【摘要】 目的:比较不同KM小鼠封闭群部分生物学特性的差异。方法:测量小鼠身长,尾长,尾椎节数及长度。结果:本中心KM小鼠与河北医科大学KM小鼠相比:身长无差异。20周龄、30周龄尾长差异显著;本中心小鼠尾骨节数分别为26,而河北医科大学KM小鼠尾骨为28节。结论:由于长期的封闭饲养,本中心KM小鼠与其它KM小鼠存在差异:尾较长,30周龄长2cm。更多还原

【Abstract】 Aim To compare difference of biological character of closed colony KM mice. Methods Body length and tail length of the mice were measured at 3,20 and 30 weeks. Tail bone were numbered. Results These were difference in tail length at 20 and 30 weeks,no difference in body length. The number of tail bone is different:Henan 26,Hebei 28. Conclusion Because of long closed breeding,KM mice of Henan Medical University are difference at tail length and the number of tail bone from other KM mice. The tail is more longer.更多还原
