Ginkgo Biloba: Plant-Based Proarrhythmic Potential?

Ginkgo biloba is a commonly used herbal supplement in the United States. We describe a 63-year-old man with a significant ventricular ectopic burden (32.7%) that was refractory to metoprolol tartrate (41.

A novel method for the evaluation of proximal tubule epithelial cellular necrosis in the intact rat kidney using ethidium homodimer.

Background: Ethidium homodimer is a cell-membrane impermeant nuclear fluorochrome that has been widely used to identify necrotic cells in culture. Here, we describe a novel technique for evaluating necrosis of epithelial cells in the proximal tubule that involves perfusing ethidium homodimer through the intact rat kidney. As a positive control for inducing necrosis, rats were treated with 3.
