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.

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.

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.

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

OBJECTIVE: The aim of this study was to evaluate the reliability of measurements obtained after the superimposition of three-dimensional (3D) digital models by comparing them with those obtained from lateral cephalometric radiographs and photocopies of plaster models for the evaluation of upper molar distalization. METHODS: Data were collected from plaster models and lateral cephalometric radiographs of 20 Class II patients whose maxillary first molars were distalized with an intraoral distalizer. The posterior movements of the maxillary first molars were evaluated using lateral cephalometric radiographs (group CP), photocopies of plaster models (group PH), and digitized 3D models (group TD). Additionally, distalization and expansion of the other teeth and the degrees of molar rotation were measured in group PH and group TD and compared between the two groups. RESULTS: No significant difference was observed regarding the amount of molar distalization among the three groups. A comparison of the aforementioned parameters between group PH and group TD did not reveal any significant difference. CONCLUSIONS: 3D digital models are reliable to assess the results of upper molar distalization and can be considered a valid alternative to conventional measurement methods.
