Protective potentials of Annona muricata fruit pulp on etoposide-induced gastrointestinal toxicity in Wistar rats
Journal of Carcinogenesis
BACKGROUND: Mucositis, one of the devastating consequences of chemotherapy and also limits the efficacy of the treatment. At present, there are no antimucositic agents without side effects. Hence, there is a need for better adjuvant therapy using plant or food sources. Here, we have made an attempt to study the effect of Annona muricata (AM) fruit pulp on etoposide-induced mucositis. MATERIALS AND METHODS: The study was conducted at Central Research Laboratory, Kasturba Medical College, Mangalore. The effect of AM fruit pulp (100 mg and 200 mg/kg body weight) on etoposide-induced mucositis was studied in Wistar rats (n = 36) in comparison with normal and AM controls. Intestinal tissue was collected for histology and estimation of total antioxidants (TAO), glutathione (GSH), myeloperoxidase (MPO), and nitric oxide (NO) levels along with histological changes were studied. Statistical analysis was performed by one-way analysis of variance. RESULTS: TAO and GSH levels were found to be significantly high in the rats which received 200 mg of AM/kg body weight than 100 mg of AM/kg body weight when compared with etoposide control. The levels of inflammatory markers - MPO and NO - were found to be decreased (P < 0.001) in the animals received 200 mg/kg body weight of AM in comparison with etoposide group and lower dosage of AM pulp. Histology of intestine also showed a protective effect of AM (200 mg/kg body weight) against etoposide toxicity. CONCLUSION: The results show that AM fruit pulp has the capacity to act as antimucositic agent and also reduced inflammation.
