Isolated angiitis of the central nervous system is a rare clinicopathologic entity characterized by vasculitis restricted to the vessels of central nervous system without other apparent systemic vasculitis. It manifests headache, higher cortical dysfunction. focal neurologic dysfunction and cranial nerve palsies. We experienced a case of isolated angiitis of the central nervous system in 6 year-old girl who was admitted to out unit because of headache, hemiparesis and altered consciousness. The laboratory test for blood, urine, and cerebrospinal fluid are all within normal ranges. There was no evidence of systemic vasculitis. The contrast enhanced brain CT scan showed low densities along the left cerebellar hemisphere and posterior aspect of temporal lobe without enhancement, and left lateral internal carotid angiogram showed poorly contrast filling along the territory of left posterior cerebral artery due to narrowing or ischemic changes of the vessels. Axial T2WI (TR/TE, 2190/80) of magnetic resonance imaging showed multiple scattered high signal intensities at left pons with cerebellar hemisphere and diffuse high signal intensity along the left occipital lobe with enlarged surrounding gyral patterns, and axial T1WI(TR/TE, 665/25) showed intense gyral pattern contrast enhancement along the left occipital lobe. Steroid was tried with apparent benefit. We report a case of isolated angiitis of central nervous system with review of literature.

This study was performed ta evaluate difference of colposcopic findings between carcinoma in situ and microinvasive carcinoma. From August l, 1988 through November 30,1989, the conixation was undertaken in 138 patients. We compeied colposcpic findings with hiatologic diagnoiis on 1656 seetions. Comparison between the microinvasive carcinorna and the carcinoma in situ groups showed a significant higher incidence of large exoeervtcal lesion size(>3/2 33.9% vs. 1.2%), circumscribved location around external cervical os.(75.0% vs, 51.2%), combined abnormal colposcopic findings(19.6/a vs. 3. 7%) and deep endocervical involvement( >lcm : 23,2% vs. 7. 3%). (P<0.01) Granular area was showed 11% incidence of the worst histologic diagnosis.

Bile is the major route of cholesterol excretion from the body. It is concentrated in the gallbladder, and often results in supersaturation of cholesterol. The high levels of cholesterol in gallbladder bile has clinical implications with respect to cholesterol gallstone formation and cholesterolosis of the gallbladder wall. Gallbladder epithelial cells (GBEC) are exposed to high cholesterol concentrations on their apical surfaces. Therefore, GBEC are uniquely positioned to play an important role in modulating biliary cholesterol concentrations. Recently, it has been documented that the key-transporter for polarized cholesterol and phospholipid efflux in GBEC is ATP-binding cassette transporter A1 (ABCA1) and Liver X receptor (LXR) and retinoid X receptor (RXR) in the nucleus of GBEC have a role that regulates ABCA1 expression. In addition, GBEC synthesize apolipoprotein A-I and E as cholesterol acceptors. These results indicate that GBEC has a perfect system for reverse cholesterol transport. We introduce the roles and mechanisms of ABCA1, scavenger receptor class B-I, LXR and RXR related to reverse cholesterol transport in GBEC with a review of our study experience and related literature.
