Objectives This study was carried out to know the effects of Keonbodan (hereinafter referred to KBD) in osteoarthritis induced by Monosodium iodoacetate(hereinafter referred to MIA) on Wistar rat. Methods Osteoarthritis was induced by injection of MIA into left knee joint cavities of rat. Osteoarthritis rats were divided into 4 groups (normal (n=6), control (n=6), indomethacin (n=6), KBD (n=6) group). The control group was administered normal saline and indomethacin group was administered indomethacin (2 mg/kg). And the KBD group was administered KBD (142 mg/kg). Each groups were administered by orally for 4 weeks. This experiment were carried out in vivo. In vivo, at the end of the experiment (5 weeks after MIA injection), effects on hepatotoxicity and nephrotoxicity, cytokines in serum, arachidonic acid, osteocalcin, MMP-9, TIMP-1 and cartilage volume were evaluated. And histopathological examinations on the articular structures of knee joints were performed. Results 1. In weight-bearing measurement, level of weight was increased. 2. In order to hepatotoxicity and nephrotoxicity, ALT, AST, BUN and creatinine were tested. And there were no significant changes. 3. In serum, levels of TNF-$\alpha$, IL-$1{\beta}$ were significantly decreased. IL-6 was insignificantly decreased. 4. In serum, level of MMP-9 and TIMP-1 was decreased. 5. In serum, level of $LTB_4$, $PGE_2$ and osteocalcin was decreased. 6. In ${\mu}$CT-arthrography, the cartilage volume was greater than that of the control group. 7. The joint damage induced by osteoarthritis was lesser than the control group in histopathologic observation (H&E, Safranin-O staining). Conclusions These results demonstrated that KBD suppressed the osteoarthritis- inducing effects of MIA in rat. And further studies are required to find out more effective substance and anti-osteoarthritic mechanism in the future.

Streptococcus mutans (S. mutans) is one of the most important bacteria in the formation of dental plaque and dental caries. S. mutans adheres to an acquired pellicle formed on the tooth surface, and aggregates with many oral bacteria. It initiates plaque formation by synthesizing glucan from sucrose, which is catalyzed by glucosyltransferases. Propolis is a resinous mixture produced by honeybees, by mixing saliva and beeswax with secretions gathered from wood sap and flower pollen. Bees prevent pathogenic invasions by coating the propolis to the outer and inner surface of the honeycomb. Propolis has traditionally been used for the treatment of allergic rhinitis, asthma and dermatitis. We investigated the inhibitory effects of propolis ethanol extract on biofilm formation and gene expression of S. mutans. The biofilm formation of S. mutans was determined by scanning electron microscopy (SEM) and safranin staining. We observed that the extract of propolis had an inhibitory effect on the formation of S. mutans biofilms at concentrations higher than 0.2 mg/ml. Real-time PCR analysis showed that the gene expression of biofilm formation, such as gbpB, spaP, brpA, relA and vicR of S. mutans, was significantly decreased in a dose dependent manner. The ethanol extract of propolis showed concentration dependent growth inhibition of S. mutans, and significant inhibition of acid production at concentrations of 0.025, 0.05, 0.1 and 0.2 mg/ml, compared to the control group. These results suggest that the ethanol extract of propolis inhibits gene expression related to biofilm formation in S. mutans.

Osteoarthritis (OA) is an age-related joint disease characterized by degradation of articular cartilage and its association with chronic pain. Purified Bee venom (PBV) has been traditionally used to the treatment for inflammatory diseases. The purpose of the current study is to examine whether PBV regulates the pro-inflammation against a mouse model of knee OA induced by papain. We studied the effect of PBV on papain-induced OA in the knee joints of mice. Mice were split into following groups: normal control, papain induced OA, OA treated with PBV, OA treated with meloxicam as positive control. Proteoglycan deposition was analyzed by safranin O-fast green staining and H&E staining. Papain injection significantly degraded the proteoglycan in OA mice at 42 days. Cartilage proteoglycan density was significantly higher in PBV treated OA group than those of the positive control groups. These results demonstrate that PBV efficiently suppresses pathological processes in an OA model. Thus, PBV could be a potential therapeutic strategy for the treatment of OA.

Objectives This study was designed to evaluate the anti-inflammatory effects of Seungseup-tang (SST) on the monosodium iodoacetate (MIA)-induced osteoarthritis rats. Methods Osteoarthritis was induced by injection of MIA ($50{\mu}l$ with 80 mg/ml) into knee joint cavity of rats. Rats were divided into 4 groups (normal group, control group, indomethacin treated group, SST treated group, each n=6). Normal group was not injected with MIA and taken normal diet. Control group was injected with MIA and taken with distilled water. Indomethacin treated group was injected with MIA and taken indomethacin 5 mg/kg by oral administration. SST treated group was injected with MIA and taken SST 200 mg/kg by oral administration. We examined the weight-bearing ability of hind paw, biomarkers related to oxidative stress in serum, inflammatory proteins and inflammatory mediators and cytokines. Moreover, histopathological examination of knee joint structure was also performed by Hematoxylin & Eosin (H&E), Safranin-O staining method. Results In the present study, SST treated group showed a similar inhibitory effects alike indomethacin treated group, in most of the studied parameters of inflammation. The increased oxidative stress biomarker such as reactive oxygen species (ROS) and peroxy nitrite ($ONOO^-$) in the serum were reduced with SST. Especially, the level of $ONOO^-$ compared with control group significantly suppressed. Also, the expression of inflammatory mediators and cytokines induced by nuclear factor-kappa B (NF-${\kappa}B$) activation was modulated through inhibition of IkBa phosphorlation. In addition, histological analysis revealed that cartilage damage by MIA repaired markedly in SST treated group. Conclusions According to the results, Seungseup-tang may be effective for preventing the progression of osteoarthritis.

Objectives The aim of this study is to evaluate the fracture healing effect of Jinmu-tang (JM) on femur fractured rats. Methods Rats were randomly divided into 5 groups (normal, control, positive control, JM extract with low concentration and JM extract with high concentration). All group except normal group went through both femur fracture. Normal and control group received no treatment at all. Positive control group were medicated with tramadol (20 mg/kg) once a day for 14 days. Experimental group was orally medicated with JM extract (10 mg/kg for low concentration, 50 mg/kg for high concentration) once a day for 14 days. In order to investigate fracture healing process, plasma and serum were obtained. Also, micro-computed tomography was conducted to see the frature site visually. Immunohistochemistry for transforming growth factor-β1, Ki67, alkaline phosphatase, runt-related transcription factor 2, receptor activator of nuclear factor kappa-β, tartrate resistant acid phosphatase was conducted to observe bone healing progress after 14 days since fracture occured. Aspartate aminotransferase, alanine aminotransferase, blood urea nitrogen and creatinine levels were measured in plasma, for hepatotoxicity and nephrotoxicity of JM extract. Osteocalcin was measured to observe activity of osteoblast. Results Through Micro-CT, more fracture healing was observed on both experimental group than control and positive control group. Through Hematoxylin & Eosin and safranin O staining showed bone cell proliferation and bone formation in the experimental group. RANK was significantly increased in the experimental groups. JM with high concentration showed statistically significant of TGF-β and Osteocalcin. NO, TRAP and ALP were not significantly changed. Liver toxicity was not significantly observed. Creatinine significantly increased in both experimental groups after 28 days. Conclusions As described above, JM extract showed anti-inflammatory effect, promoted fracture healing by stimulating the bone regeneration factor, and showed little hepatotoxicity and nephrotoxicity. In conclusion, JM extract can promote fracture healing and it can be used clinically to patients with fracture.

From the view point of phytopathological anatomy, the author has tried to study the effect of the shoot cluster disease virus on the internal structure of vascular tissues of chinese date tree (Ziziphus jujuba var. inermis Rehd.) comparing healthy checks and diseased plants. The materials were collected at the several sites, Kumgock-Ri, Masuc-Ri, Kyungi-Do, and near the campus of Korea University and around the area of Chongam-Dong, Seoul City, from August 15th to September 5th 1959. The leaf materials of healthy and diseased plants are fixed and aspirated in two kinds of killing solutions, formalin-acetic acid alcohol solution and Craf III solution. Sections were cut at 5-10$\mu$ thickness and stained with the double staining reagents of safranin and fast green. In this experiment the author has observed that there are marked structural changes in the infected plants in contrast of healthy checks. As figures 3-7 show that the following characteric changes have taken place on infected plants: 1) the arrangement of irregularly developed sieve elements in phloem, 2) the degeneration of phloem elements, 3) the irregular arrangement of epidermis in mid-vein, 4) more necrosis is observed among the parenchymatous cells, 5) abundant accumulatin of starch grains in parenchymatous cells, . In contrast to the above irregularities caused by the virus disease, the healthy checks appear normal structures as shown in figures 1 and 2. In adding to the all features noted above, the author could also observe an interesting feature that the xylem elements in mid-vein vascular bundle tissues are considerably disorganized to show the unspecialized vessel elements, the irregularly arranged xylem elements. However, this kind of irregularities which occur in xylem under the virus infection has not been reported previously. The features noted on the internal structure of vascular bundle under the condition of infection by the shoot cluster disease on chinese date trees appear to be more or less closely similar to the symptoms of the bunchy-top of banana and the yellow dwarf disease of barley in respect to the fact that whether phloem necrosis takes place as a primary symptom or a secondary symptom. In all these disease, primary histological changes of hypoplasia and hypertrophy are preceeded by the necrosis of phloem.
