Structure and chromosomal localization of the human 2',3'-cyclic nucleotide 3'-phosphodiesterase gene.

Human brain cDNA clones for the myelin associated enzyme 2',3'-cyclic nucleotide 3'-phosphodiesterase (CNPase) have been isolated and sequenced. The only 5' untranslated region (UTR) sequence found was that of a human CNPII mRNA, with no direct evidence for a CNPI mRNA. Human CNPase cDNAs were used to isolate genomic clones containing the human CNPase gene which is 9 kb long. Four exons were identified, separated by three introns, and the sequence of each exon and intron/exon boundary has been established. The polymerase chain reaction (PCR) was used to detect the presence of the human CNPase gene in DNA from a panel of rodent/human somatic cell hybrids. By this means the human CNPase gene was mapped to chromosome 17. In situ hybridization of a human CNPase genomic clone to metaphase chromosomes further localized this gene to chromosomal band 17q21.

The [14C]-aminopyrine breath test. A comparison of different forms of analysis.

1 Following ingestion of [14C]-aminopyrine, breath 14CO2 data were analysed from normal individuals, patients with hepatic disease, epileptics receiving anticonvulsant therapy and volunteers before and after treatment with glutethimide. 2 The 'standard' 2 h [14C]-aminopyrine breath test discriminated successfully between the main groups but failed to detect the change in microsomal enzyme function produced by glutethimide. 3 A 'modified' form of the 2 h breath test calculated from the area under the breath specific activity curve detected the increase in demethylation following glutethimide. 4 The breath elimination constant (Kb) derived from the breath 14CO2 disappearance curve was as sensitive as the 'modified' 2 h breath test and was simpler to compute. 5 Glutethimide 500 mg/day for 14 days resulted in a 42% increase in the metabolic clearance of antipyrine and a 26% increase in demethylation of [14C]-aminopyrine.
