    Notes: Abstract We examined immunohistochemically 123 autopsy brains from patients aged between 30 to 59, who died as a result of malignant neoplasms. Using antiserum to amyloid β protein (Aβ), we found that cerebral Aβ deposits began in the subjects' fifth decade; its prevalence was 0%, 9.8% and 21.5% in the fourth, fifth and sixth decades, respectively. The major form of Aβ deposition was diffuse-type plaques, although one third of the brains with Aβ deposition showed amyloid angiopathy. Subpial Aβ deposition is frequently associated with amyloid angiopathy. The prevalence of cerebral Aβ deposits was about two times higher in the patients who had received brain radiation therapy (27.8%) compared to non-radiated patients (14.8%). Amyloid angiopathy was much more prominent (P 〈 0.05) with radiation therapy (22.2%) than without (8.0%). We found that cerebral Aβ deposition is dependent on aging, even in patients with malignant tumors and at beginning in their forties, and that brain radiation therapy is a possible risk factor of Aβ deposition, especially in the form of amyloid angiopathy.

    Notes: Adhesive resins with high adhesive strength and high heat resistance have been studied in developing a novel iron-core printed circuit board with high mechanical strength and high heat radiation capability. A reticular pattern formed on the surface of an adhesive resin composed of nitrile rubber, phenolic resin and epoxy resin. It caused blisters in the plating or reduced the heat resistance of the printed board. This pattern was formed as a result of phase separation of epoxy resin or phenolic resin from the nitrile rubber. Using a high-molecular-weight epoxy resin led to high adhesive strength and high heat resistance, without phase separation. The relationships between the composition of adhesive resins and their characteristics were discussed on the basis of the state of their surface after being roughened by chemical etching. © 1996 John Wiley & Sons, Inc.
