Objective: To investigate the haematopoetic effect of methanol extract of Nigerian honey bee
propolis in mice.
Methods: Fifteen white Albino mice were grouped into 3(A-C) of 5 animals each. Group A
mice serve as control group, while groups B and C received 300 and 600 mL/kg of honey bee
propolis respectively, for 21 days. The haematological parameters were determined using the
automated haematologic analyzer Sysmex kx21, (product of Sysmex Corporation, Japan) using
standard techniques. The data were analyzed using ANOVA and the level of significance was at
P < 0.05. Acute oral toxicity study was conducted to determine it's safety on acute exposure.
Results; Results showed significant (P < 0.05) dose dependent elevations in platelate
count, mean platelate volume, plateletecrit, platelete distribution weight, white blood cells,
granulocyte count, lymphocytes and mid cell total count. The extract however produce no
significantly (P > 0.05) alteration to the erythrocytic indices like red blood cells, haematocrite,
haemoglobin, mean corpuscular haemoglobin, mean corpuscular volume and red cell
distribution width, but increase mean corpuscular haemoglobin concentration in dose related
fashion. Acute oral toxicity showed the extract to be relatively safe at a high dose on acute
exposure. However, 21-days of treatment with the extract do neither increase nor decrease the
body weight of the mice.
Conclusions: Administration of methanol extract of Nigerian honey bee propolis in mice at
the doses investigated has brought about leucopoietic and thrombopoietic changes without any
significant effect on red blood cells and factors that relate to it, except for the mean corpuscular
haemoglobin concentration.
