Case Reports[Endoscopic fenestration of median supratentorial cerebrospinal fluid cysts].
Mid-supratentorial liquor cysts are a relatively rare and generally congenital abnormality of the cerebral ventricles and subdural spaces. The data and views available in the literature on rational surgical policy is contradictory. The authors' experience in treating 16 patients was used to consider whether endoscopic techniques can be employed for invasive fenestration of the cysts. ⋯ It is concluded that endoscopic internal bypass surgery in patients wit median cystic liquor malformations is the treatment of choice. When equipment is adjusted, fenestration of the membranous walls of these cysts by using an endoscope is reliable and safe. Such patients may be recommended endoscopic technology used as the method of choice.

Comparative Study[The permeability of the hemato-encephalic barrier and the proteolytic potential of the cerebrospinal fluid in severe craniocerebral trauma].
To study blood-brain barrier permeability and proteolytic changes in in patients with severe brain injury and to evaluate their impact on its course and outcome, the concentrations of albumin, plasminogen (plasmin), alpha 2-macroglobulin, alpha 2-antiplasmin, and alpha 1-antitrypsin were examined in 58 victims by enzyme immunoassay. The control group comprised 20 patients examined for lumbar discal hernia. The studies indicate that early severe brain injury showed blood-brain barrier dysfunction whose severity can be detected by the spinal fluid levels of albumin, plasminogen, and alpha 2-macroglobulin. Proteolytic changes in spinal fluid are determined by its albumin, plasminogen (plasmin), alpha 2-macroglobulin, alpha 2-antiplasmin, and alpha 1-antitrypsin concentrations and affect the development of secondary brain lesion and they are of practical value.

Comparative Study[The surgical treatment results in intracranial meningiomas over 40 years].
A comparative study was made of the results of surgical treatment of 292, 290 and 349 patients with intracranial meningioma operated, respectively, in 1946-1966, 1970-1980, 1986-1996. The results were compared by radicality and postoperative lethality. The picture by these two parameters was the following in the above three periods: radicality--69.9%, postoperative lethality--17.8%; radicality--81%, lethality--15.5%, radicality 72.5%, lethality--5.2%. It is evident that, with time, the results of the surgery were constantly improving.
