BACKGROUND: Various kinds of methods had been tried to reduce pain on injection of propofol. In this study, the effect of lidocaine pretreatment and that of temperature controlled injections were compared and evaluated its clinical utility. METHODS: One hundred and twenty patients were randomly allocated into 4 groups after permission. Room temperature propofol was used as induction agent in group P,. In group C, cooling (4 degrees C) propofol was used and warming propofol (37 degrees C) in group H. And room temperature propofol following lidocaine (1 mg/kg) was used in group L. Injection dosage of propofol was 2 mg/kg and injection speed was 2 ml/sec in all groups. In each patients, pain score and visual analog scale were measured and tested by ANOVA or Kruskal-Wallis test. RESULTS: There were no statistical significant difference in pain score among the 4 groups. But in visual analog scale analysis, group L markedly reduced values than the other groups by statistically significant manner (in Duncan grouping). CONCLUSION: The alleviating effect of lidocaine pretreatment on painful injection was better than that of changing temperature of propofol itself. More over effectiveness, in view of simplicity, we recommend lidocaine pretreatment.

BACKGROUND: The obese patients increased recently in Korea due to excessive energy intake and decreased physical activity. We are well known that obesity is associted with an increased risk of cardiovascular disease, angina pectoris, hypertension, but not known to influence of weight gain to change in cardio-vascular risk factors. Once, the study of obesity are many but the study of influence of weight gain are small in Korea. This study investigated to influence of weight gain in cardio-vascular risk factors. METHODS: We gatherd case and control group among persons who has taken twice medical examination except disease person from October 1990 to October 1995 at SungAe General hospital. In our study, total 167 case, compare weight gain group(>3kg) with control group to change in cardiovascular risk factor. RESULTS: Sex, age, smoking history, obesity index were not statistically significant difference between two group in the first medical examination. systolic blood pressure, diastolic blood pressure, fasting blood sugar, HDL, total cholesterol/HDL were not statistically significant difference between two group for weight gain. Total cholesterol and triglyceride, LDL were stastistically significant increased. CONCLUSIONS: Weight gain was increased of total cholestrol and triglyceride, LDL, so weight control was important.

PURPOSE: To evaluate the interval between, and the total number of, applications of photodynamic therapy in-patients with subfoveal choroidal neovascularization caused by various etiologies. METHODS: Ninety-five patients (108 eyes) received photodynamic therapy. At follow-up examination every 6 weeks, retreatment with the same regimen was applied if angiography showed definite fluorescein leakage. We retrospectively evaluated the interval between treatments and their total number in the group of patients who were able to be followed up for more than 6 months. RESULTS: The average number of applications of verteporfin treatment was 2.46 over a mean follow-up of 14.93 months. The average interval between treatments was 3.65 months. CONCLUSIONS: Further evaluation is needed to analyze the results of photodynamic therapy in Koreans and thereby produce a set of more accurate guidelines.

The treatment of supracondylar fracture of the femur remains a difficult problem because of the wide range of portential complications. In the past, authors thought conservative treatment was superior to operative treatment of supracondylar fracture of the femur. In addition, the advent of the Cast-Brace introduced the change in concept of the conservative treatment. Recently, however, the advances in the techniques and in the devices used in intemal fixation have encouraged the operative treatment. Tibiofemoral angle, gap or stepping of the articular surface of the distal femur, range of motion of the knee, and pains in the knee were used to evaluate the following results investigated by statistical study(T-test). These clinical results were shown by analyzing 49 cases of supracondylar fracture of the femur trea ted in the Department of Orthopedic Surgery, Hallym College of Medicine, from Jan. 1980 to Dec. 1983 1. We end result of each patient was evaluated by scaled score value calculated from above mentioned criteria. 2. The mean value of the operative treatment(35 cases) was 31.03±5.52, while that of the conservative treatment(14 cases) was 27.71±4.56. 3. The mean value of the group which began the exercise of the knee joint within 2 weeks (33 cases) was 32.24±4.43. The mean value of the other group which began the exercise of the knee joint after 2 weeks(16 cases) was 25.78±4.56. This difference of means between two groups was statistically significant. Beginning the knee joint exercise within 2 weeks has large effect on the result of the treatment. 4.The results of treatment in patient over age of 50 were graded as fair irrespective of methods of treatment. 5. Various devices were used in intemal fixation but there was no difference in the results. 6. We mean value of the Tibiofemoral angle(difference from normal angle) in the operative treatment was 2.37±6.25 and that of the conservative treatment was 8.04±4.62. Both of the above method of treatment showed a varus trend, especially in the conservative treatment. In statistical study, through, there was no significance in two methods.

The purpose of this study was to compare the microleakage of the IPS Empress ceramic crown according to 1) margin types such as rounded shoulder and bevel, 2) margin locations such as enamel and dentine, 3) resin cement types such as Variolink and Bistite. For this study, 80 extracted premolar teeth were used. After 10 experimental dies were prepared for each group, the IPS Empress ceramic crowns were fabricated on the dies and cemented with one of two types of resin cement. After 1,000 cycles of thermal changes were given with the thermocycling unit, each specimen was sectioned with a low speed diamond saw in both the buccolingual and the mesiodistal direction. The microleakage was then measured with a stereo microscope. The obtained results were as follows : 1. Every experimental group showed microleakage. The microleakage of the crowns which had a rounded shoulder on enamel cemented with Variolink was the lowest of all. The resulting rank of the mean microleakage was rounded shoulder on enamel using Variolink(0.601mm), rounded shoulder on enamel using Bistite (0.794mm), bevel on enamel using Variolink (0.826mm), rounded shoulder on dentine using Variolink(1.054mm), bevel on enamel using Bistite(1.087mm), rounded shoulder on dentine using Bistite(1.176mm), bevel on dentine using Variolink(1.258mm), and bevel on dentine using Bistite(1.467mm). 2. The statistically significant differences in the microleakage were found in 4 cases: rounded shoulder on enamel using Variolink and bevel on dentine using Variolink, rounded shoulder on enamel using Variolink and bevel on dentine using Bistite, rounded shoulder on enamel using Bistite and bevel on dentine using Bistite, bevel on enamel using Variolink and bevel on dentine using Bistite. 3. The microleakage of rounded shoulder finish line was lower than that of bevel finish line. The statistically significant differences were found with respect to the type of finish lines. 4. The microleakage of the finish line on enamel was lower than that of finish line on dentine. The statistically significant differences were found with respect to the location of the finish lines. 5. The microleakage of the Variolink cement was lower than that of the Bistite cement. The statistically significant differences were found with respect to the resin cements.
