Ameliorative properties of aqueous extract of Ficus thonningii on erythrocyte osmotic fragility induced by acetaminophen in Rattus norvegicus

In vitro antioxidant and erythrocyte protecting activities by aqueous extract of Ficus thonningii leaves on blood cells were studied in acetaminophen treated rats. The extract was safe at limit dose of 5000 mg kg-1body weight. The extract demonstrated dose dependent antihemolytic effect at dose levels between 50 and 200 mg kg-1 body weight. The lowest antihemolytic effect was observed at dose level of 200 mg kg-1 body given the lowest percentage hemolysis of 10.53 ± 1.76%, whereas the highest percentage hemolysis at dose level of 50 mg kg-1 was 29.02 ± 7.45%. Hematology revealed erythrocytosis at dose levels of 100 and 200 mg kg-1 body weight. Hyper-globinemia and lymphocytopenia were observed at dose levels of 100 mg kg-1 and 200 mg kg-1, respectively. The extract effectively showed scavenging activity on a stable oxidative radical diphenylpicrylhydrazyl (DPPH) and a significant ferric reducing antioxidant power (FRAP) activity. The plausible erythrocyte membrane protective effect may be due to its free radical scavenging activity and hence the extract can be used to improve hematological parameters and ameliorate oxidative stress

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.

Sertoli cell tumor in a cryptorchid dog

Objective: This case report describes the surgical management of a clinical case of sertoli cell tumor in a Lhasa Apso breed of dog Materials and methods: A 4-year old sexually intact Lhasa apso was presented with complaints of alopecia, shivering, reduced appeteite and swelling of the inguinal region. The dog was subjected to thorough physical, Hematological, Histopathological and Radiographic evaluations. Results: The vital parameters were within normal values. Hematological analysis revealed anemia and thrombocytopenia as the common findings. Abdominal radiography showed a soft tissue mass in the inguinal region. Histopathology revealed testicular hypoplasia with poorly developed seminiferous tubule with no discernible lumen or spermatozoa and several proliferating sertoli cells on the lining of the basement membrane of the seminiferous tubules which is diagnostic of sertoli cell tumor. Decision to surgically excise the tumor was arrived at. The anesthetic protocol involved premedication with atropine sulphate dosed at 0.04 mg/kg bwt and xylazine dosed at 2 mg/kg bwt intramuscularly (IM). Anesthesia was induced and maintained with propofol dosed at 6 mg/kg bwt intravenously (IV). The tumor mass was surgically excised. Broad spectrum antibiotics (penstrep) and analgesic (pentazocine) were administered for 5 days IM. Conclusion: The condition of the dog improved remarkably and it was discharged on postoperative day 10. [J Adv Vet Anim Res 2017; 4(4.000): 394-398
