Item Small bowel responses to enteral honey and glutamine administration following massive small bowel resection in rabbit(2008) Evarefe, O.D.; Emikpe, B.O.; Arowolo, R. O. A.The trophic effects of honey and glutamine in the healing and adaptation of the small bowel following intestinal resection were studied in some Nigerian non-descript breeds of rabbits. Nine rabbits of mixed sexes with mean body weight of 1.45 ±0.55kg were used. They were randomised into three treatment groups following 50% small bowel resection. Group A rabbits were placed on oral honey treatment. Group B on oral glutamine and group C on normal saline (control). All groups exhibited signs of small bowel adaptation (glutamine(B) honey (A) control (C) at the end of the experiment (4 weeks) with oral glutamine showing the best overall effects on intestinal mucosal growth and adaptation evidenced by significant increase (P<0.05) in residual bow'el length (37.3%), villi width (20.0%), crypt depth (113.3%) and a non significant increase in villus height (33.3%) and cellular mass (10.2%). Honey showed a better effect than control with a significant increase (P<0.05) in villi width (18.2%), crypts depth (66.7%) and cellular mass (33.9%) and a non significant increase in gross residual bow'el length (24.6%), and villus height (30.5%). Our result shows that honey and glutamine have trophic effects on bowel mucosa healing and hyperplasia and have potential therapeutic effects on massive bowel resection in humansItem Effects of honey, glutamine and their combination on canine small bowel epithelial cell proliferation following massive resection(Physiological Society of Nigeria, 2012-12) Eyarefe, O.D,; Emikpe, B.O.; Akinloye, S.O.; Alonge, T.O.; Fayemi, O.E.The effects of honey, glutamine and honey/glutamine combination on the healing and adaptive process of the bowel following massive small bowel resection were studied in some Nigerian non-descript breeds of dogs. 24 dogs (3-4months old) of mixed sexes with mean body weight of 4.42±0.70 kg were studied. They were randomized into four treatment groups following 70% small bowel resection. Group A dogs were placed on glutamine treatment, Group B on oral glutamine/honey and group C on honey and group D normal saline (control). Their body weights were evaluated for 15 days and the pre- and post-treatment gut biopsy samples were obtained and processed for morphometric evaluation. All groups exhibited signs of small bowel adaptation (Glutamine/honey>glutamine > honey > control) at the end of the experiment (4 weeks). Glutamine/honey combination, glutamine and honey had gradual increase in body weight from days 3-15 of weight evaluation. The control group, however, had a remarkable drop in body weight compared with other groups. Oral glutamine/honey combination showed the best overall effect based on body weight gain, intestinal mucosal growth and adaptation, evidenced by increased in residual bowel Villi height (27.71μm), Villi weight (14.51μm), Crypt depth (11.25μm), and Villi density (3.40μm). Glutamine showed a better result than honey with a significant increase in villi height (38.08μm), width (8.48μm) and crypt depth (40μm). Histologically, an improved villi branching was observed with glutamine/honey combination. Our results showed that honey/glutamine combination had comparative therapeutic advantage over glutamine or honey and may be a preferred treatment for short bowel syndrome patientsItem Wound healing potential of natural honey in diabetic and non-diabetic wistar rats(2014-01) Eyarefe, O.D.; Ologunagba, F. M.; Emikpe, B.O.The cutaneous wound healing effects of natural honey were compared in diabetic and non-diabetic rats. Thirty adult male Wistar rats (159g ± 31.5) where randomized into alloxan diabetics (n=15) and non-diabetic (n=15) groups. A 6mm full thickness biopsy punch wound was created on the nape of each rat under 2% xylazine (5mg/kg) and 5% ketamine (35mg/kg) anaesthesia. The wounds were contaminated with Staphylococcus aureus (108 Colony Forming Unit (CFU). Each group was then randomised into three subgroups: A [control, n=5], B (n=5) amikacin (0.8mg) and C (n=5) natural honey (0.1 ml) topical treatments. Wounds were evaluated at day: 3, 5, 7, 9, 11, 13, and 15 for wetness, oedema, hyperemia, granulation tissues, and contraction. Wounds of animals in the diabetic group showed significantly less (p>0.05) wetness compared with the non-diabetic group at days 3-5 (p=0.002) and 5-9, p=0.002 while the amikacin subgroup of the non-diabetic group showed non-significant but notable level of wetness at days 5-7. A significantly (p>0.05) more wound edge oedema was shown by the diabetic than the non-diabetic group at days 3-5 (p=0.000) with the trend being; control > amikacin > honey. The percentage of animals with wound edge oedema between days 3-5 in the non-diabetic group was honey (20%), amikacin (20%) and control (60%); and diabetic group was honey (40%), amikacin (100%) and Control (100%). Between days 5-7, 80% of wounds in both groups where without wound edge oedema except the control subgroups. Wounds of rats in the diabetic group were significantly more hyperaemic (p>0.05) at days 5-9 (p=0.001) and days 9-15 (p=0.000), with the trend being control > amikacin = honey. Wounds of rats in the non-diabetic groups healed with significantly more (p < 0.05) granulation tissues at days 5-9 (p=0.001) (honey = amikacin > control). Control group at days: 5-9 (p=0.001), 9-15 (p=0.000); amikacin at days: 5-9 (p=0.002), 9-15 (p=0.005); and honey at days: 5-9 (p=0.005) and 9-15 (p= 0.001). Differences in wound diameter (a reflection of wound contraction) were not significantly notable in both subgroups (p > 0.05) at various days of measurement except at days 3-5(p=0.008). Honey and amikacin were effective in enhancing cutaneous wounds healing in wistar rats studied. In diabetic rats, honey showed a promising result when compared to amikacin hence honey could be recommended for wound management of diabetic patient in human and animal hospitalsItem Honey, an unexplored topical wound dressing agent in Nigerian veterinary practice(2016-12) Eyarefe, O.D.; Oguntoye, C.O.This paper presents an overview of honey as a wound dressing agent, its mechanism of action, selected cases of wounds managed with honey and a survey of veterinarians’ perception and usage of honey for wound management in Nigeria. Structured questionnaires were administered to veterinary practitioners predominantly in Southwest Nigeria to evaluate their awareness, usage and concerns about honey as a wound dressing agent. Case reports of animal patients’ wounds managed with honey are presented in a logical fashion to showcase honey efficacy in wound management. There was remarkable healing with honey in the cases managed. Many of the respondents did not consider honey as first choice in wound management and availability of pure honey is a major concern expressed with honey use. More veterinarians in Nigeria should use honey for its high efficacy and cost effectiveness in the management of animal woundsItem Enhanced electroscalpel incisional wound healing potential of honey in Wistar rats(Elsevier, 2017) Eyarefe, D. O.; Kuforiji, D. I.; Jarikre, T. A.; Emikpe, B. O.Electrosurgery reduces surgical bleeding, and delays wound healing. This study evaluates incisional wound healing potential of honey in wounds created with electroscalpel and cold scalpel. The study used twelve (12) adult male albino rats (130 ± 20 g), randomly grouped into Electro-cautery (n = 6) and Cold scalpel (n = 6). Each rat had three full thickness (6 mm diameter) skin wounds (a, b and c) created on its dorsum with either Electroscalpel (ES) or Cold blade scalpel (CS), and treated topically with Silver sulphadiazine (SSD, wound a), untreated (control, wound b) and Bee honey (H, wound c). The wounds were evaluated for gross (exudation, edema, hyperemia, contraction), histologic (granulation, angiogenesis, fibroplasia, epithelialization) and immunologic healing indices using standard techniques. Data were analyzed with Chi-square, Two-way Analysis of Variance (ANOVA) and Duncan Multiple Range tests (DMRT) at a = 0.05. Wound hyperemia and edge edema were prominent in the ES group from day 4 to 6 (P = .000). Percentage wound contraction was higher in the CS than ES group from days 5 to 7 (P = .006) and in the CS treated with honey than ES treated with honey from days 7 to 14 (P = .000). Granulation tissue reduced in ES group treated with SSD than in honey and control wounds. Fibroelastic tissue increased in SSD and honey treated wounds of ES group, and higher in honey treated wounds of CS group (P < .05). Fibroplasia was sustained in honey and SSD treated wounds than control. Honey can be applied to electroscalpel surgical wound to facilitate rapid healing during surgical management of tumours having vascular network
