  • We are aim to evaluate antimicrobial effects of the extract of Galla rhois (GR) on the health status and performance of growing and finishing pigs. This study was conducted on the growing and finishing pigs (n = 200) for 130 days in a swine husbandry. The animals were divided with two groups; GR treated group (n = 100) and commercial diet feeding group (n = 100). GR treated animals had provided with commercial diet adding the extract of GR as 0.2%. During the study period, we compared clinical signs, weight increase rate, diet consumption amount, fecal scores, gross findings, necropsy findings, histopathological findings between the treated group and non treated group. After necropsy, bacteria isolation and PCR analysis were conducted with the clinical samples. As the results of this long-term clinical trial, GR showed the antimicrobial effects on respiratory disease and diarrhea. We were identified that GR had the anti-bacterial and anti-viral effects.

  • This study was conducted to investigate the ratio and number of the Rhus javanica gall formed by chinese sumac aphid, Scheleechtendalia chinensis, in several different conditions in which R. javanica lives. The density of 11 to 15-year-old R. javanica was more higher and the number of galls was also higher than 1 to 5- or over 16-year-old one at these sites. The formed gall according to four directions such as the East, West, South and North was founded the highest at the East and followed South, North, and West order. The formative rate of R. javanica gall did not differ in the mixture forest, and in the habitat having a heap of a little stone and mosses near a valley was better than in the site of road perimeter. Through an index of the gall diameter and the number of chinese sumac aphid, we evaluated the gall processing and development formed by the aphid. As the density of aphids increase, the size of the gall was also more plumped. The part of phyllotaxy of R. javanica gall in leaf and pinnate of was increased in the middle and upper part of terminal leaflet and leaflet was more occupied than wing. R. javanica which did not form a gall in natural environmental, formed gall by a artificial inoculation of S. chinensis. Some gall disappeared during a gall development from various environmental conditions.

  • We investigated the in vivo effect of an aquous extract from Rhois Galla (R-G) on glucokinase and hexokinase activities of diabetes mellitus induced by interleukin-$1{\beta}$ ($IL-1{\beta}$). After 1 week of alloxan injection, the levels of serum glucose and insulin secretion were dramatically increased, however, the insulin secretion was decreased with administration of R-G. $IL-1{\beta}$ injection allowed the serum glucose level increased and the level was decreased by R-G administration. Furthermore, we could observe that R-G was effective in recovering the levels of insulin secretion. Enzyme activities of the glucokinase and hexokinase were decreased by $IL-1{\beta}$ treatment In contrast, R-G administration to the mice allowed proportion increasing. Seemingly, when $IL-1{\beta}$ was injected to the mice, enzyme activities of the glucokinase and hexokinase were decreased. But, R-G stimulated induction of enzyme activities of the glucokinase and hexokinase as high as normal group. These results suggested that R-G is highly effective in treatment of diabetes mellitus.

  • Antimicrobial activity of Rhus javanica (RJ) extract against animal husbandry disease-related bacteria was determined by a paper disc method. The RJ extracts showed a significant antimicrobial activity against Gram positive (+) bacteria and especially the activity was most potent against L. monocytogenes and S. epidermidis. Minimum inhibitory concentrations (MIC) of the MeOH and EtOH extracts of RJ were in the range of 0.8 ∼ 16 mg/mL and 0.8 ∼ 10 mg/mL, respectively. Furthermore, among five solvent fractions (n-hexane, CHC1$_3$, EtOAc, n-BuOH and $H_2O$ frs.) from MeOH extract of RJ, the EtOAc fr. exhibited the most significant antimicrobial activity The antimicrobial activities of RJ extracts against most microbial strains were unstable by either heat treatment or acid treatment. The inhibitory effect of RJ extracts on microbial cell growth was further examined by the addition of 0, 100, 300, and 500 ppm of RJ extracts into growth medium. The growth of gram positive (+) bacteria, S. aureus, S. epidermidis and L. monocytogenes was inhibited for 72 hours when at least 300 ppm of RJ extracts added, but the growth of gram negative (-) bacteria was only inhibited when at least 500 ppm of RJ extracts were added. Taken together, tile antimicrobial activities of RJ extracts were more effective against gram positive (+) bacteria compared to those against gram negative (-) bacteria.

  • Trafficking process of viral glycoprotein to cell surface results in the syncytium formation when baby hamster kidney (BHK) cells was infected by Newcastle disease virus (NDV). Rhus chinensis gall, well-known as a medicinal plant, inhibited not only syncytium formation, but also trafficking of glycoprotein, hemagglutinin-neuramidase (HN) to the cell-surface. Modification of viral glycoprotein is processed within the endoplasmic reticulum and golgi body during trafficking into surface. R. chinensis gall extracts showed the strong inhibitory activities ($IC_{50}$ $12.5{\mu}g/mL$) against ${\alpha}-glucosidase$, when compared with the ${\beta}-glucosidase$. And this inhibitory activities is increased by the samples in a dose-depedent pattern. These data showed that the extracts of R. chinensis gall inhibited the cell-surface expression of NDV-hemagglutinin-neuramidase glycoprotein without significantly affecting HN glycoprotein synthesis in NDV-infected BHK cells.

  • The extracts from approximately 40 different Korean traditional medicines were prepared to investigate the antimicrobial activities against poultry disease-related bacteria. Among tested, the extracts of Schizandra chinensis (SC), Melia azedarach (MA), Caesalpinia sappan (CS) and Rhus javanica (RJ) exhibited significant antimicrobial activities against Salmonella gallinarum, whereas the extracts of Elsholtzia ciliata (EC), Myristica fragrans (MF), Alpinia katsumadai (AK), Poncirus trifoliata (PT), Prunella vulgaris (PV), CS and RJ exhibited antimicrobial activities against Staphylococcus aureus. Minimum inhibitory concentrations (MIC) of MA, CS and RJ extracts against S. gallinarum were 1.2 mg/ml, whereas MIC of RJ extract for S. aureus was 0.6 ㎎/ml, which was the lowest among tested. The antimicrobial activities of SC and RJ extracts against S. gallinarum were reduced, but those of AK and CS extracts against S. aureus were not affected by heating treatment. The antimicrobial activities of SC extract against S. gallinarum and those of EC, PT and RJ extracts against S. aureus were stable by acid treatment but unstable by alkaline treatment. those of CS extract was not effected by either acid or alkaline treatment. The growth of all bacteria was significantly inhibited within 24 hours by the addition of at least 100 ppm and 300 ppm of RJ and CS extracts, respectively, compared with the control group. In conclusion, these findings suggest that RJ and CS extracts may play important roles for antimicrobial activities against poultry disease-related bacteria.

  • Bacterial fruit blotch (BFB) is one of most important diseases in Cucurbitaceae due to infection of Acidovorax citrulli, causing huge economic losses damage worldwide. This seedborn disease spread rapidly at period of high temperature and humidity. The eco-friendly farming is getting popular. So far there was no effective agent to control BFB in eco-friendly farming. Therefore, effect of the material based on chinese nut-gall extract with antibacterial activity against BFB to was tested against A. citrulli. Different hosts showed various symptoms of BFB. Liquid formulation among exhibited most effective anti-bacterial activity on A. citrulli. Pot experiment in greenhouse showed the potential as an control agent of BFB in cucurbits. The treatment of material based on chinese nut-gall extract showed the positive effect on survival of the watermelon seedling and on the length of the cucumber seedling treated with A. citrulli. We cautiously conclude that the material based on chinese nut-gall extract used in this study may be good agents against major diseases of cucurbits in the future even though it is require to be tested with more study on field test.

  • This study was carried out to develop safe and novel anticoagulation agents from oriental medicinal herbs. From 33 medicinal herbs, 40 different ethanol extracts were prepared according to place of origin or extraction parts, and anticoagulation activities were evaluated by determination of thrombin time (TT), prothrombin time (PT) and activated partial thromboplastin time (aPTT). The average water content and average extraction ratio for the medicinal herbs were $6.85{\pm}2.26%$ and $5.27{\pm}4.25%$, respectively. Evaluation of TT at various concentrations of the extract led to the selection of Mucuna birdwoodiana, Prunus armeniaca, Cacalia ainsliaeiflora, Cinnamonum aromaticum, and Rhus javanica Linneas potent antithrombosis medicinal herbs. Evaluation of PT and aPTT showed that the extracts of R.javanica Linne, M. birdwoodiana, and P. armeniaca have strong anticoagulation activities. Determination of hemolytic activities of 40 different ethanol extracts against human red blood cells, however, showed that only M. birdwoodiana, C. ainsliaeiflora, C. aromaticum, and R. javanica Linnehas strong anticoagulation activity without hemolytic activity at a concentration of 500 mg/ml. Our results suggest that oriental medicinal herbs, which are under a mass-production system, have potentialas a safe and novel source of anticoagulants, as well being a thrombin-specific and coagulation factor-specific inhibitor.
