Hepatoprotective effect of methanol extract of Agave americana leaves on paracetamol induced hepatotoxicity in Wistar albino rats

Investigating the hepato-protective properties of chamomile oil and olive leaves extracts against ribociclib-induced hepatotoxicity

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.

Ethanolic Extract of Mangifera indica Protects against CCl4-Induced Hepatotoxicity via Antioxidant Capabilities in Albino Rats

Objective

To investigate the antioxidant and hepatoprotective effects of ethanolic Mangifera indica (M. indica) seed extract on carbon tetrachloride (CCl4)-induced hepatotoxicity in albino rats.

Methods

Forty-eight albino rats weighing (100-150 g) were used for hepatoprotective and toxicity experiments. Antioxidant activity was determined using the 2, 2-diphenyl-1-picrylhydrazyl (DPPH) assay. The toxicity of M. indica seeds on the liver was evaluated by examining wellness parameters, body weight, and liver histological sections. The protective effects of 50 mg/kg and 100 mg/kg of seed extract on CCl4-induced hepatotoxicity were investigated by evaluating hematological, renal, and liver function parameters, body weight, and liver histological sections.

Results

The antioxidant activity of the M. indica ethanolic extract was (92 ± 0.03 RSA %) compared with (91 ± 0.01 RSA %) of propyl gallate, and the IC50 was (8.3 ± 0.01 µg/ml) and (14.1 ± 0.01 µg/ml). No changes were observed in the health indicators, body weights, and liver histological sections following oral administration of 50 mg/kg and 100 mg/kg of M. indica seed extracts. Treatment with M. indica seed extract significantly reduced alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), blood sugar, and urea levels compared with those in the CCl4-treated group.

Conclusion

The IC50 of the M. indica ethanolic extract was 8.3 µg/ml, and the M. indica extract is a potential source of natural antioxidants that protect against CCl4-induced hepatotoxicity.

Evaluation of the Hepatoprotective Properties of Traditional Formulations Based on Cochlospermum tinctorium Used in Benin

Hepatic diseases represent a public health problem. Among the approaches to their management is the use of traditional treatments based on the use of medicinal plants. In Benin, several recipes based on Cochlospermum tinctorium are used in the treatment of hepatitis without a real scientific basis. This study aimed to evaluate the hepatoprotective effects and acute oral toxicity of 10 of these recipes. The variables studied were the variety of C. tinctorium (wild form vs. cultivated form), the species associated with C. tinctorium (Combretum micranthum vs. Chromolaena odorata), and the proportion of C. tinctorium in the recipe (1; 4/5; 1/2). The hepatoprotective effect of these extracts at doses of 100, 200, and 400 mg/kg/bw was evaluated in Wistar rats subjected to hepatotoxicity induction through the administration of 5 g/kg of paracetamol. Acute oral toxicity was assessed following the OECD 423 protocol. The results revealed an absence of acute oral toxicity for the 10 recipes. The hepatoprotective tests conducted indicated that the hepatoprotective effect of C. tinctorium is dose dependent. The wild variety of C. tinctorium had a better hepatoprotective effect than the cultivated one. The association with C. micranthum enhances the hepatoprotective effect of C. tinctorium, unlike that with C. odorata. This study emphasizes that the combination of C. tinctorium with C. micranthum in the treatment of hepatitis is scientifically justified and it exhibits a dose-dependent hepatoprotective effect.

Natural Products for Acetaminophen-Induced Acute Liver Injury: A Review

The liver plays a vital role in metabolism, synthesis, and detoxification, but it is susceptible to damage from various factors such as viral infections, drug reactions, excessive alcohol consumption, and autoimmune diseases. This susceptibility is particularly problematic for patients requiring medication, as drug-induced liver injury often leads to underestimation, misdiagnosis, and difficulties in treatment. Acetaminophen (APAP) is a widely used and safe drug in therapeutic doses but can cause liver toxicity when taken in excessive amounts. This study aimed to investigate the hepatotoxicity of APAP and explore potential treatment strategies using a mouse model of APAP-induced liver injury. The study involved the evaluation of various natural products for their therapeutic potential. The findings revealed that natural products demonstrated promising hepatoprotective effects, potentially alleviating liver damage and improving liver function through various mechanisms such as oxidative stress and inflammation, which cause changes in signaling pathways. These results underscore the importance of exploring novel treatment options for drug-induced liver injury, suggesting that further research in this area could lead to the development of effective preventive and therapeutic interventions, ultimately benefiting patients with liver injury caused by medicine.
