The authors performed prospectively the transcranial Doppler monitoring of bilateral anterior and middle cerebral arteries in 15 patients with ruptured cerebral aneurysm. The entry criteria for the study were confined to the patients who were admitted within 3 days after bleeding and had clinical grades of I, II, or III. The mean frequency shifts of bilateral anterior and middle cerebral arteries were increased immediately after ictus and showed continous further elevation between the 3rd and 8th rupture days. After that, they normalized slowly. The increase of frequency shift preceded clinical ischemic symptoms and an early steep increase of frequency shift was correlated to a high chance for suffering delayed ischemic deficits. The thick clots in subarachnoid cisterns shown on CT scans taken within the third rupture day were correlated well to the severe increase of frequency shifts. The aggressive treatment was done on asymptomatic patients who showed relatively rapid increase of frequency shifts, and they had shown no or trasient mild ischemic symptoms.

BACKGROUND: The purpose of this study was to discover ways to screen urine culture specimens through Gram stains, urine stick analyses and microscopic examinations for the laboratory cost saving. METHODS: One hundred and fifty-eight urine specimens for culture were included. Fifty uL of urine were inoculated onto one well each of 10-well slide, dried on the hot plate, and Gram-stained. The results combined with routine urinalyses including urine nitrite and leukocyte esterase, and pyuria, were compared with the routine culture results. RESULTS: The screening of bacteriuria by Gram stains, urinalyses and microscopic examinations revealed the high sensitivity (91.9%) and negative predictive value(95.5%) with cost saving of 41.8% of inoculating media. Not considering the Gram stains, the screening revealed 83.8% sensitivity and 92.5% negative predictive value, even if the cost saving of inoculating media were as high as 50.1%. CONCLUSION: It was demonstrated that it was sensitive and economic and produced rapid preliminary results to screen bacteriuria by the Gram stains combined with urinalyses and microscopic examinations.

Fibrous Dysplasia of bone is a relatively rare condition characterized by fibrous tissue replacement of skeleton. It may be monostotic (confined to one bone) or polyostotic (situated in many bones). Here, six cases of fibrous dysplasia and, among them, typical three groups classified by Lichtenstein & Jaffe were experienced and treated during past one year. Three cases were monostotic lesion, which is more common, and usually mild and asymptomatic. And another three cases were polyostotic lesion, two of which were not associated with extraskeletal symptoms, and one case was associated with extraskeletal symptoms, so called Albrights disease. These six cases of fibrous dysplasia are reported with a review of the literatures.

OBJECTIVE: To investigate the role of ERK and PPAR gamma on the TGF-beta1 induced human endometrial stromal cell decidualization in vitro. METHOD: Endometrial stromal cells are cultured under the following condition: DMEM/F12 (10% FBS, 1 nM E2 and 100 nM P4). TGF-beta1 (5 ng/ml), Rosiglitazone (50 nM), and PD98059 (20 microgram) were added according to experimental purposes. Trypan-Blue and hematocytometer were utilized to count cell number. Enzyme-linked immunosorbent assay (ELISA) and western blotting were utilized to detect proteins. RESULT: TGF-beta1 inhibited proliferation of cultured human endometrial stromal cells and induced expression of PGE2 and prolactin. This effect was mediated by Smad and ERK activation. Administration of rosiglitazone, PPAR gamma agonist, prevented TGF-beta1 effect on cell proliferation. Furthermore, Rosiglitazone inhibited TGF-beta1 induced activation of ERK, consequently reduced PGE2 and prolactin production. CONCLUSION: TGF-beta1 induced decidualization of endometrial stromal cell through Smad and ERK phosphorylation. PPAR gamma acts as a negative regulator of human endometrial cell decidualization in vitro.

Subaortic left ventricular aneurysm is a rare, mostly congenital condition, and occurs as a result of a defect in the alveolar fibrosa between the mitral and aortic annuli. Clinically, most subaortic left ventricular aneurysms are asymptomatic, but some of them cause arrhythmia, chest pain, and even sudden cardiac death. We report an autopsy case of sudden cardiac death due to subaortic left ventricular aneurysm in a 38-year-old male sailor.
