本文研究目的是为了评价小鼠和兔吸入苯蒸气后对胚胎和胎仔发育的影响。实验用工业苯。动物选自未做过实验的CF—I小鼠和新锡兰种白兔。置铁笼内,在可控制温度、湿度和每12小时光、黑交替的房间内饲养,动物饲以供实验用的食物和自来水,除染毒时间外均自由进食。实验前,先让动物至少适应2～3周。小鼠以观察到阴栓、兔以自然交配那天作为妊娠的零天算起。将妊娠6～15天的35和37只小鼠与妊娠6～18天的兔每组20只,分为实验组和对照组,分别暴露于容积为4.3米~3的Rochester型染毒室内,进行动式染
The purpose of this study was to evaluate the effects of inhalation of benzene vapor on embryonic and fetal development in mice and rabbits. Experimental use of industrial benzene. The animals were selected from non-experimental CF-I mice and New Zealand white rabbits. Set inside the cage, temperature and humidity can be controlled and every 12 hours light and black alternating room feeding, animals fed for experimental use of food and tap water, in addition to exposure time are free to eat. Before the experiment, let the animals adapt for at least 2 to 3 weeks. Mice were observed with a thrombus and rabbits were counted as zero days of pregnancy on the day of natural mating. 35 and 37 mice from 6 to 15 days of gestation and 20 from 6 to 18 days from gestation each group were divided into experimental group and control group and were respectively exposed to a Rochester-type infection chamber with a volume of 4.3-3. For dynamic dyeing
