Due to the severe consequences of potential overdoses paracetamol (PCM) on human body, measurement PCM in pharmaceutical and biological samples is essential.

He-Ne laser irradiation (0.01 -6 3/cm3) of the blood and neutrophile suspension in vitrowas shown to modulate reactive oxygen species (RDS ) product ion in healthy donors. Intravascular laser irradiation of the blood ( 5 mW, 30 minutes, daily) of the patients with chronic gastric ulcer during first 5 days resulted in increasing stimul-k-duced ROS production in patients with the low initial chem...

Chemiand bioluminescence measurements have become extremely popular in recent years. They are often used to determine the amount of a specific unknown present in a sample, and in the last decade, have become extremely important in the study of gene expression and gene regulation. Chemiluminescence is the light emitted by a chemical reaction and bioluminescence is a type of chemiluminescence in ...

Participation of singlet molecular oxygen (1O2) in peroxidation of dopa and dopamine was studied by measurements of chemiluminescence spectra, the influence of solvents with various lifetime of O2 (1 delta g) and O2 (1 delta g)-quenchers on quantum yield of chemiluminescence. A decrease of absorption and fluorescence intensities of 1,3-diphenylizobenzofuran (DPBF) was also studied in the presen...

Construction of portable device for fast analysis of energetic materials is described in this paper. The developed analytical system consists of two main parts: a miniaturized microcolumn liquid chromatograph of unique construction and original chemiluminescence detector. This novel portable device is able to determine selectively most of nitramineand nitroester-based explosives as well as inor...

A large number of techniques cxist though some arc more suitable than others for the measurement of a particular compound, considerations being given to its size and its concentration. Howcver, all immunoassays require two components, firstly an antibody capable of specifically binding the compound and, secondly, a tracer which permits this binding reaction to be observed. In classical radioimm...
