PURPOSE: To evaluate the relative value of arterial, portal venous and delayed phase images of spiral CT in the detection of metastatic tumor of the liver. MATERIALS AND METHODS: Forty-three metastatic tumors in twelve patients were underwent tri-phasic spiral CT examination with injection of 120 ml ionic contrast material (36 g of iodine) at the rate of 3 ml/sec. Arterial, portal venous and delayed phase CT images were obtained 35, 65, and 360 seconds after the start of contrast injection, respectively. RESULTS: Arterial phase images detected 35(81%), portal venous phase images 43(100%), and delayed phase images 34(79%) lesions, respectively(p<0.05). All masses larger than 2cm(n=23) were detected in all three phases, whereas 60%, 100%, 55%of the masses smaller than 2cm(n=20) were detected in arterial, portal venous and delayed phase CT, respectively. The best contrast between masses and the hepatic parenchyma was in portal venous phase followed by arterial and delayed phase(p<0.01). In two hypervascular masses, the contrast was better in arterial phase. CONCLUSION: Portal venous phase of spiral CT is optimal in the detection of metastatic tumor of the liver. Arterial phase may be helpful for the detection of hypervascular metastasis. Delayed phase should be used restrictively.

Two cases of old unreduced dislocation of shoulder are reported. One was the posterior dislocation for six months with malunited fracture of humeral shaft in thirty degree lateral angulation. Her shoulder and arm aches with limitation of motion remaining only ten degrees in every direction but abduction in thirty degrees, The malunion of humeral shaft and shoulder were reduced surgically in result of eighty degrees abduction, seventy degrees flexion, sixty degrees extension and twenty degrees of external rotation with free of pain. Another case was an anterior dislocation for one year. Her range of shoulder motions are almost normal degree but brachial plaxus compression symptoms. Open reduction in practically Putti-Platt procedure was performed. She became completely free of brachial plexus symptom and ranges of shoulder motion are normal except about fifteen degrees less external rotation than preoperative condition. The surgical indication and the result of treatment were discussed for the the neglected cases of old unreduced dislocation of the shoulder.

Most patients who have spondylolysis dont's need surgical treatment. However, for the patients who have no response to conservative treatment, surgical treatment may be indicated. In 1970, Buck reported the operative technique that the used two screws between the pars defect and lamina followed by bone graft. In patients who have spondyloysis, pain in the back seems to be due to instability and irritation of nerve root by the abnormal motion of the loose neural arch and granulation tissue. For period of 7 years from May, 1984 to March, 1991, twelve patients with spondyloysis who had no response to conservative treatment were treated with Buck's operation and were analyzed. Following results were obtained: 1. The age of the patients was 24 years in average ranging from 14 to 40 years. 2. The level of the lesion was L5 in 10 cases, L4 in 2 cases. 3. Preoperative clinical feature included low back pain in 12 cases, refered pain in 2 cases. 4. Clinical sympotoms were improved in 83%, and the follow up result of the operation: excellent 16.7%, good 66.6% and poor 16.7%.

The purpose of this study was to estimate average lacrimal gland size on computed tomography in korean. The subjects were 137 Koreans who were checked orbital CT in Department of Ophthalmology, Soonchunhyang University School of Medicine from June 1990 to August 1994. The average width of lacrimal gland was 17.15 +/- 1.75mm, A-P length was 9.81 +/- 1.65mm and thickness was 4.57 +/- 0.99mm. The average width, A-P length and thickness of lacrimal gland were not statistically different between males and females(p>0.05).

PURPOSE: To verify the usefulness of left portal vein angle (LPVA) on CT scan in the diagnosis of liver cirrhosis and to compare its diagnostic value with that of caudate to right lobe ratio (C/RL ratio). MATERIALS AND METHODS: LPVA, an angle formed by a vertical line and a line connecting the center of the vertebral body to the umbilical point of the left portal vein, and C/RL ratio were measured on CT scans of 100 cirrhotic and 100 normal livers. Diagnostic values of LPVA and C/RL ratio were compared statistically. RESULTS: The mean of LPVA was 18.9 degrees(SD; 7.6) for normal livers and 25.8 degreesSD; 8.4) for cirrhotic livers (P<0.001). The mean of C/RL ratio was 0.47(SD; 1.10) for normal livers and 0.58(SD;0.14) for cirrhotic livers (P<0.001). When LPVA was greater than 30 degreesliver cirrhosis was diagnosed with 36% sensitivity and 92% specificity. When C/RL ratio was greater than 0.60, the diagnose of liver cirrhosis was with 41% sensitivity and 90% specificity. There was no significant difference of the diagnostic accuracy between LPVA and C/R L ratio in ROC analysis. CONCLUSION: Both LPVA and C/RL ratio are useful diagnostic indices of liver cirrhosis on CTscan. LPVA is more convenient to measure than C/RL ratio.

Kerion celsi is severe inflammatory type of tinea capitis. It occurs almost exclusively in pre-pubertal children. We report a case of Kerion celsi occuring in a 79-year-old woman. Culture of infected hair on Sabouraud glucose agar showed Microsporum canis Farnily history and fungus study suggested the importance of indirect route in Microsporum canis infection.

Extravasation of toxic chemotherapeutic 'agents cause severe skin ulceration and necrosis which often need secondary surgical intervention. Still, there were not established antidote agent in case of extravasation with mitomycin-c. Dimethyl sulfoxide is known as an effective chemical scavenger of toxic hydroxyl free radical and sodium thiosulfate also was demonstrated significant protector from mitomycin-c induced ulceration by a few experimental studies. Author investigated necrotic area of mitomycin-c injected site and compare to the effectiveness of topical treatment with dimethyl sulfoxide and intradermal injection of sodium thiosulfate according to starting times, forty five mice were divided into 3 groups. Control group(n=5) had no treatment after subcutaneous injection of mitomycin-c. Experimental group I and 11 were 20 mice treated dimethyl sulfoxide and sodium.
