大马哈鱼是我国特有的鱼类资源，我们将由其精巢中提取出的精氨酸核蛋白进行了毒理学实验研究。该精氨酸核蛋白大鼠急性毒性经口ＬＤ５０为大于１０ｇ／ｋｇ；蓄积系数＞５，为弱蓄积物质；小鼠骨髓微核试验，小鼠睾丸染色体畸变实验及Ａｍｅｓ实验均为阴性，认为该物质在食用上是比较安全的物质。
Salmon is a unique fish resource in our country. We have conducted toxicological experiments on arginine nucleoprotein extracted from its testis. The arginine nucleoprotein rat acute toxicity oral LD50 is greater than 10g / kg; accumulation coefficient> 5, is a weak accumulation of material; mouse bone marrow micronucleus test, mouse testicular chromosome aberration test and Ames test were negative, that The substance is safer to eat.
