BACKGROUND AND PURPOSE Visual field defects sometimes occur after temporal resection surgery. Our purpose was to evaluate the correlation between visual field defects caused by temporal lobe resection and the degree of resection of the Meyer loop, as assessed by diffusion tensor tractography. MATERIALS AND METHODS We examined 14 patients who underwent(More)
The symptoms following sinus and vein occlusion observed in patients and experimental animals display a considerable variability that so far remains largely unexplained. In a rat cortical vein occlusion model using a photochemical thrombotic technique, we examined changes in the cerebral venous flow pattern by fluorescence angiography and regional cerebral(More)
A rat model of cortical vein occlusion by the photochemical thrombotic technique was used to evaluate whether monitoring the change in the local cerebral blood flow (LCBF) could predict brain damage after cortical vein occlusion. The cortical vein occlusion was attained by using the photochemical thrombotic technique, and the sequential LCBF was measured by(More)
Vascular permeability factor (VPF)/vascular endothelial growth factor (VEGF) is unique in its ability to promote vascular permeability and endothelial cell growth, and its role in tumor development has received considerable attention. In this report, we describe the elevation of VPF/VEGF transcript expression in human hepatocellular carcinoma. Surgical(More)
OBJECTIVE The complement system is thought to play a major role in initiating some of the inflammatory events that occur during reperfusion injury. The aim of this study was to assess the effects of C1 esterase inhibitor (C1-INH) on ischemic injury in the rat model of middle cerebral artery suture occlusion and reperfusion. METHODS Thirty-six male Wistar(More)
We evaluated the alexia and agraphia of three patients with different lesions using Japanese kanji (morphograms) and kana (phonograms) and made a lesion-to-symptom analysis. Patient 1 (pure alexia for both kanji and kana and minor agraphia for kanji after a fusiform lesion) made more paragraphic errors for kanji, whereas patient 2 (alexia with agraphia for(More)
To evaluate the role of the sub-cortical white matter and cortical areas of the supramarginal gyrus in short-term memory impairment (shortened digit or letter span) and repetition difficulty, four patients with conduction aphasia and impaired short-term memory and two patients with only short-term memory impairment were given digit span, letter span, speech(More)
Inflammatory bowel disease (IBD) is an important etiologic factor in the development of colorectal cancer. However, the mechanism underlying carcinogenesis through chronic inflammation is still unknown. Activation-induced cytidine deaminase (AID) is induced by the inflammation and involved in various human carcinogenesis via its mutagenic activity. In the(More)
