The clinical effect of etafenone on 12 cases of angina pectoris(9 males and 3 females with average age of 58.3 years) were studied and following results were obtained: 1. Anginal chest pains were improved after average 9 days (3~15 days) of medication and the dreug was very effective in 41.7%, moderately effective in 33.3% and slightly effective in 25.0% of cases. 2. The ST segment depression of E.C.G. were reduced in 50.0%, improvement of T waves inversion or enlargement of T waves were observed in 66.7% and E.C.G. improvement either ST segment or T wave observed in 75.0% of cases. 3. No side reactions such as hypotension, palpitation, dizziness, headache or gastrointestinal disturbances were seen during the treatement with etafenone.

Neurilemmomas of the extremities are nerve sheath tumors involving peripheral nerves of the extremities. We analyzed MR images of 16 surgically proved tumors in 12 patients and compared the MR images with gross pathologic specimens in two tumors (2/16). Spin echo T1-weighted images were obtained in all the patients but T2-weighted images were obtained in six patients with a gradient echo technique. Gadolinium dimeglumine enhanced T1-weighted images were obtained in 11 patients (15/16). Signal on T1-weighted images was iso or slightly higher than that of the adjacent muscles. Signal on T2-weighted images ranged from homogeneous high to heterogeneous. After Gadolinium injection, all the 15 tumors showed enhancement. Small sized tumors were enhanced homogeneously but there was a tendency tobe enhanced heterogeneously to the central portion with peripheral rim enhancement as the size of the tumors increased. Pathologically, the enhanced portion was correlated the with solid protion was correlated the with solid portion of the tumors. Also encapsulation of the mass (12/16), suspended nerve strings (9/16) and bony erosion (1/16) were detected. MR characteristics of neurilemmoma include heterogeniety on enhanced T1 and T2 weighted images, encapsulation, and suspended nerve strings. Signal heterogeneity on enhanced T1 and T2 weignted images may be attributed to the variable cellularity, cystic changes, vascularity and focal hemorrhage of the tumors.

Histopathological diagnosis of brain stem glioma should be performed for the purpose of the determination of its management and clinical course, but its surgical biopsy has been followed by high mortality and morbidity. We performed the tissue sampling for histological examination with BRW stereotaxic system under local anesthesia successfully.

It has been well known that ischemia reperfusion injury to skeletal muscle following an acute arterial occlusion causes significant morbidity and mortality. There are many causes of reperfusion injury, but the oxygen free radicals have a significant role. During ischemia the ATP is catalyzed to hypoxanthine anaerobically and hypoxanthine dehydrogenase is converted to xanthine oxidase under the presence of O2 resulting in the production of cytotoxic oxygen free radical, which are harmful to muscle. The reactivity of superoxide dismutase(SOD), one of the major antioxidant enzymes, is increased against the formation of the superoxide radical during reperfusion. SOD metabolyzes the superoxide radical to H2 O2 and O2.The severity of ischemic damage deports on the duration of muscle ischemia. The reversible changes in the muscle occur afar 2 hours of ischemia and recover within 24 hours after reperfusion. After 6 hours ischemia, irreversible damage occurs and causes necrosis of muscle. The authors performed the resent study to investigate the changes of Mn-SOD and the effects of allopurinol, the inhibitor of xanthine oxidase, by measuring the immunoreactivitiy of the ischemic reperfused rectus femoris muscle of rats after 2 hours and 6 hours ischemia and timely reperfusion. A total of 176 healthy spraque-Dawley rats weighing from 200 gm to 250 gm were used. Under urthane(3.0 gm/kg.,IP) anesthesia, a lower-abdominal incision was made and the left common iliac artery was ligated by using a vascular clamp for 2 hours and 6 hours. Rectus femoris muscle was obtained at 0 hour, 1 hour, 2 hours, 24 hours, and 48 hours after removal of the vascular clamp. The specimens were sectioned in 14micro miter thickness with a cryostat. The immunoreactivities of Mn-SOD were observed by using Mn-SOD antibodies. The result were as follows. 1. The immunoreactivies of Mn-SOD around sarcolemma were stronger than those on the sarcoplasm. 2. The immunoreactivities of Mn-S0D after 2 hours of ischemia increased to moderate or weak reactivities at 1 hour and 2 hours of reperfusion and returned to week or trace reactivities at 24 hours and 48 hours of reperfusion 3. The pretreatment of allopurinol decreased the immunoreactivies of Mn-SOD during reperfusion. The pattern of changes of SOD immunoreactivies were similar, but the range of changes significantly decreased. 4. The immunoreactivies of Mn-SOD after 6 hours of ischemia increased after 6 hours of ischemia increased after reperfusion and showed peak at 2 hours and 24 hours specimen. After 48 hours in the reperfused group, the reactivities slightly decreased. 5. After 6 hours in the ischemia-reperfused group, the pretreatment of allopurinol decreased the immunoreactivies of Mn-SOD during reperfusion, but the effects were weak. These results suggest that the immunoreactivities of the 6 hours ischemia reperfused group were higher than those of 2-hours ischemia reperfused group in the rectus femoris muscle of rats and that allopurinol pretreatment can be credited with decreasing ischemia reperfusion injury within a reversible period.
