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.

Hypergammaglobulinemic purpura of Waldenstrom is characterized by recurrent episodes of petechiae, hypergammaglobulinemia, an elevated erythrocyte sedimentation rate, and the presence of rheumatoid factor, and leukocytoclastic vasculitis or mild lymphocytic perivasculitis. There is a primary type and a secondary type which is associated with other autoimmune diseases. We present a csae of a 48 year-old female with hypergammaglobulinemic purpura of Waldenstrom. She showed characteristic clinical, histopathological and laboratory findings consistent with hypergammaglobulinema purpura of Waldenstrom. Although there was a decrease in the Schimer test, we couldt den ostrate an association with Sjogrens syndrome. We think that this case may be a secondary type and needs a follow-up study.

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.

PURPOSE: The differentiation between renal cell carcinoma(RCC) and transitional cell carcinoma(TCC) is important due to the different methods of treatment and prognosis. But occasionally it is difficult to draw a distinction between the two diseases when renal parenchyme and renal collecting systems are invaded simultaneously. MATERIAL AND METHOD: We reviewed CT scans of 37 cases of renal cell carcinoma and 12 cases of transitional cell carcinoma which showed involvement of renal parenchyma and renal sinus fat on CT. Retrospective analysis was performed by 3 abdominal radiologists. Check points were renalcontour bulging or reniform shape, location of mass center, intact parenchyme overlying the tumor, cystic change, calcification, LN metastasis, vessel invasion, and perirenal extention. RESULT:There were renal contour bulging due to the tumor mass in 33 out of 37 cases of renal cellcarcinima, wherea and nine of 12 cases of transitional cell carcinoma maintained the reniform appearance. This is significant statiscal difference between the two(p<0.005). Center of all TCCs were located in the renal sinus, and 24 out of 35 cases of RCC were located in the cortex(p<0.005). Thirty-six out of 37 cases of RCC lost the overlying parenchyma, whereas 4 out of 9 cases of well enhanced TCC had intact overlying parenchyma(p<0.005) RCC showed uptic change within the tumor mags in 31 cases which was significanity higher than the 4 cases in TCC(p<0.05). CONCLUSION: CT findings of renal cell carcinoma are contour bulging, peripheral location, obliteration of parenchyma, and cystic change. Findings of transitional cell carcinoma are reniform appearance, central location within the kidney, intact overlying parenchyma, and rare cystic change.

Herein we analyze retrospectively 21 patients with stage D prostatic adenocarcinoma admitted to our hospital during the period from January 1980 through December 1985. Of the 40 patients who had prostatic adenocarcinoma, 21 (50%) patients were classified as stage D. The presenting symptoms were prostatism (10), urinary retention (6), gross hematuria (2), lumbago (2) and pathologic bone fracture (1). Of the 21 patients, 15 (71%,) patients had elevated enzymatic acid phosphatase levels and 7 patients had distant metastases. Stage D prostatic carcinoma was subclassified as stage D
