For better diagnosis and prescription in Korean traditional medicine, Lee Je-Ma (1837-1900) created Sasang Constitution classification which was divided into four groups of Taeyangin, Soyangin, Taeumin and Soumin based on both body shape and natural disposition. The purpose of this study was to investigate the characteristics of facial skin parameters (hydration, lipid and pH) on forehead and cheek according to Sasang Constitution classifications of Taeumin, Soyangin and Soumin in Korean. Eighty-nine Korean female subjects were recruited for this study and the average age of them was 19.9${\pm}$0.84 years. The four groups by the Sasang Constitution were classified by questionnaire for the Sasang Constitution classification proposed by Kyung-Hee Oriental Medicine Hospital. Consequently, thirty-eight (42.7%) among the subjects were grouped into Soumin, twenty-nine (32.6%) into Taeumin, twenty (22.5%) into Soyangin and two (2%) into Taeyangin. Taeyangin group was excluded from statistical analysis due to small subjects. Hydration, lipid and pH parameters on forehead and cheek were measured by using non-invasive instruments of Corneometer (CM 825, Schwarzhaup, Germany), Sebumeter (SM 815, Schwarzhaup, Germany) and Skin-pH-meter (pH 905, Schwarzhaup, Germany), respectively. The measurements by the same investigator were performed under standardized condition with a room temperature of $21^{\circ}C$ and a humidity level of 40% to 50%. As a result, hydration (F=25.481, p=.000), lipid (F=5.753, p=.005) and pH (F=5.010, p=.009) of the forehead skin showed significant differences in the order of Taeumin, Soyangin and Soumin. Hydration (F=23.216, p=.000), lipid (F=6.898 p=.002) and pH (F=5.070, p=.008) of the cheek skin showed significant differences in the order of Taeumin, Soyangin and Soumin. In conclusion, facial skin surface seemed to be dependent on Sasang Constitution classification in Korean. These findings indicated that Sasang Constitution classification might be an useful esthetic treatment for caring facial skin in the future.

Precipitation samples were collected by the wet-only sampling method at Seoul from September 1993 to June 1995. Sample were analysed for the anions $(NO_3^-, NO_2^-, SO_4^{2-}, Cl^-, and F^-)$ and cations $(Na^+, K^+, Ca^{2+}, Mg^{2+}, and NH_4^+)$ in addition to pH and electric conductivity. In order to establish the chemical analysis data of high quality, the assurance checks for analytical data of precipitation were performed by considering the ion balance and by comparing the measured conductivity with the calculated conductivity. As we applied the various assurance checking methods by the ion balance used until recently to a data set measured in this study, the f value expressed as $\Sigma C/\Sigma A$ was found to be not appropriate for the data screening. Also, the scattering plot between cations and anions in each sample was found to show the general tendency of ion balance but was proved to not quantitate the standard of data screening at a data set of samples of various concentration levels. The h value defined as (A-C)/C for C $\geq$ A and (A-C)/A for C < A was used to check the ion balance. However, the standard of data screening by h value must very in response to total ion concentration of samples. In this study, the quality assurance of chemical analysis data was checked by considering both the ion balance of evaluating by h value and the conductivity balance. Further the quality control was achieved by these quality assurance methods. As the result, 67 samples among total 77 were obtained as valid. As the central tendency value for a statistical summary in the analytical parametr of samples, the volume-weighted mean value was found to represent more the general chemistry of precipitation rather than the arithmetic mean. The volume-weighted mean pH was 5.0 and 25% of samples was less than this mean. The concentrations of sufate and nitrate in precipitation were 90.4 ueq/L and 32.4 ueq/L which made up 59% and 21% of all anions. The raion of $SO_4^{2-}/(NO_3^- + NO_2^-)$ in precipitation was 2.7, which indicates that the contributions of $H_2SO_4$ and $HNO_3$ to the acidity of precipitation are 70% and 30%, respectively.
Radiotherapy would be the choice of treatment for human cancers, because of high cost-effectiveness. However, a certain population of patients shows a resistance to radiotherapy and recurrence. In an effort to increase the efficacy of radiotherapy, many efforts were driven to find the genes causing the unresponsiveness to ionizing radiation. In this paper, we compared the gene expression profiles of two lung cancer cell lines, H460 and H1299, which showed differential responses to ionizing radiations. Each cell were irradiated at 2 Gy, and harvested after 0, 2, 4, 8, 12 and 24 hours to examine the expressions. Two-way ANOVA analysis on time-series experiments of two cells could select 2863 genes differentially expressed upon ionizing radiation among 32,321 genes in microarray (p<0.05). We classified these genes into 21 clusters by SOM clustering according to the interaction between cell types and time. Two SOM clusters were enriched with apoptosis-related genes in pathway analysis. One cluster contained higher levels of phosphatidyl inositol 3-phosphate kinase (PI3K) subunits in H1299, radio-resistant cells than H460, radiosensitive cells. TRAIL receptors were expressed in H460 cells while the decoy receptor for TRAIL was expressed in H1299 cells. From these results, we could characterize the differential responsiveness to ionizing radiation according to their differential expressions of apoptosis-related genes, which might be the candidates to increase the power of radiotherapy.
This research focused on the solid and nitrate removal efficiency in a solid digestion-denitrification column. The 20 L up-flow column consisted of 18 L acrylic column with 2 L down-comer inlet tube located in the middle. In the first part, the wastewater with high suspended solids from the Tilapia fish tank was applied into the sedimentation unit at 5 variable flow rates i.e., 11.25, 25.71, 60, 105.88 and 360 L/h. The results indicated that the flow rate of 11.25 L/h (0.57 m/h) gave the highest solid removal efficiency of $72.72%{\pm}8.24%$. However, the total suspended solids removal was highest at 360 L/h (18.13 m/h). In the second part, methanol was added as an external organic carbon source for denitrification process in a hybrid column containing settled solids. The COD:N ratios of 0.5:1, 1:1, 2:1, 3:1, 4:1, 5:1 and 6:1 were investigated and compared with control without methanol addition. This experiment was operated at the HRT of 1 h with 450 L wastewater from recirculating aquaculture pond containing 100 mg-N/L sodium nitrate. The results indicated that the COD:N ratio of 3:1 gave the highest nitrate removal efficiency of $33.32%{\pm}21.18%$ with the denitrification rate of 5,102.88 mg-N/day.
Objective : This study was intended to ascertain the protective effect of phenolic-rich fraction (PRF) from Fructus Schisandrae on SH-SY5Y cells. Methods : PRF was obtained from the 80% ethanol extract of Fructus Schisandrae by Sepabeads SP-850 column chromatography. The neuroprotective effect of the FS PRS was investigated due to the hydrogen peroxide $(H_2O_2)-induced$ apoptosis of cultured SH-SY5Y cells. Results : Cell viability assays revealed that pretreating SH-SY5Y cells with PRF (10-200 ${\mu}g/mL$) resulted in significant dose-dependent protection against $H_2O_2-induced$ cell death. The effect was assessed by flow cytometric analysis of DNA contents using propidium iodide (PI) staining. The population of apoptotic cells was increased by 32.89% in only $H_2O_2$ (150 ${\mu}M$)-treated environment, but it was reduced by pre-treatment of FS PRF (200 ${\mu}g/mL$) to 21.61%. $H_2O_2-induced$ caspase-3 activation and PARP cleavage were reduced in FS PRF pre-treated cells, and PRF led to an apparent suppressive effect on the oxidative stress induced by reactive oxygen species (ROS). Conculsion : This study showed that Fructus Schisandrae should be useful for the treatment prevention of neurodegenerative diseases associated with elevated ROS levels.
The purpose of this study was to evaluate the efficacy and cross-protection of serovar 12 against serovar 4 or 5 of H parasuis with M+$Parapac^{(R)}$. A total of 141 piglets from 2(A and B) farms were used and divided into experimental group and control group in each farm. Farm A has been detected H parasuis serovar 12, whereas farm B has been detected H parasuis serovar 4 or 5 from post-weaned pigs with PMWS. The piglets were vaccinated intramuscularly with 2.0ml of M+$Parapac^{(R)}$ in experimental group or normal saline in control group at 1 week of age. A same booster dose was given at 3 weeks of age. In order to value the antibody titer to H parasuis using by tube agglutination test, blood samples were collected from piglets at the aged of 1 week, 6 and 14 weeks. In experimental group and control group, the average antibody titers were $32.5{\pm}21.0,\;114.5{\pm}34.0,\;98.1{\pm}55.4$ and $32.9{\pm}18.6,\;25.8{\pm}36.9,\; 746.7{\pm}1,215.8$ at the aged of 1 week, 6 and 14 weeks, respectively. The cumulative clinical sign indexes by standard guideline of Schering-Plough Animal Health Corp were 486 and 1,069, respectively. The average daily gains and feed conversion rates were $0.553{\pm}0.016kg$ and $0.492{\pm}0.004kg$, and 1.99 and 2.24, respectively. The average gross lesion scores were $1.0{\pm}0.8$ and $1.9{\pm}0.6$, respectively. According to these results, the M+$Parapac^{(R)}$ containing H parasuis serovar 12 may be induce circulating antibodies that cross-react with serovar 4 or 5 and have a protection of PMWS with H parasuis.

This study was performed to establish the fermentation method of non-steamed brown rice vinegar using starch saccharifing enzyme. During vinegar fermentation, initial pH had increased in the higher concentration of alcohol and acetic acid. Final pH was gradually changed to pH 2.90~3.44 from 3.44~4.06. The higher total acidity of brown rice vinegar resulted from the higher alcohol concentration. The total acidity was slightly dropped after gradually increasing from the starting of fermentation. Initial pH was decreased from 3.67 to 3.16. The total acidity was gradually increased from the first day of fermentation with 1.02, it was 1.54 on the second day after fermentation and there was a tendency to decreased after the highest values with 6.53 fermentation for 12 days. In organic acid composition, oxalic, malic, acetic, citric, and succinic acid were detected. The total free amino acid was decreased to 1,121 mg%. The major amino acids were ${\gamma}$ -aminobutyric acid, $\alpha$-aminoadipic acid and alanine, and ${\gamma}$-aminobutyric acid was the highest (539 mg%). The mineral contents such as P and K was high in sample and followed by Mg, Na, Ca.
An investigation was carried out to study the effect of two housing systems on physiological responses and energy expenditure of sheep in a semi-arid region of India. Two types of housing management were adopted. First was a shed- $6{\times}3\;m^2$ structure with all the four sides of 1.8 m chain link fencing with a central height of 3 m. The roof was covered with asbestos sheets and with mud floorings. Second was an open corral- $6{\times}3\;m^2$ open space with all the four sides covered with 1.8 m chain link fencing. Thirty-four (32 ewes and 2 rams) sheep of native Malpura breed aged about 18 months (body weight 28 kg ewes; 35 kg rams) were grazed together on a 35 ha plot of native range. All the sheep were grazed as a flock from 08.00 to 17.00 h during a yearlong study. The flock was divided into two groups (16 ewes+1 ram) in the evening and housed as per the systems (Shed and Open Corral). Dry and wet temperatures were recorded at 06.00 h and 21.00 h using a wet and dry bulb-thermometer both inside the shed and in the open corral and temperature humidity index (THI) was calculated. There was significant (p<0.05) difference in the THI between shed and open corral in all the seasons, indicating that shed was always warmer compared to open corral. Rectal temperature (RT) of both the groups of sheep was similar during morning as well as evening throughout the seasons. There were significant (p<0.05) differences in the skin temperature (ST) and respiration rate (RR) between the two groups at both the measurements in all the seasons. Highest energy expenditure (EE) was recorded inside the shed at 21.00 h (224 kJ/h) during monsoon and lowest at 6.00 h during winter (119 kJ/h). There was a significant (p<0.05) difference between the EE inside the shed and that in the open corral. It was concluded that housing had significant effects on the physiological responses and EE of sheep. Provision of housing at night was stressful during monsoon (with less rainfall) and summer, whereas it was protecting the sheep from acute cold during winter in a semi-arid region of India.
Objectives : The present study investigated inflammatory effect of Rheum undulatum L. in lipopolysaccharide-exposed rats and Raw 264.7 cells. Methods : Male rats weighting $185.39{\pm}8.21g$ fed basal diet for 1 week and 32 rats were divided into a control group and 3 experimental groups. We fed a control group of rats a basal diet and administered normal saline(100 mg/kg, 1time/1day) for 6 weeks. And we fed basal diet and administered an extract of Rheum undulatum L.(100 mg/kg, 200 mg/kg, 300 mg/kg, 1time/1day) to each experimental group of rats. We measured the plasma concentration of $IL-1{\beta}$($interleukin-1{\beta}$), IL-6 and $TNF-{\alpha}$(tumor necrosis $factor-{\alpha}$), liver cytokines, Raw 264.7 macrophages cytokines. Results : The plasma concentration of $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ peaked at 5h(hour) after LPS(lipopolysaccharides) injection, and the values of the Rheum undulatum L. extract groups were lower than those of the control group. In the increment of these cytokines concentration at 2h and 5h after LPS injection, the Rheum undulatum L. groups were lower than that of control group. The plasma concentration of IL-10 peaked at 5h after LPS injection, and the values of the Rheum undulatum L. extract groups were higher than those of the control group. In the increment of this cytokine concentration at 2h and 5h after LPS injection, the Rheum undulatum L. groups were higher than that of control group. Liver cytokines measurement was done at 5h after LPS injection. The concentration of liver $IL-1{\beta}$ and IL-6 in the Rheum undulatum L. groups was lower than that of the control group. The concentrations of liver $TNF-{\alpha}$, and IL-10 showed no significant differences among all the treatment groups. In the studies of lipopolysaccharide-exposed Raw 264.7 cells, the concentration of $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ in the lipopolysaccharide-exposed cells groups was higher than that of control group(normal group), and in the lipopolysaccharide-exposed cells groups, these values showed a tendency to decrease in the Rheum undulatum L. groups. The concentration of IL-10 in the lipopolysaccharide-exposed cells groups was higher than that of control group(normal group), and in the lipopolysaccharide-exposed cells groups, the values showed a tendency to increase in the Rheum undulatum L. groups. Conclusions : These results indicate that the Rheum undulatum L. extracts have an functional material for inflammatory activities.
In this study, the effect of probiotic supplementation on growth performance, blood metabolites, and meat quality of Hanwoo steer was investigated. A total of 32 Hanwoo steers (15-17 months, average body weight $462{\pm}37.9kg$) were randomly allotted to 4 dietary treatments (0, 0.5, 1.0, and 1.5% mixed probiotics), with four Hanwoo steers per pen (two replicates per treatments), and reared for 12 months. There were no differences among treatments in growth performance of Hanwoo steer (P>0.05); however, feed intake decreased linearly with increasing levels of mixed probiotics. Growth hormone and Blood Urea Nitrogen (BUN) levels responded linearly with increasing levels of dietary mixed probiotics (P<0.05), but not insulin and blood glucose did not. In particular, total cholesterol was significantly lower for the 1% mixed probiotic treatment in comparison with that of the other treatments (P<0.05). The pH, Thiobarbituric Acid Reactive Substances (TBARS), cooking loss, and meat color were influenced by increasing levels of mixed probiotics (P<0.05), but the carcass characteristics and shear force were not. Regarding sensory evaluation, the addition of mixed probiotics resulted in significant difference in meat color, tenderness, aroma, off-flavor, juiciness, and marbling score, but not in overall acceptability. In addition, fatty acid profiles indicated no differences between control and mixed probiotic treatments. In conclusion, mixed probiotic treatment at 1% levels can enhance consumer preferences possibly by reducing cholesterol and TBARS.
