摘要:
Improved process for preparing 1,2-diacyl-3-glycerylphosphorylcholines, wherein the diacyl groups are, different or the same, a residue of a saturated or unsaturated fatty acid, particularly one of the acyl groups being a residue of a highly unsaturated fatty acid or being a residue of a saturated or unsaturated fatty acid labelled with an isotope, which comprises acylating a glyceryl-phosphorylcholine or monoacyl derivative thereof or the salt thereof with an acylating agent (e.g. 1-acylimidazole or 4-acyl-3-phenyl-1,2,4-oxadiazol-5-one) in the presence of a catalyst (e.g. an alkali salt of a nitrogen-containing 5-membered heterocyclic compound or sodium oxide).
摘要:
A therapeutic agent for treating consciousness disorder and perception and movement which comprises as an essential active ingredient a phosphatidic acid derivative selected from a phosphatidylcholine, a phosphatidic acid and a phosphatidylethanolamine in admixture with a conventional carrier. Said agent is administered to the patient suffered from consciousness disorder and perception and movement disorder, particularly the post-traumatic syndrome of the head injury and the sequelae of apoplexy or whiplash injury in oral or parenteral route, preferably in an intravenous route.

摘要:
A fuel supply apparatus is provided for an intake manifold and a fuel injection system that can be easily and reliably mounted together by a mounting structure, even when the intake manifold has an integrated design in which air intake branches curve steeply upward from a downward side to an upstream side. With this fuel supply apparatus, the fuel injection system is mounted with coupling bolts on the top surface of the outer wall of the downstream portion of the intake manifold. The threads of the bolts engage internal threaded bores in the fuel injection system. The heads of the bolts are disposed on a reverse side of a top surface of an outer wall of the intake manifold, with internal threaded bores of the fuel injection system being disposed on a side of the top surface of the outer wall of the intake manifold.
