  • Activity of Adansonia digitata on biochemical and hematological changes in established Plasmodium berghei -infected mice
    Comparative Clinical Pathology, 2019
    Co-Authors: Akinwunmi O. Adeoye, Clement O. Bewaji
    Abstract:

    The intra-erythrocytic lifestyle of malaria parasite contributes an additional oxidative burden, resulting from digestion of the host hemoglobin as the parasite grows within the infected cell. This study evaluated the efficacy of Adansonia digitata stem bark extract on hematological and renal changes in established Plasmodium berghei infection in mice. Albino wistar mice were used in the study. The mice were transfected intraperitonially with an inoculum size of l × 107 of chloroquine susceptible strain of Plasmodium berghei-infected erythrocytes. Percentage chemosupression and packed cell volume (PCV) were determined. The antiplasmodium effects of the extracts were investigated by measuring the hemoglobin (Hb) content, white blood cell (WBC) count, and cell differentials. Severity of malaria was determined by measuring the serum creatinine, urea, and uric acid concentrations. An essential biomarker of malaria-associated disturbance in mineral homeostasis was determined by measuring the electrolyte concentrations. Administration of the extracts had effect on the growth of Plasmodium berghei parasite in mice. The extracts showed a significant decrease in percentage parasitemia at the two doses and a significant dose-dependent increase in PCV, percentage chemosupression when administered after established infection. There was a significant decrease in hemoglobin content, neutrophil, lymphocyte, and mean corpuscular hemoglobin concentration (MCHC) in the control group following Plasmodium berghei infection. The extract significantly reduced the WBC, platelet, monocyte count, mean corpuscular hemoglobin (MCH), and mean cell volume (MCV). Administration of the extract after established infection significantly reduced the creatinine, Na+, K+, Ca2+, and Cl− concentrations. The concentrations of urea, uric acid, and Mg2+ were significantly higher in control mice. Our study suggests that Adansonia digitata has antimalarial activity and modulates biochemical and hematological changes in established Plasmodium berghei infection.

  • Chemopreventive and remediation effect of Adansonia digitata L. Baobab (Bombacaceae) stem bark extracts in mouse model malaria.
    Journal of ethnopharmacology, 2017
    Co-Authors: Akinwunmi O. Adeoye, Clement O. Bewaji
    Abstract:

    Abstract Ethnopharmacological relevance Adansonia digitata L . Baobab (Bombacaceae) solvent extracts have been reported to possess medicinal properties and are currently been used traditionally for the treatment of malaria and several other diseases and infection; however few reports exist in literature that provides supportive scientific evidence in favour of its medicinal use. Aim of the study This study investigated the efficacy of Adansonia digitata stem bark extract in offering protection against experimental malaria and also examined its remediation effect when administered after established infection. Materials and methods Weanling albino mice were used in the study. The mice were transfected intraperitonially with an inoculums size of 1× 10 7 of chloroquine susceptible strain of plasmodium berghei infected erythrocytes. Mechanisms of action of the extract were investigated by measuring the degree of tissue peroxidation and tissue antioxidant status. Severity of malaria was determined by measuring the serum C-reactive protein (CRP), tumor necrnecrosis factor-alpha (TNF-α), and serum and tissue Alkaline phosphosphatase (ALP) activity. Results There was a significant increase in serum CRP, TNF-α concentrations and serum and tissue ALP activity in the control mice following Plasmodium berghei infection. All the treatment had effect on the growth of Plasmodium berghei parasites in mice. The extracts showed a significant dose dependent increase packed cell volume (PCV), percentage chemosupression/clearance and a significant decrease in percentage parasitemia at the two doses when administered after established infection. Methanolic extract (MEAD) at 400 mg/kg exhibited the highest chemosupressive activity. The extract significantly reduced the degree of tissue peroxidation, increased the level of reduced glutathione (GSH), catalase and superoxide dismutase activity. Administration of the extract after established infection reduced serum CRP and TNF-α concentrations and serum and tissue ALP activity. Conclusion Our study suggests that Adansonia digitata protects against Plasmodium berghei induced-malaria, and that administration of the extract after established infection reduced malaria progression.

  • Studies on germination of Adansonia digitata seeds
    The Journal of Agricultural Science, 1991
    Co-Authors: G. J. Esenowo
    Abstract:

    Dormancy in seeds of Adansonia digitata (L.) can be attributed partly to the testa and partly to the pulp. Several methods, such as wet heat treatment, total or partial seed decoating and scarification of seeds with concentrated acids, herbicides, fungicides and growth regulators, were tested in 1988 and 1989 to break dormancy. The most effective was scarification with HNO3 or H2SO4, which gave 86 and 98% germination, respectively, while total decoating, partial decoating, wet heat treatment and ethrel gave 85, 80, 75 and 70%, respectively. Seeds treated with herbicides and fungicides did not germinate. Inhibition of germination caused by the pulp was overcome by thorough washing of seeds and soaking in water for 3 days.
