2.Effect of protective agents on edge closeness of glass monomer cement
Chinese Journal of Tissue Engineering Research 2009;13(8):1582-1584
BACKGROUND: Glass ionomer cement has been a commonly used filling matedal in the clinic. However, glass ionomer easily absorbs water and dissolves in early concretionary phase, which can reduce the leak tightness of the edge of obturator, resulting in slightly leakage. Therefore, protective agents are necessary following glass monomer filling. OBJECTIVE: To compare the effects of three protective agents (vaseline, cocoa butter, luminous paint) on edge closeness of glass ionomer cements. DESIGN, TIME AND SETTING: The controlled observation study was performed at the Central Laboratory, Hospital Affiliated to Medical College, Qingdao University from July to October 2007. MATERIALS: Forty freshly block teeth were used. After cleaning the facing, a 5 mm×3 mm×2 mm cavity was made at 1/3 part near to buccal surface using a high speed turbine engine under water cooling. Tooth facing was coated twice with colorless nail-polish at1 mm from the cavity. Apical foramen was covered with rod wax sheet. Teeth were equally and randomly assigned into control group, vaseline group, cocoa butter group and luminous paint group. METHODS: Glass ionomer cement was filled into the cavity. The filling surfaces were respectively coated with vaseline, cocoa utter and luminous paint in each group. The control group was left intact. Hot-cold cycle test and microleakage test were performed. MAIN OUTCOME MEASURES: The depth from dye penetration into the cavity wall to filling was recorded. RESULTS: Microleakage to different degrees was observed in each group under the microscope. However, the penetration depth was deeper in the control group than other three groups (P < 0.05). No significant difference in penetration depth was detected among the vaseline, cocoa butter and luminous paint groups (P > 0.05). CONCLUSION: Vaseline, cocoa butter and luminous paint have good effects on wet prevention.

4.Experimental study on cyclosporine A drug delivery system in prevention of posterior capsule opacification after intraocular lens implantation in rabbits
Journal of Pharmaceutical Analysis 2008;20(4):262-266
Objective To study the effect of cyclosporine A drug delivery system (CsA-DDS) on the prevention of posterior capsule opacification (PCO) after experimental intraocular lens implantation in rabbit eyes. Methods Twenty healthy New Zealand white rabbits, whose left eyes and right eyes were used respectively as experiment eyes and controls, were subjected to extracapsular lens extraction and artificial lens implantation. During the operation, CsA-DDS with poly (lactideco-glycolide) as carriers or empty DDS was implanted in the capsular bag for the experimental eyes and controls respectively. After the operation, anterior chamber reaction, intraocular pressure (IOP) and CsA concentration were monitored and twelve weeks after the operation, the eyes were extracted for histopathological and morphological examinations. Results There were no differences between the two groups in conjunctival congestion,IOP change and anterior chamber reaction. PCO was less severe in the experimental eyes than in the controls. Light microscopy revealed that posterior capsular membrane in the experimental eyes was slick, with no obvious proliferation,whereas in the controls, there were lens epithelial cell proliferation and cortex regeneration of different degrees.Morphological examination with electron microscope showed that in the experimental eyes, lens epithelial cells did not function actively and apoptosis occurred, whereas in the controls, epithelial cells presented active function. No marked ultrastructural changes were found in either group. Conclusion Cs-DDS can inhibit PCO after intraocular lens implantation in rabbit eyes and does not have toxic effects on the surrounding ocular tissues. Therefore, it has a good potential for clinical use in prevention of PCO.
