title: The in vivo rodent micronucleus assay of Kacip Fatimah (Labisia pumila) extract.
abstract: Kacip Fatimah also known as Labisia pumila (Myrsinaceae), is a traditional herbal medicine with a long history in the Malay community. It has been used by many generations of Malay women to induce and facilitate childbirth as well as a post-partum medicine. We tested the genotoxic potential of Kacip Fatimah in bone marrow cells obtained from Sprague-Dawley rats using micronuclei formation as the toxicological endpoints. Five groups of five male rats each were administered orally for two consecutive days with doses of 100, 700 and 2000 mg/kg body weight of Kacip Fatimah extract dissolved in distilled water. Micronucleus preparation was obtained from bone marrow cells of the animals following standard protocols. No statistically significant increase in micronucleated polychromatic erythrocytes (MNPCEs) was observed at any dose level and sacrifice/harvest time point (24, 48 and 72h). However, a significant decrease in polychromatic erythrocytes/normochromatic erythrocytes (PCE:NCE) ratio was observed from the highest dose level (2000 mg/kg of body weight) at 48h harvest time point. In this study, we investigated the effect of Kacip Fatimah on mammalian bone marrow cells using micronuclei formation to assess the genotoxicity of the herb.
