Item Evidence of attenuation of intestinal ischemia–reperfusion injury following pre-treatment with methanolic extracts from Chromolena odorata in rats(Natural Health Product Research Society of Canada, 2015) Akinrinmade, J. F.; Akinrinde, S. A.; Odejobi, A.; Oyagbemi, A. A.Background: Chromolena odorata is a tropical species of flowering shrub in the family Asteraceae, leaves of it have been reported to be widely used as herbal remedy for the treatment of various ailments. It is particularly reported to be useful in the healing of wounds. Methods: We investigated the possibility of amelioration of intestinal ischemia–reperfusion (IR) injury in rats trea ted with methanolic extract of C. odorata (MECO). Wistar albino rats were divided randomly into five groups of six animals each as control, IR-treated, IR þ 200 mg/kg MECO, IR þ 400 mg/kg MECO, and IR þ 200 mg/kg vita min C. Pre-treatment with MECO or vitamin C was for 7 days. Results: The contents of hydrogen peroxide (H2O2) and malondialdehyde (MDA) were significantly reduced by MECO and vitamin C, while there were significant enhancements of the activities of superoxide dismutase (SOD), glutathione peroxidase (GPX), catalase (CAT), as well as the content of reduced glutathione (GSH) in pre-treated rats compared to IR-treated rats. Glutathione S-transferase (GST) activity was not significantly affected in all the groups. Histopathological examination of small intestinal mucosa revealed significant attenuation of intestinal pathology in animals pre-treated with MECO, while IR injury produced severe villi erosion, necrosis, and inflammatory cell infiltrations. Conclusions: The present study highlights the antioxi dant activities of MECO and its ability to inhibit inflammatory cell infiltration as mechanisms involved in its protection against IR injury in the intestine of rats, an effect that was largely comparable to that of vitamin C.Item Evidence of attenuation of intestinal ischemia–reperfusion injury following pre-treatment with methanolic extracts from Chromolena odorata in rats(Natural Health Product Research Society of Canada, 2015) Akinrinmade, J.

F.; Akinrinde, A. S.Item Effect of oral administration of methanolic extract of Ocimum gratissimum on intestinal ischemia-reperfusion injury in Rats(Sciencedomain International, 2013) Akinrinmade, J. F.; Akinrinde, A. S.Aim: The effect of the methanolic extract of Ocimum gratisimum (OG) leaves on thetissue damage induced by ischemia-reperfusion (IR) injury in the rat intestine wasinvestigated. Study Design: Randomized controlled experiment.Place and Duration of Study: Experimental Animal Unit and Faculty of VeterinaryMedicine, University of Ibadan, Nigeria from March to May, 2013. Methodology: 18 rats were divided randomly into 3 groups of 6 rats each. Group I served as control; Group II had IR injury by laparotomy with clamping of the Superior mesenteric artery (SMA) for 30 minutes followed by removal of the clamp for 45 minutes; Group III was pre-treated orally for 7days with methanolic extract of Ocimum gratissimum (MEOG)followed by IR injury. Sections of the duodenum and ileum were cut for histopathological examination. The remaining tissues were processed for the determination of biochemical markers of oxidative stress including Hydrogen peroxide (H2O2), Malondialdehyde (MDA) and Glutathione concentrations. Results: Mean values of MDA and H2O2 levels were significantly elevated (P=0.004 and P=0.03, respectively) in intestinal tissues following IR compared to control while reduced glutathione (GSH) levels were not significantly altered. OG (500mg/kg) caused significant reduction (P=0.02 and P=0.04) in MDA concentrations and H2O2 generation, respectively compared with the IR group. Histopathological examination revealed erosions and stunting of the villi tips in the duodenum and ileum, with severe mononuclear infiltration at the mucosal surface in the IR group. No visible lesions were observed in the intestine of the control group, with no significant alterations in the intestinal epithelium of the OG-treated rats. Conclusion: The results suggest that OG may provide some protection against intestinal mucosal injury induced by ischemia-reperfusion, through its anti-oxidative effects.Item Earfly bite wounds in dogs in Ibadan, South-West Nigeria(Academic Journals, 2013) Akinrinmade, J. F.; Akinrinde, A. S.A study was conducted in Ibadan, South-West Nigeria between 2005 and 2009 to determine the prevalence, risk factors and management protocols employed in earfly bite wounds in dogs. Review of case records, physical examinations and administration of structured questionnaire were used to obtain information with regard to the number of cases of earfly bite wounds presented, signalment, anatomical features, treatment modalities and response. Prevalence of earfly bite wounds was 11.73%. Sex, breed, anatomical features and management exhibited significant influence on the incidence of earfly bite wounds. Effectiveness of management protocols was low with significantly high recurrence rate. The results showed a significantly high association between earfly bite wounds and aural hematoma and otitis externa.Item Rumen impaction with foreign indigestible materials in domestic ruminants in Nigeria: A Review(Faculty of Veterinary Medicine, University of Ibadan, 2012) Akinrinmade, J. F.Rumen impaction due to foreign, indigestible materials has become one of the major gastro-intestinal disorders in ruminant livestock causing severe loss of meat and milk production and high mortality rates. Ingested foreign bodies affect the health of animals and cause economic loss to the owner. Among other factors, the current widespread use of polythene and other non-biodegradable materials with improper waste disposal is a major predisposing factor to the development of rumen impaction. In this paper, the Nigerian situation with regard to the prevalence, reported fatalities, composition of recovered foreign materials, risk factors and clinical signs of foreign body rumen impaction are reviewed, including the clinical management approaches to the condition, the hemato-biochemical, trace element profile and pathology of the rumen in affected animals. The review also provides information on the waste disposal situation in Nigeria as it relates to the development of this condition with emphasis on its economic implications and the preventive strategies to counteract the problem of rumen impaction.Item Hematological and serum biochemical indices of West African dwarf goats with foreign body rumen impaction(Physiological Society of Nigeria, 2012) Akinrinmade, J. F.; Akinrinde, A. S.Hematological and biochemical parameters were determined in 82 West African Dwarf goats with foreign body rumen impaction (FBR) and 40 normal WAD goats without foreign body rumen impaction (WFBR) in order to evaluate their influence on the etio-pathogenesis of rumen impaction. The mean PCV (26.22%), RBC (9.03 X 106/µL), Hb (8.38g/dl) and MCHC (32.20g/dl) were significantly lower (P<0.05) in FBR than in WFBR. The values obtained for serum sodium, potassium, calcium and magnesium in FBR goats were not significantly different (P<0.05) from that of WFBR goats. Mean values of serum total protein (4.02gm/dl), phosphorus (3.38mg/dl), glucose (29.33gm/dl), zinc (0.72mmol/L) and copper (0.49mmol/L) in FBR goats were significantly lower than in WFBR goats. The results suggest that foreign body rumen impaction in WAD goats is influenced by some hematological (PCV, RBC, Hb, MCHC) and serum biochemical (total protein, phosphorus, glucose, zinc, copper) parameters and can be used as a basis for formulating preventive measures.Item Aflatoxin status of some commercial dry dog foods in Ibadan, Nigeria(Academic Journals, 2012) Akinrinmade, J. F.; Akinrinde, A. S.The occurrence of aflatoxins B1, B2, G1 and G2 in commercial dry dog foods in the city of Ibadan, Southwest Nigeria, was investigated. Dry dog food samples from 6 producers were purchased on five different occasions from retail outlets in Ibadan, Nigeria. High performance liquid chromatography was used for separation and quantification of aflatoxin fractions, after consideration of the limits of detection and quantification of the method. Results indicate that aflatoxins B1, B2, G1 and G2 were detected in all the samples investigated, with B1 being the most abundant. The range of concentration of total aflatoxins was 7.76 to 11.93 µg/kg (mean: 9.61 µg/kg). The results show that dry dog foods marketed in Ibadan are frequently contaminated with aflatoxins, exposing dogs to adverse effects of aflatoxicosis. Scientifically based regulations for the acceptable limit of mycotoxins in pet foods in the country would be beneficial.Item Aflatoxin status of some commercial dry dog foods in Ibadan, Nigeria(Academic Journals, 2012) Akinrinmade, J.
