Patent DE-4000084-A1 (DE)
Inventor: WIEBECKE DIETER
IPC: A61P35/00
Filed: 1990-01-03
Abstract: A pharmaceutical preparation of ET18-OCH3 for intravenous administration containing a lipophilic oil-in-water emulsion can be used to administer high doses of the pharmacon ET18-OCH3 without side effects. The lipophilic emulsions in the preparation contain ordinary lipophilic particles of the size of chylomicrons. The active substance and the lipophilic emulsion in the pharmaceutical preparation are usually administered intravenously at the same time. However, the oil-in-water emulsion and the active substance can also be administered separately or at intervals. For this reason, a pharmaceutical preparation is described in which the active substance ET18-OCH3 and the lipophilic emulsion exist as a combination preparation. Also described is the use of ET18-OCH3 and the lipophilic emulsion to manufacture drugs which have an antiproliferative effect and are used to suppress immunological reactions and to treat tumours, as well as to treat multiple sclerosis and autoimmune diseases.

Patent DE-4007560-A1 (DE)
Inventor: CHEUNG NELSON
IPC: B29C65/72
Filed: 1990-03-09
Abstract: Overlapping portions 11, 15 of a thermoplastic strap 12 positioned about a package or article are joined together by a weld joint 14 (e.g. friction, adhesive or thermowelding) and the joint includes means (26, 28) for increasing the peel separation resistance of portions 11, 15 of the joint. This prevents peel separation and so results in a joint strength that approaches the tensile strength of the strap material (11, 15) or weldment (14). The means for increasing peel strength may be wire, tape or spot weldments (additional welding) or achieved by deforming the strap such that the weldment joint 14 is in an angular orientation (Fig 5) or by having portion 11 radially outwardly or convexly curved relative to the other portion. <IMAGE>
