In 39 workers, aged 24--56, occupationally exposed to organic solvents of paints and varnishes containing benzene, toluene and xylene, for 55--122 months, activity of peroxydase (Pox) and acid phosphatases (AcP) was determined. In addition, NBT test was carried out in peripheral blood neutrophils. Both AcP activity and spontaneous and stimulated NBT reduction were found to be increased. The authors believe that in people an insignificant exposure to organic solvents of paints and varnishes stimulates neutrophils metabolism.

A one-pot, size-controlled preparation of amine-functionalized silver nanoparticles is possible using poly(ethylenimine) (PEI) as a reducing and a stabilizing agent simultaneously. The PEI-stabilized Ag nanoparticles thus prepared in aqueous phase can further be assembled into 2-dimensional (2-D) arrays at the water-toluene interface by heating. By the addition of benzenethiol (BT) into the toluene, a more robust 2-D film is formed, not only at the interface but also on the inner surface of the sampling bottle. The latter Ag film can also be formed, through brief contact with the mixture, on glass slides and even on dielectric beads and cotton fabrics. These Ag-coated films are highly surface-enhanced Raman scattering (SERS) active and also exhibit a very intense SERS spectrum of 4-aminobenzenethiol (4-ABT) or 4-nitrobenzenethiol (4-NBT) via a place-exchange reaction that takes place between BT and 4-ABT or 4-NBT. In addition, the Ag-coated fabrics would be used as antibacterial gauzes for the treatment of burned skin and also as antistatic mats for the ready dissipation of electrical energy buildup. The present electroless deposition method of Ag is thus expected to serve as a technique in high demand in various fields.

Seed extracts of Nymphia alba Linn. and Lupinus polyphyllus Lindl. were analyzed for fatty acid composition, functional group analysis and antioxidant activity. The petroleum ether extract of seeds were found dominant in unsaturated fatty acids with oleic acid (39.9%) and linoleic acid (29.6%) in L. polyphyllus and linoleic (37.5%) and oleic acid (10.9%) in N. alba. All the defatted seed extracts of N. alba and L. polyphyllus found to have powerful DPPH, ABTS, H2O2 and NBT antioxidant radical scavenging activity with reference to butylated hydroxy toluene (BHT). The defatted seed extracts were further analyzed with functional group analysis through FTIR found to contain numerous functional groups which may be responsible for their antioxidant activity.
