What Researchers Did
Taiwanese researchers used mice with surgically created limb ischemia (blocked blood supply) to test whether HBOT at 3 ATA for one hour per day for five days could restore blood flow and stimulate new vessel growth.
What They Found
Mice receiving HBOT showed significantly better blood flow recovery and more new blood vessel growth (confirmed by laser imaging and CD31 staining) compared to untreated mice. HBOT also reduced damaging reactive oxygen species (ROS) and increased levels of pro-growth proteins: VEGF, HO-1, HIF-1, and Nrf2.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
This was a healthy mouse model of surgically induced ischemia, which may not reflect the chronic, progressive blood vessel disease typical of human patients with peripheral artery disease.
