decreased expression of cyclooxygenase-2 (COX-2), NF-${\kappa}B$ and Tgase-2 in TPA-induced ear edema by western blot and immunohistochemistry. Role of Tgase-2 in TPA ear edema is examined using Tgase-2 (-/-) mice and TPA did not induce COX-2 expression in ear of Tgase-2 (-/-) mice. These observations suggested that Tgase-2 is involved in TPA-induced COX-2 expression in the inflamed ear of mice and antiinflammatory effects of glucosamine is mediated through suppression of Tgase-2 in TPA ear edema.

The safety of a new natural plant composition (ADP) was assessed on the genotoxicity study and 14-day repeat dose toxicity study. ADP contains a mixed water extract obtained from the mixture of Phellodendron cortex (Phellodendron amurense) and Anemarrhena rhizoma (Anemarrhena asphodeloides), and poses the contractile properties mediated by alpha-adrenoceptor of the prostate and urethra as well as antioxidant and anti-inflammatory properties. In order to evaluate genetic safety, in vivo micronucleus test was performed in ICR mice orally administered with three dose levels of 1250, 2500, 5000 mg/kg body weight, and vehicle and positive control. In the 14 days study, Sprague-Dawley rats were treated with ADP at the dose levels of 500, 1000, 2000 mg/kg once a day, and clinical signs, body weights, hematology, serum biochemistry, necropsy findings and organ weights were monitored and examined. In experimental results, ADP treatment, compared with vehicle control, did not induce the micronucleated erythrocytes from mouse bone marrow. In the 14 days study, any significant and toxicological differences in all measurements of parameters were not observed in ADP treatment groups of animals, compared with vehicle treatment. The No-Observed-Adverse-Effect-Level (NOAEL) of ADP in the 14 days study was determined to be greater than 2000 mg/kg/day in both sexes.

Purpose: This study was performed to evaluate anti-thrombotic and anti-inflammatory effects of NeungaSoJeokTang water extract (NSJT). Methods: In the study of anti-inflammatory effects, NSJT was investigated using cultured cells and murine models. As for the parameters of inflammation, levels of several inflammatory cytokines and chemical mediators which are known to be related to inflammation were determined in mouse lung fibroblast cells(mLFC) and RAW 264.7 cells. Results: Prior to the experiment, we evaluated sGOT, sGPT, BUN and creatine after the treatment. As a result, NSJT was innoxious on liver and kidney. In experiment of anti-thrombotic effect, NSJT inhibited the platelet aggregation induced by ADP and epinephrine, and inhibited pulmonary embolism induced by collagen and epinephrine. NSJT did not affect significantly the blood flow rate both in vitro and in vivo. NSJT increased platelet number and fibrinogen amount, and NSJT shortened PT and APTT in thrombus model induced by dextran. In experiment of anti-inflammatory effect, NSJT inhibited $IL-1{\beta}$, IL-6, $TNF-{\alpha}$, COX-2 and NOS-II mRNA expression in a concentration-dependent manner in RAW 264.7 cell line, and inhibited significantly NO production at 50, 100 ${\mu}g/ml$, and also inhibited ROS production in a concentration-dependent manner. NSJT inhibited $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ production significantly in serum of acute inflammation-induced Balb/c mice, and decreased $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ production in spleen tissue, but increased $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ production in liver tissue. NSJT increased survival rate at the 3th day in ICR mice with lethal endotoxemia induced by LPS. Conclusion: These results suggest that NSJT can be used for treating diverse female diseases caused by thrombosis and inflammation such as pelvic pain, pelvic inflammatory disease as well as vulvar pain due to vulvitis, vulvar vestibulitis and so on.

In this study, we evaluated the wound healing rate and, inflammatory cells effects of by Abeliophyllum distichum Nakai (ADN) extract in mice. We also assessed the stability of the ADN extract upon exposure to sunlight. Treatments were as follows: 1) CON (only saline solution), T1 (CON + 0.0125% ADN extract), T2 (CON + 0.05% ADN extract), and T3 (CON + 0.5% ADN extract). A 4 mm punch was used in the central part of the dorsal area to separate it from the subcutaneous tissue, causing a full-thickness skin wound. An amount of 1 mL of each sample was sprayed onto the treatment section of the wound with a pipette every day from the day of wound creation, with proper application ensured using brush. In the stability test, the pH was measured at 1, 4, and 8 weeks after exposing the samples of each treatment section to sunlight considering, the higher concentrations of the ADN extract. The results of this study indicate that the effectiveness of the wound contraction rate in the mice to which the ADN extract was applied was low. Moreover, the stability of the sample containing a high concentration of the ADN extract could not be verified. In addition, no significant results were obtained in the inflammatory reaction assessment. Therefore, additional research focusing on wound contraction, stability, and inflammatory cell outcomes of the ADN extract is needed.

Objectives: We aimed to study the role of vestibular input on spatial memory performance in mice that had undergone bilateral surgical labyrinthectomy, semicircular canal (SCC) occlusion and 4G hypergravity exposure. Methods: Twelve to 16 weeks old ICR mice (n=30) were used for the experiment. The experimental group divided into 3 groups. One group had undergone bilateral chemical labyrinthectomy, and the other group had performed SCC occlusion surgery, and the last group was exposed to 4G hypergravity for 2 weeks. The movement of mice was recorded using camera in Y maze which had 3 radial arms (35 cm long, 7 cm high, 10 cm wide). We counted the number of visiting arms and analyzed the information of arm selection using program we developed before and after procedure. Results: The bilateral labyrinthectomy group which semicircular canal and otolithic function was impaired showed low behavioral performance and spacial memory. The semicircular canal occlusion with $CO_2$ laser group which only semicircular canal function was impaired showed no difference in performance activity and spatial memory. However the hypergravity exposure group in which only otolithic function impaired showed spatial memory function was affected but the behavioral performance was spared. The impairment of spatial memory recovered after a few days after exposure in hypergravity group. Conclusions: This spatial memory function was affected by bilateral vestibular loss. Space-related information processing seems to be determined by otolithic organ information rather than semicircular canals. Due to otolithic function impairment, spatial learning was impaired after exposure to gravity changes in animals and this impaired performance was compensated after normal gravity exposure.
