  • The purpose of this study is to investigate the effects of 80% ethanol grape leaf extract (VGLE) and resveratrol (VGLR) from Vitis romaneti on antioxidant of red blood cells (RBC) of rat and efficacy of blood flow improvement in a rat model of topical ferric chloride ($FeCl_3$)-induced carotid artery damage. RBC oxidative hemolysis and plasma lipid peroxidation induced by the aqueous peroxyl radical generator 2,2'-azobis(2-amidinopropane) dihydrochloride were significantly suppressed by VGLE or VGLR in a dose-dependent manner. The $FeCl_3$ treatment seriously damaged the carotid artery: the walls of the artery and blood flow. However, VGLE or VGLR administration has ameliorated the blood flow and suppressed thrombus in blood vessels. These results suggest that VGLE or VGLR ameliorates the oxidative stress of RBC and thrombosis against blood vessel damage.

  • Dendritic cells play an important role in determining whether na${\ddot{i}}$ve T cells mature into either Th1 or Th2 cells. We determined whether heat-shock protein X (HspX) purified from Mycobacterium tuberculosis regulates the Th1/Th2 immune response in an ovalbumin (OVA)-induced murine model of asthma. HspX increased interferon-gamma, IL-17A, -12 and transforming growth factor (TGF)-${\beta}$ production and T-bet gene expression but reduced IL-13 production and GATA-3 gene expression. HspX also inhibited asthmatic reactions as demonstrated by an increase in the number of eosinophils in bronchoalveolar lavage fluid, inflammatory cell infiltration in lung tissues, airway luminal narrowing, and airway hyper-responsiveness. Furthermore, HspX enhanced OVA-induced decrease of regulatory T cells in the mediastinal lymph nodes. This study provides evidence that HspX plays critical roles in the amelioration of asthmatic inflammation in mice. These findings provide new insights into the immunotherapeutic role of HspX with respect to its effects on a murine model of asthma.

  • Purpose : The acupuncture existed more than 2000 years and has flourished not only in Asia but also in medical field of modern world. In addition, empirical evidences from biomedicine have been expended in many ways in order to objectify the field of acupuncture. Thus, the effect and mechanism of the acupuncture has been revealed in human and other animals. In this article, I attempt to explain what doctors and patients subjectively experience through acupuncture treatment and its clinical significance based on mind-body medicine. Methods : The experience and clinical significance of the acupuncture was examined in the view of mind-body medicine, also reviewed research trends related to meditation understanding the clinical effectiveness of acupuncture. Results and Conclusions : Traditional Korean medical doctor perceive generally "jogi " and "chishin " meaning the regulation of the balance of the various functions in the human body and patient's consciousness and psychology state as mightily important concept concerning the therapeutic effect of acupuncture. Despite scientific approach to objective understanding of the acupuncture was performed in the meantime, practitioners put emphasis on experience based on sensate and interaction between doctor-patient. As it reflects the recent understanding of the psychological effects associated with the clinical efficacy of acupuncture, it has been presented one by one through neuroscience and cognitive science. Therefore it is important that interpreting the clinical effectiveness of acupuncture into Mind-body medicine can form a new awareness and attitudes toward traditional medicine.

  • Autophagy plays an important role in cellular homeostasis and survival for cell recycling and various stresses within the cell. Recent studies have shown that autophagy activity modulates the expression of oncogene and tumor suppressor genes, leading to the development or suppression of cancer. Induction of autophagy is involved in preventing cancer development in normal cells and plays an important role in prompting a specific cell death mechanism in cancer cells with damaged cell death function. It is also known that autophagy inhibition increases the therapeutic efficacy by sensitizing cancer cells that are resistant to chemotherapy. However, the role of autophagy has not yet been fully understood in cancer treatment. Oral squamous cell carcinoma accounts for more than 90% of oral cancer and is the sixth most common cancer in the world. The incidence of oral cancer has increased by 50% over the last 20 years and the mortality rate is over 40% within 5 years after the onset. In oral cancers, the role of autophagy are described to look for tumor inhibitory in the early stages of tumor formation, like other cancers, indicating the dual functions involved in tumor cell survival include tumor progression stages. This review summarizes the various roles of autophagy in cancer cells and suggests the possibility of autophagy as a promising target for effective oral cancer therapy.

  • Ferulate is a phenolic compound abundant in wheat germ and bran and has been investigated for its beneficial activities. The aim of the present study is to evaluate the efficacy of ferulate against the oxidative stress-induced imbalance of protein tyrosine kinases (PTKs), protein tyrosine phosphatases (PTPs), and serine/threonine protein phosphatase 2A (PP2A), in connection with our previous finding that oxidative stress-induced imbalance of PTKs and PTPs is linked with proinflammatory nuclear factor-kappa B $(NF-{\kappa}B)$ activation. To test the effects of ferulate on this process, we utilized two oxidative stress-induced inflammatory models. First, YPEN-1 cells were pretreated with ferulate for 1 hr prior to the administration of 2,2'-Azobis(2-methylpropionamidine) dihydrochloride (AAPH). Second, 20-month-old Sprague-Dawley rats were fed ferulate for 10 days. After ferulate treatment, the activities of PTKs, PTPs, and PP2A were measured because these proteins either directly or indirectly promote $NF-{\kappa}B$ activation. Our results revealed that in YPEN-1 cells, ferulate effectively suppressed AAPH-induced increases in reactive oxygen species (ROS) and $NF-{\kappa}B$ activity, as well as AAPH-induced PTK activation. Furthermore, ferulate also inhibited AAPH-induced PTP and PP2A inactivation. In the aged kidney model, ferulate suppressed aging-induced activation of PTKs and ameliorated aging-induced inactivation of PTPs and PP2A. Thus, herein we demonstrated that ferulate could modulate PTK/PTP balance against oxidative stress-induced inactivation of PTPs and PP2A, which is closely linked with $NF-{\kappa}B$ activation. Based on these results, the ability of ferulate to modulate oxidative stress-related inflammatory processes is established, which suggests that this compound could act as a novel therapeutic agent.

  • Objectives : Benign prostatic hyperplasia (BPH) is one of the most common diseases among elderly men. Though medicines such as 5${\alpha}$-reductase inhibitor (finasteride) have recently been developed for treating BPH, their adverse effects and low efficacy should not be overlooked. Curcuma longa has a long history of use in traditional medicines of Asian countries. Many reports conclude the component curcumin in Curcuma lonfa, has the potential to treat various diseases including prostate cancer. In this study, we investigated the therapeutic effects and action mechanism of Curcuma longa with a BPH rat model. Methods : Sprague-Dawley rats were used with subcutaneous injection of testosterone after castration, which were histologically similar to human BPH. A total of 30 rats were equally divided into five groups: Group 1 served as control (sham-operated group): Group 2 was the model group: Group 3 and Group 4 animals were administered Curcuma longa at dose levels of 0.5g/kg and 1.0g/kg: Group 5 served as a positive control group and was treated with finasteride at a dose of 1 mg/kg. The drugs were administered orally once a day for 30 days consecutively. After 31 days, the prostates were removed, and analyzed for their prostatic weight and histological examination. Results : The oral Curcuma longa ingestion group showed statistically significant decreases in their prostatic weights compared with the BPH-induced group and the oral finasteride ingestion group (p<0.05). Curcuma longa is also very safe in liver and kidney up to a dose of lg/kg. Injected testosterone histologically led to prostatic hyperplasia in rats, but oral Curcuma longa ingestion decreased this change. Conclusions : These results suggest that Curcuma longa has a definite inhibitory effect on BPH and might be an alternative medicine for treatment and prevention of human BPH.

  • In our study, osteoporosis was induced by ovariectomized in female rats, and the prevention and treatment efficacy of the climacteric disease the postmenopausal type I pattern was examined by using the experimental substance Cassia tora (CT) ethanol extracts. Female rats were either sham-operated (sham; n=5) or surgically ovariectomized (OVX; five animals per group) and then administered to OVX control, raloxifene hydrochloride (RLX) 1 mg/kg/day, or CT (20 and 200 mg/kg/day) for 12 weeks. Serum osteocalcin and creatinine concentration were significantly lower in the CT 200 mg/kg/day group compared with the OVX control group. Serum progesterone concentration was significantly higher in the CT 200 mg/kg/day group compared with the OVX control group. Reduction grade of the trabecular bone decreased in the RLX 1 and CT 200 mg/kg/day group compared with that of the OVX control group. In conclusion, CT 200 mg/kg/day may have inhibitory effects on osteoporosis in OVX rats.

  • This study was designed to evaluate the clinical efficacy and safety of Rhubarb extracts ($Rubenal^{(R)}$) in dogs with chronic renal failure (CRF). Client-owned 40 dogs with CRF graded International renal interest Society (IRIS) II-III were enrolled in this study. The dogs were equally allocated and blindly administered with $Rubenal^{(R)}$ or placebo. The following items were evaluated at day 0, 30, 90 and 180: body condition score (BCS), clinical score (appetite, polydipsia/polyuria, quality of life score), hemogram (WBC, RBC, PCV), serum biochemistry (ALT/AST, ALP, Creatinine/BUN, total protein, albumin), serum electrolyte (Na, K, Cl, Ca, P), systolic blood pressure, urinalysis (UPC, USG) and IRIS stage. In this study, we found that the $Rubenal^{(R)}$ preparation was well tolerated by dogs and induced no adverse effects. Statistically significant improvements were observed in clinical score (quality of life score by vet and clients), serum BUN and creatinine levels, serum phosphorus concentration, level of proteinuria, and the IRIS score of CRF in dogs after 6 month of treatment of $Rubenal^{(R)}$. Those findings suggested that the Rhubarb extracts can improve the clinical signs of CRF (i.e. azotemia, hypertension, proteinuria, hyperphosphoremia) and the quality of life (i.e. BCS, clinical score) and can retard the progression of CRF in dogs. Therefore the Rhubarb extracts can be a good supplementary drug for treating dogs with subclinical and clinical renal diseases. However, care should be taken for interpreting our result, because this study is not double-blinded controlled study but pilot study.

  • This experiment was conducted to find out the possibility for reducing herbicidal dose of the recommended herbicides in combining with the plant growth regulator "chlorflurenol" at the Yeongnam Crop Experiment Station, from 1981 to 1982. Chlorflurenol itself exhibited weed suppression effect against Monochoria raginalis Presl., Rotala indica Koehne, Cyperus difformis L., Lindernia procrembens Philcox, etc. and its effect increased as the concentrations of chlorflurenol increased from 100 to 1,000 ㎖/㏊. Combination of chlorflurenol with butachlor or thiobencarb, showing synergistic effect, reduced their recommended herbicidal rates by 50 to 75%, showing 90% of weed control rate, stic but combined treatment between chlorflurenol and bentazon showed an antagonistic effect since bentazon had poor control ability to Echinochloa crusgalli Beauv. An application of chlorflurenol showed no significant effect on rice growth, in terms of dry weight, but it resulted in the decrease in the ratio of leaf blade to other non-photosynthetic organ.
