Recently it has been stated that animals without ischemic arrhythmia would be at almost no risk for reperfusion ventricular fibrillation(VF) in contrast to animals with ischemic arrhythmias. In order to observe the differences of ararrhythmias characteristics between ischemic and reperfusion period, and correlationship between occlusion and reperfusion arrhythmias, the left anterior descending(LAD) coronary artery was occluded for 20 minutes and reperfused for 10 minutes in 24 anesthetized cats. The results were as follows; 1) After ligation of LAD coronary artery, the R wave, S-T segment and T wave of epicardial EKG were elevated to reach maximum level at 5-10 minutes. 2) During reperfusion, the changes of R wave, S-T segment, and T wave of epicardial EKG were not significant. 3) The incidence of arrhythmias at early phase and late phase of occlusion period were 41.6% and 100% respectively. The ischemic arrhythmia score was 2.38+/-1.61 and incidence of ventricular tachycardia(VT) was 66% 4) The incidence of VT and VF during reperfusion was 100% and 62.5% respectively. The reperfusion arrhythmia score was 5.88+/-1.72. 5) The two morphologies of ventricular arrhythmias were observed at occluson and reperfusion period. 6) The disparities between occlusion and reperfusion arrhythmias were observed. 7) The cats with shorter R-R internal and/or lower systolic left ventricualr pressure had the higher incidence of VF. In summary, although the morphology of occlusion ventricular arrhythmias was similar to that of reperfusion ventricular arrhythmias, the lack of correlation between reperfusion VF and ischemic arrhythmias was observed. So we suggest that further studies which provide the different mechanisms involved in occlusion and reperfusion arrhythmias were needed.

Clinical analysis is done on 108 meniscus injuries operated on at Kwangju Armed Forces General Hospital from 1961 to 1971, with the following results. l. All cases included in this report were military personnels aged from 19 to 35 years old 2. The lateral meniscus was more frequently injured than the medial with a ratio of 79 to 29 (8:3) and the right side knee than the left with a ratio of 60 to 48(6:5). 3. The posterior horn tears were the most common type of injuries involved in 40 cases (41%) 4. There could be found no history of definitive trauma in l7 cases.

The effect of amiodarone on reperfusion arrhthmias after release of left anterior descending coronary artery(LAD) occlusion was studied in 22 anesthetized cats. All cats underwent 20 minutes LAD occlusion followed by reperfusion and amiodarone(20mg/Kg) or normal saline was given on cats which had reperfusion arrhythmias through the left ventricular catheter to observe the antiarrhythmic effect of amiodarone. And also the incidence and type of arrhymias during occlusion and reperfusion were analyzed. During the 20 minute LAD occlusion, 10 of 22 cats(45%) had no arrhythmias, and 12 cats(55%) had nonsustatined ventricular tachycardia. After release of occlusion, 5 of 22 cats(23%) had no arrthmias, and 17 cats(77%) developed sustained ventricular arrhythmias(ventricular tachycardia (n=5), ventricular fibrillation(n=12)). The 17 cats which had reperfusion arrhythmias were randomly divided and given normal saline(control(n=8)) or amiodarone(amiodarone group(n=9)). There was no difference on 2 groups. The reperfusion arrhythmias disappeared in 6 out of 9 cats(66.7%) vs none of 8 controls(P<0.01). We conclude that amiodarone seems to be the effective antiarrhythmic drug on reperfusion arrhythmias after release of LAD occlusion in anesthetized cats, and might be useful for the treatment of reperfusion arrhythmias in human.

Atypical fibroxanthoma(AFX) occurs most on sun-exposed area of the head and neck of elderly person. It has an excellent prognosis after conservative, but complete, excision. However, because of its potential, albeit small, for metastasis, it is widely regarded as a low-grade sarcoma. We present herein two cases of atypical fibroxanthoma. The case 1 was a 86-year-old female who had a small egg-sized, dome shaped nodule with eroive surface on the left cheek. The other case was a 60-year-old male who had solitry bean-sized, nodulo-ulcerative lesion on the vertex. Immunohistochemical studies revealed positive reaction for vimntin and a-antichymo trypsin. These patients have received completely total surgical ecis on and remained free of recurrence for a period of about, 2 years follow up.

In an attempt to find out the effect of epidural administration with morphine on postoperative pain relief, a small dose of morphine with a local anesthetic(lidocaine) was administered into the epidural space, either by lumbar or caudal approach. Morphine injected into the epidural space has been suggested to produce it's effect by direct action on the specific oplate receptor in the substantia gelatinosa of the posterior horn of the spinal cord. 90 patients who were anesthetized under epidural block in the Pusan Paik's Hospital, INJE Medical College, from May 1980 trhough Jan. 1981 were divided into the groups "Lidocaine alone" and "Lidocaine + Morphine". The number of patients of patients of the lumbar approach was 73 (81.1%) and of the caudal approach was 17(18.9%). The group "Lidocaine alone" numbered 45 cases which were injected with 2% lidocaine into the epidural space as an anesthetic. Group "Lidocaine + Morphine" also numbered 45 cases and received 2mg of morphine with 500 mg of 2% lidocaine as an epidural anesthetic. 0.2mg of 0.1% epinephrine was mixed to the anesthetic solution in all the above cases. The results of this study are as follows: 1) Alteration of arterial blood pressure during anesthesia was minimal within 30 minutes after injection of the epidural anesthetic in both groups. 2) Duration of postoperative pain relief in the group "Lidocaine + Morphine" was significantly extended comparing it to that in the group "Lidocaine alone". 3) Between the two groups, no significant difference was noted in recovery of spontaneous volding. 4) Complications were similar in both groups except for nausea and vomiting which occurred more frequently in the group "Lidocaine + Morphine"(8.9% and 6.7%, respectively) than in the group "Lidocaine alone" (2.2% and none, respectively). Any signs of CNS depression or neurologic sequelae were not observed.
