Objectives : Evodia officinalis DODE (EO), an herbal plant, has been widely used in traditional Korean medicine for the treatment of vascular diseases such as hypertension. The crude extract of EO contains phenolic compounds that are effective in protecting liver microsomes, hepatocytes, and erythrocytes against oxidative damage. But EO has been little found to have an anti-inflammatory activity. We investigated anti-inflammatory activity of EO in RAW 264.7 cells and human umbilical vein endothelial cells (HUVECs). Methods : Cytotoxic activity of EO on RAW 264.7 cells was investigated by using 5-(3-caroboxymeth-oxyphenyl)-2H-tetra-zolium inner salt (MTS) assay. The nitric oxide (NO) production was measured by Griess reagent system. And proinflammatory cytokines were measured by ELISA kit. The levels of intracellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) expression were measured by flow cytometer. Results : EO decreased LPS-induced NO production in RAW 264.7 cells. The inhibitory activity of EO on LPS-induced NO release is probably associated with suppressing TNF-${\alpha}$, IL-6 and MCP-1 formation. These results indicate that EO has potential as an anti-inflammatory agent. Moreover, EO decreased TNF-${\alpha}$-induced IL-8, IL-6 production, and ICAM-1 and VCAM-1 expression in HUVECs. Conclusions : EO inhibits TNF-${\alpha}$-induced inflammation via decreasing cytokines production and adhesion molecules expression. These results indicate that EO has potential as an anti-inflammation and anti-artherosclerosis agent.

Background: In a wide range of industries, noise-induced hearing loss remains one of the most prevalent occupational problems. This study aimed to assess the noise exposure level and associated factors of hearing loss among textile workers in Yangon Region, Myanmar. Methods: A cross-sectional study was conducted at a Textile mill (Thamine), Yangon Region, from April to December 2018. In total, 226 workers who were randomly selected from 3 weaving sections participated in face-to-face interviews using a structured questionnaire. A digital sound level meter and pure-tone audiometer were used for the assessment of noise exposure level and hearing loss, respectively. Logistic regression analysis was performed to assess the associated factors of hearing loss. Results: In total workers, 66.4% were exposed to ≥85 dB(A) of noise exposure, and the prevalence of hearing loss was 25.7%. Age ≥35 years, below high school education, hearing difficulty, tinnitus, hypertension, > 9 years of service duration in a textile mill were positively associated with hearing loss. After adjusting confounding factors, age ≥35 years (adjusted odds ratio = 6.90, 95% confidence interval = 3.45-13.82) and tinnitus (adjusted odds ratio = 2.88, 95% confidence interval = 1.13-7.37) were persistently associated with hearing loss. Conclusion: Providing occupational hazard education and enforcement of occupational safety regulations should be taken to decrease the noise exposure level. The regular audiometry test should be conducted for assessment of hearing threshold shift. The employer needs to implement a hearing conservation program in workplace when noise exposure reaches or exceeds 85 dB(A) for 8 hours.

Objectives : Although previous anatomic, physiological and biophysics studies have examined the acupuncture meridian system, much remains unclear and controversial. This study was undertaken to examine electrical potential aspects of the meridian system. Electric potential was measured at the well and sea acupoints on the twelve acupuncture meridians (AM), on forty patients half with loin lesions, and pain of loin and lower extremities(LL) and half with shoulder lesions, and aching of shoulder and arm(SA). The object was to determine to what extent electric potential is an important risk factor between LL and SA. Methods : At the left and the right side with each of twenty LL and twenty SA patients, physiograph was used to measure electric potentials of AM ten sessions. T-test was used to compare the mean of electric potential between the two different pain groups and multiple logistic regression was used to analyze the risk of the 24 electric potentials measured. Results and Conclusions : In the LL, the only electric potential that was statistically significantly greater than SA was the bladder meridian on the left side. On the contrary, electric potentials in SA, which includes the large intestine, pericardium, triple burner, spleen, stomach, kidney and gallbladder meridians, were statistically larger than those of LL at the same side. On the right side, the five kinds of electric potentials(lung, large intestine, small intestine, pericardium and gallbladder meridian) of LL were statistically larger than those of SA. On the triple burner, stomach and kidney meridians electric potentials of SA were larger than those in LL. After adjusting for 24 electric potentials, pain risk factors, and different illness categories, multiple stepwise selection logistic regression modeling, resulted in the final selection of a total of 13 statistically significant electric potentials. These were 7 electric potentials at left side - small intestine, triple burner, spleen, stomach, bladder, liver and gallbladder meridian, and 6 at rght side - lung, large intestine, heart, pericardium, kidney and bladder meridian.

To evaluate the effects of Injinchunggantang-derivative on cell viability, cell cycle progression, and apoptosis, MTT assay, cell cycle analysis, Cpp32 protease assay, DNA fragnemtation assay, quantitative RT-PCR, and Western blotting were performed. The results were as followes. In MTT assay, etoposide+Injinchunggantang-derivative-treated cells as well as Injinchunggantang-derivative-treated cells showed higher viability than etoposide-treated cells with no time-concentration-dependence, which implied that Injinchunggantang-derivative has hepato-protective effect Cell cycle analysis showed that Injinchunggantang-derivative has no significant effect on the cell cycle. Cpp32 protease assav and DNA fragmentation assay Injinchunggantang-derivative carry inhibitory effects on apoptosis induction. It was suggested that Injinchunggantang-delivative might regulate the cell cycle, in particular $G_1$ checkpoint by blocking p53 and Watl pathway. Injinchunggantang-derivative inhibited the mRNA expressions of Cpp32, Fas, and Bcl-2, which could result in inhibition of apoptosis. These results imply that Injinchunggantang-derivative increases hepatocyte viability, and protects hepatocyte from damage by regulating the expression of genes associated with cell cycle and apoptosis, which explains the mechanism of the clinical effect of Injinchunggantang-derivative on liver diseases.

Sophora japonica has been used for treatment of liver and blood-related diseases in herbology. We evaluated whitening activities of Sophorae Flos and Fructus. Sophorae Flos and Fructus were extracted with methanol (MeOH) and divided into petroleum ether, ethyl acetate(EtOAC) and water fraction. For whitening effect by western blot in B16 F10 cells, we analyzed it by investigating the effect of tyrosinase, TRP-l (tyrosinase-related protein 1), TRP-2 (tyrosinase-related protein 2) and MITF (microphthalmia-associated transcription factor) protein expression. The protein expressions of tyrosinase, TRP-1, TRP-2 and MITF in B16 F10 cells treated with Sophorae Flos and Fructus extract were reduced in a dose-dependant manner. Therefore, these results suggest that Sophorae Flos and Fructus have useful plant resource to be developed as functional cosmetic.

Background : The human being and the bacteria have accomplished a balance and have coexisted each other during long time. Probiotics have evolved with the human host to exist and the result they have operated profitably to human host. So it requires that the functions of probiotics are expounded in view of Traditional Korean Medicine. Aim : Suggest the functions of probiotics in view of Traditional Korean Medicine. Method : The author's research has been performed to review the related references. Results : Probiotics assist the absorption of the lactose, proteins and minerals and product several kinds of vitamins, organic acids. Probiotics suppresses the growth of noxious bacteria and the production of harmful substances or gases. They absorbed and discharge the bile acid, and thus help us maintain the optimal level of blood cholesterol concentration. They can reinforce the immune response of the mucous membrane and control the hypersensitivity immune reaction such as asthma, atopy on the other hand. Probiotics have right functions as above and so can be applied widely in treatment of various disease and symptom. Conclusion : Considering the functions of probiotics in view of Traditional Korean Medicine, they participate in our spleen-earth-system (digestion and synthesis) and liver-wood-system (regulation of digestion, metabolism, internal secretion etc.), assist the function of lung-metal system(respiration and regulation of water metabolism) and regulate wi-chi (reinforce/control immune system). Consequently, hereafter there would be a necessity of control a circumstance in treatment of various diseases under these categories that probiotics should be able to do their right functions inside the human body.

Objectives The objective of this study is to develop a taeeumin animal-experimental model induced lung fibrosis with Bleomycin and evaluate the effect on obesity in this animal-experimental model.Methods The subjects were divided into 3 groups : normal group, high fat diet(HFD) control group, and HFD group administered with bleomycin(n=10 per group). To develop taeeumin animal-experimental model with reduced respiratory metabolism, 8-week-old C57BL/6 mice were administered with 0.03ml solution of bleomycin 1U/ml dissolved in distilled water, intratracheal(IT), once. Then, the HFD control group and the experimental group were fed with high fat diet for 6 weeks. Airway hyperresponsiveness(AHR) to methacholine was measured at the 1st and 3rd week after bleomycin was administered. Food intake and body weight were measured at regular time weekly. After the final experiment, blood was gathered by cardiac puncture for bloodchemical examination and organs(liver, fatty tissue) were remoed, weighted, and mRNA was analyzed.Results and Conclusions Through the experiment, it was found that Bleomycin induced Taeeumin animal-experimental models have leptin resistace. In the experimental group administered with Bleomycin, fatty acid synthesizing gene expression increased and energy metabolizing gene expression decreased. As mRNA expression of adiponectin decreased, it was found that Taeeuim animal-experimental model is susceptible to metabolic syndrome and cardiovascular diseases.

This is a retrospective study on emergency patients with active oral bleeding. The study was based on a series of 135 patients treated as emergency patients at Wonju Christian Hospital, from Jan. 1, 1997, to Dec. 31, 2001. The postoperative bleeding was the most frequent cause of active oral bleeding in emergency room and bleeding from trauma and medically compromised (bleeding disorders) patients were next in order of frequency. In the injury of maxillofacial vessels, peak incidence was occurred in the inferior alveolar vessel (42.9%), followed by the submucosal vessel of lip & cheek, the superior alveolar vessel, and sublingual vessels. The most common disease of bleeding disorders was vascular wall alteration (infection, etc), followed by liver disease, thrombocytopenic purpura, anti-coagulation drugs in order. In the characteristics of dental diseases on bleeding disorders, periodontal disease and alveolar osteitis (osteomyelitis) were more common. The hemostasis was most obtained by use of wound suture, simple pressure dressing, drainage for infection control and primary interdental wiring of fracture. In the complication group, the infrequent incidence was showed in vomiting, hypovolemic shock, syncope, recurred bleeding & aspiration pneumonia. In the uncontrolled oral bleeding, the injured vessels were suspected as skull base & ethmoidal vessels. In this study, authors found that the close cooperation between the dentistry (Oral and maxillofacial surgery) and the medicine (emergency & internal medicine) was the most important for early proper control of active oral bleeding. And then post-operative wound closure, drainage for infection control and previous systemic evaluation of bleeding disorders were critical for the prevention of postoperative bleeding in the local dental clinic.

Anoectochilus formosanus, commonly known as "Jewel Orchids", which has been used in traditional folk medicines for feber, pain, and diseases of the lung and liver in Taiwan. We artificially cultured Anoectochilus formosanus plantlet by using the bioreactor culture system for this study from Anoectochilus formosanus. Previously, several studies have been reported on pharmacological activities of lipid-metabolism, hepatoprotective activity, anti-tumor activity and immuno-stimulating effects but other efficacy were not well known as a cosmetic ingredient for skin care. In this study, we investigated the effect of melanogenesis in B16 mouse melanoma cells and lipid droplet accumulation in 3T3-L1 preadipocytes about Anoectochilus formosanus plantlet extract. We report that Anoectochilus formosanus plantlet extract inhibits the cytoplasmic lipid droplet accumulation through adipogenic differentiation of preadipocytes as well as inhibition of tyorsinase activity and melanogenesis. As a result, our findings indicate that Anoectochilus formosanus plantlet extract may be the potential natural ingredient for whitening and slimming cosmetic products.

Monocytoid B-cell lymphoma is uncommon, low grade lymphoma originating from monocytoid B lymphocytes. Monocytoid B-cell lymphoma usually presents as a localized lymphadenopathy. Peripheral lymph nodes are most often involved, particularly those in the frequent in the head and neck area. A distinctive feature is the association of monocytoid B-cell lymphoma with autoimmune diseases. Sjogren Syndrome had been present in 22% of patient with monocytoid lymphoma. Extranodal involvement by monocytoid lymphoma was reported in the salivary gland, breast, thyroid, and stomach. There were also occasional extensions to the liver and retroperitoneum. The bone marrow and peripheral blood involvement by monocytoid lymphoma is very rare, which is frequently seen in hairly cell leukemia. Fever, weight loss, and other constitutional signs are usually absent. Most patients have no symptoms, and the only sign is enlarged lymph nodes. The clinical course remains indolent; most patients are in complete remission and recurrence with progression to a high-grade lymphoma of large cell type was recorded only in a few cases. Authors experienced a case of monocytoid B-cell lymphoma associated with Sjogren Syndrome mistaken to simple cervical lymphadenitis in a 60-year-old female. We report this case with a review of literatures.
