        This study aims to identify the effect of home physical therapy on patients who left the hospital after total knee arthroplasty, compared to the Daily living group, when it was applied to them, under the guidance of physical therapists. As research subjects, 20 patients that were scheduled to leave the hospital after unilateral total knee arthroplasty, were chosen, and they were randomly divided into a home physical therapy group(10 patients) and an Daily living group(10 patients) in order to conduct an experiment. During the 4-week research, home physical therapy was offered for 40 mins once for 5 days a week, and muscular strength, gait components were measured. For muscular strength, quadriceps muscle strength, hamstring muscle strength were measured, and as gait components, endurance, speed, step time, single-limb support were analysed. For this experiment, pre- and post-measurement were performed, and collected data were analyzed using SPSS ver. 18.0 statistical program. From the analysis of data, the following study results were obtained. Home physical therapy group and Daily living group both showed significant improvements in quadriceps muscle strength, hamstring muscle strength, and quadriceps muscle strength, hamstring muscle strength of home physical therapy group more significantly improved than Daily living group's. In relation to gait components, gait endurance, gait speed, step time significantly improved in both of home physical therapy group and Daily living group, whereas home physical therapy group only showed significant improvements in single-limp support. According to the comparison between two groups, gait speed, single-limp support and step time improved more significantly in the home physical therapy group than in the Daily living group. In conclusion, positive results were revealed in both home physical therapy group and Daily living group, with regard to muscular recovery of lower limbs of patients discharged from the hospital after total knee arthroplasty and walking, but considering the comparison results between two groups, it seems that applying home physical therapy is more effective than maintaining a daily life.

        This study was carried out to investigate the residual sulfur dioxide residues (SO2) in commercial medicinal herbs in Korea in 2013. Among a total of 116 samples of 11 different kinds of herbs, 71 samples (11 Kinds) were domestic, and 45 samples (10 Kinds) were imported. The residual contents of SO2 in the samples were determinated by a modified Monier-Williams method. Of the 116 samples, 6 samples (5.2%, 4 Kinds) failed to meet the regulations for sulfur dioxide residues of KFDA in medicinal herbs. Among 6 unsuitable samples, 1 samples (1.4%) were domestic, and 5 samples (11.1%, 3 Kinds) were imported. The highest amount of sulfur dioxide residues was 1546.3 mg/kg (Lycii Fructus) in the domestic samples. Regardless of region, SO2 contents were not found at Anemarrhenae Rhizoma, Citri Unshius Pericarpium, Eucommiae Cortex, Forsythiae Fructus, Gardeniae Fructus, Leonuri Herba and Lonicerae Folium et caulis. These data will be used as a basic data for the future legislation on the regulation and control of sulfur dioxide of herbal medicines.

        The purpose of this study was to examine the influences of chronic shoulder pain on the muscle tone in trunk muscles. The study's subjects were 40 men and women in their 30 to 50s, which were divided into two groups. A chronic shoulder pain group consisted of 20 subjects who had been diagnosed with chronic shoulder pain by doctors, and a painless group consisted of 20 subjects who had experienced no such pain. An analysis was performed using electromyography on the muscle tone in the rectus abdominalis, external oblique, internal oblique, and erector spinae muscles under the same conditions between the two groups. The analysis results were as follows. The chronic shoulder pain group exhibited an overall high level of trunk muscle tone than the painless group, along with a statistically significant difference in the rectus abdominalis(p<.05). Moreover, the chronic shoulder pain group showed differences in the trunk muscle tone depending on the affected side. The chronic left shoulder pain group yielded higher levels of muscle tone in the right-side trunk muscles. In particular, the group revealed statistically significant differences in the rectus abdominalis and internal oblique(p<.05). The chronic right shoulder pain group exhibited higher levels of muscle tone in the left-side trunk muscles with a statistically significant difference in the internal oblique(p<.05). The above results suggested that chronic shoulder pain influences increases in the muscle tone in the trunk muscles on the opposite side to the affected shoulder.

        The objective of this study was to determine the effects of E. coli isolated from porcine semen on sperm viability, motility, and semen pH. Semen samples were prepared using commercial extender, SeminarkPro (Noahbio Tech, Korea) that did not contain antibiotics. And 4 different levels of E. coli were artificially innoculated to semen with following concentrations; 4,000 of sperms with 1 of E. coli (T1), 400 with 1 (T2), 40 with 1 (T3), and 4 with 1 (T4). Semen samples were preserved at 17℃ for 5 days in semen storage box until analyzed by flowcytometer. Aliquots were subjected to measure the sperm viability (Live/Dead® stain), motility (mitochondrial function), and semen acidity (pH) from day 0 (day of semen collection) to day 5. Sperm motility and viability were significantly decreased (p<0.05) on day 0 (4 hrs after preservation at 17℃) in T3 and T4 compared to control groups and were significantly decreased (p<0.05) in all groups from day 3. Sample pH was acidic in T3 (6.90~6.86) and T4 (6.86~6.65) from day 3 to day 5 (p<0.05). On the other hand, sample pH was maintained 7.0~7.1 in control, T1, and T2 during the experimental period. Sperm motility and viability were significantly decreased from day 0 to day 5 compared to control in samples contaminated with E. coli above a value of 40:1 (20×106 sperm cells/ml : 5×105 cfu/ml). Even on day 1 in T4 and on day 3 in T3, semen pH was acidic probably due to the acidification of dead spermatozoa. These results suggest that E. coli contamination has a concentration-dependent detrimental effect on extended porcine semen quality.

        The majority of strokes are caused by ischemia and result in brain tissue damage, leading to problems of the central nervous system including hemiparesis, dysfunction of language and consciousness, and dysfunction of perception. The purpose of this study was to investigate the effects of Poly(ADP-ribose) polymerase(PARP) on necrosis in neuronal cells that have undergone needle electrode electrical stimulation(NEES) prior to induction of ischemia. Ischemia was induced in male SD rats(body weight 300g) by occlusion of the common carotid artery for 5 min, after which the blood was reperfused. After induction of brain ischemia, NEES was applied to Zusanli(ST 36), at 12, 24 and 48 hours. Protein expression was investigated using immuno-reactive cells, which react to PARP antibodies in cerebral nerve cells, and Western blotting. The results were as follows: In the cerebral cortex, the number of PARP reactive cells after 24 hours significantly decreased(p<.05) in the NEES group compared to the GI group. PARP expression after 24 hours significantly decreased(p<.05) in the NEES group compared to the GI group. As a result, NEES showed the greatest effect on necrosis- related PARP immuno-reactive cells 24 hours after ischemia, indicating necrosis inhibition, blocking of neural cell death, and protection of neural cells. Based on the results of this study, NEES can be an effective method of treating dysfunction and improving function of neuronal cells in brain damage caused by ischemia.

        We report relative proper motion measurements of H2O masers in massive star-forming region W51 Main, based on data sets of VLBI observations for H2O masers at 22 GHz with Japanese VERA telescopes from 2003 to 2006. Data reductions and single-beam imaging analysis are to measure internal kinematics of maser spots and eventually to estimate the three-dimensional kinematics of H2O masers in W51 Main. Average space motions and proper motion measurements of H2O masers are given both graphical and in table formats. We find in this study that W51 Main appears to be associated with hyper-compact H II region with multiple massive proto-stars whose spectral types are of late O.

        Background : Haskap berries commonly refer to fruits of Lonicera caerulea L., recognized by the Japanese aborigines as the “The elixir of life.”. Due to their recent arrival on the North American market, haskap berries have not yet been positioned among other berries and compared in terms of their phytochemical content. And haskap berries have higher ascorbic acid and anthocyanin content than other berries known for their health-promoting benefits, such as blueberries. However, no study has reported on the antioxidant and anti-cancer activity of Lonicera caerulea stem. The purpose of this study is to present the current research on the chemical content, antioxidant and anti-cancer activities of Lonicera caerulea stem. Methods and Results : The stem of Lonicera caerulea L. ware dried in the shade at room temperature and extracted with 100% methanol. The extract was suspended in deionized water and partitioned sequentially with n-hexane, chloroform, ethyl-acetate and butanol (water saturated BuOH) fractions. Antioxidant activities were measured by determination of antioxidants, DPPH (2,2-diphenyl-1-picrylhydrazyl). Cell viability was determined by the MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide] assay. All cell lines were purchased from the Korean Cell Line Bank (Seoul, Korea). All results were performed with three replications were processed statistically. By DPPH assay, the Lonicera caerulea L. the highest activity was obtained from the ethyl-acetate fraction (IC50=15.46 ㎍/㎖). By MTT assay, the chloroform fraction showed a significant growth inhibiting effect on MCF-7 (Human breast cancer, IC50=225.91 ㎍/㎖), COLO 205 (Human colon cancer, IC50=179.55 ㎍/㎖), but on AGS (Human stomach cancer) and other fractions it did not show effect. Conclusion : We demonstrated that Lonicera caerulea L. stem extract and fractions has antioxidant and antiproliferation activity in vitro. Further studies should identify the active constituents in Lonicera caerulea L stem to evaluate the potential in vitro antioxidant and antiproliferation activities of the extract.

        Collected germplasms of five representative species belonging to Curcuma genus (C. longa, C. aromatica, C.zedoaria, C. phaeocaulis and C. kwangsiensis) were 52 samples from different farmhouse in Korea and China. To elucidatethe genetic diversity among the species, 52 samples were analyzed by genomic fingerprinting method using amplified frag-ment length polymorphism (AFLP). AFLP results of 6 primer combinations were revealed 643 total DNA fragments and349 polymorphic bands with the 54.3% ratio of polymorphism. In the analysis of coefficient similarity using unweight pairgroup method with arithmetic averages (UPGMA), 52 Curcuma germplasm lines were ranged from 0.60 to 0.99 and clus-tered distinct five groups according to the species and collected geographical levels. However, the result of principal coordi-nate analysis (PCA) by multi-variate analysis was shown significantly greater differences among species than geographicalorigins based on AFLP profiling data of these samples.

        Plant biomass is a huge carbon-complex that has potential as a nutrient. Therefore we extracted and separated useful materials for plant growth from tea leaf and stem. The pre-treatment process including high temperature (200 °C) and pressure (20-40 kgf/cm2) was treated for several minutes and extracted at 120 °C for 30-60 minutes. After that the chemical compositions and ingredients were analyzed from that plantnutrient. As a result of mineral contents, calcium and magnesium concentrations are higher than other minerals. Also the result of carbohydrates analyses has shown that the sugar oligomer consists of xylose(95.3%) and glucose(4.7%), and the sugar monomer consists in the order of xylose (52.7%) > manose (22.8%) > arabinose (10.8%) > galactose (10.2%) > glucose (3.5%). Before applied to field, in vitro plant growth system and formulation were examined. To evaluate the effect of the nutrients, both strawberry green-house and persimmon fields were used in this test. The treated persimmons were heavier than controls scored at 13-22%. In addition, the storageperiod was extended in the treated strawberries. Interestingly in the treated strawberry, the contents of polyphenols were increased (38-57%). These results suggest that the plant-nutrient can afford to help for plant growth and storage, and it can be substituted for other commercial nutrients. In conclusion, this plant-nutrient may help to extend eco-friendly or organic farming in Hadong-gun area.
