Results:(1) FSN can inhibit secondary joints swelling and multi-arthritis evidently, improve the whole condition of rats; at the same time, it can also lighten the synovial inflammation and hyperplasia of lesion joints distinctly, and prevent the joint cartilage and bone from destruction; the collective efficiency of FSN is better than TWP.(2) FSN can raise AA rats low LTT of spleen to normal nearly, remedy the disorder of Th / Ts and Thl / Th2 cells balance in peripheral blood, restrain exorbitant TNF- a ? IL-1 produced by PM O , thereof exert anti-inflammatory and immunoregulation effect.(3) Inside the lesion joints, FSN can depress abnormal hyper-expression of TNF- a mRNA and NF-kB in synovial tissues, as well as advance the expression of Caspase-3 (a proteolytic enzyme of apoptosis), reduce synovial immflamination and proliferation.(4) FSN can lower the expression of VEGF in synovial tissue,reduce neogenetic veins, so inhibit the growth of pannus tissue and the damage of cartilage and bone by that.(5) The above effect of FSN are in proportion to its dosage.Conclusions: FSN has inhibitory effects on symptom and condition of experimental RA, which is better than TWP as a whole.

结果：(1)FSN有明显的抗炎作用，可显著抑制AA大鼠足跖肿胀与多关节炎，改善大鼠的全身情况，同时明显减轻病变关节滑膜炎症与增生，防止关节软骨及骨质的破坏，其综合作用优于TWP；(2)FSN还能使AA大鼠低下的脾LTT恢复至接近正常，纠正外周血中T细胞亚群Th／Ts及Th1／Th2平衡紊乱，抑制大鼠PHφ过高的TNF-α、IL-1分泌，而发挥抗炎和免疫调节作用；(3)在病变关节局部，FSN能显著抑制AA大鼠滑膜细胞异常增高的TNF-αmRNA的表达，降低滑膜组织中NF-kB表达，并增加凋亡蛋白酶Caspase-3表达，从而抑制滑膜的炎症与增殖；(4)FSN还可下调滑膜组织中VEGF表达，减少血管新生，由此抑制血管翳的形成及其对软骨和软骨下骨的侵蚀；(5)FSN的上述作用皆呈现一定的量效依赖关系，高剂量组作用优于低剂量组。

At present it is widely accepted that the damages of the nasal turbinate bones and mucus caused by Bordetella bronchiseptica laid the foundation for the invasion toxigenic Pasteurella multocida. The mixture of Bordetella bronchiseptica and toxigenic Pasteurella multocida, together with some other factors, is the main cause of natural AR.

经过多年研究，现在大多数学者认为，支气管败血波氏杆菌能引起一定程度的鼻粘膜和鼻甲骨损害，但这些病变的严重后果是为正常猪鼻腔不能定居的产毒素多杀巴氏杆菌建立感染铺平道路，Bb和T+Pm的混合感染加上非传染因素交织在一起，是在自然条件下临床型AR的发生原因。

To avoid the increase, you will need to order soon. We will honor current pricing for all Volvo Penta orders placed prior to 3 pm EST on Thursday July 31, 2008. You should know that individual prices may rise more sharply than 4.1%, so if you know you need parts, it might be prudent to make purchases before the increase and avoid disappointment later.

从8月1日起，我司或将随之涨价，提醒大家的是，部分产品的调价幅度将超过4.1%，所以涨价之后的采购大家要谨慎，因为你最终的采购价格或许不是我们目前网站公布的价格，也就是说，收到你的定单之后，我们须与国外供货商重新确认价格和货期变动情况，要是这样的出入给你造成不便，我们深表歉意。
