4.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.

5.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.

7.Dustfalls and Various Ion Concentrations in Their Filtrates in an Urban and in a Rural Districts.
Korean Journal of Preventive Medicine 1985;18(1):59-72
During a period from February 1st to November 30th in 1983, measurements were made twice a month on dustfalls and concentrations of various cations and anions in their filtrates in an urban (Heuksuk-dong, Seoul) and in a rural (Ansung) districts. Standard British Deposit Gauge method was applied for collection of dustfalls and ion chromatographic method using Ion Chromatograph 10 (Dionex, U.S.A.) for determination of cation and anion concentrations. The results obtained were as follows: 1. Annual mean values of dustfalls were 8.30+/-5.09 tons/km2/month in an urban and 6.20+/-0.82 tons/km2/month in a rural districts. And annual mean values of pH of filtrates of the collected samples were 5.3+/-0.76 in an urban and 6.0+/-0.82 in a rural districts. 2. Annual mean concentrations of common cations and anions in their filtrates were as follows: Some of anions such as Br-, PO4-3 and NO2 were scarcely detected and F was measured at very low concentrations ranging from 0.1 to 0.5 ppm in Feb., Oct. and Nov. in an urban and in Feb. in a rural districts. 3. By two-way analysis of variance with 4 replications for dustfalls, pH and concentrations of various ion by district and month of a year, statistically significant differences were noted in dustfalls (p<0.01), pH (p<0.01) and concentrations of various ion (p<0.01) by month of a year, and in dustfalls (p<0.05) and concentrations of various ion such as NH4, Ca, NO3 and SO4 (p<0.01) by district. 4. There were statistically significant differences pH in Spring (Feb., Mar. and Apr.) (p<0.01) and in SO4 in Autumn (Aug., Sept., Oct. and Nov.) (p<0.05) between the two districts.

8.Influence of some factors on the optimal pH of ribonuclease from Cobra snake venom
Journal of Medicinal Materials - Hanoi 2005;10(5):153-158
Evaluate the influences of some factors as enzyme level, the time of diluting enzyme solution, substrate level and temperature on pH value of RNase from Vietnam Cobra (Naja naja) venom. Results: the changes of pH value for cobra venom RNase can be depended on concentrations of the enzyme and substrate. This variation in the pH value of the enzyme can be explained by existence of this RNase as an enzyme system composed of some interconvertible forms. The interconversion between these enzyme forms is very slow process (counting by hours) in comparison with the rate of reactions

The purpose of this study is to observe and compare the dynamic change of artificially demineralized enamel by remineralization solutions of different degrees of saturation at pH 4.3. In this study, 30 enamel specimens were demineralized artificially by lactic acid buffered solution. Each of 10 specimens was immersed in pH 4.3 remineralization solution of three different degrees of saturation (0.22, 0.30, 0.35) for 10 days. After demineralization and remineralization, images were taken by a polarizing microscope (x 100). The density of lesion were determined from images taken after demineralization and remineralization. During remineralization process, mineral deposition and mineral loss occurred at the same time. After remineralization, total mineral amount and width of surface lesion increased in all groups. The higher degree of saturation was, the more mineral deposition occurred in surface lesion and the amount of mineral deposition was not much in subsurface lesion. Total demineralized depth increased in all groups.
