The simultaneous hyperexcitability of the neural network is the most well-known manifestation of epilepsy that causes recurrent seizures. The current study was aimed to examine any potential safety benefits of the culture filtrate of Trichoderma harzianum (ThCF) to ameliorate damaged histoarchitecture of the brain in epileptic rats by assessing seizure intensity scale and behavioral impairments and follow up the spontaneous motor seizures during status epilepticus phases in rats. Twenty-four rats were divided into four groups; control (C), epileptic (EP) valproic acid-treated epileptic (EP-VPA), and epileptic treated with T. harzianum cultured filtrate (ThCF). In addition to a seizure intensity score and behavioral tests, routine H&E and Golgi-Copsch histopathology, were used to examine the cell somas, dendrites, axons, and neural spines. ThCF treatment increased activity and recorded movements during grooming, rearing, and ambulation frequency. Brain tissues of epileptic rats exhibited detached meninges, hypercellularity, mild edema in the cortex and markedly degenerated neurons, degenerated glial cells, and microcyst formation in the hippocampus. Moreover, brains of EP-ThCF were noticed with average blood vessels, and increased dendritogenesis. The current data revealed some of negative effects of epileptogenesis brought on by seizure intensity score and retarded histopathological alterations in the hippocampus. Therefore, the study is forecasting to identify novel active components from the metabolites of T. harzianum with a crucial therapeutic role in various disorders.
神经网络的同步过度兴奋是癫痫最著名的表现形式,导致反复发作。本研究旨在通过评估癫痫大鼠的癫痫发作强度量表和行为障碍,以及跟踪癫痫持续状态期间大鼠的自发性运动性癫痫发作,来检查哈茨木霉(ThCF)培养滤液对改善受损的大脑组织形态结构的任何潜在的安全性益处。24 只大鼠被分为 4 组;对照组(C)、丙戊酸致痫组(EP-VPA)、癫痫组和哈茨木霉培养滤液(ThCF)治疗组。除了癫痫发作强度评分和行为测试外,还使用常规 H&E 和高尔基-科普希组织病理学检查来检查细胞体、树突、轴突和神经棘。ThCF 治疗增加了梳理、站立和活动的频率。癫痫大鼠的脑组织表现出脑膜分离、皮质细胞增多、轻度水肿和明显的神经元退行性变、神经胶质细胞退行性变以及海马微囊形成。此外,EP-ThCF 的大脑中可以发现平均血管数量增加,树突生成增加。目前的数据显示了癫痫发作强度评分和海马组织病理学改变迟缓带来的一些癫痫发生的负面影响。因此,该研究预测从哈茨木霉的代谢产物中识别出具有各种疾病关键治疗作用的新型活性成分。
