    Notes: Abstract. Since the early 1970s selective screening for inherited metabolic disorders has been performed in larger childrens hospitals or metabolic centres of the former East-Germany. As a rule the following methods were employed: initially paper chromatography, drop, dip and spot tests, later on thin-layer chromatography and more recently enzyme analysis, gas chromatography, mass spectrometry and HPLC. Normally urine, blood or leucocytes were investigated. The diagnoses were confirmed in metabolic centres in Greifswald, Berlin or Leipzig or in collaboration with specialized laboratories abroad. About 130 000 subjects from former East Germany as well as from different East European countries were investigated, of which 365 patients were diagnosed and classified into roughly 40 various metabolic diseases. The proportion of positive diagnoses was 1 in 400.

    Notes: Summary Cytochrome P-450, detectable in n-hexadecane-grown cells of Acinetobacter calcoaceticus, is not found during growth on complex media, sugars, or various metabolic indermediates, such as mono- or dicarboxylic acids. Cytochrome P-450 formation is observed after shifting cells from a non-hydrocarbon medium to a minimal medium with n-hexadecane as the sole source of carbon, or after addition of n-hexadecane to cultures growing on a non-inducing carbon source. The content increases with time. Induction of cytochrome P-450 is inhibited by streptomycin, chloramphenicol, and rifampicin. Besides n-hexane, other n-alkanes from n-hexane up to n-hexadecane are inducers, whereas cetyl alcohol or palmitic acid are not. The results indicate that the occurrence of cytochrome P-450 in n-alkane-induced cells reflects a de novo protein synthesis. Regulation seems not to be governed by catabolite repression but by the presence of an inducer molecule, which is either an n-alkane or a very similar molecule.
