Effect of protein and lipid in rice on starch physicochemical characteristics, difference between the region of non-chalkiness and chalkiness of rice, dynamic variation of cell structure and CaM distribution on rice spike were expounded in this study. It was found that protein and lipid in rice had important effect on starch gelatinization, there were distinct differences between the region of non-chalkiness and chalkiness of rice, vascular bundle system in rice spike was changed during grain filling, difference quality of different position of rice spike was more distinct in dense spike rice for more powerful vascular bundle system, the development of rice seeds was corresponded to pericarp development, difference quality of different position of rice spike was also related to transport function of rachilla besides activity of "source", and calmodulin relative activity was closely related to grain filling velocity and enginery properties.
通过实验发现:稻米中蛋白质、脂肪对淀粉的糊化过程有着较大的影响;精米的非垩白与垩白部位以及心白与腹白部位之间在蛋白质、氨基酸含量及组成方面存在着明显差异:水稻穗部大维管束面积以及主穗轴维管束数目在灌浆过程中存在明显的动态变化趋势;密穗型水稻强势粒的维管组织比散穗型水稻发达,致使其强、弱势粒维管组织差异明显加大;果皮的发育与籽粒发育状况是相适应的:强势粒和弱势粒在灌浆生理方面的差异,不仅表现在籽粒本身的&库活性&上,而且也与其着生小穗轴的输导功能有关;CaM相对活性与水稻灌浆速率、机能特征间存在着密切联系。

For confirmation of this ancient legend and found out the sexual improvement compounds the testosterone and NO in serum of mice were measured,the weight of sexual organs of mices was detected and the sex behaviour of mice was observed.The testosterone and NO concentration in serum of mice as indicator for screening some improving sexual compounds from Chinese chives was builted.1、The preliminary experiment of Chinese chives confirm sexual improvement functionThe sexual improvement function experiments of Chinese chives comparing with herba epimedii,herba cynomorii and radices morindae which were acknowledged as chinese herbals having sexual improvement function were carried out.The result was showed that the Chinese chives was confirmed having sexual improvement function,though its efficacy was less than herba epimedii,herba cynomorii and radices morindae.
为了证实古代医学认为韭菜的壮阳功能,揭示韭菜起温肾壮阳作用的化学物质基础,开发其功能性物质成分,本实验首先应用韭菜酒精初提液对小鼠睾酮、NO含量、性器官、性行为等指标的测定,验证韭菜是否具有改善性功能作用,然后以小鼠睾酮、NO含量等为指标对韭菜中的壮阳物质进行逐步分离和改善性功能作用筛选,以鉴定出几种改善性功能的物质。1、韭菜改善性功能的验证将韭菜与淫羊藿、琐阳、巴戟天三种有温肾补养功能的中草药进行比较,发现韭菜改善性功能作用不如淫羊藿、琐阳、巴戟天壮阳中草药的效果明显,但是韭菜还是具有显著的改善性功能作用的(P<0.001)。

During the surgery, the lesion was found to be a solid tumor. A surgical wedge biopsy was done and purulent dark yellow fluid was drained from the center of the mass. Histologically, there was a solid pattern of rhabdoid and anaplastic round or oval cells haphazardly arranged with poor differentiation. Immunohistochemical staining was positive for vimentin, a mesenchymal marker; the reticulin staining was consistent with carcinoma.
我们实施了手术切片及肿瘤中心脓状物引流,病理组织学上,我们发现了不规则或未分化的横纹状、圆形及椭圆形细胞;免疫组织染色上,细胞广泛的对非上皮标记vimentin呈阳性反应、且其reticulin染色呈现出腺癌的形式;肉瘤及腺癌的特色皆可在切片中看到,所以我们的诊断是类肉瘤性线癌。

Among the 45 neurons generating phasic firing, 8 (17.78﹪) neurons could still be induced phasic firing after treatment with 1×10-2 μg/mL SVHRP and 37 (82.22﹪) neurons had no responses to the stimulation. The AP firing of neurons was dramatically different after treatment with SVHRP (P<0.01, n=45). Among the 7 repetitive firing neurons, all of them could only generate 1 or 0 AP instead of repetitive firing when SVHRP was applied. The number of APs was 14.57±1.00 and 0.57±0.20 before and after SVHRP treatment (P<0.01, n=7). The AP rheobase was (75.10±8.99) pA and (119.85± 12.73) pA before and after 1 × 10-4 μg/mL SVHRP application, respectively (P<0.01,n=8). The AP threshold was increased from (-41.17±2.15) mV to (-32.40±1.48) mV after 1×10-4 μg/mL SVHRP treatment (P<0.01,n=8). The peak amplitude of AP was (68.49±2.33) mV for the neurons before treatment with 1×10-4 μg/mL SVHRP and (54.71±0.81)mV after treatment (P<0.01, n=8). These results showed that SVHRP could decrease the AP firing frequency, increase the AP rheobase and threshold, but decrease the AP peak amplitude of hippocampal neurons.
在产生位相放电的45个细胞中,有8个细胞在SVHRP处理后仍可以诱发出位相放电(占17.78﹪);37个细胞在SVHRP处理后无法诱导出位相放电(占82.22﹪),SVHRP处理后动作电位的产生与处理前相比,有显著差异(P<0.01,n=45);在产生重复放电的7个细胞中,在1×10-2μg/mL SVHRP作用后均不能再次诱发出重复放电,而是产生一个动作电位或不再产生动作电位,药物处理前产生的动作电位个数为14.57±1.00,SVHRP处理后产生动作电位的个数为0.57±0.20,二者之间有显著性差异(P<0.01,n=7)。1×10-4 μg/mLSVHRP处理后,诱发动作电位产生的基强度由(75.10±8.99)pA增加到(119.85±12.73)pA(P<0.01,n=8);阈电位由(-41.17±2.15)mV升至(-32.40±1.48)mV(P<0.01,n=8);动作电位峰值由(68.49±2.33)mV下降至(54.71±0.81)mV(P<0.01,n=8)。

These Thoughts so oppress'd my Mind, that I began to give over my Enterprize, and having haled my Boat into a little Creek on the Shore, I stept out, and sat me down upon a little rising bit of Ground, very pensive and anxious, between Fear and Desire about my Voyage; when as I was musing, I could perceive that the Tide was turn'd, and the Flood come on, upon which my going was for so many Hours impracticable; upon this presently it occurr'd to me, that I should go up to the highest Piece of Ground I could find, and observe, if I could, how the Sets of the Tide, or Currents lay, when the Flood came in, that I might judge whether if I was driven one way out, I might not expect to be driven another way home, with the same Rapidness of the Currents: This Thought was no sooner in my Head, but I cast my Eye upon a little Hill, which sufficiently over-look'd the Sea both ways, and from whence I had a clear view of the Currents, or Sets of the Tide, and which way I was to guide my self in my Return; here I found, that as the Current of the Ebb set out close by the South Point of the Island; so the Current of the Flood set in close by the Shore of the North Side, and that I had nothing to do but to keep to the North of the Island in my Return, and I should do well enough.
我思想压力很大,不得不考虑放弃原定的计划。我把小船拉进沿岸的一条小河里,自己迈步上岸,在一块小小的高地上坐下来沉思。我心情忧郁,心绪不宁。我害怕死,又想前去探个究竟。正当我沉思默想之际,只见潮流起了变化,潮水开始上涨。这样,我一时肯定走不成了。这时,我忽然想到,应该找一个最高的地方,上去观察一下潮水上涨时那两股急流的流向,从中我可以作出判断,万一我被一股急流冲入大海,是否有可能被另一股急流冲回来。我刚想到这一层,就看见附近有一座小山;从山上可以看到左右两边的海面,并对两股急流的流向可以一目了然,从而可以确定我回来时应走哪一个方向。到了山上,我发现那退潮的急流是沿着小岛的南部往外流的,而那涨潮的急流是沿着小岛的北部往里流的。这样,我回来时,小舟只要沿着北部行驶,自然就可以被涨潮的急流带回来。
