Ulcerative colitis (UC) is a serious gastrointestinal tract disease characterized by recurrent chronic inflammation and mucosal damage of the gastrointestinal tract. The conventional therapies of choice are anti-inflammatory agents, steroids and anti-TNF-${\alpha}$ therapy. However, inherent limitations in these therapies have steered many UC patients to supplement existing therapies with alternative medicinal products. In the current study, we tested the efficacy of Gingko bilola extract (EGb 761) in abating colonic inflammation in a DSS-induced murine model of colitis. C57BL/6 mice were administered 2% DSS in the drinking water for 7 days, then regular water for 7 days, and then 2% DSS for an additional 7 days. EGb 761 (1 mg/dose) was oral gavaged daily for the duration of the experiment. At the termination of the experiment, mice treated with EGb+DSS showed higher body weight, lower spleen weight and longer colon length compared to mice treated with DSS alone. HE-stained colon tissues also exhibited less histologic inflammation in mice treated with EGb+DSS mice compared to mice treated with DSS alone. The serum levels inflammatory cytokines, KC and TNF-${\alpha}$, were also decreased in mice treated with EGb+DSS compared to mice treated with DSS alone. Finally, addition of EGb 761 to TNF-${\alpha}$ treated colonic cell line (HT29/c1) decreased secretion of IL-8 in vitro. These results collectively suggest that EGb 761 abates induction of colitis in DSS-induced model of colitis in mice.

Objectives : To research the trend of the study related to Chuna(推拿) and to establish the direction of further studies into the Chuna(推拿). Methods : We reviewed and analyzed all theses published by Korean research institution. And these theses were classified by research institutions, published year, field of study, subject, research methods, thesis types, illness and symptoms. Results : The following results were obtained in this study. 1. Classified by the major field of study, oriental medicine accounted for 59 papers, followed by 18 in physical education and 2 in the science of nursing and medicine. 2. Upon classifying theses according to research method and thesis types, research related to clinical trial accounted for nearly half of all theses. It was followed by consideration of documents. 3. After 1998 deals with the effects of the Chuna on variable illnesses such as: ossified posterior longitudinal ligament, chronic coccyalgia, entrapment neuropathy, low birth weight infant, Bell's palsy, stress incontinence, paramenia, Parkinson disease, Bertolloti syndrom, TMJ (because of scoliosis) etc. 4. Two most widely cured illnesses using the Chuna therapy are scoliosis and HNP of L-spine. However, when considering the fact that several clinical tests and casuistics did not include research into Lumbago (including HNP of L-spine), it can be concluded that most of the Chuna therapies have been concentrated on Lumbago. Conclusion : As it can be seen in the above results, the possibility of curing illness through Chuna and the usefulness of Chuna have been shown factually and clinically through various consideration of documents, clinical trial & casuistics. Based upon such facts, it is regarded that further scientific research along with additional clinical approaches involving the Chuna should be performed.

Background: Oral physiotherapy or mouth exercise is considered to be an adjunct but mandatory treatment modality for oral submucous fibrosis (OSMF). This study planned to evaluate the clinical efficacy of a newly designed mouth exercising device (MED) in OSMF patients receiving local ointment, intra-lesional drugs and surgical treatment. Materials and Methods: A total of 231 OSMF patients were selected and treated with basic regime including topical corticosteroids, oral antioxidants and the icecream-stick exercise regime and allotted randomly to two equal groups A and B. Group-A patients were additionally given MED. Subgroups A1 and B1 patients with an inter-incisal distance (IID) 20-35mm were not given any additional therapy; subgroup A2 and B2 patients (IID 20-35mm) were treated additionally with intra-lesional injections. Subgroups A3 and B3 with IID<20mm were managed surgically. IID was measured at baseline and at 6 months recall. The change in IID measurements was calculated and statistically analyzed using 2-way ANOVA and Tukeys multiple post hoc analysis. Results: Average improvement in IID after six months of recall visits was observed to be 8.4 mm in subgroup-A1 (n-53) compared to 5.5 mm in B1(n-50) (p<0.01). The IID improvement in subgroup-A2 was found to be 9.3mm (n-46) compared to 5.1 mm in B2 (n-48) (p<0.01). In the surgery group, mouth opening improvement was observed to be 9.6 mm in subgroup A3 (n-18) compared to 4.8 mm for B3 (n-16) (p<0.01). Conclusions: Use of the MED appears to be effective for increasing oral opening in OMSF patients in conjunction with local, injection and/or surgical treatment.

Background: 5-Fluorouracil (5-FU) is the most commonly used drug in colon cancer therapy. However, despite impressive clinical responses initially, development of drug resistance to 5-Fu in human tumor cells is the primary cause of failure of chemotherapy. In this study, we established a 5-Fu-resistant human colon cancer cell line for comparative chemosensitivity studies. Materials and Methods: Real time PCR and Western blotting were used to determine gene expression levels. Cell viability was measured by MTT assay. Glucose uptake was assess using an Amplex Red Glucose/Glucose Oxidase assay kit. Results: We found that 5-Fu resistance was associated with the overexpression of Glut1 in colon cancer cells. 5-Fu treatment at low toxic concentration induced Glut1 expression. At the same time, upregulation of Glut1 was detected in 5-Fu resistant cells when compared with their parental cells. Importantly, inhibition of Glut1 by a specific inhibitor, WZB117, significantly increased the sensitivity of 5-Fu resistant cells to the drug. Conclusions: This study provides novel information for the future development of targeted therapies for the treatment of chemo-resistant colon cancer patients. In particular it demonstrated that Glut1 inhibitors such as WZB117 may be considered an additional treatment options for patients with 5-Fu resistant colon cancers.

Antihypertensive effect of YH 334 was examined in various experimental hypertension rat models and the systemic and regional hymohynamic profiles of the compound were investigated in conscious spontaneously hypertensive rats (SHR). The antiypertensive potensive potency of YH 334 is found to be more than 10 times stronger than that of nitrendipine in the all hypertensive models. The effective doses to lower the initial blood pressure by 20% $(ED_{20})$ of YH334 were 1.4 mg/kg in normotensive rats (NR), 0.7 mglkg in SHR. 0.1 mg/kg in DOCA salt hypertensive rats (DHR) and 0.4 mg/kg in renal hypertensive rats (RHR), and the $ED_{20}$ values of nitrendipine were 15.8 mg/kg in NR, 7.1 mg/kg in SHR, 1.7 mg/kg in DHR and 4.8 mg/kg in RHR. The primary hemodynamic effect hemodynamic profile is similar to that of nitrendipine. Both compounds seem to produce potent antihypertensive effects by lowering peripheral resistance in the skeletal muscles. In the organ bath study using isolated rabbit aorta, YH 334 was found to be a potent voltage dependent calcium channel blocker without significant inhibitory effect on the receptor operated calcium channels like the most of other dihydropyridine type calcium antagonists. Furthermore, YH334 showed acute diuretic and natriuretic effects in conscious SHR, which may render the unnecessary restriction of sodium in the diet of those patients on long term hypertension therapy. This effect would provide an additional benefit to its potent antihypertensive activity.

Early detection of glottic cancer, facilitated by rigid telescopes or flexible fiberoptic laryngoscope in addition to sparse true vocal cord lymphatics, makes this a highly curable tumor in its early stage. Early glottic cancer has a high cure rate with only radiotherapy or conservative surgery. However complications such as mucositis with radiotherapy and voice complications with conservative surgery has raised recent interest in endolaryngeal laser cordectomy. Laser cordectomy can preserve phonatory function and avoid the complications such as mucositis of radiotherapy. To determine the effectiveness of laser cordectomy, the authors made a two year retrospective study of 23 early glottic cancer cases. Fourteen cases(60.9%) who underwent 1 to 3 endoscopic laser cordectomy with KTP-532 laser were cured with this procedure alone. Seven cases needed an additional radiotherapy and three cases needed therapy with salvage operation. We conclude that the endoscopic laser surgery is a good strategy for the properly selected glottic cancer.

Objectives : Burning mouth syndrome (BMS) is characterized by chronic pain or a burning sensation in the mouth. There is limited evidence available to provide clear guidelines for treating BMS patients and a variety of different treatments have been used. This study was designed to investigate the Effects of Korean medicine therapies on oral pain in patients with BMS. Methods : We surveyed 30 BMS patients who newly visited the Oral Diseases Clinic in the Kyung Hee University Korean Medicine Hospital from February 2012 to March 2013. When the patients visited the clinic for the first time, they were evaluated on sociodemographic characteristics, BMS questionnaire, severity of pain using visual analogue scale (VAS) and pressure pain threshold (PPT) of the acupuncture point CV17. After 3 weeks of Korean medicine therapies (acupuncture, electroacupuncture, pharmacopuncture and herbal medicine), they were re-evaluated with the VAS and the PPT. Results : After 3 weeks of Korean medicine therapies, 30 patients' oral pain improved and the PPT score on CV17 rose, which means decrease of qi-stagnation score. Conclusions : Korean medicine therapies were effective on oral pain in patients with BMS. To confirm the additional curative effect and evaluate the efficacy of each treatment, well-designed randomized controlled trials will be needed in the future.

Objectives: This study is an overview of the meta-analysis and systematic review of randomized controlled trials investigating the clinical effectiveness and safety of pharmacopuncture for patients with stroke. Methods: Core electronic databases were searched from their inception to 21 May 2019. A measurement tool to assess systematic reviews (AMSTAR 2) was applied to screen high-quality studies. The results of these studies were summarized, and additional meta-analysis was conducted. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) was used to evaluate the certainty of evidence. Results: Sixteen studies met eligibility criteria. Four were excluded owing to insufficiency of AMSTAR 2 or low data reliability. The finally selected 12 studies were about pharmacopuncture using either a single herb extract, such as Dengzhan xixin, Sanch, Ginkgo biloba, or Acanthopanax, or a mixture of herbs, such as Compound danshen, Shenxiong, Xingnaojing, or Mailuoning. Most of the patients were from China, with acute ischemic stroke. All the studies using a pharmacopuncture versus a non-pharmacopuncture design reported the significant superiority of pharmacopuncture on every outcome measure. On the other hand, in a few studies, pharmacopuncture was inferior to active control in improving neurological deficit. Few studies reported adverse events. Conclusions: It is difficult to apply the results of this study directly to Korea, because the level of evidence is generally low and the clinical settings and social acceptance of pharmacopuncture therapy differ in Korea and China. Further studies are warranted to confirm the domestic applicability of evidence generated in China and to create evidence that supports the domestic situation.

The purpose of this study was to investigate the toxicity of hematoporphyrin-coated magnetic ferrofluid (HP-MF) through intravenous administration in Sprague-Dawley rats. Each group was treated with either saline, or the HP-MF at 0.5, 1, 1.5, 2 and 4 ml/kg body weight (b.w.) for the observation of survival rate, clinical symptoms, laboratory values and histopathological findings. In this study, HP-MF was evaluated for the survival rates, symptoms, laboratory values and histopathological examination after treatments. The result revealed that the animals in the group of HP-MF at 2 and 4 ml/kg b.w. showed some lethality. In serum biochemistry, the levels of AST, ALT and ALP were increased in the MF and HP-MF treated groups. However, histopathological examination for the suspected organs showed no evidence of hepatotoxicity and nephrotoxicity of typical iron poisoning. Though the toxicity of HP-MF was higher than that of HP, long retention of hematoporphyrin via HP-MF provides additional benefit over conventional hematoporphyrin. HP-MF could be utilized as a potential photodynamic agent in cancer therapy. It is suggested to develop an efficient external magnetic device to attract hematoporphyrin in the target site, thereby enabling to administering a small amount of HP-MF.
