Toxic effects of ozone on murine L929 fibroblasts. Damage to DNA.
Damage to DNA caused by exposure of L929 fibroblasts to ozone was reflected by the generation of strand breaks, DNA inter-strand cross-links and DNA-protein cross-links. Addition of propan-2-ol, a hydroxyl radical scavenger, did not affect the formation of strand breaks. In model experiments it appeared that both purines and pyrimidines were involved in DNA inter-strand and DNA-protein cross-li...
متن کاملToxic effects of ozone on murine L929 fibroblasts. Damaging action on transmembrane transport systems.
Exposure of murine L929 fibroblasts to ozone caused inactivation of the energy-coupled transport systems for 2-aminoisobutyric acid and Rb+. Ozone induced an increase of the apparent Km for 2-aminoisobutyric acid transport, with a constant Vmax, indicating impairment of the carrier function, rather than a decrease in the number of transport sites. The uptake rate of 2-deoxy-D-glucose, on the ot...
متن کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
Effects of Berberine on Cell Cycle, DNA, Reactive Oxygen Species, and Apoptosis in L929 Murine Fibroblast Cells
Berberine, an isoquinoline alkaloid isolated from several traditional Chinese herbal medicines (TCM), exhibits a strong antimicrobial activity in the treatment of diarrhea. However, it causes human as well as animal toxicity from heavy dosage. The present study was conducted to investigate the cytotoxicity of berberine and its possible trigger mechanisms resulting in cell cycle arrest, DNA dama...
