Giant-cell tumor is considered one of the benign tumors which is predilected at an ends of a long bone. Although many reports of giant-cell tumor affecting the sacrum have been recentIy presented, the report of the tumor involving coccyx is not comparatively frequent. A case of relatively uncommon giant-cell tumor involving the coccyx is presented with the review of the relevant literature.

Recently there is increasing tendency of the nosocomial infection, and Pseudomonas aeruginosa is one of the most important and common pathogens causing hospital opportunistic infections with rapid emergence of resistant strain especially in immunologically compromised patients. An experimental study for the effects of polyvalent Pseudomonas vaccine was performed in an animal model of Pseudomonas sepsis on a survival rates and histopathological points of view-using ICR inbred mice. The vaccine was prepared with heat killed whole cells of the 10 representative serotypes of Pseudomonas aeruginosa, which were isolated from the Department of Microbiology, College of Medicine, Kyung Hee University and Seoul National University, and they were devided into two polyvalent vaccine groups. The animal model of the Pseudomonas sepsis was deveoped by intravenous inoculation of Pseudomonas aeruginosa (serotype F, inoculum size 100 microliter, 109 cells/ml), immediately after cutaneous burns. The results were as follows. 1) The survival rate of the immune mice was 100% and that of non-immune mice was 60%. 2) The histologic findings of lung of the non-immune mice were severe congestion (18/18 mice), hemorrhage (18/18 mice), emphysematous change (18/18 mice), thrombosis (9/18 mice), infarction (9/18 mice) and inflammation (6/18 mice) and those of the immune mice were only congestion (6/20 mice) and focal emphysematous change (2/20) from the 3 day experimental group. 3) The histologic findings of the liver in the non-immune mice were severe congestion, Kupffer cell mobilization, focal necrosis, & portal inflammation in most of them, and from 7 day experimental group there were noted infiltrations of lagre histiocytic cells in sinusoids, and those in the immune mice were only reactive change of varying degree. 4) The histologic findings of the spleen in the non-immune mice were severe reactive hyperplasia in all and ischemic necrosis in about half of them, and those in the immune mice were only reactive change. 5) The histologic findings of the heart in the non-immune mice were severe congestion and inflammation in most and in the immune mice were only occasional nonspecific congestion. 6) The histologic findings of the kidney in the non-immune mice were severe congestion in all, interstitial inflammation, acute tubular necrosis and cortical necrosis in about half of them, and those in the immune mice were only mild congestion. With the above results, we can suspect there is a significant protective effects of the polyvalent pseudomonas vaccine on the pseudomonas sepsis in ICR mice.

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.

Romberg syndrome is a rare disease and characterized by unilaeril atrophy of the skin, subcutaneous tissue and the underlying structure of half the face. The lesion does not usually cross the midline of the scalp. Roriberg syndrome is sometimes mildsnosed as linear scleroderma, although they differ widely in their clinical and histological apperance. A 13-year-old boy was present with a one year history of idefined atrophic patch on the left side of face and neck. We involved skin was not bound down to the underlying structure. The history revealed no prcvious trauma or disease, He had no abnormal neurologic finding. Computerized tomography demonstrated a diminished subcutaneouat volume and also decreased thickness of back muscle is the left side face from cheek to neck.

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.

The paroxysmal kinesigenic choreoathetosis is characterized by choreathetoic, dystonic and/or tonic movements induced by sudden voluntary movements, without loss of consciousness, urinary incontinence and clonic movement. These attacks begin in childhood, and are occasionally familial. The response to anticonvulsants is usually excellent. We present 4 cases of paroxysmal kinesigenic choreoathetosis with a brief review of literature, which is believed to be the first report in Korea.

This study was designed to observe more closely about clinical course, complication, predilection site of skin eruption and associated diseases with herpes zoster. Total 122 cases of herpes zoster were prospectively observed from April 1986 to July 1987. The results obtained were as follows : 1. The ineidence of herpes zoster versus the total number of outpatients was 20.6%. There was no difference in sex ratio of male(52.5%) to female(47.5%). 2. Herpes zoster was observed most frequently in the 50-59 year age group (25.4%). 3. There were no marked monthly or seasonal difference in herpes zoster without an explosive outbreak or an epidemic cycle. 4, We found that 68 cases(55.7%) were associated with underlying diseases : the most common disease was hypertension(23 cases), the next one was malignsncy(10 cases), namely, lung cancer, Hodgkin's lymphoma, other malignant lymphoma, leukemia and mediastinal mass, and the other diseases were tuberculosis of intenal organs, diabetes mellitus, hepatic diseases, cardiac diseases, chronic pulmonary diseases, cord injury, gastric ulcer, brain damage, burn, renal diseases, rheumatoid arthritis, and measles. 5. It was suggested that the distributuon of skin lesion were related to dermatome. The incidence of skin lesion was distributuon in the following region in order : T5-T8(25.4%), C6-T4(24.6%), Cl-C5(20.5%), Ll-S3(13.9%), Vl-V3 (12.3%), and T9-T12(3.3%), there was involvement of the entire thoracic dermatome(C6-T12) in 65 cases(53.3%). A great many cases of malignancy, chronic pulmonary disease, cardiac disease, tuberculosis and gastric ulcer were most frequently distributed in the thoracie dermatome, but the involvement of ophthalmic dermatome was found only in the patients with hypertension. 6. The most common complication was postherpetic neuralgia for 31 cases(25.4%) with the highest frequency in 60's(32.3%). Other complications were ophthalmic complication, Ramsay-Hunt syndrome, secondary bacterial infection, moter nerve involvement, difficulty of urination, and recurrent herpes zoster.

Mucormycosis is an infectious disease caused by fungi of the order Mucorales. Almost all patients have a serious uriderlying condition such as diabetes mallitus, imrnunosuppression, starvation, burn, but a few cais have been reported in previously heilthy subjects. In order to successfully treat this infection, diagnosis must be prompt and acior. panied by aggressive debridement and parenteral administration of amphotericin B. We report a case of primary cutaneous mucormycosis in 58-year-old man. The lesion was a well-circumscribed erythematous plaque with central necrcis Histopathologically, a biopsy revealed broad, nonsptate with branches occuring at right anghles.
