氯五氟乙烷(碳氟化合物115)作为加压包装食品的一种助喷剂,其急性毒性和蓄积性毒性都低。本实验目的是以血中氯五氟乙烷浓度作指标观察氯五氟乙烷吸入和经口摄入之间的关系。用狗作以下三个实验:①一次吸入10%(V/V)氯五氟乙烷10分钟;②摄入(经导管注入)含有8%(W/W)氯五氟乙烷的奶油调料;
Chloropentafluoroethane (Fluorocarbon 115), as a spray-aid for pressurized packaged foods, has low acute toxicity and accumulative toxicity. The purpose of this experiment is the blood chloropentafluoroethane concentration as an indicator of chloropentafluoroethane inhalation and the relationship between oral intake. Dogs were used for the following three experiments: (1) inhalation of 10% (V / V) chloropentafluoroethane for 10 minutes; (2) ingestion of (via catheterization) creamy dressing containing 8% (W / W) chloropentafluoroethane ;
