[THE EFFECT OF PERINATAL HYPOXIA ON THE STRUCTURE OF BLOOD-BRAIN BARRIER IN RATS TREATED WITH SALIFEN]

Area of Science:

• Neuroscience
• Pharmacology
• Developmental Biology

Background:

• Perinatal hypoxia can negatively impact brain development and the blood-brain barrier (BBB).
• Understanding the BBB's response to early-life hypoxia is crucial for developing neuroprotective strategies.
• The drug salifen's effects on the BBB following hypoxia have not been extensively studied.

Purpose of the Study:

• To investigate the impact of salifen on the structural integrity of the blood-brain barrier (BBB) in Wistar rats.
• To evaluate salifen's efficacy in mitigating the adverse effects of early-postnatal hypoxia on the neocortex.
• To assess the compensatory-adaptive responses of the BBB elements to hypoxia with salifen treatment.

Main Methods:

• Wistar rats were divided into three groups: hypoxia with salifen treatment, hypoxia only, and intact controls.
• Light and electron microscopy were employed to examine BBB structural characteristics in the neocortex.
• Hypoxia was induced on postnatal Day 2, modeling human preterm pregnancy complications.

Main Results:

• Salifen treatment demonstrated a positive effect on the microvasculature following perinatal hypoxia.
• The drug notably improved the condition of endothelial cells within the BBB.
• Evidence suggests salifen actively participates in compensatory-adaptive reactions of the BBB to hypoxic stress.

Conclusions:

• Salifen exhibits protective properties against structural damage to the blood-brain barrier caused by early-postnatal hypoxia.
• The findings support the potential therapeutic application of salifen in conditions involving perinatal hypoxia.
• Further research into salifen's neuroprotective mechanisms and long-term effects is warranted.
