  • This study was to find out whether MBT shoes were more effective than general sporting shoes on the kinematic physiology. We comparatively analyzed energy consumption, heart rates, rating of perceived exertion, lactic acid density in blood and muscle activity with EMG. The subjects were 10 regular students of K Univ.(5 male and 5 female). They wore the general sporting shoes for stage 1(group 1), the MBT walking shoes for stage 2(group2) under the same conditions. There was one week interval between stages. 1. There was no significant difference in the energy consumption and the heart rates between two groups. Group 1 showed a higher energy consumption and heart rates than Group 2 under the speed of 4.0 mph. On the other hand, Group 2 showed higher ones over the speed of 4.0 mph. 2. There was no significant difference in the rating of perceived exertion and lactic acid density in blood between two groups. But Group 2 showed a lower fatigue strength than Group 1. 3. Group 2 showed a higher muscle activity with EMG than group 1, especially at the speed of 2.0, 2.5, 3.0, 3.5 mph in quadratus lumborum muscle and at 4.0mph in tibialis anterior muscle. In conclusion, we are less tired in MBT shoes than in general sporting shoes. Also, we can dorsiflex better in the ankle joint, straighten the lumbar region well and walk erect in MBT shoes. Specially, when it walks slowly, it is favorable in an erection walk and when it walks quickly, we have advantage of obesity management.

  • Polymorphonuclear leukocytes (PMNs) play an important role in myocardial ischemia/reperfusion (MI/R) injury. Moreover, platelets are also important blood cells that can aggravate myocardial ischemic injury. This study was designed to test the effects of PMNs and platelets separately and together in provoking cardiac dysfunction in isolated perfused rat hearts following ischemia and reperfusion. Additional control rat hearts were perfused with $75{\times}10^6$ PMNs, with $75{\times}10^6$ platelets, or with $75{\times}10^6\;PMNs+75{\times}10^6$ platelets over a five minute perfusion followed by a 75 min observation period. No significant reduction in coronary flow (CF), left ventricular developed pressure (LVDP), or the first derivative of LVDP (dP/dt max) was observed at the end of the observation period in any non-ischemic group. Similarly, global ischemia (I) for 20 min followed by 45 minutes of reperfusion (R) produced no sustained effects on the final recovery of any of these parameters in any group of hearts perfused in the absence of blood cells. However, I/R hearts perfused with either PMNs or platelets alone exhibited decreases in these variables of $5{\sim}10%$ (p<0.05 from control). Furthermore, I/R hearts perfused with both PMNs and platelets exhibited decreases of 50 to 60% in all measurements of cardiac function (p<0.01). These dual cell perfused I/R hearts also exhibited marked increases in cardiac myeloperoxidase (MPO) activity indicating a significant PMN infiltration, and enhanced P-selectin expression on the coronary microvascular endothelium. All cardiaodynamic effects as well as PMN accumulation and P-selectin expression were markedly attenuated by a recombinant soluble PSGL-1 which inhibits selectin mediated cell adhesion. These results provide evidence that platelets and PMNs act synergistically in provoking post-reperfusion cardiac dysfunction, and that this may be largely due to cell to cell interactions mediated by P-selectin. These results also demonstrate that a recombinant soluble PSGL-1 reduces myocardial reperfusion injury by platelet and PMNs interaction.

  • Pre-eclampsia (PE) is a pregnancy disorder that is characterised by severe hypertension and increased risks of foetal and maternal mortality. The aetiology of PE not completely understood; however, maternal nutrition and oxidative stress play important roles in the development of hypertension. The treatment options for PE are currently limited to anti-hypertensive drugs. Punicalagin, a polyphenol present in pomegranate juice, has a range of bioactive properties. The effects of supplementation with punicalagin on angiogenesis and oxidative stress in pregnant rats with induced hypertension were investigated. The pregnant rats were randomly divided into five experimental groups (n=12 per group). Hypertension was induced using an oral dose of NG-nitro-L-arginine methyl ester (L-NAME, 50 mg/kg/day) on days 14-19 of pregnancy. Punicalagin (25, 50 or 100 mg/kg) was given orally on days 14-21 of pregnancy. Punicalagin treatment at the tested doses significantly reduced diastolic, systolic, and mean arterial blood pressure in L-NAME treated rats from day 14. Punicalagin also restored angiogenic balance by increasing the expression of vascular endothelial growth factor and downregulating vascular endothelial growth factor receptor-1/fms-like tyrosine kinase-1. Punicalagin, significantly increased the placental nitric oxide levels as compared to PE group. The increased levels of oxidative stress in rats with PE were markedly decreased by treatment with punicalagin. Punicalagin at the tested doses markedly (p<0.05) enhanced the placental antioxidant capacity in L-NAME-treated rats. The raised catalase activity observed following L-NAME induction was significantly (p<0.05) and restored to normal activity levels in punicalagin treatment. Further, 100 mg dose of punicalagin exhibited higher protective effects as compared to lower doses of 25 and 50 mg. This study shows that supplementation with punicalagin decreased blood pressure and oxidative stress and restored angiogenic balance in pregnant rats with induced PE.

  • In this paper, the effect of Ganopoly(extracts of Ganoderma lucidum) and Ganopoly/C+(70% Ganopoly + 30% chitosan) on cisplastin-induced nephrotoxicity was investigated in Sprague-Dawley rats. A single dose of cisplastin(5 ㎎/㎏) kg) was administered intraperitoneally after pretreatment of saline, Ganopoly and Ganopoly/C+ for 7 days. The nephrotoxicity and renal function were manifestated by the changes of body weight, blood pressure, biochemical changes and solute in urine and plasma. After the treatment of CDDP(cis-dichlorodiamineplatinum), a significant elevation of kidney weight, serum urea, cretinine, urine volume for 24 hours, urine magnesium, and a severe or significant decrease in body weight, blood pressure, creatinine clearance, urine osmolarity, serum albumin, etc. The nephrotoxicity was further confirmed by a significant decrease in glutathione S-transferase(GSH) in urine and kidney homogenate, GSH, glutathione peroxidase(GSH-Px) and catalase in kidney tissue. And also the lipid peroxidation was significantly increased in kidney homogenate. These signs of nephrotoxicity was ameliorated by the pretreatment and consecutive administration of Ganopoly and Ganopoly/C+ for 14 days after the Lp. injection of CDDP on 7th day after pretreatment of Ganopoly and Ganopoly/C+. The amelioration of nephrotoxicity was evidenced by significant reduction in serum urea and creatinine concentration, and improvement of other index of renal function. And The activity of antioxidant enzymes were partially recovered in kidney tissue of rats treated by CDDP and the administration of Ganopoly and Ganopoly/C+. These results indicate the cispastin induced nephrotoxicity is due to an impairment of tubular reabsorption systems enhanced by necrosis of proximal tubule, and the Ganopoly and Ganopoly/C+ has a partial protective effect on nephrotoxicity induced by CDDP. The polysacchride of Ganoderma lucidum may improve the therapeutic index of nephrotoxicity induced by CDDP. However, it is needed to elucidate the mechanism for confirming the therapeutic effect.

  • This study was done to examine the risk factors between controls group and acute brain infarction patients group, and to compare high risk group with low risk group through NIHSS(National Institutes of Health stroke scale). We compared the risk factors between acute brain infarction patients group(N=180) and controls group(N=93). And according to risk factors, we analyzed 1st NIHss, after 3 weeks improved extent within acute brain infarction patients group. The results were as follows. 1. Among the risk factors, HTN, DM, the blood levels of HCY were significantly higher and the blood levels of HDL-C was significantly lower in patients group than controls group. 2. In scale analysis according to risk factors, 1st NIHss were significantly higher in Hypo-HDL-cholesterolemia, Obesity, High-Homocysteine, HTN, DM, previous CVA history group than low risk group within acute brain infarction patients group. 3. In after 3 weeks improved extent analysis according to risk factors, improved extent were lower in Hyperlipidemia, HTN, DM, previous cardiac history, older age group than low risk group within acute brain infarction patients group. The above results suggest that significant risk factors of acute brain infarction, and shows the High risk group that had risk factor of brain infarction recognized from the former research tends to have higher 1st NIHss. Also the High risk group tends to have lower improved extent, but the results are not statistically significant. Furthur research on subject is needed.

  • Liu Hejian maintained that the six types of energy can become fire and focused on the treatment of fire and heat symptoms along with the prescriptions of cryotherapy, believing that a vast majority of disease are due to fire. In this study, we investigated the characteristics of Hejian's formulae by classifying medicinal ingredients in consideration of medicinal properties and efficacy in order to examine how many cold and hot medicinal ingredients are included in the formulae of Hejian. We analysis 848 formulae among 1,055 formulae in total, excluding 207 redundant ones, which includes 366 Sunmyunglon formulae, 223 Bomyeongjip formulae, 8 Samsolon formulae, 61 Sanghanjigkyeok formulae, 68 Sanghanpyobon formulae, 22 Sanghansimyo formulae, 103 Hwalbeopgiyo formulae, 186 Bodongbiyo formulae, and 18 Gagamyoungbisippalbang formulae. In the analysis of the frequency of using each medicinal herb after classifying medicinal ingredients of Hejian's formulae by medicinal properties, we found that cold medicinal ingredients accounted for 40%, the biggest share in the formulae, and hot medicinal ingredients accounted for around 45%, which indicates that Hejian's formulae consist of both elimination and reinforcement and cold and heat, rather than cold medicinal ingredients only. As a comparison of the frequency of using each medicinal ingredients for the formulae by efficacy, we found that clear heat medicinal ingredients, totify qi and replenish blood medicinal herbs, and activate blood medicinal ingredients were most frequently used.

  • Sounds and music have been used in various ways in the East and the West, as it is well known that they influence the human mind and health a lot. Recently, there have been many studies regarding the remedy through sounds and music in the West and they have made good effects in the actual therapy. In the East, people knew that sounds and music would make great effects on human mind long time ago and they placed importance on sounds and music. Although there is a Sound Therapy in Oriental Medicine, it is not studied sufficiently in modern Oriental Medicine. It does not have clear standards for the clinical application and has not been frequently used. Accordingly, Yukjagyeol which has long been used in Korean Medicine and Younggamudo which was made by Kim Il-bu in late Chosun were compared from the perspective of acoustics and demonstrative treatment theory of Korean Medicine. Younggamudo by Kim il-bu allot the five sounds such as 'Eum, Ah, Eo, Ih and Uh' to 'spleen, lung, liver, heart and kidney' respectively. As the five sounds are all vowels and vibrate the vocal band as much as possible, they vibrate and resonant the respective organs to help them to function and promote circulation. In oriental medicine, there is 'Singing and Dancing Treatment'. They say songs and dances nurtures personality, supplement blood stream and comfort the mind. As the five sounds of Younggamudo take the melody while vibrating the vocal band sufficiently, when it passes from Youngto Ga(Songs) we may dance moving our bodies according to the rhythm. Therefore Gongbeop of Younggamudo helps the functionality of human organs and promotes blood circulation. As Yukjagyeol is Sabeop(discharging method), it should be used for those who have surplus Sagi and should not use for Heojeung. As Younggamudo is Bobeop(supplementing method), it is not for Shiljeung but for Heojeung which lacks of Jeonggi. It is considered that healthy people without specific disease can use it as a preventive method of 'Chimijeong' to maintain their physical and mental health. It is considered that we can have useful effects if we apply Yukjagyeol and Younggamudo dialectically with the concept of Bosa. It is considered that concrete application to Sound Gigong can be possible by searching for the methodology for empirical further study and clinical experiments and clinical application in the future.

  • Thymosin ${\beta}4$, a small protein containing 43 amino acids, has multi-functional roles in cell physiology. It was first identified as a thymic maturation factor and recently has been shown to accelerate wound healing, hair growth, angiogenesis, tumor growth, and metastasis. It was also reported to play a key role in developing organs, including the nervous system and heart. Thymosin ${\beta}4$ induces the expression of vascular endothelial cell growth factor (VEGF), laminin-5, and other important biologically active genes. Using tissue microarray analysis, we investigated the expression patterns of thymosin ${\beta}4$ and VEGF in various normal human adult tissues. Thymosin ${\beta}4$ was highly expressed in the liver, pancreas, ductal epithelium of the salivary gland, and heart, and moderately expressed in the skin, lung, spleen, lymph node, thymus, ureter, and blood endothelial cells in both the lung and adrenal gland. The expression of VEGF generally co-localized with thymosin ${\beta}4$ and VEGF was highly expressed in the pancreas, ureter, mammary gland, liver, esophagus, and blood endothelial cells in both the lung and adrenal gland. These results suggest that thymosin ${\beta}4$ plays an important role in the function of various organs and since the expression pattern of thymosin ${\beta}4$ co-localized with VEGF, part of that function may be to induce or maintain angiogenesis.

  • This experimental study was performed to investigate the antitumor effect of Egg white combined-Chalcanthite (InSan 4, IS4) in xenografted nude mice with NCI-H460 human lung cancer cell. We cultured NCI-H460 cell lines and xenografted them on nude mice. These mice were divided into 3 groups; group with dose of 45 mg/kg IS4 orally, group with dose of 90 mg/kg IS4 orally, and the control group. They had been raised and treated for 28 days. We checked their body weight, tumor weight and volume twice a week, and their absolute organ weight, microhistological observation and biochemical blood analysis at the final day by sacrificing them. We also calculated their tumor inhibition rate (IR), mean survival time and percent increase in life span (% ILS). In this study, we observed that all of the IS4 treated mice have tumor regression, dosage-dependently, compared to the control group. Tumor weight and volume of high dose treated mice were smallest. IR increased in IS4 in a dose-dependent manner. Mean survival time and percent increase in life span (% ILS) in high-dose IS4 treatment group were the highest of the three groups. There was no significant difference in biochemical blood analysis, alanine phopsphatase (ALP), Calcium, creatinine (CRE), alanine transferase (ALT), and aspartate transaminase (AST) levels. The urea nitrogen (UN) level results significantly decreased by IS4 45 and 90 mg/kg (IS4 45 mg/kg, IS4 90 mg/kg, p<0.01). IS4 may have potential anti-tumor effect in a solid tumor induced by NCI-H460 without remarkable side effects.

  • The aim of this study was to investigate the effect of Taeeumjowuitanggagam-bang(TJV) on the mRNA expression of adipocytokines (TNF-${\alpha}$ and IL-6), and SREBPs. Mice were divided into 4 groups ; a normal group of db/+ mice, a control group of db/db mice, a group (db/db mice) treated with TJV 200 mg/kg, and a group (db/db mouse) treated with TJV 500 mg/kg. They were treated orally with TJV and measured their body weight every other day during 9 weeks. After that, we measured the mRNA expression of adipocytokines (TNF-${\alpha}$ and IL-6) and SREBPs (SREBE-1a and SREBP-1c) in liver, and blood concentration of total cholesterol, triglyceride, too. In addition, liver samples were fixed in 4% PFA for 2 hours and stored in $-70^{\circ}C$. Liver tissues were embedded in Optical cutting temperature(OCT) compound and 30 ${\mu}m$ sections were cut. Tissue sections were stained Oil-Red-O to visualize neutral lipids. Nuclei were stained with hematoxylin solution. In result, the TJV reduced the mRNA expressions of TNF-${\alpha}$ and IL-6 and SREBPs in liver and stained liver tissue less red than control group. However, there was no significant differences in total cholestreol and triglyceride blood concentration and body weight among groups. The TJV has inhibitory effect on the mRNA expression of adipocytokines and SREBPs. Therefore, it is assumed that the TJV is related to inhibiting lipogenesis in the liver
