This study evaluated the efficacy of an office bleaching gel (RemeWhite, Remedent Inc., Deurle, Belgium) containing 30% hydrogen peroxide. 31 volunteers were recieved office bleaching with the RemeWhite for 3 times at one visit, total 2 visits. As control group, the same gel in which hydrogen peroxide was not included was applied to 31 volunteers with the same protocol. The shade change (DeltaE*, color difference) of 12 anterior teeth was measured using Colorimerter and Vitapan classical shade guide. The shade change of overall teeth in the experimental group was significantly greater than that in the control group which was measured using Colorimeter. There was also a significant difference between baseline and 14 weeks or 26 weeks though color rebounding phenomenon occurred as time went by. Small shade change difference can be measured accurately using Colorimeter than using Vitapan classical shade guide.

This study evaluated the safety of an office bleaching gel (RemeWhite, Remedent Inc., Deurle, Belgium) containing 30% hydrogen peroxide. 37 volunteers were recieved office bleaching with the RemeWhite for 3 times at one visit, total 2 visits. As control group, the same gel in which hydrogen peroxide was not included was applied to 34 volunteers with the same protocol. There was no difference between experimental group and control group using electric pulp test. In the result of gingival inflammation index and tooth sensitivity test, there was mild pain response in experimental group but it disappeared as time went by. Therefore, safety of the office bleaching gel containing 30% hydrogen peroxide was confirmed.

5.A Case Report of Postmortem Identification Through Medical Information of Bravo(TM) Capsule in the Esophagus.
Korean Journal of Legal Medicine 2006;30(1):76-78
Forensic pathologists must determine not only the cause and manner of death, but also the identity of the deceased. Some surgical procedures or implants may have a great value for identification. A case of quickly solved postmortem identification through medical information of an ambulatory pH monitoring capsule (Bravo(TM) Capsule) in the esophagus is reported.

To evaluate the cerebral blood flow in feline hydrocephalic brain, this study was designed to measure the regional cerebral blood flow(rCBF;frontal and periventricular area) by the hydrogen clearance method in different stages of the kaolin-induced hydrocephalus and the postshunt status. The results were as follows: 1) A reduction of rCBF was detected in the left periventricular area at two weeks after kaolin injection. A significant reduction of rCBF was revealed in the left periventricular area at two and four weeks after kaolin injection. However, the rCBF of the left frontal cortex was significantly decreased at four weks after kaolin injection. 2) At one week after shunt operation, the significant restroration of rCBF was found in the left frontal cortex and the left periventricular area.

10.Some alterations of hematology and coagulation in burn patients
Journal of Vietnamese Medicine 1998;231(12):49-52
The authors studied on alterations of hematology and coagulation of 2 patient groups, supernatal and deep burn, along 20 first days of intensive treatment. The results showed that decreased platelet aggregation, prolonged bleeding time, reduced prothrombine rate and reduced fibrinogen level in deep burn group, compared to supernatal burn group. These differences were seen mainly at time of T1 and occasional at time T2 and T3.
