Synergistic effect of combined multiple plants extract on some blood cell indices of diabetic rats

Abstract

This study evaluated the impact of combined therapy of multiple plants extract of Cnestis ferruginea, Xylopia aethiopica, Palisota hirsuta, Scleria sp., Napoleona imperialis, Dialium guineense, Combretum racemosun, Heterotis rotundifolia leaves, stem of Sphenocentrum jollynum stem, and root of Uvaria chamae on blood cell indices of diabetics. Female Wistar rats of 40 – 50 g and fifty-four (54) in number were used for this study. They were assembled into 6 groups of 9 rats each. Group I served as the normal control (NC) while the remaining five groups were induced with diabetes type 2 using high-fat diet (HFD) for 8 weeks and asingle dose intraperitoneal injection of streptozotocin at 35 mg/kg body weight. Group II was the diabetic control (DC) while the other groups (III, IV, V & VI) were orally administered 7.2 mg/kg metformin and the cocktail extract at three different concentrations of 500 mg/kg, 250 mg/kg, and 100 mg/kg respectively. Diabetes was established after HFD and STZ administration. Blood cell indices such as platelets, red blood cells (RBCs), white blood cells (WBCs) and differentials were evaluated after twelve weeks of treatment using a hematology auto- analyzer. Results obtained showed that the diabetic control group recorded lower platelets, RBC, WBC, neutrophil and eosinophil as well as higher lymphocyte and monocyte when compared to the groups administered the cocktail extract and other experimental groups. This study revealed that the combined therapy of the multiple plants extract has positive effect on blood cell indices and can be adopted as a blood cell boosting agent.
