负氧离子水对亚急性湿疹的临床疗效观察

目的：观察负氧离子水对亚急性湿疹的疗效和安全性。方法：收集符合标准的10例亚急性湿疹患者,以负氧离子水洗浴1h,隔日1次,共治疗10次。结果：10例患者全部完成治疗,症状均有不同程度改善,其中,2例（20%）患者疗效指数为100%,达到临床痊愈;4例（40%）疗效指数波动在61%～90%,为显效;4例（40%）疗效指数在20%～60%,为好转。10例患者治疗后血红细胞较治疗前显著升高（P〈0.05）;血白细胞较治疗前显著降低（P〈0.05）;皮肤弹性值较治疗前显著增加（P〈0.01）;血小板、尿常规、过敏原总Ig E测定、心电图等指标较治疗前差异无统计学意义。结论：负氧离子水可一定程度降低患者的湿疹面积及严重度指数（EASI）,改善患者贫血、感染等症状,增加皮肤弹性,且无不良事件发生。

Enzyme-like Activities of Algal Polysaccharide-Cerium Complexes

Water-soluble algal polysaccharides (APS) (alginic acid, fucoidan and laminaran) possess many pharmacological activities. The results of this study showed that the APS- Ce4+ complexes have some enzyme-like activities. Fucoidan and its complex with Ce4+ have activities similar to those of SOD. The activities of laminaran, alginic acid and their complexes are not measurable. The APS do not show measurable activities in the digestion of plasmid DNA. In contrast, the APS- Ce4+ complexes show these measurable activities under the comparable condition when APS bind Ce4+ and form homogenous solu-tions. The laminaran- Ce4+ complex shows the most obvious activity in the digestion of plasmid DNA, pNPP and chloropy-rifos under neutral conditions.
