Viscum album prevents haematological changes, electrolyte imbalance, changes in liver function enzymes and histological alterations in some selected tissues in cadmium chloride-intoxicated rats.

ABSTRACT

Background: The use of Viscum album to treat different diseases is popular in the practise of alternative medicine. We investigated the ability of the aqueous extract of V. album to protect against the toxic effects of cadmium. Methods: Thirty rats used for the experiment were treated as follows; Group 1 - no cadmium or extract. Group 2-10 mg/kg body weight of cadmium chloride. Group 3-10 mg/kg body weight of cadmium chloride and 200 mg/kg body weight of aqueous extract of V. album. Group 4-10 mg/kg body weight of cadmium chloride and 400 mg/kg body weight of aqueous extract of V. album. Group 5-10 mg/kg body weight of cadmium chloride with 800 mg/kg body weight of aqueous extract of V. album. Group 6-10 mg/kg body weight of cadmium chloride and atorvastatin (100 mg/kg body weight). Results: Apart from WBC and platelets, other haematological parameters and electrolytes, urea and creatinine levels were not significantly affected by the administration of cadmium chloride along with the aqueous extract of V. album. Treatment with the extract caused significant decreases in the hepatosomatic index, cardiosomatic index, and increase in renosomatic index of the test rats. It also resulted in significant (P < 0.05) decrease in AST level. Histological report also shows that treatment with the extract restored the normal myocardium and vascular architecture of the heart, normal portal and vascular architecture of the liver and normal glomerular and tubular architecture of the kidney, in the cadmium-intoxicated experimental rats. Conclusion: V. album protects against the toxic effects of cadmium chloride.
