Serological studies revealed significant (<em>p</em>&lt;0.05) decrease in Alanine aminotransferase (ALT) at all doses tested, while at 140 mg/kg it caused a significant (<em>p</em>&lt;0.05) increase in Alkaline Phosphatase (ALP). At doses of 70 and 140 mg/kg there was a significant (<em>p</em>&lt;0.05) reduction in creatinine level. Histopathological studies on the liver showed moderate hepatocellular necrosis at doses of 35 and 70 mg/kg, while at 140 mg/kg there was intense hepatocellular necrosis,&nbsp; Kupffer cells and lymphocytes hyperplasia. The Kidney showed intense necrosis of tubules and glomerular necrosis with lymphocytes hyperplasia at all doses tested.&nbsp; The spleen also showed intense lymphocyte hyperplasia at all doses with sinusoidal congestion at the lowest dose of 35 mg/kg. The heart showed slight necrosis of cardiac muscle cells at all doses with blood congestion at 35 and 70mg/kg body weight.</p> <p><strong>Conclusion:</strong> The study indicates that prolong use of the extract in the management of disease conditions may be associated with some adverse effect of some vital organs.</p> Abubakar Bilyamini Mu’azu Yusif Bello Baba Adamu Idris Matinja ##submission.copyrightStatement## 2020-06-17 2020-06-17 1 9 10.9734/ajrb/2020/v6i430123 Ameliorative Effect of the Methanol Extract of Napoleonae imperialis Leaves against Methotrexate-induced Renal Damage in Albino Rats <p><strong>Aim:</strong> This study was aimed to evaluate the effect of methanol extract of <em>Napoleonae imperialis leaves</em> against methotrexate renal damage in albino rats.</p> <p><strong>Methodology:</strong> 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,</p> <p><strong>Results:</strong> From the result obtained, there was a significant (p&lt; 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<sup>+</sup>), and a significant increase (p&lt; 0.05) in K<sup>+</sup> and Cl<sup>-</sup>. Also there was a significant (p&lt; 0.05) decrease in (Urea, Creatinine, and Na<sup>+</sup>) in comparison with the control groups and the group that received the extract only (500 mg/kg b.wt), and a significant increase (p&lt; 0.05) in (K<sup>+</sup> and Na<sup>+</sup>).</p> <p><strong>Conclusion:</strong> The study indicates that the methanol extract of <em>Napoleonae imperialis leaves </em>may have exerted renal functioning effects in albino rats, and may also be used pharmacologically in the management of organ toxicity.</p> O.

The crude extract and isolated metabolites were used to evaluate its potential anti-cancer activity which was compared to methotrexate (MTX) in cervical cancer cell line. The present study involved in using crude mangosteen (CM), γ-mangostin (γ-M), isopropyl mangostin (IPM) and Di-<em>O</em>-methyl mangostin (DMM) against the standard anti-neoplastic drug MTX. Cell viability and cytotoxicity by lactate dehydrogenase (LDH) were assessed. Analysis of DNA fragmentation and clonogenic assay further supports the anti-cancer activity of the drugs in <em>HeLa </em>cells. The IC<sub>50</sub> value for CM, γ-M, DMM, IPM and MTX were 13.4µg, 34.84µM, 15.57µM 5.3µM and 16.05µM respectively observed in the present study. This study suggests that the <em>G. mangostana </em>and its derivatives have potential anti-cancer activity an <em>in vitro</em> study in cervical cancer.</p> S. V. Kirthanashri N. Ramesh Kumar S.
