1. As a point at issue of occidental medicine examination, followings have been indicated, 1) Occidental medical examination is performed by mainly test and instrument and therefore, role of doctors could be excluded and it could be diagnosed only for target disease and 2) in Korea, it could not be conducted in public medical system and therefore improvement effect of public health promotion could not be made due to increase of total medical expenses and infirmity of post management. These points are substantial limit of paradigm resided in occidental medicine and also problem caused by unique characteristics of medical system of Korea. In Korea, result of occidental medical examination show increased health risk from aged thirties and major diagnosed diseases are circulatory disease or chronic disease such as hepatic, hyperlipemic, hypertensional disease and diabetes, etc. Accounting that those chronic disease make a role as major public health risk, it is difficult that medical examination by only occidental medicine make effect on public health promotion. 2. Characteristics of oriental medicine examination could be summarized as diagnosis (information acquisition based on the facts) and demonstration (speculation based on acquired information) and in addition, quadruple diagnosis, as a medical examination method, include test as well as basic examination. Accounting on oriental medical examination, principally it is performed by independent herbalist and therefore, herbalist could acquire systemic result during first medical examination. Based on the theory of inner-outer examination, oriental medical examination has a principle of universe theory, systemic analysis of quadruple diagnosis, demonstration & reasoning. In addition, root of oriental medical examination could be found in pre-disease theory, a principal theory of oriental medicine. Pre-disease service could prove the advantage of oriental medicine in medical examination activities and therefore, it is needed that content of oriental medical examination should be actualized in current medical system. 3. In this study, oriental medical examination program, comprised of pulse-diagnosis, contrast muscular taking and medical consultation of herbalist is progressed communally with occidental medical examination. As pre-examination, questionary was given of general characteristics, health promoting life style, physical constitution and subjective symptom of musculoskeletal system. In addition, post-examination notification was given to subjects about health promoting control, physical constitution regimen and management of musculoskeletal system. During this study program, verification was conducted for input of acquired information and difference of each information after analysis and in addition, performed was analysis of factor influencing health promoting life style and musculoskeletal subjective symptom and evaluation of relationship of physical constitution and health promoting life study. In addition, it was verified of difference between musculoskeletal subjective symptom and result of muscle contrast picture evaluation. 4. Evaluation of oriental medical examination model is divided into 2 categories of oriental medical examination-consultation and result evaluation -post management. Oriental medical examination-consultation demands establishment of examination system, standardization of examination and establishment of examination form and in addition, it should be admitted as enlarged examination assists systemic quadruple diagnosis of herbalist not a key of oriental medical examination. In addition, information acquisition for research purpose should be performed according to the systemic research plan based on the separation of questionary for examination purpose and research purpose. For evaluation of the result, it was concluded that needed are result evaluation meets oriental medical system and post-notification system, informing health management information, based on examination result. 5. Accounting on satisfaction for oriental medical examination model, affirmative reply was much higher (66%) than negative (8.64%). Satisfaction of each area was in order of consultation of herbalist, systemic muscle contrast taking, pulse examination, post-notification and questionary fill-up and dissatisfaction was in order of post-notification, questionary fill-up, consultation of herbalist, systemic muscle contrast taking and pulse measurement. Satisfaction for collaborative examination of occidental and oriental medicine was over 60% and over 75% hope oriental examination would be included in later medical examination program. Based on this result, collaborative examination including occidental and oriental medicine could increase satisfaction of subjects for medical examination program.

Enzymatic oxidation of commercially available pyrogallol was efficiently transformed to an oxidative product, purpurogallin. Purpurogallin plays an important role in inhibiting glutathione S-transferase, xanthine oxidase, catechol O-methyltransferase activities and is effective in the cell protection of several cell types. However, the anti-inflammatory functions of purpurogallin are not well studied. Here, we determined the effects of purpurogallin on lipopolysaccharide (LPS)-mediated proinflammatory responses. The results showed that purpurogallin inhibited LPS-mediated barrier hyper-permeability, monocyte adhesion and migration and such inhibitory effects were significantly correlated with the inhibitory functions of purpurogallin on LPS-mediated cell adhesion molecules (vascular cell adhesion molecules, intracellular cell adhesion molecule, E-selectin). Furthermore, LPS-mediated nuclear factor-${\kappa}B$ (NF-${\kappa}B$) and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) releases from HUVECs were inhibited by purpurogallin. Given these results, purpurogallin showed its anti-inflammatory activities and could be a candidate as a therapeutic agent for various systemic inflammatory diseases.

Purpose : Preeclampsia(PE) is a pregnancy-specific disease which is characterized by hypertension and proteinuria. This disease occurs in about 2-8 % of pregnancies in developing countries and remains among the major causes of maternal and neonatal mortality and morbidity throughout the world. Although the causes of PE are not fully understood, the infection has been considered as the main risk factor for this diseases. Periodontal disease may provide a chronic burden of endotoxin and inflammatory cytokines and the disease has been considered as risk factors of systemic illnesses including cardiovascular disease, atherosclerosis, and cerebrovascular ischemia. So, studies performed over the last 15 years have suggested that periodontal disease may be associated with adverse pregnancy outcomes such as PE. However, this association has not been found in all populations. The aim of this review article was to evaluate whether periodontal status and the presence of specific periodontal pathogens may influence the incidence of PE. Methods : Many research articles searched at the electronic databases(MEDLINE; 2000 to July 2017) including search term as periodontal disease and preeclampsia. Result : There were 10 case-control studies and 5 cohort studies meeting our inclusion criteria. The results showed that maternal periodontitis (adjusted odds ratio: 1.5 to 9.3) was associated with preeclampsia in 15 epidemiological studies. Conclusion : It is clear that maternal periodontitis is a risk factor associated with preeclampsia, emphasizing the importance of periodontal care in prenatal programs.

In this study, we aimed to investigate the neuroprotective effects of caffeic acid phenethyl ester (CAPE), an active component of propolis purified from honeybee hives, on photothrombotic cortical ischemic injury in mice. Permanent focal ischemia was achieved in the medial frontal and somatosensory cortices of anesthetized male C57BL/6 mice by irradiation of the skull with cold light laser in combination with systemic administration of rose bengal. The animals were treated with CAPE (0.5-5 mg/kg, i.p.) twice 1 and 6 h after ischemic insult. CAPE significantly reduced the infarct size as well as the expression of tumor necrosis $factor-{\alpha}$, hypoxiainducible $factor-1{\alpha}$ monocyte chemoattractant protein-1, $interleukin-1{\alpha}$, and indoleamine 2,3-dioxygenase in the cerebral cortex ipsilateral to the photothrombosis. Moreover, it induced an increase in heme oxygenase-1 immunoreactivity and interleukin-10 expression. These results suggest that CAPE exerts a remarkable neuroprotective effect on ischemic brain injury via its anti-inflammatory properties, thereby providing a benefit to the therapy of cerebral infarction.

Scrub typhus, caused by Orientia tsutsugamushi infection, is clinically and histopathologically characterized by local as well as systemic inflammatory reactions, indicating that orientiae induce mechanisms that amplify the inflammatory response. To reveal underlying mechanisms of chemoattraction and activation of responding leukocytes, expression of chemokine and tumor necrosis factor alpha (TNF-$\alpha$) genes in murine peritoneal macrophages after infection with the obligate intracellular bacterium Ο.tsutsugamushi was investigated. The genes that were unregulated included macrophage inflammatory proteins l$\alpha$/$\beta$(MIP-l$\alpha$/$\beta$), MIP-2, monocyte chemoattractant protein 1(MCP-1), RANTES (regulated upon activation, normal T-cell expressed and secreted), gamma-interferon-inducible protein 10(IP-10) and TNF-$\alpha$. Peak expression of these chemokines and TNF-$\alpha$ was observed between 1 and 3 h after infection. These responses returned to or approached baseline preinfection levels 6 h after challenge. Semiquantitative reverse transcription (RT)-PCR analysis revealed dramatic Increases during infection in the steady-state levels of mRNA ceding for the inhibitory subunit of NF-kB (IkB$\alpha$), whose transcription is enhanced by binding of NF-kB within the IkB$\alpha$promoter region. Thus, Ο. tsutsugamushi appears to be a stung inducer of chemokines and TNF-$\alpha$ which may significantly contribute to inflammation and tissue damage observed in scrub typhus by attracting and activating phagocytic leukocytes.

Toll-like receptors (TLRs) induce innate immune responses by recognizing conserved microbial structural molecules. All TLR signaling pathways culminate in the activation of nuclear factor kappa-B (NF-$\kappa$B) leading to the induction of inflammatory gene products such as cyclooxygenase-2 (COX-2). Deregulated activation of TLRs can lead to the development of severe systemic inflammation. Divalent heavy metals, cadmium and mercury, have been used for thousands of years. While cadmium and mercury are clearly toxic to most mammalian organ systems, especially the immune system, their underlying toxic mechanism(s) remain unclear. Here, we report biochemical evidence that cadmium, but not mercury, inhibits NF-$\kappa$B activation and COX-2 expression induced by TLR2 or TLR4 agonists, while cadmium does not inhibit NF-$\kappa$B activation induced by the downstream signaling component of TLRs, MyD88. Thus, the target of cadmium to inhibit NF-$\kappa$B activation may be upstream of MyD88 including TLRs themselves, or events leading to TLR activation by agonists.

Chemotherapy is the primary treatment for advanced and recurrent cervical cancer. To evaluate the survival outcomes of chemotherapy and the prognostic factors in this setting, we conducted a retrospective study by reviewing the medical records of advanced and recurrent cervical cancer patients treated with systemic chemotherapy at our institute between January, 2008 and December, 2014. One hundred and seventy-three patients met the criteria with a mean age of 50.9 years. 4.1% of them were HIV positive. The most common initial stage was stage IVB (30.1%) and the most common histology was squamous cell carcinoma (68.6%). Ninety-two (53.2%) patients were previously treated with concurrent chemoradiation with 53% developing combined sites of recurrence. The median recurrence free interval was 16.7 months. Cisplatin + 5 fluorouracil (5FU) (53.2%) was the most frequent first line chemotherapy followed by carboplatin + paclitaxel (20.2%) with an objective response of 39.3%. Seventy-two patients received subsequent chemotherapy. The median overall survival of all studied patients was 13.2 months. Only a recurrence free interval of less than 12 months was an independent prognostic factor for survival outcome. In conclusion, chemotherapy treatment for advanced and recurrent cervical cancer patients showed modest efficacy with a shorter recurrence free survival less than 12 months as a significant poor prognosis factor.

In this study, we investigated the effect of Phellinus baumii (PB) on immediate-type allergic reaction and inflammatory cytokine secretion. PB inhibited compound 48/80-induced systemic reactions in mice. PB inhibited compound 48/80-induced plasma histamine release. In addition, PB also inhibited the immunoglobulin (Ig) E-mediated local allergic reaction. Furthermore, PB decreased the phorbol 12-myristate 13-acetate plus calcium ionophore A23187-stimulated tumor necrosis $factor-\alpha$ and interleukin-6 secretion in human mast cells. These results indicate that PB may be beneficial in the treatment of immediate-type allergic reactions.

Both direct and indirect environmental stress to brain were increase the expression of transcription factor c-fos in various populations of neurons. In this study, we examined whether the intraperitoneal injections of lidocaine at doses inducing convulsion within 10 min increased the level of c-fos mRNA and protein in forebrain areas. In situ hybridization using $[^{35}S]UTP-labeled$ antisense c-fos, cRNA increased c-fos mRNA levels though hippocampal formation, piriform cortex, septum, caudate-putamen, neostriatum, and amygdala within 2 hr. In parallel with the mRNA expression, c-FOS protein immunoreactivity was also observed in the same forebrain areas. In contrast to the seizure activity and widespread neuronal degeneration following a kainate treatment, injections of lidocaine did not produce neuronal death within 3 days. The present study indicates that lidocaine induces convulsion and c-fos expression without causing neurotoxicity.
