Neuroprotective Effects of Dexpanthenol on Rabbit Spinal Cord Ischemia/Reperfusion Injury Model

Area of Science:

• Neuroscience
• Biochemistry
• Pharmacology

Background:

• Spinal cord ischemia/reperfusion injury (SCIRI) causes significant oxidative damage and inflammation.
• Dexpanthenol (DXP) is known for its protective effects against oxidative stress in various inflammation models.

Purpose of the Study:

• To evaluate the effects of DXP on oxidative stress, inflammation, apoptosis, and neurological recovery in a rabbit SCIRI model.
• To determine the potential of DXP as a therapeutic agent for SCIRI.

Main Methods:

• Rabbits were subjected to 20 minutes of spinal cord ischemia and randomized into control, ischemia, vehicle, methylprednisolone, and DXP treatment groups.
• Neurological function was assessed using the Tarlov scale.
• Biochemical markers of oxidative stress (malondialdehyde, catalase, xanthine oxidase) and apoptosis (caspase-3) were measured.
• Myeloperoxidase activity and histopathological/ultrastructural changes were analyzed.

Main Results:

• SCIRI significantly increased markers of oxidative stress and apoptosis while decreasing antioxidant activity.
• DXP treatment significantly reduced malondialdehyde, caspase-3, myeloperoxidase, and xanthine oxidase levels.
• DXP treatment increased catalase activity and improved histopathological, ultrastructural, and neurological outcomes compared to controls.

Conclusions:

• DXP demonstrated significant antioxidant, anti-inflammatory, antiapoptotic, and neuroprotective effects in a rabbit SCIRI model.
• These findings suggest DXP holds potential for treating SCIRI, warranting further investigation.
• This is the first study to explore DXP's comprehensive effects on SCIRI.
