<P>This study compared the efficacy of DA-9601 (Dong-A ST Co., Seoul, Korea) and its new formulation, DA-5204 (Dong-A ST Co.), for treating erosive gastritis. This phase III, randomized, multicenter, double-blind, non-inferiority trial randomly assigned 434 patients with endoscopically proven gastric mucosal erosions into two groups: DA-9601 3 times daily or DA-5,204 twice daily for 2 weeks. The final analysis included 421 patients (DA-5204, 209; DA-9601, 212). The primary endpoint (rate of effective gastric erosion healing) and secondary endpoints (cure rate of endoscopic erosion and gastrointestinal [GI] symptom relief) were assessed using endoscopy after the treatment. Drug-related adverse events (AEs), including GI symptoms, were also compared. At week 2, gastric healing rates with DA-5204 and DA-9601 were 42.1% (88/209) and 42.5% (90/212), respectively. The difference between the groups was −0.4% (95% confidence interval, −9.8% to 9.1%), which was above the non-inferiority margin of −14%. The cure rate of gastric erosion in both groups was 37.3%. The improvement rates of GI symptoms with DA-5204 and DA-9601 were 40.4% and 40.8%, respectively. There were no statistically significant differences between the two groups in both secondary endpoints. AEs were reported in 18 (8.4%) patients in the DA-5204 group and 19 (8.8%) in the DA-9601 group. Rates of AE were not different between the two groups. No serious AE or adverse drug reaction (ADR) occurred. These results demonstrate the non-inferiority of DA-5204 compared to DA-9601. DA-5204 is as effective as DA-9601 in the treatment of erosive gastritis. Registered randomized clinical trial at ClinicalTrials.gov (NCT02282670)</P>

Objective : Hemophilia, a genetically determined disorder, is characterized by abnormality of the coagulation mechanism due to functional deficiency of a specific factor, namely VIII or IX. In this study, the effect of Dong-Si acupuncture therapy on the cerebral hemorrhage patient with hemophilia was evaluated. Methods : We treated him with acupuncture by stimulating Dong-Si acupuncture point(Yuk Wan) and assessed the effect by using manual dynamic evaluation of MRC(Medical Research Council) and Modified Barthel Index. Results : After treatment, the bleeding tendency was grossly reduced and bleeding lesion was absorbed gradually. And manual dynamic evaluation of the upper extremity increased from 4 grade to 5 grade. Conclusions : This result suggest that Dong-Si acupuncture therapy on the cerebral hemorrhage patient with hemophilia was effective. And futher studies are required to concretely prove the effectiveness of Dong-Si acupuncture therapy for treating hemorrhagic diseases.

This study was performed to investigate the surface properties of electrochemically oxidized pure titanium by anodic spark deposition technique. Titanium plates of 10×10×1 ㎜ were polished sequentially from # 300 to # 1,000 emery paper. They were ultrasonically washed in ethyl alcohol and acetone for 5 min and dried in a desiccator. Titanium plates and titanium screw implants were anodized in an electrolytic solution that was dissolved calcium and phosphate in water. The electrolytic voltage was set in the range of 190-340 V and the current density was 30 ㎃/㎠. The surface oxide film was characterized by X-ray deffractometer(XRD), scanning electron microscope(SEM) and X-ray photoemission spectroscopy(XPS). The main crystal structure of the titanium oxide was anatase type as analyzed with thin-film X-ray diffractometery. The diameter of micropores increased with increasing the spark forming voltage. The porous coatings showed the growth of cell structure and more compact texture with increasing the spark forming voltage. Microcracks were examined in the coating formed at voltage of 340 V. Ca/P ratio in coatings was increased with increasing the voltage.

Two isoflavonoids were isolated from the flows of Pueraria lobata (Flos puerariae) guided initially fractionation based on brine shrimp lethality assay. The structures were identified as 4',5,7-trihydroxy-6-methoxyisoflavone (tectorigenin) and 4',7-dihydroxy-6-methoxyisoflavone (glycitein), respectively, on the basis of their spectroscopic and physicochemical evidences.

The most widely used nonlinear analog cells are multipliers and dividers. Four-quadrant multipliers have been reported by using variable-transconductance and quarter-square approaches. But they are not reconfigurable to achieve different function such as divider. In this paper, analog four-quadrant multiplier/divider is proposed using operational amplifier and V-Ⅰ converters. The designed multiplier/divider circuits can be reconfigurable in order to perform the different function. The multiplier linear ranges are between -2V and +2V, and nonlinear error is measured 0.87% by SPICE simulation.

Neoplasms of the pineal gland are collectively rare, comprising from 0.4 to 1% of all tntracranial tumors, among them the number of pinealoblastoma is extremely small. A case of pinealoblastoma is reported. A 25-year old female with headache, Parinaud's syndrome and voiding disturbance of 1 month's duration is presented. Neurological findings were the vilateral papilledemas and the bilateral pareses of upward gaze. Vertebral angiography, Conray ventriculography and C-T brain scan revealed a posterior 3rd ventricle tumor. Through the right occipital approach a soft pinkish-grey mass on the pineal region was detected, and biopsy was kone. At the same time ventriculoperitoneal shunt was applied. The pathological finding of the specimen was pinealoblastoma. The patient underwent the radiation therapy with good result.
