Intraperitoneal adminstration of radioisotopes is suggested to treat the metastatic ovarian cancer in the pertioneal cavity. Administering beta-emitting radioisotopes into the pertioneal cavity allows the maximum energy delivery to the cancerous cells of the pertioneal wall surface while sparing the normal cells located in deep site of the peritoneal wall. In this study, dose estimates of the peritoneal wall are provided to be used for prescribing the amount of 166Ho-chitosan complex administered. The 166Ho-chitosan complex diffused in the peritoneal fluid may attach to the peritoneal wall surface. The attachment fraction of 166Ho-chitosan complex to the peritoneal wall surface is obtained by simulating the ascites with Fischer rats. Both volume source in the peritoneal fluid and the surface source over the peritoneal wall surface are counted for the contribution to the peritoneal wall dose. The Monte Carlo code EGS4 is used to simulate the energy transfer of the beta particles emitted from 166Ho. A plane geometrical model of semi-infinite volume describes the peritoneal cavity and peritoneal wall. A semi-infinite plane of 10 micrometer in thickness at every 1 mm of depth in the peritoneal wall is taken as the target in dose estimation. Greater han 98 percents of attachment fraction has been observed from the experiments with Fischer rats. Given 1.3 microcurie/cm2 and 2.4 microcurie/ml of uniform activity density, absorbed dose is 123 Gy, 8.59 Gy, 3.00 Gy, 1.03 Gy, and 327 Gy at 0 mm, 1 mm, 2 mm, 3 mm, and 4 mm in depth to the peritoneal wall, respectively.

Thin-layer (uni-dimensional and bi-dimensional) chrornatography studies were performed on 60 brownish stockings from 12 companies in Korea to search for Disperse Yellow 3 and Disperse Orange 3, which are known as common sensitizers in textiles. The results were as follows : 1) Mixture of various-colored dyes were being used to reveal the brownish hue in the stockings. 2) TLC demonstrated the presence of Disperse Yellow 3 in 53 stocking. 3) TLC demonstrated the presence of Disperse Orange 3 in 3 stockings, Although lack or more sophisticsted tests such as spectroseopic, infra red or nuclear spectra identification. These results suggest a strong clue to the presence of Disperse Yellow 3 and Disperse Orange 3 in the commercial stocking now being used in Korea.

BACKGROUND: Urography(IVU) is considered the best first investigation in patient with suspected urinary calculi, but recently ultrasonography(USG), combined with a plain film of the abdomen, has been suggested as an alternative. METHODS: We undertaken study to see if this approch can be used in emergency patients and outpatients by radiologists with different amounts of ultrasound experence. Some 192 patients with suspected urinary colic presenting to Koo Hospital Emergency Department and Youngnam Universith Hospital outward Department(IM, URO, FM) over 12-month period were studied. They had a plain abdominal film(KUB) and USG examination of the kidney, ureter, bladder following hydration and subsequently underwent IVU. Of these, 22 patients passed a stone before their IVU. The data analysis was performed on the remaining 170 patients. Urography was used as the gold standard. RESULTS: Some 170 patients subsequently underwent IVU at a mean interval of 1.8 days after the ultrasound examination. In 91 of 170 patients the IVU was positive. In 97 of 170 patients the combination of JUB plus USG was positive, leaving three false negative KUB plus USG. Thus the sensitivity of KUB plus USG was 97%, specificity was 89%, positive predictive value was 91%, and negative predictive value was 96%. CONCLUSIONS: Our findings in this study suggest that in the hydrated patient the combination of KUB plus US is a very sensitive and relative specific screening test. Because of the high negative predictive value of KUB plus US, urography is not likely to be helpful when KUB plus US are negative. Urography is indicated only if KUB plus US findings are equivocal or if intervention is necessa.ry.

The superior oblique tendon sheath syndrome was first described by Brown(1950). The essential feature is a limitation of elevation in adduction caused by a short or inadequately mobile anterior segment of the superior oblique tendon and its sheath, which restricted passive elevation in the fully adducted position. Brown has subdivided the entity into true and simulated Brown's syndrome. True Brown's syndrome may be typical or atypical. Typically, there is no significant co-existing limitation of the homolateral superior rectus muscle; atypically there is a significant limitation. Numerous surgical techniques have been advocated to treat Brown's syndrome. Of these, a tenectomy of the homolateral superior oblique has emerged as the most effective method. The authors experienced two cases of Brown's syndrome, one is typical in 5 year old male patient, the other is atypical in 27 year old male patient. Excellent result was obtained in typical Brown's syndrome who underwent a tenectomy of the superior oblique, including the sheath.
