RESUMO
OBJECTIVES: We aimed to examine the potential protective effects of Iraqi H. tiliaceus L. chloroform leaves extract on DEN-induced HCC in male Wistar Albino rats. METHODS: Rats were assigned to four groups, six in each group. Group I: rats were administered a daily oral dose of 1â¯mL/kg/day of distilled water. Group II: rats were intraperitoneally injected with 70â¯mg/kg DEN once per week for 10 consecutive weeks. Group III: rats received 250â¯mg/kg of chloroform leaves extract. Groups IV: the rats were administered 500â¯mg/kg of chloroform leaves extract, along with their food, for five days per week over 20 weeks, with a subsequent dose of DEN once per week for 10 consecutive weeks. RESULTS: The results indicate that the extract demonstrated a significant reduction (p<0.05) in oxidative stress, pro-inflammatory mediators, and HCC parameters, the extract also had a beneficial effect on liver function tests, and there was a significant elevation (p<0.05) of antioxidant parameters in a dose-dependent manner. CONCLUSIONS: This study supports the protective properties of the chloroform extract of Iraqi H. tiliaceus L. leaves in HCC.

Obesity is a world health concern and a serious risk factor for several chronic diseases. Hibiscus tiliaceus is a plant with reported anti-obesity properties. However, the preclinical anti-obesity effect of ethanolic extract of Iraqi Hibiscus tiliaceus has not been studied yet. This study aimed to evaluate the preclinical anti-obesity properties of Iraqi Hibiscus tiliaceus extract, alone or in combination with orlistat, on high-fat diet-induced obesity in male rats. Male rats were divided into five groups: control, induction, ethanolic extract of Iraqi Hibiscus tiliaceus (250 mg/kg and 500 mg/kg), orlistat (Xenical) alone (10 mg/kg), and a combination of the extract (250 mg/kg) with Xenical. The rats were fed a high-fat diet to induce obesity, and treatments were given orally for 8 weeks. Body weight, food intake, serum lipid profile, and liver enzymes were measured. Administration of ethanolic extract of Iraqi Hibiscus tiliaceus (250 mg/kg and 500 mg/kg), Xenical alone (10 mg/kg), and combination with the extract (250 mg/kg) for 8 weeks significantly reduced body weight, food intake, serum triglycerides, total cholesterol, low-density lipoprotein cholesterol, and liver enzymes (aspartate transaminase and alanine transaminase) when compared to the induction group. The ethanolic extract of Iraqi Hibiscus tiliaceus showed anti-obesity effects and could be a potential therapeutic agent in managing obesity. However, further studies are needed to evaluate its clinical efficacy and safety.
