For the isolation of mycobacteria in sputum specimens, it is essential to use the most gentle procedure of digestion system for the survival of organisms. The present studies were undertaken to evaluate and compare the effect of various sputum digestants on the death of Mycobacterium fortuitum and Mycobacterium tuberculosis. The results were summarized as follows: 1. Death rates of M. tuberculosis in a solution of 2% NaOH, 3% NaOH and 4% NaOH digestants after 30 minutes of contact time were 97.1%, 97.6% and 97.9%, respectively. In the digestants of 2% NaOH, 3% NaOH and 4% NaOH solution after 1 hour of contact time, survival rates were less than 2%. 2. Death rates of M. tuberculosis in Zephiran-N-acetyl-L-cysteine digestant after 30 and 60 minutes of contact time were 28.5% and 39.5%, while those of M. fortuitum after the contact time were 74.1% and 81.2%, respectively. 3. Death rates of M. tuberculosis in Zephiran-trisodium phosphate digestant after 30 and 60 minutes of contact time were 36.1% and 40.3%, and those of M. fortuitum after the contact time were 71.6% and 74.2%, respectively. 4. Death rates of M. tuberculosis and M. fortuitum in N-acetyl-L-cysteine-NaOH (2%) digestant were similar to the digestant of 2% NaOH solution.

The paper describes the development of a new automatic wrapping machine using paper films as it has not been used so far. The most of the automatic wrapping machine have used the vinyl film causing environmental pollution, the paper films, however, have a weak point in the aspect of high temperature adhesion. Therefore, the mechanism of the existing wrapping machine should be altered to prevent it from curling effect through the technical know-how. A new method and technology reducing the curling effect in the automnatic wrapping machine are demonstrated by using developed blower. Thus it is exqection and will decrease environmental pollution.

본 연구에서는 치수강이 개방된 근관와동에 5.25% NaOCl용액을 각각 다른 시간 동안 적용시킨 뒤 접착레진에 의한 미세인장결합강도의 변화를 측정하였으며, 10% sodium ascorbate를 NaOCl 용액에 일정시간 노출시킨 상아질에 다시 10분 동안 적용하여 결합강도에 미치는 효과를 연구하고자 하였다. 연구결과 본 실험에서 상부 치수강 상아질과 하부 치수강 상아질에 대한 결합강도는 모든 실험군내에서 유의한 차이 (p > 0.05)를 보이지 않았다. 5.25% NaOCl 용액을 적용하지 않고 치수강 상아질에 접착시킨 대조군에 비해 20분간 적용시킨 실험군에서는 결합강도의 감소가 초래되었으나 통계적인 유의성 (p > 0.05)은 없었다. 그러나 5.25% NaOCl 용액을 40분과 80분 동안 치수강 상아질에 적용시킨 실험군에서는 대조군에 비해 유의하게 낮은(p < 0.05) 결합강도의 변화를 나타내었다. 5.25% NaOCl 용액을 40분동안 그리고 10% sodium ascorbate를 10분간 처리한 실험군에서는 유의한 결합강도의 회복을 나타내었다. 그러나 5.25% NaOCl 용액을 80분 동안 그리고 10% sodium ascorbate를 10분간 적용한 실험군에서는 대조군에 비해 통계적으로 유의한 차이(p < 0.05)를 보임으로써 여전히 결합강도가 회복되지 못하고 있음을 나타내었다. 5.25% NaOCl 용액을 5분간 적용한 뒤 10% sodium ascorbate를 10분간 적용한 실험군에서는 오히려 대조군에 비해 높은 결합강도(p < 0.05)를 보여줌으로써 높은 회복효과를 나타내었다. Clinical suggestion for the limitation of application time of NaOCl solution is needed to avoid large reductions in resin-dentin bond strength. The aim of this study was to measure the change of -tensile bond strength after the various application time of 5.25% NaOCl solution to pulp chamber dentin in endodontic access cavity, and to evaluate the effect of 10% sodium ascorbate application for 10 min on bond strength after the treatment of 5.25% NaOCl solution. In this experiment, there were no statistical differences(p > 0.05) in bond strengths between upper chamber dentin and lower chamber dentin. NaOCl-treated group for 20 min did not show any significant decrease(p > 0.05) in bond strength than non-treated control group. In contrast to that, bond strengths of NaOCl-treated groups for 40 & 80 min were significantly lower(p < 0.05) than that of non-treated control group. 10% sodium ascorbate retreated group for 10 min after 5.25% NaOCl application for 40 min to chamber dentin showed the recovery of bond strength significantly. However, the bond strength of sodium ascorbate retreated group after 5.25% NaOCl application for 80 min was still significantly lower(p < 0.05) compared to the non-treated control group, which means the reductions in resin-dentin bond strength were not fully reversed. On the contrary, sodium ascorbate retreated group after 5.25% NaOCl application for 5 min showed significantly higher(p < 0.05) bond strength compared to the control group, which demonstrates its superior recovery effect. In SEM exminations of specimens retreated with 10% sodium ascorbate after NaOCl application for 40 & 80 min showed that resin tags were formed clearly and densely, but weakly in density and homogeneity of individual resin tag compared to the control specimen.

The purpose of this study was to investigate the effects of glucose, sucrose, and glucose polymer(GP) ingestion on the carbohydrate and lipid metabolism during treadmill running in rats. Rats were randomly assigned to normal, control and carbohydrate groups. Carbohydrate group was divided into glucose, sucrose and GP ingested rats. The experiment was carried out after overnight fasting. Rats were administrated either normal saline(control) or carbohydrates solutions of formulated glucose(6%), sucrose(6%) and GP(6%) via polyethlene tube to stomach before treadmill run. Exercise was loaded by a treadmill run at the speed of 1 km/hour for 30, 60 and 120 minutes. The results of experiment were as follows: Plasma glucose levels were decreased in proportion to the exercise time in control, but increased at treadmill run 30 minutes and then gradually decreased with the lapse of the exercise time in carbohydrates compared with normal rats. It decreased in control, glucose, sucrose and GP compared with normal rats in decreasing order at treadmill run 120 minutes(% change of plasma glucose level of control, glucose, sucrose and GP compared with normal rats were 67, 74, 87 and 91 in plasma glucose level at treadmill run 120 min., respectively). Plasma lactate levels were increased by the exercise loading compared with normal in control and carbohydrates ingested rats. It increased in control, sucrose and GP in increasing order compared with normal rats, at treadmill run 120 minutes(% change of plasma lactate level of control, glucose, sucrose and GP compared with normal rats were 167, 185, 149 and 114 in plasma lactate level at treadmill run 120 min., respectively). Plasma FFA levels had tendency to increase by the exercise loading compared with normal in control and carbohydrates ingested rats. It showed increase in the sucrose, glucose, GP and control rats in Increasing order compared with normal rats at treadmill run 120 minutes(% change of plasma FFA level of control, glucose, sucrose and GP compared with normal rats were 151, 153, 166 and 152 in plasma FFA level at treadmill run 120 min., respectively). Plasma acetoacetate levels were higher in control compared with carbohydrates ingested rats at treadmill run 30, 60 and 120 minutes. Plasma beta-hydroxybutyrate levels increased by exercise compared with normal rats in control and carbohydrates ingested rats at treadmill run 30, 60, 120 minutes. Plasma insulin levels were decreased in proportion to the exercise time in control compared with normal rats, but in carbohydrates ingested rats increased at treadmill run 30 minutes and then gradually deceased with the lapse of the exercise time compared with normal. In carbohydrates ingested rats, plasma insulin levies were higher than control. Hematocrit did not show any difference between control and carbohydrates rats at treadmill run 30, 60 and 120 minutes. From these experimental results, it is suggested that the exhaustion of skeletal muscle glycogen, the hypoglycemia, the overproduction of lactate and dehydration is delayed in carbohydrates ingested rats. GP of the carbohydrates is considered as the most effective for these effects. Therefore, intake of carbohydrates before exercise, especially GP seems to increase performance in the prolonged moderate exercise.
