Abstract Background Exposure to arsenic orchestrates a myriad of noxious health effects, including cancer. Different parts of Irvingia gabonensis are used as herbal remedies in traditional medicine. In this study, the comparative effects of the ethanol leaf (ELEIG) and stem bark extracts (ESEIG) of Irvingia gabonensis on sodium arsenite (SA)-induced lipid profile disturbances in Wistar rats were investigated. Methods Fifty five Wistar rats weighing between 100 g and 179 g were distributed into eleven groups (n=5). Group 1 (control) received feed and water ad libitum. Group 2 received SA at a dose of 4.1 mg/kg body weight (kgbw) for 14 days. Groups 3–11 were treated with the extracts with or without SA. Treatment was done by oral intubation for 14 days. Serum concentrations of total cholesterol (TC), triacylglycerol (TAG), high density lipoprotein cholesterol (HDL-c), low density lipoprotein cholesterol (LDL-c), very low density lipoprotein cholesterol (VLDL-c), total lipids (TL) and atherogenic index of plasma (AIP) were used to determine the lipid profile effects of the extracts. Results Exposure to SA caused significant (p ˂ 0.05) increases in all assayed parameters, relative to control. Post-treatment and simultaneous treatment with ELEIG and ESEIG mitigated the effects of SA. In addition, ELEIG alone at various doses produced results comparable with control values. However, ESEIG alone caused significant (p ˂ 0.05) increases in all assayed parameters, relative to control. Conclusion These results show that ELEIG and ESEIG ameliorate SA-induced lipid profile disturbances in Wistar rats. However, long-term administration of ESEIG alone may be discouraged.

Objective: Many plants are consumed as food by humans for growth and survival, but a large number of these plants have not been tested for toxicity potential. Repeated consumption of such plants could lead to accumulation of toxic chemicals in the body and cause health-related problems. Irvingia wombolu kernel is widely consumed by many ethnic groups in Nigeria and some other African countries. The toxicity potentials of Irvingia wombolu kernel extract (IWKE) on the kidney and liver of rats was evaluated in this study. Methods: Three groups of Wistar rats were fed orally with IWKE (50, 100, and 200 mg/kg b.w) daily for 28 days. The fourth group which is the control was treated with distilled water (10 ml/kg b.w) for the same period.  The rats were sacrificed on the 29th day, and blood samples, kidney and liver were harvested for analyses. Serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total protein, albumin, bilirubin, creatinine, and urea were determined. Kidney and liver sections were examined for histopathological changes. Data were subjected to Student’s t-test for statistical analysis. Results: Serum levels of creatinine and urea were not significantly altered in the IWKE-treated rats compared with the control. At 200 mg/kg b.w, the extract significantly increased (p<0.05) serum levels of ALT, AST, total bilirubin, total protein, and albumin compared with the control. Significant distortions were observed in the liver sections of rats treated with 200 mg/kg b.w IWKE compared with control, but the structure of the kidney section of IWKE-treated rats was not significantly different from the control. Conclusion: The results showed that repeated ingestion of Irvingia wombolu kernel at a dose of 200 mg/kg b.w for 28 days induced liver damage, but does not significantly affect renal function.                       Peer Review History: Received: 9 September 2021; Revised: 12 October; Accepted: 27 October, Available online: 15 November 2021 Academic Editor:  Dr. Ali Abdullah Al-yahawi, Al-Razi university, Department of Pharmacy, Yemen, [email protected] UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.  Received file:                Reviewer's Comments: Average Peer review marks at initial stage: 6.0/10 Average Peer review marks at publication stage: 7.5/10 Reviewers: Dr. Sangeetha Arullappan, Universiti Tunku Abdul Rahman, Malaysia, [email protected] Ahmad Najib, Universitas Muslim Indonesia, Makassar, Indonesia, [email protected] Taha A.I.

Abstract Background Estrogen deficiency in postmenopausal period causes severe neuroendocrine changes in brain which influences memory and other nervous functions. Anthocleista schweinfurthii is used traditionally to treat female infertility and menopause related symptoms. This study was performed to investigate the potential neuroprotective effects of aqueous extract of Anthocleista schweinfurthii on brain in a postmenopause-like model of ovariectomized Wistar rats. Methods Thirty animals were sham-operated or ovariectomized (Ovx) 84 days after surgery, six groups of five rats each were daily treated orally during 28 days with: distilled water for groups 1 (sham-operated) and 2 (Ovx), estradiol valerate (group 3) and the three doses of extracts {groups 4, 5 and 6 (Ovx)}. Biochemical and histological evaluations focused on brain. Results Compared to sham-operated control, ovariectomy decreased total protein levels in brain (p<0.01) which was increased by plant extract at the dose of 300 mg/kg (p<0.05), underlying its anabolic properties. Ovariectomy significantly decreased magnesium levels in brain (p<0.001). Anthocleista schweinfurthii increased significantly magnesium levels (p<0.01), showing its capacity to act on synaptic conduction. Ovariectomy induced oxidative stress by increasing malondialdehyde levels (p<0.05) and decreasing reduced glutathione levels (p<0.05) in brain. The plant extract exhibited antioxidative activity by reducing malondialdehyde levels and increasing glutathione levels in brain. Damage in brain structure which was caused by ovariectomy disappeared following the treatment. Conclusions Results suggest that Anthocleista schweinfurthii may have neuroprotective effects in Ovx Wistar rats by increasing total protein, magnesium levels and reducing oxidative stress in brain.

AbstractThe use of traditional medicinal plants to treat various diseases is common in Sub-Saharan African countries, including Cameroon.We evaluated the effects of the dichloromethane (DCM) and methanol (MeOH) soluble fractions ofData showed a significant decrease (p<0.05) in the wiring-touch frequency, mount frequency, intromission frequency, ejaculatory frequency, penile-licking frequency, and computed indices of sexual behavior, throughout the experimental period, as well as a significant increase (p<0.001) in mount, intromission, and ejaculatory latencies as well as post-ejaculatory interval. Moreover, we observed a significant decrease (p<0.05) in the androgen-dependent sexual parameters evaluated. The DCM extract did not induce significant effects on the assessed parameters.These results suggest that long-term exposure to the estrogenic MeOH fraction of
