The experiment was performed in 30 Wistar rats. In first (control) group (15 rats) animals received intraventricular injection of 40 microl autologous blood with 10 microl normal saline. In second group (15 rats) 40 microl autologous blood with 10 microl t-PA recombinant tissue plasminogen activator (t-PA) was injected in ventricular of the animals. Morphological examination of the brains were carried out 2 days and 21 days following IVH. Marked losses of the ependymal covering of the ventricular walls, choroids plexus were founded in bouth groups. The results indicate that intraventricular administered t-PA significantly enhanced the lysis of intraventricular blood clots, but r-PA (in second group) promoted delayed periventricular white matter edema formation (more 21 days).</p>  <p> </p> <p> </p></abstract><trans-abstract xml:lang="ru"><p>Цель исследования – установить в условиях эксперимента характер и степень выраженности морфологических изменений сосудистых сплетений и стенок желудочков мозга в различные сроки после введения в них крови и определить эффективность тканевого активатора плазминогена – «Актилизе». Эксперимент проведен на 30 белых крысах-самцах линии Вистар. Установлено, что при введении в боковой желудочек мозга животных крови вместе с физиологическим раствором наблюдались резко выраженные деструктивные изменения эпендимы и сосудистых сплетений, гемолиз эритроцитов, а также отек субэпендимального белого вещества, который не определялся к 21-м суткам. При введении в желудочки мозга крыс крови вместе с «Актилизе» также наблюдался гемолиз эритроцитов и выраженный отек суб- эпендимального белого вещества, которые выявлялись в более ранние сроки по сравнению с контрольной группой, при этом отек сохранялся и к 21-м суткам.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Experimental intraventricular haemorrhage</kwd><kwd>morphological examination of the brains</kwd><kwd>recombinant tissue plasminogen activator</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>кровь в желудочках мозга</kwd><kwd>морфологические изменения</kwd><kwd>влияние тканевого активатора плазминогена в эксперименте</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Колтовер А.Н., Верещагин Н.В., Людковская И.Г. и др.
