  • Objectives : To clarify the possible effect of JS (Juglans sinensis), PCF (Psoralea corylifolia L.), and J+P(JS+PCF), we examined their influence on the development of pulmonary eosinophilic inflammation in the asthmatic murine model. Methods : All mice were immunized on two different days (21 days and 7 days before inhalational exposure) by intraperitonial injections of 0.2 ml alum-precipitated Ag containing 100 ${\mu}$g of OVA bound to 4 mg of aluminum hydroxide in PBS. Seven days after the second sensitization, mice were exposed to aerosolized ovalbumin for 30 minutes/day on 3 days/week for 8 weeks (at a flow rate of 250 L/min, 2.5% ovalbumin in normal saline) and, JS, PCF and J+P (200 mg/kg, 400 mg/kg) were orally administered 3 times per week for 8 weeks. Results : The suppressive effects of JS, PCF, and J+P were demonstrated by the accumulation of eosinophils into airways, with the reduction of eosinophils and lung leukocytes. These were correlated with the marked reduction of IL-4, IL-5, IL-13 levels in the BALF and serum. OVA-specific IgE levels were also decreased in serum and BAL from these mice. And also JS, PCF, and J+P decreased eosinophilic CCR3 and CD11b expression in lung tissue. Conclusions : These results indicate that JS, PCF, and J+P have deep inhibitory effects on airway inflammation and hyper-responsiveness in the asthmatic murine model. The suppression of IL-5, IgE, and eosinophilils and the increase of IFN-${\gamma}$ production in BALF seem to contribute to these effects. Specially, esosinophils and TNF-a in J+P combination group were significantly reduced in BALF and lung tissue. Hence, the results indicated that JS, PCF, and J+P could act as an immuno-modulator which possesses anti-inflammatory and anti-asthmatic property by modulating the imbalance between Th1 and Th2 cytokines.

  • Objectives : The purpose of this study was to investigate the effect of Poncirus Trifoliata(PT) on improvement of fecal impaction in spinal cord injured(SCI) rats. Methods : Fifteen adult Sprague-Dawley female rats were used weighing 200~250 g. A complete spinal cord transection was performed surgically at the T10 cord level. Experimental groups were assigned into 3 groups: Control(n=5), SCI+vehicle(n=5) and SCI+PT(n=5). PT was administered 100mg/kg in 0.5ml every 24 hours from 1st operation day to 7th day. We measured the body weight and food intake as well as the number and the weight of fecal pellet every morning. After 1 week of operation, whole colon was divided into proximal and distal segments under anesthesia. Each segment of colon was mounted with longitudinal direction in a organ bath. We measured spontaneous contraction and compared the area under the curve in each segments. Enhanced responses were observed by acetylcholine($10^{-6}M$), 40 mM KCl solution, L-NAME($10^{-4}M$). Results : The fecal number and weights were significantly higher in the group of SCI+PT than SCI+vehicle group(p<0.05). In organ bath study, area under the curves of the spontaneous contraction in SCI+vehicle and SCI+PT groups were significantly increased compared to control group. Contractility of distal colon in response to acetylcholine or KCl in SCI+vehicle group was significantly decreased compared to other groups(p<0.05). Conclusions : These results suggest that PT might be useful to promote bowel emptying in spinal cord injured rats.

  • Purpose : The study to verify the effectiveness of the Soomchi combined marine healing program by analyzing the physical composition of the subjects, their blood lipids, and the effects of the program on their lung health-related variables, and heart rate variability variables. Methods : In the experiment, the Soomchi combined marine healing program was conducted for 5 hours a day, 5 days a week. on 15 participants. The results of their body composition, blood lipids, lactic acid, blood pressure, PEF, FEV1 and maximum oxygen intake were analyzed before and after the subjects completed the Soomchi program. For the statistical analysis, the mean and standard deviation (M±SD) of each variable were calculated using SPSS version 20 and an independent t-test was conducted to test for the amount of change in the participants before and after the Soomchi combined marine healing program. All significant levels were set to α=.05. As a result of the experiment Results : First, no statistically significant differences were found in the changes in body composition after the 5-day combined marine healing program was completed. Second, regarding the changes in blood component after the program was conducted, statistically significant differences were found in the lactic acid (p<.05). That is, the experimental group showed a significant decrease in lactic acid after the program whereas the control group showed a significant increase. Third, systolic blood pressure decreased significantly and while in PEF and FEV1 increased significantly in the experimental group after the program. Fourth, the LF of the control group significantly decreased after 5 days. Conclusion : After the Soomchi Lung Health Ocean Healing Program, positive physical changes were observed in the lung health variables and heart rate variability of the participants.

  • The purpose of this study was to analyze the patterns and the interrelationships for meeting guidelines of three health behaviors including physical activity(PA), sedentary behavior(SB), and dietary behavior(DB) for Korean adolescents using 2007 KYRBS(Korea Youth Risk Behavior Survey) data. A cross-sectional design was used to assess 73392 middle-high school students. PA(moderate physical activity${\geqq}$5times/week, or vigorous ${\geqq}$3times/week), SB(watching TV, computer, DVD, video, etc. < 3 hr/day), and DB(servings of fruits ${\geqq}$1 times/day, or vegetables ${\geqq}$ 3 times/day) were categorized into two levels (meeting guidelines or not). Chi-squared tests were conducted to compare the prevalence of students not meeting these three health behaviors between boys and girls, and logistic linear regression was used to determine the interrelationships of three health behaviors. Students meeting guidelines for PA, SB, and DB were 31.0%(boys 42.6%, girls 18.0%), 74.7%(boys 75.4%, girls 74.0%), and 38.5%(boys 38.6%, girls 38.4%), respectively. In addition, there were significant differences between both genders for PA and SB (PA; $x^2(1)$=35175.11, p<.0001, SB; $x^2(1)$=19.44, p<.0001). Only 10.9% of students met all three guidelines and 12.4% did not meet all three. Pattern that simultaneously did not meet PA and DB were high in both boys(27.1%) and girls(37.2%). Students who did not meet DB were at greater risk of not meeting PA(Boys; OR 1.49, 95% CI 1.43 to 1.55, Girls; OR 1.42, 95% CI 1.34 to 1.50), and not meeting SB(Boys; OR 1.41, 95% CI 1.34 to 1.48, Girls; OR 1.36, 95% CI 1.29 to 1.43) compared with students who met DB. The findings of this study supported further evidence for the need of a multiple behavior approach considering gender and interrelationships among three behaviors.

  • Objective: The purpose of this study was determine the effect of Balance Trainer training with Transcutaneous Electrical Nerve Stimulation (TENS) on spasticity and balance in persons with chronic stroke. Design: Randomized controlled trial. Methods: A total of 30 subjects with hemiparetic stroke were recruited and randomly divided into the Balance Trainer training with TENS group (n=15) and Balance Trainer training with placebo TENS group (n=15). The Balance Trainer training with TENS group practiced additional Balance Trainer training with TENS for 30 minutes a day, 5 days per a week during 4 weeks and the Balance Trainer training with placebo TENS group practiced additional Balance Trainer training with placebo TENS for the same period. Spasticity and balance were assessed by ability (static balance, dynamic balance) and were measured before and after the 4-week programs. Results: The result of spasticity and dynamic balance were improved significantly in both groups (p<0.05). The Balance Trainer training with TENS group showed significantly greater improvement in spasticity of the gastrocnemius & dynamic balance, compared to the Balance Trainer training with placebo TENS group (p<0.05). The Balance trainer training with TENS group showed a significant improvement in static balance, especially during the eye-closed condition (p<0.05). Conclusions: The Balance Trainer training with TENS was effective in improving spasticity and balance in subjects with chronic stroke. Based on these results, it is suggested that Balance Trainer training with TENS could clinically be used more actively in conjunction with conventional physical therapy.

  • Objectives : Parkinson's disease (PD) is the second most common neurodegenerative disorder worldwide and is characterized by the loss of the dopaminergic neurons in the substantia nigra (SN). In a previous in vitro study, we demonstrated that Sihogyeji-tang (SG), Sihosogan-tang (SS), and Sihocheonggan-tang (SC) have the potential to be candidate medicines for PD. This study aimed to compare the neuroprotective effect of SG, SS, and SC using 1-methyl-4-phenyl-1,2,3,6-tetrahydrophridine (MPTP)-induced PD mouse model. Methods : Eight-week-old male C57BL/6 mice were intraperitoneally administered with 30 mg/kg of MPTP for 5 days and orally administered SG, SS and SC for 12 days from the first MPTP injection. Motor function was assessed using the pole test and the rotarod test. Dopaminergic neuronal survival in the SN and striatum was evaluated through tyrosine-hydroxylase immunohistochemistry. Results : MPTP administration resulted in behavioral impairment and dopaminergic neuronal death in the SN and striatum. In the pole test, treatment with SG, SS, and SC alleviated the MPTP-induced motor dysfunction on day 5 and 12. In the rotarod test, SS and SG alleviated the MPTP-induced motor dysfunction on day 5, while only SS showed improvement on day 12. SS and SG significantly protected dopaminergic neurons in the SN from MPTP toxicity, and all three compounds (SG, SS, and SC) showed significant protection in the striatum. Notably, SS demonstrated superior efficacy in suppressing MPTP-induced motor dysfunction and dopaminergic neuronal death compared to SG and SC. Conclusions : These findings suggest that SS is the most effective formula among SG, SS, and SC for PD, indicating its potential role in the treatment of PD.

  • During below knee amputation, the amputation stump must be covered with well-vascularized and sensate soft tissue. Many flaps can be used for this purpose, but available reconstructive options are limited. We performed reverse flow ALT flap elevation on two patients with below knee amputations to reconstruct defects in the stumps. The sizes of the defects in the stumps were $4{\times}16$ cm and $5{\times}5$ cm, respectively. The most distal portion of the defects were located 20 cm and 16 cm lateral to the knee joint in a curve, respectively. The size of the elevated flap was $5{\times}18$ cm for case 1 and $18{\times}10$ cm for case 2. The respective pivot points of the pedicles were 7 cm and 6 cm above the patella and the respective lengths of the pedicles were 17 cm and 16 cm. In both cases, venous congestion occurred on the second postoperative day and the flap distal to 10 cm or more from below the knee joint was necrotized at the second postoperative week. Surgeons should be cautious when using a reverse ALT flap to reconstruct a soft tissue defect located 10 cm or more distal from below the knee joint. Since a pedicle longer than 15 cm may develop partial necrosis of the flap, simultaneous application of antegrade venous drainage is recommended.
