RESUMO
BACKGROUND: Exposure of animals to xenobiotics may or may not trigger adverse response at cellular levels. Aqueous extract of unripe Carica papaya is consumed by sickle cell patients as antisickling agent in Western Nigeria. AIM: This study was undertaken to investigate the effects of Carica papaya on certain organs in Wister albino rats exposed to aqueous extract of unripe Carica papaya. MATERIALS AND METHODS: Different doses of aqueous extract of unripe Carica papaya were administered orally daily for 42 days to six groups of rats. At the end of exposure, the animals were sacrificed and tissue sections were prepared from livers, kidneys, hearts and small intestines using standard techniques. RESULTS: Histopathological results showed that no pathological changes were observed in tissue sections of experimental animals when compared with tissue sections of the same organs in control animals. CONCLUSION: No pathological changes were elicited in the organs of rats exposed to aqueous extract of unripe Carica papaya.
