AIM:To investigate the effects of propofol on ammonia-induced neocortical astrocyte aquaporin-4 expression in rats and its mechanism. METHODS:Astrocytes were separated from newborn Sprague Dawley rats. Glial fibrillary acidic protein,the specific protein of astrocyte,was labeled by cell immunofluorescence method. The purity of astrocyte achieved to 95% was considered to be used in the study. Grouping:cultured astrocytes were randomly divided into 5 groups (n=3):normal control group (N); ammonia-incubated for 24 h group (NH_4Cl-24 h); p38 antagonist SB203580 (10 μmol/L) pretreated group (SB); propofol (10 μmol/L) pretreated group (P); solvent (DMSO) control group (C). SB203580,propofol and DMSO were pretreated for 30 min before astrocytes were exposed to NH_4Cl. Cell morphology was assessed by light microscopy. The expression of aquaporin-4; p38 and p-p38 were detected by Western blotting. RESULTS:Astrocytes were found significant swelling when exposed to 5 mmol/L NH_4Cl in NH_4Cl-24 h group compared to control group. Pretreatment with propofol and SB203580 decreased astrocyte swelling. No significant change in total p38 in all groups was observed (P>0.05) by Western blotting analysis,while the levels of p-p38 and AQP4 in group SB and group P were significantly decreased compared to group C and group NH_4Cl-24 h (P<0.05).CONCLUSION:The expression of AQP4 is regulated by p38 pathway. Propofol pretreatment down-regulates aquaporin-4 expression through preventing the ammonia-induced p38 phosphorylation.

OBJECTIVETo analyze the changes in CIE L*, a*, and b* at cervical, body, and incisal sites after tooth bleaching by using a spectrophotometer.

METHODSSixty-seven intact and healthy maxillary central incisors were in-vestigated. These incisors were darker than A3 according to the Vita Classical shade guide. The CIE tooth shade parameters L*, a*, and b* were simultaneously recorded at three tooth areas (cervical, body, and incisal) with a spectrophotometer before and after tooth bleaching (35%H2O2 coordinating with Beyond whitening accelerator irradiating). The shade dif-ferential (DeltaE) was calculated. ANOVA, paired t-test, and Pearson correlation analysis were used for data analysis.

RESULTSThe efficacy rates of tooth bleaching were satisfactory, with 86.6%, 86.6%, and 85.1% in the cervical, body, and incisal sites, respectively. The average values of DeltaE were 5.09, 4.44, and 4.40 in the cervical, body, and incisal sites. Tooth bleaching significantly increased L* and significantly decreased a* and b* in all tooth areas (P < 0.01). The decreasing range of Deltab* was more than the increasing range of DeltaL* at the cervical site; opposite results were observed at the incisal site. A positive correlation was detected between baseline b* and DeltaE.

CONCLUSIONThe spectrophotometer could objectively evaluate the whitening effect of tooth bleaching at the different tooth sites. The tooth bleaching system (35%H202 coordinating with Beyond whitening accelerator irradiating) exerts powerful bleaching actions in most of the tooth areas investigated. The order of tooth bleaching effectiveness is cervicalbody>incisal. Yellow coloration is decreased mainly at the cervical site, and brightness was increased mostly at theincisal site. The effectiveness of tooth bleaching increases as the baseline b* value increases.
