Using four different Na_2CO_3 concentration as simulating alkaline stress,the relative alkali damage rate of rice germinative energy and germination rate at germination period,RADR of rice root length,seedling height and root number at early seedling stage were looked as evaluation indexes,so the alkaline stress concentration for evaluation of alkaline tolerance at germination period and early seedling stage in rice was studied.

通过采用4种不同浓度的Na2CO3模拟碱胁迫，以水稻发芽期发芽势和发芽率的相对碱害率以及幼苗前期的根数、根长和苗高的相对碱害率为鉴定评价指标，研究水稻发芽期和幼苗前期耐碱性鉴定的碱胁迫条件。

建立了一种非水毛细管电泳同时测定黄连饮片生品与炮制品中小檗碱、巴马汀、药根碱、木兰碱和黄连碱含量的方法。

Under the same concentration, tadalafil induce higher ratio of relation responses in the smooth muscles of CRF rabbit cavernosal strips, compared with papaverine and sodium nitroprussiate, with most significant difference occurring under the concentration indicators of 10-5 mol/L and 10-4 mol/L (P.01). Conclusions The effects of tadalafil on relaxation responses in CRF rabbit cavernosal strips highly depend on its concentration. The effect of tadalafil on relaxation responses in CRF rabbit cavernosal strips is better than that of papaverine and sodium nitroprussiate. Tadalafil may be an effective drug for treating CRF reduced erection dysfunction.

同一浓度下，他达拉非对慢性肾功能衰竭兔阴茎海绵体平滑肌舒张百分比与罂粟碱、硝普钠相比较，舒张百分比均大于罂粟碱和硝普钠，且在10~(-5)mol/L、10~(-4)mol/L浓度，他达拉非对慢性肾功能衰竭兔阴茎海绵体平滑肌舒张百分比，与罂粟碱、硝普钠相比较有显著性差异(P＜0.01)结论他达拉非对慢性肾功能衰竭兔阴茎海绵体平滑肌舒张反应的影响具有浓度依赖性，他达拉非对慢性肾功能衰竭兔阴茎海绵体平滑肌舒张反应的影响优于罂粟碱及硝普钠，他达拉非可能是治疗慢性肾功能衰竭性阴茎勃起功能障碍的理想药物。
