We proposed a new method for the study of molecular dynamics and fluidity of the living and model biomembranes and surface systems. The method is based on the measurements of the sensitized photoisomerization kinetics of a photochrome probe. The cascade triplet cis-trans photoisomerization of the ex

Chemico-biological interactions.Chem Biol Interact.1990;76(1):47-62.
Tritium-labeled trans-4-dimethylaminostilbene (DAS) and trans-4-acetylaminostilbene (AAS) were administered orally to female Wistar rats. RNA and DNA were isolated from livers after 24 h and 28 days. Hydrolysates were analyzed by gel filtration and HPLC. Total binding to nucleic acids and elution pr

Tissue specific, acute toxic effects of the carcinogen trans-4-dimethylaminostilbene.

Marquardt P, Romen W, Neumann HG.
Archives of toxicology.Arch Toxicol.1985 Jan;56(3):151-7.
The acute toxicity of the carcinogen trans-4-dimethylaminostilbene was studied in Wistar rats. The animals die after oral administration of 50 mg/kg (LD50) with a latency period of 11 days. Specific lesions of the stomach epithelium together with acute bone marrow incapacity and toxic effects on per
