GA had no effect on SMA constriction induced by NE. The reactivity of SMA rings to myricetin was increased at 0, 0.5, 1 hour and 2 hours after shock, and it reached the peak at 2 hours, then it significantly decreased at 3 hours and 4 hours after shock.

结果 SMA血管环对NE的反应性表现为：休克0 h和0.5 h组明显高于正常对照组和其他休克时间点组，休克1 h和2 h组明显低于正常对照组和休克0 h和0.5 h组；18α-GA对NE诱导的SMA血管环收缩反应性无明显影响。

GA antagonized SMA constriction induced by myricetin. The antagonizing effect on myricetin in shock 1, 2 and 3 hours groups was more obvious than that in the other groups. CONCLUSION :At the early stage after hemorrhagic shock, the endothelium-dependent and independent vascular contractile response show a compensatory increase.

SMA血管环对杨梅黄酮的反应主要表现为：休克0、0.5、1和2 h组明显高于正常对照组，于休克2 h达最高点；休克3 h和4 h组明显低于正常对照组，运用18α-GA阻断MEGJ后，各组血管环的收缩反应性较18α-GA作用前明显下降，其中以休克1、2和3 h组下降幅度明显大于其他组。

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。
