不同方法对手术室空气消毒效果观察 总被引:7,自引:3,他引:7
为了比较紫外线照射法、过氧乙酸气溶胶喷雾法、静电消毒器法对手术室空气消毒效果,采用对手术室消毒前后空气采样检测方法,观察3种方法对空气中自然菌的杀灭效果。结果,3种消毒方法分别单独作用30min,对手术室空气中自然菌消除率均可达到98%以上;3种方法在作用停止后维持消毒水平均不超过60min,只有静电消毒法可以作为人在条件下持续消毒,但60min后亦不能维持原消毒效果水平;采用两两联合使用,以静电消毒法与过氧乙酸气溶胶消毒法联合使用效果最好。因此,可采用过氧乙酸气溶胶喷雾消毒后,再用静电消毒法维持对手术室空气进行人在条件下消毒。 相似文献

After guinea pigs were sensitized with human
liver specific lipoprotein (HLSP) for a prolonged
duration, collagen formation by hepatocytes in situ
was observed. Possibly, the work reported
here provides for the first time direct morpho
logic evidence that hepatocytes participate in colla
gen formation in the liver. Our experiment also
showed that immune reactions induced by HLSP
can stimulate liver cell to produce collagen. These
findings may be of great significance iii the inter
pretation of the pathogenesis of liver fibrosis and
liver cirrhosis. 相似文献

器官纤维化及硬化是许多慢性疾病和老龄化引起的常见病变,其特点是实质细胞的损伤和减少及间质胶原纤维的增生和积累,而实质细胞是否参与间质胶原纤维的增生是个值得深入研究的问题。本实验观察在致病因子作用下,胰腺腺泡细胞及导管上皮细胞的改变。 相似文献
