An amount increase ofPAI-3 andK10 was observed after theKCswere cultured for48 h in high calcium medium,butat72 h the exprssion ofPAI-3 decreased. The positive stain ofPAI-3 wasmainly localized in perinuclearmembrane in lowcalcium medium and in cytoplasm in high calcium medium. PAI-3 was incorporated into cornified envelope ofterminally differentiated keratinocytes.

METHODS: The BEC were preincubated with crocetin (1, 0.1 and 0.01 μmol/L) for 12 h, then exposed to AGE (100 mg/L). The RAGE mRNA expression was detected by RT-PCR analysis, the intercellular adhesion molecule-1(ICAM-1) was measured by ELISA. The extracellular superoxide ion and thiobarbituric acid reactive substances were assessed with superoxide ion kit and colorimetric assay, respectively The intracellular I2O2 was also detected using the probe 2,7-dichlorofluorescein. The mitochondrial membrane potential and mitochondrial Succinate dehydrogenase were analyzed by the retention of rhodamine 123 (Rh123) and MTT.

The results show that SO2 gas itself does not influence the growth of ZY-1, however, when the SO2 concentration is higher than 50×10^(-6), ZY-1 growth rate and its CO2 fixation rate are all lowered and the pH of the medium is decreased, so measures must be taken to desulphurize or control pH of medium temporality. The presence of NO with concentrations of lower than 300×10^(-6)did not influence the growth of ZY-1 and its CO2 fixation, NO absorbed in the medium is utilized as a nitrogen source. The influence of dissolved soot dust on ZY-1 growth and its CO2 fixation could be ignored once the soot dust in the stack gases was disposed by the original method.
结果表明,烟气中的SO2是以增加培养液中的SO2^(-2)浓度及降低pH的形式来影响ZY-1的生长及其对CO2的固定的,当其浓度大于50×10^(-6)时,需要进行烟气脱硫或控制培养液pH变化来消除其影响;烟气中NO浓度不高于300×10^(-6)时,不影响ZY-1的生长及其对CO2的固定,反而可作为氮源供ZY-1生长用;对经过一般除尘处理的烟气来说,在利用小球藻ZY-1固定CO2时可不考虑溶解性烟尘的影响。
