It studies into viewpoints of 7 doctors of Wenbing studies on macula. The results concerning characteristics, remedy and prevention of macula are as follows; Macule does not protrude on the surface of skin and does not have any color change for external stimulus, but rash out on the surface and becomes white when pushed. It becomes macule when the blood leaks beneath skin as stomach-heat of yangming enters into blood system and damages it. On the other hand, when heat enters lung meridian, penetrates beneath the skin and congeals inside the vessel, it becomes rash. When you combine symptoms of body and pulse with numbers, color, shape and distribution status of macula, you can diagnose the depth of rash, seriousness, the possibility of treatment and prognosis of macula. The remedy for macule consists of cooling heat of yaming, removing heat from the blood and relieving feverish rash, and the one for rash consists of facilitating meridian with aroma, expelling pathogenic factors from muscles with drugs of pungent flavor and cool nature and clearing away heat from the blood systems. It relieves the inhibited functional activities of lung-Ki, and helps extermination of rash as well as clearing heat of the vessel. Also, it is the most important to preserve resin of stomach for every treatment. It is good to avoid expelling pathogenic factors with drugs of pungent flavor and warm nature, raising drugs and invigorating drugs during treating macula. Moreover, the patients should not over dose cold-natured drugs and purgative therapy. There are common clinical symptoms of macula in advance, so right recognition of symptoms can contribute to prevention of macula.

Radiofrequency (RF) radiation might induce the transcription of a certain set of genes as other physical stresses like ionizing radiation and UV. To observe transcriptional changes upon RF radiation, we exposed WI-38, human lung fibroblast cell to 1763 MHz of mobile phone RF radiation at 60 W/kg of specific absorption rate (SAR) for 24h with or without heat control. There were no significant changes in cell numbers and morphology after exposure to RF radiation. Using quantitative RT-PCR, we checked the expression of three heat shock protein (HSP) (HSPA1A, HSPA6 and HSP105) and seven stress-related genes (TNFRSF11B, FGF2, TGFB2, ITGA2, BRIP1, EXO1, and MCM10) in RF only and RF/HS groups of RF-exposed cells. The expressions of three heat shock proteins and seven stress-related genes were selectively changed only in RF/HS groups. Based on the expression of ten genes, we could classify thermal and non-thermal effect of RF-exposure, which genes can be used as biomarkers for RF radiation exposure.

This study was investigated to know the correlation of complete blood count(CBC), biochemical examination and DSOM fluents(Diagnosis System of Oriental Medicine, (C)2005-01-122-004154). There are 5 fluents in DSOM such as DSOM score(病機點數), mean of the index for pathogenic factor(病機指標 平均), 5-division of DSOM score(病機點數 五點尺度), 5-division of the index for pathogenic factor(病機點數 五點尺度), weighted pathogenic factor(病機加重値).We have carried out clinical trials who volunteered for Sasang constitutional medicine and Oriental OB & GY, Oriental Medical hospital of Dong-Eui University, from May 2005 to June 2006. Volunteers were 245 persons. Because 7 persons didn't checkup DSOM, so we analyzed the results statistically for 238 persons. In the relation of CBC and DSOM, the scores(病機點數, zp) and mean of the index for Pathogenic factor(病機指標 平均, zps) showed correlation more frequently, and correlation with results of RBC, hemoglobin, hematocrit was more significant. Correlation with fluents of pathogenic factor(病機) were more significant and high in deficiency of blood(血虛), insufficiency of Yang(陽虛), coldness(寒), damp(濕), dryness(燥), kidney(腎), phlegm(痰), heat syndrom(熱), lung(肺), and was very low in spleen(脾). There was no correlation with deficiency of Yin(陰虛). If volunteers have DSOM fluents, results of RBC and RBC index was decreased(- derection), and results of RDW, ESR was increased(+ direction). But increase and decrease direction in heat syndrom(熱), lung(肺) was contrary to the others. Correlation with fluents of Pathogenic factor(病機) of WBC, platlet, PDW, MPV was not many. In the relation of biochemical examination and DSOM fluents, correlation with results of albumin, uric acid, triglyceride was more significant. If volunteers have fluents of pathogenic factor(病機), result of examination was usually decreased. Especially result of examination was decreased(- derection) highly in deficiency of blood(血虛), stagnation of (氣滯) coldness(寒), dryness(燥), and was increased(+ direction) highly in heat syndrom(熱), lung(肺). But there was a tendency to show high correlation with specific pathogenic factor (病機) and specific examination in biochemical examination.

Objective: This study investigates the expression patterns of toll-like receptors (TLRs) and intracellular mediators in horse muscle cells after exercise, and the relationship between TLRS expression in stressed horse muscle cells and immune cell migration toward them. Methods: The expression patterns of the TLRs (TLR2, TLR4, and TLR8) and downstream signaling pathway-related genes (myeloid differentiation primary response 88 [MYD88]; activating transcription factor 3 [ATF3]) are examined in horse tissues, and horse peripheral blood mononuclear cells (PBMCs), polymorphonuclear cells (PMNs) and muscles in response to exercise, using the quantitative reverse transcription-polymerase chain reaction (qPCR). Expressions of chemokine receptor genes, i.e., C-X-C motif chemokine receptor 2 (CXCR2) and C-C motif chemokine receptor 5 (CCR5), are studied in PBMCs and PMNs. A horse muscle cell line is developed by transfecting SV-T antigen into fetal muscle cells, followed by examination of muscle-specific genes. Horse muscle cells are treated with stressors, i.e., cortisol, hydrogen peroxide (H₂O₂), and heat, to mimic stress conditions in vitro, and the expression of TLR4 and TLR8 are examined in stressed muscle cells, in addition to migration activity of PBMCs toward stressed muscle cells. Results: The qPCR revealed that TLR4 message was expressed in cerebrum, cerebellum, thymus, lung, liver, kidney, and muscle, whereas TLR8 expressed in thymus, lung, and kidney, while TLR2 expressed in thymus, lung, and kidney. Expressions of TLRs, i.e., TLR4 and TLR8, and mediators, i.e., MYD88 and ATF3, were upregulated in muscle, PBMCs and PMNs in response to exercise. Expressions of CXCR2 and CCR5 were also upregulated in PBMCs and PMNs after exercise. In the muscle cell line, TLR4 and TLR8 expressions were upregulated when cells were treated with stressors such as cortisol, H₂O₂, and heat. Migration of PBMCs toward stressed muscle cells was increased by exercise and oxidative stresses, and combinations of these. Treatment with methylsulfonylmethane (MSM), an antioxidant on stressed muscle cells, reduced migration of PBMCs toward stressed muscle cells. Conclusion: In this study, we have successfully cultured horse skeletal muscle cells, isolated horse PBMCs, and established an in vitro system for studying stress-related gene expressions and function. Expression of TLR4, TLR8, CXCR2, and CCR5 in horse muscle cells was higher in response to stressors such as cortisol, H₂O₂, and heat, or combinations of these. In addition, migration of PBMCs toward muscle cells was increased when muscle cells were under stress, but inhibition of reactive oxygen species by MSM modulated migratory activity of PBMCs to stressed muscle cells. Further study is necessary to investigate the biological function(s) of the TLR gene family in horse muscle cells.

Background: The mesenchymal-epithelial transition factor (MET) receptor can be overexpressed in solid tumors, including small cell lung cancer (SCLC). However, the molecular mechanism regulating MET stability and turnover in SCLC remains undefined. One potential mechanism of MET regulation involves the C-terminus of Hsp70-interacting protein (CHIP), which targets heat shock protein 90-interacting proteins for ubiquitination and proteasomal degradation. In the present study, we investigated the functional effects of CHIP expression on MET regulation and the control of SCLC cell apoptosis and invasion. Methods: To evaluate the expression of CHIP and c-Met, which is a protein that in humans is encoded by the MET gene (the MET proto-oncogene), we examined the expression pattern of c-Met and CHIP in SCLC cell lines by western blotting. To investigate whether CHIP overexpression reduced cell proliferation and invasive activity in SCLC cell lines, we transfected cells with CHIP and performed a cell viability assay and cellular apoptosis assays. Results: We found an inverse relationship between the expression of CHIP and MET in SCLC cell lines (n=5). CHIP destabilized the endogenous MET receptor in SCLC cell lines, indicating an essential role for CHIP in the regulation of MET degradation. In addition, CHIP inhibited MET-dependent pathways, and invasion, cell growth, and apoptosis were reduced by CHIP overexpression in SCLC cell lines. Conclusion: C HIP is capable of regulating SCLC cell apoptosis and invasion by inhibiting MET-mediated cytoskeletal and cell survival pathways in NCI-H69 cells. CHIP suppresses MET-dependent signaling, and regulates MET-mediated SCLC motility.

Various efforts have been developed to improve sample preparation steps, which strongly depend on hands-on processes for accurate and sensitive quantitative proteome analysis. In this study, we carried out heating the sample prior to trypsin digestion using an instrument to improve the tryptic digestion process. The heat shock generated by the system efficiently denatured proteins in the sample and increased the reproducibility in quantitative proteomics based on peptide abundance measurements. To demonstrate the effectiveness of the protocol, three cell lines (A human lung cancer cell line (A549), a human embryonic kidney cell line (HEK293T), and a human colorectal cancer cell line (HCT-116)) were selected and the effect of heat shock was compared to that of normal tryptic digestion processes. The tryptic digests were desalted and analysed by LC-MS/MS, the results showed 57 and 36% increase in the number of identified unique peptides and proteins, respectively, than conventional digestion. Heat shock treated samples showed higher numbers of shorter peptides and peptides with low inter-sample variation among triplicate runs. Quantitative LC-MS/MS analysis of heat shock treated sample yielded peptides with smaller relative error percentage for the triplicate run when the peak areas were compared. Exposure of heat-shock to proteomic samples prior to proteolysis in conventional digestion process can increase the digestion efficiency of trypsin resulting in production of increased number of peptides eventually leading to higher proteome coverage.

The epistaxis is commonplace and temporary disease in the field of ENT. In most cases, it is a slight illness, but sometimes, it leads to death because of copious bleeding. The first treatment of epistaxis is stoping hemorrhage, but the real state of treatment in oriental medical is not thoroughgoing enough. So we referred to oriental medical journals and sundry records about etiology and remedy of epistaxis, we got this results. 1. The etiology of epistaxis was mostly bleeding due to heat in the blood by dysfunction of Jang and Bu Gi, there were affection wind-cold by exopathogen, spleen heat to liver, excessive fire of lung meridian, stagnated fire-heat of upper Cho, excessive drinking, bruise and so on. 2. The treatment was used much to remove heat from the blood and activating blood, in case of getting no better, it's used to enriching the blood or clear Gi. 3. The internal remedy of epistaxis was the most used 20times SeogakJihwangtang(犀角地黃湯) to remove heat from the blood and activating blood, and used Jihwangtang(地黃湯), Samhwangbohyultang(三黃補血湯), Jiyuksan(止육散), hueksinsan(黑神散), etc. The drugstuffs were the most used 51times Radix Rehmanniae Preparata((生地黃) to clear heat and remove heat from the blood, produce the body fluids, yin, and used Radix Paeoniae Alba(芍樂) and Radix Glycyrrhizae(甘草), Radix Angelicae Gignatis(當歸), Radix Scutellariae(黃岑), Rhizoma Coptidis(黃連) and Fructus Gardeniae(梔子), etc. 4. The external medical treatment of epistaxis was the most used 16times spraying the granular medication into the cavity and attaching Allii Bulbus(大蒜) to center of the sole or binding the middle finger, etc.

The causes and treatment of alopecia are concluded based on the records found successive oriental medicine in order to persuade new treatments for alopecia as following : 1. In the context of modern medical science male-dominated alopecia was referred as dok-rak(禿落), cho-dok(早禿), chon-dok(全禿), pal-ju-tal-bal, chu-bal-sun and pal-sun(髮癬) alternatively, while alopecia areata was refereed as yu-pung(油風), pan-dok(斑禿), kwi-ji-du and kwi-che-du(鬼剃頭). 2. The causes of alopecia is related with condition of Gi(vital energy) and Hyul(blood) in the twelve channels, such as weakening of vital energy in the conduits, condition of internal organs as heat in the lung, weak kidney or liver vitality, and eating habits such as severe ingestion of bitter taste or sweet taste food. Other distinct reasons are penetration of wind and dryness into a head due to weakening Gi and Hyul inside human body, flaring up of the asthenic fire due to excessive eatings, hard labour or psychological sufferings deficiency of blood, deficiency of vital essence of kidney, phlegm caused by dampness and heat, and stagnated blood. 3. According to demonstration of alopecia, the causes of alopecia areata are listed as internal wind due to heat of blood, deficiency of liver and kidney, blookage of channels and collaterals by stagnated blood, and causes of male-dominated alopecia are listed as wind dryness caused by heat of blood, dampness and heat, and heat, wind and dryness due to deficiency of blood.
