Abstract: A herapathite has a capillary crystal form in which its iodine atoms are oriented in a major axis direction of the capillary crystal form. The herapathite obtained is expressed by a chemical formula, xC 20 H 24 N 2 O 2 ·yH 2 SO 4 ·zHl 3 , in which a ratio of a number of the sulfuric acid molecules (y) with respect to a number of the iodine atoms (3z), i.e., (y/3z), is less than 0.5. The production process includes a reaction step, a first separating step, a recrystallizing step and a second separating step. A solvent used in the recrystallizing step is at least one of water and alcohol. A mixing weight ratio of water with respect to alcohol of the solvent is more than 50/50 or less than 10/90. The herapathite does not degrade even after it is heated up to 130 °C, and it is applicable to an automobile light shielding glass which should show a high transparency when a voltage is applied thereto.

Abstract: Procédés et appareils de préparation de nouvelles compositions de lipoprotéines oxydées. Des peroxydes sont capables de produire des radicaux libres, lesquels à leurs tours, peuvent oxyder des lipoprotéines in vitro ou in vivo. On a découvert que le peroxyde d'hydrogène, seul ou conjointement avec certaines enzymes tels que la peroxydase ou la lipoxydase peuvent oxyder les lipoprotéines. Les lipoprotéines peroxydées de faible densité constituent la composition préférée. Les lipoprotéines oxydées présentent un effet cytotoxique auquel les cellules malades sont plus sensibles que les cellules en bonne santé. Ainsi, les lipoprotéines oxydées peuvent être utiles dans le traitement de nombreux états pathologiques. L'ampleur de la peroxydation des lipoprotéines est mesurée par obtention d'un spectre de RMN au C-13 de la solution de lipoprotéines oxydées.
