实验动物垫料毒性安全评价进展

垫料（Laboratory animal bedding）是影响实验动物健康与实验结果的重要因素之一。目前使用的垫料主要有刨（shaving）、锯末（sawdust）、玉米芯（corncob）、再生纸（recycled-paper）、秸秆（straws）、果壳（hulls）及其他纤维类材料（plant fiber andother）等。本文从实验动物垫料原材料毒性、抽提物毒性、以及垫料对实验动物生长繁殖的影响几个方面进行了分析，认为杨木和玉米芯是比较理想的垫料原料。

Progress on Toxicity Evaluation for Laboratory Animal Bedding

Bedding is one of the important factors which influences animal health and quality of animal experiment. Beddings of the current usage primarily consist of shavings of wood, corncob, recycled-paper, straws, hulls and other fiber materials. This paper reviews the toxicity of the bedding materials, extraction, and the bedding influences on laboratory animal growth and breeding. In fact, the white poplar and corncob are ideal bedding materials.
