BACKGROUND:The resin infiltration technique for masking white spot lesions has obtained a result superior to the conventional remineralization. Up to now, few studies have evaluated the color of carious incipient lesions treated with the resin infiltration.
OBJECTIVE:To assess the color change of caries incipient lesions in the enamel treated with resin infiltration.
METHODS: Forty-eight extracted teeth were exposed to demineralizing solution for 4 weeks to establish artificial caries models. Then artificial caries models were treated with resin infiltration and randomized into four groups: these specimens were immersed in red wine, coffee, tea and artificial saliva for 2 and 4 weeks, respectively. The base line color was evaluated by spectrophotometer. The variation in color (ΔE) was analyzed by one-way analysis of variance and Tukey’s tests.
RESULTS AND CONCLUSION:Al specimens underwent color and lightness changes, irrespective of immersion media. After 2 weeks of immersion, ΔE values were ranked as folows: red wine > coffee > tea > artificial saliva, and there were significant differences between four groups (P < 0.05). After 4 weeks of immersion,ΔE values were ranked as folows: red wine≈ coffee > tea > artificial saliva, and there were significant differences between four groups (P < 0.05) but not between the red wine and coffee groups (P > 0.05). Significant changes in the color were found in the red wine and coffee groups at different time after immersion (P < 0.05). Immersed in red wine, coffee and tea, the?E value was > 3.7, which is not acceptable in clinic. These findings indicate that the color stability of carious incipient lesions located in the enamel treated with resin infiltration is associated with the soak solution and soak time. In addition, immersion in red wine and coffee results in significantly increased color alteration (ΔE) compared with the artificial saliva.

AIM\ To observe the effect of methionine enkephalin(Met Enk) on proliferation and mechanism involved by opiate receptor of peripheral blood lymphocyte(PBL) from patients with systemic lupus erythematosus(SLE). METHODS\ Lymphocyte proliferation assay. RESULTS\ Naloxone (Nal,1?10 -6 mol?L -1 )could block the increasing effect of Met Enk(1?10 -8 ～1?10 -6 mol?L -1 )on the PBL proliferation of normal humans,but there was no direct effect on that. However,Nal could not only block the promotive action of Met Enk on PBL proliferation of SLE patients,but there was a direct decreasing effect on it. CONCLUSION\ Endogenous Met Enk may participate in the abnormal regulation with SLE PBL via opiate receptor.

BACKGROUND:Sodium alginate and chitosan are the polycation and polyanion natural polymer materials respectively, and they can be crosslinking agents complementing each other to form composite gel and avoid the cytotoxicity resulting from some common crosslinking agents .
OBJECTIVE:To prepare the chitosan-sodium alginate composite gel and evaluate its cytotoxicity in vitro. METHODS:Chitosan was dissolved in 0.25 mol/L acetic acid to make a 30 g/L mass concentration solution, and 0.1 mol/L NaOH solution was added to neutralize its acidity. Neutralization of the chitosan solutions leads to the formation of a precipitate in ultrasmal particles. Then the chitosan and 3%sodium alginate solution in deionized water were mixed in 1:1 volume ratio by high frequency oscil ating to produce composite gel. The composite gel were detected by scanning electron microscopy and Fourier transform infrared spectrometry after freeze-drying. The 24-hour and 72-hour leaching solutions of composite gel, 24-hour and 72-hour leaching solutions of polyethylene and phenol solution were added to the L-929 cells’ culture medium respectively in order to evaluate the cytotoxicity of composite gel in vitro.
RESULTS AND CONCLUSION:The results of Fourier transform infrared spectrometry showed the variation of characteristic peak values of composite gel which were different from sodium alginate and chitosan;and under scanning electron microscope, a spatial network structure formed with abundant intervals. Result of the cytotoxicity valuation was qualified for the chitosan-sodium alginate composite gel. These findings indicate that the chitosan-sodium alginate composite gel can be used as tissue engineering scaffold materials.
