Abstrakt: Objectives: This study evaluated the effects of Crude Methanol Extract of Adansonia digitata Fruit Pulp on Naja nigricollis Venom-Induce Toxicity in Wistar rats.
Methods: A . digitata was extracted using 70% methanol and median lethal dose (LD 50 ) of both the extract and venom were determined using the up-and-down method. Sixty Wistar rats were randomly assigned into 10 groups of 6 rats each and were administered with normal saline, venom only, venom + antivenom, 125 mg/kg, 250 mg/kg and 500 mg/kg crude methanol extract (CME) pre-envenomation, 125 mg/kg, 250 mg/kg and 500 mg/kg CME post-envenomation, and venom + antivenom + 250 mg/kg CME, respectively. Blood samples were collected 8-h post-envenomation in EDTA and plain sample bottles. Erythrocyte osmotic fragility (EOF) test was carried out on the EDTA blood samples while serum was harvested and used for Malondialdehyde (MDA) and Superoxide Dismutase (SOD) assays.
Results: LD 50 of the CME and venom was >5,000 mg/kg and 0.889 mg/kg, respectively. N . nigricollis -induced oxidative stress was evident in group B through increased % haemolysis, MDA and lowered SOD activities. The groups treated with antivenom only, 250 mg/kg CME post-envenomation and antivenom +250 mg/kg CME significantly (p<0.05) reduced EOF, MDA values and increased SOD. The CME revealed better ameliorative effect than protective via inhibition of EOF, MDA values and increased SOD activity.
Conclusions: The CME when administered singly showed more ameliorative properties and the combination of CME with antivenom for protection was not as effective as when compared to single administration.
