The activity of γ-glutamyltransferase in the peripheral blood of pregnant women was determined by spectrophotometry at the device «Stat-Fax-2100» (The USA). Hsp-70 and caspase-3 in placenta homogenate were found out with serological methods. The activity of glutamatdehydrogenase and pyridoxal-5-phosphatase was studied with histochemical method of Z. Loyd at the placenta slice of parturient women. The apoptotic changes in syncytiotrophoblast nuclei were defined by ISEL-method.</p><p><bold>Results</bold>. The peripheral blood of CMV-seropositive parturient women showed a reduction of γ-glutamyltransferase in 1.30 times. Histochemically we identified the reduction of reaction products' concentration in response to pyridoxal-5-phosphate by 2.14 times, to glutamatdehydrogenase by 1,57 times. At the same time there was an increase of caspase-3 in 2,8 times and reduction of Hsp70 in 2.6 times in placenta homogenate. The number of apoptotic changes in syncytiotrophoblast nuclei increased by 4 times.</p><p><bold>Conclusion</bold>. Worsening of CMV infection in the period 25–28 weeks of pregnancy leads to disruption of amino acid metabolism in the placenta, causing structural and functional and metabolic adjustment, and is one of the reasons for slow growth and lack of development of the fetus. </p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель исследования</bold>: установить закономерности нарушений трансаминирования в синцитиотрофобласте ворсинок плаценты после перенесенного обострения цитомегаловирусной инфекции (ЦМВИ) в третьем триместре беременности.</p><p><bold>Методы</bold>: обследовано 30 рожениц с обострением ЦМВИ на сроке 25–28 нед беременности. Гамма-глутамилтрансферазу в периферической крови определяли спектрофотометрическим методом, белок Hsp70 и каспаза-3 в гомогенате плаценты — серологическими методами, активность глутаматдегидрогеназы и пиридоксаль-5-фосфатдегидрогеназы на срезах плаценты — гистохимическим методом по З. Лойда, апоптотические изменения ядер синцитиотрофобласта — по ISEL-методу.</p><p><bold>Результаты</bold>: в периферической крови ЦМВ-серопозитивных рожениц выявлено снижение в 1,30 раза гамма-глутамилтрансферазы; гистохимически на срезах плаценты установлено снижение содержания продуктов реакции на пиридоксаль-5-фосфатдегидрогеназу в 2,14 раза, на глутаматдегидрогеназу — в 1,57; в гомогенате плаценты отмечалось увеличение содержания каспазы-3 в 2,8 и снижение белка Hsp70 в 2,6 раза; количество апоптотически измененных ядер в синцитиотрофобласте ворсинок плаценты увеличилось в 4 раза.</p><p><bold>Заключение</bold>: обострение ЦМВИ на сроке 25–28 нед беременности приводит к нарушению обмена аминокислот в плаценте, что вызывает структурно-функциональные и метаболические перестройки и является одной из причин замедления роста и недостаточности развития плода.</p></trans-abstract><kwd-group xml:lang="en"><kwd>cytomegalovirus infection</kwd><kwd>transamination</kwd><kwd>syncytiotrophoblast</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>цитомегаловирусная инфекция</kwd><kwd>трансаминирование</kwd><kwd>синцитиотрофобласт</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
