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.

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.

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

The principal objective of this study was to evaluate the quality characteristics of mungbeanmook prepared with five different levels (0, 5, 10, 15, and 20%) of Gugija (Lycii fructus) infusion. We analyzed Hunter's color values, pH, texture characteristics, and perfomed sensory evaluation of mungbeanmook prepared with Gugija infusion. The pH levels of mungbeanmook ranged between 5.45 and 6.12 and did not show significant differences. As Gugija infusion concentration increased, the color lightness "L" value decreased, whereas redness color "a" value and yellowness color "b" values increased (P<0.05). With regard to mechanical texture properties of the mungbeanmook samples, as the Gugija infusion concentration increased, the scores of hardness, chewiness, and gumminess all significantly decreased (P<0.05) whereas there were no significant differences in springiness or cohesiveness. The results of the sensory evaluation showed that the score of the LFLT10 sample (10% Gugija infusion) was significantly higher than those of others in terms of taste, color, flavor, texture, and overall quality (P<0.05). Taken together, the recommended optimum level of Gugija infusion in mungbeanmook is 10% for sensory evaluation. Gugija infusion can be a useful approach to improving quality of mungbeenmook as a functional food.

BACKGROUND: Insufficient sample volume can cause unnecessary blood loss and inaccurate arterial blood gas and electrolytes testing. The aim of this study was to determine the adequate sample volume, that is required for accurate arterial blood gas and electrolyte testing from arterial catheters. METHODS: Patients had four different arterial blood samples (0.2 ml, 0.4 ml, 0.6 ml and 1 ml [control], respectively) taken sequentially in random order. Samples were analyzed for pH, PaCO2, PaO2, hematocrit, Na+, K+, Ca2+ and Mg2+ using NOVA blood gas analyzer. RESULTS: A total of 27 patients were recruited for the study. All sample volumes tested provided the results of pH, PaCO2, PaO2 and hematocrit that were statistically similar to control values. However, the results of electrolytes (K+, Ca2+ and Mg2+) in all sample volumes tested were significantly lower than the control values and an increasing sample volume equated to blood results trending closer to those obtained with the control sample. CONCLUSIONS: This study showed that there is not one sample volume that will provide accurate results for all blood components. The study tested a variety of sample volumes and found that although even small sample volume of 0.2 ml provided accurate results for pH, PaCO2, PaO2 and hematocrit. No sample volume that was tested provided accurate results for K+, Ca2+ and Mg2+.
