[Infection status of and its related knowledge and behavior among special population in Changzhou City].

To investigate the prevalence of infection and related knowledge and behavior among special population in Changzhou City, so as to provide the evidence for formulating effective measures of toxoplasmosis prevention. The pregnant women and patients with neoplasia in Changzhou hospitals, and livestock and poultry breeding or processing workers were selected as the subjects of the study. Venous blood samples were collected from each participant for detecting IgG and IgM antibodies against by ELISA.

[Analyais of infection and related factors among special population in Changzhou City, Jiangsu Province].

Objective: To understand the prevalence of infection and related factors among special population in Changzhou City, so as to provide the evidence for formulating toxoplasmosis prevention measures.

Methods: The venous blood was collected from participants in Changzhou City for detecting IgG and IgM antibodies against by ELISA; and an epidemiological questionnaire investigation was also conducted.

Results: Among the total 400 respondents detected, the prevalence of infection was 15.

Direct chiral resolution and its application to the determination of the pesticide tetramethrin in soil by high-performance liquid chromatography using polysaccharide-type chiral stationary phase.

A high-performance liquid chromatography method is presented for the enantioseparation and quantitation of tetramethrin. The separation is achieved on amylose 3,5-dimethylphenyl-carbamate CSP (Chiralpak AD-H column) using a mobile phase consisting of a mixture of n-hexane-ethanol-2-propanol (99:0.9:0.
