Potential effect of physical exercise on the downregulation of BDNF mRNA expression in rat hippocampus following intracerebral hemorrhage.

Objectives: Physical exercise is known to induce expression of the neuroprotective brain derived neurotrophic factor (BDNF) in the hippocampus. This study examined the effects of physical exercise on hippocampal BDNF expression and the potential benefits for preventing remote secondary hippocampal damage and neurological impairment following intracerebral hemorrhage (ICH).

Materials And Methods: Wistar rats were randomly assigned to sham-operated, ICH, and ICH followed by exercise (ICH/Ex) groups.

Epigenetic modification of histone acetylation in the sensorimotor cortex after intracerebral hemorrhage.

Epigenetic regulation is involved in post-stroke neuroplasticity. We investigated the effects of intracerebral hemorrhage (ICH) on histone acetylation and gene expression related to neuronal plasticity in the bilateral sensorimotor cortices, which may affect post-stroke sensorimotor function. Wistar rats were randomly divided into the SHAM and ICH groups.

Combined treatment with exercise and α5GABAR inhibitor promotes motor function recovery after intracerebral hemorrhage.

The present study aimed to examine the synergistic effects of exercise and pharmacological inhibition of the α5 subunit-containing gamma-aminobutyric acid (GABA) receptors (α5GABAR) on motor function recovery after intracerebral hemorrhage (ICH). Wistar rats were divided into five groups (n = 8 per group): SHAM, ICH, ICH + exercise (ICH + EX), ICH + L-655,708 (ICH + L6), and ICH + L-655,708 and exercise (ICH + L6EX) groups. ICH was induced by microinjection of a collagenase solution.
