Liver and kidney tissue of dab Limanda limanda were analyzed during the Bremerhaven Workshop by irnrnunochemical and catalytic assays for cytochrome P450 1Al induction. Antibodies to cod P450 1Al cross-reacted with a protein of M, = 58 000 daltons in the dab liver samples, suggested to be the dab P450 1Al protein. By employing a recently developed indirect ELISA wlth these antibodies, we observed elevated levels of P450 1Al protein in the innermost stations of the German Bight transect in both liver and kidney (head and trunk kidney) samples. Ethoxyresorufin 0-deethylase (EROD) activities in trunk kidney were also elevated in the innermost stations. Along the drilling station gradient no induction could be detected. Immuno-detection of the cytochrome P450 1Al induction response should provide a convenient indicator for biological effects of several classes of organic contaminants.

Tiede ja magia asetetaan usein vastakkain ja samoin niitä kannattavat ja harjoittavat ihmiset. Isabelle Stengersin mukaan maailma jossa elämme on kyllästetty magialla. Se ilmenee yhteyksinä, joita on muodostettu paikkoihin, joista niitä ei oleteta löytyvän ja joiden voima on suurempi kuin kuvittelemme. Silti arkiajattelussa redusoimme ajatuksen magiasta vain metaforaksi, symboliseksi eleeksi. Se ettemme tunnista magiaa ja sen vaikutusta meihin ja tiedollisiin jäsennyksiimme, voi olla meille haitaksi. Jopa kapitalismin perustana on omanlaisensa magia.
