Induction of Aryl Hydrocarbon Hydroxylase in Ambystoma tigrinum

Colvin, David P. 12 1900 (has links)
Aryl hydrocarbon hydroxylase (AHH) was induced 15-fold in Ambystoma tigrinum by intraperitoneal injection of 3-methylcholanthrene in corn oil, or 10-fold by addition of aromatic polycyclic hydrocarbons to the aqueous environment of the neotene animal. The cytochrome P-450-associated microsomal enzyme is similar to the inducible, one-gene, autosomal-dominant system typical in the laboratory mouse and man. Differences in optimal temperature for enzyme induction and activity were noted in organ culture of human and Ambystoma tissues, and ratios of benzpyrene metabolites differed between Ambystoma and Mus. The half life of enzyme activity induced in vivo was related to the excretion of hydrocarbon metabolites.

Vertebral development and its development in modern salamanders / Vertebral development and its evolution in modern salamanders

Boisvert, Catherine Anne January 2003 (has links)
Vertebral development patterns have been well characterised in the Paleozoic "lepospondyls" and "labyrinthodonts", as well as in modern amniotes, frogs and caecilians. Each of those groups consistently develop either the neural arches before the centra or the centra before neural arches. Preliminary studies confirmed that members of the Urodela exhibit both developmental patterns. To understand if there is any consistency in patterns of vertebral development within and between families, as well as to investigate the distribution of patterns within the order, 120 salamander larvae from the ten living salamander families were cleared, stained and examined for osteological development. In order to provide a basis of comparison between different developmental stages observed in different families, a staging table was constructed. The complete osteological development of every cleared and stained specimen used in this study was then described. Finally, the general pattern of vertebral development was examined and characteristic patterns for each family were mapped on an accepted phylogeny of salamander relationships.
