Effect of active fraction of cerebral on expression of caspase-3 and beta-amyloid precursor protein during therapy of hemorrhagic stroke in the acute and delayed periods.

Active anti-stroke fraction of Cerebral preparation (extract of water-soluble molecules from brain tissue of animals with hemorrhagic stroke) decreased caspase-3 expression and improved survival of experimental animals in the acute period after hemorrhagic stroke.

Detection of polyomavirus DNA in human brain tumors.

Aim: To investigate surgically resected human brain tumors for the presence of polyomavirus DNA.

Materials And Methods: 65 samples of surgically resected human brain tumors (57 tumors were of neuroectodermal genesis, 4--mesenchimal, 4--metastatic tumors) were examined for the presence of viral DNA by PCR analysis.

Results: DNA of polyomaviruses was found in oligodendroligomas (66.
