Intussusception is a common disease cause of intestinal obstruction in between ages 6 and 36 months. While idiopathic intussusception is most common in children, traumatic intussusception is rare. A recent review of the English literature reported 22 cases of intussusception caused by abdominal trauma, with only 7 cases in preadolescents. Because typical presentation of sudden onset of intermittent severe, cramp, progressive abdominal pain, vomiting, rectal bleeding, and sausage-shaped abdominal mass are unusual in traumatic intussusceptions, we need to pay more attention to avoid delayed diagnosis. A 3-year-old girl was admitted to the emergency department after a bicycle accident occurred one day before. The abdominal pain was initially tolerable but progressively worsened. On initial examination, she complained of diffuse abdominal pain but had not vomiting or diarrhea. Except for this, physical examination was normal without fluid collection on focused assessment with sonography for trauma (FAST) examination. We consulted general surgery and pediatrics, and requested radiology for abdominal ultrasonography. Ileocolic intussusceptions was found, and air reduction was performed successfully. She was hospitalized to the pediatric ward for observation. Two days later the patient was discharged to home without relapse or complication. The underlying mechanism of traumatic intussusception is unknown but has been proposed to be either a pathological peristaltic wave, localized spasm of bowel segment, an intramural hematoma or edema after the trauma. The present case had no history of abdominal disease and no structural abnormalities such as bowel wall edema and hematoma, so we suggested that the cause was due to pathological peristalsis or localized spasm. In past studies, intussusceptions occurred most often near the ileo-ileal (4 cases) or jejuno-ileal (3 cases) bowel segments, however, the present case occurred ileo-colic segment. In clinical manifestations of traumatic intussusception, abdominal pain, nausea or vomiting were a common symptoms. On the other hand, hematochezia and palpable abdominal mass presented in less than half. Although ultrasonography is the method of choice of detect intussusception (sensitivity 98- 100%), FAST, performed by emergency physician, does not examine bowel. So there is a possibility of misdiagnosis for intussusception, unless we pay attention to abdominal pain. Traumatic intussusceptions are usually treated with surgery, however, in this case we treat with air reduction.
The purpose of this study was to evaluate the effect of balance training on gait stability. The study population included 17 male high school students who were divided into 3 groups, each of which underwent one of the following types of balance-training programs for 8 weeks: 1 foot standing on cushion foam, trunk muscle training, and inverted body position training. 0, 4, and 8 weeks, the following experiment was performed: The participants were asked to close their eyes and take 17 steps; the stability of forward and sideward movement was determined, and the direction linearity was measured. The results revealed that all the training programs caused a decrease in stride deviation and an increase in the and the stride length, thereby improving the stability of forward movement. All the programs decreased the variation in step width and were thus also effective in improving the stability of sideward movement. The inverted body position training program was considered very effective because the cross point appeared on post hoc graphic analysis after 4 weeks, and the deviation length for 10 m was low, i.e., below 4 cm. All the programs were effective with respect to direction linearity because they decreased the deviation in direction widths. The results indicate that whole-body neurocontrol training is more effective than simple muscle training and local focused balance training, although this neurocontrol training-in the form of inverted body position training-required a longer training period than did the other programs.

The cell viability by XTT assay, DPPH-radical scavenging activity, superoxide dismutase (SOD)-like activity and lipid peroxidation were measured to evaluate the cell injury of chromium trioxide (CrO3) and the antioxidative effect of lavender (Lavendula angustifolia L.) oil on the cell injury induced by CrO3 in cultured C6 glioma cells. C6 glioma cells were then treated with the media containing 30~50 μM of CrO3 for 48 hours. The results of this study showed that CrO3 remarkably decreased cell viability in dose-dependent manner and the XTT50 value was appeared at 40.5 μM of CrO3. In the effect of antioxidant, SOD on CrO3-mediated cytotoxicity significantly increased the cell viability which was decreased by CrO3. Meanwhile, in the protective effect of lavender oil on the cytotoxicity induced by CrO3, it remarkably increased the cell viability damaged by CrO3-mediated cell injury and also showed the DPPH-radical scavenging activity, SOD-like activity and the inhibitory activity of lipid peroxidation. From these results, it is revealed that the cell injury by CrO3 was involved in oxidative stress and lavender oil was effective in the protection of CrO3-mediated cell injury by antioxidative effect.
To clarify the oxidative stress of reactive oxygen species (ROS) and the effect of Chrysanthemum morifolium L. (CM) flower extract on the cultured neuroglial cells (C6 glioma) damaged by ROS, cell adhesion effect was measured by colorimetric assay after cultured C6 glioma cells were treated with various concentrations of glucose oxidase (GO) for 5 hours. For the antioxidative effect of CM flower extract, cell adhesion activity (CAA), superoxide dismutase (SOD)-like activity and lactate dehydrogenase (LDH) activity were assessed against GO-induced cytotoxicity on same cultures. In this study, GO remarkably decreased CAA dose-dependently, and the XTT90 and XTT50 values were measured at 15 mU/mL and 50 mU/mL following the treatment of C6 glioma cells with 5∼60 mU/mL of GO. The CM flower extract significantly increased cell adhesion activity damaged by GO-induced cytotoxicity, and it also showed the SOD-like activity and the decrease of LDH activity. From these results, it is suggested that GO was cytotoxic on cultured C6 glioma cells, and CM flower extract showed antioxidative effects as shown by the increased CAA, SOD-like activity and the decrease of LDH activity on GO-induced cytotoxicity on the same cultures.
We determined intravitreal levels of vascular endothelial growth factor (VEGF) and pigment epithelium derived factor (PEDF) in patients with early phase rhegmatogenous retinal detachment (RRD). Twenty five eyes of 25 RRD patients with symptom onset from one day to 21 days prior to vitrectomy were selected. Concentrations of VEGF and PEDF in vitreous were determined by enzyme-linked immunosorbent assay and relationships between these concentrations and durations and involved quadrants were analyzed. Duration of RRD was found to show significant correlation with PEDF concentration. However, number of involved quadrants did not show correlation with PEDF concentration in vitreous.
To evaluate the physioactivity of Salicornia herbacea L. (SH), which are obtained from Sunchon bay as wild plants, an SH extract was prepared by freeze drying to obtain SH, and by cold drying to obtain SH. For the evaluation of their bioactivities, cell viability and antioxidative effect were measured. The XTT assay was adopted to measure cell viability after C6 glioma cells were treated with various concentrations of reactive oxygen species (ROS) and hydrogen peroxide (H2O2) for 8 hours. The DPPH-radical scavenging activity was also measured for the antioxidative effect. In this study, the XTT50 value of H2O2 was determined at 30 μM which was highly toxic based on the cytotoxic criteria by Borenfreund and Puerner. The protective effect of SH extract significantly increased cell viability compared with H2O2-treated group. Its antioxidative effect showed a significant DPPH-radical scavenging activity at concentrations of 1-100 μg/mL, while SH extract showed highly a DPPH-radical scavenging activity at only 100 μg/mL. From these results, H2O2 was highly toxic in cultured C6 glioma cells, and SH extract was effective in the prevention of cell damage by its antioxidative effect.
