However there are no clear evidence and research related to this issue. Thiamine itself was founded in 1990’s and has been used extensively as labour augmentation in 1940–1960’s. Main hypothesis previously due to B1 increased function of the uterine body and lower uterine segment obliteration during labour which also responsible for the reduction of pain. Thiamine also assumed to promote stimulation of uterine contractions by direct participation in nerve impulses that regulates and establish the rhythm of uterine contractions and also inhibits action of cholinesterase which reduce acetylcholine clearance. However recent research proves B1 mainly function in Krebs cycle specifically in decarboxylase of pyruvate to acetyl-CoA in form of thiamin diphosphate, synonymously known as thiamine pyrophosphate. Due to clear foundings of B1 function in cell energy metabolism, study of B1 in labour augmentation was not continue further. It’s also related to uterine contraction function in labour not relied on it’s paracervical parasympathetic ganglia which respond to acetylcholine but rely heavily on oxytocin and its receptor. As conclusion, the author stated B1 have no effect on labour progression however could prove beneficial if the mother has B1 deficiency as it’s could reduce energy output from cell which could affect myometrial contraction.</p></abstract><trans-abstract xml:lang="ru"><p>В Индонезии тиамин (витамин B1) используется для подготовки шейки матки и усиления сокращений матки в акушерских центрах и госпиталях благодаря его эффектам «вне зарегистрированных показаний». Однако в этой связи отсутствуют четкие доказательства его эффективности и соответствующие исследования. Тиамин изучался в 1990-х годах и широко использовался для стимуляции родов в 1940–1960-х годах. Основная гипотеза заключалась в том, что витамин B1 усиливает функцию тела матки и облитерацию нижнего сегмента матки во время родов, с чем также связано уменьшение боли. Также считалось, что тиамин способствует стимуляции сокращений матки путем прямого участия в передаче нервных импульсов, которые регулируют и устанавливают ритм сокращений матки, а также подавляет действие холинэстеразы, которая снижает клиренс ацетилхолина. Однако недавние исследования доказывают, что витамин B1 в основном участвует в работе цикла Кребса, а именно, в декарбоксилировании пирувата в ацетил-КоА в форме тиаминдифосфата, известного как тиаминпирофосфат. Тем не менее, несмотря на конкретные данные о функции витамина B1 в энергетическом метаболизме клеток, изучение его роли в стимуляции родовой деятельности продолжено не было. Кроме того, данный витамин также связан с сокращениями матки при родах, не зависящими от ее парацервикальных парасимпатических ганглиев, которые реагируют на ацетилхолин, но в значительной степени зависят от окситоцина и активации его специфического рецептора. В заключение был сделан вывод о том, что витамин B1 не влияет на прогрессирование процесса родов, однако может оказаться полезным при дефиците B1 у матери, поскольку он может снизить дефицит энергии в клетках и повлиять на сокращение миометрия.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>тиамин</kwd><kwd>В1</kwd><kwd>сокращение матки</kwd><kwd>ацетилхолин</kwd><kwd>стимуляция родовой деятельности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>thiamine</kwd><kwd>B1</kwd><kwd>uterine contraction</kwd><kwd>acetylcholine</kwd><kwd>labour augmentation</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Carpenter K.J.
