魚卵巣の成熟とパントテン酸との関係 Relation between the Maturation of Fish Ovary and Pantothenic Acid 手島, 新一 37856 TESHIMA, Shinichi 1000070041704 金澤, 昭夫 11133 KANAZAWA, Akio 1000070041697 柏田, 研一 105785 KASHIWADA, Kenichi 660 A research on the possible relationships between the pantothenic acid and the fish ovary maturation is treated in this paper. Using ayu and loach as the test fish, the maturity grades of the ovary were estimated by ovaryweight per cent and per total body. The pantothenic acid content per unit weight, of fish ovary varies in accordance with the degree of maturity ; the highest content is to be seen when the maturity degree has reached about 4%. Generally the amount of free formed pantothenic acid exceeds that of the conjugated one ; a sudden increase of the total pantothenic acid, especially the conjugated pantothenic acid, is to be brought forth at the maturation in full swing. It is suggested that the gradual accumulation of pantothenic acid is motivated by the maturation of the ovary, and that it is to be changed into the conjugated form at full maturation, playing a part in the metabolism of the ovary. departmental bulletin paper 鹿児島大学 Kagoshima University 1966-12-15 VoR application/pdf 鹿児島大学水産学部紀要 15 8 12 Memoirs of Faculty of Fisheries Kagoshima University 0453087X AN00040498 https://ir.kagoshima-u.ac.jp/record/12786/files/AN00040498_v15_p8-12.pdf http://hdl.handle.net/10232/13829 https://ir.kagoshima-u.ac.jp/records/12786 jpn open access
