Title: Infusion containing n-highly unsaturated-acyl-alpha-amino acid derivative
Inventor: HIBINO HIDEHIKO
IPC: A61K31/195
Filed: 1987-03-20
Abstract: PURPOSE:To provide an infusion containing an N-highly unsaturated- acyl-alpha-amino acid derivative. CONSTITUTION:The objective infusion contains an N-highly unsaturated- acyl-alpha-amino acid derivative which is a reaction product of a highly unsaturated fatty acid (e.g. gamma-linoleic acid, dihomo-gamma-linoleic acid, arachidonic acid, eicosapentaenoic acid or docosahexaenoic acid) with an alpha-amino acid. The alpha-amino acid is e.g. aspartic acid or glutamic acid and an oligopeptide having C-terminal can be used as the amino acid. The infusion can be prepared only by dispersing glycerol and an N-highly unsaturated-acyl-alpha-amino acid derivative in distilled water for injection without using intensive emulsifying agent or high-pressure emulsifier. If necessary, vitamins and minerals can be easily added to the infusion. Since the infusion can be supplied through mouth, vein or intestine, it can be utilized as an infusion for the improvement of nutrient balance or as a post-operative nutrient or remedy.

Further, electrode 41 for contact detection can detect a contact by detecting voltage generated in the piezoelectric element when the tip end of the optical fiber comes into contact with a recording medium. After detecting the contact, the voltage application quantity of the electrodes 21 and 23 is changed so that the distance between the optical fiber edge and the recording medium can be a prescribed value, and the optical fiber edge is set to a fixed focus position.
