"Community newspapers certainly are not immune to the economic downturn that is affecting all businesses, but, as the primary and sometimes sole provider of local news in a community, they remain strong and viable," NNA president John Stevenson said in the article.

"社区报纸肯定不会完全免于影响到一切行业的经济下滑，但是，作为在一个社区当地新闻主要，有时候唯一的提供者，他们依然保持强劲、有效。"NNA主席John Stevenson在文章中称。

NO could be synthezied for maintaining the resting cerebrovascular tonus in normoal condition and was involved in the vasodilatation mechanism under hypoxia. In these 2 aspects, the NO effects could be inhibited by L-NNA.

在静息状态时，NO有维持离体基底动脉血管条基态张力的作用；低氧时，NO在脑血管的舒张反应中也占有重要地位，两种作用都可以被L-NNA抑制。

L-Arg, L-NNA and aminoguanidine had no effect on the iNOS mRNA expression.

而L-Arg、NOS抑制剂L-NNA及氨基胍均不影响胰腺组织iNOS基因水平的表达。

In fundic strips, ghrelin and GHRP-6 could decrease the on-response induced relaxation and increase off-response induced contraction of the muscle, with the effect of Ghrelin obviously stronger than that of GHRP-6.L-NNA could increase the effects of Ghrelin and GHRP-6-induced muscle contraction, and L-AA could decrease their effects.

在胃底部，Ghrelin和GHRP-6可使开电刺激诱导的平滑肌舒张活动减弱，断电刺激诱导的肌条收缩活动增强，且Ghrelin作用明显强于GHRP-6.L-NNA可显著增强Ghrelin和GHRP-6的促平滑肌收缩效应，但L-AA可显著减弱该作用。

In pure cultured neuron, the inhibitory effect of 0.5mmol/L L-NNA on theincrease of LDH leaking after exposure of H/R and SIN-1 had also no statistical significance, but it could inhibit significantly the above index in mixedly cultured cerebral cortex neuron and glia.

在单纯培养神经细胞中0.5mmol／LL－NNA对H／R＋SIN－1导致的LDH漏出率增加仍无显著抑制作用，但可显著抑制H／R引起的混合培养的神经细胞和神经胶质细胞的LDH漏出率。

After administration of L-N〓-nitro-Arginine, a specific antagonist of NOS, it was found that the basal and stimulated NO release of blood vessels (aorta, internal carotid, renal and mensenteric artery) was decreased further. The increase of coronary blood flow stimulated by Ach was also reduced further, while the platelet aggregation degree and erythrocyte aggregation index increased significantly. Pathological examination indicated that aortic endothelium was destroyed, the blood vessels in cerebral, cardiac and renal tissues were hypertrophied further and some were almost occluded. The above fin dings resulted in SHR feeded with L-NNA having high incidence of stroke rate and high degree of renal cirrhosis when compared to control SHR. The infarct and hemorrhagic focuci in cerebral tissues, infarct focuci in cardiac tissues, atrophy and hyalinedegeneration of renal glomeruli and degeneration even necrosis of renal tubuli in renal tissues were al so found. The increase ratio of brain and heart to body weight and decrease ratio of kidney to body wei ght further demonstrated that the cerebral, cardiac and renal injuries were aggravated.

在上述结果的基础上进一步给予SHR NOS特异性拮抗剂左旋亚硝基精氨酸后，血管(胸主、颈内、肾及肠系膜动脉)NO基础释放及激动剂刺激释放进一步减少，Ach刺激冠脉流量的增加和胸主动脉内膜NOS活性也进一步减少，血小板聚集程度及红细胞聚集指数显著上升，病理切片显示胸主动脉内皮细胞破坏明显，脑心肾组织内的血管进一步增厚甚至几乎阻塞，导致饲L-NNA的SHR缺血性及出血性脑卒中发生率显著高于对照SHR，脑体重比显著升高；心肌内出现明显的缺血梗塞疤痕灶，心体重比显著升高；肾小球明显萎缩、玻璃样变性，肾小管也变性甚至坏死，使肾硬化程度显著增加呈颗粒性固缩肾，肾体重比也显著减少。

Methods 25 adult female rats were divided into the control group, low dorsage group of PNS, medium dorsage group of PNS, high dorsage group of PNS and L-NNA group after the spinal cord hemisected. Corresponding dosage of PNS was fed to the rats in the three groups of PNS every day.

25只成年雌性大鼠在施行脊髓半横断术后，被分为对照组、三七总皂甙低剂量组、三七总皂甙中剂量组、三七总皂甙高剂量组和L-NNA组。

The abnormal release of DA from ischemic striatums were significantly inhibited by L-NNA.

结果：大鼠半球缺血30分钟时，纹体DA的释放形成高峰，其后逐渐下降，但都高于缺血前释放量。L-NNA能明显抑制缺血时纹体DA的不正常释放。

However,all of the DA releases during 60,90,120min global ischemia were significantly higher than that before ischemia. The abnormal release of DA from ischemic striatums were significantly inhibited by L-NNA.

结果：大鼠半球缺血30分钟时，纹体DA的释放形成高峰，其后逐渐下降，但都高于缺血前释放量。L-NNA能明显抑制缺血时纹体 DA的不正常释放。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
