Objective: To analyze the effects of high-frequency electromagnetic field (HF-EMF, 30 MHz, 0-1600 V/m) on the apoptosis and ultramicrostructure of the hippocamp and demonstrate the cytotoxicity of hippocamp.

Methods: 120 Wistar female adult rats were randomly divided into ten groups based on body weight with different levels of 30 MHz electromagnetic field (0, 25, 100, 400, 1600 V/m) for eight hours daily. Five group rats were irradiated for three days.

Objective: To study on the effects of sub-chronic exposures to high-frequency electromagnetic field (HF-EMF) on the estrous cycle, ovarian pathological changes and related hormones and preliminarily investigate the female genital toxicities of HF-EMF in rats.

Methods: 60 Wistar female adult rats were randomly divided into five groups based on body weight and radiated with different levels of 30 MHz electromagnetic field (0, 25, 100, 400 and 1600 V/m) for eight hours daily. Weekly the rats were continuously exposed five days.

Objective: To study the epidemiology and etiologic characteristics of a Dengue fever outbreak in Fuzhou from the beginning of September to the end of October in 2004 in order to understand the source of infection.

Methods: Data on descriptive epidemiology was collected to study the characteristics and related factors to the epidemic. Dengue virus was isolated through the use of C6/36 cell line while viral serotypes were identified by indirect immunofluorecent assay with type-specific monoclonal antibody.
