Abstract:

Blueberry anthocyanin-enriched extracts (BAE) at three doses (0.5, 1.0, and 2.0 g/kg) were administered by oral gavage to rats exposed to 10 mg/kg fine particulate matter (PM2.5) three times a week. A positive control group was exposed to PM2.5 without BAE treatment. We analyzed heart rate (HR), electrocardiogram (ECG), and histopathology, and biomarkers of cardiovascular system injuries, systemic inflammation, oxidative stress, endothelial function, and apoptosis. Results indicated that BAE, particularly at 1.0 g/kg, improved ECG and decreased cytokine levels in PM2.5-exposed rats. These changes were accompanied by an increase in interleukin 10 levels and superoxide dismutase activity in heart tissue and Bcl-2 protein expression, as well as a decrease in interleukin 6, malondialdehyde, endothelin 1, and angiotensin II levels and a reduction in Bax protein expression. This study demonstrates that BAE at certain doses can protect the cardiovascular system from PM2.5-induced damage.
