Objective:To observe the relationship between newborn mice interstitial pneumonia and Ureaplasma urealyticum(UU)infection during the period of pregnancy of a vertical transmission animal model by genital infection with UU during the course of cyesis.

Dynamics of eco-epidemiological model with the vertical infection

Absorbent properties of synthesized carboxylmethylcellulose grafting polyacrylamide with quaternary ammonium group to direct dyes;

Jet printing for textiles with direct dye jet inks;

In this research,fourteen typical direct dyestuffs in 6 types were selected to study their biodegradability and color reductions under facultative condition.

Influence of polyvinylpyrrolidone on dyeing process of direct dyes;

Adsorption of direct dyes with multi-sulfonic groups on chitosan fibers;

Fixation of direct dyes with silica gel;
