Histamine deficiency markedly potentiated the acquisition of learning in cued and contextual fear conditioning in the HDCKO mice,but had no effect on cued and contextual fear extinction.However,histamine deficiency potentiated the inhibitory role of morphine withdrawal in cued fear extinction.Consistent with the behavioral results,morphine withdrawal decreased ERK phosphorylation in the amygdala and mPFC but not in the hippocampus of WT and HDCKO mice,and ERK might not be phosphorylad in the amygdale and mPFC of HDCKO mice after the 4th training of cued fear extinction.

但HDCKO小鼠增强了吗啡戒断对线索恐惧记忆消除的抑制作用，与行为学实验结果相一致是，，吗啡戒断能明显降低WT和HDCKO小鼠在线索恐惧记忆消除第4次训练后杏仁核和mPFC脑区的ERK磷酸化水平，但对海马脑区的ERK磷酸化没有作用；HDCKO小鼠在线索恐惧记忆消除训练的第4次训练后杏仁核、mPFC脑区的ERK蛋白没有明显磷酸化激活。

The microstructure of hardened layer and formation mechanism were investigated.The microstructure of hardened layer consist of the completely hardened region and the transition region.The completely hardening region is composed of fine acicular martensites,residual austenites and a few dot-like carbonides.From surface to bottom in the hardened layer,the microstructure varies from fine to coar...

结果表明：采用适当的磨削参数可满足该钢所要求的淬火温度，进而获得适宜的淬硬层显微硬度和强化层深度；磨削淬火层由完全硬化区和过渡区组成；完全硬化区主要由细小针状马氏体组成，从表面到里层，组织形貌呈现&细→粗→细&的变化规律，其形成机理是热-力耦合作用影响磨削淬火过程中的奥氏体晶粒大小及其位错密度，并将直接影响转变后的马氏体组织形貌。

The actual rock blasting tests are touched in failure effects of near-field, seismic effects in far-field, and irreversible deformation regions. The latest similarity research results in underground blasting, shallow-buried blasting (throwing and directional blastings) are also presented.

The purpose of the present study was to investigate the role of central arginine vasopressin in corticotropin releasing hormone-induced fever in the rat. Guide cannulae were inserted into the third ventricle and placed over the ventral septal area. The content of arginine vasopressin in the VSA of the brain was determined by radioimmunoassay. Colon temperature was monitored in lightly restrained rats by insertion of a catheter-mounted thermistor probe 5 cm in the rectum.
