prevented
chemicalinduced skin, liver, oral,
and lung cancers by
increasing the antioxidant activity, altering
the gene expressions,
inducing
apoptosis,
and inhibiting angiogenesis and metastasis. Eugenol, rosmarinic acid, apigenin, and carnosic
acid are also
shown to prevent radiationinduced DNA
damage [2].
Another study confirms
the possible radio-protective effect of tulasi
against high-dose (131)
Iodine exposure [3].
In a study by Monga J
et al, the 50% alcoholic
aqueous extract of
different species of tulasi,
was admini s t e r e d
orally
in
mice and
resulted
32
in significant reduction in
tumor volume, increase
in average body weight,
and the survival rate
of mice. The various
extracts showed modulatory influence against
lethal irradiation doses
of gamma radiation
in terms of radiationinduced chromosomal
damage, while at the
same time induced an
increase in reduced glutathione level (an antioxidant) and GST activi t y
[4].
