ABSTRACT
Objective To conduct the preliminary toxicology tests and evaluate the preservation effect on a new specimen preservation solution in order to provide scientific basis for its application security. Methods Twenty-four New Zealand white rabbits were randomly di-vided into the normal saline group, the formalin preservation group,the mixture group,and the new preservation solution group. Recorded the irritation of different solution on the skin,eye of rabbits,the effect of liver sample preservation in different solution,and the evaporation rate of these solution. And to find a set of preservative solution which is more suitable for preservation of specimens and can reduce the cost. Results The new preservation solution is stimulus on rabbit skin and eye,and it is stronger than the formaldehyde group. Compared with the other three groups,the mixture group has the best preservation effect, and the new preservation solution group has a better preservation effect than the formalin preservation solution group. Conclusion The 1∶1 mixture solution of the new preservation solution and formaldehyde is more suitable preservation solution and it can reduce the costs.
