AbstractBackgroundIn traditional medicine, Allium cepa Linnaeus is used for the treatment of several disease conditions. Whilst reports abound on the effects of several cultivars of A. cepa L on biochemical parameters, similar information on the red cultivar is scarce. This study examines the effects of the methanol extract of the red cultivar A. cepa L on some serum biochemical parameters in experimental Wistar rats.Materials and methodsFifty-five Wistar rats were divided into three groups (A, B and C), which include 25, 25 and 5 rats, respectively. The rats in Groups A and B were sub-divided into 5 groups of 5 rats. Each rat was administered a certain dose of methanol extract of the red cultivar A. cepa L for 14 days (Group A) or 28 days (Group B). Group C rats served as the control and were administered with distilled water (10 mL/kg).ResultsA. cepa L administration resulted in dyslipidaemia, hyponatremia, hypokalaemia and hyperchloraemia; a significant (p < 0.05) decrease in hepatic enzymes and a significant (p < 0.05) increase in serum bicarbonate, bilirubin and its fractions.ConclusionsThese biochemical results indicate that the excessive and prolonged medicinal consumption of A. cepa L products beyond 7 days may induce moderate hepatic injury and mild renal dysfunction and may complicate disease conditions, such as hypertension and diabetes. Thus, in order to minimize its toxic effects, it is recommended that A. cepa L products should not be used for more than seven consecutive days or beyond a dosage of 90 mg/kg.

Background: Efavirenz is a drug used in combination as highly active antiretroviral therapy (HAART) used for the treatment of human immunodeficiency virus (HIV).Aims and Objectives: To investigate the effects of Efavirenz and vitamin E on the histopathology and biochemical parameters in the liver of Wistar rats.Materials and Methods: Twenty five Wistar rats were divided into fi ve groups. Group A were administered with 1 ml of distil water; group B animals were administered with 8.57 mg/kg Efavirenz, group C were administered with 17.14 mg/kg Efavirenz; group D were administered with 8.57 mg/kg, Efavirenz and 14.82 mg/kg Vitamin E, and group E were administered with 14.82 mg/kg Vitamin E for 32 days. On day 33, the rats were sacrificed using chloroform inhalation method. The liver were excised, routinely processed, stained using haematoxylin and eosin method, and viewed in DPX medium under light microscope. Blood samples from the rats were collected and then centrifuged after 30 minutes to obtain the serum for analysis of aspartate amino transaminase (AST), alanine amino transaminase (ALT), alkaline phosphatase (ALP), and total bilirubin (TB).Results: The liver of Wistar rats administered with Efavirenz, showed distortions with various degree of vacoulations, dilatation of sinusoidal spaces and nuclei pyknoctic changes. In the group where Efavirenz was combined with vitamin E this changes were ameliorated. This also agreed with the biochemical changes which showed significant levels of increase in AST and ALT in Efavirenz groups, this changes were also ameliorated in the group that Efavirenz was combined with vitamin E.Conclusion: Efavirenz administration can damage the liver, vitamin E can ameliorate this effect, therefore Vitamin E should be prescribed for patients on Efavirenz administration.Asian Journal of Medical Sciences Vol.7(5) 2016 81-86

In the search for medicinal plants that will provide ameliorative measure to patients with anaemic disorders. The methanol extract of O. gratissimum leaf was administered to Wistar rats for its effect on haematological profile. Twenty-eight (28) male Wistar rats ranging from 180-200g was randomly picked and placed into plastic cages labeled A-D. Group A served as the control group while groups B-D was the test groups. The  animals in group A was administered with distilled water orally by gavage. Group B were administered 50mg/ kg body weight of methanol extract of O. gratissimum, group C were administered with 100mg/kg bodyweight while group D were administered with 200mg/body of methanol extract of O. gratissimum for 14 days. Blood was collected from all the test rats and control by cardiac puncture using disposable syringe and needle then dispensed into tubes containing EDTA. The extract displayed a significant increase (p<0.05) in RBCs, Hb, PCV and platelet counts. More so, the  extract produced no significant (p>0.05)difference in MCV, MCH, MCHC and RDW WBC counts when compared with the normal control .Therefore, it will be logical to conclude that the extract of O. gratissimum might be a panacea in the management of anaemic conditions when properly harnessed due to its erythropoietic, haematopoietic and thrombopoietic effect. Keywords: Anaemia, erythropoietic, haematopoietic, thrombopoietic and phytochemicals.

PURPOSE: To assess the effects of Roux-en-Y jejunal limb length on gastric emptying and enterogastric reflux. METHODS: Seventy male Wistar rats were submitted to antrectomy with Roux-en-Y reconstruction and then were divided into two groups of 35 animals. Group A, short limb (7.5 cm) and Group B, standard limb (15 cm). Group A and B were subdivided into five subgroups each in order to study enterogastric reflux at 30 and 60 minutes and to evaluate gastric emptying at 5, 10 and 15 minutes. In order to measure gastric emptying and enterogastric reflux, radiotracers 99m Tc-Phytate and 99m Tc-DISIDA were respectively used. RESULTS: For gastric emptying, the radiotracer concentration was lower in Group A than in Group B after five minutes. The enterogastric reflux was present, but there were no significant differences between enterogastric reflux indexes concerning both A and B Groups. CONCLUSION: A standard Roux limb, besides being unable to protect the stomach from the enterogastric reflux, may become a functional barrier for gastric emptying.

ABSTRACT Background: Researches on Chagas disease still use several animals and rats, due to size and susceptibility were preferred by many authors. Aim: To develop an experimental model of megacolon in rats inoculated with the strain Y of Trypanosoma cruzi. Methods: Thirty male Wistar rats were distributed in three groups inoculated with different inoculants: Group A: 600000, Group B: 1000000 and Group C: 1500000 blood trypomastigotes of T. cruzi. Animals were sedated intramuscularly at zero inoculation time (T0) and 60 days after inoculation (T60), to perform the barium enema in order to evaluate the dilatation of the different segments of colon in a comparative study of the measurements obtained, using a digital caliper. Evidence of infection was performed by blood smear collected from the animal’s tail 18 days after inoculation with observation of blood forms. Results: Comparing the intestinal diameter of the inoculated animals with 60,0000 trypomastigotes in the T0 of infection with T60 days after the inoculation, significant dilatation was observed between the proximal, medial and distal segments (p<0.01), indicating the establishment of the megacolon model. In addition, comparing intestinal diameter between the different segments, with in the T0 of infection and the T60 after inoculation, significant alterations were observed (p<0.05). Conclusion: The proposed model was possible for in vivo studies of alterations due to infection by T. cruzi and functional alterations of the colon. In addition, the changes manifested in the colon are not directly proportional to the size of the inoculum, but to the time of infection that the animals were submitted, since the animals inoculated with 60,0000 blood forms were the ones which presented the most significant alterations.

Background: The extract of Corchorus olitorius has a reasonable content of vitamins A and C, calcium, iron and fibre, and therefore enjoys a universal application in the treatment of some disease conditions, even as the whole leaf is a very important component of food in so many cultures. Purpose: The study was designed to investigate the effect of Corchorus olitorius extracts on the testis of adult Wistar rats. Method: A total number of thirty two adult Wistar rats weighing between 180 and 200 grammes separated into four groups labeled A,B,C and D respectively were used for the study. Animals in group A which served as the control group were fed with the normal rat chow and water only. The group B rats were administered 100mg/kg body weight of aqueous extract of Corchorus olitorus; while those in group C were administered 500mg/kg body weight of the extract. The group D rats received 1000mg/kg body weight of the extract. For a period of four weeks, the different experimental animal groups received the respective aforementioned treatments once daily, around nine- o’clock in the morning through oral intubation. At the end of the 28 day treatment, the animals were sacrificed and the testes harvested for histological, investigation, and through cardiac puncture, blood samples for some hormonal studies was also collected and investigated using standard laboratory standards. Results: Observations made showed that the extract produced no histological distortions, degenerative or defective effects on the testicular tissues. The testosterone levels of group B, C, and D rats were observed to be significantly higher (P<0.005) than that of the group A (control group).ound: The extract of Corchorus olitorius has a reasonable content of vitamins A and C, calcium, iron and fibre, and therefore enjoys a universal application in the treatment of some disease conditions, even as the whole leaf is a very important component of food in so many cultures.

The influence of age on serum biochemical components in the domestic rabbit was investigated. The serum total protein (g/dL), albumin (g/dL), globulin (g/dL), creatinine (mg/dL), urea mg/dL, cholesterol (mg/dL), Alkaline phosphatase (ALP; iu/l), Aspartate aminotranferase (AST; iu/l) and Alanine amimotransferase (ALT; iu/l) were assessed in 24 male rabbits at 7, 14 and 21 weeks of age to represent weaners, growers and pubertal stages. Data were analysed using descriptive statistics and analysis of variance at á . Results of 0.05 serum biochemistry revealed a steady significant increase in total protein (4.2±0.3; 5.3±0.5; 6.9±0.2), albumin (2.2±0.7; 2.8±0.4; 4.0±0.2), globulin (1.9±0.3; 2.5±0.4, 2.9±0.2), cholesterol (49.5±1.1; 56.4±4.2; 62.4±5.4) and creatinine (0.8±0.1; 1.2±0.1; 1.9±0.3) at 7, 14 and 21 weeks respectively. Serum urea levels were similar across the ages. The values recorded for ALP and AST at 7 weeks (39.6±7.5; 101.1±6.7) and 14 weeks (38.7±6.4; 104.5±8.7) were significantly higher than the 21 weeks (33.5±2.7; 95.8±5.9) while ALT at 7 weeks (27.33±5.6) was significantly lower than 14 (38.2±3.9) and 21 weeks (37.4±3.0). The age of the rabbits had a significant effect on their serum biochemical parameters. They should therefore be grouped according to age when setting serum reference values for them.

Background: Canine transmissible venereal tumour (CTVT) also known as infectious sarcoma, venereal granuloma, transmissible lymphosarcoma or sticker tumour is usually transmitted through coitus and mainly affects the external genitalia of young sexually matured dogs. Surgery, chemotherapy, radiotherapy and immunotherapy are considered as effective treatment protocols. Therefore, depending upon the availability present study was designed to investigate the efficacy of different surgico-chemotherapeutic protocols for treatment of canine transmissible venereal tumour.Methods: The study was conducted during January 2018 to July 2018 at the Teaching Veterinary Clinical Complex (TVCC) and Department of Veterinary Surgery and Radiology, College of Veterinary Science and A.H., Anjora, Durg (C.G.) on 18 canines of various breed, irrespective of age, sex and divided into three groups consisting 6 animals in each group. Group A was treated with surgical excision of tumour only where as Group B and Group C were treated with surgical excision of tumour followed by administration of Doxorubicin (30mg/m2) BSA and Vincristine sulphate (0.025 mg/kg) intravenously alongwith DNS at 7th and 14th post-operative days respectively. Different physiological and haemato-biochemical parameters (Hb, PCV, TLC, TPC, DLC, serum glucose, TSP, SUN, SC, ALT, AST and ALP) were recorded preoperatively, postoperatively and after chemotherapy at 10th, 30th and 60th days intervals.Result: The present investigation showed transient changes in physiological and haemato-biochemical parameters before, post surgery and post chemotherapeutic management and was within normal range. Histopathological examination revealed confluent sheet of tumour cells arranged in large round oval or polyhedral shaped distributed in tight clusters or cords. Group A showed mild to moderated reoccurrence while Group B showed minimum reoccurrence. Group C showed no reoccurrence. Thus, surgery combined with vincristine therapy is most effective for treating dogs suffering with transmissible venereal tumour.

Abstract Introduction: Arteether™, a derivative of artemisinin, is among the recent drugs that have given renewed hope for combating malarial menace. The present study investigated the effects of arteether™ on the histology of the retina and cerebellum of Wistar rats. Materials and Methods: Twenty adult albino Wistar rats weighing 150-200 g, were randomly divided into four groups (A, B, C and D) of five animals each and used for this study. Group A rats were given intramuscular (i.m.) arteether™ (3 mg/kg b.w.) daily for 3 days. Group B rats were given i.m. arteether™ (6 mg/kg b.w.) daily for 3 days. Group C rats were also given i. m. of arteether™ (3 mg/kg b. w.) daily for 3 days, and the same dose was repeated at two-weekly intervals for 4 further weeks; while Group D rats which received normal saline (0.9 % w/v, 3 ml/kg b.w.), served as controls. At the end of the experiment, the rats were sacrificed by cervical dislocation. The retina and cerebellum were excised and processed routinely for histopathology changes, using haematoxylin and eosin stain (H & E), as well as Nissl stain. Results: Results obtained showed normal cellular components of the retina and cerebellum in all groups, and no cyto-pathological changes were observed. Conclusion: Thus, this study showed that under light microscopic examination, therapeutic doses of arteether™ caused no significant cyto-pathologic changes in the retina and cerebellum of Wistar rats.
