尿激酶用于治疗玻璃体出血有的获得了令人鼓舞的效果(Forrester et al 1974),有的则结果令人失望(Cleary er al 1974)。病例的选择差不多是相同的,如铅尿病者为最多,其他有高血压、血管意外及过量用抗凝剂引起的玻璃体出血。是什么因素致使有的治疗成功有的则无效? 玻璃体出血的结局,特别是在病理学方面,很少了解。常见到的白内障摘除术中发生的位于玻璃体表面的出血,呈亮红色的血凝块,于几周内即可消失。玻璃体下或视网膜前的出血则仍保

A 3-D chemical transport model (OsLO CTM2) is used to investigate the influences of the increasing anthropogenic emission in India. The model is capable of reproducing the observational results of the INDOEX experiment and the measurements in summer over India well. The model results show that when NOx and CO emissions in India are doubled, ozone concentration increases, and global average OH decreases a little. Under the effects of the Indian summer monsoon, NOx and CO in India are efficiently transported into the middle and upper troposphere by the upward current and the convective activities so that the NOX, CO, and ozone in the middle and upper troposphere significantly increase with the increasing NOx and CO emissions. These increases extensively influence a part of Asia, Africa, and Europe, and persist from june to september.
