ABSTRACT
pPalmyrah palm (Borassus flabellifer) is widely consumed by people in certain tropical countries. The incidence of human malignant lymphomas, mutagenicity and toxicity in rats and bacteria encouraged us to study the potency of palmyrah crude aqueous extracts in inducing sister-chromatid exchanges (SCEs) in human blood lymphocytes in vitro. The extracts induced SCEs in a dose-related manner in both females and males. These effects apparently showed no consistency between batches. This result may be due to the intrinsic variation of different donors in their response to the induction of SCEs by palmyrah extracts. SCE frequency was proportional to chromosome length and SCEs at the centromeric region showed no difficulty in being scored. Concerning methods of short-term cytogenetic testing for detecting mutagenic and carcinogenic chemicals, we found that the SCE test was not more sensitive than the classic chromosome-breakage test.
