Objective To investigate the effect of 8 Hz infrasound on the expression of brain derived neurotrophic factor in the rat hippocampus.

目的研究频率为8 Hz，声压级分别为90，100和130 dB的次声作用对大鼠海马脑源性神经营养因子表达水平的影响。

The results were as follows the change of vitamin C content was a "trial apex"-shape curve, higher in young fruit,incrustation and maturation stages, lower in other periods; the total acid content was the highest in young fruit, after that, it decreased rapidly, maintained lower level, and reached lowest when the fruit matured; the total content of soluble sugar inosculated with the fruit development, it was high when the fruit development was quick, and low when the fruit development was slow; before 59 d after anthesis, the reducing sugar content was high in the total content of soluble sugar and after that ,the nonreducing sugar content was high; before 45 d after anthesis, free amino acid content was obviously correlated with protein content, and they inosculated with the fruit development;4559 d after anthesis, free amino acid content increased quickly, and protein content decreased gradually, this was also the most shaping period of the embryo and endosperm.

结果表明，Vc含量呈&三峰&型曲线，幼果时、硬核后和成熟时较高，其他时期较低；有机酸含量以幼果期最高，以后迅速下降并维持较低水平，果实成熟时含量最低；可溶性总糖含量与果实发育状况基本相吻合，果实发育速度快时含量较高，慢时较低；在谢花后59 d以前，可溶性糖以还原糖为主，之后以非还原糖为主；游离氨基酸和蛋白质含量，在谢花后45 d以前两者呈高度相关，且与果实生长速度相吻合，谢花后4559 d是胚和胚乳的主要形成期，此期游离氨基酸含量迅速增加，蛋白质含量持续下降。西北林学院学报21卷第5期张传来等金光杏梅果实发育期间主要营养成分动态变化研究

Objective To survey the relationship between nutrimental condition and the levels of serum lipids and lipoprotein.

目的 探讨营养状况与血脂及载脂蛋白水平的关系。

Under light, middle and heavy degradation, with the increase of degradation, the vegetative ramet capacity of the clones increased, while their reproductive ramet capacity decreased. A typical landscape of "black soil beach" appeared in grassland with extreme degradation; the growth of the clones was in a lowest level.

Development of brown rice food is of signality for increasing food supply of China and improving national nutrition and health status.

糙米食品开发对于增加我国食物供应总量和提高国民营养保健水平意义重大。

Data were analyzed from photographs from optical microscopy and Computer Image Analysis.Results:Gene expression level of bcl-2mRNA (numeric density and concentration of bcl-2 immunopositive neurons) in layer Ⅲ of the ipsilateral visual cortex area 17 and the laminas receiving ipsilateral geniculate input from the strabismic and deprived eyes are significantly lower than the input from the untreated eyes.

MS1和MD1组幼猫实验眼同侧视皮质17区Ⅳ层及同侧外侧膝状体Al层神经元在视觉发育敏感期内，由于长期的斜视及形觉剥夺效应以致功能低下，对Bcl-2调节的敏感性降低，以及对NTs的营养保护及上调Bcl-2 mRNA表达水平应答能力降低，在双眼竞争的神经元发育及突触连接中处于劣势，使对侧眼形成优势循环。

At the same time, people are demanding that food should not only be touchable, but also be nutritional.

同时，经济的发展与生活水平的提高，人们对于食品的要求正逐步由温饱型向感官满足型转变，继而向营养保健型。
