The male and female rats (n=15, respectively) were randomly divided into three groups, and Fluoro-Ruby, a fluorescent tracer, was stereotaxically injected into the ventromedial hypothalamus, bed nucleus of the stria terminalis and posterodorsal nucleus of the amygdale by iontophoresis, respectively.Five days later, the rats were perfused, and the sections containing SDN-POA region and site of injection were cut on a freezing microtome.the sections were viewed to assess extent of tracer deposition in the injection site and to reveal the EGFP or Fluoro-Ruby fluorescence in SDN-POA under fluorescence microscope.

雌、雄性大鼠(各15只)随机各分成3组，分别通过离子电渗法将示踪剂Fluoro-Ruby注入下丘脑腹内侧核（VMH、终纹床核、杏仁核后背侧核。5 d后，灌流固定鼠脑，做冷冻冠状切片，荧光显微镜下确定示踪剂注入位置，并观察SDN-POA绿色荧光和Fluoro-Ruby标记荧光。

RESULTS:(1)Electrical stimulation of ventral septal area caused a significant increase in firing rate of warm-sensitive neurons in the preoptic area of the anterior hypothalamus.

In situ hybridization and immunocytochemical studies indicated that treatment with 17beta -estradiol increased the number of aromatase-immunoreactive cells and their immunoreactivities, especially in the preoptic area of the hypothalamus, where the density of the aromatase-immunoreactive cells was 2.6 folds higher than the control group. Results indicated that brain aromatase may be involved in the feminization induced by 17beta -estradiol of the grey mullet.

原位杂交和免疫细胞化学定位表明：雌二醇处理组鲻鱼脑内芳香化酶阳性细胞数量和反应强度均提高，尤其在下丘脑视前区，芳香化酶阳性细胞的分布密度为对照组的2.6倍，说明17beta-雌二醇诱导幼鲻雌性化可能与脑芳香化酶的表达有关。

Psychogenic ED may not be simply a functional disease;the hypothalamus may be involved in the pathophysiology of the problem.

心理性ED是否仅仅是单纯的功能性疾病，在中枢神经系统是否存在潜在的致病因素及其病理生理机制尚

MSG could insult the functions and structures of specific brain areas of adult mice through blood-brain barrier. The ability of discrimination learning in Y-maze was affected markedly, especially in 4. 0g/kg MSG group, meanwhile, dark pyknotic and loss of neurons were shown in arcuate nucleus of hypothalamus, but not in hippocampus. Consistent changes occured in mitochondrial membrane protein bound 〓 by 〓-fluoresent probe, i.

MSG可以透过成年小鼠血脑屏障产生神经毒性作用。4.0g/kg MSG对小鼠空间分辨学习能力的损伤程度较2.5g/kg MSG更为明显，同时下丘脑弓状核神经元出现核固缩及神经元数目明显减少，相同处理未引起海马神经元的明显变化。

The colon temperatures were measured by a thermistor and the cytosolic free calcium concentration ([Ca2+]i) in dissociated brain cells was measured by Fura 2-AM. The results demonstrated that the pyretic action of egtazic acid (0.6 μmol, icv) was markedly inhibited by DEX (5 mg/kg,iv), but DEX (60-120 μmol/L) did′t affect [Ca2+]i in dissociated hypothalamus cells. Actinomycin D, which interferes with gene transcription (3 nmol, icv), completely abolished the antipyretic action of DEX on egtazic acid-induced fever.

结果发现：脑室灌注乙二醇双(2-氨基乙醚)四乙酸(0.6 nmol)引起家兔结肠温度明显升高，静脉注射地塞米松(5 mg/kg)显著抑制家兔乙二醇双(2-氨基乙醚)四乙酸性发热，地塞米松(60-120 μmol/L)并不影响下丘脑细胞内[Ca2+]i，而事先脑室灌注抑制基因转录的放线菌素D(3 nmol)则完全取消了地塞米松对乙二醇双(2-氨基乙醚)四乙酸性发热的解热作用。
