  • Treadmill training is a new promising therapy in gait rehabilitation of patients with hemiplegia. The purpose of this study was to identify the effect of treadmill training on walking speed and gait endurance in patients with chronic hemiplegia. The subject of this includes twenty patients, who had suffered from chronic hemiplegia and were in the K rehabilitation center; each ten patients were randomly assigned to experimental or control group. Among twenty patients, one group of ten for experiment was treated with progressive speed increase treadmill ambulation traing besides conventional physical therapy(SITAT) while the rest ten for the controlled group was treated with conventional physical therapy(CPT) only, for 8 weeks alike. Before and after the foregoing 8 weeks training, walking velocity and gait endurance were measured to both groups. The data were analyzed by paired t-test. The results of this study are as follows; The SITAT and CPT showed the significant difference in walking velocity and gait endurance. As compared the rehabilitation of dependent varibles between the SITAT and CPT, SITAT showed the significant difference in walking velocity and gait endurance. The outcome suggest that patient with chronic hemiplegia can improve their walking velocity and gait endurance throught treadmill training.

  • Purpose: This study aimed to assess the quality of dental prostheses printed by digital light-processing (DLP) technology. Methods: Ten experimental models were prepared. The ten specimens that were printed by DLP technology constituted the DLP group. The ten specimens that were produced in the same model by the casting method constituted the control group. The marginal gaps of the 20 specimens produced were measured. These gaps were measured by a silicon replica technique at two abutments of the specimen. Therefore, 20 marginal gaps were measured in each group. An independent sample t-test was performed to compare the marginal gaps measured in the two groups (α=0.05). Results: According to the results of the measurement, there was a significant difference between the mean marginal gap of the control group (78.8 ㎛) and that of the DLP group (91.5 ㎛), p<0.001. Conclusion: Although the mean marginal gaps of dental fixed prostheses produced by the DLP method was higher than the mean marginal gap of those produced by the casting method, it was considered to be within the clinical threshold value suggested by some previous studies.

  • Objective: The purpose of this study was to analyze the correlation between Stomach Qi Deficiency and gastric emptying as measured by abdominal ultrasonography in postprandial distress syndrome (PDS), a subgroup of functional dyspepsia (FD). Methods: Ten patients who met the Rome III diagnostic criteria for PDS and ten healthy controls participated in this study Gastric emptying shown as the half-life of gastric volume ($T_{1/2}$) was measured by abdominal ultrasonography. The degree of Stomach Qi Deficiency was assessed using the scale for Stomach Qi Deficiency pattern (SSQD). In addition, functional dyspepsia-related quality of life (FD-QoL), Nepean dyspepsia index-Korean version (NDI-K), and visual analogue scale (VAS) of distention and fullness were conducted on all subjects. Results: The scores of SSQD, FD-QoL, NDI-K, and VAS of distention and fullness in the patient group were significantly higher than those in the control group (p<0.05). $T_{1/2}$ was also higher in the patient group than in the control group. The SSQD score significantly correlated positively with $T_{1/2}$ in the patient group (r=0.640, p=0.046). However, there was no significant correlation between $T_{1/2}$ and other questionnaire scores in the patient group. Conclusions: Our results suggest that the gastric emptying measured by abdominal ultrasonography could be a quantitative indicator to diagnose Stomach Qi Deficiency in FD patients, especially the PDS subtype.

  • Evaluate the triolein emulsion could disrupt the barriers and to suggest as an experimental model in blood-ocular barrier studies. Triolein emulsion was infused into the carotid artery in the experimental group ten cats. Normal saline was used in another the control group ten cats. Pre contrast and postcontrast T1-weighted MR images were obtained at 30 minutes and 3 hours after embolization. Signal intensities were evaluated in the anterior, posterior chamber and in the vitreus qualitatively and quantitatively. Postembolization 30 minutes MR images were not different from those of the control group. Postembolization 3 hour MR images demonstrated delayed contrast enhancement in the anterior chamber of the ipsilateral and contralateral eyeballs and in the posterior chamber of the ipsilateral eyeball. Delayed contrast enhancement of the posterior chamber of the ipsilateral eyeball was statistically significant (P<0.05). The present study demonstrated significant contrast enhancement in the posterior chamber with infusion of triolein emulsion and can be a model in blood-aqueous barrier studies.
