МАТЕРИАЛЫ И МЕТОДЫ. В исследовании на первобеременных крольчихах (n = 6) получены 37 образцов АЖ, в которых определены масса плода, масса плодной части плаценты, объем, осмоляльность и концентрации ионов Na+, K+, Cl− , Pi и Ca2+. РЕЗУЛЬТАТЫ. Установлены референтные пределы объема (0,09–1,63 мл), осмоляльности (210,0–267,0, мОсмоль/кг) и концентрации ионов Na+ (110,0–146,0 ммоль/л), K+ (6,0–12,4 ммоль/л), Cl− (87,0–117,0 ммоль/л), Ca2+ (1,88—2,89 ммоль/л) и Pi (0,56—1,57 ммоль/л) в АЖ. Обнаружена обратная корреляция объема АЖ с массой плода (r = –0,525, p &lt; 0,001), а также положительная корреляция между массой плода и осмоляльностью АЖ (r = 0,375, p = 0,022). Концентрации ионов Na+, K+, Clкоррелировали с массой плаценты (r = 0,368, p = 0,025; r = 0,353, p = 0,032; r = 0,381, p = 0,020 соответственно). Осмоляльность АЖ коррелировала с концентрациями ионов Na+ (r = 0,514, p &lt; 0,001) и Cl– (r = 0,510, p &lt; 0,001). ЗАКЛЮЧЕНИЕ. Полученные результаты могут быть использованы для разработки животных моделей влияния лекарственных препаратов на объем, осмоляльность и ионный состав АЖ на поздних сроках беременности</p></abstract><trans-abstract xml:lang="en"><p>THE AIM: to determine reference limits of volume, osmolality and concentration of Na+, K+, Cl−, non-organic phosphate (Pi ), and Ca2+ in amniotic fluid (AF) of rabbits on 27-28 day of gestation. MATERIALS AND METHODS: during research on first-pregnant rabbits (n=6), received 37 samples of AF, determined fetal mass, fetal part of placenta mass, volume, osmolality and concentration of Na+, K+, Cl−, Pi , and Ca2+. RESULTS: obtained reference limits of volume (0,09–1,63 ml), osmolality (210,0–267,0, mOsmol/kg), concentration of ions Na+ (110,0–146,0 mmol/l), K+ (6,0–12,4 mmol/l), Cl– (87,0–117,0 mmol/l), Ca2+ (1,88– 2,89 mmol/l) and Pi (0,56–1,57 mmol/l) in AF. Reverse correlation of AF volume with fetus mass (r = -0,525, p &lt; 0,001) and positive correlation between fetus mass and AF osmolality (r = 0,375, p = 0,022) were determined. Concentrations of Na+, K+, Cl− are correlated with placenta mass (r = 0,368, p = 0,025; r = 0,353, p = 0,032; r = 0,381, p = 0,020, respectively). AF osmolality correlated with concentrations of Na+ (r = 0,514, p &lt; 0,001) and Cl(r = 0,510, p &lt; 0,001). CONCLUSION: results could be used for developing animal models of medicamental influence on AF volume, osmolality and ion composition on late gestation. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>амниотическая жидкость</kwd><kwd>беременность</kwd><kwd>кролики</kwd><kwd>плод</kwd><kwd>электролиты</kwd><kwd>осмоляльность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>amniotic fluid</kwd><kwd>gestation</kwd><kwd>rabbits</kwd><kwd>fetus</kwd><kwd>electrolytes</kwd><kwd>osmolality</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">Brace RA, Cheung CY.
