Aim: This study was aimed to evaluate the effect of methanol extract of Napoleonae imperialis leaves against methotrexate renal damage in albino rats. Methodology: Thirty (30) male albino rats of mean weight 130 g were used for this study. The animals for the study were grouped into five (5) of six (6) rats each. Group A (normal control) received feed and water only and Group B (positive control) was induced with methotrexate without treatment. Test groups (C and D) were orally given 250 mg and 500 mg/kg b.wt of leaves extract, and group E was orally given the extract only (500 mg/kg b.wt) respectively for 14 days. All the rats used in this study were initially subjected to renal damage using 0.5 ml/kg of methotrexate except the normal control group. The rats were sacrificed after 14 days and the blood samples were collected for biochemical analysis, Results: From the result obtained, there was a significant (p< 0.05) decrease in the groups that received 250 mg/kg and 500 mg/kg b.wt of the plant extract in (Urea, Creatinine and Na+), and a significant increase (p< 0.05) in K+ and Cl-. Also there was a significant (p< 0.05) decrease in (Urea, Creatinine, and Na+) in comparison with the control groups and the group that received the extract only (500 mg/kg b.wt), and a significant increase (p< 0.05) in (K+ and Na+). Conclusion: The study indicates that the methanol extract of Napoleonae imperialis leaves may have exerted renal functioning effects in albino rats, and may also be used pharmacologically in the management of organ toxicity.

The anti-inflammatory and hepatoprotective properties of methanol extract of Arachis hypogea leaves were studied. At 400 mg/kg, the extract significantly suppressed the development of hind paw oedema induced by egg albumin, which compares favorably with a standard anti–inflammatory drug aspirin (acetylsalicylate) which at 100 mg/kg inhibits egg-albumin induced rat paw oedema. It was observed that the extract significantly inhibited platelet aggregation in a dose dependent fashion. At 0.6 and 0.7 mg/ml the percentage inhibition of platelet aggregation was observed to be 53.13 and 68.75% which compare closely to the standard drug indomethacin at 0.2 and 0.4 mg/ml which was found to be 53.13 and 65.63% respectively. Similarly, there was also an observable decrease in the activity of prostaglandin synthase which was dosage dependent at 0.1, 0.5 and 1 mg/ml, the percentage enzyme activity was 65, 70 and 95% respectively. Also, at 1 and 4 mg/ml of indomethacin, the percentage enzyme activity was 94.75 and 99.25% respectively. There was non-significant difference (P
