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.

The effects of duration and time-dependent, high-intensity exercise on hematological properties and inflammation-related parameters in rats were studied. 20, 60, and 120 min of high-intensive exercise were performed daily for 8 weeks. None of the complete blood count (CBC) factors were affected by the exercise, except for the leukocyte concentration which, in the 20 min group, showed an increase of 47% compared to the control, but this was decreased after 60 min by 30% compared to the control. As exercise was performed for 60 min or longer, serum concentrations of $Fe^{++}$, unsaturated iron biding capacity (UIBC), and total iron biding capacity (TIBC) were significantly elevated in comparison to the control, where 20 min of exercise did not show any change. Both levels of interleukin-6 (IL-6), a pro-inflammatory cytokine, and interleukin-10 (IL-10), an anti-inflammatory cytokine in the serum, were elevated in response to the high-intensity exercise, however the rate of IL-6 increase was higher than the rate of exercise intensity increase, thus the offset of inflammation might be suggested. The concentration of nitric oxide (NO) in the serum became high in response to the exercise. Overall, the current observation suggests that inflammation-like responses to high-intensity exercise might be due to high circulation of blood flow and high oxygen requirement, resulting in systemic damages. However, under the current high-intensity exercise conditions, more than 20 min of exercise might not be suggested for health care purposes.

We analyzed 57 types of herbal medicines for Soeumin, clinically applied in Dongyisoosebowon. In order co discover the standard of herbal classification for the Sasang Constitutions, four concepts of Sasang Medicine were applied. These included 'Sadangron (theory of four groups)', 'Seungganggaehap(ascending-descending and gathering-dispersing)', 'Pyorihanyoul(exterior-interior and hot-cold)', and 'Hyungchiaekmi(fragrance, smell, bodily fluid and taste)'. According to these analyzing methods of herbal properties, we have reached the following conclusions: 1. Lee Je-ma first established the physiology of the internal organs of the Sasang Constitutions through the understanding of constitutional pathology. Dr. Lee then classified herbal medicines into four constitutional groups by observing the herbal effects according to such perspective of organ physiology and pathology. 2. Among the Sasang concepts applied in the analysis of herbal properties based on the physiology and pathology of Sasang constitutions, 'Seungganggaehap (ascending-descending and gathering-dispersing)' was found to be the most useful. Meanwhile, 'Sadangron, (the theory of four groups - Spirit, Qi, Blood and Essence),' along with 'Pyorihanyoul (exterior-interior and hot-cold)' and 'Hyungchiaekmi (fragrance, smell, bodily fluid and taste)' were partially useful. 3. Herbal medicines for Soeumin are characterized by ascending energetics that protect the Yang Qi. The 'Exterior heat disease' is treated with herbal medicines that raise the "Exterior Yang" in three different way: by tonifying Qi. by tonifying Blood and by releasing exterior. The 'Interior cold disease' is treated with herbal medicines that descend "Interior Yin" in two ways. One by warming the stomach, and the other by regulating Qi. 4. Cases where a whole category of herbs with the same effect have been applied co one constitution, are most frequent among Shaoyin herbs. There was an intimate connection between the treatment methods and the traditional effects of herbs for 'Soewnin'. These discoveries allowed us to see that the development of the pharmacology of the Sasang Constitutional pathology more progressed in 'Soeumin'. *analysing simple herbs of "DongEuiBoGam JangBu" we compare JangBu of traditional oriental medicine with JangBu of Sasang Constitutional Medicine. So we can comprehend the JangBu's difference of traditional-oriental with sasang-constitional medicine.

OMH which is known for its properties of recruiting vitality, is composed of Polygonum multiflorum Thunb. and Sesamum indicum DC.. This formula is known to possess the properties of recruiting vitality, blackening white hair and expanding life span. 16-week-old SD-Rats were treated with OMH for 16 days. After 24 hours, the rats were treated with MTX(Mthotrexate is oral administrated for 4 days(1mg/kg/day), in order to lower immunity. Then, These rats were classified in to groups, the N-16 group(not specially tested), the Control group(MTX), the OMH-L group(2.5% OMH+MTX)&the OMH-H group(10% OMH+MTX) and 6 rats were assigned to each group. After 18 hours from MTX treatment the organ index of the rats from each group Thymus and Spleen were measured. The percentage of CD+4, CD8+ T cell were measured and compared by flow cytometer. 1) Rats from the OHM-L&OMH-H group showed higher organ indexes of the Thymus and Spleen compared to the rats from the Control Group. This proves that OMH possesses the properties to mitigate degenerations of immunity($F_{thymus}=20.162,\;F_{spleen}=5.882$, ANDVA, p<0.05). 2) The rats from the two OMH groups showed higher rates of CD4+ T cell counts compared to the control group(F=26.906, ANOVA, p<0.05). CD8+ T cell showed lower rates compared to the Control group, but showed no differences within the two OMH groups(F=1.254, ANOYA, p>0.05). CD4+/CD8+ showed higher rates in the two OMH groups compared to the control group which can be thought as a proof that OMH prevents depression of immune response(F=10.554, ANOVA, p<0.05). In this test 16 week-old rats were used, which can be considered as the middle and prime age of the human being. These rats were treated with OMH which ended up showing properties of mitigating degeneration of immune responses and maintaining T-cell rates within the blood. It was possible to study that OMH possesses the properties to increase immune responses.

We present a continuous cell separator that achieves density-dependent and size-independent cell separation based on the net force of gravity and buoyancy forces on the cells in dissimilar density fluids. Previous cell separators are, based on the size or dielectrophoretic property of the cells and, are suitable for size-dependent and density-independent cell separation. However, these properties can make it difficult to collect the same types of cells with the same density but with size variations. The present separator, however, is capable of collecting the same types of cells based on the cell density in the fluid. Regardless of cell size, the proposed chip isolates low density cells, (white blood cells, or WBCs) at the upper outlet while obtaining high-density cells (red blood cells, or RBCs) from the lower outlet based on density. Efficiency levels for separation of WBCs and RBCs were $90.9{\pm}9.1%$ and $86.4{\pm}1.99%$, respectively. The present separator therefore has the potential for use in the pretreatment of whole blood.

The aim of this study was to investigate the effect of supplemental recombinant bovine somatotropin (rbST) and cooling with misters and fans on renal function in relation to regulation of body fluids in different stages of lactation in crossbred Holstein cattle. Ten, 87.5% crossbred Holstein cattle were divided into two groups of 5 animals each, housing in a normal shaded barn (NS) and in a shaded barn with a mister-fans cooling system (MF). The experiment in each group was divided into 3 phases, early- (Day 75 postpartum), mid- (Day 135 postpartum), and late stage of lactation (Day 195 postpartum). The pre-treatment study was conducted on the starting day of each stage of lactation and the treatment study was performed after the end of the pre-treatment, during which the animal was injected with 500 mg of rbST (POSILAC) every 14 days for three times. During the study, ambient temperature at the hottest period daily in the MF barn was significantly lower, while relative humidity was higher than that of the NS barn. The temperature humidity index (THI) in both barns ranged from 79-85 throughout the periods of study. Cows in the MF barn showed a lower rectal temperature and respiration rate as compared with cows in the NS barn. The effect of rbST administration increased both rectal temperature and respiration rates of cows housed in either the NS or MF barn. Milk yield significantly increased in cows treated with rbST in all stages of lactation. Increases in mammary blood flow, accompanied by increases of total body water (TBW), extracellular fluid (ECF), blood volume (BV) and plasma volume (PV), were observed in both groups of cows receiving rbST in all stages of lactation. No alterations of renal blood flow and glomerular filtration rate were observed in cows receiving rbST, but decreases in urinary excretion and fractional excretion of sodium, potassium and chloride ions appeared to correlate with reduction in the rate of urine flow and osmolar clearance during rbST administration. These results suggest that the effect of rbST supplementation to cows housed either in NS or MF barns on body fluid volume expansion is attributable to changes in the rate of electrolyte excretion by the kidney. The increased availability of renal tubular reabsorption of sodium, potassium and chloride ions during rbST treatment was a major factor in retaining body water through its colligative properties in exerting formation of an osmotic force mechanism.

The selective targeting of an integrin ${\alpha}_v{\beta}_3$ receptor using radioligands may enable the assessment of angiogenesis and integrin ${\alpha}_v{\beta}_3$ receptor status in tumors. The aim of this research was to label a peptidomimetic integrin ${\alpha}_v{\beta}_3$ antagonist (PIA) with $^{99m}Tc(CO)_3$ and to test its receptor targeting properties in nude mice bearing receptor-positive tumors. PIA was reacted with tris-succinimidyl aminotriacetate (TSAT) (20 mM) as a PIA per TSAT. The product, PIA-aminodiacetic acid (ADA), was radiolabeled with $[^{99m}Tc(CO)_3(H_2O)_3]^{+1}$, and purified sequentially on a Sep-Pak C-18 cartridge followed by a Sep-Pak QMA anion exchange cartridge. Using gradient C-18 reverse-phase HPLC, the radiochemical purity of $^{99m}Tc(CO)_3$-ADA-PIA (retention time, 10.5 min) was confirmed to be > 95%. Biodistribution analysis was performed in nude mice (n = 5 per time point) bearing receptor-positive M21 human melanoma xenografts. The mice were administered $^{99m}Tc(CO)_3$-ADA-PIA intravenously. The animals were euthanized at 0.33, 1, and 2 hr after injection for the biodistribution study. A separate group of mice were also co-injected with 200 ${\mu}g$ of PIA and euthanized at 1 hr to quantify tumor uptake. $^{99m}Tc(CO)_3$-ADA-PIA was stable in phosphate buffer for 21 hr, but at 3 and 6 hr, 7.9 and 11.5% of the radioactivity was lost as histidine, respectively. In tumor bearing mice, $^{99m}Tc(CO)_3$-ADA-PIA accumulated rapidly in a receptor-positive tumor with a peak uptake at 20 min, and rapid clearance from blood occurring primarily through the hepatobiliary system. At 20 min, the tumor-to-blood ratio was 1.8. At 1 hr, the tumor uptake was 0.47% injected dose (ID)/g, but decreased to 0.12% ID/g when co-injected with an excess amount of PIA, indicating that accumulation was receptor mediated. These results demonstrate successful $^{99m}TC$ labeling of a peptidomimetic integrin antagonist that accumulated in a tumor via receptor-specific binding. However, tumor uptake was very low because of low blood concentrations that likely resulted from rapid uptake of the agent into the hepatobiliary system. This study suggests that for $^{99m}Tc(CO)_3$-ADA-PIA to be useful as a tumor detection agent, it will be necessary to improve receptor binding affinity and increase the hydrophilicity of the product to minimize rapid hepatobiliary uptake.

This study was performed to verify the effects of corn husk powder on serum lipid levels of high-fat diet-induced mice from a nutritional viewpoint. Powder of corn husks has been used as a folk remedy from ancient times in Korea. In the case of corn husk measurement of TPC (p<0.05), ABTS+ radical scavenging activity of trolox (p<0.05), DPPH radical scavenging activity (p<0.05), and measured value of FRAP (p<0.0001) were higher in ethanol extract than water extract. Weight of livers was significantly higher in the control group and high-fat diet group compared to groups fed 10% and 20% corn husk powders with high-fat diet (p<0.0001). For blood HDL-cholesterol concentration, mice fed 10% corn husk powder with high-fat diet ($160.00{\pm}16.17mg/dL$) showed significantly higher levels compared with the other three groups (p<0.05). Mice fed 10% and 20% corn husk powders with high-fat diet showed high numerical values of $13.50{\pm}2.51$ and $11.25{\pm}2.87mg/dL$, respectively. For triglyceride concentration in blood, mice fed 10% ($83.50{\pm}19.30mg/dL$) and 20% ($88.50{\pm}22.25$) corn husk powder with high-fat diet showed very low levels compared to the control group and high-fat diet group. In the case of leptin, the high-fat diet group showed a significantly high level of $5.88{\pm}3.53ng/dL$. Groups fed 10% and 20% corn husks with high-fat diet showed low numerical values of $2.72{\pm}2.34ng/dL$ and $1.10{\pm}0.62ng/dL$, respectively (p<0.05). Corn husk powder increased high HDL-cholesterol concentration in blood while lowering triglyceride concentration and leptin secretion. Therefore, powder of corn husks has utility in the food industry and food processing.

It was investigated that how the periodic exposure to heat environment, and the treatment of korean white and red ginseng extracts had effects on the weight, diet uptake, blood components, organ weight, and the lipid peroxidation of liver in male S.D. rats. In the result of experiments using rats, chronic heat environment for 7 days at $38^{\circ}C$, 5 hrs per day, induced significant decrease of an average increase rate of body weight, but diet uptake was not affected clearly. In heat environment, the number of red blood cells and hemoglobin were not changed, but the number of white blood cells was significantly increased. The liver weight against body weight was decreased in rats. Also, MDA contents, related to lipid peroxidation, were remarkably increased in rat liver by heat environment. These physiological changes were attenuated by treatments of white and red ginseng extracts before and after exposure to heat environment, particularly in growth rate and lipid peroxidation of liver in rats. Also, red ginseng extracts had a better effect, though it was not that significant, than the white ginseng on the inhibition of lipid peroxidation and the weight change of liver. Although the investigation on the effective components and the study on the activity changes of associated materials are needed to perform, these present results imply that Korean ginseng may contribute to protection of body homeostasis against drastic climate changes.

This study was performed to investigate the ameliorating effect of a hangover beverage mixture (SBJ) that contains Dendropanax morbifera Lev. and several medicinal plant extracts, on hepatoprotection and alcohol-metabolizing enzymes in alcohol-induced hangover in both in vitro and in vivo models. In human hepatoma cell line, HepG2, 300 mM of ethanol-induced hepatotoxicity was significantly improved by pretreatment of SBJ by dose-dependent manner. In the in vivo study, administration of alcohol to rats raised to the concentration of blood alcohol and lactate dehydrogenase (LDH). Blood alcohol and LDH levels in SBJ-treated rats significantly decreased at 0.5 h and 8 h after acute ethanol administration (40%, 4.6 g/kg body weight) as compared to alcohol-treated rats. Hepatic alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) activity were significantly higher in SBJ-treated rats than in alcohol-treated rats. SBJ supplementation reduced formation of malondialdehyde (MDA), and inhibited reductions of hepatic superoxide dismutase (SOD), hepatic glutathione (GSH), glutathione-S-transferase (GST), glutathione reductase (GR) and glutathione peroxidase (GPx) levels, compared with rats administered alcohol. Plasma catalase (CAT), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels showed unaltered resulted in all experimental groups compared with the control group. These results suggest that SBJ exhibit hepatoprotective properties by enhancing ADH, ALDH activity and stimulating the antioxidant defense system in alcohol-induced hangover.
