the previous studies suggested that the auditory threshold of fmmu albino guinea pigs was lower significantly than that of pigment ones, the anoxia tolerance of fmmu albino guinea pigs was better than that of pigment ones, their immunological function was weaker than that of pigment ones 目的:fmmu白化豚鼠是從普通花色豚鼠突變種中選育而成的新品系封閉群實驗動物。前人研究結果表明fmmu白化豚鼠的聽覺閾值明顯低于花色豚鼠,缺氧耐受性優(yōu)于花色豚鼠,免疫功能低于花色豚鼠。
