The authors report a case of recurrent subarachnoid hemorrhage (SAH) after complete occlusion of an intracranial aneurysm. It is known that regrowth of an aneurysm after the complete clipping is a rare event. For detection of recurrence, however, it may be necessary to follow up with the patient regularly after the initial operation for intracranial aneurysms, because re-rupture of an aneurysm can cause a fatal result, and the cumulative risk of a recurrent SAH is thought to be not low over time.

Salmonella infection can cause an asymptomatic intestinal carrier state or clinical diseases such as enterocolitis presenting abdominal pain, fever, vomiting, or diarrhea. Salmonella usually invades Peyer's patch of terminal ileum or ascending colon. Sepsis is not common and acute renal failure secondary to rhabdomyolysis is rare. The causes of rhabdomyolysis are trauma, excessive exercise, alcohol, seizure, metabolic abnormality, and infection. Infections account for less than 5% of the reported causes of rhabdomyolysis and resulting acute renal failure. The mechanisms underlying rhabdomyolysis due to infection are direct muscle invasion, toxin production, and nonspecific effects that can occur with infections such as fever, dehydration, acidosis, and electrolyte imbalance. We report a case of sepsis and acute renal failure secondary to rhabdomyolysis associated with Salmonella infection.

PURPOSE: Central lucency of pelvic phleboliths is frequently observed on plain pelvic radiographs. When it is also present on noncontrast helical CT images, pelvic phleboliths may be easily diagnosed, with no suspicion of distal ureteral calculi. The objective of this study was to determine the frequency with which this phenome-non is seen on plain radiographs and noncontrast helical CT images. MATERIALS AND METHODS: During a recent two-year period we identified 70 patients with renal colic who under-went both abdomino-pelvic radiography and noncontrast helical CT scanning. Radiographs were obtained at 70 -85 kVp and 30 -40 mA; CT scans were preformed within one month of plain radiography with parameters of 120 kVp, 200 -220 mA, 5-mm collimation, and pitch of 1 -1.6, and using soft tissue and bone window settings. With regared to the central lucency of pelvic phleboliths, as seen on both on radiographs and CT im-ages, two experienced radiologists reached a consensus. RESULTS: Among the 70 patients, a total of 150 pelvic phleboliths was found. In all cases except one, pelvic radi-ography and noncontrast helical CT revealed the same number of phleboliths. The exception was a case in which one of two phleboliths demonstrated by CT was not seen on radiographs. Pelvic radiography revealed central lucency in 95 of these 150 phleboliths (63%), but noncontrast helical CT failed to depict a hypodense center in any phlebolith. CONCLUSION: Central lucency of pelvic phleboliths, as frequently seen on plain pelvic radiographs, was not revealed by routine noncontrast helical CT in any patient.The presence or absence of central lucency on these CT images cannot, therefore, be used to differentiate phleboliths from distal ureteral calculi.

The purpose of this study was to investigate the relationship of nose profile with respect to skeletodental pattern, by measured and analyzed statistically the lateral cephalograms of 95 females (13 to 30 years old ). The results were summerized as follows; 1. The antero-posterior factors of the nose - nasofrontal angle, nasofacial angle, and dorsal length / ala length ratio were different among the malocclusion groups 2. There were no significant correlation between the vertical nose factors and the skeletal factors 3. The Class I groups had a straight nose profile; the Class II groups had a convex profile ; the Class III groups had a concave profile.

The purpose of this study was to compare shear bonding strengths and debonding patterns of the ceramic brackets attached on the crystal which were grown on the enamel surface of a tooth with different concentrations of lithium sulphate-contained polyacrylic acid in different application times. Four kinds of concentrations of mixed solutions were made and applied to the enamel surface on extracted human premolars. The solutions were made by adding 0.3M or 0.6M of lithium sulfate to 50% or 65% of polyacrylic acid with 0.3M sulfuric acid. The solutions were applied for 30 or 60 seconds. After bonding, a universal testing machine was used to measure the shear bond strength, and then observations were made of debonding patterns through the stereoscope. And the enamel surface was observed through the scanning electron microscope to examine the pattern of crystal growth and debonding. The results were as follows: 1, Shear bond strength in the enamel surface treated with 50% polyacrylic acid was higher than that with 65% polyacrylic acid. 2. There were no statistical differences in shear bond strength according to concentration of lithium sulfate and application time of solutions. 3. Enamel surface was almost free of resin debris after debonding. 4. Enamel surface treated with 50% polyacrylic acid showed higher density of crystal growth than that with 65% polyacrylic acid under scanning electron microscope.

The purpose of this study was to investigate osteonectin expression patterns in cleft palatecompare to normal palate rats. We used 4 pregnant rats, and beta-aminoproprionitrile was oral dose to rat according to lg/kg body weight at gestation days 13 to induce cleft palate. Total 6 fetus was got with cleft formed, then 3 fetus was used for immunohistostain and 3 fetus was used for western blot analysis. Expression patterns of osteonectin in mesenchymal cells of cleft palate was more dilute to mesenchymal cells of normal palate with immnunohistostain, and width and length of band of maxilla in cleft palate was more thin than maxilla of normal palate with western blot study.

Cleft palate has been studied with epidemiologic and molecular methods, and many etiologic factors have been examined closely. Among the research methods, biologic molecule research has been the most important method for cleft palate formation study. The TGF-beta played an important role in cell migration, epithelial-mesenchymal transdifferentiation, extracellular matrix synthesis and deposition. But there was not much research on the correlation cleft palate induced by beta-aminonitroproprionitrile(BAPN) and TGF-beta expression. The purpose of the present study was to examine how TGF-beta is expressed in cleft palate rats. 4 Timed-pregnant Sprague-Dawley rats were obtained on the 10th gestation day. On the 13th day of gestation, BAPN-monofumarate salts ((C3H6N2)2.C4H4O4) were individually, orally administered to 3 pregnant rats at a ratio of 1g/kg body weight. And 4 pregnant rats were sacrificed on day 20 post coitus (p.c.). The TGF-beta expression in the cleft formed rats fetuses showed the following patterns : 1. Osteoblast and mesenchymal cells of the cleft palate rats were of low expression compared with those of the control rats. 2. The cleft palate rats didn't show any difference in the TGF-beta expression of osteocyte from the control rats. 3. In western blot analysis, the thickness of band of TGF-beta in the cleft palate rats was thinner and more diluted than that of the control rats.
