Objectives : Illicium verum Hook. f. has been known to possess antimicrobial, antioxidant, antifungal, anti-inflammatory, insecticidal, analgesic, sedative, convulsive activities, it has been rarely conducted to evaluate the immuno-biological activity. The present study was examined to evaluate the anti-inflammatory effects of the Illicium verum Hook. f. water extracts (IVE) in vivo and in vitro. Methods : Cell viability was measured by MTT assay. The relative levels of NO were measured with Griess reagent. iNOS, COX-2, $NF-{\kappa}B$ and target proteins were detected by immunoblot analysis, and levels of cytokines were analyzed by ELISA kit. Anti-edema effect was determined in the carrageenan (CA)-induced paw edema model in rats. Results : All dosages of IVE used in MTT assay had no significant cytotoxicity. The increases of NO production and iNOS expression were detected in LPS-treated cells compared with control. However, these increases were attenuated by treatment with IVE. Also, IVE reduced the elevated production of $TNF-{\alpha}$, $IL-1{\beta}$ and IL-6 by LPS. IVE inhibited the $p-I{\kappa}B$ and translocation of $NF-{\kappa}B$ to nuclear. Furthermore, IVE significantly inhibited the increases of hind paw swelling, skin thicknesses and inflammatory cell infiltrations induced by CA injection. Therefore, IVE will be favorably inhibited the acute edematous inflammations. Conclusion : These results provide evidences that anti-inflammatory effect of IVE is partly due to the reduction of some inflammatory mediators by suppression of $NF-{\kappa}B$ pathway.
Objective: This study was to investigate the anti-tumor effect, safety, safety, mechanism and metabolizing enzyme of Agrimonia pilosa LEDEB (APL) in female C57B/L mouse tumor (in vivo). Method: First, to evaluate the antitumor activity of APL, we divided the mice into four groups: normal, control, APL50 (50mg/kg), and APL100 (100mg/kg). LLC-obtained American Type Culture Collection was used. LLC had been inoculated to induce tumors. To measure the anti-tumor effect of APL, we calibrated tumor size and weight. To analyze the mechanism of anti-tumor in APL, we used western blotting and to observe metabolizing enzyme in APL we used to real-time PCR. Result: APL50 and APL100 significantly inhibited tumor growth from 12 days after medicine injected. APL did not induce caspase-dependent apoptosis in LLC-bearing mouse tumor. In APL100, it decreased 41% and 71% in CYP2D22 and CYP3A11, respectively. Conclusion: These results suggest that APL has some anti-tumor effects in female C57B/L mouse tumor. APL should be used carefully with other drugs related with CYP2D22 and CYP3A11.
Objectives: This experiment was conducted to examine the toxicity of Water soluble Carthmi-Flos herbal acupuncture (WCF) by administering a single intramuscular dose of WCF in 6-week-old, male and female Sprague-Dawley rats and to find the lethality dose for WCF. Methods: The experiment was conducted at Biotoxtech according to Good Laboratory Practices under a request by the Korean Pharmacopuncture Institute. This experiment was performed based on the testing standards of "Toxicity Test Standards for Drugs" by the Ministry of Food and Drug Safety. Subjects were divided into 4 groups: 1 control group in which normal saline was administered and 3 test groups in which 0.1, 0.5 or 1.0 mL of WCF was administered; a single intramuscular dose was injected into 5 males and 5 females in each group. General symptoms and body weights were observed/measured for 14 days after injection. At the end of the observation period, hematological and clinical chemistry tests were performed, followed by necropsy and histopathological examinations of the injected sections. Results: No mortalities were observed in any group. Also, symptoms, body weight, hematology, clinical chemistry and necropsy were not affected. However, histopathological examination of the injected part in one female in the 1.0-mL group showed infiltration of mononuclear cells and a multi-nucleated giant cell around eosinophilic material. Conclusion: Administration of single intramuscular doses of WCF in 3 groups of rats showed that the approximate lethal dose of WCF for all rats was in excess of 1.0 mL, as no mortalities were observed for injections up to and including 1.0 mL.
This study was performed to produce specific egg yolk antibodies against bovine rotavirus (BRV) and bovine coronavirus (BCV) that are major pathogens causing diarrhea in calves. Chickens were immunized with BRV and BCV intramuscularly in the breast muscle by injection 5 times at two weeks interval. At 6 weeks after the first immunization of BRV or BCV, cross reactivity of each serum derived from BRV- or BCV-immunized hens was tested. Each serum antibody against BRV or BCV was reacted with only specific BRV or BCV antigens. Serum and egg yolk-antibody titers of hens against BRV or BCVwere highest at 8~12 weeks after first immunization. Specific serum and egg yolk-antibody titers against BRV were about 104,000 and 107,000, respectively, and those against BCV were about 145,000 and 155,000, respectively. Hemagglutination inhibition titers in the immunized egg yolk antibodies against BRV and BCV were 5,120 and 1,280, respectively, and were ${\geq}8$ times higher than that in non-immunized control. These results suggested that the immunized egg yolk antibodies could effectively neutralize BRV and BCV.

The role of central adrenergic activity in the genesis of stress ulcers was investigated by intracerebroventricular (i.c.v.) administration of catecholamines and clonidine in pylorus-ligated rats restrained for 4 hours at a temperature of $4^{\circ}C$. 1. The stress-induced ulceration was markedly decreased by the i.c.v. administration of norepinephrine, epinephrine, dopamine or low dose of clonidine. 2. After an i.c.v. administration of norepinephrine or epinephrine, the volume of gastric juice, and both acid and pepsin secretion were markedly decreased. 3. Dopamine or a low dose of clonidne decreased the volume of gastric juice and acid secretion but did not affect pepsin secretion. 4. Isoproterenol caused a decrease in the volume of gastric juice and acid secretion, however, the ulcerogenesis was similar to that of the control. 5. Gastric function as well as ulcerogenesis was little affected by a high dose of clonidine. From the above results, it is suggested that central adrenergic activation inhibits cold-restraint induced ulcerogenesis via adrenergic alpha and dopaminergic receptors, and that this effect may be mediated by a decrease in gastric acid secretion. It is also suggested that other factors may be involved in this antiulcerogenic effect.
This study was carried out to determine the role of cholinoceptors in the ventrolateral medulla on central control of blood pressure (BP) and heart rate (HR). In rats anesthetized with urethane and paralyzed, microinjections of the neuroexcitatory amino acid L-glutamate (300 ng/site) were performed to functionally identity the vasopressor area (VLPA) and the vasodepressor area (VLDA) in the ventrolateral medulla oblongata. 1. The bilateral microinjection of carbachol (300 ng/site) into the VLPA produced significantly an increase in BP and HR which was not blocked by bilateral pretreatment of hexamethoium ($4\;{\mu}g/site$). 2. The bilateral microinjection of physostigmine (200 ng/site) and oxotremorine (300 ng/site) into the VLPA produced significantly an increase in BP respectively. 3. The bilateral microinjection of atropine ($4\;{\mu}g/site$) into the VLPA produced significantly a decrease in BP and HR. 4. The bilateral micro injection of acetylcholine (500 ng/site) and dimethylphenylpiperazinium (500 ng/site) into the VLDA produced significantly a decrease in BP and HR respectively. 5. The depressor and bradycardiac responses elicited by the bilateral microinjection of acetylcholine (500 ng/site) into the VLDA were blocked by bilateral pretreatment of hexamethonium ($4\;{\mu}g/site$). The results suggest that the activation of cholinoceptors in VLPA produce hypertensive and tachycardiac responses which may be mediated by muscarinic receptors, and the activation of cholinoceptors in VLDA produce hypotensive and bradycardiac responses which may be mediated by nicotinic receptors.
This study analyzes correlation between methane gas production and injection of food waste water to motivate to expand renewable energy as a way of GHG (Green House Gas) mitigation to achieve the national GHG target proposed for the climate agreement in Paris last year. Pretreatment of food waste water was processed with pH 6 at $35^{\circ}C$ and used the fixed-bed upflow type reactor with the porous media. As a result of operation of pilot-scaled bioreactor with food waste water, the methane gas production was 6 times higher than the methane gas production of control group with rain water. The average production of methane was $56{\ell}/day/m^3$ which is possible to produce $20m^3$ of methane in $1m^3$ of landfill. As a way of energy source, when it is applied to the landfill over $250,000m^3$, it is also able to achieve financial feasibility along with GHG reduction effect. GHG reductions of $250,000m^3$ scale landfill were assessed by registered CDM project and the annual amount of reductions was 40,000~50,000 $tCO_2e$.

The current studies investigated the therapeutic effects of Ephedra sinica Stapf (ES) herb-acupuncture on the inflammatory responses of rat arthritic joint, which was induced by the intradermal injection of heat-killed Mycobacterium tuberculosis emulsified in squalene to the base of the tail. The measurements of body weight and articular index were exploited as the assessment methods addressing arthritic symptoms, and the expression profiles of cytokines such as TNF-α, IL-1β and IL-6 in the rat joint were analyzed using RT-PCR. The articular indexes of arthritic rats were significantly restored after the treatment with ES herb-acupuncture. Although the clinical symptoms of arthritic rats were apparently alleviated by the ES treatments, their body weights were not recovered. It maybe due to the weight-loss and energy enhancement effects of ES extracts. The expression of TNF-α, IL-1β and IL-6 genes, which were highly stimulated in the knee joints of arthritic rats, were restored to the levels of normal rats after the ES treatment. The therapeutic effect of ES herb-acupuncture was not observed in ES-treated, non-acupoint arthritic group as a sham control. The ES herb-acupuncture into an acupoint ST36 was found to be effective in alleviating the arthritic symptoms in adjuvant-induced arthritis rats as regards the body weight, joint appearance and the expression profiles of inflammatory cytokines.
Jaboyangyeong-hwan (IAE) has been known as a traditional medicine for the treatment of debility, fatigue, and liver diseases. The hepatoprotective effect of the water extract of Jaboyangyeong-hwan was investigated against carbon tetrachloride ($CCl_4$)-induced hepatic damage. A single intraperitoneal injection of $CCl_4$produced liver damage in rats as manifested by the significant rise of aspartate aminotransferase (AST, alanine aminotransferase (ALT), and alkaline phosphatase (ALP) in serum as compared to those of untreated normal group. Pretreatments of rats with the JAE extract (300, 600, and 1200 mg/kg for 7 days) were significantly reduced AST, ALT, and ALP levels compared with $CCl_4$-treated control group. Treatment of rats with $CCl_4$led to significantly increase in lipid peroxidation and significantly decrease in cytochrome P450 and P450 reductase. The oral administration of the JAE extract significantly inhibited the accumulation of microsomal thiobarbituric acid reactive substance (TBARS) and increased the cytochrome P450 and P450 reductase activity. All these biochemical alterations resulting from $CCl_4$administration were inhibited by the pretreatment with JAE extract. These results suggest that JAE water extract can be useful as a hepatoprotective agent.

Acupuncture as a therapeutic intervention is widely used for the treatment of many functional disorders such as substance abuse and mental dysfunction. Clinical trials are currently underway to determine the effectiveness of acupuncture in the treatment of drug addiction. Yet, there are still many unanswered questions about the basic mechanism of acupuncture. Studies have shown that both the psychomotor stimulant effects and rewarding properties of addictive drugs, including morphine, are sensitized by repeated drug administration and raised the possibility that both of these effects may De linked to the same or closely overlapping the mesolimbic dopamine systems. Neiguan (PC6) point on the pericardium channel which is associated with the brain and its mental function, has been used to treat mental, psychosomatic disorders and gastroenterological disorders. The present study was designed to investigate the effect of acupuncture on repeated morphine-induced changes in extracellular dopamine levels using in vivo microdialysis and to measure the effect of acupuncture on repeated morphine-induced behavioral changes. Male Sprague-Dawley rats were treated twice a day for three days with increasing doses of morphine (10, 20 and 40 mg/kg, s.c.) or with saline. After 15 days of withdrawal, rats were challenged with morphine hydrochloride (5 mg/kg, s.c.). Acupuncture was applied at bilateral Neiguan (PC6) points for 1min after the morphine challenge. Results showed that acupuncture at the specific acupoint PC6, but not at control points (tail and HE8) significantly decreased both dopamine release, behavior induced by a systemic morphine challenge or a single s.c. morphine injection in the morphine-repeated animals. These results suggest that reduction in sensitization may be one mechanism whereby acupuncture alleviates morphine craving in addicts. Moreover, in a more general sense these results suggest that acupuncture can be used as a therapeutic intervention for correcting reversible malfunction of the body by direction of brain pathway and thus acupuncture can contribute to the biochemical balance in the central nervous system by regulating neurotransmitters.
