Attachment process of capsular and intraocular lens and its effect on visual quality after cataract surgery / 国际眼科杂志(Guoji Yanke Zazhi)

@#The adhesion of capsule and intraocular lens(IOL)is a common phenomenon after cataract surgery. At present, there are increasing researches on the adhesion between the capsule and IOL at home and abroad. In this paper, we will review the adhesion process between the capsule and IOL, morphology, related factors that affect the adhesion, and its influence on the visual quality.

Effect of anterior chamber depth on refractive shift after cataract surgery / 国际眼科杂志(Guoji Yanke Zazhi)

@#The fluctuation of anterior chamber depth(ACD)is one of the main causes of refractive shift after cataract surgery. Currently, there are numerous studies on the changes of ACD after cataract surgery worldwide. This article reviews the trend of the change of ACD after cataract surgery, and the influence factors and accompanying refractive shift.

Isolation and Characterization of Collagenolytic Enzyme-Producing Strain from Rotten Hides and Primary Analysis of the Enzyme Property / 微生物学通报

Bacteria isolated from rotten hides,one identified as Pseudomonas aeraginosa later, were shown to decompose fresh hides completely in 48 hours at room temperature. Strongly collagenolytic activity was detected when native collagen from calfskin was used as substrate. The optimal reaction pH value and temperature of the collagenace produced by P.aeraginosa are 7.5 and 32℃ respectively. EDTA and EGTA inhabit the collagenolytic activity severely while PMSF has little effect on it. Not only media components but also fermentation conditions have differents effect on the production of this collagenolyic enzyme.
