    Notes: Summary The level of cerebrospinal fluid (CSF) protein is elevated in diseases and disease models that are associated with circulating immune complexes such as serum sickness. Circulatory immune complexes are known to deposit in the basal lamina of fenestrated capillaries and may, as a result, affect both capillary bed and parenchymal function. Since the brain has both fenestrated and unfenestrated capillaries and immune complexes deposit to a varying extent in the fenestrated capillaries in chronic serum sickness, cerebral capillary permeability to protein may be altered in some brain areas and lead to the elevation of CSF proteins. In addition various other cerebrovascular and metabolic functions may also be affected by this condition. In this study either radio-iodinated serum albumin (RISA) or 2-[14C]deoxyglucose (14C-2DG) was intravenously injected into control Wistar rats and Wistar rats with chronic serum sickness; subsequently the tissue levels of radioactivity were measured by quantitative autoradiography in 4 brain areas with fenestrated capillaries and 11 brain areas with unfenestrated capillaries. The 2-min distribution of RISA, which demarcates the volume of circulating plasma in perfused microvessels and is generally proportional to local plasma flow, was the same in control and experimental rats. The passage of RISA from blood into brain over 30 min was negligible in both groups; thus cerebral capillary permeability to albumin was not detectably increased in any of these 15 brain areas by chronic serum sickness. The rate of local cerebral glucose utilization, an indicator of local metabolic and neural activity, was calculated from the 14C-2DG data and was virtually identical in control and experimental rats. These results suggest that chronic serum sickness at this stage has little effect on capillary bed permeability and parenchymal function in most, if not all, brain areas.

    Notes: Abstract. The MR features of a 57-year-old man with multiple tendinous xanthomas are reported. The lesions of the peroneus longus tendons and the Achilles tendons showed diffuse reticulated pattern, which is the typical MR finding of tendinous xanthomas. However, the lesions of the patellar tendons showed no diffuse pattern and contained focal regions of high signal intensity on T 1-weighted images suggesting the deposition of triglycerides. The regions showed high signal intensity on T 2-weighted images and moderate enhancement on contrast-enhanced T 1-weighted images suggesting the presence of associated inflammation.

    Notes: The combustion of H2 gas with N2O gas was investigated in order to rapidly heat substrate to a high temperature. A transient thermometry with a 100-nm-thick Cr film as a temperature sensor formed on quartz substrate was used to measure temperature change at the surface. The gas combustion was induced by heating a W filament. It propagated with a velocity higher than 100 m/s throughout a chamber for an initial total gas pressure of 500 Torr ([H2]/[N2O]=1). The sample surface is heated to 800 °C for an initial substrate temperature at 300 °C. The full heating time width at half maximum was 4.5 ms. This letter shows a possibility of millisecond-order rapid thermal treatment. © 1996 American Institute of Physics.
