mesencephalic 中文意思是什麼

Our previous studies confirmed that the central pathway of trigeminal proprioceptive sensation consists of four orders of neurons, and neurons from the first - to the fourth - order are located, respectively, in the mesencephalic trigeminal nucleus ( vme ), the dorsomedial part of the subnucleus oralis of the spinal trigeminal nucleus and its adjacent reticular formation ( vodm - lrf ), the " zone - shaped area " [ including the caudolateral part of the supratrigeminal nucleus ( vsup - cl ), the dorsomedial part of the principal sensory trigeminal nucleus ( vpdm ), the area ventral to the motor trigeminal nucleus ( avm ) and the area dorsal to the superior olivary nucleus ( ado ) ] and the contralateral ventral posteromedial nucleus ( vpm ) of the thalamus. because the pathway is a novel one, there has been little systematic morphological data available so far regarding the neurotransmitters involved in this pathway

該通路中第二、三級神經元所在地分別是三叉神經脊束核吻側亞核背內側區及其鄰接的網狀結構（ dorsomedialpartofthesubnucleusoralisofthespinaltrigeminalnucleusanditsadjacentreticularformation ， vodm - lrf ）和帶狀區[包括背側的三叉上核尾外側部（ caudolateralpartofthesupratrigeminalnucleus ， vsup - cl ）和感覺主核背內側部（ dorsomedialpartoftheprincipalsensorytrigeminalnucleus ， vpdm ）及腹側的兩個分別位於三叉神經運動核腹側和上橄欖核背側的暫命名為avm （ areaventraltothemotortrigeminalnucleus ）和ado （ areadorsaltothesuperiorolivarynucleus ）的兩個小核團] 。

The result indicated that the nadph - dstained neurons and fibers were found in discrete regions throughout the snake brain, such as cerebral hemisphere, supraoptic nucleus, paraventricular nucleus, subcommissural organ, medial longitudinal fasciculus, periventricular grey, locus coeruleus and mesencephalic reticular formation

結果表明：陽性反應主要位於腦的大腦半球、視上核、室旁核、聯合下器官、內側縱束、室旁灰質、藍斑以及網狀結構等區域，比較討論了與其他脊椎動物的異同。

Upregulation of neurod mrna expression might underlie elf - emf effect on promoting mesencephalic progenitors to a neuronal phenotype

Emfs的促神經前體細胞神經元向分化的效應與其在轉錄水平上調neurodmrna的效應有關。

In addition, the immediate elf - emf exposure might induce cell cycle arrest, thus also contributing to its stimulating effect of neurogenesis from mesencephalic neural progenitors

此外， elf emfs抑制中腦神經前體細胞增殖，加速神經前體細胞退出細胞分裂周期，可能也是elf

The elf - emfs had no impact on neurite outgrowth. it was concluded that elf - emf, with the advantage of economy, convenience, as well as easy control, might be an effective method ex vivo to manipulate neural progenitors differentiation in stem - cell therapy. the possible mechanism of the elf - emfs effects on neurogenesis of mesencephalic progenitors was further explored

Emfs的此效應具有頻率特異性，場強也是影響因素； 10 20 40hz （ 8mt ） emfs還可增加衍生於中腦神經前體細胞的th陽性細胞數；但各頻率emf對神經突的延伸均無作用。

In the subsequently serial differentiation studies, the findings were as followed : ( l ) among observed chemicals, only 50 pg / ml il - 1 was found to promote neuron - oriented differentiation of mesencephalic neural progenitors while 100 ng / ml gdnf, 10 ng / ml cntf and 10 - 5 mm gastrodin indicated a inhibitory effect, the rest chemicals, 10 - 5mm puerarin, or 10 - 5mm arctiin, or 10 - 5mm ginsenoside rgl, had no effect on neuronal differentiation. these findings confirmed that fate decision of newborn rat mesencephalic progenitors could be manipulated by environmental signals

施加elf emf （ 5hz 8mt ）后，小劑量cntf的促進效應增強，特別是emf還可使大劑量cntf抑制神經元向分化的效應轉變為促進神經元向分化； emf可抑制小劑量il一1q促進神經元分化的作用，但不影響大劑量il ? lq的誘導結果。

Only il - 1 could be used to predispose mesencephalic neural progenitors to enrich cell yield in a neuronal phenotype before cell transplantation. ( 2 ) the effects of cntf and il - 1 on neural progenitor differentiation were dose - related. ( 3 ) coeffects of elf - emf and cytokines were neither synergized nor antagonized, implying a potential role of organism emf during cns development

顯示emf與cntf 、 il一1a的共同效應不是簡單的脅同或拮抗，提示emf可能與細胞因子共同影u向應著神經系統的發育。

By the analysis of cell cycle disturbution and the examination of mashl, neurod and notchl mrna expression in proliferating or differentiating neural progenitors, the findings implied an important role of neurod in controlling the neuronal fate commitment in mesencephalic neural progenitors from newborn rats

增殖及分化期的新生大鼠中腦神經前體細胞neurod 、中義摘要mashl和notchl基因表達的測定結果表明， neurod基因在新生大鼠中腦神經前體細胞神經元向分化中發揮關鍵作用。
