Wistar Albino Sıçanlarında Agresif Davranış ve Aflatoksine Maruz Kalma
A A Ishola
 University of Ibadan, Ibadan, Nigeria
Arka plan: Aflatoksin B1 (AFB1) gıda kontaminasyonları, özellikle Sahra altı Afrika'da insan ve hayvan sağlığı üzerinde etkiye sahiptir. Bununla birlikte, Aflatoksinlerin saldırganlık davranışındaki rolü üzerine hayvan modeli çalışmaları sınırlıdır ve bu, çocuklarda ve yeni ortaya çıkan yetişkinlerde zihinsel sağlık ve saldırganlık için etkiye sahiptir. Amaçlar / Amaç: Wistar sıçanlarında aşırı bölgesel saldırganlık davranışında AFB1'in rolü değerlendirildi. Gereç / Yöntemler: Deney grubundaki (Grup A, n = 6) kemirgenler 1-12. Günlerde 0.3 mg / kg / gün uygulanan dimetilsülfoksit içinde seyreltilmiş AFB1 ile oral yoldan infüze edildi. Kontroller, 1-12. Günlerde benzer şekilde damıtılmış su aldı (Grup B). Gözlem için, aflatoksin ile muamele edilmiş deneysel sıçanlar ve damıtılmış su ile muamele edilmiş fareler olan deneysel sıçanlar olan sakinleri içeren kafese bir davetsiz misafir sokuldu. Davetsiz misafirlere karşı deney ve kontrol fareleri tarafından sergilenen bölgesel agresif davranışların gözlemlerinin kayıtları kaydedildi. Her fareye her biri 5 dakikalık üç deneme verildi. Çalışma, rastgele bloke edilmiş iki yönlü ANOVA'yı (faktör zaman çizelgesi × tedavi), ardından verileri analiz etmek için Bonferroni düzeltmesini kullanan bir post hoc analizi kullandı ve istatistiksel anlamlılık P <0.05 olarak ayarlandı. Bulgular: Bulgular, aflatoksine maruz kalmanın Wistar sıçanları arasında agresif davranışı önemli ölçüde etkilediğini göstermiştir F (1, 322) = 29.89, P <0.001, η2 = 0.09. Aflatoksin ile tedavi edilen hayvanlar, damıtılmış su ile tedavi edilen hayvanlardan önemli ölçüde daha agresif davranış sergiledi (Bonferroni = 4.04, P <0.001). Aflatoksine maruz kalma süresi, Wistar sıçanları arasında agresif davranışı önemli ölçüde etkilemek için tedavi ile etkileşime girdi F (1, 322) = 3.26, P <0.001, η2 = 0.10. Ortalama karşılaştırma, aflatoksin ile tedavi edilen ve damıtılmış su ile tedavi edilen sıçanların 1-7. Günler arasında agresif davranışında önemli bir fark olmadığını ortaya koymaktadır. Ancak 8. günden 12. güne kadar önemli farklılıklar gözlendi. Kronik maruziyet 7 günden fazla arttıkça saldırgan davranış% 10 arttı. Sonuç: Kemirgenlerde aflatoksin kaynaklı toksisite, nörobilişsel düşüşün şiddetlenmesi ve agresif davranışa yol açan beyin biyokimyasal bozulmaları yoluyla saldırganlığı etkiledi.
Exposure To Aflatoxin And Aggressive Behavior Among Wistar Albino Rats
Background: Aflatoxin B1 (AFB1) contaminations of food have impact on human and animal health especially in sub-saharan Africa. However Animal model studies on the role of Aflatoxins in aggression behaviour is limited and this have implication for mental health and aggressive in children and emergent adults. Aims/Objective: The role of AFB1 in excessive territorial aggression behavior in Wistar rats was assessed. Material/Methods: Rodents in the experimental group (Group A, n = 6) were orally infused with AFB1 diluted in dimethylsulfoxide administered 0.3 mg/kg/day on days 1–12. Controls received distilled water similarly on days 1-12 days (Group B). For the observation, an intruder was introduced into the cage containing the residents who are experimental rats treated with aflatoxin and rats in the control treated with distilled water. Records of observations of territorial aggressive behaviors exhibited by the experimental and control rats toward the intruder were recorded. Each rat was given three trials of 5 min each. The study utilized the randomized blocked two-way ANOVA (factors timeline × treatment), followed by a post hoc analysis using Bonferroni correction to analyze the data, and statistical significance was set at P < 0.05. Results: Findings demonstrated that exposure to aflatoxin significantly influenced aggressive behavior among Wistar rats F (1, 322) = 29.89, P < 0.001, ?2 = 0.09. Aflatoxin-treated animals significantly exhibited more aggressive behavior than animals treated with distilled water (Bonferroni = 4.04, P < 0.001). Exposure time to aflatoxin interacted with treatment to significantly influence aggressive behavior among Wistar rats F (1, 322) = 3.26, P < 0.001, ?2 = 0.10. The mean comparison reveals that there was no significant difference in aggressive behavior of the aflatoxin-treated and distilled water-treated rats from days 1–7. However, significant differences were observed from the 8th day onward to the 12th day. Aggressive behavior increased by 10% as the chronic exposure increases more than 7 days. Conclusion: Aflatoxin-induced toxicity in rodents influenced aggression through exacerbation of neurocognitive decline and brain biochemical distortions leading to aggressive behavior.
