Toxic Effects of 8-Methoxypsoralen on Lymphocyte Devision

Summary Cultured human leucocytes have been used to examine the toxicity and phototoxicity of 8-methoxy psoralen (8-MOP). It has been shown that 8-MOP depresses cell turnover at concentrations of 10^–10 M or above. In black light (UVA), 8-MOP inhibition begins at concentrations of 10^–14 M. Patients treated for psoriasis with 8-MOP show concentrations of 10^–6-10^–7 M. The inhibition of cell turnover observed with the present technique is at this concentration 40% for 8-MOP alone and 70% for 8-MOP and black light. These results can be related to the micronuclei and chromosome abnormalities seen in dividing cells.

Zusammenfassung Gezüchtete humane Leukocyten sind für die Untersuchung der Toxicität und der Phototoxicität des 8-Methoxy-Psoralen (8-MOP) verwendet worden. Man hat festgestellt, daß 8-MOP in einer Konzentration von mehr als 10^–10 M die Zellteilung hemmt. Bei 8-MOP und black light (UVA) fängt die Hemmung bei 10^–14 M an. Bei Patienten, die wegen Psoriasis mit 8-MOP behandelt werden, zeigen sich Konzentrationen von 10^–6-10^–7 M. Die mit der hier angewendeten Technik festgestellten Hemmung der Zellteilung beträgt bei dieser Konzentration für 8-MOP allein 40% und für 8-MOP + UVA 70%. Diese Ergebnisse sind mit dem Befund an Mikronuclei und Chromosomabnormalitäten in sich teilenden Zellen in Zusammenhang zu sehen.

Biotin-psolaren labeled cDNA amplicons for genotyping rotavirus strains by dot hybridization assay

A simple method to produce biotinylated probes by utilizing an amine–psoralen to conjugate an ester–biotin to nucleic acid molecules is described. It is simple, rapid, and well suited to label cDNA probes with any PCR-generated amplicon for hybridization assay. Its application to identify or to confirm the G and P genotypes of rotavirus-derived amplicons is described; however, it may be used to label amplicons of any origin. As an alternative or as a complementary test to either PCR-typing assay and/or sequencing, it should reduce considerably the laboratory costs required to genotype fully virus strains in large epidemiological surveys conducted in developing countries.     

Allelism between pso1-1 and rev3-1 mutants and between pso2-1 and snm1 mutants in Saccharomyces cerevisiaee

Summary In the yeast Saccharomyces cerevisiae, allelism between the psol-1 and the rev3-1 mutants on the one hand and the pso2-1 and snm1 mutants on the other, is demonstrated by the comparison of phenotypes, complementation tests and meiotic segregation analysis.
