Methods After injecting different doses of cephalosporins(100, 200, 300, 400μg) into vitreous body of rabbits, we studied the active change of retinal enzymes at different time and observed the histological and ultrastuctural changes of retinae.

方法以不同浓度的先锋霉素Ⅵ(100,200,250,300,400μg)行兔眼玻璃体腔内注射,用酶组织化学染色法测定注射后不同时间(1,3,7d)视网膜琥珀酸脱酶和乳酸脱酶活性的变化,并观察对视网膜组织结构及超微结构的影响。

The finding of the blue-shifted F-He-H... Y (Y=N〓, CO and He) systems, where the proton-donor was incapable of rehybridization, indicated that rehybridization is not a generally application driving force for the blue shift. There were other two novel blue-shifted systems discovered in this study. They were lithium bonding systems and dihydrogen bonding systems. On the basis of state-of-art NBO analyses and potential energy surface analysis, it was demonstrated that Pauli/nuclei repulsions cause the blue shift.
