During general anesthesia, removal of exhaled carbon dioxide by rebreathing appliances is provided by chemical absorption and this carbon dioxide absorption during anesthesia would at first glance seem to be a simple problem. The problem, however, is far more complicated and much attention must be given to details of rebreathing appliances. Incomplete removal of carbon dioxide in circle absorber systems, which are commonly used today must be carefully monitored to prevent hypercapnea caused by accumulation of carbon dioxide in the breathing circuits. Although circle absorbers have been developed through clinical trials anesthesiologists have no reliable indication of the end point of useful life of the absorbent. This study was undertaken to investigate the useful life of the soda lime used in two type of canisters (type A: canister of anesthesia machine. Quantiflex, USA. 12.9cmX16.6cm, tbye B: canister of anesthesia machine, International 2. U.K., 13.1cmX16.9cm). the effect of flow rate on this useful life and the relations between indicator change and the endpoint of useful life of the soda lime. The control group used a as total flow rate of fresh gases at 2.0 liters per minute and the experimental group used a total flow rate of 4.0 liters per minute. The carbon dioxide concentration of 0.1% at the canister exit was employed as the end point of useful life of the absorbent and the exit carbon dioxide concentration were monitored continuously by intra-red carbon dioxide monitor apparatus(Datex Normocap CD-102, Pinland). Also the carbon dioxide concentration in the respiratory circuit of exhaling side was examined. The results were as follows: 1) In type A, the average useful life of soda lime was 1,885 minutes in the control group and 2,514 minutes in the experimental group. In type B, the average useful life of soda lime was 1,587 minutes in the control group and 1,980 minutes in the experimental group. 2) At the end point of useful life of the absorbent the level of the color change of the indicator of the absorbent in all types was above the three-fourth height of two chambered canister. 3) At the end point, end tidal CO2 concentration was 3.5 vol% in the control group 2.88 vol% in the experimental group. The data obtained from this observation indicated that the increase of total flow rate of gas and the type A canister prolonged the useful life of soda lime and that the double chambered canister could be used safely until the color change of the indicator reached the level of three fourth the height of the canister.

To investigate whether anti-Candida proteinase antibody could be a diagnostic marker, we examined seroreactivity to proteinase in sera from 90 healthy controls and 8 of C. albicans culture-positive patients. Previously we purified proteinases of C. albicans, C. tropicalis, and C. parapsilosis using a series of chromatographic steps consisting of DEAE- Sepharose, Sephacryl S-200, and size-exclusion HPLC. ELISA and Western blot technique were adopted to examine seroreactivity of C. albicans proteinase with sera. On ELISA, the seroreactivities of healthy controls and C. albicans-cultured patients were 0.601 +- 0.014 (mean+SEM), and 0.695 +- 0.079, respectively (P=0.084, t-test). In C. albicans-cultured patients, the positive rate was 62.5% (5/8) and the positive rate of healthy controls was 39% (35/90). On Western blot analysis, C. albicans proteinase molecule was blotted by all sera tested. But the intensity of blotted band was different with the same dilution of sera; the intensity of C. albicans proteinase molecule band blotted by 2 sera of 3 healthy control's sera was distinctively lower than that by C. albicans-cultured patients sera. However, all sera including C. albicans-cultured patient's sera did not blot the proteinase secreted by C. tropicalis and C. parapsilosis. It is necessary to collect sequential sera of patients with candidiasis and to establish a cut-off value for ELISA or serum dilution for Western blot analysis that will give reliable test sensitivity and specificity.

Nonparasitic liver cysts are usually asymptomatic and require treatment when they are symptomatic. Hence, many treatment methods, such as percutaneous aspiration, aspiration followed by injection of sclerosing agents into the cyst, excision of the liver cyst, and hepatic resection have been suggested. Recently, the laparoscopic cholecystectomy has become popular, and this method has been challenged as a treatment for symptomatic nonparasitic liver cysts. To evaluate the feasibility of using and the disadvantages of laparoscopic treatment, we reviewed the medical records of 10 patients with a symptomatic nonparasitic liver cyst who were treated by laparoscopic unroofing at the Department of Surgery, Chungbuk National University Hospital. All patients were diagnosed by USG and abdominal CT. All patients had vague abominal discomfort, abdominal distension, or indigestion. The sizes of the liver cysts varied from 7 cm to 20 cm, and half of them were located in the right lobe, the other half in the left lobe. In 5 patients, the cysts were multiple. The mean operative time was 99.5 minutes, and mean hospital stay was 8 days. The follow up period was from 3 to 37 months. Two patients required a reoperation because of cyst infection and a rapidly growing cyst. Remaining cysts were identified in 4 among 8 patients, but they did not have any symptoms. In conclusion, laparoscopic unroofing is feasible as a first choice for treatment of a symptomatic liver cyst. However, in liver cyst that are located at the dome of right side or in a thickened wall, incomplete unroofing and residual cysts can be anticipated. In this case, we suggest that open cyst excision or unroofing may be better than laparoscopic unroofing.

PURPOSE: Prealbumin is known as a biochemical marker for assessing nutritional status, and it is influenced by a systemic inflammatory condition. This study aims to find any correlation between patients' low serum prealbumin in electrical burn and unhealed burn surface area and insufficient nutritional support. METHODS: Data were collected by a review of the medical charts of patients admitted to Hanil General Hospital for electrical burn. Laboratory results such as prealbumin, albumin, total lymphocyte count (TLC), and C-reactive protein (CRP) were collected and tested every week. Residual burn surface area (residual BSA) during a specific period was calculated from the surgery record. Statistical analysis was conducted using Pearson's correlation and multiple regression analysis. RESULTS: A total of 30 subjects were selected, all male. Average total burn surface area was 20.9±14.9%, and patients were operated on about three times after admission. There was statistical significance among all variables in Pearson's correlation test, but in multiple regression analysis, albumin and CRP were significant compared with prealbumin. CONCLUSION: The results could indicate that burn causes a systemic inflammatory reaction, which could affect the serum prealbumin level. Further study concerning the biological plausibility of each variable is needed.

Polyporoid and corticioid fungi are among the most important wood-decay fungi. Not only do they contribute to nutrient cycling by decomposing wood debris, but they are also valuable sources for natural products. Polyporoid and corticioid wood-inhabiting fungi were investigated in Odaesan National Park. Fruit bodies were collected and identified based on morphological and molecular analyses using 28S and internal transcribed spacer regions of DNA sequences. As a result, a total of 149 species, 69 genera, 22 families, and 11 orders were recognized. Half (74 species) of the species were polypores, and the other half (75 species) were corticioid fungi. Most of the species belonged to Polyporales (92 species) followed by Hymenochaetales (33 species) and Russulales (11 species). At the genus level, a high number of species was observed from Steccherinum, Hyphodontia, Phanerochaete, Postia, and Trametes. Concerning distribution, almost all the species could be found below 1,000 m, and only 20% of the species were observed from above 1,000 m. Stereum subtomentosum, Trametes versicolor, T. hirsuta, T. pubescens, Bjerkandera adusta, and Ganoderma applanatum had wide distribution areas. Deciduous wood was the preferred substrate for the collected species. Sixty-three species were new to this region, and 21 species were new to Korea, of which 17 species were described and illustrated.

Gastric tuberculosis is a rare disease. It usually occurs secondarily to another lesions and mainly in the lungs. Only a few cases of primary gastric tuberculosis have been reported in the literature. Most commonly, gastric tuberculosis lesion locates in the lesser curvature side of the antrum. Therefore the clinical picture is similar to the peptic ulcer. A 24-year-old women visited to the Inha university hospital complaining of vomiting and epigastric discomfort. Gastrofiberscopy showed multiple polypoid mass around the pylorus with stenotic pyloric channel. Subtotal gastrectomy was performed and histologic examination revealed chronic granulomatous inflammation with caseation necrosis. That is compatible with tuberculosis. The patient was taken antituberculosis medication without complication. So we report the case of pyloric obstruction due to gastric tuberculosis with review of the literature.
