摘要:
Characterization is absolutely necessary and is a must in order to understand and estimate different silver nanoparticle (nm) size in specific group wise manner which corresponds to group wise in number & sizes, and their importance and effect on biological tissue and organs with agglomeration for nano toxicological studies in environments, the acute toxicity of colloidal silver nano particles (AgNps) were studied in fresh dissected tissues of Swiss Albino mice and their fetuses. In this manuscript, an attempt is made to demonstrate the synthesis and characterization of silver nano particles with a wide range of sizes (from 2.75 nm up to 1908.2 nm in radius) by reducing silver nitrate powder with polyvinyl pyrollidone in aqueous solutions in the presence of a sodium borohydride stabilizer. The resulting particles were found spherical aggregates with a rough surface and poly dispersity index below 18.26% (>0.783 PDI). The particle optical, cumulative, diluents and electrical conductivity properties were examined by dynamic light scattering and zeta potential but morphology was evaluated after examination by transmission electron microscopy & image-j. Silver nanoparticles were directly coated with polyvinyl pyrollidone with a sodium borohydride stabilizer. Optical properties on a single-particle level were studied by means of auto correlation function measurements. The effective poly dispersity index of the charged silver nanoparticles was low enough to form a colloidal crystal at low ionic strength. Colloidal form is found more toxic than suspended particles in 1.5 molar sodium chloride solution;this shows increase of silver nanoparticles size due to agglomeration, will reduce the toxicity but increase teratogenicity.

摘要:
目的 探讨不同的红细胞(RBC)数量对COULTER MAXM型全自动血细胞分析仪测定血液网织红细胞(RET)的影响,以期准确测定重度贫血患者的RET值.方法 测定不同RBC数的血液标本的RET值,观察标本RBC数对COULTER MAXM型全自动血细胞分析仪测定血液网织红细胞(RET)的影响.结果 标本RBC数在2.00~4.50×1012/L范围内时,标本RBC数量对RET测定基本无影响;当标本RBC数低于2.00×1012/L时,标本RET测定值偏高.50例重度贫血患者的血液标本预处理(将红细胞数调整在3.00~4.00×1012/L之间),用COULTER MAXM型全自动血细胞分析仪法测定网织红细胞结果2.57±1.59(X±S)与显微镜目测法同组测定结果2.45±1.58(X±S)相比,二者间无显著差异(P>0.05).结论 通过调整重度贫血患者血液标本的RBC数量,COULTER MAXM型全自动血细胞分析仪可以准确测定其RET结果.
