将伯氏疟原虫感染小鼠，当其血原虫密度大于３０－００ ％ ，置病鼠于－ ２０ ℃低温冰箱保存。经不同时间后，迅速解冻，心脏取血，经腹腔内接种健康小鼠，以观察原虫复苏成功率。结果表明：低温保存５０ ～１００ ｄ 和１０１～１５５ ｄ，病鼠复苏成功率分别为３３－３３ ％ 和２０－００ ％ 。提示该法仍不适为一种简便可行，行之有效的低温保存方法。 Plasmodium berghei was infected in mice, when the density of the protozoa was more than 30-00%, the mice were sacrificed and stored at -20 ℃ in a refrigerator. After a different time, thawed rapidly and blood was taken from the heart. Healthy mice were inoculated intraperitoneally to observe the success rate of parasite recovery. The results showed that the success rates of resuscitation in diseased mice were 33-33% and 20-00% respectively after being stored for 50-100d and 101-155d. Suggesting that the law is still not suitable for a simple and feasible, effective method of cryogenic preservation.
