Abstract: A mixture obtained by mixing ascorbic acid powder with arginine powder in a weight ratio (ascorbic acid/arginine) of 1/5 to 20, especially 1/5 to 1/4; and a supplement such as a nutrient preparation and a health-care food containing the mixture. Mixing of arginine powder and ascorbic acid powder in the weight ratios eliminates stringent taste specific to arginine and alleviates stringent feeling in the stomach (heartburn, nausea or vomiting) after oral intake thereof. The mixture prevents also peroxidative injuries of cells caused by an administration of a great amount of arginine alone. Further, mixing of arginine powder with ascorbic acid powder prevents browning of the mixture after long-term storage.

Abstract: In a vehicle having a cabin with an ingress-and-egress opening portion on its side provided between a front-wheel axle and a rear-wheel axle, there are provided plural passenger seats including a driver seat on a floor panel, a support member to support its seat cushion and seat back in such a manner that the seat cushion is selectively held in sitting state of a substantially horizontal position or in stored state of a substantially upright position, whereas the seat back is selectively held in first-use state of a substantially upright position or in second-use state of a substantially horizontal position, and seat rails to support the passenger seat movably in a longitudinal direction. An effective use of passenger seats can be improved, and an utility space in the cabin can be enlarged at need.

Abstract: A mixture obtained by mixing ascorbic acid powder with arginine powder in a weight ratio (ascorbic acid/arginine) of ⅕ to 20, especially ⅕ to ¼; and a supplement such as a nutrient preparation and a health-care food containing the mixture. Mixing of arginine powder and ascorbic acid powder in the weight ratios eliminates stringent taste specific to arginine and alleviates stringent feeling in the stomach (heartburn, nausea or vomiting) after oral intake thereof. The mixture prevents also peroxidative injuries of cells caused by an administration of a great amount of arginine alone. Further, mixing of arginine powder with ascorbic acid powder prevents browning of the mixture after long-term storage.

Abstract: Enol form .delta.-lactone of diketogulonic acid (2,3,6-trihydroxy-4-oxo-2-hexen-5-olide; R-345), which is the enediol type oxidation product of ascorbic acid, and/or its sodium salt, potassium salt or calcium salt has activities of markedly reducing the toxicity of Adriamycin, reducing radiation injury, reducing liver damage induced by an organic halogen compound, and further accelerating recovery from a high blood sugar level in Alloxan-induced diabetes, using vitanim E in combination.
