Investigando as propriedades hepatoprotetoras do óleo de camomila e extratos de folhas de oliveira contra a hepatotoxicidade induzida por ribociclibe

Abstract

Abstract A new approach to overcome or reduce these toxicities is by using antioxidants. Ribociclib, a CDK4/6 inhibitor used in the treatment of breast cancer, has been linked to hepatotoxicity and may contribute to the development of Hepatocellular carcinoma in rats. This Study aims to assess hepatoprotective effect of chamomile oil and olive leaf extracts against ribociclib-induced Hepatotoxicity in rats. A total of 40 adult male albino rats aged 9-10 weeks were utilized in this experiment. These rats were divided into four groups, (N=10). Group A (control) comprised normal rats administered 1 ml (10 ml/kg/day) of normal saline daily. Conversely, group B rats were administered 5 mg/kg Ribociclib (n = 10), while group C was administered 5 mg/kg Ribociclib with a 500 mg/kg/day dose of chamomile oil. Group D was given 5 mg \kg Ribociclib in combination with 200 mg/kg/day of olive leaves. After the trial, the animals were sacrificed, blood samples were collected for biochemical tests, and the liver tissue was processed for histological examination. The results of histology, and biochemistry parameter analysis, indicated that co-administration of Ribociclib and chamomile oil plays a decisive role in mitigating the hepatotoxicity result from Ribociclib-induced liver injuries in rats as demonstrated by histological and biochemical parameters.The levels of cholesterol and LDL in the blood were significantly lower (P < 0.01) after administering chamomile oil compared to the control group. The results of the current study demonstrated that the simultaneous use of chamomile oil and olive leaf extract significantly reduced the liver damage caused by Ribociclib and improved the lipid profile in Albino rats. Additionally, the use of chamomile extract notably lowered urea levels (p < 0.01), indicating a protective effect on the kidneys.
