胭脂鱼(Myxocyprinus asiaticus)精子冷冻保存及对超微结构的影响

open access: yesHaiyang yu huzhao
胭脂鱼(Myxocyprinus asiaticus)是亚洲特有的淡水珍稀鱼类,但由于人类活动和生态环境的变化,胭脂鱼数量急剧减少,研究其精子冷冻保存技术及建立精子冷冻保存库,对种质资源的保护和遗传育种具有重要意义。选取健康的雄性胭脂鱼,经人工催产后获得成熟精子,首先对4种精子稀释液种类(D-17、D-15、D-20、人工精浆A)、4种抗冻剂种类(DMSO、GLY、MeOH、PG)及4种DMSO抗冻剂浓度(6%、8%、10%、12%)进行筛选,其次选取筛选后冷冻效果最好的冻精与鲜精做受精实验 ...

益生菌对菲律宾蛤仔体内全氟辛酸免疫毒性的调节作用研究

open access: yesHaiyang yu huzhao
全氟辛酸(perfluorooctanic acid, PFOA)是一种具有多系统毒性的新污染物,对双壳贝类可产生一定的免疫毒性效应,损害机体的正常免疫功能。益生菌作为一种安全无毒的食品级制剂,已被应用于水产养殖行业,用以提高水生生物的免疫防御能力。然而,益生菌对贝类中新污染物所引发的生物毒性是否有消减作用,目前尚不可知。据前期研究,新污染物PFOA在水生生物尤其贝类中存在较高的蓄积量,具有潜在的生态和健康风险。因此,探索经济贝类中益生菌对PFOA免疫毒性的消减作用具有重要意义 ...
