Abstract
An in vivo micronucleus assay using albino mice was used to examine the anticlastogenic effects of a crude aqueous extract of Hibiscus sabdariffa fruits in bone marrow cells of mice. Various doses of freshly prepared crude extract of Hibiscus sabdariffa (50, 100 and 150 mg/kg b.w.) were given by gavaging to male laboratory bred Swiss albino mice for 7 days as a dietary supplement followed by a single dose of sodium arsenite (2.5 mg/kg b.w.) After 24 h, the animals were killed and bone marrow smears were prepared and stained in Giemsa. The results show that sodium arsenite effectively induced micronuclei in polychromatic erythrocytes (PCEs). Administration of a crude extract of Hibiscus sabdariffa led to a significant reduction of micronuclei in PCEs. The results also show that a combination of Hibiscus sabdariffa and sodium arsenite reduced significantly the frequencies of micronucleated PCEs induced by sodium arsenite.
