1. Objectives: The purpose of this study is to investigate the effect of Suhwagije-tang(SGT) distillate on the immune activity of spleen cells of aged SD rats. 2. Methods: We used 10, 50, 72 weeks old SD rats in this study. Spleen cells from SD rats were stimulated with ConA and treated with 1% Vitamin C(Vit.C) or Suhwagijetang distillate(SGT). After 24 hours, the concentrations of IL-2, IL-4, IL-10, IFN-${\gamma}$ in the cell culture supernatant were measured by ELISA. 3. Results and Conclusions 1) At all concentration of SGT distillate, survival rates of liver cells were higher than the control group. In addition, 50% SGT distillate group's cell survival rates were significantly higher than other groups. 2) In 10 weeks SD rats(SGT group), the concentration of IL-2 significantly decreased in comparison with ConA group, Vit.C group. In 52 weeks SD rats(SGT group), the concentration of IL-2 significantly decreased in comparison with ConA group. 3) In 10, 52 weeks SD rats(SGT group), the concentration of IL-4 significantly decreased in comparison with ConA group. 4) In 10 weeks SD rats(SGT group), the concentration of IL-10 significantly decreased in comparison with ConA group. And in 72 weeks SD rats(SGT group), the concentration of IL-10 significantly increased in comparison with Vit.C group. 5) In 52, 72 weeks SD rats(SGT group), the concentration of IFN-${\gamma}$ significantly decreased in comparison with 10 weeks SD rats(SGT group). These results suggest that Suhwagije-tang(SGT) distillate has the effect of increasing the immune activity of spleen cells of aged SD rats.

Objectives : This study was performed to investigate the effect of water extracts from Lagocephalus wheeled with several herbs(LW) on hyperlipemia and liver damage induced by alcohol. Methods : Except for the normal group, we fed rat on 25% alcohol for 55 days. And each extract was administrated for the same period. We measured the serum component in rat's blood, body weight and weight of liver. Results : At first, we observed effects of LW on hyperlipemia induced by alcohol. LW group didn't show significant increase of total cholesterol in comparison with those of the control group. LW group didn't show significant increase of HDL(High-Density lipoprotein) cholesterol in comparison with those of the control group. LW group showed significant decrease of triglyceride in comparison with those of the control group. LW group showed significant increase of body weight in comparison with those of the control group in 4weeks and 8weeks. LW group showed significant increase of liver weight in comparison with those of the control group. At second, we observed effects of LW on liver damage induced by alcohol. LW group showed significant decrease of ALP, GOT, GPT and LDH in comparison with those of the control group. Conclusions : Reviewing these experimental results, it appears that water extracts from Lagocephalus wheeleri with several herbs have pharmaceutical efficacy on hyperlipidemia and liver damage induced by alcohol.

Purpose : The purpose of this study was to investigate the impact of postural correction training on pulmonary function on 28 college students suspected of turtle neck syndrome, and the following conclusions were obtained. Methods : Turtle neck syndrome suspicion 28 person were randomly divided into a posture training group (n = 14) and group that does not perform posture training (n = 14). Respiratory function was measured by SPIROVIT SP-1 and respiratory gas analyzer. The posture training group performed balloon blowing and stair climbing after 20 minutes of posture training, and the group without posture training carried out balloon blowing training and stair climbing. Five times a week and for two weeks. Results : 1. The comparison of the FVC before and after experiments caused by balloon blowing showed a higher level of effortful pulmonary function in the control group than in the experimental group. 2. Comparison of PEFs before and after the experiment by balloon blowing showed that the experimental group's peak flow rate was higher than that of the control group. 3. Comparison of the FIVC before and after experiments with balloon blowing showed that the comparison of the FIVC showed a higher level of effortless intake pulmonary function in the control group than in the experimental group. 4. The comparison of the maximum ventilation volume(VE) before and after the experimental gas measurement showed that the maximum ventilation rate of the experimental group was higher than that of the control group. 5. The comparison of pre-test and post-test heart rate(HR) by breath gas measurement showed that the heart rate of the control group was higher than that of the experimental group. Conclusion : the results of this study showed that postural correction training, balloon blowing training, and stair climbing could have a positive impact on improving pulmonary function. However, the two-week experiment conducted five times a week showed an increase in pulmonary function, but it was difficult to see the effect due to the short study period. Therefore, it is hoped that later studies will be conducted more systematically on the effects of breathing exercises on improving pulmonary function after post-postural correction training for patients with pulmonary function problems.

Purpose : This study aimed to investigate the effects of dual-task training according to the variability of the walking environment on balance, gait, and function in patients with stroke. Methods : Twenty-five patients with stroke were randomly assigned to experimental group I (n=12) and experimental group II (n=13). Experimental group I and II performed obstacle and non-obstacle walking training, respectively, along with cognitive tasks for 21 minutes per session, 3 times a week for 6 weeks. Both groups received additional general physical therapy for 30 minutes per session. The functional reach test (FRT), gait analyzer (G-Walk), and functional independence measure (FIM) were used to evaluate balance, gait and function of pre- and post-interventions, respectively, while gait cadence, gait velocity, and stride length were evaluated using a gait analyzer. Results : In the within-group comparison of FRT, all the two groups showed significant post-intervention improvements (p<.05). In within-group comparison of gait cadence, all the two groups showed significant post-intervention improvements (p<.05). In within-group comparison of gait velocity, all the two groups showed significant post-intervention improvements (p<.05). In within-group comparison of stride length, experimental group I showed significant post-intervention improvements (p<.05), while experimental group II did not show significant post-intervention improvements (p>.05). In within-group comparison of FIM scores, experimental group I showed significant post-intervention improvements (p<.05), while experimental group II did not show significant post-intervention improvements (p>.05). There was a significant difference in the change of FIM scores pre- and post-intervention (p<.05) in the between-group comparison. Conclusion : The results of this study show that dual-task training with cognitive tasks and walking training can improve the balance, gait and function of patients with stroke, and obstacle walking training is effective for improving functions including activities of daily living compared to non-obstacle walking training.

Background: The purpose of this study was to investigate the effects of pulsed-ultrasound intervention and continued-ultrasound on the PPT (pressure pain threshold), CK (creatine kinase) and LDH (lactate dehydrogenase) recovery of before EIMD (exercise-induced muscle damage). Design: Randomized Controlled Trial. Methods: Thirty subjects who are student in their 20s at a university participated in this study, these subjects were assigned into three groups, a control group (n=10), experiment group I (n=10), and experiment group II (n=10). The subjects in experimental group were intervened by pulsed-ultrasound and continued-ultrasound, while ones on control group weren't by any intervention after induced EIMD. Results: First, In the comparison of the PPT, there were significant variations with the lapse the time in three groups (p<.001) and there was a significant interaction of time and group (p<.001). In the among group comparison, the PPT of experimental group II was significantly larger than those of other groups (p<.01). Second, In the comparison of the CK, there were significant variations with the lapse the time in three groups (p<.001) and there was a significant interaction of time and group (p<.001). In the among group comparison, the CK of experimental group II was significantly smaller than those of other groups (p<.001). Third, In the comparison of the LDH, there were significant variations with the lapse the time in three groups (p<.001) and there was a significant interaction of time and group (p<.001). In the among group comparison, the LDH of experimental group II was significantly smaller than those of other groups (p<.001). Conclusion: The above results revealed that the continued-ultrasound intervention before an exercise had a positive effect of muscle function after EIMD. Therefore we can consider the continued ultrasound as a considerable intervention method to prevent or reduce an exercise injury.
