objective to study the changes of t-pa and t-pa inhibitorduring the acute stage of cor pulmonale.methods to measure the plasmatic activity of t-pa and pai by chrom-substrate in60cases of cor pulmonale,compared with the corresponding index of55cases in the control group.results pai was significantly higher in acute stage than in remission stage of corpulmonale,and t-pa was lower in remission stage than in acute stage.the difference was significant（p.01）.conclusion the unbalance between t-pa and pai can promote the formation of micro-thrombus and further exacerbate high pulmonary pressure.

目的 探讨血浆组织型纤溶酶原激活物及t-pa抑制物在肺心病急性加重期的变化。方法用发色底物法测定60例肺心病急性加重期的血浆t-pa及pai的活性，并与对照组55例肺心病缓解期的相应指标作比较。结果肺心病急性加重期患者pai显著高于肺心病缓解期，而t-pa低于肺心病缓解期，其差异具有非常显著性（p.01）。结论 t-pa及pai关系失衡，有助于动脉内微血栓形成，促进或加重肺动脉高压的形成。

Finally, we established rat model of PF induced by bleomycetin, and observed the interventional action of phenol total base to model. The analysis of experimental result including pathematologic and tissue biochemical indicator showed phenol total base of plumula nelumbinis have some therapeutic action to rat model of PF induced by BLM.

The reseach on activity changes of SOD, POD and CAT during the somatic embryogenesis of Y35 showed:(1) The activty of SOD was from 52.98 to 133.20 U·g-1·h-1, and remained a rising trend after early single embryo forming, this revealed that SOD might be positively correlated to the differentiation of embryogenic cell and the development of somatic embryo.(2) The activty of POD was from 0.05 to 0.50 U·mg-1·min-1, ascended firstly and desceded later, and was highest in embryogenic callus and lowest in late single embryo , this revealed that POD might be positively correlated to the division and differentiation of proembryo mass, while negatively correlated to the development of PEMⅢto late single embryo.(3) The activty of CAT was from 0.86 to 2.81 U·mg-1·min-1, showed an up-down-up trend, reaching to the highest peak at the time of early embryo formating and decreasing to the lowest at the time of early cotyledonary embryo formating, this revealed that CAT might be positively correlated to the development of early single embryo, while negatively correlated to the formation of middle single embryo and early cotyledonary embryo.The changes in activty of SOD, POD and CAT indicated these three antioxidant enzymes coregulated the differentiation and development of embryogenic cells during Larix somatic embryogenesis.4. Differentially expressed cDNA libraries of the stages of proembryo mass and somatic embryo maturation were successfully constructed by suppression subtractive hybridization.

对Y35体细胞胚胎发生过程中抗氧化酶活性变化的研究显示：(1)SOD活性在52.98~133.20 U·g-1·h-1之间，并在早期单胚形成后一直保持上升的趋势，表明其与胚性细胞的分化及体细胞胚的发育均具呈正相关；(2)POD活性在0.05~0.50 U·mg-1·min-1之间，呈现出先下降后升高的趋势，在胚性愈伤组织中最高，而在后期单胚形成时降至最低，表明其与原胚团的分裂和分化呈正相关，但与PEMⅢ向后期单胚的发育呈负相关；(3)CAT活性在0.86~2.81 U·mg-1·min-1之间，表现出升-降-升的变化趋势，在早期单胚形成时升至最高，在早期子叶胚形成时降至最低，表明其与早期单胚的发育呈正相关，而与中期单胚和早期子叶胚的发育呈负相关。

Thrombolytics (eg, tissue-type plasminogen activator ) cannot be used prophylactically in this high-risk setting because of their short duration of action and risk of causing hemorrhage and central nervous system damage.

溶栓剂（如组织型纤溶酶原激活物）因为其作用时间短、可引起出血、中枢神经损害等是在这种高危情况下被禁止预防性应用。
