Cerebral infarction improved by safflower treatment

Area of Science:

• Neuroscience
• Pharmacology
• Biochemistry

Background:

• Cerebral infarction, a leading cause of death and disability, lacks effective treatments.
• Neurotransmitter imbalances, including norepinephrine (NE), dopamine (DA), and serotonin (5-HT), are implicated in ischemic stroke.
• Traditional remedies like safflower are being investigated for neuroprotective properties.

Purpose of the Study:

• To investigate the protective effects of safflower on cerebral infarction in a Mongolian gerbil model.
• To evaluate the impact of safflower on neurological deficits, neurotransmitter levels, and mortality following induced ischemia.

Main Methods:

• 152 Mongolian gerbils underwent middle cerebral artery occlusion to induce cerebral infarction.
• Neurological deficit scores were assessed, and brain tissue (cerebral hemispheres, brain stem) was analyzed for NE, DA, and 5-HT levels.
• Stroke index and mortality rates were compared between safflower-treated, untreated, and sham-operated groups.

Main Results:

• Untreated gerbils showed significant declines in NE, DA, and 5-HT in the affected hemisphere compared to controls.
• Safflower treatment prevented these neurotransmitter declines and significantly reduced the mean stroke index (2.1 vs. 7.8).
• Mortality was reduced by 29.7% in safflower-treated animals, which also exhibited a benign clinical course.

Conclusions:

• Safflower exhibits significant protective and beneficial effects against cerebral ischemia in gerbils.
• Safflower may mitigate ischemic brain damage by preserving neurotransmitter levels and reducing stroke severity.
• These findings support further research into safflower as a potential therapeutic agent for stroke.
