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(shí)驗(yàn)動(dòng)物。前人研究結(jié)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。
