Abstract

Effect of whole ethanolic and selective solvent extracts of C. portoricensis plant was carried out in wistar rats to ascertain their efficacy in ameliorating or attenuating the haemotoxicity of venom of carpet viper. A total of 30 wistar rats were used, divided into 6 rats per group of control, venom, venom/flavonoid-rich, venom/polyphenol-rich and venom/whole ethanolic extracts. The control was given nothing while the other groups were given 200μg venom/rat and 0.5 ml 100mg/100g body weight (b.w.) of rat as “anti-dote” concentration. This “antidote” was given intramuscularly 4-6 hours after the administration of the venom. The result obtained showed significant increase (P<0.05) in the haemoglobin concentration, red blood cell count, mean corpuscular volume, white blood cell count especially in neutrophils and marked decrease (P<0.05) in platelet parameters. These findings suggest that whole ethanolic and selective solvent extract of C. portoricensis may be effective in ameliorating and indeed reversing the haemotoxicity occasioned by carpet viper haemotoxin in wistar rats.
