作者认为评定马拉硫磷对各种生物的作用,应以灵敏的生物学的和神经机能的方法进行试验,方能作出正确判断。[对大鼠的毒性]用重量100～300 g的雌性大鼠,分别以急性经口投与LD_(50)的1/20和1/40量(相当于75和38mg/kg体重),混于标准基础饲料中喂养90天,各取大鼠10只(另不投药10只,以资对照),在隔音、避光室中,于大鼠额部和枕部插入银电极,测定脑电图(EEG)的变化,同时还于腓肠肌
The authors believe that the assessment of the effect of malathion on various organisms should be tested in a sensitive biological and neurological way to be able to make the right judgments. [Toxicity to rats] Female rats weighing 100 to 300 g were each orally administered with 1/20 and 1/40 (corresponding to 75 and 38 mg / kg body weight) of LD 50 each The standard basal diet was fed for 90 days, 10 rats were taken from each other (another 10 animals were not dosed for reference).
