The aim of the present work is to investigate the effect of the He-Ne l.ser irradiation on the whol. human bl.od (HB) in order to enhance the conditions of conservation. The HB was irradiated by He-Ne l.ser;(λ = 632 nm, continuous wave, power 30 mW, 2 mm diameter beam spot), el.ctrical.properties and compl.te bl.od count CBC were measured at three doses (0.0287, 0.0563 and 0.198 j.cm3) to the rel.vant best exposure dose during storage periods 9, 24, 30, 35 & 50 days. The irradiation process with the sel.cted dose was performed by the exposure of the l.ser beam on the bl.od sampl. fl.w through narrow tube of cross section area, 0.0831 cm2. Bl.od diel.ctric parameters, (el.ctric conductivity, diel.ctric constant, diel.ctric l.ss and dipol. moment) and CBC, (red bl.od cel., white bl.od cel., hematocrit, hemogl.bin, mean corpuscul.r vol.me, mean corpuscul.r hemogl.bin, and mean cel. or corpuscul.r hemogl.bin in concentration) were measured. The obtained resul.s were compared with that of the control.and showed that the best irradiation exposure dose suitabl. for increasing the time of bl.od storage with minimum changes in properties is 0.198 j.cm3 and storage period of about 50 days. The present study reveal.d that irradiation by He-Ne l.ser coul. be considered a good means to improve the conservation conditions of human bl.od.

文章报道了产自云南寒武系第三阶小石坝生物群的小西德尼虫新种(Sidneyia minor ***.),为西德尼虫属(Sidneyia)目前所发现的最古老物种.该新种具有其他已知小西德尼虫的一些典型特征,如新月形的头甲两侧后部具眼窝(notches),柄眼从眼窝处伸出,此外,最重要而且从未知晓的是显微-CT检测显示的头甲下3对触角后头部附肢.文章基于小西德尼虫新种和模式种的特征以及谱系分析结果,确认西德尼虫类与其他的异尾虫类(vicissicaudatans)构成姊妹群,归属物种显著分异的类肢动物(Artiopoda).
