Objective: The decision to adopt a conservative or surgical modality for a relatively small volume of spontaneous intracerebral hemorrhage (SICH) is difficult and often controversial, especially when consciousness is tolerable. The authors examined the results of stereotactic-guided evacuation of SICH for relatively small volumes with respect to functional outcome. Methods: This prospective study was performed on 387 patients with SICH who underwent stereotactic-guided evacuation (n = 204, group A) or conservative treatment (n = 183, group B) during the past 8 years. The primary end-point was recovery of functional status, which was estimated using the Modified Barthel Index (MBI) and the modified Rankin Scale (mRS). Results: All patients had a Glasgow coma scale (GCS) score of $\geq$ 13 and unilateral hemiparesis of less than motor power grade 3. Group demographic characteristics and initial neurological statuses were similar. In all cases, the volume of SICH involved was < 30 cm$^3$ and location was limited to basal ganglia and thalamus. At 6-month follow-ups, MBI was 90.9 in group A and 62.4 in group B (p < 005), and MRS was 1.2 in group A and 3.0 in group B (p < 0.05). Better motor function and stereotactic-guided evacuation had a significant effect on a functional recovery in regression analyses. Conclusion: Even in patients with a small volume of SICH, stereotactic-guided evacuation improved functional recovery in activities in daily life than conservative treatment did.

Stroke is a major cause of death and long-term disability. Because muscle weakness is one of the most prominent consequences of stroke, it was considered important to determine whether exercise in order to improve muscle strength and range of motion could have an effect in limiting the learned disuse of the affected side. The purpose of the study was to identify the effects of an 8 week rehabilitation program on physical and cognitive ability in stroke patients. A total of 18 patients who were admitted to the oriental medicine unit of a K medical center in Seoul were recruited : ten for the experimental group and eight for the control group. The rehabilitation program consisted of three level's of active and passive exercises for prevention of muscle contracture and at range of motion. Muscle strength, flexibility of the upper and lower extremity, perceived balance, functional independence, depression, and quality of life for the two groups were compared at the pretest and 4 and 8 weeks after the rehabilitation program. The results are as follows : 1) When measuring muscle strengths of shoulder abduction and elbow flexion, hip flexion and knee extensor, ankle dorsi-flexor and muscle strength of knee flexor. Muscle strength of knee flexor for the experimental group was significantly higher than the comparison group at the 4 weeks. 2) Muscle strength and flexibility of the ankle dorsi -flexor for the experimental group was significantly better than for the control group at 8 weeks. 3) Functional independence, perceived balance, and Tinetti balance for the experimental group as measured at 4 and 8 weeks were better than for the control group. Also, there were changes over time in physical balance and functional ability, but there was no significant differences between the groups. 4) The experimental group showed a higher quality of life and lower depression than the control group at 8 weeks. 5) Muscle strength and flexibility of ankle dorsi -flexor were significantly changed over time and an interaction between group and time. The findings suggested that the rehabilitation program would improve the physical and psychological status of the stroke patients. Thus, the gains in actual or perceived ability to perform physical activities was marked.

We investigated the anti-diabetic activity and enzymatic activity of 24 commercial doenjang samples certified for traditional foods. Twenty four doenjang samples showed the wide ranges in enzymatic activities (protease activities 0-50.45 unit/g, ${\alpha}$-amylase activities 0-675.9 unit/g, ${\beta}$-amylase 13.6-308.6 unit/g), and there were no difference in enzymatic activity by the producing region. To evaluate the potential anti-diabetic activity of 24 doenjang samples, we examined the effect of doenjang methanol extract (DME) on 2-[n-(7-nitrobenz-2-oxa-1, 3-diazol-4-yl) amyno]-2-deoxy-d-glucose (2-NBDG) uptake. Ten samples among 24 samples significantly stimulated the uptake of 2-NBDG. When the cells were treated with DME at 400 ug/mL, No. 17 and 23 specially stimulated 2-NBDG uptake by 1.23-fold and 1.25-fold, respectively, compared with untreated control cell. And there were no cytotoxicity in the C2C12 cells treated with DME at concentration of 500 ug/mL. Among 24 samples, No. 6, 7, 12, 21 and 24 showed the ${\alpha}$-glucosidase inhibitor activity at concentration of 10 mg/mL; however, they were less effective than acarbose which is a commercial ${\alpha}$-glucosidase inhibitor.

Purpose: The aim of the current study was to investigate EMG activity on dynamic balance of subjects with functional lumbar instability following fatigue of low back. Methods: The subjects (24 university students) were divided into 2 groups; functional lumbar instability group (6 males and 6 females) and lumbar stable group (7 males and 5 females) who could complete a questionnaire and undergo a prone instability test. All participants were evaluated for distribution of muscle activity using the TeleMyo DTSTM system. Dynamic balance was tested by Y balance test. This study was conducted for measurement of EMG activity on dynamic balance with the difference between FLIG and control group following muscle fatigue. Results: The functional lumbar instability group (FLIG) showed a significantly lower YBT score (%) of anterior, posterolateral direction on Y-balance test (YBT) in dynamic balance than the lumbar stable group (LSG) (p<0.05). The FLIG was significantly lower than the LSG in anterior direction in EMG activity(%) of MF, RA, ES, GMX, GME, RF, and posteromedial direction in EMG activity(%) of IO, ES and then posterolateral direction in EMG activity(%) of IO, ES in dynamic balance (p<0.05). There was significant correlation of MF, RA, and GMX in anterior reach direction (p<0.05) and ES, GME (p<0.01) and IO, ES in posteromedial reach direction (p<0.05) and EO, ES, GMX in posterolateral reach direction (p<0.05) there was positive correlation. Conclusion: This study showed that FLIG effected EMG activity by dynamic balance following muscle fatigue. Further study is needed for measurement of various ages and work with lumbar instability for clinical application.

Purpose: This study investigated the effects of proprioceptive neuromuscular facilitation (PNF) exercise on the range of motion (ROM), pain, and functional activity of patients who received total knee arthroplasty (TKA). The purpose of this study was to provide fundamental data regarding the use of PNF exercise among patients with musculoskeletal disease. Methods: Fourteen patients who received TKA were randomly divided into an experimental group (n=7) that took part in PNF exercise and a control group (n=7) that performed general rehabilitation exercise. Both groups performed the respective exercises for 30 minutes, five times a week for 2 weeks. For the measurement of ROM, the range of knee flexion was measured using a clinometer smartphone application. A visual analogue scale (VAS) was used for the measurement of the level of pain. The timed up and go test (TUG) was conducted to measure functional activity. A paired t-test was performed to compare within-group changes before and after the PNF exercise. Differences between the experimental group and control group were analyzed by an independent t-test. For all tests, the level of statistical significance was set at ${\alpha}=0.05$. Results: After the exercise, there was a significant within-group change in VAS and TUG scores in the experimental group and control group (p<0.01). There was also a significant between-group difference in VAS and TUG scores after the intervention (p<0.05). Conclusion: General rehabilitation exercise is commonly applied as a treatment for TKA patients and is relatively effective. The application of PNF exercise may be useful in such patients, considering its effects on ROM improvement, pain reduction, and functional enhancement.

In the 21st century, the development of cosmetics is led to pursue the high functionality of cosmetics with excellent effectiveness and safety. As Cosmetic Act took effect in 2000, functional cosmetics is provided in the law. As a result, the research and development of functional cosmetics has continually increased, and the number of patent applications in functional cosmetics has also rapidly increased as a plan for preoccupying in the functional cosmetics age. Now, the cosmetic industry has a great interest in developing anti-wrinkle cosmetics among functional cosmetics, because women's desire for having young resilient skin has increased since Korea entered an aging society thanks to the advanced medical technology. The patent application trends of anti-wrinkle cosmetics at home since 2000 particularly show the rapid increase in the applications in natural plant extracts. It may be because Korean consumers preference of vegetable cosmetics has resulted in the development of raw materials based on the traditional medicine. As for the existing preparation such as Retinoid or Ascorbic acid, the patent application itself will be an essential technical element in the future because patent applications are filed in the field of a preparation of cosmetics for stabilizing ingredients, reducing skin irritability or promoting absorbance, and in the field of cosmetic formulation technology. As there are many studies on the causes of skin wrinkles, it is expected that new raw materials of cosmetics can be developed due to new mechanisms, and that the number of patent applications in new technologies will increase due to a change in the thought of cosmetics accompanied by the integration of cosmetics with biotechnology using Genetic Engineering, including the practical application of the medicine previously used far treating skin diseases to an anti-wrinkle agent and the mass production of active ingredients of cosmetics.

Hot water extracts of Camellia japonica flower buds were found to have the higher 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity than the other solvent extracts. Five phenolic compounds were isolated and purified from the ethyl acetate soluble-neutral fraction of hot water extracts by Sephadex LH-20 column chromatography and octadecyl silane-high performance liquid chromatography using the guided assay of DPPH radical scavenging. Based on mass spectrometer and nuclear magnetic resonance, the isolated compounds were identified as p-hydroxybenzaldehyde (1), vanillin (2), dehydroxysynapyl alcohol (3), 7S,7'S,8R,8'R-icariol $A_2$ (4), and (-)-epicatechin (5). Four compounds (1-4) except for 5 were newly identified in this plant. Their DPPH radical scavenging activities as 50% scavenging concentration decreased in order to 5 $(20\;{\mu}M)>{\alpha}-tocopherol$ $(29\;{\mu}M)>4$ $(67\;{\mu}M)>3$ $(72\;{\mu}M)>1=2$ ($>250\;{\mu}M$). These results indicate that the antioxidant effect of the hot water extract of C. japonica flower buds may partially due to 5 isolated phenolic compounds.
