PURPOSE: To evaluate the role of CT in the diagnosis of bowel and mesenteric injury we studied the CT findings and its usefulness in patients of abdominal trauma. MATERIALS AND METHODS: CT scans of 27 patients who were confirmed to have bowel and/or mesenteric injury due to abdominal trauma were analyzed retrospectively. Of these 27 patients 15 had bowel injury only and 12 had both bowel and mesenteric injury. CT findings analysed were bowel wall thickening, presence or absence of highly attenuated bowel wall, sentinel clot, mesenteric infiltration, peritoneal fluid collection and free intraabdominal air in cases with bowel injury only and with both bowel and mesenteric injury respectively. Ten patients had other accompanying abdominal injuries, such as liver, spleen, pancreas, kidney, bladder injuries, intraperitoneal abscess or retroperitoneal hemorrhage. RESULTS: Findings observed were bowel wall thickening in 23 cases(85%), peritoneal fluid collection in 21 (78%), highly attenuated bowel wall in 19(70%), mesenteric infiltration in 17(63%), free intraperitoneal air in 10 (37%) and sentinel clot in 7(26%). Pneumoperioneum were observed in 10 of 24 patients(41.7%) having bowel perforation. Two cases did not show any CT findings suggesting bowel and/or mesenteric injury. There was no significant difference in the prevalence of the CT findings between the patient group with bowel injury only and the patient group with both bowel and meseneric injury. CONCLUSION: CT scan is a useful tool in evaluating the degree and extent of bowel and/or mesenteric injury as well as in planning the patient's management.

The purpose of this study was to investigate the characteristics or the potassium channels existing in the rat urinary bladders. Smooth muscle strips of rat detrusor urinae were examined by isometric myography. Relaxation responses of detrusor muscle strips to the three potassium channel openers pinacidil, a cyanoguanidine derivative, BRL 38227, a benzopyran derivative and RP 52891, a tertrahydrothiopyran derivative were examined. The potassium channel openers reduced the basal tone, and the rank order of potency was RP 52891>pincidil>BRL 38227. Procaine, an inhibitor of the voltage-sensitive potassium channel tended to increase the basal tone, but it did not affect the relaxant effects of the calcium-activated potassium channel opener did not antagonize the relaxant effects, but it reduced the Emax of RP 52891 and BRL 38227. Glibenclamide, an inhibitor of the ATP-sensitive potassium channel, antagonized the relaxant effects of pinacidil, RP 52891 and BRL 38227 reducing the Emax of RP 52891 and BRl 38227. Galanin which inhibits secretion of insulin through opening the ATP-sensitive potassium channels in pancreatic β-cells rather increased the basal tone of the isolated detrusor strips. These results suggest that the urinary bladder of the rat has mainly the ATP-sensitive, glibenclamide sensitive potassium channel, which is a different type from that in the pancreatic β-islet cells.

Renal cell carcinoma, intimately associated with a sarcomatous component, is a rare malignant renal tumor. There is disagreement whether these represent true sarcomas or are sarcomatoid metaplasia. Therefore, this sarcomatous component is at times still a troublesome problem for pathologists. In March, 1986, we experienced a case of renal cell carcinoma associated with rhabdomyosarcomatous component in 47 year-old woman who had a rapidly enlarged, palpable abdominal mass. Grossly, a spherical renal cell carcinoma, 17x14x10 cm, in upper and middle portions of the right kidney showed extension through the renal capsule into the perirenal fat. Area of myxoid change was evident in the reanl cell carcinoma, with extensive hemorrhagic necrosis. Microscopically, in the myxoid area, there was malignant spindle cell proliferation in which many rhabdomyoblasts showing distinct cross striation could be demonstrated. This rhabdomyosarcomatous component intermixed with renal cell carcinoma of clear cell type could be also identified in the focal area.

Among total 108 cases of biopsy-proven fibroadenomas of the breast, which obtained from the files of the Asan Medical Center during one year period from October 1998 to September 1999, 23 cases cytologically diagnosed as high risk group were reviewed to retrieve the mis-leading factors. Initial cytologic diagnoses of 23 cases were proliferative breast lesion with atypia(high risk) in 21 cases(91.3%) and papillary neoplasm in 2 cases(8.7%). When we reanalysed 23 cases by Masood scoring system, they were classified as one non-proliferative breast lesion(4.3%), 16 proliferative breast lesions without atypia (69.6%), and 6 proliferative breast lesions with atypia(26.1%). None were subject to the category of carcinoma. Cytologic features leading to the overdiagnosis of high grade epithelial lesions were as follows; cellular dissociation without nuclear atypia, nuclear pleomorphism, anisonucleosis, and occasional macronucleoli without nuclear enlargement, lack of myxoid stroma, and few naked stromal cells. To avoid cytologic overdiagnosis of fibroadenoma, mild to moderate nuclear pleomorphism without nuclear enlargement, and cellular dissociation without nuclear atypia should not be regarded as criteria of high risk group.
