Abstract

Cytogenetic study was conducted to test the effects of three treatments (weight by volume): 1%, 3% and 5% of narra (Plerocarpus indicus Willd.) bark extract on in vitro cultures of human leukocytes from five male blood donors. Statistical analysis using repeated measure design and Duncan's Multiple Range Test (DMRT) showed that Giemsa-stained cells exhibited significant differences in mitotic indices. With the increasing concentrations of treatments was the corresponding significant decreasing trend of mean mitotic index: 0.084 (1%), 0.059 (3%), 0.032 (5%) while the Control was 0.12. Otherwise is true of the chromosomal aberrations wherein the increasing concentrations of treatments corresponding with significantly increasing frequencies of highly condensed chromosomes 0.027 (1%), 0.25 (3%), and 0.48 (5%), the Control was 0.19, chromosome gaps 0.12 (1%), 0.23 (3%) and 0.30 (5%), the Control was 0.10, breaks 0.19 (1%), 0.31 (3%) and 0.28 (5%), the Control was 0.096 and loosely paired sister chromatids 0.15 (1%), 0.15 (3%) and 0.23 (5%), the Control was 0.062. The control exhibited spontaneous chromosomal aberrations.
