Assessment of the potential protective effects of culture filtrate of Trichoderma harzianum to ameliorate the damaged histoarchitecture of brain in epileptic rats.

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.
