Clonidine (20ug/bilateral), an alpha agonist, produced similar effect as NA; while phentolamine (10ug/unilateral), an alpha antagonist, brought about an enhancement of AA, This phenomenon was observed in the acupuncture effective group, but not in the acupuncture uneffective one. However, propranolol (10ug/unilateral), a beta antagonist, had no effect on AA in these two groups.

RESULTS:(1) ET-1 could increase total protein production, surface area, ERKs activity and ［Ca2+］i in cultured cardiomyocyte in dose-dependent manner at concentrations ranging from 10-9 to 10-7 mol/L. And this effect could be abolished by BQ123, an antagonist of ETA receptor, partly inhibited by PTX, but not by BQ788, an antagonist of ETB receptor.（2）The activation of ERKs and the increase of ［Ca2+］i induced by ET-1 were obviously inhibited by PD98059, a selective ERKs kinase inhibitor, and nifedipine, a calcium channel blocker, respectively. Both antagonists partially inhibited ET-1-stimulated cardiomyocyte hypertrophic response.(3) Staurosporine, a selective PKC inhibitor, could inhibit ET-1-stimulated cardiomyocyte hypertrophic response and increase of ［Ca2+］i, but not affect the activation of ERKs.

结果： ①ET-1浓度依赖性增加新生大鼠心肌细胞蛋白质含量和心肌细胞表面积、ERKs活性及［Ca2+］i浓度，以上作用可被ETA受体拮抗剂BQ123所完全抑制，被百日咳毒素部分抑制，而ETB受体拮抗剂BQ788则无效；②ERKs激酶特异性抑制剂PD98059可完全抑制ET-1激活ERKs的作用，钙通道拮抗剂硝苯地平可明显抑制ET-1介导的［Ca2+］i浓度增加，但二者皆仅部分抑制ET-1介导的心肌细胞肥大反应；③蛋白激酶C选择性抑制剂staurosporine并不能明显抑制ET-1介导的ERKs激活，但可抑制ET-1介导的的［Ca2+］i浓度增加及心肌细胞肥大反应。

Results The pD2 value (the affinity to M-receptors of agonist) of Erycibele alkaloid's miosis is 3.60±0.15 and its IOP lowering action is 3.49±0.07. In the isolated iris contracting experiment, its pD2 value is 6.38±0.12. M3 receptor antagonist is the strongest antagonist in inhibiting the miosis, IOP lowering action and isolated iris pupillary contracting action of Erycibele alkaloid. 0.01% Erycibele alkaloid can cause the decrease of cAMP and the increase of cGMP in the aqueous humor.

The fermentation filtrate of Gvirens , under the concentration of 70%, had not distinct inhibitory activity to B.firmus, the biomass of B.firmus would decrease with above the 70% filtrate of Gvirens, but the fermentation filtrate of B.firmus had not inhibitive role to Gvirens. 7, The cooperation control of both Gvirens and B.firm to the pine needle blight was explored:(1) Pathogen inoculation happened prior to the bio-control treatment for 7 days, however, the disease index and control effect had not distinct differences in any treatments even if combination of the two antagonists, but the susceptibility for different kind of pine were different.(2)when antagonist and pathogen were inoculated at the same time, some control effect to the pine needle blight, including certain extent cooperation control of both Gvirens and B.firm were proved, but it wasn't distinct when two antagonists used separately, and the change of the antagonist concentration had little effect to the control effect.
