Hypothesis
The study investigates the therapeutic effect of insulin and vitamin C on cerebral vasospasm after subarachnoid hemorrhage.
Conclusion
Combinatorial treatment with insulin and vitamin C has effectively relieved cerebral vasospasm after subarachnoid hemorrhage in rabbits.
Supporting Evidence
- The vascular cross-sectional area in the SAH + insulin + vitamin C group showed no significant difference from the control group.
- Insulin receptor α expression was significantly downregulated in the SAH, SAH + insulin, and SAH + vitamin C groups.
- NO levels in serum and cerebrospinal fluid decreased significantly in the SAH, SAH + insulin, and SAH + vitamin C groups.
Takeaway
Giving insulin and vitamin C together helps stop blood vessels in the brain from tightening after a brain bleed in rabbits.
Methodology
The study used a rabbit model of subarachnoid hemorrhage and treated groups with insulin, vitamin C, or both, measuring vascular cross-sectional area and nitric oxide levels.
Limitations
The results may not directly apply to humans due to anatomical differences between rabbit and human cerebral vasculature.
Participant Demographics
65 male New Zealand white rabbits, weighing 2.8 ~ 3.1 kg.
