RESUMEN
ZnO and CdO pellets with and without Mn doping were prepared by using Hydraulic pressure machine at room temperature. The effect of Mn content (1,3,5 wt % ) on the electrical properties have been carried out by Keithley meter. The result shows that the resistivity decreases as increasing Mn content. Impedance analyzer are used for dielectric behavior and results shows that decrement of dielectric constant as well as dielectric loss with the increment of frequency
RESUMEN
An important role of oxidative stress for the development of vascular and neurological complications has encouraged us to undertake a study to assess the oxidative stress induced nerve conduction deficits among cigarette smokers. Eighteen regular male cigarette smokers and twenty nine male non - smokers were diagnosed for clinical neuro-physiological tests viz., motor and sensory nerve conduction velocity (MNCV and SNCV) and redox status. Significant depletion of reduced glutathione (GSH) level (p < 0.05) and significant increase in malondialdehyde (MDA) level (p < 0.01) was found in smokers compared to non - smokers. Motor and sensory nerve conduction velocity showed no significant difference among smokers compared to non - smokers. The present study shows that smoking can induce oxidative stress among smokers but could not exacerbate to nerve conduction deficits.
