"At present there is great freedom in the way laboratory animals can be used," comments John Yu, president of the Chinese Society of Laboratory Animal Sciences. Yu says openly that there is no rigorous control over such things as the number of animals used in experiments, whether they are destroyed painlessly afterwards, or whether they are subjected to further experiments before they have recovered.
「目前使用實驗動物非常自由」，實驗動物學會理事長余玉林直言，對使用動物數量的控制、實驗過的動物是否給以安樂死、動物生理未恢復前，是否又重複給予實驗等，並未嚴格管制。
