The anticlastogenic effect of the herbal preparation Loshtak on rats a
nd mice was tested using the same scheme of treatment and doses of the
preparation as are employed in medical practice. It was shown that in
tragastric administration of Loshtak results in a statistically signif
icant. decrease in the clastogenic effect of cyclophosphamide injected
48 h after the end of treatment with Loshtak. High doses of Loshtak d
id not induce any increase in the number of micronuclei in mouse bone
marrow cells. Possible mechanisms responsible for the anticlastogenic
effect of Loshtak are discussed.
