EVALUATION OF SUB-ACUTE TOXICITY OF THE HYDRO-METHANOL STEM BARK EXTRACT OF BURKEA AFRICANA IN ALBINO RATS

Objective: This study was designed to investigate the sub-acute toxicity profile of hydro-methanol extract of Burkea africana  (BA) stem bark in rats. Methods: The stem bark of BA was extracted by cold maceration using 80% methanol. Twenty female albino rats were randomly assigned into four groups of five rats each. Group 1 (only distilled water). Groups 2-4 received the extract (100, 200, and 400 mg/kg) orally, once daily for 28 days. The rats were observed for signs of toxicity and the bodyweight (b.wt) of rats taken weekly. Blood samples were collected on day 28 for hematology and serum chemistry. Visceral organs were harvested for organ-somatic index and histopathology. Results: There were no toxicity signs observed and no significant (p< 0.05) change in body weight but the pulmo-somatic index was significantly (p< 0.05) higher at 400 mg/kg compared with the control and other treated groups. Significant (p< 0.05) increase in PCV, RBC, and MCV and significant (p< 0.05) decrease in MCHC, Total WBC count, neutrophils and lymphocytes were observed. Also, there were significant (p< 0.05) decreases in ALT, total protein, globulin, total bilirubin of test groups when compared with the control group. Urea concentration of test groups significantly (p< 0.05) increased when compared with that of the control group. Conclusions: BA stem bark extract can be said to have no deleterious effect on erythrocyte, but rather serve to improve erythropoiesis and also has no overt toxic effect on the visceral organs. Also the extract may have immunosuppressive and oxidative tendencies on prolong use.                    Peer Review History: Received 12 January 2021; Revised 3 February; Accepted 25 February, Available online 15 March 2021 Academic Editor: Dr. DANIYAN Oluwatoyin Michael, Obafemi Awolowo University, ILE-IFE, Nigeria, [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: 5.0/10 Average Peer review marks at publication stage: 8.0/10 Reviewer(s) detail: Idoko Alexander, Caritas University, Enugu, Nigeria, [email protected] Taha A.I.
