高脂血症大鼠红细胞扫描电镜观察

目的 :探讨高脂血症红细胞形态变化和临床意义。方法 :Wistar大鼠分为正常对照组 ( NC)和高脂血症组 ( HL,喂饲高脂饲料 ) ,利用扫描电镜观察红细胞形态改变并计数分类。结果 :与 NC组比较 ,HL组的正常红细胞百分比由 76.4 %减少到 4 5.7%、棘型红细胞、球口型红细胞、靶型红细胞分别由4 %、2 .2 %、1.5%增加到 17.3%、10 .4 %、5.8% ,嵴型和其它异型红细胞也略有增加。结论 :高脂血症的异型红细胞明显增加。     

预测加氢裂化过程的产率

以缓和加氢裂化数据为基础,对于两种典型的加氢裂化动力学模型－－Stangeland模型和改进MHC模型,使用Shor最优化法进行了参数的拟合,比较了这两种动力学模型的结果、算法、复杂度以及预测能力。结果表明,改进MHC模型是一种更为合理的动力学模型,该模型也可用于实际加氢过程。

激光焊接对金瓷结合的影响

OBJECTIVE: This study was aimed to investigate the bonding effect of laser welding on ceramic fused to metal. METHODS: Ten laser welded CW-PA ceramo-alloy rods were fused with porcelain at fusion zone. The porcelain-metal bond strength was measured with pull-through test. SEM examination and EDAX analysis were performed. Ten non-welded CW-PA ceramo-alloy pull-rod plates were used as comparison. RESULTS: The results showed that the bond strength of laser welded sample was 41.32 +/- 6.69 MPa, approaching to 45.71 +/- 9.98 MPa of the non-welded sample (P > 0.05). The microscope displayed the interface compacted union of the two phase boundary. There was no change in the elements and their ratio at the fusion zone. CONCLUSION: These results indicate that laser welding does not affect ceramic fused to metal.     

尖锐湿疣Fas、bcl—2、Ki—67的表达与细胞凋亡的关系

OBJECTIVE: This study inquired into the significance and relationship of apoptosis to the regulation and proliferation of condyloma acuminatum(CA). METHODS: Apoptotic cells were detected in situ by terminal deoxynucleotidyl transferase-mediated-dUTP nick end labeling (TUNEL). The detection of Fas, bcl-2 and Ki-67 expression was performed using immunohistochemical staining in 28 specimens of CA. RESULTS: Apoptotic cells were found in 24 cases (85.7%) in keratinocytes. All of the in 28 cases(100%) had Fas and Ki-67 positive expressions, but only 8 cases (28.6%) had bcl-2 mild or moderate expression. The disease severity (serious, moderate and mild) groups did not significantly differ in apoptotic index (AI), Fas, bcl-2 and Ki-67 positive expression (P > 0.05). There was positive correlation between AI and Fas(r = 0.866, P = 0.000). bcl-2 and Ki-67 were negatively correlated with AI (r = -0.416, P = 0.018; r = -0.475, P = 0.006). CONCLUSION: It is suggested that apoptosis in keratinocytes may play an important role in inhibiting the proliferation of virus, that Fas may be an upregulative factor and bcl-2 may be an inhibition factor to apoptosis, and that excessive Ki-67 expression may be associated with the acceleration of cell cycle.
