RESULTSdiabetic rats showed typical symptoms involving elevated serum glucose and weight loss (2)The rats in DM+VaD group reacted slower and made more error numbers in Y-maze than the rats in VaD group did, with a prolonged total reacting time in a whole day.(3)More neurons with serious damages, such as edema, ischemia or pyknosis could be found in DM+VaD group than in VaD group. More disarrangement of cone neurons, obvious glia proliferation, and more neuron apoptosis were found in CA area of hippocampus. CONCLUSIONS (1)2-VO in STZ-induced diabetic rats succeeded in establishing VaD animal models.(2) The cognitive dysfunction induced by VaD rats had been deteriorated by diabetes mellitus.(3)Morphology evidences proved that diabetes mellitus aggravated brain damages induced by VaD.PART II Effect of diabetes mellitus on the cholinergic nervous systemin CA1 area of hippocampus of VaDOBJECTIVE To estimate the role of cholinergic nervous system in hippocampus during the process of cognitive dysfunction aggravated by diabetes mellitus in DM+VaD group.

为得出推论，你首先需要估计这一误差的概率

It is usual to estimate the error variance in the existing method of second order character.

现行的二阶特征算法通常是对方差的估计，算法存在共同的局限性，即假定样本中不含有显著误差，并且服从正态分布。

No degrees of freedom left to estimate the error variance when the data of this design are analyzed, so the standard ANOVA can t be used.

然而在分析这类数据时因为无多余的自由度可用于估计误差方差，因而不能采用标准的方差分析法。
