Body Burden of Dichlorodiphenyl Dichloroethene (DDE) and Childhood Pulmonary Function

Longitudinal studies have shown that early life exposure to dichlorodiphenyl dichloroethene (DDE) can lead to growth reduction during childhood and adolescence. In addition, DDE exposure has been linked to respiratory tract infections and an increased risk of asthma in children. Our aim was to understand the relationships between DDE exposure and pulmonary function in children, and, particularl...

Promotion of aflatoxin B1-induced hepatocarcinogenesis by dichlorodiphenyl trichloroethane (DDT).

A study of the effect in rats of dichlorodiphenyl trichloroethane (DDT) on hepatocarcinogenesis that is initated by aflatoxin B1 (AFB1). In the first experiment, Buffalo rats were given a single oral dose of AFB1 (5 mg/kg) followed by dietary DDT (100 ppm) for 20 weeks. Neoplastic nodules were observed in 1 of the 14 AFB1-exposed rats, compared with 3 of the 19 rats in the AFB1/DDT group. In th...

Pubertal growth and development and prenatal and lactational exposure to polychlorinated biphenyls and dichlorodiphenyl dichloroethene.

OBJECTIVES Polychlorinated biphenyls (PCBs) and dichlorodiphenyl dichloroethene (DDE) are ubiquitous toxic environmental contaminants. Prenatal and early life exposures affect pubertal events in experimental animals. We studied whether prenatal or lactational exposures to background levels of PCBs or DDE were associated with altered pubertal growth and development in humans. STUDY DESIGN Foll...

IL 22 ( interleukin 22 )

A22 22..22

Four randomised controlled trials (RCTs) and one RCT metaanalysis are featured in the Journal this month. The latter is a review of trials of newer-generation antidepressants and cognitive–behavioural therapy (CBT) for adolescent depression (Dubicka et al, pp. 433–440). In an area of clinical practice plagued by controversy, the authors of this review were able to contribute the finding that ad...
