Antimutagenic effect of broccoli flower head by the ames salmonella reverse mutation assay.

A study was performed to investigate the antimutagenic effect of broccoli flower head by the Ames Salmonella reverse mutation assay. Broccoli flower head being the most highly edible part in the plant was analysed for its antimutagenic effect. Without isolating the phytomolecules, the crude ethanol extract of broccoli flower head was tested for suppressing the mutagenic effect induced by certain chemical mutagens.

Accumulation of 8-hydroxydeoxyguanosine and its relationship with antioxidant parameters in patients with Eales' disease: implications for antioxidant therapy.

Purpose: Eales' disease (ED) is an idiopathic retinal inflammatory disease, which affects the retina of young adult males. Oxidative stress has been associated with the development of various inflammatory diseases. Accumulation of DNA oxidation products has been considered as an early biomarker for assessing oxidative tissue damage.

Elucidation of tumor-promoting potential of a combination pesticide by short-term, in vivo bioassay.

The use of combination pesticide (profenofos 40% + cypermethrin 4% EC) is on the rise in India and elsewhere. Cypermethrin is reported to be a tumor promoter, but its tumor-promoting potential along with profenofos is yet to be studied. A short-term, in vivo test for detection of a tumor promoter is cost-effective, saves time, and requires fewer animals than conventional methods.
