ASSESSMENT EFFECT OF ALOE VERA, AZADIRACHTA INDICA AND MORINGA OLEIFERA AQUEOUS EXTRACTS ON CARBON TETRACHLORIDE-INDUCED HEPATOTOXICITY IN RATS

Objective: This experiment aims to investigate the hepatotherapeutic effect of Aloe vera (AV), Azadirachta indica (N), and Moringa oleifera (MO).Methods: Eighty albino rats have been divided into ten groups. The first group was fed on a basal diet while the second group was administered paraffin (10 ml/kg body weight) through gavage for four days. The third to the tenth groups received (5 ml/kg body weight) CCl4: liquid paraffin (2:1) for three days followed by (10 ml/kg body weight) CCl4: liquid paraffin (2:1) for one day through gavage. Group three kept without any treatment, other groups then received (AV) (60 mg/kg body weight), (MO) (200 mg/kg body weight), (N) (200 mg/kg body weight), bi-extract of (AV+N), bi-extracts of (AV+MO), bi-extract of (MO+N), and tri-extracts of (AV+N+MO) respectively for 36 d. The liver and blood were studied for hepatotoxicity and antioxidant indices.Results: Biochemical and histopathological analysis revealed that CCl4 elevated plasma liver enzymes (aspartate transaminase, alanine aminotransferase, and gamma glutamyl transferase). Carbon tetrachloride also caused an elevation in erythrocyte content of glutathione with a concomitant increase in the plasma malondialdehyde content, along with marked atrophy of hepatocytes. However, these effects were ameliorated by the treatment of rats with the different extracts.Conclusion: Results showed that administration of the aquatic extracts of Aloe vera, Neem, and Moringa (separately/mixedly) played a therapeutic role against CCl4-induced liver damage by improving liver enzyme activities, antioxidant blood parameters, and a liver histopathological picture of intoxicated rats.Keywords: Aloe vera, Azadirachta indica, Moringa oleifera, CCl4 hepatotoxicity, Antioxidant, Rat hepatocyte
