We have examined the comparative efficacy of small doses of intravenous urapidil and labetalol in blunting hemodynamic response to endotracheal intubation and surgical incision in 30 patients without cardiovascular diseases. After intravenous urapidil 0.2 mg/kg or labetalol 0.2 mg/kg anesthesia was induced with thiopental 5mg/kg. Endotracheal intubation was facilitated by vecuronium 0.15 mg/kg with priming principle and anesthesia was maintained with enflurane and nitrous oxide in oxygen. Systolic, diastolic and mean arterial pressure and heart rate were measured before administration of the drugs, 5 minute after administration, just prior to endotracheal intubation and 1, 3, 5, 10 minute after intubatin. Also the peak blood pressures and heart rate within 10 minutes after surgical incision were measured. Endotracheal intubation and surgical stimulation were associated with significant increases in blood pressures and heart rate in both urapidil and labetalol group. Comparison of the changes in systolic, diastolic, and mean artrial pressures and heart rate between urapidil and labetalol group showed no significant difference except peak systolic pressure after surgical incision. It is concluded that the pressor response to endotracheal intubation and surgical stimulation are not influenced significantly by urapidil 0.2 mg/kg or labetalol 0.2 mg/kg. However, urapidil and labetalol preloading may be similarly effective in the blunting of the increases in blood pressures with larger doses of the durgs during anesthetic induction.

To evaluate the specificity and historical trends of the anesthesia in Chungnam National University Hospital, anesthetic experiences of 83,572 in total performed at Chungnam National University Hospital from January 1967 to December 1996 were analyzed statistically and clinically according to age, sex, surgical department, physical status, elective and emergency surgery, premedicants, IV anesthetics, anesthetic methods, inhalational anesthetics, muscle relaxants. The results were as follows : 1. The number of cases has been steadily increased year by year. 2. The ratio of male to female was 52.8% : 47.2%. 3. According to the age, There were 44,905 cases (54%) in the group of 13-45 years. 4. According to the ASA classification of physical status, most of the cases were belonged to the class 1 & 2 (72.5%). 5. The ratio of elective to emergency was 79.4% to 20.6%. 6. Recently, glycopyrrolate has been used increasingly. 7. Thiopental sodium has been mainly used for intravenous induction agent. 8. General anesthesia has been used mainly. 9. Enflurane is the most common inhalational anesthetic agent. but Isoflurane has been used increasingly. 10. Most of muscle relaxants are Pancuronium & Vecuronium(84.5%).

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.
Chemical Reaction of Glazed Refractory with Al-deoxidized Molten Steel

<P>A high alumina refractory, glazed by typical ladle slag of CaO–MgO–Al<SUB>2</SUB>O<SUB>3</SUB>–SiO<SUB>2</SUB> was investigated to understand the influence of the glazed refractory on the generation of non-metallic inclusions in Al-deoxidized molten steel at 1600°C. The variations of microstructure and chemistry of the glazed refractory with reaction time were studied. Thermodynamic analysis was simultaneously carried out to understand the complex chemical reactions. During the reaction between the glazed refractory and molten steel, two chemical reactions were observed: between glaze and molten steel, and between glaze and original refractory. By the chemical reactions, SiO<SUB>2</SUB> in the glaze was reduced to [Si] by [Al] in molten steel. The glaze layer also gradually changed from the liquid CaO–MgO–Al<SUB>2</SUB>O<SUB>3</SUB>–SiO<SUB>2</SUB> phase with small amount of embedded spinel particles to the liquid CaO–MgO–Al<SUB>2</SUB>O<SUB>3</SUB> phase with embedded spinel and CaAl<SUB>4</SUB>O<SUB>7</SUB> particles. Severe erosion was observed in the porous spinel area of a refractory. Spinel inclusions were found as major inclusions originated from the glazed refractory. The erosion mechanism of the glazed refractory was proposed in the present study.</P>
