[The blood-brain barrier. II. Pathology: brain tumors, brain edema, hypertension, epilepsy]

In the first part of the publication the authors presented the blood-brain (BBB) under physiological conditions. The second part includes the current opinions concerning BBB during various disorders of the central nervous system (CNS) and hypertension. The imbalance of BBB is often not only a consequence of a pathologic status, but can be also cause of it. On the other hand BBB influences the therapy of many illnesses by restricting the penetration of drugs to the CNS.
