Gastrodin Attenuates Neuronal Apoptosis and Neurological Deficits after Experimental Intracerebral Hemorrhage.

Objective: Gastrodin, a glucoside of gastrodigenin, inhibits cerebral oxidant stress and apoptosis in multiple central nervous system injury, but its effect in intracerebral hemorrhage (ICH) remains unclear. This study investigated the effect of gastrodin on neuronal apoptosis and neurological deficits in rat ICH model.

Methods: In vitro experiments were performed using hematoma lysate-induced cell damage model in primary cortical neurons.

Carnosine Attenuates Brain Oxidative Stress and Apoptosis After Intracerebral Hemorrhage in Rats.

Carnosine, an endogenous dipeptide (β-alanyl-L-histidine), exerts multiple neuroprotective properties, but its role in intracerebral hemorrhage (ICH) remains unclear. This study investigates the effect of Carnosine on brain injury using the rat ICH model, which is established by type IV collagenase caudatum infusion. The results indicate that intraperitoneal administration of Carnosine (1000 mg/kg) significantly attenuates brain edema, blood-brain barrier (BBB) disruption, oxidative stress, microglia activation and neuronal apoptosis of perihematoma at 72 h following ICH in rats models, as convinced by preventing the disruption of tight junction protein ZO-1, occludin and claudin-5, followed by the decrease of ROS, MDA, 3-NT, 8-OHDG level and the increase of GSH-Px and SOD activity, then followed by the decline of Iba-1, ED-1, active caspase-3 and TUNEL positive cells and the decrease of IL-1β, IL-6, TNF-α, active caspase-3 and cytochrome c level.

Enhanced Neuroprotection of Minimally Invasive Surgery Joint Local Cooling Lavage against ICH-induced Inflammation Injury and Apoptosis in Rats.

Hypothermia treatment is one of the neuroprotective strategies that improve neurological outcomes effectively after brain damage. Minimally invasive surgery (MIS) has been an important treatment of intracerebral hemorrhage (ICH). Herein, we evaluated the neuroprotective effect and mechanism of MIS joint local cooling lavage (LCL) treatment on ICH via detecting the inflammatory responses, oxidative injury, and neuronal apoptosis around the hematoma cavity in rats.
