PURPOSE: To analyze the characteristies of traumatic brainstem injury by CT and MR MATERIALS AND METHODS: CT and MR studies of 10 patients with traumatic brainstem lesion in MR were retrospectively reviewed, particularly attended to location, signal intensity and associated lesions. RESULTS: CT failed to depict 8 of 10 brainstem lesions. All lesions were detected in MR images with T2-weighted images showing higher detection rate (n=10) (100%) than Tl-weighted images (n=3) (30%) or CT (n=2) (20%). The brainstem lesions located in the dorsolateral aspects of the rostral brainstem(mid brain and upper pons)in 7 (70%) cases, in ventral aspects of rostral brain in 2 (20%) cases and in median portion of pons in 1 (10%) case. Corpus callosal (n=5), Iobar white matter(n=5) diffuse axonal injury, and 2 hemorrhagic lesions in basal ganglia were the associated findings. CONCLUSION: MR imaging is more helpful than CT in the detection of brainstem injury, especially T2 weighted images. Primary brainstem lesions were typically located in the dorsolateral aspect of rostral brainstem(midbrain and upper pons). Corpus callosum and white matter lesions were frequently associated.

Sparganosis is a rare tissue-parasitic infestation caused by a plerocercoid tapeworm larva(sparganum), genus Spirometra. The most common clinical presentation of sparganosis is a palpable subcutaneous mass or masses. Fifteen simple radiographs and 10 ultrasonograms of 17 patients with operatively verified subcutaneous sparganosis were retrospectively analyzed to find its radiologic characteristics for preoperative diagnosis of sparganosis. The locations of the subcutaneous sparganosis were lower extremity, abdominal wall, breast, inguinal region and scrotum in order of frequency. The simple radiographs showed linear or elongated calcification with or without nodular elongated shaped soft tissue mass shadows in 8 patients, soft tissue mass shadow only in 2 patients and lateral abdominal wall thickening in 1 patient. But no specific findings was noted in 4 patients with small abdominal and inguinal masses. We could classify the subcutaneous sparganosis by ultrasound into 2 types: one is long band-like hypoechoic structures, corresponding to the subcutaneous tunnel-like tracks formed by migration of sparganum larva and the other is elongated or ovoid hypoechoic nodules, representing granulomas. Long band-like hypoechoic structures within or associated with mixed echoic granulomatous masses were noted in 6 patients and elongated or ovoid hypoechoic mass or masses were noted in 4 patients. In conclusion, sparganosis should be considered when these radiologic findings-irregular linear calcifications on simple radiograph and long ban-like hypoechoic structures on ultrasonography, corresponding to the subcutaneous tunnel-like tracks formed by migration of sparganum larva-are noted in the patients who have subcutaneous palpable mass or masses. And radiologic examination especially ultrasonography is very helpful to diagnose sparganosis.

The author evaluated the optimal concentration of 3 compositions of TIC medium which has used as the melanacytes culture medium. The concentrations of placental extract and bovine pituitary extract, which have the ability to promote proliferation of melanocytes, were evaluated also. Modified TIC medium with above 5 components of evaluated concentration was very effective in melanocytes culture. The results were as follows : l. 12-0-tetradecanoyl-phorbol-13-acetate (TPA) showed effective melanocytes proliferating activity at the concentration of 30ngml (p(0.05) 2. Isobutylmet:hyl xanthine (IBMX) showed effective melanocytes proliferating activity at the concentration of 0.3mM (p(0.05) 3. Cholera toxin (CT) showed effective melanocytes proliferating activity at the concentration of )OnM (p(0.05) 4. Two percentages of placental extract in culture medium showed effective melanocytes proliferating activity. S. Two percentages of bovine pituitary extract in culture medium showed effective melanocytes proliferating activity. 6. Placental extract and isobutylmethyl xanthine proved to have high melanocytes proliferating activity. 7. Melanocytes proliferated rapidly on modified TIC medium (Proliferation doubling time . about 43 hours) 8. The peak time of melanocytes proliferation (7.2 X 10/cm) was observed on the seventh day of culture, From this data, this culture system can be recommended as a new melanocytes culture.

Strongylodiasis is universal in distribution but is most abundant in countries with a tropical climate. Although infestation by Strongyloides stercoralis is usually limited to the intestines, dessemination of this helminth in debilitated host can be lead to death with various clinical disorders. characterized by profound malabsorption, diarrhea, electrolyte imbalance, gram negative or opportunistic fungal sepsis, coma and death. Cell-mediated immunity contributing significantly to the control of helminthic infections, may be suppressed by carcinoma, immunosuppressive chemotherapy and use of corticosteroids. Diagnosis of Strongyloidiasis is achieved by an examination of samples of feces, duodenal aspirates and sputum of patients for Strongyloides stercoralis. Treatment of strongyloidiasis is twofold : correction of the immunosuppressive state by withdrawal of immunosuppressive drug, if possible, and vigorous treatment with thiabendazole. Testing for strongyloidiasis is especially recommanded before treating a patients should be monitored for infection by Strongyloides stercoralis and other opportunistic infection. We are reporting a case patient with Strongyloides stercoralis hyperinfection and pulmonary tuberculosis who had been. used corticosteroid for persisting polyarthritis.

For the study of correlation of CT number and fatty content of the liver, total 35 rabbits were used. Therabbits were divided into one control and three experimental groups according to the amount of carbonetetra choloride, administered 1ml, 2ml and 3ml per kg lf body weight respectively. The carbone tetrachloride wasadministered via intragastric route. CT was performed 72 hours following administration of carbone tetrachloride,and immediately prior to CT scan each rabbit was anesthetized by means of IM injection of ketamine and IV injection of succinylcholine to stop motion and respiration. CT numbers were measured and histological study forthe deposition of fat in the liver tissue was done. Also biochemical analysis of lipid in the blood and in theextraction of liver tissue was performed. Comparison of CT number with biochemical and histological data was done.The results were as follows: 1. In each experimental group, the degree of accumulation of fat in the liver was proportional to the amount of carbone tetrachloride. 2. Degree of decreaseing CT number was correlated with theincrease in the accumlation of fat in the liver. 3. In the control and experimental (1,2,3) groups, when theamount of carbone tetrachloride increased, the amount of total lipid, cholesterol and triglyceride on biochemical analysis of the liver increased. Also increase in the amount of plasma lipids on biochemical analysis and a greatdegree of increase in accumulation of fat in the liver on histological examination were see. But no changes in theamounts of phospholipid and protein on biochemical analysis of the liver were noticed. 4. Increase in the amountof total lipid could make a change in the CT number of the liver remakably(r=−0.63). As the amount of cholesteroland triglyceride increased, the CT number of the liver decreased (r=−0.61 and r=−0.76 respectively). But there wasno significant correlation between the amount of protein and phospholipid and the degree of decrease in CT number.5. Mean values of CT number in normal, grade 1, grade 2, grade 3 and grade 4 according to the degree ofhistological changes were 67.46±2.24, 58.53±3.06, 49.43±6.91, 39.49±9.69, 20.62±8.04 respectively. Thereduction of CT number was correlated with the accumulation of fat on histological examination.

Releasable suture was used to control anterior chamber depth and intraocular pressure during early postoperative period following trabeculectomy. Failure of releasable suture removal was due to entrapping of the tissue into suture knot or fibrosis between suture and surrounding tissues. Hence, the authors compared the failure rate of transconjunctival releasable suture and transcorneal releasable suture in trabeculectomy. The authors evaulated the 60 eyes of 60 patients undergoing trabeculectomy. Of these eyes, 30 eyes did not use Mitomycin C and transconjuctival releasable suture(15eyes) and transcorneal releasable suture(15eyes) at 2weeks after trabeculectomy, and the other 30 eyes used Mitomycin C and were removed transconjuctival releasable suture(15eyes) and transcorneal releasable suture(15eyes) removed at 4 weeks after trabeculectomy. With Mitomycin C, failure rate of releasable suture removal was 87% in transconjunctival releasable suture and 33% in transcorneal releasable suture. Without Mitomycin C, failure rate of releasable suture removal was 73% in transconjunctival releasable suture and 7% in transcorneal releasable suture. Recently, we have commonly used thin suture material such as 10-0 nylon and with use of antimetabolite let releasable suture was removed at late time. We suggest that transcorneal releasable suture can reduce the fibrosis of subconjunctival tissue and reaction between suture material and subconjunctival tissue.
