Lymphoproliferative responses in cord blood and at one year: no evidence for the effect of in utero exposure to dust mite allergens.

Background: Maternal allergen exposure beyond the 22nd week of pregnancy may be important in foetal T cell priming. Allergen-specific cord blood mononuclear cell (CBMC) immunoproliferative responses without corresponding bacterial antigen responses (tetanus toxoid), have been suggested as evidence of in utero sensitization.

Objectives: To investigate the relationship between lymphoproliferative responses at birth and at 1 year with maternal and 1-year infants house dust mite allergen exposure.

The effect of dry heat on mite, cat, and dog allergens.

Background: Various techniques have been tried in an attempt to reduce allergen levels in homes. This study investigated the effect of dry heat on mite, cat, and dog allergens.

Methods: Samples (50 mg) of Dermatophagoides pteronyssinus and D.

Relationship between serum tryptophan and tryptophan metabolite levels after tryptophan ingestion in normal subjects and age-related cataract patients.

1. Cataract is the single major cause of blindness worldwide; however, the reasons for the development of this condition remain unknown. It has been suggested that the essential amino acid tryptophan may be implicated in the aetiology but definitive evidence has been lacking.
