Blood-brain barrier

Scientists have been able to commit such a break through the blood-brain barrier. (BBB)

  • A group of Canadian doctors from Sunnybrook Health Sciences Centre for the first time was able to deliver chemotherapy drugs directly into the brain using ultrasound, says CTV News.
  • Doctors first entered the drug intravenously with mikrosokopicheskim air bubbles. After doctors by means of ultrasound bubble forced to contract and expand in the required areas of the brain.
  • Thus it was possible to create gaps in the network cells of the BBB. The latter is a kind of protection against microbes and toxins filter between the central nervous system and circulatory system.
  • Thanks to the “holes”, doctors were able to deliver the drug directly into the brain of the patient. After the air bubble remains in the circulatory system and is absorbed entering the lungs. A hole formed in the blood-brain barrier without interference disappears after 8-12 hours.
