After 8 or 16 h, DNA was isolated from the livers and purified to constant specific radioactivity. Enzymatic digestion to deoxyribonucleotides and separation by HPLC revealed about 90\% ofthe DNA radioactivity eluting in the form of possible TBOH-nucleotide adducts. The extent of this genotoxicity, expressed in units of the Covalent Binding Index, CBI = (~mol TBOH bound per mol nucleotide)/(mmol TBOH administered per kg body weight) spanned from 8 t~ 17, i. e. was in the range found with weak genotoxic carcmogens. Ames test: low doses of ß-TBOH increased the number of revertants in Salmonella strain TAl 00 reproducibly and m a dose-dependent manner. The mutagenic potency was 0.2 revertants per nmol after preincubation of the bacteria (20 min at 37° C) with doses between 30 and 60 \(\mu\)g per plate (47 and 94 \(\mu\)g/ml preincubation mixture). Above this dose, the number of revertants decreased to control values, accompanied by a reduction in survival. The addition of rat liver S9 inhibited the mutagenicity. DNA binding in vitro: calf thymus DNA was incubated with tritiated ß-TBOH with and without rat liver S9 Highest DNA radioactivities were determined in the absence of the "activation" system. Addition of inactive S9 (without cofactors) reduced the DNA binding by a factor of up to 20. Intermediate results were found with active S9. DNA binding in Salmonella: ß-TBOH was irreversibly bound to DNA isolated from S. typhimurium TA100 after incubation of bacteria with [\(^3\)H]ß-TBOH. Conclusions: Covalent DNA binding appears to be the mechanism of an activation-independent ("direct") mutagenicity of TBOH which is not easily detected because of the bactericidal activity. The genotoxicity risk arising from exposure of humans to trenbolone residues in meat was estimated using the in vivo data and compared to that from the exposure to unavoidable genotoxins aflatoxin B1 and dimethylnitrosamine. It ts concluded that trenbolone residues represent only a low genotoxic risk.}, subject = {Toxikologie}, language = {en} } @article{MollBoesingSchneider1988, author = {Moll, Heidrun and B{\"o}sing-Schneider, Rita}, title = {The transplantation barrier of nude mice}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-46045}, year = {1988}, abstract = {Syngeneic memory cells can be stimulated to yield a secondary immune response after their transfer into irradiated euthymie recipients as well as into young thymusless nude mice. It is shown that nude mice older than twelve weeks of age are not permissive towards memory cell activation as it is found in non-irradiated euthymie animals. This barrier to isogeneie or congeneic cells seems to be caused by a pool of cyclophosphamide-sensitive cells. Since young nude mice could be rendered as unpermissive as older nude mice by pretreatment with either PNA-agglutinable thymus cells or nylon-wool passed spleen cells, it is suggested that an increased number of precursor T cells in older nude mice might induce this effect. Further experiments with monoclonal antibodies against the Lyt-l, Lyt-2, and L3T4 marker on T cells indicate that T -helper/inducer activity might be required to establish the "isogeneie barrief" in nude mice.}, language = {de} } @article{ScheerDabauvalleMerkertetal.1988, author = {Scheer, Ulrich and Dabauvalle, Marie-Christine and Merkert, Hilde and Benavente, Ricardo}, title = {The nuclear envelope and the organization of the pore complexes}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-34275}, year = {1988}, abstract = {No abstract available}, language = {en} } @article{EngelsPeyerimhoffKarnaetal.1988, author = {Engels, Bernd and Peyerimhoff, S.D. and Karna, S.P. and Grein, F.}, title = {The hyperfine coupling constants of the five lowest states of CH : An ab initio MRD-CI study}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-58807}, year = {1988}, abstract = {No abstract available}, subject = {Organische Chemie}, language = {en} } @article{WinotoMorbachLeyhausenMuellerRuchholtzetal.1988, author = {Winoto-Morbach, S. and Leyhausen, G. and M{\"u}ller-Ruchholtz, W. and Ulrichs, Karin}, title = {The Electromagnetic Separation Principle: A Basis for Human Pancreatic Islet Transplantation}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-82520}, year = {1988}, abstract = {No abstract available}, subject = {Allergie}, language = {en} } @article{KurtzSchneider1988, author = {Kurtz, Beth E. and Schneider, Wolfgang}, title = {The effects of age, study time, and importance of text units on strategy use and memory for texts}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-87408}, year = {1988}, abstract = {This study investigated study behavior and recall of a narrative text as a function of the reader's age, study time, and importance level of text units.
