Transcatheter transarterial embolization is one of main scope of interventional radiology for bleedingcontrol, preoperative and devascularization of unresectable tumor. We authors performed Gelfoam embolization in 10cases of various patients including 3 cases of hypernephroma, 2 cases of renal arteriovenous malformation, 2 casesof unresectrable hepatoma, 2 cases of nasopharyngeal bleeding tumors and one case of bleeding urinary bladdertumor, at Department of Radiology, Korea University Hospital. Gelfoam particles were used as embolic material,which were cut into cubes approximately 1.5x1.5x10 mm3 in size, and total volume of used Gelfoam was 1.5cc to 12ccdepending on the nature of disease and size of the feeding artery. Usual angiographic catheter of 5-7F in diameterwere used. In all 10 cases, the embolization was succesful for bleeding control, preoperative preparation ordevascularization of the unresectable tumor. In four cases, postembolization syndrome was developed ascomplication, which were 4 cases of pain on embolization is very helpful for various diseases, and Gelfoam is oneof the useful and conventient absorable embolic material for transcatheter embolization.

To evaluate the radioprotective effects of 5-thio-D-glucose(5-TDG) on normal skin, an experimental study was carried out with total 140 mice, of which 30 mice were given 5-TDG followed by irradiation and 60 mice were given intraperitoneally (IP) two hours before irradiation, and the radiation doses were singly 2500, 3500 or 4500 radsrespectively. The skin changes of the irradiated right hind limb were inspected for 31 days and the skin scores were analized. The results are as follow; 1. Marked radioprotective effect was presented in the group of 5-TDG,1.5g/kg body weight, with 2500 rads irradiation. 2. Definite radioprotective effect was also revealed in the groupof 5-TDG, 1.5kg/ body weight, with 3500 rads irradiation, In the group of double dose 5-TDG, 3.0g/kg body weight, the radioprotective effect appeared to be enhanced. 3. In the group of 4500 rads irradiation with 5-TDG, 1.5g/kgbody weight, no radioprotective effect was noticed. 4. In addition to the radiosensitization effect on the hypoxiccells, the radioprotective effect of 5-TDG on the normal animal tissue suggests increased possiblility of itsclinical application.

Bronchioloalveolar carcinoma may present with a variety of radiographic and clinical appearances. The authors reviewed the radiographs of 17 patients with pathologically proven bronchioloalveolar carcinoma, retrospectively. Seven cases were of the localized form. Among the seven five showed a localized mass and two showed localized consolidation. Ten cases were of the diffuse form. Among the ten, three showed diffuse nodules, two showed diffuse consolidation, and five showed a combined pattern of nodules and consolidations. Progression of disease was observed in 9 patients. In these cases, localized forms progressed to a diffuse forms and nodular patterns progressed to a consolidation pattern. Seven cases of the diffuse form were given antituberculous medications on hospital admission. In summary, bronchioloalveolar carcinoma has varied radiographic patterns, and often mimicks other pulmonary diseases such as pulmonary tuberculosis.

A case of parathion poisoning has been reported; in which the symptoms of hypoxia resulted from partial airway obstruction, however this was mistaken for parathion poisoning, and the correct diagnosis was proved by removal of hard blood clot in the bronchial bifurcation. Conclusions were as follows: Adquate administration of PAM and atropine presented impressive response of symptoms. 2. Careful and frequent removal of secretion might be the most important problem especially in this poisoning. 3. Massive administration of antibiotics could prevent pulmonary complications. 4. Pulmonary edema, the most common complication, was not present.

The present study was designed to define the role of prostaglandin in the development and hatching of mouse embryo. The effects of indomethacin, an inhibitor of prostaglandin synthesis, on the development and hatching of morula and blastocyst were examined. In early morula stage, embryos were degenerated significantly at 100 muM and 200 muM indomethacin. However, :he viability of embryos was not influenced by concentration in any other embryonic stages. In all embryonic stages, the hatching was suppressed with concentration dependent manner, but expansion was not suppressed. Particularly, in 84h embryos post hCG injection, the hatching was suppressed significantly compared with post hCG 72h or 96h embryos. When embryos were treated with 100 muM indomethacin for a specific time (12h) in according to the development stage, the hatching was suppressed all groups. These suppressional effect was decreased as embryonic development stage was progressed. However, the expansion was not affected in all treatment group. This study suggests that hatching-related metabolic substances are synthesized from morula stage and intraembryonic signaling mediated prostaglandin was important for development and hatching of mouse embryo.

Two cases of ureteral fibrous polyp showing serpiginous filling defect on IVP are presented with characteristic radiologic features; easy flow of contrast medium around polyp. Prolapsed polyp in urinary bladder, and less ureteral obstruction or renal damage than in epithelial lesions. These rediologic findings enable to differentiation of ureteral fibrous polyps from malignant tumor, which is helpful for determining therapeutic approach.

Following application of 2N sodium hydroxide to the cornea, the aqueous humor pH reached a maximum of 10.2, 11.9, and 12 within 6 minutes following 20-, 50-, and 100-ul sodium hydrxide burn, respectively: after two hours the pH had fallen to 8.5, 10 and 10.5, The maximum rise following application of 100 ul of ammonium hydroxide was 10.8, declining to about 9 at 2 hours. The fall in pH following a 100-ul sodium hydroxide burn has not greatly influenced by external lavage. However, the pH was significantly lowerd by paracentesis alone and further reduce by immediate or delayed intracameral administration of phosphate buffer. On the basis of these result moderately severe and severe alkali burns of the eye should be treated by paracentesis and if possible with anterior chamber reformation with a sterile solution.
