    Nigerian veterinarians’ attitude and response to small animal pain management
    (Academic Journals, 2017-12) Oguntoye, C.O.; Eyarefe, O.D.
    Nigerian veterinarians’ attitude and responses to pain management predominantly in small animals were evaluated using a structured questionnaire. The questionnaires were administered to representatives of seventy small/large animal clinics and hospitals distributed across ten states of the country. The respondents possess the Doctor of Veterinary Medicine (DVM) (58.6%), Master of Veterinary Science MVSc (32.9%) degrees, fellowship diplomas (5.7%) and PhD (2.9%) degree. Majority of the respondents (92.9%) had less than 20 years of post DVM clinical experience. Seventy- nine percent (79%) had good understanding of animal pain perception while 43% still hold the misconception that some degree of pain is beneficial to an animal after surgery. Pain rating excellently assigned to fracture reduction by 83% of practitioners, but inappropriately assigned by 66% of practitioners to caesarean section, 66% to laparotomy, 63% to ovariohysterectomy, 60% to mastectomy and 60% to dental procedures. Xylazine, lignocaine and ketamine were anaesthetic/analgesics commonly used. Respondents (98%) recognized pain based on animal’s response to painful body part palpation, attitude of animal (97%), history by care giver (80%) and inappetence (73%). Determinants of analgesic drug choice for dogs/cats were: analgesic efficacy (99/29%); potential for toxicity (95/38%); availability (93/43%), side effect (86/42%), cost (82/37%), availability of information on the drug (76/36%), and ability of analgesic drug to cause sedation in the animal (65/33%). Respondents sourced information for analgesic therapeutics from: literature (73%), internet (80%), and drug leaflet (98%). In conclusion, most veterinarians surveyed had understanding of animal pain perception and use anaesthetic protocols that provide analgesia. Nonetheless, some of them still hold on to the misconception that minimal pain perception is beneficial to the patient at the post-operative period which may have influenced their non-provision of additional analgesia post-operatively

    Pathological and immunohistochemical evaluation of wound healing potential of Nigerian bee propolis in albino rats
    (Springer-Verlag London, 2018) Eyarefe, O. D.; Ozota, C. A.; Jarikre, T. A.; Emikpe, B. O.
    This study evaluated the efficacy of the Nigerian bee propolis as a wound healing agent, on full thickness skin wounds of healthy adult male (150.0 ± 0.5 g) albino rats randomly divided into three treated groups (propolis extract (PE), propylene glycol (PG), silver sulfadiazine) and an untreated group. Each rat had three circular full thickness skin wounds created on the cranial, middle, and caudal surface of the rat’s dorsum. The wounds in each group were topically treated with bee propolis extract (PE, 0.1 ml), propylene glycol (PG, 0.1 ml) and silver sulfadiazine (SS, 0.1 ml) twice daily for 21 days, except the untreated group (UT). The wounds were evaluated for gross (exudation, edema, hyperemia, wound contraction), histologic (granulation, angiogenesis, fibroplasia, epithelialization), and expression of epidermal growth factor (EGF) using standard techniques. Data was descriptively summarized as percentages, mean and analyzed using Chi-square and analysis of variance at α = 0.05.Wound edge edema (WEE), hyperemia, and exudation were prominent in all the groups between days 0–2.WEE was significantly less on day 3 in the PE (14%) and SS (14%) groups, compared with the PG (35%) and UT (66%) groups. Wounds treated with PG and UT were significantly more hyperemic than those with PE and SS. Wound contraction was significantly less on day 2 in the UT wounds when compared to the treated wounds (PE = 12.63%, SS = 2.22%, PG = 4.94%, and UT = − 2.82%). The wound contraction was remarkable between days 4–8 in the PE- and SS-treated wounds (PE > SS > PG > UT). The microscopic changes at days 4, 8, 12, 16, and 21 showed significant evidence of epithelial proliferation, improved angiogenesis, granulation, and fibrous connective tissue in the PE- and SS-treated rats compared with the negative controls. The inflammatory response showed that the PE group had the highest amount of macrophages and leucocytes on day 4 with the trend being PE > SS > PG > UT. Neutrophils regressed in the treated wounds on day 8 but were consistently high in the untreated group from days 4–16. The immunohistochemical evaluation showed that the intensity of EGF was consistently high in the SS- and PE-treated wounds. Nigerian bee propolis extract accelerated wound healing similar to that of silver sulfadiazine based on wound healing indices and is therefore recommended for the management of wounds especially in low-income communities where propolis is available and affordable
