To evaluate the relationship between coronary artery disease(CAD) and the various levels of lipid and lipoproteins, we performed coronary angiography to the patient, who were suspected coronary artery disease from January 1988 to August 1989. And compared it with normal control group. The number of control group were 41(21 men, 20 women), and the patient group were 52(42 men, 10 women). The age was not differ between two groups. The results were as follows; 1. In CAD group, the plasma concentration of total lipid, triglyceride, total cholesterol, phosphlipid, and TC/HDL ratio were significantly higher than in control group. But, though, the concentration of HDL was lower in CAD group, had no significant difference between two groups. 2. The severity of CAD were well correlated with total lipid, cholesterol, LDL, trigylceride, phospholipid, TC/HDL, LDL/HDL levels. HDL level didnt's show significant correlation with the degree of CAD. We concluded that total lipid, cholesterol, trigylceride TC/LDL ratio were valuable markers of CAD in Korean, but futhur studies of lipoproteiins and other risk factors in the large population will be recommended.

Background: Recently, patients' demands for emergency medicine are increasing, and most of prehospital medical care, including basic life support, cardiopulmonary resuscitation and triage, are provided by paramedics or emergency medical technicians. Evaluation of the adequacy of prehospital management and triage has become important for improving the quality and the effectiveness of the emergency medical system. Methods: The 202 patients who were transferred by ambulance with paramedics, nurses, or emergency medical technicians to the Emergency Department in Gil Medical Center from July 1, 1999, to September 31, 1999, were enrolled. This study was conducted prospectively by using the emergency physician,s log and newly devised protocols recorded by paramedics or nurses. Results: 1) Male to female ratio was 1: 0.8, and the peak age of the patients were the 4th(18.8%) and 6th decade(15.3%). 2) Of the 202 patients, 84 patients were transferred for trauma and 118 for medical problems. The mean transfer time was 6±1.73 minutes. 3) The validities of prehospital triage and decisions using the trauma severity measure and the disease severity measure, were 33.3% in trauma patients and 57.6% in medical patients.4) The results for the adequacy rate in prehospital management analyzed by using the rate of necessity of treatment. performance of treatment, and adequate treatment were as follows: oxygen supply.38.1/41.6/93.8 ; wound dressing. 19.3/71.8/92.9 ; immobilization of the cervical spine, 15.8/56.3/92.9 ; application of a spinal board. 12.9/42.3/72.7 ; application of a splint, 9.9/50.0/60.0 ; manual maintenance of an airway. 9.9/55.0/63.6 ; and CPR, 4.5/66.7/0. 5) Kind of ALS(Advanced Life Support) were not conducted(peripheral IV, EKG. intubation, medical administration. defibrillation, pacing). The rates of necessity of treatment were as follows: peripheral IV, 40.6%; ECG monitoring, 23.3% ; endotracheal intubation, 8.9% ; medical administration, 8.9% ; defibrillation. 3.5%; and pacing. 1.5% Conclusion: The adequacy of prehospital triage and decisions using trauma and disease severity measures was relatively low. To improve the adequacy of BLS(Basic Life Support) and to increase the performance of ALS(Advanced Life Support), we must create challenges to develop new protocols and to supplement new equipment.

The purpose of this study was to determine the physiological characteristics and anaerobic threshold of world-class judo players(10 males and 10 females) on two types of ergometer, treadmill and stationary bike, using a garded exercise test to the maximal level. The results of this study are as follows; 1. Maximal oxygen uptake(VO2max) of male and female subjects were 60.67 ± 2.96%ml/kg/min(4.40 ± 0.28l/min) and 47.18±3.87ml/kg/min(2.81±0.11l/min) respectively. Maximal heart rate(HRmax) of male was 181.90 ± 5.88beats/ min and female 166.75 ± 8.30beats/ min. 2. Anaerobic thresholds were occurred at 85.22±3.81%(male) and 91.88±0.99% (female) of HRmax, and at 76.30±4.79%(male) and 80.45±1.45%(female) of VO2max. These results showed that the endurance capacity of male subjects was relatively lower than that of female subjects. This can be caused by the unique training styles of male and female judo players due to the different styles of these male and female matches. The matches of males tend to the decided in a relatively shorter time because of their stronger muscular strength and power compared to those of female.

Despite intensive investigation into paraquat toxicity, neither the final cytotoxic mechanism nor a clinically useful antidote has been discovered. The mechanism of paraquat cytotoxicity is also debatable, but it is generally accepted that a redox reaction occurs between reduced paraquat and molecular oxygen. The intracellular reduction of paraquat occurs by various enzymes, such as DT-diaphorase, xanthine oxidase and glutathione reductase. In present study, we investigated that the effects of allopurinol, a xanthine oxidase inhibitor, and dicumarol, a DT-diaphorase inhibitor, in paraquat-intoxicated rats. The survivals of paraquat-intoxicated rats were increased by allopurinol treatment compared to paraquat-treated control rats , but not effected by dicumarol treatment. The activity of xanthine oxidase in the liver of allopurinol-treated rats was decreased and DT-diaphorase activity in liver of dicumarol treated rats was also decreased compared to normal control rats. The contents of glutathione in liver of paraquat treated rats was decreased but in paraquat+allopurinol treated rats, the decrements of glutathione contents was reduced but in paraquat+dicumarol treated rats, liver glutathione level was not changed compared to paraquat-treated rats. These results suggest that paraquat toxicity maybe reduced by administration of allopurinol but dicumarol did not have such effects .
