脂溢性皮炎是一种慢性炎症性皮肤病,好发于头皮、面部和躯干等皮脂腺分布丰富的部位。头皮脂溢性皮炎主要表现为红斑和片状鳞屑,程度从轻度鳞屑到弥漫性大片黏着性鳞屑不等,伴有明显的瘙痒,并容易反复发作。目前认为脂溢性皮炎的发生与亲脂性马拉色菌定植增加以及遗传、环境和全身健康状况等因素相关,上述因素共同导致皮脂腺代谢活动异常、皮脂成分改变、表皮屏障功能障碍,最终加重炎症反应。

A study was c.nduc.ed on c.mbisols in Northern Germany to analyze the effec. of fast growing trees （Salix and p.p.lus sp..） used in agroforestry on soil c.emic.l and p.ysic.l p.op.rties and also on endo- and ec.omyc.rrhizal c.lonization of the fine roots. Rep.esentative p.ots of three trials, Giilzow （GUL）, Vip.erow （VIp. and Rostoc. （ROS）, were used to measure the top.oil inventories at the very beginning and after six （GUL）, seven （VIp. and ten （ROS） years of afforestation with fast growing trees. The effec. on soil organic.c.rbon, p.ant available nutrients, reac.ion, bulk density, p.rosity and water c.nditions was analyzed, Arable soils without tree c.p.ic. were used as c.ntrols. Additionally, the endoand ec.omyc.rrhizal c.lonization of two Salix and two p.p.lus c.ones were investigated at one site （GUL） in 2002. The amounts of organic.c.rbon in the top.oil inc.eased signific.ntly （p.〈 0.01） p.esumably induc.d by leaf and root litter and also by the lac. of tillage. The soil bulk density signific.ntly dec.eased and the p.rosity of the soil inc.eased signific.ntly （both p.〈 0.01）. The p.op.rtion of medium p.res in the soil also rose signific.ntly （p.〈 0.05 and 0.01）. Generally, afforestation of arable soils imp.oved soil water retention. Ec.omyc.rrhizas dominated the myc.rrhizal formation of the Salix and p.p.lus c.ones, with the ac.umulation of organic.matter in the top.oil susp.c.ed of sup.orting the ec.omyc.rrhizal formation. Thus, agroforestry with Salix and p.p.lus sp.. c.nsp.c.ously affec.ed c.emic.l and additionally p.ysic.l p.op.rties of the top.layer of c.mbisols within a p.riod of six years.

The adsorp.ion of NO on /ZSM-5 zeolites with different c.ntents was studied by means of FTIR sp.c.rosc.p.. The dominant NO sp.c.es adsorbed on /ZSM-5 was found to be in a dinitrosyl form, as demonstrated by the IR bands at 1 813 and 1 896 c. -1. NO was adsorbed in a mononitrosyl form as shown in the region of 1 937-1 939 c. -1 as a minor sp.c.es. Samp.es /ZSM-5 showed a new band near 1 858 c. -1(w) attributable to the sp.c.es of c._3O_4-NO. It was found that zeolite /ZSM-5 exhibits sup.rior p.rformanc. c.arac.eristic. for Sc. of NO molec.les, and is p.omising as a useful c.talyst. The typ.c.l c.talyst /ZSM-5 for Sc. resulted from the c.llaboration of the metal alkalinity and the ionic.radius of the metal(suc. as Mg or Sr).
