The growth of V. parahaemolyticus was inhibited by the combination of natural products having antioxidative capacity. The growth of V. parahaemolyticus was controlled effectively by each or the combination of Paeonia japonica, Acanthodanacis cortex, Phellodendri cortex, Mori cortex radicis, Theae folium, Galla rhois, Coptidis rhizomn and Astragali radix. The growth inhibition ratio of the combination of Astragali radix, Phellodendri cortex, Coptidis rhizotna and Paeonia japonica was 95%, and its antioxidative capacity was also 5.4 times higher, and the elimination ratio of hydroxyl radical was more than 80% compared with control. As natural products might activate some parts of human body, they could be utilized as pharmaceuitcal applications, functional foods, antiaging tea, and multifunctional fermentative beverages.
Although water is an essential component of the human body and is involved in many physiological processes, the effect of a steady and sufficient water intake on blood components has not well elucidated. Therefore, we investigated the changes in hematological parameters, high-sensitivity C-reactive protein (hs-CRP), and immunoglobulin G (IgG) after water intake in 13 healthy adults. They were divided into two groups: The control group (N=4), which consumed water ad libitum, and the experimental group (N=9), which consumed 2 L of water per day. Two weeks later, blood cell counts, hematocrit, and hemoglobin content had increased in the experimental group, although not significantly (p>0.05); however, there was a significant increase in the mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) (p<0.05; and p<0.01, respectively), and a significant decrease in the mean platelet volume (MPV) (p<0.05). Of the immunologic parameters, a non-significant decrease in the concentration of hs-CRP, an indicator of cardiovascular disease risk, was observed (p>0.05). However, there was a dramatic and significant increase in the concentration of IgG (p<0.05). In conclusion, a steady and sufficient water intake may contribute to alleviate anemia by increasing hemoglobin. Additionally, it may decrease the risk of cardiovascular disease by decreasing platelet activation and concentration of hs-CRP. Furthermore, a steady intake of water may improve immune function by increasing the concentration of the components of humoral immunity.
The aim of the present study was to investigate the behavior and performance of male and female broiler chickens reared under three different colors of light (white, blue and red) in a 23L:1D of lighting program. Day-old broiler chicks were obtained and assigned to six pens (16 males and 16 females per pen). Two pens each were located in three different rooms in an environmentally controlled shed and received the different light colors. All birds received same husbandry conditions. After a 3-day adaptation to the light color, behavior observations (pecking, resting, standing and walking) were made on six focal birds per pen, representing the sex ratio, by direct visual scans for 120 minutes daily for five days a week throughout the 5-week study. Body weights and feed intake were recorded at weekly intervals. On days 19 and 33, welfare indicators (tonic immobility reaction on the 19 and 33 days old; gait scores, foot pad and hock burns scores on 33 days old) were determined. Light color had no significant effect (P>0.05) on the weight gain and feed intake of broilers, but significantly (P<0.05) influenced the feed conversion ratio. Birds receiving the blue light were more (P<0.05) efficient than those receiving white and red lights. Resting was observed to be the major behavior pattern, irrespective of sex or light color. During early growth, resting behavior tended to be lower in birds receiving red light. However, standing and walking behaviors tended to be higher in birds receiving red light in 4 to 18 day-old age and all of experimental periods, respectively. These data indicate that light color can influence broiler performance and behavior.
From the mid-1980s '91s, remarkable Ethnicism and Primitivism in the Europe fashion trend could be represented as an exotic taste longing for secenery and emotion of non-europe area in the West. These phenomenon could be found out in connection with Acculturation, which means when two different cultures or more were contacted they were identified or merged in process of diffusion and change of them. This point of view was the culture anthropologic one that make a comparison and analysis of sameness and difference between cultures. The purpose of this study was to illuminate exotic taste represented in costume in the cluture-anthroplogic aspect, to compare with beauty of costume that each culture of costume and the meaning of the times due to those differences. an aspect of the exotic taste and character in the western costume that was inspected by dividing into 'Primitivism', 'Oriental element' and 'the element of a national costume in the East European bloc ' were as follows; First, Primitivism had something in common with what was pursued in the trend of Modern Art, through the late 19th century to the early 20th century. In fashion fettered by technique, the creation expressed in a free was and showed simple beauty of costume. At the same time, pure emotion expression, creative power and witty strong expression give the cognition of transcendency breaking the routine and the cognition of complexity of an included conception. Those are garments showing not only the primitive thought and mysticism but a fancy, an abstraction, and a life. Colors and accessaries which described nature and matched simple costume composition to the expression of various material or patterns transmitted the image of the primitive strongly. Second, "Drental element" which had an effect on western custome historically in a long time had outstanding luxurios adornmental beauty of custome. Extending from the Arab stated India, China, Korea, Japan, each national costume with a gay national culture became one of motif. Various ornamental factors expressed on Trapez Line, Sime Line and Drape, or Raied style, which did not restrict the body. Those were not only functional Easy Look, but were also satisfying human's ornamental desire. Third, national factors in the East European bloc are theme that begins to be embossed in the late 80's. In view of a political change and cultural situation with a double character of Europe and Orient, it was estimated that national factors have great importance in fashion. Item concerned with new concern appeared at Autumn & Winter collection. It shows elegant and graceful beauty of costume by adding a fur or jewel to simple form. These national factors in the East European bloc are simple form, but shows the difference in more cubic formation than form expressed in Primitivism or Oriental factors Exotic taste appeared form 80's to 91's, is thought to create an forgotten romantic emotion and traditional fashion
Background & Purpose : Acupuncture with aromatherapy (AA) is a branch of complementary or alternative therapy recently growing in use. As the use of aromatherapy itself has grown so rapidly in recent years, studies about its safety have been accumulating. However, safety of AA has not been studied clinically and the treatment method which has the needles inserted after spreading essential oils exposes the human body more directly to components than aromatherapy. Therefore, we examined the safety of AA on patients treated thereby and physicians practising it. Methods : We observed all inpatients treated with AA from November 21, 2005 to March 31, 2006, in Kyung Hee Oriental Medical Center. During treatment, we monitored all of the newly developed signs from the patients to assess the adverse effects of AA. The patients' and physicians' general characteristics (gender, age, present illness, and treatment days) were obtained from medical records and analyzed to assess the clinical safety of AA in detail. Results : There were 440 patients treated with AA; clinical adverse effects appeared in 3 of them, which can be assessed as 0.7%. The major symptom was chest discomfort and choking originated from smell aversion condition (2 patients), and the other adverse effect was sensation of itching and reddening. However, none of them seemed to have direct relation with AA. A total of eight physicians applied AA and there were no symptoms related to it among them. Conclusions : We suggest that our results will contribute to confirming the safety of AA by offering clinical evidence.
In order to develop the aerosol bolus technique which is thought to be a potential tool for probing geometries or abnormalities of small airways, an experimental system of measuring fast time variations of particle concentration in the inhaled and exhaled breathing air was developed. The system generates monodisperse sebacic acrid particles of 1 micron size and 1.2 of geometric standard deviation in high concentration of $10^8$ particles/cc, delivers a short pulse of particles at the controlled instant during inhalation using a solenoid valve, and measures the fast change of particle concentration in using the laser light scattering. Successful operation of the generator and the measuring system was confirmed by smooth concentration profiles in inhalation. It was also confirmed that maintaining a constant breathing rate is essential to stable outputs and any disturbance in flow rate near the mode (maximum concentration) induces a large number of spurious peaks in the exhalation. Experimental data without strict control of breathing flow rate showed a substantial amount of scatter. The measured results showed an improvement in scatter over the existing results. When compared with theoretical predictions from 1-D convective diffusion equation and other experiments, general characteristics of dispersion for several penetration depths showed a good agreement, but there exists some difference in absolute values, which is attributed to the difference in body conditions. Improvements are needed in the theory, especially in relation to correcting for the effect of breathing flow rate.
In order to study tile effects of moxibustion on renal failure induced by $HgCl_2$ in rats aminal experiments were carry out. The moxibustion was treat into Sin-soo locus(VII23), We-soo locus(VII21) and Sin-soo + We-soo loci these loci were correspond to human body. Experimental group were divided into 4 groups : lontrol group, moxibustion groups treat on Sin-Soo and We-Soo, Sin-Soo + We-Soo group. The obtained results were as follows : 1. The concentration of serum sodium were inreased in all the groups, compared with those of the control group. Sin-Soo, We-Soo, Sin-Soo + We-Soo loci showed increased on the 1st and 3rd days. All three experimental groups showed a significant increased on 3rd day. 2. The concentration of serum potassium were decreased in all the group, compared with those of the control group. Sin-Soo, We-Soo showed a significant decrease on 3rd day. Sin-Soo + We-Soo showed a little decrease but do not significant decrease. 3. The levels of serum total protein were increased in all the group, compare with those of the control group. Sin-Soo, We-Soo show a significant increased or 3rd day. Sin-Soo + We-Soo do not showed a significant increased. 4. The levels of serum albumin were decreased in all the groups, compared with those of the control group. Sin-Soo, Sin-Soo + We-Soo showed a significant decrease on 3rd day. We-Soo does not showed a significant decrease. 5. The concentration of serum blood urea nitrogen were decreased in all the groups, compared with those of the control group. Sin-Soo, We-Soo, Sin-Soo + We-Soo showed a significant decrease on 3rd day. 6. The levels of serum alkaline phosphatase were decreased in all the group, compared with those of the control groups. Sin-Soo, We-Soo showed a significant decrease on 3rd day Sin-Soo + We-Soo not a significant decrease. In conclusion, the result of this study seemed to effect on the treatment for renal failure induced by $HgCl_2$.

Acrylic resin is widely used in dental practice. However, the residual monomer in acrylic resin could act as a negative biocompatability on human body. The aim of this study was to evaluate the amount of the monomer elution from polymerized orthodontic acrylic resin. Orthodontic acrylic resin was used in the study. The curing condition of the resin was controlled by temperature, pressure, aquatic and atmospheric environment. The duration and amount of monomer elution and timedependent plot was recorded by high performance liquid chromatography. The result showed that the only monomer eluted from the resin was methyl methacrylic acid. And the amount of the monomer elution has diminished considerably by time progress especially within 24 hours. Furthermore, elution of the residual monomer was significantly lower in group of pressure, moisture and elevated temperature than control (p<.05). According to this study, it was thought that the elution of residual monomer might be influenced by curing environment.

Millettia erythrocalyx, a species of plant in the Fabaceae family, is widely distributed in the tropical and subtropical regions of the world, such as the Indies, China, and Thailand. The antiviral activity of flavonoids from M. erythrocalyx has been reported; however, the antioxidative and anticancer activities of M. erythrocalyx remain unclear. In this study, we evaluated the antioxidative and anticancer effects of ethanol extract of M. erythrocalyx (EEME) and the molecular mechanism of its anticancer activity in human hepatocellular carcinoma HepG2 cells. EEME exhibited significant antioxidative effects, with a concentration at 50% inhibition ($IC_{50}$) value of $2.74{\mu}g/ml$, as measured by 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay; moreover, it inhibited cell proliferation in a dose-dependent manner in HepG2 cells. Cell cycle analyses showed that EEME induced HepG2 cell accumulation in the subG1 phase in a dose-dependent manner. EEME also induced apoptosis of HepG2 cells, with increases in apoptotic cells and apoptotic bodies, as detected by Annexin V and 4,6-diamidino-2-phenylindole (DAPI) staining, respectively. Treatment with EEME resulted in increased expression of First apoptosis signal (Fas), a death receptor, and Bcl-2-associated X protein (Bax), a proapoptotic protein, and the activation of caspase-3, 8, and 9, resulting in the cleavage of poly (Adenosine diphosphate-ribose) polymerase (PARP). Collectively, these results suggest that EEME may exert an anticancer effect in HepG2 cells by inducing apoptosis via both the intrinsic and extrinsic pathways.

Most degeneating diseases and back pains in the orthopaedic disease are originated from the unbalance of stress distribution in the low-lumbar spine. Therefore the stress analysis of lowerback is indispensible to the clinical diagnosis for the developing reason and the developing process of diseases. Therefore the same model materials as following are eveloped to analyze the stress distributions of lower-back by photoelastic experiment. The verterbral body and the process are molded from epoxy resin(the weight ratio of Araldite and hardner is 10 to 3), models are geometrically identical to them in vivo respectively and the ratio of their elastic modulus to that of model material is 1 to 10. It is assured that KE-1300 Silicon(E=0.8MPa), TSE-3562 Silicon(0.5MPa) and the composite silicon(3MPa) (the weight ratio of KE-1300 silicon and Jioreal : 10 to 4) are respectively effective as the model materials of ligament, musles and intervertevral disc which is essential to the movement of low-lumbar spine. All the elements associated with the movement of the low-lumbar spine are molded through the molding method developed in this research and assembled with the angles between the verterbra and the disc in the normal human lumbosacral spine. The stress distributions of the assembled model are analyzed by photoelastic experiment. It is certified by comparing the results of photoelastic experimebt with the clinical situations that the loading dveice and the loading conceptions used in this paper are effective.
