Title: Souble phospkorylated glucan
Inventor: DALUZIO NICHOLAS R
IPC: C08B37/00
Filed: 1986-08-13
Granted: 1990-11-22
Abstract: A new class of soluble phosphorylated glucans is described as well as the process for making the same. According to a preferred embodiment, the soluble phosphorylated glucan is derived from the yeast Saccharomyces cerevisiae. The soluble phosphorylated glucans are useful for prophylactic and therapeutic applications against neoplastic, bacteria, viral, fungal and parasitic diseases. Additionally, they may be administered as a non-toxic adjuvant, in combination with chemotherapy. The soluble phosphorylated glucans are also useful for stimulating macrophage cells, either in vivo or in vitro, to produce a cytotoxic/cyctostatic factor effective against cancer cells.

Abstract: The dividing voltage drum of an electrophotographic recording mode comprises independent basic layers formed by dividing a conductive basic layer of a cylinder shape drum by the number of the steps; insulating layers formed between the independent basic layers to insulate the independent basic layers; an optical conductive layer deposited over the whole surface except a part of the basic layers and insulating layers with a constant depth; and electrodes formed over the part on which the optical conductive layer is not deposited, for applying a voltage to each independent basic layer.
