A Twist in the Tail

Researchers in the UK have found that margatoxin, a natural product found in scorpion venom and known to block potassium channels in blood vessels can prevent neoinitimal hyperplasia – the formation of scar tissue in blood vessels following coronary artery bypass graft surgery – which often causes the grafts to fail.

The research is in the very early stages and margatoxin itself could not be used as a post-operative drug because of its toxicity. However, a derivative or related compound might be developed for further investigation, and may one day lead to a drug for preventing scarring after bypass surgery.
