Summary
Mildronate treatment improved cerebral blood flow restoration in rabbits after ischemia. Faster normalization of cerebral vessel reactivity was key to optimizing blood flow, more so than the absolute flow level.
Area of Science:
- Neuroscience
- Pharmacology
- Cardiovascular Science
Background:
- Cerebral ischemia and local lesions significantly impair cerebral blood flow (CBF) and vascular reactivity.
- Restoration of normal CBF and vascular function is critical for recovery after brain injury.
Purpose of the Study:
- To investigate the effect of mildronate on the restoration of cerebral blood flow and vascular reactivity following induced ischemia and local lesions in rabbits.
- To determine if mildronate enhances recovery processes by influencing cerebral vascular dynamics.
Main Methods:
- Rabbits were administered mildronate (25 mg/kg, i.v.) daily for 14 days.
- Cerebral blood flow and vascular reactivity were assessed after inducing local lesions and ischemia.
Main Results:
- Mildronate administration accelerated the normalization of cerebral vascular reactivity.
- This faster normalization of reactivity played a more significant role in optimizing cerebral blood flow recovery than the absolute CBF level.
- Overall restorative processes were improved by mildronate treatment.
Conclusions:
- Mildronate demonstrates a beneficial effect on recovery from cerebral ischemia and lesions.
- Enhancing cerebral vascular reactivity is a crucial mechanism by which mildronate aids in optimizing cerebral blood flow restoration.
