The purpose of this study was to compare the fitness of the IPS Empress ceramic crowns according to margin type such as bevel, shoulder, rounded shoulder, shoulder with bevel, rounded shoulder with bevel and grooved bevel. After 10 experimental dies were constructed for each group, the IPS Empress ceramic crowns were fabricated on the dies, cemented with resin cement(Bistite resin cement, Tokuyama Soda Co. Ltd., Japan) and embeded in clear epoxy resin. Each specimen was sectioned with a low speed diamond saw in both the faciopalatal and the mesiodistal direction. The cement film thickness was measured with a measuring microscope. The obtained results were as follows : 1. The fitness at the external margin was good in the following order: rounded shoulder(28.99), shoulder with bevel(31.33), grooved bevel(31.79), rounded shoulder with bevel(34.65), bevel(35.02) and shoulder(35.08). However there is no significant statistical difference. 2. The fitness at the internal margin of bevel(25.75), rounded shoulder(31.24), shoulder with bevel(32.07) and rounded shoulder with bevel(34.45) was better than that of shoulder(47.98). 3. The fitness at the axial surface of bevel(26.58) was better than that of shoulder(49.59). 4. The fitness at the central fossa was good in the following order: shoulder with bevel(38.88), grooved bevel(40.46) rounded shoulder with shoulder(46.29), shoulder(48.91), bevel(49.47) and rounded bevel(52.07). However there is no significant statistical difference. 5. Overall fitness of bevel(29.71), rounded shoulder(32.49) and shoulder with bevel(34.47) was better than that of shoulder(44.73).

The purpose of this study was to define the optimum dose of lidocaine required to reduced pain on injection of diazepam. We conducted a prospective, randomized trial on l20 patients undergoing anesthesia. patients were allocated to four groups according to the lidocaine do sage: group A(control), no lidocaine; group B, lidocaine 0.1 mg/kg; group C, lidocaine 0.2 mg/kg; group D, lidocaine 0.4 mg/kg. our results sbowed that a dose of lidocaine 0.4 mg/kg significa ntly reduced the incidence of pain.

BACKGROUND: The mechanically ventilated patient's stay in the emergency department (ED) is brief but ventilatory management and intervention must be optimal. Agitation, anxiety, distress, and discomfort are common complications far the ventilated patient. So, sedation is necessary to reduce these complications. METHODS: Patients were monitored and mechanically ventilated. Midazolam was intravenously administered as loading dose(3-5mg), followed by continuous infusion at a rate of 0.06mg/kg/hr, titrated to achieve a predetermined sedation level (Ramsay's sedation score: 2-5 points, Glasgow coma score scathe : 8-11 points). RESULTS: After onset of predetermined sedation, systolic and diastolic blood pressure and heart rate remained stable during continuous infusion when compared with those of the initial state. Arterial blood gas and peak inspiratory pressure remained unchanged but respiratory rate was decreased to allowable ranges. CONCLUSION: A short-term continuous infusion of midazolam was a safe and erective method for sedation of ventilated patients in ED.

BACKGROUND: The red cell distribution width(RDW) has been reported to be of value in discriminating iron deficiency anemia(IDA) from the anemia of the other causes(non-IDA). The combination of a low MCV and a high RDW may indicate iron deficiency anemia. The purpose of this study was to discriminate IDA from anemia, using automated blood cell count alone. METHODS: We collected 139 cases of anemia in outpatients, with 80 cases of IDA and 59 cases of anemia due to other causes, from July 1995 to September 1996 in department of family medicine, Pusan Paik hospital. RESULTS: The sex distribution was 39(28.1%) in male, 100(71.9%) in female. The age distribution was 15 to 79 year. The hemoglobin level and MCV in IDA(9.5+/-1.6g/dl, 77.5+/-8.9fl) was significantly lower than those in non-IDA(10.1+/-1.5g/dl, 87.6+/-10.5fl)(P=0.042, P<0.001, respectively). And mean RDW in IDA(16.9+/-3.3%) was significantly higher than that in non-IDA(15.1+/-3.2%)(P<0.001). In discriminating IDA from anemia, we drew receiver operating characteristic curves (ROC curves) with each value of MCV and RDW. The cut-off value of MCV was 83fl, and in that value, the sensitivity and specificity were 75.9% and 72.9%, respectively. The cut-off value of RDW was 14.3%, and the sensitivity and specificity were 78.2% and 57.6 %, respectively. We combined each value of MCV with RDW, the cut off value were 83fl of MCV and 14.3% of RDW, and the sensitivity and specificity were 76.3% and 71.3%, respectively. CONCLUSIONS: The sensitivity and specificity of MCV, RDW and combination of MCV and RDW were not so high in discriminating IDA from the anemia of the other causes in ambulatory patients.
